Furthermore, the inner sleeve (1), the snap ring (2), the outer tube (3) and the outer tube sleeve (4) are all made of metal materials.

The utility model has the beneficial effects that: the effect of gradual stifled pipe can be solved with a device, and when airway secretion such as sputum scab glued in interior sleeve pipe, interior sleeve pipe change was very convenient, selects for use metal material, can accomplish disinfection, multiplexing, and it is low to take place exogenous infection probability. The design of the bayonet of the snap ring enables the pipe blocking device to be fixed quickly and stably. The outer pipe is matched with the outer pipe sleeve in a rotating mode through threads, the operation is simple, and the situations of cough-out of a pipe blocking device and the like are avoided. The utility model has reasonable structure and can be widely applied to the technical field of medical instruments.
