Abstract

The present invention relates to a safety device for intravenous injection, wherein one side of a drip tube extended into a drip chamber is recessed to form an IV solution storing portion capable of storing a fixed amount of an IV solution at all time, which blocks the internal pressure of an IV container and the blood pressure in a patient′s body, thereby preventing the backflow of blood and the inflow of air. In particular, an intravenous solution set consists of an IV container, a spike for receiving an IV solution, a drip chamber formed below the spike and installed so as to allow the IV solution to be monitored, a connection tube connected to the drip chamber to draw out the IV solution, a flow regulator regulating the IV solution supplied via the connection tube, and an IV solution needle connected to the flow regulator and injected into a blood vessel in the human body to introduce the IV solution therein, wherein one side of the drip tube extending into the drip chamber of the IV solution set is recessed so as to form an IV solution storing portion capable of storing a fixed amount of the IV solution at all time, so as to block the internal pressure of the IV container and the blood pressure in a patient′s body, thereby preventing the backflow of blood and the inflow of air.

Description

링거투여 안전장치 {The safety equipment of injection of Ringer}The safety equipment of injection of Ringer

본 발명은 링거투여 안전장치에 관한 것으로서, 보다 상세하게는 점적통 내의 점적관에 오목한 형상을 만들어 항상 일정량의 수액을 저장하는 수액 저장부를 만들어 수액용기의 내압과 환자의 체내 혈압을 차단하여 혈액의 역류와 공기의 유입을 방지 할수 있는 링거투여 안전장치에 관한 것이다.The present invention relates to a ringer administration safety device, and more specifically, by creating a concave shape in a drip tube in a drip container to always create a fluid storage unit for storing a certain amount of fluid, blocking the internal pressure of the fluid container and the blood pressure in the patient's body to remove blood. The present invention relates to a ringer administration safety device capable of preventing backflow and inflow of air.

일반적인 수액세트는, 수액이 충전된 수액용기(10)와, 도입침(20)을 통해 상기 수액용기(10)로 부터 수액이 흘러나오는 점적관(30)과, 수액이 떨어지는 상태를 확인 할수 있도록 한 점적통(40)과, 상기 점적통(40)에 연결되는 연결관(50)과, 수액의 양을 조절하는 유량 조절기(60)와, 환자의 혈관에 주사되는 수액침(70)등을 포함한다.The general infusion set includes a sap container 10 filled with sap, a drip tube 30 through which sap flows from the sap container 10 through the introduction needle 20, and a state in which sap is falling. One drop container 40, a connection pipe 50 connected to the drop container 40, a flow rate controller 60 for controlling the amount of fluid, and a fluid needle 70 injected into a blood vessel of a patient Includes.

상기 수액용기(10)의 수액 잔량이나 점적통(40) 내의 수액 상태를 확인하여 상기 수액용기(10)를 교체하거나 수액 투여를 종료하게 된다. 따라서 수액투여가 종료되면, 즉시 수액침(70)을 혈관으로 부터 제거해야 하는데, 이 시기를 놓치게 되면 공기가 혈관 속으로 유입되거나, 압력 차이에 의해 혈액이 연결관(50)을 타고 역류하는 현상이 발생한다. 이러한 문제점을 해결하고자 수액세트의 혈액 역류나 공기유입을 방지하기 위한 방법과 장치들이 여러 종류가 알려져 있는데 일예로 대한민국 등록특허 제 20-0429641의 "역류를 방지하기 위한 수액세트"를 살펴보면 수액 공급호스의 일측에 형성하되 투여되는 수액의 일정량이 항상 저장 될수 있도록 “∪”형상을 갖는 수액저장부와, 수액 저장부의 일측에 연결되어 저장된 수액이 하부 방향으로 배출 될수 있도록 “∩”형상을 갖는 수액 배출부로 구성 되어진 것이다.By checking the remaining amount of the fluid in the fluid container 10 or the state of the fluid in the drip container 40, the fluid container 10 is replaced or the fluid administration is terminated. Therefore, when the fluid administration is completed, the fluid needle 70 must be immediately removed from the blood vessel. If this period is missed, air flows into the blood vessel or blood flows through the connector 50 due to a pressure difference. This happens. In order to solve this problem, there are several types of methods and devices for preventing blood reflux or air inflow of the sap set. For example, looking at the "recess set for preventing reflux" in Korean Patent Registration No. 20-0429641 It is formed on one side of the fluid storage unit having a “∪” shape so that a certain amount of the fluid to be administered is always stored, and the fluid having a “∩” shape is discharged in a downward direction so that the stored fluid connected to one side of the fluid storage unit can be discharged downward. It is made up of wealth.
