The technical problems to be solved in the utility model is：There is provided a kind of closure conveniently and be capable of the tracheal catheter lid of pressure release.
Technical solution for the use that solves the above problems is：Tracheal catheter lid includes sealing cover, closure shell resilient sleeve, lets out
All there is the closure shell of opening at pressure valve and hollow and both ends；Closure shell includes the closure shell medial segment of insertion tracheal catheter
With the closure shell segmentum laterale being exposed at outside tracheal catheter；Closure shell resilient sleeve is sleeved on outside closure shell medial segment；Sealing cover
It is connected by flexible connecting member with closure shell segmentum laterale, the opening of sealing cover closure cap hull outside section can simultaneously be opened；Let out
Pressure valve is arranged on closure shell segmentum laterale, and when closure shell internal pressure raises, relief valve can open so that closure shell
Body inner space is connected with outside.
It is further：Tracheal catheter lid includes sealing cover resilient sleeve, and sealing cover includes close inside insertion closure shell
Medial segment is covered, sealing cover resilient sleeve is sleeved on outside sealing cover medial segment.
It is further：Pressure relief device is one-way valve.
It is further：Pressure relief device includes diaphragm seal and spring, and diaphragm seal venthole is provided with diaphragm seal；Outside housing
Diaphragm seal step and spring step are provided with the section of side, closure shell ventilation is both provided with diaphragm seal step and spring step
Hole, the space between diaphragm seal step and spring step are pressure relief device chamber；Diaphragm seal and spring are located at pressure relief device intracavitary, bullet
Spring is supported on spring step and diaphragm seal is bonded with diaphragm seal step, diaphragm seal step close encapsulation piece venthole.
The beneficial effects of the utility model are：Closure shell medial segment is filled in tracheal catheter can close tracheal catheter,
It is easy to operate.When patient coughs, closure shell internal pressure increase, pressure relief device can open pressure release, avoid pressure excessive
Caused tracheal catheter takes off pipe.
