The core of the simple respirator, as an important piece of equipment in first aid, lies in the precise collaboration of its six-valve system. These six valves are: anti-return valve, exhalation valve, inhalation valve, inlet valve, exhaust valve and pressure gauge. The anti-return valve ensures that the gas flows in the right direction to avoid contamination; the exhalation valve controls the discharge of gas and the entry of fresh air; and the suction valve is responsible for the introduction of air. The inlet and exhaust valves manage the inflow of air and the outflow of carbon dioxide and water vapor, respectively, to keep the internal gases clean. A pressure gauge monitors the patient's respiratory status and maintains normal breathing by adjusting the pressure.
The effectiveness of these valves has a direct impact on the performance of the rebreather, and problems with any individual valve can affect the overall function. It is vital to check the valves regularly. First, check the appearance of the valves to make sure there are no cracks or damage. Next, test the flexibility and sealing of the valves to ensure that the springs and jackets are working properly and that inhalation and exhalation times are accurate. Finally, check pressure gauge readings and that the exhaust valve is clear to ensure accurate data and no blockages. Always operate the valve cleanly and use specialized tools to avoid damage and risk of infection. Once abnormal valves are found, be sure to replace or repair them promptly to ensure the proper operation of the emergency equipment.
Maintaining the valves of your rebreather is a critical part of ensuring its proper functioning. They should be kept clean to prevent bacterial growth and stored properly to avoid physical damage to the valves. Replace valves regularly, clean and sanitize them, and follow the manufacturer's maintenance instructions. Also, protect against static electricity, moisture, and shock, and follow operating instructions for maintenance. Any damaged or broken valves should be dealt with promptly so as not to jeopardize the life of the patient.
