Abstract

The invention relates to an anesthesia breathing mask. The anesthesia breathing mask comprises a rigid mask body, a soft annular sealing part used for covering the mouth and the nose of a user is arranged on the mouth edge of the open end of the rigid mask body, an air supply connecting pipe is at least arranged on the mask body, a catheter seat is arranged on the mask body, a central hole of thecatheter seat serves as a rigid pore passage enabling the inner face and the outer face of the mask body to communicate, a soft diaphragm of an annular-strip-shaped structure is arranged in the rigidpore passage, the periphery of the soft diaphragm is fixed to the inner wall of the rigid pore passage in a closed mode, an annular filling cavity is defined by a rigid inner wall area, between the upper edge and the lower edge of the diaphragm, in the rigid pore passage and the diaphragm, the outer surface of the diaphragm arches towards the center of the central hole and forms a sealing fit holeallowing a catheter to penetrate, a connecting hole allowing liquid or gas in the cavity to communicate with the outside is formed in the side wall of the filling cavity, and a ventilation connectingpipe communicating with the outside is connected to the connecting hole.

Description

technical field [0001] The invention relates to a medical device, in particular to an anesthesia breathing mask. Background technique [0002] Painless fiberoptic bronchoscopy has become an inevitable development trend. Due to the sharing of the patient's airway, oxygen supply for anesthesia is difficult. At present, all endoscopic examinations are performed under general anesthesia without intubation. Once such patients suffer from respiratory depression, the risk of hypoxia is extremely high, and there is no other better solution in clinical practice. In clinical anesthesia work, in order to successfully complete the whole body Fiberoptic bronchoscope-guided endotracheal intubation under anesthesia often uses a mask to assist ventilation to ensure the safety of the patient during the operation. The hole diameter of conventional masks currently used is fixed, and different clinical conditions or different patients may use various endoscopes with different diameters for exa...
