Description

Sterile connector of infusion bottle

[ field of technology ]

The utility model relates to an aseptic connector of an infusion bottle.

[ background Art ]

The connector on the bottle mouth of the infusion bottle is used for covering the bottle mouth of the infusion bottle, sealing and keeping sterile so as to be used for sucking the liquid medicine in the bottle or adding the liquid medicine, and the other connector can be used for enabling an infusion apparatus and the like to puncture and insert the bottle so as to drain the solution in the bottle out for infusion and the like. In clinic, the preparation of the medicament is often needed to be added into an infusion bottle or the solution is needed to be pumped out from the infusion bottle, and the most common clinical use at present is to puncture the needle head from the rubber pad of the joint, and then pull out the medicament after the medicament is added or the solution is pumped out. In clinical use, the infusion bottle is usually erected on the table, so when the solution is required to be pumped from the bottle, the infusion bottle is required to be taken up and inverted to be positioned at the bottle mouth, and the solution can be pumped, which brings great inconvenience to clinical work, especially when one person independently performs one-hand operation and the solution is required to be pumped from the bottle.

Since the puncture site of the rubber pad is exposed, bacteria are liable to stay there, and thus, when a solution is required to be sucked from the bottle or a medicine liquid is required to be injected into the bottle, the needle is required to be sterilized and then inserted from the rubber pad, and the operation is extremely inconvenient. In addition, rubber particles are easy to generate when the needle is used for penetrating the rubber pad, particularly when the needle is used for repeatedly penetrating the rubber pad, the probability of generating the rubber particles is greatly improved, some rubber particles are very tiny and cannot be identified by naked eyes, and tiny rubber plug particles can be input into a patient in severe cases.

Because the sharp needle is required to be used for sucking the solution in the infusion bottle or injecting the medicine into the bottle, and the needle is extremely easy to cause needle puncture in the use process, the occupational exposure opportunity of medical staff is increased.

The present utility model has been made based on the circumstances.
