Description

A kind of vial quantitative injector

technical field

The invention belongs to the technical field of medical devices, in particular to a vial quantitative injector.

Background technique

Vial vial, also known as borosilicate glass or soda lime glass tube (molded) injection bottle, is a small bottle sealed with a rubber stopper. There are brown, transparent and other types, and the vials made of borosilicate are the mainstream products on the market. The neck is thinner, and the thickness below the neck is the same. The mouth of the bottle is slightly thicker than the bottle neck and slightly thinner than the body of the bottle, and is generally used for the packaging of powder injection medicines. In the early days, penicillin was mostly used in its dressing, hence the name vial.

At present, when dispensing medicine to a vial, a syringe is generally used to draw the liquid from the infusion bottle, and then the needle of the syringe is inserted into the vial to inject the liquid into the vial, and the vial is manually shaken from side to side to the liquid in the vial. Then insert the needle into the vial and invert the vial, and suck out the medicinal liquid in the vial; after the suction is completed, inject the medicinal liquid in the vial into the infusion bottle, pull out the syringe, and finally complete the vial. Transfer dispensing of internal medicines. This dispensing method is troublesome, inefficient and time-consuming, especially in a large number of dispensing occasions, because of its high labor intensity, it cannot ensure quantitative injection of each vial, and the infusion bottle is suctioned and aligned with a hand-held syringe. The way of injecting liquid in vials has certain risks and is likely to cause harm to medical staff.

In addition, in recent years, there have been more and more harmful gases in the air, and air-borne diseases, viruses and bacteria such as SARS, influenza, and avian influenza have emerged one after another. Filter out harmful gases and germs in the air. When these poisonous gases or germs flow into the body of a healthy person with the air into the infusion, it will cause side effects of the infusion and even get sick.

In addition, when the vial is dispensed, the pressure in the vial increases due to liquid injection, which leads to the problem that the liquid medicine is sprayed out when the needle of the syringe is pulled out.
