Description

Auxiliary extractor of syringe

Technical Field

The utility model relates to a medical apparatus, in particular to an injector auxiliary extractor which is suitable for extracting and injecting liquid medicine into a sealed medicine container for dispensing medicine by a medical injector.

Background

At present, medical syringes are widely used clinically, and common syringes adopt a needle cylinder and a needle head structure, so that liquid medicine needs to be sucked from a medicine bottle before the liquid medicine is injected into a human body. When operations such as sucking liquid medicine and injection are clinically configured, the medicament bottle mouth is disinfected firstly, then the equivalent air of the liquid medicine is injected into the bottle, so that the internal force of the bottle is increased, negative pressure is avoided, then the medicament bottle and the syringe are reversed, the bottle is shaken slightly until the medicine is dissolved, a medical operator fixes the needle cylinder by fingers and pulls the plunger handle to suck the required medicine amount, and the hand can not touch the needle head in the liquid medicine sucking process. Medical personnel at oncology department absorbs interior liquid medicine in-process of medicament bottle with the syringe, often use radiotherapy and chemotherapy medicament, still need inject into the liquid medicine and mix the medicine and dispense in the confined medicament bottle, syringe needle point end pierces the medicament bottleneck and when injecting the medicament in to the medicament bottle in the operation process, need medical care operator with syringe needle point end aim at medicament bottle cork lid power with inserting, the syringe needle is because the interior pressure of medicament bottle is big, sometimes the medicament can outwards splash in the twinkling of an eye, it is healthy to harm medical care operator. Therefore, in the operation process of the medical care operator, the sharp end of the needle head needs to be aligned with the soft plug cover of the medicament bottle, the operation requirement of the medical care operator is high, and excessive psychological pressure is caused. To avoid hazardous contamination, a box-type transparent shield is generally used as a syringe splash guard, operating within which it presents problems: the medical care operator is difficult to observe the needle tip in a short distance to be aligned with the soft plug cover of the medicament bottle, the dose is difficult to observe, and the volume is too large, so that inconvenience is brought to the operation.
