Anesthesia ventilation catheter for fiberoptic bronchoscopy

Abstract

The invention relates to the technical field of medical treatment, in particular to an anesthesia ventilation catheter for fiberoptic bronchoscopy. The anesthesia ventilation catheter comprises an anesthesia ventilation soft tube; an air intake tube and a air return tube, two A through holes are arranged on outside of the anesthesia ventilation soft tube, and the air inlet tube and the air return tube are fixed to inner sides of the A through holes; a support box, one side of the support box is provided with a safety expansion buffer device; and a box cover plate, the box cover plate is fixed to one side of the opening of the support box, two B through holes are formed in one side of the box cover plate, and the air inlet tube and the air return tube are fixed to inner sides of the B through holes. By arranging the air inlet tube, the air return tube, the support box, the box cover plate, a partition plate, a U-shaped supporting frame, a flow control pipe, a flow control ball, a B threaded rod, a U-shaped support frame, an I-shaped frame, a U-shaped on-off frame, a pressing-off head, a plugging pad, an L-shaped frame, an expansion box, a buffer plate, an adjusting plate and a spring, the anesthesia ventilation catheter has functions of flow control, accurate adjustment, use in multiple modes, safe buffering and the like.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an anesthesia ventilation catheter for fiberoptic bronchoscopy. Background technique [0002] Bronchoscopy is to insert a slender bronchoscope into the patient's lower respiratory tract through the mouth or nose, that is, through the glottis into the trachea and bronchi and more distally, to directly observe the lesions of the trachea and bronchi, and to carry out corresponding examination and treatment according to the lesions. treat. Anesthesia is a reversible functional inhibition of the central nervous system and / or peripheral nervous system produced by drugs or other methods, which is mainly characterized by loss of sensation, especially pain sensation. At present, in many cases, it is necessary to anesthetize the patient first, and then perform a bronchoscopy to relieve the pain of the patient. The current inhalation anesthesia needs to connect one end of the anesthesia v...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the anesthesia ventilation catheter in the prior art, which has a simple structure and single function, can only transport gas anesthetics, and cannot control the flow of gas anesthetics, so when the anesthesia machine breaks down or Unstable, when a large amount of gas anesthetics are discharged, these gas anesthetics will be directly inhaled by the patient, and inhalation of a large amount of gas anesthetics will cause harm to the patient, and there is no shortcoming of stable drug supply function, and a fiberoptic bronchoscope is proposed Check the anesthesia ventilation catheter
