Anti-drag tracheal catheter

Abstract

The utility model provides an anti-drag tracheal catheter which comprises a catheter body and a corrugated pipe, a plurality of notches are formed in one side of the catheter body in the length direction of the catheter body, a plurality of narrow slits are formed in the other side, opposite to the notches, of the catheter body, and rotating parts are formed between the notches and the corresponding narrow slits at intervals. The two sides of the narrow slits abut against each other, the two sides of the notches are open, and the two sides of the notches abut against each other and the two sides of the narrow slits are open by rotating the guide pipe body towards one sides of the notches; the corrugated pipe is arranged on the inner side of the guide pipe body. When the extending-in end of the catheter body abuts against the mucosa and suffers from forward resistance, all the rotating parts close to the extending-in end of the catheter body are stressed to be bent towards one side of the notch, the rotating parts are bent by virtue of force to offset the resistance, and the whole catheter body is bent into the shape of the advancing path of the catheter body, so that the advancing resistance of the catheter body is reduced, and the service life of the catheter body is prolonged. Smooth indwelling of the catheter body is ensured, and the corrugated pipe can ensure that gas does not leak from the notch and the narrow slit during ventilation.

Description

Technical Field

[0001] The utility model relates to the technical field of tracheal tubes, in particular to a drag-reducing tracheal tube. Background Art

[0002] The endotracheal tube is usually inserted into the trachea through the patient's oral cavity or nasal cavity through the throat. The endotracheal tube is an important means to ensure the patient's airway is unobstructed and effective ventilation. Affected by the position and structure of the human airway, the end of the traditional endotracheal tube will be constantly bent during the intubation process to finally reach the trachea. This process often damages the patient's airway mucosa or nasal mucosa, causing mucosal edema, bleeding, and even glottic cartilage damage, causing accidental injuries or other complications to the patient. At present, most endotracheal tubes use a curved structure to minimize the resistance during intubation, in order to reduce damage to the patient's mucosa, but the effect is still not ideal. In view of this, it is urgent to propose a endotracheal tube to reduce the resistance during intubation. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a drag-reducing tracheal tube to reduce the resistance during tube placement.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] The utility model provides a drag-reducing tracheal tube, comprising:

[0006] A catheter body, one side of which has a plurality of notches arranged along its length direction, and the catheter body has a plurality of narrow slits on the other side of each notch, and a rotating portion is formed between each notch and its corresponding narrow slit. In an initial state, the two sides of each narrow slit abut against each other and the two sides of the notch are open, and rotating the catheter body toward one side of the notch will make the two sides of each notch abut against each other and the two sides of the narrow slit open; and

[0007] The corrugated tube is arranged on the inner side of the conduit body and blocks each of the notches and slits.

[0008] Furthermore, one end of the catheter body is provided with an arc end head, and a through opening is opened on the arc end head.

[0009] Furthermore, a guide block is arranged on the outer side of the other end of the catheter body, and the guide block is arranged on the same side as the notch.

[0010] Furthermore, a liquid bag is arranged around the outer side of the catheter body near the arc end, and the liquid bag is connected to a liquid injection tube, and the liquid injection tube extends to the outer side of the other end of the catheter body.

[0011] Furthermore, a plurality of support rings are evenly distributed linearly on the bellows.

[0012] It can be seen from the above technical solution that the utility model provides a drag-reducing tracheal tube:

[0013] When the insertion end of the catheter body hits the mucosa and encounters resistance to the forward movement, the various rotating parts close to the insertion end of the catheter body will be forced to bend toward one side of the notch until the two sides of the notch abut against each other. The rotating parts are bent by leveraging the force to offset the resistance, and the catheter body as a whole is bent into the shape of its travel path, which is beneficial to reducing the travel resistance of the catheter body and ensuring smooth catheterization of the catheter body. The bellows can ensure that gas does not leak from the notch and narrow gap during ventilation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] like Figure 1-3 As shown, the drag-reducing tracheal catheter provided in this embodiment includes a catheter body 1 and a bellows 2.

[0025] See also Figure 1 and Figure 2 A plurality of notches 11 are arranged along the length direction of the catheter body 1 on one side thereof, and a plurality of narrow slits 12 are provided on the other side of the catheter body 1 relative to each notch 11. A rotating part 13 is formed between each notch 11 and its corresponding narrow slit 12, and the rotating part 13 connects the catheter body 1 into a continuous whole. In the initial state, the two sides of each narrow slit 12 abut against each other and the two sides of the notch 11 are open. Rotating the catheter body 1 toward the notch 11 side will make the two sides of each notch 11 abut against each other and the two sides of the narrow slit 12 open.

[0026] During specific use, the catheter body 1 is used for catheterization, and the side of the catheter body 1 where the notches 11 are located is directed toward the lower part of the patient's body to conform to the direction in which the catheter body 1 is about to be bent when the catheter is placed. When the insertion end of the catheter body 1 hits the mucosa and is subject to forward resistance, the rotating parts 13 close to the insertion end of the catheter body 1 will be forced to bend toward the notch 11 until the two sides of the notch 11 are against each other. The rotating parts 13 are bent by leveraging force to offset the resistance, and the catheter body 1 is bent as a whole into the shape of its travel path, which is beneficial to reducing the travel resistance of the catheter body 1 and ensuring smooth catheterization of the catheter body 1.

[0027] Of course, the shape of the catheter body 1 in the initial state can preferably be an arc (not shown) to further make the catheter body 1 conform to the human airway structure. However, it should be noted that in the initial state of the catheter body 1 of this shape, the two sides of each narrow slit 12 are still against each other and the two sides of the notch 11 are still open.

[0028] In order to make the insertion end of the catheter body 1 easier to turn and bend, preferably, one end of the catheter body 1 is provided with an arc end 14 , and a through opening 141 is opened on the arc end 14 .

[0029] Furthermore, a guide block 15 is provided on the outside of the other end of the catheter body 1, and the guide block 15 is provided on the same side as the notch 11. When the medical staff operates the catheter body 1 for catheter placement, they can check the position of the guide block 15 from the outside to determine the direction of the notch 11, thereby preventing the notch 11 from deflecting during the catheter placement process without the operator's knowledge.

[0030] In one embodiment, a liquid sac 16 is arranged around the outer side of the catheter body 1 near the arc end 14, and the liquid sac 16 is connected to an injection tube 17, which extends to the outside of the other end of the catheter body 1. By injecting physiological saline into the injection tube 17, the liquid sac 16 can be expanded to position the catheter body 1.

[0031] See also Figure 1-Figure 3 The bellows 2 is arranged on the inner side of the catheter body 1 and blocks each notch 11 and slit 12. The opening edges at both ends of the bellows 2 are respectively connected to the inner walls at both ends of the catheter body 1 to ensure that the gas does not leak from the notch 11 and slit 12 during ventilation.

[0032] like Figure 3 As shown, preferably, a plurality of support rings 21 are evenly distributed linearly on the bellows 2, and the support rings 21 are fitted and fixed to each fold of the bellows 2 to prevent the bellows 2 from collapsing due to negative pressure, thereby ensuring smooth transportation of gas.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
