본 발명은 주사기의 선단에서 주사바늘이나 캡을 결합 사용하는 연결접속구에 관한 것으로서, 좀더 상세하게는 주사기 본체 선단에 원터치로 착탈 결합하되, 중앙 관통구 외측으로 내주연에 나사산을 형성하는 링형 접속부를 형성하여 주사바늘이나 캡의 상단을 삽입하여 나선 결합 사용하므로 외관미와 결합 견고성을 우수하게 제공하는 주사기용 착탈식 연속접속구에 관한 것이다.The present invention relates to a connecting connector using a needle or a cap coupled to the tip of the syringe, more specifically, the ring-shaped connecting portion that is detachably coupled to the tip of the syringe body with a one-touch, the inner periphery outside the central through hole The present invention relates to a detachable continuous connector for a syringe that provides excellent appearance and coupling robustness by inserting the upper end of a needle or a cap by forming a spiral.

일반적으로 주사기는 의료 용품중의 하나이다.In general, a syringe is one of the medical supplies.

이와 같은 주사기는 약을 주사하거나 혈액을 채취하는 채혈, 그 밖에 다양한 의료 목적으로 사용된다.Such syringes are used for blood injection to inject medicine, to draw blood, and for various other medical purposes.

이와 같은 주사기는 후방에 가압 또는 인출 작동하는 피스톤과, 상기 피스톤이 삽입되는 주사기 본체 및, 상기 주사기 본체의 선단에 결합되는 주사바늘 등으로 구성하되, 상기 주사기 본체 선단에는 주사바늘 대신에 캡이나 그 밖에 채혈 도구, 원심 분리용 도구 등 각종 의료용 도구를 연결 사용하게 되는 것이다.Such a syringe is composed of a piston which is pressurized or drawn out at the rear, a syringe body into which the piston is inserted, and an injection needle coupled to the tip of the syringe body. In addition, various medical tools such as blood collection tools and centrifugal separation tools will be used.

이때, 상기 주사기 본체 선단에는 연결 접속구가 일체 또는 결합 형태로 형 성되는데, 상기 연결접속구의 하부 외주연으로 나사부를 형성하여 상기한 주사바늘, 캡, 그 밖에 채혈 도구 등을 나사 결합 사용하게 되는 것이다.In this case, the connecting end is formed in the form of a single or combined connection to the tip of the syringe body, by forming a screw portion in the lower outer periphery of the connecting connection is to use the needle, the cap, other blood collection tools, such as screw coupling. .

그러나 상기한 종래 연결 접속구는 연결 접속구의 나사부가 외부로 노출되어 외관미를 저해함은 물론 상기 나사부에 상기한 주사바늘, 캡, 그 밖에 채혈도구 등이 단순히 나사 결합되는 형태로 결합되기 때문에 나사산 마모 등에 의한 유동으로 나사 결합 상태를 견고히 유지함이 부족한 문제점이 있었다.However, the conventional connection port is exposed to the outside of the threaded portion of the connection port to hinder the appearance, as well as the threaded wear because the needle, the cap, and other blood collection tools, such as the screw portion is coupled in the form of simply screwed together There was a problem that it is insufficient to maintain the screw connection state firmly by the flow.

본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 발명된 것으로서, 주사기 본체 선단에 원터치로 착탈 결합하되, 중앙 관통구 외측으로 내주연에 나사산을 형성하는 링형 접속부를 형성하여 주사바늘이나 캡을 삽입하여 나선 결합 사용하므로 나사산이 외부에서 확인되지 않아 외관미가 우수함은 물론 링형 결합부 내부에서 나사 결합되기 때문에 유동 방지로 결합 견고성을 우수하게 제공하는데 그 목적이 있다. The present invention has been invented to solve all the problems of the prior art, one-touch detachable coupling to the tip of the syringe body, by forming a ring-shaped connection to form a thread on the inner periphery outside the central through hole to form a needle or cap Since the screw thread is inserted and used, the screw thread is not confirmed from the outside, and the appearance is excellent, as well as the screw is screwed inside the ring-shaped coupling part, and thus the purpose is to provide excellent coupling robustness by preventing flow.

이러한 본 발명은,This invention,

몸체 상부 내측에 결합홈과, 상기 결합홈 내주연에 링형 결합돌기를 형성하여 주사기 본체 선단의 링형 결합요홈을 갖는 결합단차부에 원터치로 착탈 결합 사용하되,A coupling groove is formed inside the upper portion of the body, and a ring-shaped coupling protrusion is formed at the inner circumference of the coupling groove to be detachably used for one-touch coupling portion having a ring-shaped coupling groove at the tip of the syringe body.

상기 몸체의 하부 중앙에는 토출구와 상기 토출구 외측에 내주연으로 나사산을 갖는 링 형태의 결합부를 형성하여 상기 결합부의 나사산에 주사바늘이나 캡이 삽입되게 나사 결합하도록 구성함에 그 특징이 있다.The lower center of the body is characterized in that it is configured to screw-in so that the injection needle or the cap is inserted into the thread of the coupling portion by forming a ring-shaped coupling portion having a screw thread in the inner periphery of the discharge port and the discharge port outside.

본 발명 상기 몸체의 결합홈에는 바닥 외측으로 결합홈을 형성하여 주사기 본체의 선단면에 밀착되는 기밀링을 삽입 구성함에 그 특징이 있다.The present invention is characterized in that the coupling groove of the body is formed by inserting an airtight ring in close contact with the front end surface of the syringe body by forming a coupling groove on the bottom outside.

이러한 본 발명은 주사기 본체 선단에 원터치로 착탈 결합하되, 중앙 관통구 외측으로 내주연에 나사산을 형성하는 링형 접속부를 형성하여 주사바늘이나 캡을 삽입하여 나선 결합 사용하므로 나사산이 외부에서 확인되지 않아 외관미가 우수함은 물론 링형 결합부 내부에서 나사 결합되기 때문에 유동 방지로 결합 견고성을 우수하게 제공하는 효과를 갖는 것이다.The present invention is one-touch detachable coupling to the tip of the syringe body, but forms a ring-shaped connection to form a screw thread on the inner periphery outside the central through hole by inserting a needle or a cap, so the screw thread is not confirmed from the outside appearance As well as excellent beauty, because it is screwed inside the ring-shaped coupling portion is to have the effect of providing excellent binding robustness by preventing flow.
