Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti - detachment clamping sleeve for a breathing tube and an anesthesia ventilator. Background Art

[0002] In modern clinical medicine, as an effective means to artificially replace the function of autonomous ventilation, anesthesia ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first - aid resuscitation, and play a very important role in the field of modern medicine. An anesthesia ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the lives of patients.

[0003] During the normal use of an anesthesia ventilator, a breathing tube is used to connect to the patient's nasal cavity and oral cavity to form a passage, enabling the patient to breathe smoothly. The other end of the breathing tube is connected to the anesthesia ventilator by means of plug - in connection. The existing installation method simply docks by using frictional resistance. During use, if due to operational errors or movements, etc., the problem of the breathing tube falling off is likely to occur, seriously threatening the health and life of the patient.
