AI Technical Summary

Technical Problem

Existing blood leakage detection alarm devices are difficult to adjust precisely when the sponge fits the puncture site, leading to missed detections or false alarms. Furthermore, the disinfection process is inconvenient, affecting patient comfort and safety.

Method used

A wearable blood leakage sensing alarm device was designed. The device uses an inflation mechanism consisting of an air cylinder, a pressure rod, a plug, a valve body, and a valve to achieve convenient adjustment of the sponge to fit the puncture site. It is also equipped with a disinfection component, including a base plate, a second diaphragm, a leakage plate, and a limiting component, to enable pressing and disinfection operations after blood leakage.

Benefits of technology

It achieves a close fit between the sponge and the puncture site, avoiding excessive pressure, improving the wearing comfort and adjustment efficiency of the device, and allowing for convenient disinfection after blood leakage, thus improving patient safety and ease of operation.
