Description

Trachea cannula with body temperature detection probe

Technical Field

The invention relates to the technical field of medical instruments, in particular to a tracheal cannula with a body temperature detection probe.

Background

The technology of placing a special endotracheal tube into the trachea through the glottis is called trachea intubation, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.

When the trachea cannula is used, the air sac is inflated to seal the air passage, so that mechanical ventilation is facilitated and aspiration is prevented. In clinical, the gasbag aerifys excessively and can cause local trachea softening, mucosa damage trachea esophagus fistula etc. even, the gasbag is aerifyd inadequately and can lead to oropharynx secretion and regurgitation thing mistake to inhale the lower respiratory tract and lead to breathing machine correlation pneumonia, consequently, need be with the pressure control in the gasbag in certain within range, both avoid the gasbag internal pressure too high, it is too low to avoid the gasbag internal pressure too, however when using trachea cannula, human lung exhales and inhales and all can change lung pressure size, pressure in the trachea also can follow the change, make the outside pressurized size of gasbag also can follow the change, can lead to appearing the gap between intermittent type nature gasbag outer wall and the endotracheal wall.

Application number is CN 213491314U's a endotracheal tube with monitoring body temperature function is equipped with the recess at the surface of cover bag, the bottom of recess is fixed with the body temperature probe, the purpose of realizing body temperature measurement through body temperature probe and the contact of human trachea wall, but in the in-service use process, can appear the gap between gasbag outer wall and the endotracheal wall, it is gapped between the surface of body temperature probe just and the endotracheal wall if, in addition the hot-air of exhaling passes through the clearance business turn over with inspiratory cold air when the patient breathes, the air flow on the surface of body temperature probe can accelerate, often can make patient's body temperature measure inaccurately, still can cause medical accident under the serious condition, influence patient life safety.
