Description

Technical Field

[0001] This utility model relates to the field of endotracheal intubation technology, specifically to an improved endotracheal intubation device. Background Technology

[0002] Endotracheal intubation is a technique that involves inserting a specially designed endotracheal tube through the glottis into the trachea. This technique provides optimal conditions for airway patency, ventilation and oxygen supply, respiratory suction, and prevention of aspiration.

[0003] Currently used endotracheal tube length adjustment structures generally fix the adjustment position by squeezing and clamping. However, due to the limited clamping force during use, such limiting structures require manual pulling to adjust the length, making it difficult to control the tube length positioning. This can easily cause discomfort and damage to the airway when inserted into the patient's airway, and the operation is cumbersome. In view of this, we propose an improved endotracheal tube. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an improved endotracheal cannula, featuring a limiting groove and a positioning component. This design effectively controls the position of the endotracheal cannula body after length adjustment, improving stability, preventing deviation, and achieving precise positioning. The V-shaped inclined design on the side of the limiting groove facilitates automatic adjustment of the limiting strip when the fixed tube is pulled, achieving positioning adjustment. The use of an elastic ring enhances the fixation of the positioning component's position, ensuring the stability of the endotracheal cannula body. The cooperation between the positioning groove and the positioning strip prevents the endotracheal cannula body from deflecting, improves the fixation of the insertion angle, and enhances user comfort. The combination of the connecting piece and the metal spring strengthens the reset strength, maintains a good fit between the limiting strip and the limiting groove, and ensures the limiting effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an improved endotracheal tube, comprising an endotracheal tube body, a fixing tube movably mounted on the outside of the endotracheal tube body, a positioning component that engages with the top of the fixing tube body, and an elastic elastic ring installed between the fixing tube and the positioning component.

[0008] The top of the endotracheal tube body is provided with several arc-shaped limiting grooves, and the two sides of the several limiting grooves facing each other form a V shape.

[0009] The positioning component includes an elastic plate, a connecting piece is fixedly provided at the bottom of the elastic plate, and an arc-shaped limiting strip is fixedly provided at the lower end of the connecting piece, and the limiting strip is adapted to and connected to the limiting groove.

[0010] This invention, through the opening of a limiting groove and the cooperation of a positioning component, can limit the position of the endotracheal tube body and the fixed tube at their connection. This structural combination can improve the limiting of the position after the length of the endotracheal tube body is adjusted. At the same time, the V-shaped inclined setting on the side of the limiting groove can automatically squeeze the displacement of the internal limiting strip when the fixed tube is pulled to move, thereby achieving the effect of positioning adjustment. When fixed in use, the position of the positioning component can be limited by the action of the elastic ring. This structural combination can enhance the stability of the position of the endotracheal tube body after the length is adjusted, making it less prone to displacement, and at the same time achieve the effect of positioning adjustment, solving the problem of unstable control of the adjusted length.

[0011] Preferably, the top of the endotracheal tube body is provided with a positioning groove that communicates with several limiting grooves, and the top inner wall of the fixing tube is integrally formed with a positioning strip that is combined with the positioning groove.

[0016] (III) Beneficial Effects

[0017] This invention provides an improved endotracheal intubation method. It has the following beneficial effects:

[0018] (1) This improved endotracheal tube, through the opening of the limiting groove and the cooperation of the positioning component, can limit the position of the endotracheal tube body and the fixed tube. This structural cooperation can improve the limiting of the position after the length of the endotracheal tube body is adjusted. At the same time, the V-shaped inclined setting on the side of the limiting groove can automatically squeeze the displacement of the internal limiting strip when the fixed tube is pulled to move, thereby achieving the effect of positioning adjustment. When fixed in use, the position of the positioning component can be limited by the action of the elastic ring. This structural cooperation can enhance the stability of the position after the length of the endotracheal tube body is adjusted, and it is not easy to deviate. At the same time, it can achieve the effect of positioning adjustment, solving the problem of the difficulty in controlling the stability of the adjusted length.

[0019] (2) In this improved endotracheal tube, the position of the endotracheal tube body can be positioned by the cooperation of the positioning groove and the positioning strip, so that the deviation problem is not easy to occur during use. This can further improve the fixation of the insertion angle when inserted into the patient's airway, thereby further improving the comfort of use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5This utility model provides a technical solution: an improved endotracheal tube, including an endotracheal tube body 1, a fixing tube 2 movably mounted on the outside of the endotracheal tube body 1, a positioning member 3 that engages with the top of the fixing tube 2 and the endotracheal tube body 1, and an elastic ring 4 installed between the fixing tube 2 and the positioning member 3; the fixing tube 2 allows for easy adjustment of the length of the endotracheal tube body 1, the engagement of the positioning member 3 with the endotracheal tube body 1 limits the position of the fixing tube 2 and the endotracheal tube body 1, maintaining the stability of the adjusted position, and the elastic ring 4 strengthens the limitation of the position of the positioning member 3, maintaining the tightness of the fit between the positioning member 3 and the endotracheal tube body 1; the connecting groove 304 on the top of the positioning member 3 can connect with the inner wall of the elastic ring 4, further strengthening the tightness of the connection.

[0028] The top of the endotracheal tube body 1 is provided with several arc-shaped limiting grooves 101, and the two sides of the several limiting grooves 101 facing each other form a V shape. The positioning member 3 includes an elastic plate 301, and a connecting piece 302 is fixedly provided at the bottom of the elastic plate 301. An arc-shaped limiting strip 303 is fixedly provided at the lower end of the connecting piece 302, and the limiting strip 303 is adapted to be connected with the limiting groove 101. The inner side of the limiting groove 101 is V-shaped, which makes it easy for the limiting strip 303 to be squeezed and shifted upward, reducing the effect of moving resistance, and making it easy for the limiting strip 303 to drive the connecting piece 302 to move the side end of the elastic plate 301 upward.

[0029] In an embodiment of this utility model, the top of the endotracheal tube body 1 is provided with a positioning groove 102 that communicates with several limiting grooves 101, and the top inner wall of the fixing tube 2 is integrally formed with a positioning strip 204 that is combined with the positioning groove 102; the cooperation between the positioning groove 102 and the positioning strip 204 can keep the fixing tube 2 in the same position during movement, so that the endotracheal tube body 1 is not easy to deflect and the insertion end position is fixed.

[0030] In an embodiment of this utility model, the top of the fixing tube 2 is provided with a groove 201 that fits with the elastic plate 301, and the top side wall of the fixing tube 2 is provided with a through groove 202 that fits with the connecting piece 302. The groove 201 can hide the position of the elastic plate 301, so that the elastic plate 301 and the fixing tube 2 can achieve an integral connection. The through groove 202 facilitates the up and down movement of the connecting piece 302.

[0031] In the embodiment of this utility model, the fixing tube 2 is provided with a buckle groove 203 on both sides of the long side of the elastic plate 301, and the buckle groove 203 is long rectangular. The buckle groove 203 can be used to pinch the two sides of the elastic plate 301, so that the elastic plate 301 can be pulled upward, so that the limiting strip 303 is separated from the limiting groove 101, thus achieving the effect of quickly adjusting the position of the fixing tube 2.

[0032] In an embodiment of this utility model, an elastic groove 401 is provided through the outer edges of the elastic ring 4, and the groove cavity of the elastic groove 401 is honeycomb-shaped; the setting of the elastic groove 401 can enhance the elastic stretching effect of the elastic ring 4, and is also easy to restore and not easily deformed.

[0033] In an embodiment of this utility model, the elastic plate 301 is internally wrapped with an elastic metal spring sheet 305, and the elastic plate 301 is made of rubber. The metal spring sheet 305 can enhance the strength of the elastic plate 301 and reduce the occurrence of deformation, thus maintaining the overall integrity.

[0034] Working Principle: This embodiment provides an improved endotracheal tube. When adjusting the length of the endotracheal tube body 1 inserted into the airway, first pull one end of the endotracheal tube body 1, then hold both sides of the fixing tube 2 with the other hand, avoiding the position of the positioning piece 3. Next, pull the fixing tube 2 to move it. Under the squeezing force, the limiting strip 303 in the limiting groove 101 is squeezed outwards, thus separating from the limiting groove 101 and entering the adjacent limiting groove 101 during the movement. This process is repeated until it reaches the designated adjustment length, at which point it automatically engages. This structure achieves the function of limiting adjustment. The connection plates 302 at both ends of the elastic plate 301 enhance the limiting effect and increase the resistance to movement. At the same time, the movement of both ends allows the elastic plate 301 to move up and down horizontally, making it less prone to bending and maintaining the integrity of the elastic plate 301. This also strengthens the fit of the limiting strip 303 into the limiting groove 101. Meanwhile, the cooperation between the positioning groove 102 and the positioning strip 204 can prevent the fixing tube 2 from deflecting during movement, keeping the angle of the endotracheal tube body 1 fixed during insertion, making it less likely to touch the airway wall, and reducing discomfort caused by length adjustment. In this way, the convenience of length adjustment of the endotracheal tube body 1 can be improved with the cooperation of the overall structure.

[0035] This utility model comprises: 1. a endotracheal tube body; 101. a limiting groove; 102. a positioning groove; 2. a fixing tube; 201. a groove; 202. a through groove; 203. a buckle groove; 204. a positioning strip; 3. a positioning component; 301. an elastic plate; 302. a connecting piece; 303. a limiting strip; 304. a connecting groove; 305. a metal spring; 4. an elastic ring; 401. an elastic groove. All components are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that currently used endotracheal tube length adjustment structures generally fix the adjustment position by squeezing and clamping. However, such limiting structures have limited clamping force during use, requiring manual pulling to complete the length adjustment operation. The difficulty in controlling the length of the endotracheal tube during insertion can cause discomfort and damage to the airway, making the procedure cumbersome. Therefore, we propose an improved endotracheal tube. This invention combines the aforementioned components, incorporating a limiting groove and a positioning element to effectively control the position of the endotracheal tube after length adjustment, improving stability, preventing deviation, and achieving precise positioning. The V-shaped inclined design on the side of the limiting groove facilitates automatic adjustment of the limiting strip when the tube is pulled, achieving positioning adjustment. The use of an elastic ring enhances the fixation of the positioning element, ensuring the stability of the endotracheal tube's position. The cooperation between the positioning groove and the positioning strip prevents the endotracheal tube from deflecting, improves the stability of the insertion angle, and enhances user comfort. The combination of the connecting piece and the metal spring strengthens the reset strength, maintains a good fit between the limiting strip and the limiting groove, and ensures the limiting effect.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
