How to ensure the oxygen concentration and flow rate of Medical Oxygen Generator?
Release Time : 2024-11-07
Medical Oxygen Generator plays a vital role in the medical field. The stability of its oxygen concentration and flow rate is related to the treatment effect and safety of patients.
1. Guarantee at the technical principle level
Medical Oxygen Generator mostly uses pressure swing adsorption (PSA) technology or membrane separation technology. Taking pressure swing adsorption technology as an example, it uses the difference in the adsorption capacity of molecular sieves for different gases to separate oxygen. In this process, it is very important to accurately control the pressure change of the adsorption tower. Through the precise pressure regulation system, it is ensured that the molecular sieve adsorbs impurity gases such as nitrogen at a suitable pressure to enrich oxygen. At the same time, strict control of the adsorption and desorption time can ensure that high-concentration oxygen can be stably produced in each cycle. For membrane separation technology, high-quality separation membranes are the key. These membranes have special selectivity, allowing only specific gases such as oxygen to pass through, and the stability of their performance can ensure the continuous and effective separation of oxygen and maintain a stable oxygen production concentration.
2. Quality and design of equipment components
The quality of the compressor of the oxygen generator affects the intake volume and pressure. A high-quality compressor can stably provide the system with sufficient and appropriate air source at appropriate pressure. The design and material of the gas pipeline should not be ignored. High-quality pipeline materials can prevent gas leakage and impurities from mixing, ensuring the stability of the gas during transmission. In addition, the accuracy of the flow control valve is of great significance for controlling the oxygen flow. Advanced flow control valves can accurately adjust the oxygen flow according to the set value, and can accurately meet both low and high flow requirements. Moreover, the sensors in the equipment are the "eyes" to ensure the oxygen concentration and flow. The oxygen concentration sensor must have high sensitivity and accuracy, monitor the oxygen concentration in real time, and feedback the signal to the control system for adjustment once the concentration deviates from the set range. The same is true for the flow sensor, which accurately measures the oxygen flow to ensure that it meets the requirements for medical use.
3. Maintenance and calibration
Regular maintenance of the Medical Oxygen Generator is a necessary measure to ensure its performance. Cleaning the molecular sieve in the adsorption tower, checking whether the pipeline connection is tight, calibrating the sensor and other operations can keep the equipment in the best working condition. At the same time, calibrating the oxygen concentration and flow rate according to standard gas can ensure that the device display value is consistent with the actual value, thereby accurately providing patients with the required concentration and flow of oxygen during use, ensuring medical safety and quality.
