Description

Technical Field

[0001] This utility model belongs to the field of hyperbaric oxygen chamber technology, specifically relating to a gas analysis and control device for an oxygen chamber. Background Technology

[0002] In modern medical systems, hyperbaric oxygen therapy is an important treatment method. It uses oxygen and pressurized gas as a medium to treat anaerobic infections, carbon monoxide poisoning, air embolism, decompression sickness, hypoxic-ischemic encephalopathy, traumatic brain injury, and cerebrovascular diseases. Therefore, the quality of the gas source within the hyperbaric chamber directly affects the treatment outcome. The main components of the gas in the hyperbaric chamber come from the source gas and waste gases generated by human activity. Besides being affected by the ambient air at the air inlet, the source gas is also influenced by the air compressor, storage tank, and pressure pipelines. Current hyperbaric chambers control the source gas quality using a single detector, which is labor-intensive, lacks real-time monitoring, and can easily lead to low medical quality and undetected equipment malfunctions. Furthermore, while focusing on the control and monitoring of the source gas, the physiological hygiene and comfort needs of the personnel inside the chamber are neglected. Therefore, designing a gas analysis and control device for hyperbaric chambers is of great significance. Utility Model Content

[0003] To address the aforementioned deficiencies, this utility model aims to provide a gas analysis and control device for oxygen chambers. This device monitors the gas quality inside the oxygen chamber in real time, ensuring a stable gas supply, timely discharge of waste gas, and a comfortable experience for personnel.

[0006] The air compressor is connected to an air filter. The filtered compressed air passes through an air quality sensor and an electric intake regulating valve before entering the oxygen chamber. An air quality sensor is also installed in the oxygen chamber. The air quality sensor collects the air quality data of the filtered air and the air quality data inside the chamber, and then transmits it to the air quality monitoring system.

[0007] The oxygen tank is directly connected to the oxygen chamber to provide oxygen to the oxygen chamber. The oxygen chamber is equipped with an oxygen concentration sensor, which is used to collect oxygen concentration data in the oxygen chamber and then transmit it to the oxygen concentration monitoring system.

[0008] The air quality monitoring system is used to monitor the air quality at the back end of the air filter and inside the oxygen chamber, and transmits the results to the control system; the oxygen concentration monitoring system is used to monitor the oxygen concentration inside the oxygen chamber, and transmits 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 degree of the intake electric regulating valve and the exhaust electric regulating valve.

[0009] Furthermore, there are multiple oxygen concentration sensors, each connected to an oxygen concentration monitoring system.

[0010] Furthermore, the number of oxygen concentration sensors is two.

[0011] Furthermore, the air quality sensor and oxygen concentration sensor each include an audible and visual alarm device.

[0012] Furthermore, the air compressor is an oil-free air compressor.

[0013] Furthermore, the air filter is filled with an adsorbent to adsorb the compressed gas particles, oil, and harmful gases generated by the oil-free air compressor (1).

[0014] Furthermore, the adsorbent is activated carbon.

[0015] The beneficial effects achieved by this utility model are:

[0016] Compared with existing technologies, this invention utilizes air quality sensors and oxygen concentration sensors to collect data on compressed air and oxygen levels within the oxygen chamber, respectively. The detected data is then transmitted to an air quality monitoring system and an oxygen concentration monitoring system. These systems monitor the compressed air quality and oxygen concentration in real time and transmit the results to a control system. The control system connects to an electric intake valve and an electric exhaust valve, adjusting the flow rate of the introduced gas based on the detected air quality and oxygen concentration data. Through multiple feedback adjustments, the gas content within the chamber ultimately meets the standards, ensuring treatment quality and meeting the comfort requirements of the personnel inside. Simultaneously, by monitoring changes in gas data in real time, the control system can promptly detect faults, ensuring the stability and safety of the oxygen chamber operation. Therefore, this invention has the advantages of comprehensive monitoring, real-time monitoring, timely response, and ensuring medical quality. Attached Figure Description

[0022] The air compressor 1 delivers compressed air into the oxygen chamber 6, and an oil-free air compressor is selected to greatly reduce the pollution of hydrocarbons and oil mist during the compression process.

[0023] The air filter 2 is filled with activated carbon of various types. Activated carbon is used to adsorb particulate matter, oil and harmful gases in compressed gas.

[0024] The intake electric regulating valve 4 is used to control the rate and flow of compressed air entering the oxygen chamber.

[0025] The exhaust electric regulating valve 9 is used to control the rate and flow rate of the mixed gas such as compressed air and exhaust gas discharged from the oxygen chamber;

[0026] The gas analysis and control system includes an air quality sensor 3, an air quality monitoring system 5, an oxygen concentration sensor 10, an oxygen concentration monitoring system 8, and a control system 7.

[0027] The air quality sensor 3 samples the compressed air at the rear end of the air filter 2 and into the oxygen chamber 6, and transmits the data to the air quality monitoring system 5; the oxygen concentration sensor 10 samples the oxygen concentration in the oxygen chamber 6 and transmits the data to the oxygen concentration monitoring system 8; the air quality monitoring system 5 monitors the air quality at the rear end of the air filter 2 and in the oxygen chamber 6 in real time, and transmits the results to the control system 7; the oxygen concentration monitoring system 8 monitors the oxygen concentration in the oxygen chamber 6 in real time, and transmits the signal to the control system 7; the control system 7 processes the data signals from the air quality monitoring system 5 and the oxygen concentration monitoring system 8, controls the intake electric regulating valve 4 and the exhaust electric regulating valve 9, and adjusts the gas flow rate in real time to control the air quality in the oxygen chamber 6. Example 1

[0028] The air compressor 1 is connected to the air filter 2. The filtered compressed air passes through the air quality sensor 3 and the intake electric regulating valve 4 in sequence before entering the oxygen chamber 6. The oxygen chamber 6 is also equipped with an air quality sensor 3. The air quality sensor 3 outside the oxygen chamber 6 and the air quality sensor 3 inside the oxygen chamber 6 are respectively connected to the air quality monitoring system 5 to monitor changes in air quality in real time.

[0029] The oxygen tank 11 is directly connected to the oxygen chamber 6 to provide oxygen to the oxygen chamber 6. The oxygen chamber 6 is equipped with an oxygen concentration sensor 10, which is connected to the oxygen concentration monitoring system 8 to monitor changes in oxygen concentration in real time.

Example 2

[0031] This embodiment is based on Embodiment 1. In order to monitor the changes in oxygen concentration in the oxygen chamber 6 more evenly and comprehensively, two oxygen concentration sensors 10 are installed in the oxygen chamber 6. The two oxygen concentration sensors 10 are located at the front and rear sides of the oxygen chamber, respectively, and are connected to the oxygen concentration monitoring system 8. Example 3

[0034] Option 1: When the air quality data collected by the air quality sensor 3 located at the rear end of the air filter 2 is monitored in real time by the air quality monitoring system 5, if the air quality data does not meet the standards, the air quality monitoring system 5 will feed back the results to the air quality sensor 3 and the control system 7.
