Description

Technical Field

[0001] The invention belongs to the technical field of hyperbaric oxygen chambers, and in particular relates to a gas analysis control device for an oxygen chamber. Background Art

[0002] In the modern medical system, hyperbaric oxygen chamber is an important treatment method. Oxygen and pressurized gas are used as media to treat anaerobic infection, CO poisoning, gas embolism, decompression sickness, hypoxic-ischemic encephalopathy, brain trauma, cerebrovascular disease, etc., so the quality of the gas source in the oxygen chamber directly affects the treatment effect. The main components of the gas in the oxygen chamber come from the source gas and the waste gas generated by human activities. In addition to the influence of the ambient gas at the air inlet, the source gas is mainly affected by the air compressor, gas storage tank and pressure pipeline of the compressed air. The existing oxygen chamber uses a single detector to control the quality of the source gas, which makes the workload large and cannot be monitored in real time, which is easy to cause low medical quality and equipment failures cannot be discovered in time. In addition, it focuses on the control and monitoring of the source gas, but ignores the physiological hygiene and comfort needs of the people in the cabin. Therefore, it is of great significance to design an oxygen chamber gas analysis and control device. Summary of the invention

[0003] In view of the above-mentioned defects, the present invention aims to provide a gas analysis and control device for an oxygen chamber, through which the gas quality in the oxygen chamber is monitored in real time, ensuring a stable gas supply in the chamber, timely discharge of waste gas, and comfort for personnel.

[0004] In order to achieve the above technical objectives, the following technical solutions are adopted: A gas analysis control device for an oxygen chamber, comprising an air compressor, an oxygen tank, an air filter, an air intake electric regulating valve, an exhaust electric regulating valve, an oxygen chamber and a gas analysis control system; the gas analysis control system comprises an air quality sensor, an air quality monitoring system, an oxygen concentration sensor, an oxygen concentration monitoring system and a control system; The air compressor is connected to an air filter, and the filtered compressed air passes through an air quality sensor and an air intake electric regulating valve in sequence before entering the oxygen cabin. An air quality sensor is also provided in the oxygen cabin, and the air quality sensor collects the filtered air quality data and the air quality data in the cabin, and then transmits them to the air quality monitoring system; The oxygen tank is directly connected to the oxygen cabin to provide oxygen for the oxygen cabin. An oxygen concentration sensor is provided in the oxygen cabin to collect oxygen concentration data in the oxygen cabin and transmit the data to the oxygen concentration monitoring system. The air quality monitoring system is used to monitor the air quality at the rear end of the air filter and in the oxygen chamber, and transmit the results to the control system; the oxygen concentration monitoring system is used to monitor the oxygen concentration in the oxygen chamber, and transmit the results to the control system; the control system is connected to the intake electric regulating valve and the exhaust electric regulating valve and is used to adjust the opening of the intake electric regulating valve and the exhaust electric regulating valve.

[0005] Furthermore, there are multiple oxygen concentration sensors, which are respectively connected to the oxygen concentration monitoring system.

[0006] Furthermore, there are two oxygen concentration sensors.

[0007] Furthermore, the air quality sensor and the oxygen concentration sensor each include an audible and visual alarm device.

[0008] Furthermore, the air compressor is an oil-free air compressor.

[0009] Furthermore, the air filter is filled with an adsorbent for adsorbing compressed gas particles, oil and harmful gases generated by the oil-free air compressor (1).

[0010] Furthermore, the adsorbent is activated carbon.

[0011] The beneficial effects achieved by the present invention are: Compared with the prior art, the present invention uses air quality sensors and oxygen concentration sensors to collect oxygen data in compressed air and oxygen cabins respectively, and accordingly, transmits the detection data to the air quality monitoring system and oxygen concentration monitoring system; the air quality monitoring system and oxygen concentration monitoring system respectively detect the quality and oxygen concentration of compressed air in real time and transmit the detection results to the control system; the control system is connected to the air intake electric regulating valve and the exhaust electric regulating valve, and the flow rate of the gas introduced is adjusted according to the detected air quality and oxygen concentration data. After multiple feedback adjustments, the gas content in the cabin is finally achieved to meet the standard, ensuring the quality of treatment and meeting the comfort requirements of the people in the cabin. At the same time, the control system can detect faults in time by real-time monitoring of gas data changes, ensuring the stability and safety of the oxygen cabin. Therefore, the present invention has the advantages of comprehensive monitoring, real-time monitoring, timely response, and ensuring medical quality. BRIEF DESCRIPTION OF THE DRAWINGS
