AI Technical Summary

Technical Problem

Existing devices for treating refractory ascites in cirrhosis are bulky, inconvenient to carry, and expensive, making it impossible to quickly deliver them to patients in special circumstances for draining ascites for testing and treatment.

Method used

A device was designed that includes components such as a support cylinder, a transparent shell, a scale plate, a threaded sleeve, a connecting tube, a delivery rod, a drainage tube, a fixing tube, a needle, a blocking mechanism, a delivery mechanism, and a pushing mechanism. The device uses a motor as a power source, automatically controls the flow of ascites through the blocking mechanism, records the amount extracted through the counting mechanism, and facilitates collection and testing through the collection mechanism.

Benefits of technology

The device has been miniaturized, making it easy to carry and use, reducing operating steps, improving extraction efficiency, reducing costs, and enabling convenient collection and testing of ascites.
