실제로, 게이지부압(negative gauge pressure)을 상처에 적용하는 것은 '진공을 이용한 봉합(Vacuum Assisted Closure 또는 V.A.C.®' 치료라는 명칭하에 상업화되었고, 초과삼출물(excess fluid)을 제거하는 동시에 상처를 기계적으로 위축시키는 것과 관련되어 있다. 이러한 방식으로, V.A.C.®치료는 인체의 자연적 염증반응(inflammatory process)을 증대시키면서도, 적절한 정맥환류(靜脈還流, venous return)를 위해 필요한 혈관구조가 결여되어 있는 상태에서의 혈류(血流)의 증가에 기인한 부종(浮腫, edema)의 생성과 같은 공지된 많은 내인 부작용(intrinsic side effect)을 완화시킨다. 그 결과, V.A.C.®치료는, 상처봉합의 촉진과, 이전에 치료가 매우 어려운 것으로 간주되던 많은 상처들을 치료하는데 획기적 성공을 거두었다.Indeed, the application of negative gauge pressure to wounds has been commercialized under the `` Vacuum Assisted Closure or VAC® '' treatment, which mechanically shrinks the wound while removing excess fluid. In this way, VAC® treatment enhances the body's natural inflammatory process, while lacking the vascular structure necessary for proper venous return. Alleviates many of the known intrinsic side effects, such as the production of edema due to increased flow, resulting in the promotion of wound closure and prior treatment. Has had tremendous success in treating many wounds that were considered very difficult.
하지만, 종래 기술에서는, 상처 치료기가 동작하는 과정의 힘을 이용해서 추가 동력원 없이 자동으로 약물 주입이 가능한 상처 치료기에 대해서는 개시된 바 없는 상황이다. However, in the prior art, there is no situation in which the wound healing device capable of automatically injecting drugs without additional power source by using the force of the operation of the wound healing device is disclosed.

The wound treatment device according to an embodiment of the present invention includes a seal 620, a first conduit 300, an exudate reservoir 100, a body, a pressure sensor, a component sensor, and a level sensor.
여기서, 밀봉부는 상처 조직(600) 부위를 밀봉하여 공압 펌프(P)를 통해서 공급되는 음압이 제대로 걸릴 수 있도록 하는 구성이다. 밀봉부는 통상 상처(600)의 형태에 맞게 삽입하는 폼(610)과 폼(610)을 밀봉하는 드레이프(620) 등으로 이루어진다.

The main body includes a user user interface (GUI) and a pneumatic pump, and is connected to the exudate reservoir 100 to connect the second conduit 310, the exudate reservoir (or canister) 100, and the first conduit 300. The wound treatment device is controlled to provide negative pressure to the wound tissue site. Furthermore, the site where the exudate storage part 100 is mounted may be provided on one side of the main body part. The pneumatic pump exists in the main body, and it is possible to use a pump or the like using a reciprocating motion of the diaphragm in response to the magnetic force generated by applying a current to the coil.
또한, 상처 치료기에서는, 압력센서, 성분 센서 및 레벨 센서를 포함한다. Wound care devices also include pressure sensors, component sensors, and level sensors.
여기서, 레벨 센서는, 제 1 도관부(300)를 밸브(미도시)로 막은 후, 본체부의 제어에 따라서 공압 펌프에서 삼출물 저장부(100)로 제공하는 음압을 제공했을 때, 삼출물 저장부 내부의 압력을 센싱하는 압력 센서에서 센싱되는 음압의 절대값의 기울기를 기초로 하여, 삼출물 저장부(100) 내부의 삼출물이 어느 레벨까지 가득찼는지 또는 삼출물 저장부(100) 내부에 빈 공간(잔량)이 어느 정도인지를 검출할 수 있다. Here, when the level sensor blocks the first conduit 300 with a valve (not shown) and provides a negative pressure provided by the pneumatic pump to the exudation reservoir 100 under the control of the main body portion, Based on the slope of the absolute value of the negative pressure sensed by the pressure sensor for sensing the pressure, to what level the exudate in the exudate storage unit 100 is filled up or the empty space (remaining amount) inside the exudate storage unit 100 This can be detected to what extent.
이것을 구체적으로 설명하면, 본체부의 제어에 따라서 공압 펌프에서 일정 값의 음압을 공급한다고 가정하면, 삼출물 저장부(100) 내부가 가득 차서 잔량 체적이 적을 경우 빠르게 음압의 절대값이 상승하겠지만, 삼출물 저장부(100)의 내부가 ㅂ비어있는(empty) 상태라면 잔량의 체적이 커서 상대적으로 느리게 음압의 절대값이 상승하게 된다. 따라서, 음압의 절대값의 상승 기울기를 검출함으로써, 삼출물 저장부(100) 내부의 삼출물이 어느 레벨까지 가득찼는지 또는 삼출물 저장부(100) 내부에 빈 공간(잔량)이 어느 정도인지를 검출할 수 있게 된다. 나아가, 시제품 단계에서의 테스트를 통해서, 캐니스터의 내부 잔량 체적값(V)과 공급 압력 절대값의 시간 변화율(기울기) 간에 계산식을 도출해 낼 수 있다. Specifically, assuming that the pneumatic pump supplies a predetermined value of negative pressure under the control of the main body, if the internal volume of the exudate storage unit 100 is full and the remaining volume is small, the absolute value of the negative pressure will quickly increase, but the exudate storage. If the inside of the part 100 is empty, the absolute value of the sound pressure increases relatively slowly due to a large volume of the remaining amount. Therefore, by detecting the rising slope of the absolute value of the negative pressure, to what level the exudate inside the exudate storage unit 100 is filled up or how much empty space (remaining amount) is inside the exudate storage unit 100 can be detected. It becomes possible. Furthermore, a test at the prototyping stage yields a calculation between the internal residual volume value (V) of the canister and the rate of change of time (tilt) of the absolute supply pressure.

In addition, the component sensor, the first conduit portion 300 entering the exudate storage unit 100 or the first conduit unit 300 inside the exudate storage unit is formed flat, but the transmitting unit 110 or 115 on both sides formed flat. ) And the receiver 115 or 110, and based on the signal result of the receiver corresponding to the signal application of the transmitter, the degree of blood contained in the exudate 210 or the concentration and component of the exudate may be examined.

In addition, the component sensor, the first conduit 300 existing between the transmitter and the receiver is at least partially transparent or translucent so that the receiver can receive the light transmitted from the transmitter, the wavelength of the light received at the receiver Based on the change and the change in the intensity of light, the degree to which the blood inside the exudate is contained, and the concentration or component of the exudate can be detected.
