Description

Technical Field

[0001] This utility model relates to the field of ventilator pressure regulation technology, specifically a ventilator pressure regulating valve. Background Technology

[0002] The pressure regulating valve is a key component of a ventilator, its main function being to regulate and stabilize the gas pressure delivered to the patient, ensuring comfortable and safe breathing. The valve senses and adjusts gas pressure through a sophisticated internal mechanical structure. When the gas pressure generated by the ventilator is too high, the valve automatically reduces the output pressure to prevent excessive pressure injury to the patient; conversely, when the pressure is too low, the valve increases the output pressure to ensure the patient receives sufficient oxygen.

[0003] However, existing ventilator pressure regulating valves have the following drawbacks:

[0004] (1) The existing pressure regulating valve of the ventilator has weak maintenance function. When in use, the device may malfunction after a long period of use, which may cause the problem of inaccurate pressure regulation.

[0005] (2) The existing pressure regulating valve of the ventilator has a weak sealing function. When the device is used, it needs to be connected to an external oxygen cylinder. When the external oxygen cylinder is connected, air leakage may occur, causing oxygen leakage. Utility Model Content
