Description

Cannula joint and closed sputum aspirator Technical Field The utility model relates to the technical field of medical instruments, in particular to an intubation joint and a closed sputum aspirator tube adopting the intubation joint. Background Clinically, for patients who cannot remove phlegm or cough and have dyspnea, artificial sputum aspiration is required. And accordingly the tubing set needs to be docked with the respiratory mask that the patient often wears via the cannula fitting. The existing common pipeline butt joint generally adopts an interference fit plugging mode, so that the situation of loosening easily occurs. Disclosure of utility model The technical problem to be solved by the embodiment of the utility model is to provide the cannula joint which is convenient and firm to butt and can prevent unexpected loosening. The embodiment of the utility model aims to solve the technical problem of providing the closed sputum aspirator which is convenient and firm to dock and does not influence the use of a suction catheter. In order to solve the technical problems, the embodiment of the utility model provides an intubation joint, which comprises a joint main body and an intubation joint, wherein one end of the intubation joint is provided with an external port for butting an external pipeline, the other end of the intubation joint is provided with an intubation tube for communicating with the joint main body, and the joint main body is provided with an inoculation tube for inserting the intubation tube; The side wall of the insertion pipe is provided with a locking block, the inner side wall of the insertion pipe is provided with a locking channel, the locking channel comprises an insertion channel for the insertion of the locking block and a rotating channel for the circumferential movement of the locking block, and the locking block enters the rotating channel along the insertion channel; The locking piece is provided with a clamping part, and a feedback part for blocking the movement of the clamping part is arranged at a preset position of the rotating channel, so that the movement of the locking piece is blocked through the combination or contact of the clamping part and the feedback part.
