[0002] Currently in the field of first aid for medical patients, in order to ensure the patient's aerobic breathing, oxygen inhalers are used to provide oxygen therapy for patients with hypoxia who are unable to breathe independently.

[0003] When the catheter plug of a traditional oxygen inhaler is connected to the oxygen inhalation catheter, a nested connection is mainly adopted. This connection method is convenient, but the oxygen inhalation catheter nested on the surface of the catheter plug has no fixed structure design. During the oxygen inhalation process, when the oxygen inhalation catheter is subjected to external tension, it is easy to cause the connection between the oxygen inhalation catheter and the catheter plug to loosen, thereby causing oxygen leakage and affecting oxygen inhalation. For this reason, we designed an oxygen inhaler to solve the above-mentioned problems. Utility Model Content

[0009] In the above-mentioned oxygen inhaler, a connecting block is fixedly provided at the bottom of the airway tube, an annular interface is provided at the bottom of the connecting block, and a fixing ring is fixedly provided at the top of the oxygen filter block, and the fixing ring is nested and connected with the annular interface.

[0026] Specifically, the threaded push rod 16 is rotated to push the semicircular block 18 to move, so that the arc-shaped pressure strip 19 on the surface of the semicircular block 18 is pressed into the inside of the arc-shaped pressure groove 20 opened on the surface of the oxygen inhalation catheter 14, thereby fixing the oxygen inhalation catheter 14 and improving the firmness of the connection between the catheter plug 7 and the oxygen inhalation catheter 14.
