AI Technical Summary

Technical Problem

Existing gastrointestinal decompression devices are prone to interruption during use due to the need to replace the bottle when there is a large amount of fluid, and the elastic ring can easily cause discomfort to the patient when resolving blockages.

Method used

A gastrointestinal decompression device was designed, which adopts a structure that uses an anti-clogging connector and a liquid storage bottle alternately. The anti-clogging connector prevents clogging through the design of thick and thin tubes and ribs. The liquid storage bottle achieves continuous suction through a solenoid valve and a water level sensor. The negative pressure pump and the liquid storage bottle work alternately.

Benefits of technology

It achieves effective separation of liquid and gas and continuous aspiration, avoiding interruption of the gastrointestinal decompression process and patient discomfort, and improving the convenience and comfort of use.
