A kind of cannula for tracheotomy

Abstract

The invention provides a sleeve used for the tracheotomy, relating to medical apparatus and instruments, aiming at solving the technical problem that the existing sleeve enables a patient to have the sensation of asphyxia, ventilation difficulty and sound production difficulty. An outer sleeve body of the sleeve is an arc-shaped tube, one end of the outer sleeve body is provided with an annular flange, the other end of the outer sleeve body is provided with a tapered cut; a fixing wing is arranged on the outer sleeve body, and fixing belts are arranged in through holes in the two ends of the fixing wing; an inner sleeve body is sleeved by the outer sleeve body and is an arc-shaped tube, one end of the inner sleeve body is provided with a flange, a clamp groove is formed in the flange and matched with a clamp pin of the fixing wing, external threads are arranged in front of the flange, and the external-cambered-surface side wall of the other end of the inner sleeve body is provided with a tapered cut; a tube core penetrates through the cavity of the inner sleeve body, and is composed of a plugging cap, a connecting rod and a guide head, and the inner wall of the plugging cap is provided with internal threads matched with the external threads of the inner sleeve body; and a hollow channel is formed in the tube core. The sleeve is used for the clinical tracheotomy, and has the advantages that the sensation of asphyxia of the patient can be alleviated, the separating seldom occurs, the sound production is easy during the sound production training, the design is reasonable, the connection is reliable, and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a sleeve tube for tracheotomy. Background technique [0002] At present, there are two types of tracheal tubes used in tracheotomy clinically. One is disposable tracheal tubes, which cause waste because they cannot be reused; the other is metal tracheal tubes, which can be Cleaning, disinfection and replacement, can be used for a long time. Metal tracheal tubes are widely used in clinical tracheotomy. [0003] The metal tracheal cannula of the prior art has the following disadvantages: 1. The tube core of the catheter is a solid body, which will cause a sense of suffocation to the patient during the process of being sent into the trachea; After changing the body position or raising the head and lowering the head, it will be difficult to enter the sputum suction tube, and even the ventilation is not smooth; 3. During the vocalization training process, the blocking cap wi...
