Description

Technical Field

[0001] The utility model relates to the field of tracheal intubation fixators, in particular to a double-track tracheal intubation fixator. Background Art

[0002] Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction, etc., and is an important measure for rescuing patients with respiratory dysfunction. However, there are still some deficiencies in the existing tracheal intubation fixators. For example, the existing tracheal intubation fixators generally adopt a single-track structure, with uneven force and poor firmness. Secondly, the fixing structure inside the oral cavity is made of hard material, which will cause the patient's tongue to be compressed by hard objects, causing discomfort to the patient.

[0003] According to the publicly disclosed patent 202420145048.0, a double-track tracheal intubation fixator includes a main frame. There is a notch in the middle of the main frame. There are two sliding tracks arranged up and down on the outside of the main frame. A fixing group is arranged in the middle of the sliding tracks. There are two protective pads arranged up and down on the inside of the main frame. Fixing stickers are arranged on the left and right sides of the main frame. There are two fixing buckles arranged at the ends of the left and right ends of the main frame. The fixing buckles are connected with elastic straps. In the utility model, by opening the fixing buckles, aligning the notch of the main frame of this fixator with the patient's mouth, extending the fixing group into the patient's oral cavity, fixing the tracheal intubation in the fixing group, pasting the fixing stickers on the cheeks on both sides of the patient's oral cavity, then winding the elastic straps back from the back of the patient's head, and then using the fixing buckles to fasten. Through the double tracks, this fixator can work more firmly and reliably. Through the silica gel sleeve, the compression feeling can be reduced. In the process of implementing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although by setting two sliding tracks up and down, the fixing group is supported by two force points when moving, enhancing the stability of the tracheal intubation, and by adding a silica gel sleeve at the back end of the fixing sleeve, the compression on the patient's tongue can be reduced and the discomfort of the patient can be reduced. However, in the use process, for the traditional double-track tracheal intubation fixator, the fixing group is moved and adjusted through the sliding tracks. After the movement is completed, the limiting effect on the fixing group is not very good, and the fixing group has a displacement situation, resulting in the deviation of the position of the fixing group, affecting the stability of the use of the fixator. Therefore, new technical solutions need to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a double-track tracheal intubation fixator, so as to solve the technical problem that for the current traditional double-track tracheal intubation fixator, the fixing group is moved and adjusted through the sliding track. After the movement is completed, the limiting effect on the fixing group is not very good, and the fixing group has displacement, resulting in the deviation of the position of the fixing group and affecting the use stability of the fixator.

[0005] In order to achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a double-track tracheal intubation fixator, including a fixed housing, and further including:

[0006] Arc-shaped holes are opened at the front end of the fixed housing;

[0007] Double-track mechanisms are opened at the upper and lower ends of the arc-shaped holes. The double-track mechanisms include a plurality of track grooves, and the plurality of track grooves are respectively opened at the upper and lower ends of the arc-shaped holes;

[0008] A sliding shell is slidably connected inside the track groove. A moving plate is arranged inside the sliding shell. One end of the moving plate is fixed with a connecting rod. The end of the connecting rod far from the moving plate passes through the sliding shell and is fixed with a pulling block. A spring is penetrated outside the connecting rod.

[0009] Preferably, both ends of the spring are respectively in contact with the sliding shell and the moving plate.

[0010] Preferably, a fixed sleeve extends into the arc-shaped hole, and clamping grooves are opened at the upper and lower ends of the fixed sleeve.

[0011] Preferably, one end of a clamping block is clamped into the clamping groove. The other end of the clamping block passes through the track groove and extends into the sliding shell. One end of the clamping block located inside the sliding shell is fixed with a connecting rod.

[0012] Preferably, hinges are fixed on both sides of the rear end of the fixed housing, and one end of a connecting band is fixed to the rear end of the hinge.

[0013] Preferably, an elastic binding band is fixed to the end of the connecting band far from the hinge.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model combines the track groove, the sliding shell and the moving rod, and a spring can be arranged inside the sliding shell through the combination of the track groove, and the spring will drive the moving plate, the connecting rod and the pulling block to move, so that the pulling block can press against the surface of the track groove to limit the position of the sliding shell and the fixed sleeve, avoiding the situation that the limiting function cannot be performed after the position adjustment of the fixed sleeve and the sliding shell is completed. At the same time, when pulling the pulling block, the card block can be removed from the card groove on the surface of the fixed sleeve, and the fixed sleeve can be conveniently disassembled and assembled, so as to achieve double limiting. The traditional double-track endotracheal tube holder moves and adjusts the fixing group through the sliding track. After the movement is completed, the limiting effect of the fixing group is not very good. The fixing group is displaced, resulting in the position of the fixing group being offset, which affects the technical problem of the stability of the fixer.

[0016] 2. The utility model combines the track groove and the sliding shell, so that the track groove can be directly opened, and the sliding shell is set to slide in the track groove. The sliding mechanism is completely set inside the fixture, which reduces the overall volume of the fixture. After the track and the fixture are integrated, it is also unnecessary to set the sliding track on the surface of the fixture. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A dual-track endotracheal tube holder, see Figures 1 to 2, including a fixed housing 1, further comprising: an arc-shaped hole 201 opened at the front end of the fixed housing 1; a double-track mechanism opened at the upper and lower ends of the arc-shaped hole 201, the double-track mechanism including a plurality of track grooves 2 respectively opened at the upper and lower ends of the arc-shaped hole 201; a sliding housing 202 is slidably connected inside the track groove 2, a moving plate 207 is arranged inside the sliding housing 202, one end of the moving plate 207 is fixed with a connecting rod 205, the end of the connecting rod 205 away from the moving plate 207 passes through the sliding housing 202 and is fixed with a pulling block 203, a spring 206 is penetrated outside the connecting rod 205, the track groove 2 is directly opened, and the sliding housing 202 is arranged to slide in the track groove 2, and the whole sliding mechanism is arranged inside the fixator, reducing the overall volume of the fixator. After integrating the track with the fixator, there is no need to set a sliding track on the surface of the fixator. When it is necessary to adjust the positions of the fixing sleeve 204 and the sliding housing 202, the pulling block 203 can be pulled, so that the pulling block 203 drives the connecting rod 205 and the moving plate 207. Through the moving plate 207 squeezing the spring 206, the pulling block 203 can be moved. After the movement of the pulling block 203 is completed, the positions of the sliding housing 202 and the fixing sleeve 204 can be adjusted. After the adjustment is completed, the pulling block 203 is directly released. Through the elastic force of the spring 206, it will drive the moving plate 207, the connecting rod 205 and the pulling block 203 to move, so that the pulling block 203 abuts tightly against the surface of the fixed housing 1, thereby automatically limiting the fixing sleeve 204 and the sliding housing 202. In the traditional double-track tracheal intubation fixator, the fixing group is moved and adjusted through a sliding track. After the movement is completed, the limiting effect on the fixing group is not very good, and there is a displacement of the fixing group, resulting in an offset of the position of the fixing group, affecting the technical problem of the use stability of the fixator.

[0022] Specifically, refer to Figure 2 , both ends of the spring 206 are respectively attached to the sliding housing 202 and the moving plate 207.

[0023] Furthermore, refer to Figure 2 , a fixing sleeve 204 extends into the arc-shaped hole 201, and clamping grooves 209 are opened at the upper and lower ends of the fixing sleeve 204. When the pulling block 203 is pulled, since the connecting rod 205 is connected to the clamping block 208, the clamping block 208 can be moved out of the clamping groove 209 on the surface of the fixing sleeve 204, facilitating the disassembly and assembly of the fixing sleeve 204 and being able to cooperate with the pulling block 203 to achieve double limiting.

[0024] It should be noted that, refer to Figure 2 , one end of the clamping block 208 is clamped into the clamping groove 209, the other end of the clamping block 208 passes through the track groove 2 and extends into the sliding housing 202, and the end of the clamping block 208 located inside the sliding housing 202 is fixed with a connecting rod 205.

[0025] It should be noted that, refer to Figure 1, hinges 101 are fixed on both sides of the rear end of the fixed housing 1, and one end of a connecting band 102 is fixed to the rear end of the hinge 101.

[0026] It is worth introducing that, referring to Figure 1 , one end of the connecting band 102 away from the hinge 101 is fixed with an elastic band 103.

[0027] When using a double-track tracheal intubation fixator, when it is necessary to adjust the positions of the fixed sleeve 204 and the sliding housing 202, the pull block 203 can be pulled, so that the pull block 203 drives the connecting rod 205 and the moving plate 207. By squeezing the spring 206 through the moving plate 207, the pull block 203 can be moved. After the movement of the pull block 203 is completed, the positions of the sliding housing 202 and the fixed sleeve 204 can be adjusted. After the adjustment is completed, the pull block 203 is directly lowered. Due to the elastic force of the spring 206, it will drive the moving plate 207, the connecting rod 205 and the pull block 203 to move, so that the pull block 203 abuts against the surface of the fixed housing 1, thereby automatically limiting the fixed sleeve 204 and the sliding housing 202. When the pull block 203 is pulled, since the connecting rod 205 is connected to the clamping block 208, the clamping block 208 can be removed from the card slot 209 on the surface of the fixed sleeve 204, and the fixed sleeve 204 can be disassembled and assembled conveniently, and double limiting can be realized in cooperation with the pull block 203.
