Description

Technical Field

[0001] The utility model relates to the technical field of medical oxygen regulating valve structures, in particular to a medical oxygen regulating valve capable of automatically adjusting flow. Background Art

[0002] ‌Medical oxygen regulating valves are key components in medical equipment used to control and regulate oxygen flow. Medical oxygen regulating valves are mainly used to control and regulate oxygen flow to ensure that patients inhale an appropriate amount of oxygen. They are widely used in hospitals, clinics and other medical institutions. Automatically regulated medical oxygen regulating valves usually use electronic flow meters or pressure sensors and other devices to automatically adjust the oxygen flow rate according to preset parameters to ensure the stability and accuracy of oxygen supply. Manually regulated medical oxygen regulating valves require medical staff to manually rotate the control lever or knob to adjust the oxygen flow rate according to the patient's specific needs. Although this method requires manual operation, it may be more flexible and convenient in some cases.

[0003] Existing medical oxygen regulating valves have certain disadvantages when used. When opening and closing the valve core of a traditional medical oxygen regulating valve, whether manually rotating the control lever or using an electronic control system to switch the valve core, the screw on the valve core is controlled. The screw has an unlimited position structure. When the screw rotates accidentally, the position of the valve core is easily changed, and the oxygen flow rate will change, which is not conducive to the delivery of oxygen. Utility Model Content
