Background
The artificial airway is an established gas channel which is formed by inserting a catheter into the trachea through the mouth/nose or a tracheotomy position, can correct the anoxic state of a patient and improve the ventilation function. The trachea cannula in the current market mainly comprises a tube body, a cuff, a joint, an indicating air bag and an inflation tubeAnd the tracheal intubation is provided with a cuff, so that the device aims at closing an airway, fixing a catheter, ensuring the supply of tidal volume and preventing oropharyngeal secretions from entering the lung, thereby reducing the occurrence of complications such as lung infection and the like. The cuff pressure range of 20-30cmH is set by the doctor after the conventional tracheal intubation according to the experience2O, this setting is an empirical setting range and does not accurately set the optimal cuff pressure value for the individual patient. If the cuff pressure is too low, air leakage of an air passage can occur, the ventilation of a breathing machine is affected, and pathogenic bacteria at the oropharynx part freely enter the lower respiratory tract; and the excessive inflation of the cuff can cause throat pain, airway mucosa ischemia necrosis and even complications such as tracheoesophageal fistula and the like. Because of the many factors that affect cuff pressure, finding and maintaining an optimal cuff pressure minimizes the incidence of ventilator-associated pneumonia (VAP).
For this reason, there is a patent publication No. CN210644792U in china that discloses an endotracheal tube with a pressure sensor, which can solve the above problems, but it cannot close the airway with the most suitable cuff pressure value, and is not suitable for users with different airways. Therefore, the applicant has designed a tracheal intubation for preventing airway pressure injury, which accomplishes airway occlusion with the most appropriate cuff pressure.

Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 1, the trachea cannula for preventing airway pressure injury comprises a tube body 100, a first cuff 200a, a second cuff 200b and a pressure sensor 300.
The tube 100 is used to be placed in the airway a, and the tube 100 is made of a flexible hose. The first cuff 200a and the second cuff 200b are axially arranged on the tube body 100 at intervals, the first cuff 200a and the second cuff 200b are connected with an external air source through a first inflation tube and a second inflation tube, and as in the prior art, the first inflation tube and the second inflation tube are provided with one-way valves, and the external air source is an air pump or a syringe. An external gas source delivers first and second inflation tubes into the first and second cuffs 200a, 200b, enabling the first and second cuffs 200a, 200b to occlude the airway a.
The pressure sensor 300 is disposed on the outer wall of the tubular body 100 between the first and second bladders 200a and 200b, and the pressure sensor 300 is connected to a pressure display 400. The pressure sensor 300 in this embodiment is embedded in the outer wall of the pipe body 100, the detection end 310 of the pressure sensor 300 is flush with the outer wall of the pipe body 100, the pressure sensor 300 is connected to the pressure display 400 through a signal line 300a, and the signal line 300a extends to the outside along the inside of the pipe wall.
The protection portion 320 is disposed on the tube wall of the front end surface of the pressure sensor 300 in this embodiment, the protection portion 320 includes an arc protection portion 321 integrally formed with the tube body, and the height of the arc protection portion 321 is slightly higher than the surface of the tube body, so as to further prevent the pressure sensor 300 from scratching the inner wall of the airway.
The utility model discloses during the use, at first put into airway a with body 100 in, inflate first cover bag 200a (aerify certain pressure value, can be clinical medicine's pressure high limit value) through external air supply, second cover bag 200b keeps the uninflated state, then the switch-on breathing machine ventilates airway a, pressure sensor 300 detects airway a pressure on every side and fluctuates along with breathing, pressure sensor 300 passes through information line 310 with information transmission to pressure display 400, pressure display 400 shows the pressure fluctuation curve. Then, the second cuff 200b is slowly inflated by an external air source, the airway pressure around the baroreceptor 400 is slowly reduced due to the gradual inflation and occlusion of the second cuff 200b, and the pressure fluctuation is gradually smoothed out on the pressure display 400. When the second cuff 200b is inflated just enough to completely block the airway a, the pressure sensor 300 is completely blocked between the first cuff 200a and the second cuff 200b, the pressure of the airway a cannot be sensed, the pressure fluctuation of the pressure display 400 is a straight line, the second cuff 200b is in a state of the minimum cuff pressure capable of blocking the airway a, then the first cuff 200a is deflated, and the second cuff 200b performs the function of blocking the airway a.
The utility model discloses can confirm the most suitable cover bag air flue shutoff pressure through the wave form on the pressure display 300, avoid pressure too high or low excessively, all usable to the user of different air flues, can prevent effectively that the air flue from crushing.
