Pre-filled medicinal liquid injector

Abstract

The invention relates to an improved pre-filled medicinal liquid injector and belongs to a clinical medical appliance. The injector comprises a needle, a syringe and a push rod, wherein the syringe isan integrated glass syringe; the needle is fixedly inserted into a cone arranged on the front end of the glass syringe; the needle hole of the needle is communicated with the inner cavity of the glass syringe; the needle is provided with a needle sealing cap; the medical rubber piston is arranged in the inner cavity of the glass syringe; and the piston is in thread connection with the push rod; the turn-up of the bottom end of the glass syringe is provided with double side cuts. The injector is reasonable in structure and reliable in installation, can be directly used to contain medicinal liquid, is convenient in use, improves the utilization rate of the medicinal liquid, reduces medicinal liquid waste, reduces usage cost, facilitates the destruction and management after dispensable use,avoids repeated use and reduces pollution. The injector reduces intermediate processes between the delivery and the use by injection into human body of medicines, ensures the safety and reliability ofthe use of injection medicines of people and creates obvious economic and social benefits.

Description

technical field [0001] The invention relates to an improved syringe, which belongs to clinical medical equipment. Background technique [0002] The development of syringes has gone through all-glass syringes and disposable plastic syringes, and the connection between the needle taper and the needle is completed by metal and plastic needle seats. This type of syringe cannot store medicinal liquid for a long time, so when in use, it needs to be filled with liquid immediately for injection. On the one hand, the liquid medicine passes through other packaging media, and then transferred for use, the transfer of the liquid medicine will inevitably cause residual waste, especially for expensive medicines and biological medicines with a small amount of one-time use, this problem is more prominent; on the other hand, the There are serious problems in the destruction and use management of similar syringes, and the problem of repeated use is difficult to be completely solved, causing ...

This type of syringe cannot store the liquid medicine for a long time, so when in use, it needs to be filled with medicine immediately for injection

On the one hand, the liquid medicine passes through other packaging media, and then transferred for use, the transfer of the liquid medicine will inevitably cause residual waste, especially for expensive medicines and biological medicines with a small amount of one-time use, this problem is more prominent; on the other hand, the There are serious problems in the destruction and use management of similar syringes, and the problem of repeated use is difficult to be completely solved, causing serious pollution and great harm
