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.
