Description
Technical field
The present invention relates to medical medical instruments field, and in particular to one kind can survey gasbag pressure trachea cannula.
Background technology
Clinic be expert at endotracheal intubation when, the elastic of air bag need to be suitable, if airbag aeration amount is excessive, air bag presses through Gao Huiying
Air flue mucous membrane is rung, clinical study results are shown, when air bag is pressed more than 30cm H2O（1cmH2O=0.098KPa）When, mucous membrane capillary
Vascular flow starts to reduce, and when air bag is pressed more than 50cmH2O, blood flow is blocked completely, and tracheal mucosa compressing is more than a timing
Between, the even necrosis of tracheal mucosa ischemia injury will be caused, tracheoesophageal fistula can occur when serious, if on the contrary, airbag aeration
Deficiency, then cause gas leakage, inhale by mistake etc., domestic and international investigation result is shown, most of anesthetists, first aid doctor still use fingers-touch method
Whether micro-judgment airbag aeration is enough, and this often leads to the generation excessively inflated, and gasbag pressure is even as high as 210mmHg
（1mmHg=0.133KPa）Even if the doctor having wide experience is no exception, therefore, it should not use and rule of thumb judge inflation
Fingers-touch method is inflated.
The content of the invention
The invention aims to solve the above problems, and a kind of response quickly provided is accurate, error is small, is easy to grasp
That makees surveys gasbag pressure trachea cannula.
The present invention solves the technical measures that its technical problem is taken：
One kind can survey gasbag pressure trachea cannula, including body and gas tube, and described body one end is provided with air bag, the body
The other end is provided with joint, and one end of the gas tube is arranged in air bag, and the other end of the gas tube is connected with extension tube, institute
State extension tube tail end and be provided with unidirectional valve union, pressure sensor, the side of the pressure sensor are provided with the middle part of the extension tube
Face is connected with signal wire, and the upper end of the signal wire is connected with pressure measuring tie-in.
Above-mentioned one kind can survey gasbag pressure trachea cannula, and described pressure measuring tie-in is that quick pluggable patient monitor pressure measurement connects
Head.
Above-mentioned one kind can survey gasbag pressure trachea cannula, and described pressure sensor is silicon pressure type pressure sensor, and with
Extension tube tube chamber, gas tube tube chamber communicate.
Above-mentioned one kind can survey gasbag pressure trachea cannula, and described body uses the PVC material without DEHP to form, described
Air bag uses the TPU sacculus with biocompatibility.
The possessed compared with prior art beneficial effect of the present invention is：The pressure measurement trachea cannula uses miniature high-precision pressure
Force snesor, its feature are that the speed of response is fast, and error is small, anti-interference, safe low-wound, can be observed in real time with fast accurate
To the situation of change of gasbag pressure, the defects of common trachea cannula can not monitor human airway pressure is compensate for, the pressure measurement tracheae
Cannula design is disposable, effectively prevent the risk of cross-reference inadvertent contamination.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention
Wherein：1st, body 2, gas tube 3, air bag 4, joint 5, extension tube 6, unidirectional valve union 7, pressure sensor 8,
Signal wire 9, pressure measuring tie-in.
Embodiment
One kind can survey gasbag pressure trachea cannula, including body 1 and gas tube 2, and described one end of body 1 is provided with air bag 3, institute
The other end for stating body 1 is provided with joint 4, and one end of the gas tube 2 is arranged in air bag 3, the other end of the gas tube 2 with
Extension tube 5 connects, and the tail end of extension tube 5 is provided with unidirectional valve union 6, and the middle part of extension tube 5 is provided with pressure sensor 7,
The side of the pressure sensor 7 is connected with signal wire 8, and the upper end of the signal wire 8 is connected with pressure measuring tie-in 9, described survey
Crimp head 9 is quick pluggable patient monitor pressure measuring tie-in, and described pressure sensor 7 is silicon pressure type pressure sensor, and with prolonging
The tube chamber of long tube 5, the tube chamber of gas tube 2 are communicated, and described body 1 is formed using the PVC material without DEHP, and the air bag 3 uses
TPU sacculus with biocompatibility.
The present invention is when it is implemented, inserted trachea cannula by clinical routine flow, by patient monitor and pressure measuring tie-in 9
It is directly connected to, then by unidirectional valve union 6 to the gas injection of air bag 3, you can pass through the pressure that patient monitor is observed in air bag 3 at any time and become
Change, prevent from excessively inflating, during whole use, can also observe pressure change in air bag 3 at any time, meet needed for clinic.
Pressure measurement trachea cannula of the present invention shows to have the advantage that by clinical trial：The pressure measurement trachea cannula speed of response
It hurry up, error is small, anti-interference, the low damage of safety, can observe the situation of change of airway pressure in real time with fast accurate, integrated
Design facilitates the operation of medical care and the constraint interference of cable, there is provided the data of safety and precise, important doctor is provided for clinical treatment
Learn and judge information, the method for improving Scientific Treatment reduces the generation of medical-risk accident, effectively avoids cross-reference unexpected
The risk of infection, the defects of common trachea cannula can not monitor human airway pressure in real time is overcome, meets clinical medicine pair
The needs of pressure-relief vent management.
Particular embodiments described above, the purpose of the present invention, technical scheme and beneficial effect are carried out further
Describe in detail, should be understood that the specific embodiment that the foregoing is only the present invention, be not intended to limit the invention,
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., it should be included in the present invention's
