AI Technical Summary

Technical Problem

Existing anesthetic intubation tubes are prone to displacement during use, leading to excessive pressure in the throat. Furthermore, patients may experience adverse consequences if they unconsciously clench their jaws when they wake up unexpectedly.

Method used

An abutment mechanism is provided on the outer cylindrical surface of the anesthesia cannula, including an inflation component and a tightening component. The silicone inflation part is fitted onto the patient's teeth and fixed by inflation through the first inflation line, which reduces pressure on the throat and prevents the patient from unconsciously clenching their upper and lower jaws.

Benefits of technology

It effectively reduces pressure on the throat, prevents patients from unconsciously clenching their jaws when they wake up unexpectedly, and reduces the probability of adverse consequences.

Abstract

The anesthesia cannula for the surgical operation comprises a ventilation hose and an abutting mechanism arranged on the outer cylindrical surface of the ventilation hose, the abutting mechanism is located at the end, close to the outside, of the ventilation hose, and the abutting mechanism comprises an inflation assembly and an elastic assembly fixedly connected with the inflation assembly. The air inflation assembly comprises an air inflation part and a first air inflation line for supplying air to the air inflation part, the air inflation part is provided with an upper tooth socket and a lower tooth socket which are oppositely arranged, the upper tooth socket is provided with an upper abutting face abutting against the upper tooth face and an upper occlusal face making contact with the upper tooth tip end, and the lower tooth socket is provided with a lower abutting face abutting against the lower tooth face and an upper occlusal face making contact with the lower tooth tip end. The lower tooth socket is provided with a lower abutting face abutting against the lower tooth face and a lower occlusal face making contact with the tip end of the lower tooth. According to the anesthesia cannula for the surgical operation, the pressure of the ventilation hose on the throat of a patient can be relieved, and meanwhile the situation that the patient accidentally wakes up to tightly close the upper jaw and the lower jaw in a subconscious mode, and consequently negative effects are caused is avoided.
