Automatic vent intravenous transfusion device for medical purpose

Abstract

The invention provides a medical automatic-exhaust intravenous infusion set and relates to the medical intravenous infusion apparatus. The medical automatic-exhaust intravenous infusion set is characterized that an exhaust pipe is mounted on a Murphy's dropper, one end of the exhaust pipe extends into the middle part of the inner cavity of the Murphy's dropper, and an exhaust cap discharging air instead of liquid is mounted at the other end of the exhaust pipe. The medical automatic-exhaust intravenous infusion set has the advantage of simple and convenient operation, for example, the liquid level automatically rises to the end of the exhaust pipe while the air is automatically discharged from the exhaust pipe without turning the Murphy's dropper over when a medicinal solution enters the Murphy's dropper.

Description

Technical field: [0001] The invention relates to a medical intravenous infusion device. Background technique: [0002] The intravenous infusion set is composed of a liquid inlet needle, an upper infusion tube, a Murphy's tube, a lower infusion tube, a liquid medicine filter, and a scalp needle, and a flow regulator is installed at the lower end of the lower infusion tube; A liquid medicine filter is connected, and the bottom of the liquid medicine filter is connected to the nipple interface by plugging, and the silicone hose and scalp needle are connected to the nipple interface. The liquid inlet needle has dual passages of air inlet and outlet, and an air filter is connected to the inlet passage, and the air filter is composed of an air inlet cap and a medical air filter membrane. [0003] During the infusion of the intravenous infusion set, gas is stored in the infusion tube and the Murphy's tube. The main function of the Murphy's tube is to infuse the liquid. People can ...

AI Technical Summary

Problems solved by technology

The medical venous infusion set has a simple structure and is easy to use, but it is also inconvenient: before the infusion, the infusion tube and the Murphy's tube must be artificially exhausted. The upper end of the infusion tube is located above the lower end of the upper infusion tube. The liquid medicine is injected into a part of the Murphy's tube, and after part of the air in the Murphy's tube is discharged through the lower infusion tube, the Murphy's tube is erected until the liquid medicine Exported through the infusion tube

Due to the overturning operation of this exhaust method, the phenomenon of unsuccessful or insufficient exhaust often occurs.
