Description

잔량 배출 기능을 갖는 시린지용 개스킷 {Gasket for syringe with residual discharge}Gasket for syringe with residual discharge}

본 발명은 잔량 배출 기능을 갖는 시린지용 개스킷에 관한 것으로서, 보다 상세하게는 주사액이 남지 않고 전량 인체에 주입되도록 해주는 주사액 잔량 배출부재가 형성되되, 상기 주사액 잔량 배출부재는 개스킷 중앙에서 길이 방향으로 길게 빠져 나와 소정의 깊이를 갖는 주사액 배출구에 삽입되어 끼워지면서 공간에 채워진 주사액을 외부로 안전히 배출시킬 수 있는 잔량 배출 기능을 갖는 시린지용 개스킷에 관한 것이다.The present invention relates to a gasket for a syringe having a residual amount discharging function, and more specifically, an injection liquid residual amount discharging member is formed to allow all the injection liquid to be injected into the human body without leaving an injection liquid, and the injection liquid residual amount discharging member is elongated in the longitudinal direction from the center of the gasket. The present invention relates to a gasket for a syringe having a residual amount discharge function capable of safely discharging an injection liquid filled in a space while being inserted into and inserted into an injection liquid outlet having a predetermined depth.

일반적으로 종래의 주사기는 약(drug)과 같은 액체를 수용하는 실린더와 이 실린더 내에서 미끄럼 운동을 하는 피스톤으로 구성되어 있다.In general, a conventional syringe is composed of a cylinder that accommodates a liquid such as a drug and a piston that slides in the cylinder.

상기 피스톤은 피스톤 몸체와 피스톤 헤드(개스킷)를 가지고 있는데, 상기 피스톤 헤드는 스크루잉(screwing)등의 처리를 하여, 피스톤 몸체의 전단부이 실린더의 내부에 미끄러져 들어가면서 실린더의 내부 영역을 밀봉시킨다.The piston has a piston body and a piston head (gasket), wherein the piston head is subjected to processing such as screwing, so that the front end of the piston body slides inside the cylinder and seals the inner region of the cylinder.

종래에는, 화학저항 및 열저항의 특성상, 실린더는 사이클로올레핀수지(cycloolefin resin)류로 제작하는 것을 선호해온 것으로 알려져 있다.Conventionally, it is known that, due to the properties of chemical resistance and heat resistance, cylinders have been preferred to be made of cycloolefin resins.

한편, 피스톤 헤드가 실린더의 내벽을 따라 미끄러져 들어가면서 상기 내벽 내에서 유체-타이트니스(liquid-tightness)를 유지하여야 하기 때문에, 피스톤 헤드는 부틸고무(butyl rubber)와 같은 탄성중합체(elastomer)로 만들어졌다.On the other hand, since the piston head slides along the inner wall of the cylinder and must maintain fluid-tightness within the inner wall, the piston head is made of an elastomer such as butyl rubber. lost.

그리고, 주사기의 외측면에 표시되어 있는 눈금을 이용하여 주사할 적정량의 주사액을 유입한다. 적정량의 주사액이 상기 주사바늘 내로 유입되면, 주사하고자 하는 신체부위에 상기 주사바늘을 꼽고 근위단부의 누름부를 눌러 주사액이 신체내로 주입되도록 한다.Then, an appropriate amount of the injection solution to be injected is introduced using the scale displayed on the outer surface of the syringe. When an appropriate amount of the injection liquid flows into the injection needle, the injection needle is inserted into the body by inserting the injection needle into the body part to be injected and pressing the proximal end pressing portion.

이와같은 종래의 주사기는 반복해서 사용가능하도록 되어 있음으로써, 세척 및 소독을 하지 않거나, 또는 세척 및 소독이 완전히 이루어지지 않은 상태에서도 반복적으로 사용됨에 따라 각종 질병이 전염되는 원인이 되었다.Since such a conventional syringe is intended to be repeatedly used, various diseases are transmitted as it is not repeatedly cleaned and disinfected, or repeatedly used even in a state in which cleaning and disinfection are not completely performed.

또한 플런저 샤프트를 개방단부에 밀착시키더라도 상기 개방단부의 내측에 주사액이 여전히 남아 있게 됨으로써, 적정량의 주사액이 투약되지 못하는 문제점이 있었다.In addition, even if the plunger shaft is in close contact with the open end, the injection solution still remains inside the open end, so there is a problem in that an appropriate amount of injection solution cannot be dosed.

본 발명은 위와 같은 문제점을 해결하기 위하여 주사액이 남지 않고 전량 인체에 흡입되도록 하는데 그 목적이 있다.In order to solve the above problems, the present invention has the purpose of allowing all of the injection liquid to be inhaled without being left behind.

본 발명은 위의 목적을 달성하기 위하여 주사액이 남지 않고 전량 인체에 주입되도록 해주는 주사액 잔량 배출부재가 형성되되, 상기 주사액 잔량 배출부재는 개스킷 중앙에서 길이 방향으로 길게 빠져 나와 소정의 깊이를 갖는 주사액 배출구에 삽입되어 끼워지면서 공간에 채워진 주사액을 외부로 안전히 배출시킬 수 있는 잔량 배출 기능을 갖는 시린지용 개스킷에 관한 것이다.In order to achieve the above object, the injection liquid remaining amount discharge member is formed to allow the entire amount to be injected into the human body without leaving the injection liquid, and the injection liquid remaining amount discharge member is elongated in the longitudinal direction from the center of the gasket to inject the injection liquid with a predetermined depth. It relates to a gasket for a syringe having a function of discharging the residual amount that can safely discharge the injection liquid filled in the space while being inserted and inserted into the outside.

본 발명은 주사액 잔량 배출부재가 주사액 배출구의 내측에 안전히 삽입됨으로써, 주사액이 상기 주사액 배출구의 내측에 남지 않고 전량 인체에 주입됨에 따라 적량의 주사액이 인체에 투입되도록 해주는 효과도 있다.The present invention also has an effect of allowing the injection amount of the injection solution to be injected into the human body as the injection solution is discharged into the human body without being left inside the injection solution discharge port, by safely inserting the injection amount remaining member inside the injection solution discharge port.
