Embodiment Construction

[0107] Please refer to Figure 1A , Figure 1B and Figure 1C , The first embodiment of the present invention includes a plug main body 1 (plug main body), which is an elastic cylindrical object. The plug body 1 has a valve membrane 1o (valve membrane), which is located in the middle area of ​​the plug body 1, and the middle area of ​​the valve membrane 1o has a cut portion 1a (cut portion), when a pressure is applied from the outside in a radial direction When P is attached to the main body 1 of the plug, the notch portion 1a can be presented in a closed state. The plug body 1 is an elastic body, such as rubber, and the notch 1 a of the plug body 1 is in a straight line, and its extending direction extends in the middle area of ​​the plug body 1 . Moreover, the outer diameter D1 of the plug main body 1 will be larger than the inner diameter D2 of the injection and extraction port 2a (injection and extraction port), so the injection and extraction port 2a will generate pres...

Abstract

A liquid medicine or the like injection and extraction port seal valve comprises a plug main body (1) in the form of an elastic body formed with a linear cut portion (1a) or slit portion (1f) in the central region vertically extending therethrough, the outer diameter (D1) of the plug main body (1) being larger than the inner diameter (D2) of an injection and extraction port (2a) for liquid medicine, the arrangement being such that tightly fitting the plug main body (1) in the injection and extraction port (2a) for liquid medicine or the like produces a clamping pressure on the cut portion (1a) or slit portion (1f) to seal it. The cut portion (1a) or slit portion (1f) of the plug main body (1) is elastically deformed to open by tightly fitting the front end portion (3) of a syringe or connector, and is elastically restored to its original sealed state by pulling out the front end portion (3) of the syringe or connector.

Description

technical field [0001] The present invention relates to a sealing device for injecting and withdrawing ports of liquid medicaments in the field of medicine, which can directly inject or extract liquid medicaments through the front end of a syringe or a connecting member. And in the case where the liquid medicine is to be withdrawn from the liquid medicine bottle or the liquid medicine container or when the liquid medicine is to be injected into the mixing infusion tube for transferring blood, the injection needle need not be used. Background technique [0002] The device of the present invention has a plug body, and the plug body is provided with a notch, a narrow mouth or a conical hole that can be inserted into the front part of the syringe or the connecting member, and the plug body can be tightly inserted into the liquid medicine bottle, liquid medicine One of the liquid medicaments, such as containers, mixing injection tubes, or similar objects, is injected into the ext...
