Description

Infusion bag medication plug cap

technical field

The utility model relates to a medical device, in particular to a medicine stopper cover for an infusion bag.

Background technique

Medical plugs are divided into medical infusion plugs or dosing plugs. Medical plugs are used to seal large infusion bags. While sealing and protecting the liquid medicine, it must be easy to open and conveniently add medicine to the inside or infuse medicine to the patient. Therefore, there are high requirements for the sanitation, easy operation and sealing of medical plugs.

In order to facilitate the operation of medical personnel, it has become the main trend of medical plugs to develop and design good sealing and easy-to-puncture plugs. And many use aluminum-plastic composite cover wrapping material in the prior art. In order to meet the tightness, the acupuncture part is often set thicker. Therefore, during use, the user breaks off the plastic cover part, and then punctures the needle-punched part usually by means of a special tool. The operation steps are complicated and difficult to operate.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a medicine plug cover for an infusion bag with good sealing performance and simple and convenient operation.

The purpose of this utility model is achieved through the following technical proposals: the medicine stopper cover of the infusion bag, which includes a combined cover, a pipe fitting and a rubber stopper, the described combined cover is connected to the pipe fitting, and the described combined cover includes an outer cover and an inner cover, The inner cover is arranged inside the outer cover, and a rubber plug is arranged inside the combined cover, and the upper end surface of the rubber plug is provided with an acupuncture point, and the side flange of the rubber plug is inserted into the clamping position of the inner wall of the pipe fitting. inside the groove.

Further, the top of the rubber plug is provided with an axially extending upper flange, and the upper flange is inserted into the slot on the side wall of the inner cover.

Further, the lower end surface of the rubber plug is provided with a concave bottom groove, and the bottom groove is aligned with the acupuncture point.

Further, the inner side of the top wall of the outer cover is also provided with a connecting portion extending downward, and the connecting portion is integrally formed on the cylinder inside the top wall of the outer cover, and the inner cover is correspondingly connected A tear hole is opened on the part, and the connecting part is connected to the inner cover through the tear hole, and is used to lift the inner cover.

Further, the acupuncture point is set at the center of the upper end surface of the rubber plug, and the acupuncture point is in the shape of an inverted cone.

The utility model has the following advantages:

1. By setting the acupuncture point at the center of the upper end surface of the rubber plug, and the acupuncture point is in an inverted conical shape, it is beneficial to align the acupuncture point with the acupuncture force and concentrate the acupuncture force on one point, thereby reducing the The force required to puncture the rubber stopper.

2. By inserting the side flange of the rubber plug into the clamping groove inserted in the inner wall of the pipe, at the same time, an axially extending upper flange is provided on the top of the rubber plug, and the upper flange is inserted in the The slot on the side wall of the inner cover greatly improves the sealing effect of the rubber plug.

3. A concave bottom groove is provided on the lower end surface of the rubber plug, and the bottom groove is set corresponding to the acupuncture point, so the thickness of the acupuncture point is greatly reduced, which is convenient for puncturing, making the operation simpler and more convenient.
