Problems solved by technology

[0004] In order to solve the problem that the existing tracheal cannula lacks air filtration and humidification during use and thus easily causes inflammation such as bronchitis in patients, the present invention provides a tracheal cannula for antibacterial filtration, which is installed on the cannula body The cannula extension tube, and then set the antibacterial filter mechanism with filter gauze at the end of the cannula extension tube, and use physiological saline to keep the gauze in a wet state all the time, so as to complete the humidification and filtration of air, preventing dust and bacteria from entering Intratracheal

Embodiment 1

[0033] Such as figure 1 and 2As shown, a tracheal sleeve for antibacterial filtration includes an arc-shaped sleeve body 1 and a fixing bracket 101 arranged on the upper end of the sleeve body 1, and the fixing bracket 101 is fixed to it by the fixing bands 102 provided on its two sides. It is fixed on the neck of the patient, and a cannula extension tube 2 connected to the cannula body 1 is arranged on the fixed bracket 101, and a bacteriostatic filter mechanism 4 is arranged at the end of the cannula extension tube 2. The filter mechanism 4 includes an end cap 401 that blocks the end of the sleeve extension pipe 2 and an annular connection portion 402 that is arranged on one side of the end cap 401 and is connected with the sleeve extension pipe 2. The middle part of the end cap 401 is a circular opening hole, and the circular through hole communicates with the sleeve extension tube 2, and the end of the sleeve extension tube 2 is closed with gauze 405, and the edge of the ...

Embodiment 2

[0037] Since the gauze plays a filtering role in use, after a period of use, bacteria will grow on its surface. In order to kill bacteria and prevent bacteria from entering the trachea, this embodiment is improved on the basis of embodiment 1. Its main structure is the same as Embodiment 1 is the same, the difference is: as Figure 3-7 As shown, the sleeve extension tube 2 is provided with a gauze disinfection mechanism 3, and the gauze disinfection mechanism 3 includes a fixing ring 302 arranged around the inner wall of the sleeve extension tube 2 and a flip for cutting or opening the sleeve extension tube 2. Plate 301, the flap 301 is rotated and installed in the inner ring of the fixed ring 302 through the rotating rod 304 and the rotating pin shaft 303 on both sides respectively, and the gap between the outer side of the flap 301 and the inner wall of the fixed ring 302 is covered by a silicone seal ring 307 sealing; the rotating pin shaft 303 and the rotating rod 304 are ...

Embodiment 3

[0045] This embodiment is an improvement made on the basis of embodiment 2, and its main structure is the same as that of embodiment 2, the difference is that: Figure 4 and 7 As shown, one end of the liquid inlet elastic hose 305 is fixed in the buffer chamber 3011, and the other end is passed through the rotating pin shaft 303, and protrudes from the end of the rotating pin shaft 303, so that it can be fed to the buffer chamber by the liquid pressurization device. Inject disinfectant into it.

[0046] The liquid pressurizing device in this embodiment is an air bag, or other existing equipment, such as filling the air bag with disinfectant, and quickly squeezing the air bag, so that the disinfectant in the air bag can be ejected quickly, and then sprayed on the gauze. The volume of cavity 3011 is relatively small, and only one airbag with a volume of at least 1 decimeter is needed to quickly inject the disinfectant onto the gauze 405, and the 1 decimeter airbag can also be s...

Abstract

A tracheal sleeve for antibacterial filtration, a sleeve extension tube connected to the sleeve body is provided on a fixed bracket, and an antibacterial filtration mechanism is arranged at the end of the sleeve extension pipe, the antibacterial filtration mechanism includes The end cap for sealing the end of the casing extension pipe and the ring-shaped connection part arranged on one side of the end cap and connected with the casing extension pipe, the middle part of the end cap is a circular through hole, and the end of the casing extension pipe is sealed with gauze. The part is closed, and the edge of the gauze extends into the saline storage cavity provided in the annular connection part, and the saline in the saline storage cavity is injected through the saline injection tube on the side of the end cap. In the present invention, a bacteriostatic filter mechanism with gauze as the main body is arranged at the end of the casing extension tube, and the edge of the gauze is in the saline storage chamber, and the water absorption of the gauze is used to automatically draw the physiological saline in the saline storage chamber to keep it Humid state, so as to humidify and filter the air, and prevent the dust in the air from directly entering the trachea.

Description

technical field [0001] The present invention is designed to a tracheal tube in the field of medical instruments, specifically a tracheal tube for antibacterial filtration. Background technique [0002] In the prior art, patients with laryngeal cancer often need to undergo total or hemi-laryngectomy. After the operation, the larynx has been resected and cannot breathe through the larynx. Therefore, it is necessary to use a tracheal tube to communicate with the patient's trachea to construct a breathing passage. The existing tracheal cannula generally has an arc bent tube inserted into the trachea to communicate with the trachea, and the other end of the arc bent tube has a fixing frame for fixing it on the patient's neck. [0003] Because the patient breathes through the tracheal tube, the nasal cavity does not moisten and filter the air, and the dry air with bacteria and dust will directly enter the trachea, causing diseases such as bronchitis. Contents of the invention ...
