Problems solved by technology

[0004] In order to solve the problem of granulation growth on the inner wall of the trachea when the existing metal tracheal cannula is used, the present invention provides a granulation growth inhibiting device for the metal tracheal cannula. The granulation growth inhibiting device inhibits granulation growth from two aspects, one On the one hand, the bottom end of the metal trachea cannula is covered with a silicone ring-shaped silicone substrate and a silicone sleeve, so that the silicone material is in contact with the trachea. Compared with metal materials, it can minimize friction and reduce the growth of granulation. On the one hand, by setting a liquid medicine chamber in the annular silica gel substrate, the liquid medicine chamber is connected through some holes inside the metal tracheal tube, thereby realizing the effect of regularly adding granulation growth inhibitors from the fixed bracket to it, and because the silica gel The material itself has a certain degree of hygroscopicity, which can slowly release the granulation growth inhibitor in the liquid cavity to the surface, thereby inhibiting the growth of granulation at the junction of the two

Embodiment 1

[0037] Such as figure 1 with 2 As shown, a device for inhibiting granulation growth for a metal tracheal cannula includes a drug solution slow-release mechanism 2 arranged at the bottom of the metal trachea cannula 1, and the drug solution slow-release mechanism 2 includes an annular silica gel fixed at the bottom of the metal trachea tube 1 The base plate 202, and the inner side of the annular silicone base plate 202 is flush with the inner wall of the metal tracheal sleeve 1, and the outer side exceeds the metal tracheal sleeve 1 to form a ring-shaped platform with the metal tracheal tube 1. On the ring-shaped platform A silicone sleeve 201 whose outer wall is flush with the outer side of the annular silicone substrate 202 is provided, and the bottom end of the metal trachea sleeve contacts the inner wall of the trachea through the silicone sleeve 201; , the liquid medicine chamber 203 communicates with the liquid medicine buffer chamber 105 provided inside the bottom end o...

Embodiment 2

[0044] This embodiment is an improvement made on the basis of Embodiment 1, and its main structure is the same as that of Embodiment 1, the difference is that: figure 2 with 3 As shown, the upper surface of the annular silica gel substrate 202 has an annular clamping platform 206, and the annular clamping platform 206 divides its upper surface into two parts, which are high on the inside and low on the outside, and the width of the inside is equal to the thickness of the metal trachea sleeve 1 , and fixed with the bottom of the metal trachea sleeve 1, the width of the outside is equal to the thickness of the silicone sleeve 201, and it is pasted together with the bottom of the silicone sleeve 201; the included angle of the ring card table 206 is provided with a ring The liquid-drawing channel 207 communicated with the liquid medicine chamber 203, and the bottom inner wall of the silicone sleeve 201 is in contact with the liquid medicine chamber 203 through the liquid-draw cha...

Embodiment 3

[0046] This embodiment is another improvement made on the basis of embodiment 1, and its main structure is the same as that of embodiment 1, the difference is that: figure 2 with 3 As shown, the upper surface of the annular silica gel substrate 202 has an annular clamping platform 206, and the annular clamping platform 206 divides its upper surface into two parts, which are high on the inside and low on the outside, and the width of the inside is equal to the thickness of the metal trachea sleeve 1 , and fixed with the bottom of the metal trachea sleeve 1, the width of the outside is equal to the thickness of the silicone sleeve 201, and it is pasted together with the bottom of the silicone sleeve 201; the included angle of the ring card table 206 is provided with a ring A liquid-absorbing channel 207 communicated with the liquid medicine chamber 203, a number of liquid-absorbing bands 204 are distributed on the bottom inner wall of the silicone sleeve 201, and these liquid-a...

Abstract

A device for inhibiting granulation growth for a metal trachea cannula, comprising a drug solution slow-release mechanism arranged at the bottom of the metal trachea cannula. The drug seepage hole is connected with the liquid medicine buffer chamber in the metal tracheal cannula, and the liquid medicine buffer chamber is connected with the drug dosing port through the liquid medicine adding hole, and the growth of granulation on the inner wall of the trachea is inhibited by regularly adding granulation inhibitors to the dosing port. In the present invention, a liquid medicine chamber is arranged in the annular silica gel base plate, and the liquid medicine chamber is communicated with some holes inside the metal tracheal tube, thereby realizing the effect of regularly adding granulation growth inhibitors from the fixed bracket into it, and due to the silica gel The material itself has a certain degree of hygroscopicity, which can slowly release the granulation growth inhibitor in the liquid medicine cavity to the surface, thereby inhibiting the growth of granulation at the junction of the two.

Description

technical field [0001] The invention is designed to a tracheal tube in the field of medical equipment, specifically a device for inhibiting granulation growth for a metal tracheal tube. 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. There are generally two types of tracheal cannula according to the material classification, one is a traditional metal cannula, and the other is a disposable synthetic plastic cannula. These two cannulas have their own advantages and disadvant...
