Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

An endotracheal tube with a balloon visual pressure measuring device as shown in fig. 1 to 3 comprises a tube body 100 having an insertion end 110 for inserting into the respiratory tract of a patient, and a balloon 200 capable of inflating by inflation is annularly arranged on the outer side wall of the insertion end. To which is connected a Y-shaped gas tube 300 having a first branch tube 310 and a second branch tube 320 in gas phase communication therewith. Wherein, the first branch pipe is connected with an air bag inflating assembly 400 which adopts a general structure in the prior trachea cannula, and the second branch pipe is connected with a visual pressure measuring device 500. Specifically, this visual pressure measurement device includes an opaque pressure-measuring pipe 510, and the pressure-measuring pipe is the cylindricality, and it can observe the window 511 of the inside condition of pressure-measuring pipe to fit with a contraceptive ring at the surface of pressure-measuring pipe. A marker post 520 is slidably disposed in the pressure measuring tube and divides the interior space of the pressure measuring tube into a first air chamber 512 and a second air chamber 513. The first air chamber is not communicated with the second branch pipe and is filled with gas in advance, so that the first air chamber generates pressure change similar to a spring when being compressed. And the second air chamber is communicated with the air bag through a second branch pipe. When the pressure in the air bag changes, the pressure is led into the second air chamber through the Y-shaped trachea, and the mark column in the second air chamber is pressed to move towards the first air chamber. It should be noted that the surface of the identification post is surrounded by three circles of identification circles 521 with different colors. In the removal in-process, the sign circle that the window observed on the sign post changes, when the window observed one of them representative pressure suitable sign post, medical personnel can stop aerifing in the gasbag, and the gasbag can play the effect of sealing the clearance between trachea cannula and the respiratory track this moment, can avoid appearing that the gasbag acts on the too big appearance that leads to the pressure nature wound of pressure of respiratory track inner wall again.

As a further improvement of the above embodiment, the meaning of the mark ring on the mark post can be understood more intuitively. The three circles on the post 520 are red, green, and blue in color, respectively. Wherein, red represents that the air bag pressure is too high, green represents that the air pressure is proper, and blue represents that the air pressure is too low. Therefore, the state of the air bag is corresponded to the mark circle with the color when the mark circle appears in the window. The red, green and blue mark rings are arranged in sequence from one end of the mark column far away from the first air chamber to one end of the mark column close to the first air chamber.

As a further improvement of the above embodiment, in order to be more intuitive and easy to understand, the three circles of identification rings on the marking column are respectively provided with the identification words 522 corresponding to the identification rings. Specifically, the red identification ring is provided with a character of 'overlarge pressure', the green identification ring is provided with a character of 'proper pressure', and the blue identification ring is provided with a character of 'undersize pressure'.

As a further improvement of the above embodiment, slight variations in the pressure of the bladder may occur to suit different patients due to differences in patient constitution. But to enable adaptive adjustment. The pressure measuring pipe is also provided with a first inflation pipe 514 communicated with the first air chamber, and the first inflation pipe is screwed with a second inflation pipe 530. A one-way valve 540 is disposed in the second inflation tube. The one-way valve is communicated with the first air chamber from the outside in one way. When the pressure of the air bag needs to be raised during operation, the medical staff inserts the end of the disposable injector into the second inflation tube and injects air into the first air chamber. When the pressure of the air bag in operation needs to be reduced, the medical staff unscrews the second inflation tube, and the gas in the first air chamber is slowly released from the gap between the first inflation tube and the second inflation tube.
