Oxygen cabin controlled by computer

Abstract

The invention discloses an oxygen cabin controlled by a computer. The oxygen cabin comprises a touch screen industrial control integrated machine, a PLC, a cabin body, a humidification antistatic device for inflating the cabin body with humidity, an oxygen adding device for inflating oxygen into the cabin body, an oxygen exhausting device for exhausting oxygen inside the cabin body out of the cabin body, a temperature adjusting device for adjusting the temperature inside the cabin body and a monitoring device for detecting the state inside the cabin body. The dehumidification antistatic device, the oxygen adding device, the oxygen exhausting device, the temperature adjusting device and the monitoring device are electrically connected with the PLC. The PLC is connected with the touch screen industrial control integrated machine through an RS 485 communication circuit. The oxygen cabin has the advantages that the varieties of monitored parameters are complete, the automatic control degree is high, the control process is stable and accurate, parameter fluctuations are small, it is ensured that the pressure, temperature, humidity and the oxygen concentration of the oxygen cabin are still within the set range, and the using effect and using safety of a patient are ensured.

Description

technical field [0001] The invention relates to the technical field of medical oxygen chambers, in particular to a computer-controlled oxygen chamber. Background technique [0002] Hyperbaric oxygen is a technology that uses high-pressure oxygen in medicine to achieve the purpose of health care. It allows users to absorb pure oxygen in a pressurized environment for a period of time, which can increase the ability of blood to carry oxygen and improve hypoxia in the body. [0003] The known hyperbaric oxygen chamber mainly has a cabin body, a hatch door and a control system, a monitoring system, a pressure system and an oxygen supply system arranged inside and outside the cabin. Users inside the cabin or operators outside the cabin can use the control system inside or outside the cabin to set parameters such as pressure and time to control the pressure system and oxygen supply system for pressurization, decompression and oxygen supply. , and provide oxygen to the users in the...

AI Technical Summary

Problems solved by technology

However, the current control system of the hyperbaric oxygen chamber has the problems of poor control accuracy, unstable pressurization and decompression process, and large pressure fluctuations.

Moreover, the oxygen concentration in the hyperbaric oxygen chamber is high, and when encountering electric sparks, it is easy to cause a deflagration fire, resulting in the consequences of the destruction of the cabin
