Description
본 발명은 위생패드에 관한 것으로서, 더욱 상세하게는 기저귀 또는 생리대 등의 위생패드에 시약 인쇄 기술을 적용하여 pH 측정 수치를 시각적으로 확인이 가능한 위생패드 구조에 관한 것이다.The present invention relates to a sanitary pad, and more specifically, to a sanitary pad structure in which a pH measurement value can be visually confirmed by applying a reagent printing technology to a sanitary pad such as a diaper or sanitary pad.
일반적으로, 수분흡수 기능을 갖는 위생패드, 예를 들면, 기저귀, 여성용 생리대, 요실금 팬티 등은 내부에 수분 흡수 기능이 뛰어난 내부 흡수층이 구비되고, 사용자의 피부와 인접하는 외측에는 흡수성이 높은 친수성 직물이 감싸는 형태의 구조를 이루게 된다.In general, sanitary pads with moisture absorption functions, such as diapers, feminine hygiene pads, and incontinence panties, have an inner absorbent layer with excellent moisture absorption functions, and the outer side adjacent to the user's skin is wrapped with a highly absorbent hydrophilic fabric.
한편, 종래 위생패드는 단순히 소변 또는 생리혈을 흡수하는 용도로만 활용이 이루어지는데, 유아의 경우 육안으로는 소변을 보았는지 여부를 신속하게 확인이 어려운 불편이 있었다.Meanwhile, conventional sanitary pads are simply used to absorb urine or menstrual blood, but in the case of infants, it was inconvenient to quickly check with the naked eye whether or not they had urinated.
또한, 최근에는 건강에 대한 관심이 높아지는 시점에서 이러한 소변이나 생리혈 등과 같은 인체 분비물을 활용하여 건강상태를 확인할 수 있는 기능이 요구되는 실정이다.In addition, as interest in health has increased in recent years, there is a demand for a function that can check health status using human secretions such as urine or menstrual blood.
본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 위생패드의 내측에 pH측정수단을 적용하여 색상 변화를 이용한 개인의 식습관 개선 및 질병의 예측이 이루어질 수 있도록 하는데 목적이 있다.The present invention has been proposed to improve the problems in the above-mentioned prior art, and has the purpose of enabling improvement of an individual's eating habits and prediction of diseases by using color changes by applying a pH measuring means to the inside of a sanitary pad.
상기 목적을 이루기 위한 본 발명은, 인체의 피부면에 접촉 사용이 이루어지는 위생패드에 있어서, 상기 위생패드는 내부 흡수층과 외부커버층으로 구성되되, 상기 외부커버층과 내부 흡수층 사이에는 외부커버층을 통해 외부로부터 스며든 인체 분비물과 접촉시 pH 수치에 따른 색상이 발현되는 pH측정수단이 구비된 것을 특징으로 한다.In order to achieve the above object, the present invention relates to a sanitary pad that is used in contact with the skin surface of a human body, wherein the sanitary pad comprises an inner absorbent layer and an outer cover layer, and is characterized in that a pH measuring means is provided between the outer cover layer and the inner absorbent layer, which displays a color according to the pH level when in contact with human secretions that have seeped in from the outside through the outer cover layer.
또한, 상기 pH측정수단은 리트머스 시약이 외부커버층의 내측면에 인쇄된 것임을 특징으로 한다.In addition, the pH measuring means is characterized in that the litmus reagent is printed on the inner surface of the outer cover layer.
이러한 본 발명의 위생패드는, 기저귀 또는 생리대 등과 같은 패드 사용 후 나타나는 pH 수치에 따른 색상 변화를 시각적으로 확인하여 개인의 식습관을 균형있게 유지하는데 도움을 줄 수 있게 됨과 함께 질병 예측에 따른 건강이 악화되는 것을 미연에 방지하는 효과를 나타낸다.The sanitary pad of the present invention can help maintain a balanced eating habit by visually confirming the color change according to the pH level that appears after using a pad such as a diaper or sanitary pad, and also has the effect of preventing the deterioration of health according to disease prediction in advance.

이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the attached drawings.
본 발명의 실시 예는 여러 가지 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상세히 설명하는 실시 예로 한정되는 것으로 해석되어서는 안 된다. 본 실시 예는 당 업계에서 평균적인 지식을 가진 자에게 본 발명을 더욱 완전하게 설명하기 위하여 제공되는 것이다.The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to more completely explain the present invention to a person having average knowledge in the art.
따라서, 도면에서 표현한 구성요소의 형상 등은 더욱 명확한 설명을 강조하기 위해서 과장되어 표현될 수 있다. 각 도면에서 동일한 구성은 동일한 참조부호로 도시한 경우가 있음을 유의하여야 한다. 또한, 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 공지 기술의 기능 및 구성에 관한 상세한 설명은 생략될 수 있다.Accordingly, the shapes of components, etc., depicted in the drawings may be exaggerated in order to emphasize a clearer description. It should be noted that in each drawing, the same components are sometimes depicted with the same reference numerals. In addition, detailed descriptions of functions and configurations of known technologies that are judged to unnecessarily obscure the gist of the present invention may be omitted.
먼저, 본 발명의 일 실시 예에 따른 위생패드 생리대의 구조를 도 1 내지 도 3을 통해 살펴보면 다음과 같다.First, the structure of a sanitary pad according to an embodiment of the present invention is as follows with reference to FIGS. 1 to 3.
본 실시 예에서의 위생패드 생리대는, 외측 커버를 이루는 박막의 외부 커버층(10) 내부에 내부 흡수층(20)이 구비되고, 상기 외부커버층(10)과 내부 흡수층(20) 사이에는 외부커버층(10)을 통해 외부로부터 스며든 인체 분비물과 접촉시 pH수치에 따른 색상이 발현되는 pH측정수단(30)이 구비된다.In the sanitary pad of the present embodiment, an inner absorbent layer (20) is provided inside an outer cover layer (10) of a thin film forming an outer cover, and a pH measuring means (30) is provided between the outer cover layer (10) and the inner absorbent layer (20) that displays a color according to the pH level when in contact with body secretions that have seeped in from the outside through the outer cover layer (10).
이때, pH측정수단(30)은 리트머스 시약이 외부커버층의 내측면에 인쇄된 인쇄층으로 이루어지게 된다.At this time, the pH measuring means (30) is formed by a printed layer in which litmus reagent is printed on the inner surface of the outer cover layer.
한편, 본 실시 예에서의 리트머스 시약은 리트머스 용액에 인쇄품질 향상을 위한 요소수지 및 소듐바이카보네이트 성분이 혼합된 조성물을 사용함이 바람직하며, 이때에는 리트머스 용액 70~90중량%, 요소수지 1~10중량%, 소듐바이카보네이트 1~10중량%, 벤질아크릴레이트 1~10중량%, 폴리에틸렌왁스 1~5중량%의 비율로 혼합된 리트머스 시약이 사용될 수 있다.Meanwhile, in the present embodiment, it is preferable to use a composition in which a litmus reagent is a litmus solution mixed with a urea resin and sodium bicarbonate components for improving printing quality. In this case, a litmus reagent mixed in a ratio of 70 to 90 wt% of litmus solution, 1 to 10 wt% of urea resin, 1 to 10 wt% of sodium bicarbonate, 1 to 10 wt% of benzyl acrylate, and 1 to 5 wt% of polyethylene wax can be used.
또한, 리트머스 시약의 변질 방지를 위한 싸이오황산소듐 및 아염소산이 각각 1~5중량% 추가로 첨가됨이 바람직하다.Additionally, it is preferable to additionally add 1 to 5 wt% of sodium thiosulfate and chlorous acid to prevent deterioration of the litmus reagent.
본 실시 예에서의 외부커버층(10)은 외부에서 내부 리트머스 인쇄층의 색상발현 확인이 용이하게 이루어질 수 있는 부직포 등과 같은 박막 재료가 사용될 수 있다.In the present embodiment, the outer cover layer (10) may be made of a thin film material such as a non-woven fabric, which allows easy confirmation of the color expression of the inner litmus printing layer from the outside.
이와 같은 구성을 이루는 본 발명 위생패드 생리대의 사용에 따른 작용효과를 살펴보기로 한다.Let us examine the effects of using the sanitary pad of the present invention having such a configuration.
본 발명의 pH측정수단(30)인 리트머스 시약이 내측에 인쇄된 상태에서 생리대의 착용이 이루어지게 되면, 생리혈이 외부커버층(10)을 통해 스며들어 내부 흡수층(20)에 흡수되는 과정에서 리트머스 인쇄층에 접촉이 이루어짐에 따른 색상이 발현될 수 있게 된다.When the sanitary pad is worn with the litmus reagent, which is the pH measuring means (30) of the present invention, printed on the inside, color may be expressed as menstrual blood seeps through the outer cover layer (10) and comes into contact with the litmus printing layer in the process of being absorbed into the inner absorbent layer (20).
즉, 리트머스 시약은 pH가 4~8 수치인 경우에는 정상으로 나타나는 가운데 pH4 이하인 산성인 경우는 pH측정수단(30)이 붉은색을 나타내고, pH8 이상인 염기성인 경우는 녹색으로 나타내어지게 된다.That is, the litmus reagent appears normal when the pH is between 4 and 8, and when the pH is acidic (less than pH 4), the pH measuring means (30) appears red, and when the pH is alkaline (more than pH 8), it appears green.
이와 같이 산성으로 pH 색상 발현이 이루어지는 경우 고기류를 과다 섭취하거나 전염병이 있는 것으로 판단이 이루어질 수 있고, 염기성으로 색상 발현이 이루어지는 경우는 채식 위주, 신장병, 자궁암, 유방암, 당뇨 등의 질병이 있는 경우에 해당될 수 있다.In this way, if the pH color expression is acidic, it can be judged as excessive consumption of meat or the presence of an infectious disease, and if the color expression is alkaline, it can be judged as a case of mainly vegetarian diet, kidney disease, uterine cancer, breast cancer, diabetes, etc.
이와 같이 시각적인 pH측정치의 확인이 이루어지면, 이를 바탕으로 자신의 식습관을 보다 균형있게 조절하는데 도움을 줄 수 있게 되며, 질병이 의심되는 경우에는 신속하게 병의원의 내방이 이루어질 수 있게 된다.When the visual pH measurement value is confirmed in this way, it can help you to adjust your eating habits to be more balanced, and if you suspect a disease, you can quickly visit a hospital.
특히, 본 발명에서의 리트머스 시약은 리트머스 원액 외에도 요소수지 및 소듐바이카보네이트이 혼합되어 있기 때문에 외부커버층(10)과 인쇄층의 접착 인쇄상태가 안정적으로 유지됨과 함께 탈락 현상이 방지될 수 있으며, 벤질아크릴레이트 및 폴리에틸렌왁스는 시약의 점도 조절이 이루어질 수 있게 되어 인쇄 과정에서 리트머스 시약이 외부커버층(10)에 과다하게 흡수되는 것을 방지함에 따른 적절한 두께의 인쇄층 형성에 도움을 줄 수 있게 된다.In particular, since the litmus reagent of the present invention is a mixture of urea resin and sodium bicarbonate in addition to the original litmus solution, the adhesive printing state of the outer cover layer (10) and the printing layer can be stably maintained while the peeling phenomenon can be prevented, and since the viscosity of the reagent can be adjusted by benzyl acrylate and polyethylene wax, it can help form a printing layer of an appropriate thickness by preventing the litmus reagent from being excessively absorbed into the outer cover layer (10) during the printing process.
또한, 추가 첨가된 싸이오황산소듐 및 아염소산은 각각 리트머스 용액의 변질 발생을 방지함과 함께 색상 구현이 보다 선명하게 나타내어지는 이점을 나타내게 된다.In addition, the additionally added sodium thiosulfate and chlorous acid have the advantage of preventing deterioration of the litmus solution and making the color more vivid.
따라서 본 발명의 위생패드는, 기저귀 또는 생리대 등과 같은 패드 사용 후 나타나는 pH 수치에 따른 색상 변화를 시각적으로 확인하여 개인의 식습관을 균형있게 유지하는데 도움을 줄 수 있게 됨과 함께 질병 예측에 따른 건강이 악화되는 것을 미연에 방지하는 효과를 나타낸다.Therefore, the sanitary pad of the present invention can help maintain a balanced eating habit by visually confirming the color change according to the pH level that appears after using a pad such as a diaper or sanitary pad, and also has the effect of preventing the deterioration of health in advance according to disease prediction.
그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 위생패드 구조가 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다. And, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the sanitary pad structure of the present invention can be implemented in various ways by those skilled in the art.
예를 들면, 상기 실시 예에서는 본 발명이 생리대에 적용된 형태가 설명 및 도시되었으나, 본 발명의 pH 측정 기술은 유아용 기저귀, 성인용 요실금 팬티 등과 같은 다양한 형태의 위생패드에 적용될 수 있게 된다.For example, although the above embodiment has described and illustrated a form in which the present invention is applied to a sanitary pad, the pH measurement technique of the present invention can be applied to various forms of sanitary pads, such as infant diapers, adult incontinence panties, etc.
