Claims (9)
- 負圧によって創傷を治療するための器具であって、創傷カバー(1)と、前記負圧を選択された圧力レベルで前記創傷に提供するための第一のポンプ(9)と、キャニスタ(6)と、前記創傷カバーと前記キャニスタとの間の第一の管路(8)であって、前記第一の管路(8)は前記器具の使用中に前記創傷を前記キャニスタ(6)に接続するように配置されている第一の管路(8)と、前記キャニスタ内の圧力を計測するための第一の手段と、前記キャニスタを前記第一のポンプに接続する第二の管路(10)と、を含み、
循環ポンプ(12)が配置されて、気体体積を断続的に前記キャニスタ(6)から前記創傷部に第三の管路(13)を介して輸送して、前記キャニスタに前記第一の管路(8)を介して戻し、これにより、生じ得る滲出物を前記第一の管路から前記キャニスタに押し出し、
第二の手段が配置されて、前記キャニスタ内の前記圧力の、時間に伴う圧力曲線を分析し、前記圧力曲線が前記気体体積の前記輸送に断続的に影響され、及び
第三の手段が配置されて、前記圧力曲線が通常の循環形状とは異なっている際には、可視的及び/又は可聴的なアラームによって表示する
ことを特徴とする器具。 - 前記循環ポンプ(12)は時間制御され、及び
前記循環ポンプは、前記気体体積を一定間隔で輸送するように配置されている
ことを特徴とする請求項1に記載の器具。 - 前記循環ポンプ(12)が、前記負圧を前記気体体積の直近の循環サイクルの前と同じレベルに再確立するために必要とされる時間(t2〜t3)によって制御されることを特徴とする請求項1に記載の器具。
- 前記第二の手段はプリント回路基板(29)を含んでいることを特徴とする請求項1〜3のいずれか一項に記載の器具。
- 前記第三の手段は、ディスプレイを有するヒューマン・マシーン・インタフェイス(31)を含んでいることを特徴とする請求項4に記載の器具。
- 前記プリント回路基板(29)は、前記第一の管路が塞がれた際に前記ディスプレイ上に表示するように前記ディスプレイを制御するために配置されており、前記表示を記号の形とするか、又は明瞭な文字列とすることができることを特徴とする請求項4又は5に記載の器具。
- 逆止弁(14)が、前記創傷カバー(1)の接続ブランチ(4)内に配置され、これにより、前記循環ポンプ(12)によって圧送された前記気体体積が前記創傷に達することを妨げることを特徴とする請求項1〜6のいずれか一項に記載の器具。
- 前記キャニスタ内の前記圧力を計測するための前記第一の手段は圧力センサ(11)であることを特徴とする請求項1〜7のいずれか一項に記載の器具。
- 前記圧力センサ(11)は圧電式センサであることを特徴とする請求項8に記載の器具。
