Abstract

The present invention relates to a vial syringe filter cap having a metal tip and, more particularly, to a syringe filter cap which comprises a metal tip, a filter, and a housing and protects an injection needle. In addition, the vial syringe filter prevents foreign substances such as minute glass or a rubber piece precipitated inside the vial or the ampoule from being introduced into the syringe when an injectable solution is suctioned and charged from the vial and the ampoule, so as to prevent the foreign substances from being injected into a human body, and can charge the injectable solution without exposing the injection needle to the outside. Further, the vial syringe filter has a groove formed on the outer surface of the housing so that negative pressure is generated inside the vial, so as to solve a problem that the injectable solution is not charged well, and prevent a safety accident which may be generated by piercing by the injection needle when the injection needle is exchanged. Furthermore, the syringe filter cap comprises an inclined metal tip and a ventilating groove formed on the outer surface of the housing.

Description

금속팁을 구비한 바이알용 주사기 필터캡Syringe filter cap for vials with metal tip
본 발명은 금속팁을 구비한 바이알용 주사기 필터캡에 관한 것으로서, 보다 상세하게는 금속팁, 필터, 하우징을 구비하여 주사바늘을 보호함과 아울러 바이알이나 앰플에서 주사액을 흡입충전할 때 바이알이나 앰플 내부에 침전된 미세한 유리나 고무조각 등의 이물질이 주사기에 들어가는 것을 막아 인체내부에 이물질이 주사되는 것을 방지하고 주사바늘을 외부로 노출시키지 않고도 주사액을 충전할 수 있도록 하며 하우징 외면에 홈을 구비하여 바이알 내부에 음압이 생겨 주사액 충전이 잘 되지 않는 문제를 해결할 수 있도록 하며 주사바늘 교체시 바늘에 찔려 발생할 수 있는 안전사고를 방지하는 주사기용 필터캡에 관한 것이다.The present invention relates to a syringe filter cap for a vial having a metal tip, and more particularly, to a syringe or cap with a metal tip, a filter, and a housing to protect an injection needle and to inhale and refill an injection solution from a vial or ampoule. It prevents foreign substances such as fine glass or rubber fragments deposited inside the syringe from being injected into the body to prevent injection of foreign substances into the human body, fills the injection liquid without exposing the needle to the outside, and has a vial on the outer surface of the housing. The present invention relates to a filter cap for a syringe which prevents a safety accident that may be caused by a needle stick when a needle is replaced and a negative pressure is generated to prevent a problem of filling a syringe.
주사액 유리앰플은 목을 부러뜨려서 사용하기 때문에 미세한 유리조각이 주사액에 섞이게 된다. 주사액 바이알은 상부에 고무마개가 있고, 주사바늘로 고무마개를 관통하여 사용하기 때문에 미세한 고무조각이 주사액에 섞이게 된다. 미세한 유리조각이나 고무조각은 주사액과 같이 주사기에 흡입 충전되고, 결국 인체에 같이 주사되는 문제가 있다.Injection glass ampoules are used to break the neck, so fine glass fragments are mixed into the injection solution. The injection vial has a rubber stopper on the top, and fine rubber pieces are mixed with the injection because the injection needle penetrates the rubber stopper. Fine glass pieces or rubber pieces are inhaled and filled into the syringe like the injection solution, and thus have a problem of being injected into the human body.
의료계에서는 미세한 유리조각 등 이물질이 주사바늘을 통해 인체로 주사되어 혈전을 일으켜 심근경색, 뇌졸증과 같은 치명적인 질환을 유발할 수 있다는 가능성을 제기하였다.The medical community has raised the possibility that foreign substances such as fine glass fragments can be injected into the human body through needles, causing blood clots to cause fatal diseases such as myocardial infarction and stroke.
식약청 연구용역 보고서에서도 유리앰플의 주사액에 섞인 유리파편들이 정맥주사를 통해 약물과 함께 체내에 주입되면 폐, 간, 비장 등 장기에서 염증반응과 육아종 형성 등 병리학적 변화를 일으킬 가능성도 제기한 바있고, 특히 2004년 식약청 연구용역보고서에는 사람의 폐 모세혈관 지름이 10㎛이므로 이보다 큰 유리파편 같은 불용성 이물질이 인체에 축적되면 폐색전증과 같은 심각한 질환을 유발할 수 있음을 지적하였다.The KFDA research report also raised the possibility that glass fragments mixed with the injection of glass ampoules can be injected into the body through intravenous injection, causing pathological changes such as inflammatory reactions and granuloma formation in organs such as lungs, liver and spleen. In particular, the Korea Food and Drug Administration's 2004 research report pointed out that since human lung capillary diameter is 10 μm, insoluble foreign substances such as glass fragments larger than this may cause serious diseases such as pulmonary embolism.

도 1 내지 도 5를 참조하면 상기 금속팁을 구비한 바이알용 주사기 필터캡(1)은 하우징(100)과 금속팁(200)으로 구성되며, 상기 하우징(100)은 허브삽입로(101), 허브밀착돌출부(102), 경사로(103), 주사바늘삽입로(104), 필터(105), 주사액유입구(106), 통기홈(107), 탈거지지대(108)를 포함하고, 상기 금속팁(200)은 하우징결합부(201), 선단부(202)를 포함한다.1 to 5, the syringe filter cap 1 for a vial having the metal tip is composed of a housing 100 and a metal tip 200, and the housing 100 is a hub insertion path 101. Hub contact protrusion 102, inclination 103, needle injection path 104, filter 105, injection liquid inlet 106, aeration groove 107, stripping support 108, the metal tip ( 200 includes a housing coupling portion 201, the tip portion 202.
이때, 상기 하우징(100)은 몸체를 이루는 부분으로 관형이며 합성수지재질로 형성되었다.At this time, the housing 100 is a tubular part formed of a body was formed of a synthetic resin material.
아울러 허브삽입로(101)는 주사바늘조립체(미도시)의 허브가 삽입되는 부분으로 허브가 삽입고정되었을 때 밀착되도록 허브와 짝을 이루도록 하우징 내에 관통된다.In addition, the hub insertion path 101 is a portion into which the hub of the needle assembly (not shown) is inserted, and penetrates into the housing to mate with the hub so as to be in close contact when the hub is inserted and fixed.
이때, 허브삽입로(101)에는 주사바늘조립체의 허브와 고정과 밀착을 위해 돌출된 형태의 허브밀착돌출부(102)가 형성될 수 있다.At this time, the hub insertion path 101 may be formed in the hub contact protrusion 102 of the protruding form for fixing and close contact with the hub of the needle assembly.
