Description

Technical Field

[0001] The utility model relates to the technical field of medicine dispensing, in particular to an auxiliary medicine dispensing device. Background Art

[0002] Liquid preparation is an indispensable and important part of clinical medicine, especially in the intravenous preparation center of the hospital, where nursing staff bear tremendous work pressure. They need to prepare thousands of bags of liquid medicine every day to ensure that patients can receive the drugs needed for treatment on time and in the right amount. In this process, the disposable 50ML syringe has become their most effective assistant. Generally, the two units of 20ML and 50ML are more commonly used. However, it is this seemingly simple tool that brings convenience to the dispensers, but also hides considerable hidden dangers. Dispensers hold disposable syringes every day and repeatedly perform hundreds of suction and injection actions of liquid medicine. These seemingly insignificant actions pose a serious threat to their hand health. Since the pressure difference between the air pressure in the infusion bag and the air pressure in the syringe is not large, a large external force is required to push the syringe. Long-term and repeated pressurized injection not only causes severe keratinization of the palm skin of the dispensers' fingers, but may also induce palmar joint tenosynovitis. These diseases not only bring great inconvenience to the daily work of dispensers, but also bring them great pressure on the mental level. Utility Model Content
