Medical tracheostomy cannula

Abstract

The invention relates to a medical tracheostomy cannula. The tracheostomy cannula comprises a main tube, a tracheal air bag and a fixed wing, wherein the main tube is fixed on the fixed wing; the tracheal air bag is arranged outside the main tube and communicates with an inflation flow channel in the tube wall of the main tube; one end of the inflation flow channel in the tube wall of the main tube is connected with a double-channel air bag tube; one end of the double-channel air bag tube is connected with a pressure detection mechanism; the pressure detection mechanism comprises a detection tube, a piston, a spring, an observation window and scale marks; the piston slides in the detection tube through the spring and corresponds to the observation window and the scale marks on the surface of the detection tube; and an exhaust port is formed in the detection tube. The double-channel air bag tube is arranged and connected with an inflation structure, the tracheal air bag and the detection tube, so that the tracheal air bag can be inflated, and meanwhile, the air pressure in the tracheal air bag can be detected; and the structure is simple, reading is convenient, accurate inflation can be achieved, and an air bag pressure gauge does not need to be additionally used for pressure detection.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a medical gas cutting sleeve. Background technique [0002] A tracheostomy is an emergency procedure used to relieve shortness of breath caused by an airway obstruction. For respiratory failure caused by retention of lower respiratory tract secretions (such as craniocerebral trauma, thoracoabdominal trauma, polio, etc.), tracheotomy is an important auxiliary treatment method, and the lower respiratory tract secretions can be sucked out through the tracheotomy tube , thereby improving gas exchange in the lungs. In addition, in order to cooperate with the smooth operation of the mouth, pharynx and other parts, the necessary tracheotomy can prevent blood from flowing down into the respiratory tract and obstruct breathing, so that the respiratory tract will be unobstructed during the operation. [0003] The tracheotomy tube is generally composed of a main tube, a trache...

AI Technical Summary

Problems solved by technology

When using an air bag pressure gauge for operation, only one tracheal air bag in the patient's trachea can be adjusted at a time, and due to its high cost, it is impossible for each patient to be equipped with an air bag pressure gauge, which is very inconvenient to use, so most doctors and nurses Personnel generally use a lot of disposable syringes, but when using disposable syringes to inflate and deflate, the pressure of the tracheal airbag cannot be detected, and the gas pressure can only be judged by pinching the swelling degree of the small airbag by relying on the experience of medical staff. Inflate and deflate again, the operation safety of less experienced medical staff is lower
