Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses strenghthened type trachea cannula. Referring to fig. 1 and 2, the reinforced tracheal cannula comprises a tube body 1, a cuff 2 and an indicating balloon 3, wherein the cuff 2 is sleeved on the outer wall of the tube body 1, the cuff 2 is positioned at one end of the air outlet of the tube body 1, the indicating balloon 3 is fixedly connected with an inflation tube 31, the inflation tube 31 is communicated with the inner cavity of the indicating balloon 3, the inflation tube 31 is arranged on the inner wall of the tube body 1 in a penetrating manner, the inflation tube 31 is fixedly connected with the inner wall of the tube body 1, and one end, far away from the indicating balloon 3, of the inflation tube 31 penetrates out of the tube body 1 and is communicated with the balloon 2. After body 1 inserts patient's trachea, medical staff accessible instructs sacculus ball 3 and gas tube 31 with gaseous leading-in cuff 2 in, makes cuff 2 swell to cuff 2 can butt in patient's endotracheal wall, reduces the tracheal cannula condition that breaks away from patient's trachea in the use, in addition, can also reduce the tracheal cannula's the gas outlet end with the condition of patient's trachea fish tail.

Referring to fig. 2 and 3, the humidity inside the patient's trachea is more directly known to the medical staff. The body 1 is provided with surveys subassembly 4, it includes detecting head 41 and transmission line 42 to survey subassembly 4, detecting head 41 is miniature humidity transducer, fixed slot 11 has been seted up to the outer wall of body 1, fixed slot 11 is located one side that cover bag 2 is close to body 1 income trachea end, detecting head 41 bonds in the cell wall of fixed slot 11, transmission line 42 is connected in the inner wall of body 1, body 1 and transmission line 42 fixed connection in detecting head 41 are worn out to transmission line 42 near the one end of detecting head 41, body 1 and fixedly connected with display screen 5 are worn out to the one end that detecting head 41 was kept away from to transmission line 42. After the tube body 1 is inserted into the trachea of a patient, the probe 41 can monitor the humidity condition in the trachea of the patient in real time, and transmit the measured data to the display screen 5 through the transmission line 42 by an electric signal, so that medical staff can directly know the humidity condition in the trachea of the patient from the display screen 5.

Referring to fig. 2 and 3, the outer wall of the pipe body 1 is provided with the shielding member 6, and the shielding member 6 includes a shielding plate 61, a supporting rib 62, and a choke strip 63. The protection piece 61 is arc-shaped sheet structure, the inner arc surface faces the pipe body 1, and the partial edge of the protection piece 61 is fixedly connected to the outer wall of the pipe body 1. The detecting head 41 is located between the protective sheet 61 and the groove wall of the fixing groove 11, the protective sheet 61 is not connected to one side edge of the outer wall of the tube body 1, the protective sheet 61 and the outer wall of the tube body 1 are surrounded to form a humidity detecting port 101, the protective sheet 61 is not abutted to the detecting head 41, and the opening of the humidity detecting port 101 faces the air inlet end of the tracheal intubation. The protection piece 61 can protect the detection head 41, reduce the condition that the detection head 41 contacts with the inner wall of the trachea of the patient and influence humidity detection, and the detection head 41 can detect the gas entering from the outside of the humidity detection port 101 and detect the humidity condition in the trachea of the patient.

In addition, support fin 62 and protection piece 61 integrated into one piece, and support fin 62 is located the protection piece 61 towards the one side of body 1 outer wall, and support fin 62 keeps away from one side border fixed connection in the outer wall of body 1 of protection piece 61, supports fin 62 and is used for supporting protection piece 61, makes protection piece 61 be difficult for taking place the deformation because of receiving the extrusion of patient's endotracheal wall. The choked flow strip 63 and the outer wall integrated into one piece of body 1, choked flow strip 63 is that curved strip is protruding and its curved intrados face protection piece 61, and the tip fixed connection of choked flow strip 63 is in the border of protection piece 61, and choked flow strip 63 has seted up drainage groove 631 towards the one side of trachea cannula income gas end. Thus, when the mucus in the trachea of the patient adheres to the outer wall of the tube body 1 and flows towards the humidity detection port 101, the flow blocking strip 63 can block the mucus from continuously flowing towards the humidity detection port 101, and the drainage groove 631 guides the mucus to flow towards the wall surface of other parts of the tube body 1, so that the mucus is not easy to enter the humidity detection port 101 to cause the condition of inaccurate humidity data.

Referring to fig. 2 and 3, stay spring 12 in the fixedly connected with in the body 1, stay spring 12 extends the setting along the axis direction of body 1 in, stay spring 12 is used for supporting the pipe wall of body 1 in, make the structural strength of body 1 more difficult emergence deformation, 121 has been seted up to the outline of stay spring 12 in, draw-in groove 121 is the bar structure and its axis direction along stay spring 12 extends, draw-in groove 121 is provided with two, transmission line 42 card is located in a draw-in groove 121, gas tube 31 card is located in another draw-in groove 121.

The implementation principle of the reinforced tracheal cannula in the embodiment of the application is as follows: medical staff inserts the body 1 in the trachea of a patient, introduces gas into the cuff 2 through the indicating balloon 3, and the cuff 2 is expanded to abut against the inner wall of the trachea of the patient to complete the fixing work of the trachea cannula. The probe 41 can measure the humidity of a small amount of gas entering the humidity detection port 101 and transmit the measured value to the display screen 5 through the transmission line 42, so that medical staff can directly know the humidity condition in the trachea of the patient and take measures in time, and the probability of curing the patient is improved. The protection sheet 61 and the flow blocking strip 63 can block mucus on the inner wall of the trachea of the patient, so that the mucus on the inner wall of the trachea of the patient is not easy to enter the humidity detection port 101 to influence the detection work of the detection head 41.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
