Description
본 발명은 환자의 체내(體內)에 수액을 투여할 때 발생 할 수 있는 혈액(血液)의 역류(逆流)현상을 방지하기 위한 역류방지용 수액셋트 역류방지용 장치에 관한 것이다. 일반적으로 수액셋트는 환자에게 수액이나 혈액제등을 공급하기 위하여 수액팩/링거병(1)에 삽입되는 삽입봉(2)과, 수액의 투여 상태를 확인하기 위한 확인창(3), 공급관(4)을 통해 공급되는 수액량을 조절하기위한 조절부(5)와, 카테터부(6)로 구성된 것으로 환자의 체내에 수액을 투여하기 위해 사용되는 의료기기이다. 그러나 이러한 수액셋트는 수액팩/링거병(1)의 수액이 환자의 체내로 완전히 투여되고 남아있지 않게되거나, 수액팩/링거병(1)이 카테터부(6) 부위보다 낮은 상태가 되면 환자의 정맥 혈압(血壓)이 수액팩/링거병(1)의 압력보다 높아져서 환자의 혈액이 수액셋트를 따라 역류하는 현상이 발생하여 환자의 건강을 위협한다. 그러므로 이러한 역류현상을 방지하기 위하여 보호자나 간호사등이 링거병내의 남아있는 수액량을 수시로 확인하는 번거로움과 불편함이 발생하게 되었다.The present invention relates to an infusion prevention device for preventing backflow for preventing the backflow of blood, which may occur when administering an infusion to a patient's body. In general, the infusion set includes an insertion rod (2) inserted into the sap pack / ringer bottle (1) for supplying a sap or blood to a patient, a confirmation window (3) for checking the administration state of the sap, and a supply pipe ( It is composed of a control part 5 for adjusting the amount of fluid supplied through 4) and the catheter part 6, and is a medical device used for administering fluid in the body of a patient. However, such an infusion set does not remain when the sap pack / ringer bottle (1) is completely administered and remains in the patient's body, or when the sap pack / ringer bottle (1) is lower than the catheter portion (6). Intravenous blood pressure (血壓) is higher than the pressure of the sap pack / Ringer's disease (1), the blood flow of the patient along the infusion set occurs, threatening the patient's health. Therefore, in order to prevent such a reflux phenomenon, the hassle and inconvenience that the guardian or nurse often checks the amount of fluid remaining in Ringer's disease occurs.
본 발명은 종래의 수액셋트 사용시 도래할 수 있는 혈액의 역류현상을 방지하도록 수액세트의 일단에 장착되어 수액팩/링거병(1)의 수압이 환자의 정맥내의 압력보다 낮을 때 발생하는 혈액의 역류현상을 제어하여, 환자를 보호하며 보호자나 간호사가 겪는 불편함을 해소할 수 있도록 고안된 수액셋트 역류방지 장치이다.The present invention is mounted on one end of the infusion set to prevent the backflow of blood that can come when using the conventional infusion set, the blood flow back when the water pressure of the infusion pack / ringer bottle (1) is lower than the intravenous pressure of the patient It is a fluid set backflow prevention device designed to control the phenomena, to protect the patient and to solve the discomforts of the guardian or the nurse.
본 발명의 구성을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The configuration of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 구성을 보이기 위한 전체 단면도로서, 본 발명 수액셋트 역류방지 장치는 수액팩/링거병(1)에 삽입하여 수액이나 혈액제등을 공급받기 위한 삽입봉(2)과, 수액의 투여상태를 확인하기 위한 확인구(3)와, 상기 확인구(3)와 연결된 공급관(4)을 통해 공급되는 수액량을 조절하기위한 조절부(5)와, 환자의 체내로 수액을 투여(投與)하기 위한 카테터부(6)로 구성된 공지의 수액셋트에 있어서, 상기 카테터부(6) 근위의 공급관(4)에 탄성막(10)이 부착된 본체(20)로 구성 되어진다.1 is an overall cross-sectional view for showing the configuration of the present invention, the present invention fluid set backflow prevention device is inserted into the sap pack / ringer bottle (1) inserted rod (2) for receiving the fluid or blood, and the sap Confirmation port (3) for confirming the administration state of the control unit, and the control unit (5) for adjusting the amount of fluid supplied through the supply pipe (4) connected to the confirmation port (3), and administering the fluid into the patient's body ( In the well-known infusion set comprised of the catheter part 6 for violating, it consists of the main body 20 with which the elastic membrane 10 was attached to the supply pipe 4 proximal to the said catheter part 6.
상기 탄성막(10)은 탄성적(elastic)인 막(membrane)으로, 도 2에 도시한 바와 같이 쐐기형의 구조를 이루며 두꺼운 탄성막 기시부(11)에 형성된 탄성막 일자홈(14)은 본체면(21)의 일측에 마련된 고정홈(24)과 더불어 고정돌기(40)로 고정되어 탄성막(10)이 본체공(22)을 감싸며 본체면(21)에 밀착되어 고정된다. The elastic membrane 10 is an elastic membrane (membrane), as shown in Figure 2 formed a wedge-shaped structure and the elastic membrane straight groove 14 formed in the thick elastic membrane starting portion 11 is the main body In addition to the fixing groove 24 provided on one side of the surface 21 is fixed with a fixing protrusion 40, the elastic membrane 10 wraps around the body hole 22 and is fixed in close contact with the body surface 21.
도 3에 도시한 (A)는 조절부(5)를 잠근 상태나 혹은 환자의 혈압과 카테터부(6)로부터 수액팩/링거병(1) 사이의 압력이 평형을 이룬 상태로써 탄성막(10)이 본체공(22)을 완전히 감싸며 본체면(21)에 밀착하여 수액의 흐름이 정지된 상태이며, (B)는 조절부(5)를 개방할 시 수액이 탄성막(10)의 가장 유연한 탄성막 말단부(12)를 밀며 본체면(21)과 탄성막 말단부(12) 사이를 통하여 본체실(26)로 빠져나가는 상태이며, (C)는 환자의 혈압이 수액팩/링거병(1)의 압력을 상회할 때 역류하려는 본체실(26)로부터 카테터부(6) 및 환자의 혈액은 양쪽 압력이 평행을 이룬 순간에 복원하려는 탄성력에 의하여 탄성막(10)은 이미 닫혀서 본체실(26) 이하의 수액이나 환자의 혈액은 전혀 역류할 수 없다.(A) shown in FIG. 3 is a state in which the control part 5 is locked, or the pressure between the patient's blood pressure and the fluid pack / ringer bottle 1 from the catheter part 6 is in equilibrium with the elastic membrane 10. ) Completely surrounds the body hole 22 and closes to the body surface 21 to stop the flow of the sap. (B) shows that the sap is most flexible of the elastic membrane 10 when the adjusting part 5 is opened. Pushing the elastic membrane end portion 12 and exiting the main body chamber 26 between the body surface 21 and the elastic membrane end portion 12, (C) the patient's blood pressure is in the sap pack / ringer bottle (1) The elastic membrane 10 is already closed by the elastic force to restore the catheter portion 6 and the blood of the patient from the main body chamber 26 to flow back when the pressure exceeds the pressure of the body chamber 26. The following fluids and the blood of the patient cannot flow back at all.
본 발명은 공지의 수액셋트의 구성 중 카테터부(6) 근위의 공급관(4)에 탄성막(10)이 부착된 본체(20)를 설치하여, 수액팩/링거병(1)의 내압과 환자의 정맥 혈압 차이에 의한 혈액의 역류현상을 미연에 방지하여, 혈전의 형성으로 인한 카테터의 기능손실 혹은 공기나 혈전의 정맥내로의 투입으로 인한 응급상황 방지, 또한 보호자나 간호사의 번거로운 수액량 수시로 확인을 해소할 수 있는 유용한 장치이다.The present invention is to install the main body 20 with the elastic membrane 10 attached to the supply pipe (4) proximal to the catheter portion 6 of the configuration of the known fluid set, the internal pressure of the infusion pack / ringer bottle (1) and the patient It prevents blood regurgitation due to the difference of venous blood pressure, prevents the catheter's loss of function due to the formation of blood clots or the emergency caused by the infusion of air or blood clot into the vein. It is a useful device to solve.
