It relates to a drainage port for a sap bag consisting of a rubber stopper that is mounted, coupled to the top of the port body to cover the rubber stopper, and a soft inner auxiliary cap installed between the rubber stopper and the closing cap.

환자에게 의료적 목적으로 투여되는 각종 수액(輸液; Parenteral nutrition)이나 복막투석액(Peritoneal dialysis solution), 혈액 등은 주로 넌-피브이씨(Non-PVC) 재질의 플라스틱 수액백(medical solution bag)에 보존된다. 그리고 이러한 수액백에는 통상 배액포트(drainage port)와 주입포트(injection port)가 설치되어 있다. 상기 배액포트(drainage port)는 스파이크(spike)를 삽입하여 백 내부에 저장된 약물을 배액하는 용도로 사용되고, 상기 주입포트는 주사기를 꽂아 백 내부로 항생제 등 다른 약물을 주입하는 용도로 사용된다.Parenteral nutrition, peritoneal dialysis solution, and blood, which are administered to patients for medical purposes, are usually placed in a non-PVC plastic medical solution bag. Are preserved. In addition, such a sap bag is usually provided with a drainage port and an injection port. The drainage port is used to drain the drug stored in the bag by inserting a spike, and the injection port is used to inject other drugs such as antibiotics into the bag by inserting a syringe.

일반적으로 의료용 수액백에 설치되는 포트 내부에는 스파이크나 주사기를 꽂는 고무마개가 설치되어 있다. 그런데 주입포트의 경우에는 상기 고무마개에 가느다란 주사기가 삽입되기 때문에 별 문제가 없으나, 굵은 스파이크가 삽입되는 배액포트의 경우에는 고무마개에 스파이크를 삽입하기가 힘들 뿐 아니라, 스파이크 자국에서 누액이 발생할 우려가 있다.In general, a rubber stopper for inserting a spike or a syringe is installed in a port installed in a medical fluid bag. However, in the case of the injection port, there is no problem because a thin syringe is inserted into the rubber stopper, but in the case of the drainage port in which the thick spike is inserted, it is difficult to insert the spike into the rubber stopper and leakage occurs in the spike marks. There is concern.

이러한 문제점을 해결하기 위하여 본 발명자는 실용신안등록 제20-0429645호(2006년 10월 19일)에서, 상층 원통부와 하층 원통부가 단층구조를 갖도록 한몸으로 이루어지고, 상기 상층 원통부의 상면 중앙에는 원호형 홈부가 형성되어 있으며, 상기 하층 원통부의 하면 중앙에는 원뿔형 홈부가 형성되어 있는 고무마개를 제안한 바 있다.

상기 고무마개를 사용한 배액포트는 스파이크의 삽입이 용이하고, 배액 도중에 스파이크가 저절로 빠지거나, 스파이크 자국에서 누액이 발생할 우려가 없는 효과는 있으나, 고무마개에 스파이크를 찔러 넣는 과정에서 고무파편이 발생하여 인체로 유입될 수도 있다는 우려를 해소할 수는 없었다. The drainage port using the rubber stopper is easy to insert the spike, the spike spontaneously fall out during the drainage, there is no effect of leaking from the spike marks, but the rubber debris in the process of inserting the spike into the rubber stopper It could not solve the concern that it might enter the human body.

이러한 우려를 해소하기 위하여 실용신안등록 제20-0452452호(2011년 02월 21일) 등에서는 고무마개를 사용하지 않는 배액포트가 소개되어 있다. 이러한 구조의 배액포트는 스파이크에 의해서 고무파편이 발생할 우려는 없으나, 스파이크를 빼낸 이후에 백 내부에 남아있던 약물이 밖으로 흘러나오지 않도록 주입관을 보조마개로 주입관을 막아주어야 하기 때문에 구조가 복잡하고 사용이 불편한 단점이 있었다.In order to alleviate such concerns, Utility Model Registration No. 20-0452452 (February 21, 2011) and the like introduce drainage ports that do not use rubber stoppers. The drainage port of such a structure does not have the risk of rubber fragments caused by spikes, but the structure is complicated because the injection tube should be blocked with an auxiliary plug so that the drug remaining inside the bag does not flow out after the spike is removed. It was inconvenient to use.
