Description
Technical field
The present invention relates to technical field of medical equipment, particularly a kind of endotracheal catheter with infrared facility and bite-block
Device.
Background technology
Tracheal catheter is to be used for a kind of anaesthetic apparatus of Patients with Mechanical Ventilation in general anesthesia.In general anesthesia, anesthesia
Doctor is needed the front end of tracheal catheter being inserted into tracheal strips through patient oral cavity, and the rear end of tracheal catheter is connected into breathing
Oxygen is sent in Patients with Lung and carries out mechanical ventilation by machine, lung ventilator by tracheal catheter, to maintain the breathing in patient's art.Institute
To ensure that tracheal catheter front end is located at tracheal strips for ensureing that vital sign is particularly significant in patient's art.But in surgical procedure,
The position of tracheal catheter often changes.
Because tracheal catheter is once influenceed by operation technique in operation, patient body position influences, even anticipated
Outer drawing etc. may result in tracheal catheter and insert too deep, excessively shallow or abjection tracheae, and this will be had a strong impact in patient's art
Mechanical ventilation, is threatened to patient vitals' safety belt.
The common method of existing monitoring tracheal catheter position is the quarter for visually observing tracheal catheter at patient's front tooth
Degree, but this method can not accomplish real-time monitoring.And in some operations, the face of patient can be covered by the sterile list of operation
Cover and the scale of tracheal catheter can not be observed.Although the front end of some current tracheal catheters can be observed at any time with camera
The position of tracheal catheter, but this tracheal catheter involves great expense, and its front end camera also easily by endotracheal point
Secretion is blocked and hinders observation.
Meanwhile, the problem of patient teeth bites tracheal catheter is often occurring in surgical procedure.
Therefore, generally bite-block is fixed at patient's front tooth together with tracheal catheter, for aiding in the fixation of tracheal catheter,
Prevent tracheal catheter from being bitten and be shifted in surgical procedure by tooth.And the position of tracheal catheter is monitored using bite-block
Put most beneficial for the real-time variation for finding tracheal catheter position, this not only enriches the function of bite-block, and can make anesthesia
Doctor has found the change of tracheal catheter position in time, improves the security of anesthesia.And at present still without a kind of monitoring means
The position of tracheal catheter can in real time be included referring to for Anesthetist on monitor screen.
