200812545 九、發明說明： 【發明所屬之技術領域】 本發明係有關脈波檢測裝置’特別是有關進行用以脈波檢 測之感測器的定位操作之脈波檢測裝置。 【先前技術】 在使用脈波計來測定受測者（患者等）之脈波時，於被測定 的脈波中，係檢測有從心臟推出血流之壓力波（驅出波），及 來自末端的反射壓力波（反射波）。且藉由測定含有驅出波及 反射波的脈波，可以知道該受測者之血管硬化（老化）程度。 因而，測定脈波因爲可知道該被測者之健康狀態故非常地重 要。 以往的脈波檢測裝置係具備有安裝在手腕等測定部位的 感測器單元。在禪定時，受測者等係以最佳的測定位置，亦 即使感測器單元移動到動脈之位置。籠統的對合位置係依手 工來操作，而微調整則係實際地一邊測定脈波一邊辨別動脈 位置。 如此的脈波檢測裝置，例如係揭示於日本國專利公開 200 3-3 25 4 63號公報和專利公開2004-222847號公報中。此等 文獻所記載之裝置係具有將最終決定的位置作成音調圖 (tonogram)而顯示在顯示單元之畫面上的機能。音調圖係用 以表示由感測器單元之脈波感測器所檢測的脈壓之分布。而 在微調整時一邊看所顯示的音調圖一邊移動感測器單元，而 探索最佳的位置。 專利文獻1 :日本國專利公開2003-325463號公報 200812545 專利文獻2 :日本國專利公開2004-222847號公報 【發明內容】 發明欲解決的課題 然而，於日本國專利公開2003-325463號公報和專利公開 2004-222847號公報所揭示的裝置中，應使裝在手腕的感測 器單元移動的方向與所顯示的音調圖指示的動脈位置之方 向難以對應。亦即，受測者僅看音調圖，係難以判斷應將感 測器單元移動於那個方向才好。 又、脈波裝置大多用於醫療機關等，但音調圖，是否指依 從穿戴在感測器單元之受測者視點的脈壓分布，或指依從操 作者（醫生等）視點的脈壓分布乃未有明示的顯示。因而，不 論是受測者還是測定者都難以從音調圖明確地掌握應使感 測器單元移動於哪個方向。 因而、本發明之目的係提供一種隨著觀看用以表示所檢出 的測定部位之脈壓分布的圖表方向而進行切換顯示的脈波 檢測裝置。 本發明之其他目的爲提供一種因應所檢測測定部位之脈

陣列之標記與著色標記中任一個著色標記的對合位置之資 料而指示應予滑移的方向。 較佳爲，壓力感測器陣列係收容於框體，能夠在框體內滑 移操作於排列方向。在壓力感測器陣列之外面印刷有標記。 在框體，從外部能夠確認的開口部係被形成於滑移的方向。 並於框體之表面，在開口部之周圍印刷有複數個不同的文字 或記號’顯示控制部，係藉由顯示用以指示壓力感測器陣列 200812545 之標記與複數個不同文字或記號中任一個之記號或文字對 合位置的資料而指示應予滑移的方向。 較佳爲、方向指示資料係依從看所顯示圖表的視點之不 同，使用從該視點所看到之收容有壓力感測器陣列的框體之 圖樣來指示應予滑移的方向。 依據本發明其他形態，係一種程式產品，係使電腦執行脈 波檢測裝置中之顯示，該脈波檢測裝置具有：壓力感測器陣 列，具有排列複數個壓力感測器的面，該面在生物體之動脈 上被推壓成該壓力感測器之排列方向與該動脈交叉；推壓 部，將該壓力感測器陣列之面推壓於該動脈上，其特徵爲具 備如以下者。 亦即程式產品，係使電腦執行如下步驟：從被推壓部推壓 的壓力感測器陣列之一方端之壓力感測器開始，一直到配置 於另一方端的壓力感測器爲止，按排列中的壓力感測器之排 列次序，作成將各壓力感測器輸出的壓力資料連續標繪之圖 表資料的步驟，及根據作成圖表的步驟所作成之圖表資料的 圖表，控制顯示於顯示部的步驟。而在顯示控制步驟中，係 將與外部賦予的切換指示對應的以下任一個圖表顯示於顯 示部，其中該圖表係指：於面被推壓的狀態下，從隔著平面 之一方側的視點所看的圖表，而該平面係配置有壓力感測器 陣列且含有與動脈交叉的方向；以及從隔著平面的另一方側 之視點所看的圖表。 較佳爲，在控制顯示的步驟，因應於自外部賦予的切換指 示，將於顯示部從顯示的一方側視點所看圖表，切換顯示爲

;用以表示依音調圖作成部204作成的音調圖 資料之音調圖資料301 ;用以表示與依脈波處理部2〇6所得 的脈波資訊有關的脈波資訊302 ;以及用以表示被顯示於顯 示器24之對話資料的患者用顯示資料（A側）及（B側）3〇3及 • 305、以及操作者用顯示資料（人側）及（6側）3〇4及3〇6。此等 資料303〜306之詳細容後述之。 於上述構成中，在血壓測定之際，血壓算出部201係根據 透過通信電路71而輸入的壓力信號，按規定之演算式，算 出血壓（mmHg)(相當最高血壓之收縮壓（syst〇Hc blood pressure)及相當最低血壓之舒張壓（diastolic blood pressure))以及脈博數（pulse : beat/minute))。如此算出之次序 因爲可適用於以往所提供之習知次序，所以在此省略其詳細 ® 說明。此外、以下亦將如此算出的血壓値、或血壓値及脈博 數稱爲「血壓測定値」。於本實施形態中、血壓測定値，係 以每一血壓測定就輸出於記憶體控制部203。記憶體控制部 203，係將輸入的血壓測定値，作爲與從計時器43輸入的時 刻資'料（測定時刻資料）對應的血壓資料 300而儲存在 RAM22。顯示控制部202係把從RAM22讀出的血壓資料300 顯示在顯示器24。此外、顯示控制部202，係把從計時器43 輸入的現在時刻資料顯示於顯示器24。 -14- 200812545 參照第1圖和第3圖、操作部23係含有用以指示切換在 顯示器24中的音調圖之顯示形態而被操作的開關23A和 23B、以及用以指示開始和停止測定而被操作的開關23C和 23D。 第6圖表示感測器單元1之構成。第6圖（A)之感測器單 元1之橫斷穿戴手腕時手腕方向之剖面構造表示於第6圖 (B)。第6圖（C)係把第6圖（B)之點線框內之一部分放大表 示。在第6圖（B)之推壓腕帶13 —被加壓泵14及負壓泵15 • 調整腕帶壓力時，隔著由陶瓷或樹脂所成型的塊而安裝的壓 ，力感測器陣列1 1係如第6圖（C)所示箭頭25方向僅自由地移 動因應於該腕帶壓力位準的量。壓力感測器陣列11係藉移 動於箭頭25之下面方向（手腕方向），而從框體1 00預先所設 開口部突出而推壓於手腕表面。如第6圖（D)和第6圖（E)所 示，壓力感測器陣列11之複數個壓力感測器26的排列方向 在是將感測器單元1穿戴在手腕時對應於與動脈大致正交 (交叉）的方向，排列長度係至少比動脈之徑長。在各個壓力 ^ 感測器26被推壓腕帶13之腕帶壓力所推壓時，把從動脈發 生並傳達於生物體表面之屬壓力振動波（脈壓）的壓力資訊作 爲電壓信號輸出。壓力感測器26係於規定之大小（5.5mm X 8.8mm)之推壓面40，例如排列40個。第6圖（A)之用以引導 感測器單元1的滑移方向的槽9所延伸方向，係對應於壓力 感測器陣列11之壓力感測器26的排列方向。 第7圖表示沿第4圖VII - VII線的剖面圖。在第7圖中、 推壓腕帶13之腕帶壓力因爲被負壓泵15充分減壓（因爲具 -15- .200812545 有遠低於大氣壓的壓力位準），所以壓力感測器陣列1 1係成 爲被收容在感測器單元1之框體1 〇〇內的狀態而不接觸於手 腕表面。 在本實施形態中、在脈波測定時，係透過顯示器24顯示 用以表示由壓力感測器陣列1 1所檢測的脈壓分布的音調 圖。因此，透過音調圖可對使用者報知固形物或徺骨動脈27 所位在的方向，。使用者透過音調圖，可以確認橈骨動脈27 之方向，亦即應使感測器單元1滑動的方向。針對此報知之 # 詳細內容將叙述如後。 在此、針將感應器單元1滑動的方向作說明。如同上述、 在將感測器單元1穿戴在手腕上時，複數個壓力感測器26 之排列方向係對應於與徺骨動脈27大致正交（交叉）的方 向，由槽9所引導的感測器單元1之滑移方向，係對應於壓 力感測器26的排列方向。因此，感測器單元1之滑移方向， 係對應於與橈骨動脈27大致正交（交叉）的方向。 第8圖和第9圖係顯示著被印刷（列印）於感測器單元1之 ® 框體100的標記61和62(附有文字‘A’和‘B，的箭頭）。 第8圖之標記6 1係於收容感測器單元1的框體100側面， 從既將感測器單元1穿戴在手腕狀態之患者側以可確認地把 由槽9所引導之可滑移操作方向印刷成—、—，同時各箭頭 附上並印刷有一味地指示朝向的文字（‘ A ’和‘ B ’ ）。在 此、可滑移操作的方向係以文字和箭頭之組合的圖樣來表 示，但若可指示方向的話、則亦可爲其他的文字、數値、圖 形等之圖樣。 -1 6 - 200812545 於患者之手腕上穿戴著感測器單元1的狀態（參照第4圖） 時，標記6 1和62之文字‘ A，係指患者之左測，文字‘ b， 係指患者之右側。因此，在穿戴著感測器單元1之狀態中， 將感測器單元1滑動於文字‘ A’側，係指位在患者側的人 (患者或操作者）要進行滑動於其人之左側的操作，而將感測 器單元1滑動於文字‘ B’側，係指要進行滑動於其人之右 側的操作。 又，於患者手腕上穿戴著感測器單元1的狀態（參照第4 Φ 圖），位在與患者隔著感測器單元1而相對之位置的人（操作 者），標記61和62之文字‘ A’ ，係指其人（操作者）之右側， 文字‘ B ’係指左側。所以在將感測器單元1穿戴的狀態， 其人將感測器單元1滑動於文字‘ A’側，係指滑動操作於 其人之右側，而滑動於文字‘ B’側，係指滑動操作於其人 之左側。在此雖未圖示，但在感測器皐元1之框體100，位 在與患者隔著感測器單元1而相對之位置的人（操作者）側邊 之面上亦印刷有如第8圖般的標記6 1。 ® 第9圖（A)和（B)之標記62，係於收容感測器單元1的框體 1 00的上面，以穿戴感測器單元1在手腕狀態之患者，或操 作者可確認般地，把應使引導感測器單元1滑動到槽9的方 向印刷成—、—，同時各箭頭附有印刷著一味地表示朝向的 文字（‘ A’和‘ B’ ）。 又，如第9圖（A)和（B)所示，在框體100上面之一部分形 成有開口部（窗）67。又、感測器單元1之上面印刷有標記66。 伴隨著感測器單元1被槽9所引導並滑移，標記66亦移動 -17- 200812545 於滑動開口部內的方向。 在此、參照第9圖（A)，於收容感測器單元1的框體1〇〇 上面’隔著開口部67 ’在一方側上印刷有複數個棒狀之標記 64 ’在另一方側，亦在與此等棒狀標記各自對應的位置上印 刷有棒狀標記64。各個棒狀標記係用不同的顏色著色，且位 在隔著開口部67呈對應的位置之棒狀標記彼此係以相同顏 色著色。 第9圖（B)係顯示代替第9圖（A)之棒狀標記圖樣而印刷有 文字（在此係數値）所構成的標記65。有關用標記65表示的 數値’係指位在隔著開口部67對應的位置之數値彼此是指 同樣的値。 在利用槽9之引導來滑移操作感測器單元1時，操作使感 測器單元1之標記66配合於標記64之任何一個顏色之棒狀 標記、或是標記65之任何一個値之數値位置。針對此操作 之目的容後述之。 按第1 0圖之流程圖來說明本實施形態的處理次序。依照 該流程圖的程式，及於實行該程式時所參照的資料係預先儲 存在ROM21或RAM22，使CPU20邊適宜參照該資料邊讀出 程式來實行而進行處理。此外、在此係假定顯示單元3被供 •給電源而處於可動作的狀態。 首先使用者開啓（ON)操作部23之電源開關（未圖示）。 CPU20係響應該ON操作而透過通信電路18對控制電路17 指示把切換閥16切換到負壓泵15側以驅動負壓泵15(步驟 S 1)。因此、控制電路17係根據指示，切換切換閥1 6來驅 200812545 動負壓泵15。 負壓泵15 —被驅動時，使腕帶壓力透過切換閥16以遠低 大氣壓的壓力作用，所以壓力感測器陣列11係在第6圖（C) 之箭頭25之移動於上箭頭方向。此結果，可以迴避壓力感 測器陣列11不小心突出而導致錯誤動作或發生故障。 其後，在測定者將感測器單元1如第4圖那樣穿戴在手腕 上並開啓操作部23之起動開關23C時，隨著CPU20之指示 信號，控制電路1 7判定壓力感測器陣列1 1是否移動，亦即 判定感測器單元1是否已沿著滑動槽9滑移到手腕之表面上 的位置（S2)。在感測器單元1之框體1〇〇內設有檢測滑移用 的未圖示之微動開關，控制電路17係根據該微動開關之檢 測信號來判定壓力感測器陣列1 1是否有移動。 在未判定有移動之期間（步驟S2爲否），係反覆步驟S 1 之處理。而在判定爲有移動時（步驟S2爲是），控制電路就 根據從操作部23所賦予的操作信號來判定開關23C是否被 操作（步驟S2a)。在判定結果爲開關23C未被操作、亦即指 未指示開始測定時（步驟S2a爲否），返回步驟S1之處理， 以後，係一直到開關23C被操作之前，反覆步驟S 1和S2 之處理。 一方面，在步驟S2a之判定結果爲操作了開關23C時，亦 即指已被指示開啓測定時（步驟S 2 a爲是），控制電路17係把 切換閥16切換成加壓泵14側以驅動加壓泵14(步驟S3)。依 此、腕帶壓力上升使壓力感測器陣列11移動於第6圖（C)之 箭頭25之下箭頭方向，壓力感測器陣列1 1係被推壓於手 -19- 200812545 腕之表面。 在壓力感測器陣列1 1 一被推壓於手腕表面上（參照第7圖） 時’電壓信號之壓力資訊（指脈壓的資訊）係由各壓力感測器 26藉由多工器12而被導出，利用A/D轉換器19轉換爲數位 資訊，並藉由通信電路1 8而賦予顯示單元3之音調圖作成 部204。此時，從壓力感測器陣列1 1配列的一方端之壓力感 測器26 —直到另一方端之壓力感測器26爲止，壓力資訊係 按照其位置之次序而被賦予音調圖作成部204。音調圖作成 Φ 部204係使用被賦予的數位資訊（壓力資訊）來作成音調圖， 再將作成的音調圖之資料301輸出於記憶體控制部 203 (S3a)。記憶體控制部203係將被賦予的資料儲存於 RAM22。 此時，切換部205係根據從操作部23輸入的切換之操作 信號，現在，判定是否被指定而將音調圖之顯示按操作者視 點及患者視點之任何一形態而作切換（步驟S4)。在此，係預 先假設由患者或操作者操作了開關23A或23B。因此、例如， ® 在開關23A被預先操作時，根據該操作所輸入的切換操作信 號，切換部205係指示顯示控制部202顯示患者視點所用之 音調圖，但是在開關23 B被預先操作時，係根據該操作所輸 入的切換操作信號，指示顯示控制部202顯示操作者視點所 用之首調圖。 顯示控制部202，係從RAM22讀出音調圖資料301，根據 所讀出的資料，而依從切換部205所賦予的指示，把音調圖 顯示於顯示器24(步驟S5、S6)。在此、音調圖之顯示形態， -20- .200812545 係依從切換部2 0 5所賦予的指示而變更。而針對被作成並顯 示的音調圖將於後述。 其次、脈波處理部206係根據音調圖來執行腱29除外之 固形物的處理（步驟S 7)’在固形物除外的處理中，係根據在 S 3 a所獲得的音調圖資訊，特定在壓力感測器陣列1 1中之位 於固形物上的壓力感測器26，而被特定的壓力感測器26除 外的剩下之壓力感測器26，係被候補選爲位在橈骨動脈27 上的壓力感測器26。 9 其次、脈波處理部206係從位於橈骨動脈27上的壓力感 測器26之候補，執行把位於撓骨動脈27上的壓力感測器26 選爲最佳通道的處理（步驟S 8)。有關此最佳通道選擇處理之 詳細係詳述於專利文獻2之日本國專利公開2004-222847號 公報中，在此係簡單地說明。 音調圖資料3 01，係針對各壓力感測器26，包含有由該壓 力感測器26檢測的脈壓信號所表示之直流成分和交流成分 之資料。CPU20係將直流成分位準成爲一定臨限値以上的所 ® 有壓力感測器26特定爲未位在徺骨動脈27上。然後CPU20 係把所特定的壓力感測器26除外所剩下的壓力感測器26視 爲是位於榛骨動脈27上的壓力感測器之候補。然後從此候 補之中，直流成分之位準更低，且交流成分之位準更高的壓 力感測器26選爲最佳通道。 其次，脈波處理部206因爲根據從對應所選擇的最佳通道 之壓力感測器26輸入的壓力資訊而檢測脈波，所以算出基 於推壓腕帶1 3的推壓位準之變動量，再將算出的變動量與 -21 - 200812545 可檢測脈波的規定變動量作比較（步驟S9)。比較結果，若算 出的變動量滿足規定變動量則判定滿足用以脈波檢測的腕 帶壓力條件（步驟S 10爲是），而若未能滿足時則透過控制電 路1 7，利用加壓泵1 4 一邊繼續對推壓腕帶1 3加壓一邊反覆 步驟S3a〜S 10之處理，直到滿足腕帶壓力條件爲止。 在滿足腕帶壓力條件時（步驟S 1 0爲是），調整加壓泵1 4 使得推壓腕帶1 3對壓力感測器陣列1 1的推壓位準可成爲脈 波檢測用之最佳位準（步驟S 11)。此調整之詳細係記載於專 利文獻2之日本國專利公開2004-222847號公報，在此省略 其詳細。 在針對推壓腕帶1 3做最佳壓力調整之下，被選爲最佳通 道的壓力感測器26所輸出的壓力資訊，亦即橈骨動脈27脈 波之波形資料，係藉由多工器12、A/D轉換器19及通信電 路18而轉送於脈波處理部206(步驟S12)。 脈波處理部206係受理波形資料，根據所受理的波形資料 做脈波檢測。在受理波形資料並判定結束脈波檢測之規定條 件成立以前係反覆步骤S 1 2之脈波資料轉送處理。此外、根 據所受理的波形資料之脈波檢測處理係按照公知之順序，所 以在此省略其詳細。 在脈波檢測結束之規定條件成立時（步驟S13爲是）、CPU20 係透過切換閥16而驅動負壓泵15般地作控制（步驟S 14)。 藉此而解除壓力感測器陣列11對手腕之推壓狀態，一連串 之脈波檢測處理係結束。 脈波處理部206，係將既檢測脈波之資訊輸出於記憶體控 -22- 200812545 制部203。記憶體控制部203，係將被賦予的資訊作爲脈波 資訊302儲存在RAM22。顯示控制部202，係從RAM22讀出 脈波資訊302,將讀出的脈波資訊302藉由顯示器24輸出到 外部。又、脈波之資訊，係被用於利用脈波處理部206來算 出AI(增加率索引；Augmentation Index)，也可使算出的AI 輸出於顯示器24。 在此、針對於步驟S3a、步驟S5(S6)作成（顯示）的音調圖 作說明。 • 第1 1圖係根據作成的音調圖資料3 0 1之顯示的一例子， 顯示與壓力感測器陣列1

Field of the Invention The present invention relates to a pulse wave detecting device', particularly to a pulse wave detecting device for performing a positioning operation of a sensor for pulse wave detection. [Prior Art] When a pulse wave is used to measure a pulse wave of a subject (patient, etc.), a pressure wave (exit wave) that is pushed out from the heart is detected in the pulse wave to be measured, and The reflected pressure wave (reflected wave) at the end. Further, by measuring the pulse wave including the evoked wave and the reflected wave, the degree of hardening (aging) of the blood vessel of the subject can be known. Therefore, it is very important to measure the pulse wave because it can know the health status of the subject. A conventional pulse wave detecting device includes a sensor unit attached to a measurement site such as a wrist. At the time of meditation, the subject is optimally measured, even if the sensor unit moves to the position of the artery. The general position of the joint is manually operated, while the micro-adjustment actually determines the pulse position while discriminating the position of the artery. Such a pulse wave detecting device is disclosed, for example, in Japanese Patent Laid-Open Publication No. Hei. No. 2003-222847. The devices described in these documents have the function of displaying the final determined position as a tonogram and displaying it on the screen of the display unit. The tone map is used to indicate the distribution of pulse pressure detected by the pulse wave sensor of the sensor unit. In the micro adjustment, while moving the sensor unit while looking at the displayed tone map, the best position is explored.

In the device disclosed in Japanese Laid-Open Patent Publication No. 2004-222847, it is difficult to correspond to the direction in which the sensor unit mounted on the wrist moves in the direction of the arterial position indicated by the displayed tone map. That is, the subject only looks at the tone map, and it is difficult to judge whether the sensor unit should be moved in that direction. Further, the pulse wave device is mostly used in medical institutions, etc., but the tone map refers to the pulse pressure distribution according to the viewpoint of the subject worn by the sensor unit, or the pulse pressure distribution according to the viewpoint of the operator (doctor, etc.).

A mark is printed on the outer surface of the pressure sensor array, and the opening portion of the frame from which the mark can be confirmed from the outside is formed in the direction of the slip. On the surface of the frame, a plurality of coloring marks of different colors ^ are printed around the opening. The display control unit indicates the direction to be slipped by displaying information indicating the matching position of the mark of the pressure sensor array and any one of the colored marks. Preferably, the pressure sensor array is housed in the housing and is slidable in the housing in the alignment direction. Marks are printed on the outside of the pressure sensor array. In the casing, an opening portion that can be confirmed from the outside is formed in the direction of slippage. And on the surface of the frame, a plurality of different characters or symbols 'display control unit are printed around the opening portion, by displaying the mark indicating the pressure sensor array 200812545 and a plurality of different characters or symbols. A mark or text that matches the position of the position indicates the direction in which it should be slipped. Preferably, the direction indicating data is in accordance with the viewpoint of the displayed chart, and the direction of the frame to be slipped is indicated by the pattern of the frame in which the pressure sensor array is seen from the viewpoint.

In the display control step, any one of the following graphs corresponding to the switching instruction given by the outside is displayed on the display unit, wherein the graph refers to a viewpoint from one side of the plane in a state where the surface is pressed. The chart is viewed, and the plane is configured with a pressure sensor array and contains a direction that intersects the artery; and a chart as viewed from the other side of the plane. Preferably, in the step of controlling the display, in response to the switching instruction given from the outside, the graph is displayed on the display unit from the side view of the display, and the graph displayed as the view from the other side is switched to 200812545.

The blood pressure measuring unit 50 connects the wristband 52 worn on the upper arm through the air tube 53. -12- 200812545 In addition, the fixed stage unit 7 and the display unit 3 of the fixed table 2 are separately provided, but the two functions can be built in the fixed stage 2. In the case where it is built, the operation unit 23 and the display unit 24 can be externally operated or can be attached to the frame of the fixed table 2 as it is confirmed from the outside. Fig. 2 shows the configuration of the blood pressure measuring unit 50 and its associated portion. Referring to Fig. 2, the blood pressure measuring unit 50 includes a pressure sensor 504, and the capacity changes depending on the pressure built in the air bladder 51 of the wristband 52 (hereinafter referred to as "the wristband pressure"); the oscillating circuit 55, the oscillating frequency signal corresponding to the capacity 値 of the pressure sensor 54 is output to the communication circuit 71 by the I/F 60; the pump 56 and the valve 58 for adjusting the wristband pressure level; for driving the pump 56 a pump drive circuit 57; and a valve drive circuit 59 for adjusting the degree of switching of the valve 58. The air bag 51 and the pressure sensor 54, the pump 56, and the valve 58 are connected by an air tube 53. The I/F 60 converts the signal obtained from the oscillation circuit 55 into a pressure signal (a pressure pulse wave signal indicating a change in the volume of the artery), and outputs it to the communication circuit 71. The functional configuration of the pulse wave detecting device according to the embodiment will be described with reference to Fig. 5. The pulse wave detecting device includes a blood pressure calculating unit 20 1 for calculating a blood pressure measuring port described later, a display control unit 202 for controlling display of information and data on the display unit 24, and a data storage for controlling the memory (RAM 22).

The dialog display control unit 207 instructs the display control unit 200812545 202 to display a predetermined dialog on the display 24. The function of the dialog display control unit 2〇7 is based on the fact that the position of the sensor unit 1 at the measurement site is not appropriate, in other words, when an error occurs, to display a predetermined dialogue. The RAM 22 stores: a blood pressure data 300 for indicating the blood pressure measurement (calculation) result data, and a tone map data 301 for indicating the tone map data created by the tone map creation unit 204; The pulse wave information 302 related to the pulse wave information obtained by 2〇6; and the patient display data (A side) and (B side) 3〇3 and 305, and the operation for indicating the dialogue data displayed on the display 24.

In the above-described configuration, the blood pressure calculation unit 201 calculates the blood pressure (mmHg) according to a predetermined calculation formula based on the pressure signal input through the communication circuit 71 (the systolic blood pressure (syst〇Hc blood) Pressure) and the diastolic blood pressure of a relatively minimum blood pressure and pulse (beat/minute). The order of calculation is omitted because it can be applied to the conventional order provided in the past. In addition, the blood pressure 値, or the blood pressure 値 and the pulse number calculated as described above are also referred to as "blood pressure measurement". In the present embodiment, the blood pressure measurement is output to the memory control unit 203 for each blood pressure measurement.

Further, the display control unit 202 displays the current time data input from the timer 43 on the display 24. -14- 200812545 Referring to Figs. 1 and 3, the operation unit 23 includes switches 23A and 23B for instructing switching of the display form of the tone map in the display 24, and for instructing start and stop of the measurement. The switches 23C and 23D are operated. Fig. 6 shows the construction of the sensor unit 1. The cross-sectional structure of the wrist direction when the sensor unit 1 of Fig. 6(A) is worn across the wrist is shown in Fig. 6(B). Fig. 6(C) shows an enlarged view of a part of the dotted line frame of Fig. 6(B). Pushing the wristband 13 in Fig. 6(B) - the pressurized pump 14 and the negative pressure pump 15 • When the wristband pressure is adjusted, the pressure sensor is attached via a block formed of ceramic or resin. The array 1 1 is only free to move in an amount corresponding to the pressure level of the wristband as indicated by arrow 25 in Fig. 6(C). The pressure sensor array 11 is moved in the lower direction of the arrow 25 (wrist direction) and protrudes from the opening provided in advance by the frame 100 to be pressed against the wrist surface. As shown in FIGS. 6(D) and 6(E), the arrangement of the plurality of pressure sensors 26 of the pressure sensor array 11 corresponds to the artery when the sensor unit 1 is worn on the wrist. In a direction that is substantially orthogonal (intersecting), the length of the arrangement is at least longer than the diameter of the artery. When the pressure sensor 26 is pressed by the wristband pressure of the wristband 13, the pressure information of the pressure vibration wave (pulse pressure) generated from the artery and transmitted to the surface of the living body is output as a voltage signal. The pressure sensor 26 is of a prescribed size (5. 5mm X 8. The pressing surface 40 of 8 mm) is, for example, arranged in 40 pieces. The direction in which the grooves 9 for guiding the sliding direction of the sensor unit 1 in Fig. 6(A) extend corresponds to the direction in which the pressure sensors 26 of the pressure sensor array 11 are arranged. Fig. 7 is a cross-sectional view taken along line VII-VII of Fig. 4. In Fig. 7, the wristband pressure of the wristband 13 is fully decompressed by the negative pressure pump 15 (because it has -15-. 200812545 has a pressure level far below atmospheric pressure), so the pressure sensor array 11 is in a state of being housed in the casing 1 of the sensor unit 1 without contacting the wrist surface. In the present embodiment, at the time of pulse wave measurement, a tone map for indicating the pulse pressure distribution detected by the pressure sensor array 11 is displayed through the display 24. Therefore, the user can be informed of the direction in which the solid or the iliac artery 27 is located through the tone map. Through the tone map, the user can confirm the direction of the radial artery 27, that is, the direction in which the sensor unit 1 should be slid. The details of this report # will be described later. Here, the direction in which the needle slides the sensor unit 1 will be described. As described above, when the sensor unit 1 is worn on the wrist, the arrangement direction of the plurality of pressure sensors 26 corresponds to a direction substantially orthogonal (crossing) with the radial artery 27, and the sense of being guided by the groove 9. The slip direction of the detector unit 1 corresponds to the direction in which the pressure sensors 26 are arranged. Therefore, the sliding direction of the sensor unit 1 corresponds to a direction substantially orthogonal (intersecting) with the radial artery 27. Figs. 8 and 9 show marks 61 and 62 (arrows with characters 'A' and 'B,) printed on (printed) on the housing 100 of the sensor unit 1. The reference numeral 6 1 of Fig. 8 is attached to the side of the casing 100 accommodating the sensor unit 1, and the slidable movement guided by the groove 9 is identifiable from the side of the patient wearing the sensor unit 1 in the wrist state. The direction of operation is printed as —, —, while the arrows are attached and printed with text indicating the orientation ('A' and 'B'). Here, the direction of the slidable operation is represented by a combination of characters and arrows, but if the direction is indicated, other characters, numerals, graphics, and the like may be used. -1 6 - 200812545 When the state of the sensor unit 1 is worn on the wrist of the patient (refer to Fig. 4), the characters 'A of the markers 6 1 and 62 refer to the left side of the patient, and the text ' b, refers to The right side of the patient. Therefore, in the state in which the sensor unit 1 is worn, the sensor unit 1 is slid on the side of the character 'A', and the person (patient or operator) positioned on the patient side is to be slid to the left of the person. The operation of sliding the sensor unit 1 on the 'B' side of the text refers to the operation to be slid to the right of the person. Further, the state in which the sensor unit 1 is worn on the wrist of the patient (refer to the fourth Φ map), the person (operator) positioned at a position opposed to the patient across the sensor unit 1, marks 61 and 62 The text 'A' refers to the right side of the person (operator), and the text 'B' refers to the left side. Therefore, in the state in which the sensor unit 1 is worn, the person slides the sensor unit 1 on the side of the character 'A', which means that the sliding operation is on the right side of the person and slides on the side of the text 'B', which means sliding Operate to the left of its people. Although not shown in the figure, the frame 100 of the sensor unit 1 is printed on the side of the person (operator) on the position opposite to the patient across the sensor unit 1. Figure 8 shows the mark 6 1. ® Figure 9 (A) and (B) are marked 62 on the upper side of the housing 100 of the sensor unit 1 to accommodate the patient in the wrist state of the sensor unit 1, or the operator can confirm The ground is printed in the direction in which the guide sensor unit 1 is slid to the slot 9, and the arrows are printed with characters ('A' and 'B') that are printed with a single orientation. Further, as shown in Fig. 9 (A) and (B), an opening (window) 67 is formed in one portion of the upper surface of the casing 100. Further, a mark 66 is printed on the upper surface of the sensor unit 1. As the sensor unit 1 is guided and slipped by the slot 9, the mark 66 also moves -17-200812545 in the direction of the sliding opening. Here, referring to FIG. 9(A), a plurality of bar-shaped marks 64' are printed on one side of the casing 1'''''''''''''''' A bar-shaped mark 64 is also printed at a position corresponding to each of the bar-shaped marks. Each of the bar-shaped marks is colored with a different color, and the bar-shaped marks located at corresponding positions across the opening portion 67 are colored with the same color. Fig. 9(B) shows a mark 65 formed by printing a character (in this case 値) instead of the bar-shaped mark pattern of Fig. 9(A). The number 値 indicated by the reference numeral 65 is the same as the number of positions corresponding to the position corresponding to the opening 67. When the operation of the sensor unit 1 is slid by the guidance of the groove 9, the operation causes the mark 66 of the sensor unit 1 to be fitted to the bar mark of any one of the marks 64, or the number of any one of the marks 65.値 Location. The purpose of this operation will be described later. The processing sequence of this embodiment will be described in accordance with the flowchart of Fig. 10. The program according to the flowchart and the data referred to when the program is executed are stored in the ROM 21 or the RAM 22 in advance, and the CPU 20 executes the processing while referring to the data and reading the program. Further, it is assumed here that the display unit 3 is supplied with power to be in an operable state. First, the user turns ON the power switch (not shown) of the operation unit 23. In response to the ON operation, the CPU 20 instructs the control circuit 17 via the communication circuit 18 to switch the switching valve 16 to the negative pressure pump 15 side to drive the negative pressure pump 15 (step S1). Therefore, the control circuit 17 switches the switching valve 16 to drive the 200812545 dynamic negative pressure pump 15 in accordance with the instruction. When the negative pressure pump 15 is driven, the wristband pressure is transmitted through the switching valve 16 at a pressure lower than atmospheric pressure, so that the pressure sensor array 11 is moved in the upward arrow direction by the arrow 25 of Fig. 6(C). As a result, the pressure sensor array 11 can be prevented from being accidentally protruded to cause an erroneous action or malfunction. Thereafter, when the measurer wears the sensor unit 1 on the wrist as shown in FIG. 4 and turns on the start switch 23C of the operation unit 23, the control circuit 17 determines the pressure sensor array 1 with the instruction signal from the CPU 20. 1 Whether to move, that is, whether the sensor unit 1 has been slid along the sliding groove 9 to a position on the surface of the wrist (S2). A micro switch (not shown) for detecting slip is provided in the casing 1 of the sensor unit 1, and the control circuit 17 determines whether or not the pressure sensor array 1 1 is moved based on the detection signal of the micro switch. . When the movement is not determined (NO in step S2), the processing in step S1 is repeated. On the other hand, when it is determined that there is movement (YES in step S2), the control circuit determines whether or not the switch 23C is operated based on the operation signal given from the operation unit 23 (step S2a). If the result of the determination is that the switch 23C is not operated, that is, when the measurement is not instructed to start (NO in step S2a), the process returns to step S1, and thereafter, the process of steps S1 and S2 is repeated until the switch 23C is operated. . On the other hand, when the result of the determination in step S2a is that the switch 23C is operated, that is, when the measurement has been instructed to be turned on (YES in step S2a), the control circuit 17 switches the switching valve 16 to the side of the pressurizing pump 14 to The pressurizing pump 14 is driven (step S3). Accordingly, the pressure of the wristband is increased, and the pressure sensor array 11 is moved in the direction of the arrow below the arrow 25 of FIG. 6(C), and the pressure sensor array 11 is pushed against the surface of the wrist -19-200812545. . When the pressure sensor array 11 is pushed against the wrist surface (refer to FIG. 7), the pressure information of the voltage signal (information of the pulse pressure) is controlled by the respective pressure sensors 26 by the multiplexer 12. The data is converted to digital information by the A/D converter 19, and is supplied to the tone map creation unit 204 of the display unit 3 by the communication circuit 18. At this time, from the pressure sensor 26 at one end of the pressure sensor array 1 1 to the pressure sensor 26 at the other end, the pressure information is given to the tone map creation portion 204 in the order of its position. . Tone map creation Φ section 204 creates a tone map using the given digital information (pressure information), and outputs the created tone map data 301 to the memory control unit 203 (S3a). The memory control unit 203 stores the given data in the RAM 22. At this time, the switching unit 205 determines whether or not the display of the tone map is switched in any one of the operator's viewpoint and the patient's viewpoint based on the switching operation signal input from the operation unit 23 (step S4). Here, it is assumed in advance that the switch 23A or 23B is operated by the patient or the operator. Therefore, for example, when the switch 23A is operated in advance, the switching unit 205 instructs the display control unit 202 to display the tone map used for the patient viewpoint based on the switching operation signal input by the operation, but when the switch 23 B is operated in advance, The display control unit 202 is instructed to display the first map used by the operator's viewpoint based on the switching operation signal input by the operation. The display control unit 202 reads the tone map data 301 from the RAM 22, and displays the tone map on the display 24 in accordance with the instruction given from the switching unit 205 based on the read data (steps S5 and S6). Here, the display form of the tone map, -20- . 200812545 is changed according to the instruction given by the switching unit 205. The tone maps that are created and displayed will be described later. Next, the pulse wave processing unit 206 performs processing of the solid matter other than the 腱29 in accordance with the tone map (step S7)'. In the processing of the solid matter exclusion, it is specified based on the tone map information obtained at S3a. The pressure sensor 26 in the pressure sensor array 11 is located on the solid object, and the remaining pressure sensor 26, except for the specific pressure sensor 26, is candidately selected to be located in the radial artery 27 Pressure sensor 26 on. 9 Next, the pulse wave processing unit 206 performs a process of selecting the pressure sensor 26 located on the curved bone artery 27 as the optimal channel from the candidates of the pressure sensor 26 located on the radial artery 27 (step S8). . The details of this optimum channel selection process are described in detail in Japanese Patent Laid-Open Publication No. 2004-222847, the entire disclosure of which is hereby incorporated herein. The tone map data 3 01 is for each of the pressure sensors 26 and includes data of a DC component and an AC component represented by a pulse pressure signal detected by the pressure sensor 26. The CPU 20 is configured to have a DC component level of a certain threshold or more. The pressure sensor 26 is specifically positioned not on the radial artery 27. The CPU 20 then treats the remaining pressure sensor 26, except for the particular pressure sensor 26, as a candidate for a pressure sensor located on the radial artery 27. Then, from this candidate, the level of the DC component is lower, and the pressure sensor 26 having a higher level of the AC component is selected as the optimum channel. Next, the pulse wave processing unit 206 detects the pulse wave based on the pressure information input from the pressure sensor 26 corresponding to the selected optimal channel, and therefore calculates the fluctuation amount based on the pressing level of the pressing wrist band 13 . Then, the calculated fluctuation amount is compared with the predetermined fluctuation amount of the detectable pulse wave of -21 to 200812545 (step S9). As a result of the comparison, if the calculated fluctuation amount satisfies the predetermined fluctuation amount, it is determined that the wristband pressure condition for pulse wave detection is satisfied (YES in step S10), and if it is not satisfied, the control circuit 17 is used to pass the pressure pump. 1 4 While continuing to pressurize the wristband 1 3, repeat the processing of steps S3a to S 10 until the wristband pressure condition is satisfied. When the wristband pressure condition is satisfied (YES in step S1 0), the pressure pump 14 is adjusted so that the pressing position of the pressure wristband 13 against the pressure sensor array 1 1 can be the most used for pulse wave detection. Good level (step S11). The details of this adjustment are described in Japanese Laid-Open Patent Publication No. 2004-222847, the entire disclosure of which is hereby incorporated by reference. Under the optimal pressure adjustment for pushing the wristband 13, the pressure information output by the pressure sensor 26 selected as the optimal channel, that is, the waveform data of the 27-pulse wave of the radial artery, is multiplexed. The device 12, the A/D converter 19, and the communication circuit 18 are transferred to the pulse wave processing unit 206 (step S12). The pulse wave processing unit 206 receives the waveform data and performs pulse wave detection based on the received waveform data. The pulse wave data transfer processing of step S 1 2 is repeated before the waveform data is accepted and the predetermined condition for ending the pulse wave detection is established. Further, the pulse wave detecting processing based on the received waveform data is in a known order, and the details thereof are omitted here. When the predetermined condition of the end of the pulse wave detection is satisfied (YES in step S13), the CPU 20 drives the negative pressure pump 15 to control by the switching valve 16 (step S14). Thereby, the pressing state of the pressure sensor array 11 against the wrist is released, and a series of pulse wave detecting processing ends. The pulse wave processing unit 206 outputs information for detecting the pulse wave to the memory control unit -22-200812545. The memory control unit 203 stores the given information as the pulse wave information 302 in the RAM 22. The display control unit 202 reads the pulse wave information 302 from the RAM 22, and outputs the read pulse wave information 302 to the outside via the display 24. Further, the information of the pulse wave is used to calculate the AI (Augmentation Index) by the pulse wave processing unit 206, and the calculated AI can be output to the display 24. Here, a tone map created (displayed) in step S3a and step S5 (S6) will be described. • Fig. 1 is a diagram showing the arrangement of the pressure sensors 26 of the pressure sensor array 1 in accordance with an example of the display of the tone map data 301. Fig. 12 shows the state of pulse wave measurement. In the second embodiment, the measurement site of the patient collides with the pressing surface 40 of the sensor unit 1 in the pressed state, and the sensor 26 of the pressure sensor array 11 is arranged with the pressing surface 40 interposed therebetween. The direction of the patient is the one on the side of the plane (in the imaginary plane, not shown) that is substantially orthogonal (crossing) to the radial artery 27, and the other side has the viewpoint of the operator. That is, the operator is as shown in Fig. 2, assuming that the ® is in a position opposite to the patient. Referring to FIG. 1, the tone map data 30 generated by the tone map creation unit 204, the pressure sensor 26 of the pressure sensor array 11 and the pulse pressure signal output by the pressure sensor 26 are respectively referred to. To grant information to the relevant parties. The display control unit 202 reads the tone map data 301 from the RAM 22, and displays a graph as shown in Fig. 1 based on the read data. The graph takes the pulse pressure level as the vertical axis V J , and the arrangement of the pressure sensors 26 corresponds to the horizontal axis HJ. Then, the origin 0 is taken as the starting point of the graph, and the pressure sensors 2 are arranged in the order from the pressure sensor 26 on the A side to the pressure sensor 26 on the B side -23 - 200812545. 6 lif out the pulse pressure signal refers to the level of continuous plotting. Therefore, with respect to the horizontal axis ,, there is a ‘Α’ character CH on the origin 0 side, and a ‘Β’ character CH attached to the opposite side of the origin 〇 is displayed for correlation. The letter CH is the same as the mark 6 1 printed on the frame 100. Thus, the patient or operator becomes the starting point or end point that can be attached to the corresponding plot, aligned with the pressure sensor array 1 1 . The output of one of the square ends and the other end of the pressure sensor 26. The tone map of Fig. 11 indicates an example of display when the indication given from the switching unit 205 refers to the patient's viewpoint. Further, when the instruction given from the switching unit 205 refers to the operator's viewpoint, the tone map of the first map is the starting point of the graph in the horizontal axis HJ direction, and the pressure is sensed from the B side. From the 26 to the pressure sensor 26 on the A side, the pulse pressure signals output by the respective pressure sensors 26 are displayed in the order of arrangement as a continuously plotted graph. In other words, the display control unit 202 displays the tone map of the first map in reverse based on the tone map data 301 read from the RAM 22. Φ is specifically the axis of the point on the tone map which has been plotted on the output level of the pressure sensor 26 located at the center of the pressure sensor array 1 1 and is orthogonal to the horizontal axis HJ. The axis MJF is the center and is a graph in which the tone map of Fig. 11 is inverted in the horizontal axis HJ direction. At this time, the horizontal axis HJ displays the word "Β" on the origin 〇 side, and the word CH on the opposite side of the origin 0 indicates "Α". Here, the text CH is used, but as long as the output of the pressure sensor 26 of the arrangement of the pressure sensor array 11 and the output of the pressure sensor 26 of the other end can be attached to the corresponding -24-200812545, the number can also be counted. Graphics, graphics, etc. to replace the text. Further, although the characters 4 A ' and ' B ' corresponding to both ends are not displayed, only the characters of one side may be displayed. Therefore, as shown in Fig. 12, when the patient performs the measurement while the display unit 3 is placed on the screen of the display 24, the patient viewpoint shown in Fig. 11 can be displayed by operating the patient switch 2 3 A. Tone map. Therefore, the patient can confirm the 'A' of the character CH displayed together with the tone map, and the A' corresponding to the display φ text ' of the mark 6 1 or 62 printed on the frame 1 00 of the sensor unit 1 . Both are on the left side of the patient, and 'B, the text is on the right side of the patient. Therefore, when the sensor unit 1 is moved while looking at the change of the tone map, it is possible to prevent an error in the movement operation direction/and an operator who is opposed to the sensor unit 1 in the patient of the second aspect in order to confirm the tone map. The operator switch 23B is operated by changing the arrangement of the display unit 3 so that the screen of the display 24 changes toward the screen. Accordingly, the tone map shown in Fig. 1 can be reversely displayed to display the tone map of the operator's viewpoint. Therefore, the operator can confirm that the word 'A' of the character CH displayed together with the tone map and the 'A' corresponding to the display text of the mark 61 or 62 printed on the frame 100 of the sensor unit 1 are They are all on the right side of the operator and can be confirmed that the text of 'B' is on the left side of the operator. Therefore, when the sensor unit 1 is moved while watching the tone map change, it is possible to prevent the error of the moving operation direction. (Dialogue display) In the present embodiment, the patient or the operator may be guided by displaying the operation sensor unit 1 in a direction in which the sensor unit 1 slides along the groove 9. In order to display the pair -25-200812545, the patient display data (a side) and side of the RAM 22 are used 3〇3 and 3 05, and the operator display data (A side) and (B side) 304 and 306 are used. Fig. 13 shows an example of a tone map for displaying an operator viewpoint and a patient viewpoint, and dialogs E1 and E2. In Fig. 13, on the tone map of the operator's viewpoint and the patient's viewpoint, in addition to the tone map, a mark 63 is displayed, which is instructed by the display control unit 202 to indicate the tone map with the operator's viewpoint and the patient's viewpoint. Any correspondence. The dialog display unit 207 reads the tone map Φ 301 through the memory control unit 203, analyzes the read tone map data 301, and determines whether or not it is the optimum tone map based on the analysis result. Here, the so-called optimal tone map is referred to as a tone map corresponding to the central position of the tone map as shown in Fig. 11 . In other words, when the pressure sensor 40 is pressed against the measurement site and the pressure sensor 26 at the center of the pressure sensor array 1 1 is located on the radial artery 27, the optimal tone map as shown in Fig. 11 It was measured. According to the tone map of Fig. 11, the distribution of the pulse pressure around the iliac artery 27 at the measurement site can be confirmed at a glance. The dialog display unit 207 determines whether or not the pressure sensor 26 indicating the peak of the tone map data 30 1 is the pressure sensor 26 located at the center of the pressure sensor array 1 1 . When it is determined that it is not at the center of the pressure sensor 26, a dialog of an error message is displayed in accordance with the display control unit 202. That is, a GUI is displayed to move the operation sensor unit 1 at a position where the best tone map can be obtained. Specifically, the dialog display unit 207 instructs the display control unit 202 to display the dialogue E1 or E2 of the operator viewpoint or the patient viewpoint in accordance with another signal operated by the switches 23A and 23B fed from the switching unit 205. The display control unit 202-26-200812545 reads out the data based on the instruction given from the RAM 22 via the memory control unit 203, and displays the dialog E1 or £2 on the display 24 based on the data read. A specific display example is shown in Fig. 14. As a specific example of the dialogue E2, Fig. 14(A) shows the operator's viewpoint' and Fig. 14(B) shows the patient's viewpoint based on the patient's viewpoint. When the optimal tone map is not determined, the pressure sensor 26 in the center of the pressure sensor array 1 is positioned on the radial artery 27 by a dialogue to guide the direction of movement of the sliding operation of the sensor unit 1. • For example, according to the dialog display unit 207, the tone map peak of the operator's viewpoint in Fig. 3 is detected as being separated from the axis M of Fig. 1; [When the bit is on the opposite side of the origin 0, the dialog display is displayed. The display unit 202 instructs the display control unit 202 to display the operator display data (B side) 306. Therefore, the display control unit 202 reads the operator display data (B side) 306 via the memory control unit 203 based on the instruction. And displayed on the display unit 24. The dialog of FIG. 14(A) is displayed in accordance with the operator's display data (B side) 306, and the sensor unit 1 is moved to the 'B' side indicated by the mark 61 or 62. The pattern is guided along with its operator ^(). Further, in the case where the tone map peak of the patient viewpoint in Fig. 1 is detected to be on the origin 〇 side across the axis M of Fig. 11, the dialog display unit 207 instructs the display control unit 2 2 The patient display data (B side) 3〇5 is displayed. Therefore, the display control unit 202 reads the patient display data (B side) 305 through the memory control unit 203 and displays it on the display 24 based on the instruction. The dialogue of FIG. 14(B) is displayed according to the patient display data (B side) 305, and the sensor unit 1 is moved to the 'B' side indicated by the mark 61 or 62. -27-200812545 The pattern of the detector unit 1 is guided together with its operation direction (->). Therefore, the operator or the patient operates the sensor unit 1 worn by the patient to know the direction of movement guided by the slot 9. Further, in the dialogue, in the circle that is emerging, the position of the alignment of the bar-shaped marks of the mark 66 and the mark 64 is used to indicate which direction should be moved. The bar-shaped mark to be displayed coincides with the bar-shaped mark colored in a different color on the frame 100 for accommodating the sensor unit 1, so that the direction to be slid can be imparted with the color of the bar-shaped mark. Fig. 15 is a view showing a dialog when the mark 65 is provided instead of the mark 64, as in the case of Fig. 13. The order of the number of marks 65 displayed (ascending or descending order) is the same as the number of marks 65 printed on the upper surface of the frame 1 00 for housing the sensor unit 1, so The direction of the slide is given to the number of marks 66. (display form of the tone map at the time of switching) The display control unit 202 may change (switch) the tone map seen from the displayed patient side (one side) viewpoint from the operator side (the other side). The state in which the shape of the tone map changes during the tone map seen from the viewpoint is displayed on the display 24. Fig. 16 is a view showing an example of switching the display of the tone map by the display control unit 202 when the switches 23A and 23B are operated. In the state in which the switch 23A is operated, in the state in which the tone map of the upper stage of FIG. 6 is displayed, when the switch 23B is operated and there is an instruction to switch to the operator's viewpoint, the display control unit 202 causes the control unit 202 to The tone map in the display is gradually rotated in the direction of the axis H from the axis MJ of Fig. 11, and the process is performed until the state of -28 - 200812545 is reversed, and the cell is shifted and simulated. The change in the chart to be displayed is shown. By shifting between the states of the graphs in the rotation, the final reversed tone map, that is, the tone map of the operator's viewpoint, is displayed. Here, the switching instruction is given to the switch 2 3 A or 23B ' of the operation display unit 3, but it may be replaced, and instead the switches 23a and 23B are provided in the sensor unit 1, and then given from the sensor unit 丨. Here, in order to give a switching instruction, two switches 23 A and 23 B are provided, but one of the switches may be, for example, each time (pressing), the operator's viewpoint/patient viewpoint switching instruction may be given. The two-way switch used. Further, it is also possible to change the direction of the display 24 in accordance with the turning operation, and to switch between the tone map of the operator's viewpoint and the tone map of the patient's viewpoint in response to the turning operation. In the above embodiment, the display unit 3 The pulse pressure information detected by the sensor unit 1 is received from the fixed station unit 7 by means of communication, but the method of acceptance is not limited thereto. In other words, the CPU 20 may acquire the pulse wave information from the CD-ROM 42^ storing the pulse pressure information detected by the sensor unit 1 by the external I/F 41.
