Monitoring system capable of detecting gas leakage of pipelines on sickroom equipment belts

Abstract

The invention provides a monitoring system capable of detecting gas leakage of pipelines on sickroom equipment belts. The monitoring system comprises a plurality of sickrooms, medical equipment belts arranged in corresponding sickrooms and a nurse station, wherein a medical gas terminal component for outputting medical gas by a gas inlet pipe is arranged on each medical equipment belt; a stop valve for controlling the on-off of the gas is arranged on each gas inlet pipe; a flow sensing chip for measuring gas flow and a PCB (Printed Circuit Board) are packaged on an air flow pipeline at the gas outlet end of each stop valve; a chip signal conversion module which is electrically connected with the flow sensing chip and the PCB in each sickroom and converting a voltage signal of each flow sensing chip into an RS485 signal is also arranged in the sickroom; an RS485 switch and an area gas monitoring alarm box are arranged in the nurse station; the chip signal conversion module in each sickroom feeds back respective RS485 signal to the RS485 switch in the nurse station; the RS485 switch transmits the signal to the area gas monitoring alarm box for realizing remote monitoring alarm.

Description

[0001] 【Technical field】 [0002] The invention relates to a medical terminal detection technology, in particular to a monitoring system capable of detecting air leakage of equipment in a ward. [0003] 【Background technique】 [0004] At present, the medical gases commonly used in hospitals include oxygen, negative pressure, compressed air, laughing gas (anesthetic gas), carbon dioxide, etc. The gas pressure in the medical gas pipeline is usually relatively high. Taking the medical oxygen system as an example, the national standard requires terminal pressure It must not be lower than 0.4MPa. Therefore, it is particularly important to monitor the gas pressure in the medical gas pipeline (referred to as "gas circuit", the same below). Before there was no central gas supply system, the hospital had to move oxygen cylinders, negative pressure suction devices, air compressors and other bottled gases into wards or operating rooms to use these gases, which greatly increased the labor ...

AI Technical Summary

Problems solved by technology

Regardless of whether the manufacturer provides after-sales service or the hospital itself conducts maintenance and management, they are basically in a passive state, that is, they wait until the system fails and cannot be used before dealing with it or reporting it to the manufacturer.

This will not only affect the use of the hospital, delay the maintenance time, but also increase the maintenance cost
