To achieve precise control of oxygen concentration in a single hyperbaric oxygen chamber, it is the result of the coordinated work of multiple technologies and equipment, involving multiple links such as gas supply, monitoring feedback, and intelligent control. The core lies in ensuring that the oxygen ratio in the chamber is stable within a safe and effective range through precise system design to ensure the treatment effect and safety of the user.
First of all, the gas supply system is the basis for precise control of oxygen concentration. Single hyperbaric oxygen chambers are usually equipped with professional oxygen and compressed air supply equipment. The source of oxygen is mostly medical-grade oxygen cylinders or oxygen concentrators, which provide high-purity oxygen; compressed air is generated by air compressors to dilute the oxygen concentration. Oxygen and compressed air are mixed in different proportions through precise gas mixing devices to obtain gas of the required concentration. For example, according to treatment needs, pure oxygen may need to be mixed with air into a mixed gas of a certain proportion to avoid the risk of excessive oxygen concentration.
The flow control device plays a key role in regulating oxygen concentration. The gas flow in the chamber needs to be adjusted in real time according to the treatment stage and the needs of the user. The high-precision gas flow meter monitors the input flow of oxygen and compressed air and feeds the data back to the control system. When the oxygen concentration needs to be increased, the control system will increase the oxygen input flow rate and reduce the compressed air flow rate accordingly; conversely, when the oxygen concentration needs to be reduced, the reverse adjustment is performed. This dynamic flow adjustment can keep the oxygen concentration within the set range at all times.
Pressure regulation is closely related to oxygen concentration control. During the use of a single hyperbaric oxygen chamber, the pressure inside the chamber will be higher than the external atmospheric pressure. And the change in pressure will directly affect the stability of the oxygen concentration. The cabin is equipped with a pressure sensor to continuously monitor the pressure value inside the cabin. When the pressure fluctuates, the control system will synchronously adjust the gas input to ensure that the oxygen concentration still meets the requirements under different pressure conditions. For example, in the boost stage, it is necessary to adjust the input of oxygen and compressed air at the same time to ensure that the oxygen concentration will not deviate while the pressure rises.
Oxygen concentration monitoring equipment provides real-time feedback for precise control. Oxygen concentration sensors are installed in the cabin, which can quickly and accurately detect the oxygen content in the gas in the cabin. The sensor transmits the detected data to the control system in real time, and the control system compares the actual oxygen concentration with the preset value. Once the actual oxygen concentration deviates from the set range, the control system will immediately start the adjustment mechanism to restore the oxygen concentration to normal levels by adjusting the gas flow or mixing ratio. This closed-loop feedback system greatly improves the accuracy and timeliness of oxygen concentration control.
Intelligent control system is the core of achieving precise control of oxygen concentration. The intelligent control system equipped with modern single hyperbaric oxygen chamber integrates advanced algorithms and programs. Operators can set parameters such as oxygen concentration, pressure and time required for treatment through the control system. The system will automatically coordinate various links such as gas supply, flow control and pressure regulation according to the preset parameters. At the same time, the control system also has fault diagnosis and alarm functions. Once the oxygen concentration control is abnormal, it will immediately sound an alarm and take corresponding protective measures, such as automatically cutting off the gas supply or starting the emergency procedure.
In order to ensure the reliability of oxygen concentration control, equipment maintenance and calibration are also essential. Key equipment such as oxygen concentration sensors, gas flow meters and pressure sensors should be calibrated and maintained regularly to ensure the accuracy of their detection and control. At the same time, the gas supply pipeline should be checked to prevent leakage or blockage, which will affect the normal input and mixing of gas. Only by ensuring that the equipment is always in good operating condition can the precise control of oxygen concentration be achieved continuously.
Professional training and standardized operation of operators are also important factors to ensure precise control of oxygen concentration. Operators need to be familiar with the working principle of the hyperbaric oxygen chamber and the oxygen concentration control process, be able to accurately set parameters according to the treatment plan, and closely observe the changes in oxygen concentration during treatment. When encountering abnormal situations, they can quickly judge and take correct treatment measures to ensure a safe and smooth treatment process. Through the close cooperation between personnel and equipment, the oxygen concentration control of the single hyperbaric oxygen chamber can achieve the best effect.
