Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a tracheal intubation fixation device. Background Technology

[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth or nose and through the glottis into the trachea or bronchus. It provides optimal conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure for rescuing patients with respiratory dysfunction. During endotracheal intubation, a fixator is usually used to fix the endotracheal tube to prevent displacement or dislodgement from the trachea, thereby protecting the tube and the patient.

[0003] However, most endotracheal intubation fixators on the market either attach the endotracheal tube to the patient's face with tape or fix the endotracheal tube by rotating a positioning plug with a threaded connection. However, tape is not only time-consuming and laborious but also difficult to remove. When fixing the endotracheal tube by rotating the positioning plug, the threaded connection between the plug and the fixator means that the plug may loosen when the fixator shakes, causing the endotracheal tube to fall off, which poses a certain safety hazard. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tracheal intubation fixation device, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a endotracheal tube fixation device, including a fixing plate, and further comprising: a through groove on one end surface of the fixing plate, a guide groove on the inner side wall of the fixing plate, and a damper provided on the inner side of the guide groove; a first spring sleeved on the outer surface of the damper; a movable plate fixedly connected to the top of the damper, and a lower pressure seat connected to one side of the movable plate; a first arc-shaped seat provided at the middle of the bottom end of the movable plate; a guide rod provided on one side of the top of the movable plate, and a pull plate connected to the other end of the guide rod; and a second arc-shaped seat distributed below the first arc-shaped seat.

[0007] Furthermore, a sponge pad is provided on one end surface of the fixing plate, a fixing seat is provided on the side wall of the fixing plate, and a take-up roller is connected to the bottom of the fixing seat. An elastic band is sleeved on the outer surface of the take-up roller, and Velcro is provided on the other end surface of the elastic band.

[0008] Furthermore, a positioning hole is provided on the upper surface of the take-up roller, a positioning rod passes through the inner side of the fixed seat, and an auxiliary slide plate is sleeved on the outer side of one end of the positioning rod. A second spring is fixedly connected to the upper surface of the auxiliary slide plate.

[0009] Furthermore, the guide grooves are symmetrically distributed along the vertical center line of the fixed plate, and the guide grooves and the fixed plate form an integrated structure.

[0010] Furthermore, the bottom of the first arc-shaped seat is provided with an arc-shaped surface, and the first arc-shaped seat and the second arc-shaped seat are distributed in a flat shape.

[0011] Furthermore, the positioning rod is slidably connected to the fixed seat via the auxiliary sliding plate, and the positioning rod and the fixed seat are vertically distributed.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a damper, a first spring, a lower pressure seat and an arc-shaped seat, this utility model can facilitate the effective clamping and limiting of the trachea during subsequent use. At the same time, it can clamp the trachea according to its size, which is more flexible. Moreover, compared with the existing method of clamping and limiting the trachea by rotating the positioning bolt, it is not only more stable, but also can effectively prevent the trachea from loosening, and is safer.

[0014] 2. By setting up a positioning rod, an auxiliary sliding plate, and a second spring, this utility model can achieve the positioning of the take-up roller during subsequent use. This makes it easier for the take-up roller to rotate even when the elastic bands on both sides are in contact with each other, thus avoiding affecting the subsequent positioning of the entire fixing device. This makes it more practical. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-6 As shown, this utility model is a endotracheal tube fixation device, including a fixing plate 1, and further including: a through groove 2 opened on one end surface of the fixing plate 1, a guide groove 3 opened on the inner side wall of the fixing plate 1, and a damper 4 provided on the inner side of the guide groove 3, a first spring 5 sleeved on the outer surface of the damper 4, a movable plate 6 fixedly connected to the top end of the damper 4, and a lower pressure seat 7 connected to one side of the movable plate 6, a first arc-shaped seat 8 provided in the middle of the bottom end of the movable plate 6, a guide rod 9 provided on one side of the top end of the movable plate 6, and a pull plate 10 connected to the other end of the guide rod 9, and a second arc-shaped seat 11 distributed below the first arc-shaped seat 8;

[0026] During operation, the pull plate 10 is first pulled longitudinally. This causes the guide rods 9, symmetrically arranged on both sides of its bottom, to move longitudinally. The longitudinal movement of the guide rods 9 then pulls the lower pressure seat 7. As the lower pressure seat 7 moves longitudinally, it causes the first arc-shaped seat 8 and the second arc-shaped seat 11 to separate. Simultaneously, the longitudinal movement of the lower pressure seat 7 causes the movable plate 6 to move longitudinally as well. The longitudinal movement of the movable plate 6 then causes the damper 4 and the first spring 5 to deform. The deformation of these two components generates a counterforce, which facilitates the subsequent longitudinal reset of the first arc-shaped seat 8. When the lower pressure seat 7 moves to... Once the correct position is achieved, the trachea is passed through the inside of the through-groove 2, extending into the patient's mouth. Then, the longitudinal tension applied to the pull plate 10 is released. Subsequently, under the reverse force generated by the deformation of the damper 4 and the first spring 5, the longitudinal movement of the pressure seat 7 is achieved. The pressure seat 7 drives the first arc-shaped seat 8 to press down on the trachea. With the help of the second arc-shaped seat 11, the trachea can be effectively clamped and limited. Since both arc-shaped seats can be made of rubber, the rubber arc-shaped seats can not only increase the friction with the trachea, but also prevent the trachea from being crushed, making the overall practicality higher.

[0027] A sponge pad 12 is provided on one end surface of the fixing plate 1, a fixing seat 13 is provided on the side wall of the fixing plate 1, and a take-up roller 14 is connected to the bottom of the fixing seat 13. An elastic band 15 is sleeved on the outer surface of the take-up roller 14, and a Velcro 16 is provided on the other end surface of the elastic band 15. One end of the elastic band 15 is fixed to the outer wall of the take-up roller 14 and wrapped around the outside of the take-up roller 14.

[0028] During operation, the arc-shaped surface of the inner wall of the fixing plate 1 is placed against the patient's face. At this time, the sponge pad 12 will make contact with the patient's face in advance, so that the sponge pad 12 can be used to provide simple protection for the patient's face and also to absorb sweat. Then, the elastic band 15 is pulled to rotate the winding roller 14, and the rotation of the winding roller 14 is used to retract and extend the elastic band 15. When the elastic bands 15 on both sides are retracted or extended to the appropriate length, the pulling of the elastic bands 15 is stopped. Then, the Velcro 16 on the surface of the elastic bands 15 on both sides can be used to connect the two elastic bands 15, so that the entire fixation device can be fixed to the patient's face.

[0029] The upper surface of the take-up roller 14 is provided with a positioning hole 17, the inner side of the fixed seat 13 is provided with a positioning rod 18, and an auxiliary slide plate 19 is sleeved on the outer side of one end of the positioning rod 18. A second spring 20 is fixedly connected to the upper surface of the auxiliary slide plate 19, and the other end of the second spring 20 is fixedly connected to the top of the inner cavity of the fixed seat 13.

[0030] During operation, after the take-up roller 14 has been used, the longitudinal tension applied to the top of the positioning rod 18 is released. As the positioning rod 18 moves longitudinally, it will drive the auxiliary slide plate 19 to move accordingly. The longitudinal movement of the auxiliary slide plate 19 will cause the second spring 20 to deform. Combined with the reverse force generated by the deformation of the second spring 20, the auxiliary slide plate 19 can be longitudinally reset when the longitudinal tension applied to the positioning rod 18 disappears. At this time, the auxiliary slide plate 19 drives the positioning rod 18 to longitudinally reset, so that one end of the positioning rod 18 is inserted into the inside of the positioning hole 17, thereby realizing the positioning process of the take-up roller 14.

[0031] The guide grooves 3 are symmetrically distributed along the vertical center line of the fixing plate 1, and the guide grooves 3 and the fixing plate 1 form an integrated structure.

[0032] During operation, the guide groove 3 can guide the movement of the movable plate 6, thereby improving the stability of the movable plate 6 during longitudinal movement.

[0033] The bottom of the first arc-shaped seat 8 is provided with an arc-shaped surface, and the first arc-shaped seat 8 and the second arc-shaped seat 11 are distributed in a flat shape;

[0034] During operation, the first arc-shaped seat 8 moves longitudinally under the action of the lower pressure seat 7. Since the arc-shaped grooves are opened on one end surface of both the first arc-shaped seat 8 and the second arc-shaped seat 11, the clamping and limiting treatment of the air tube can be achieved by using the two arc-shaped grooves.

[0035] The positioning rod 18 is slidably connected to the fixed base 13 via the auxiliary sliding plate 19, and the positioning rod 18 and the fixed base 13 are vertically distributed.

[0036] During operation, the longitudinal movement of the positioning rod 18 will cause the auxiliary slide plate 19 to move longitudinally as well, thereby improving the stability of the positioning rod 18 during the longitudinal movement of the auxiliary slide plate 19.

[0037] Working principle: The arc-shaped surface of the inner wall of the fixing plate 1 is fitted to the patient's face. At this time, the sponge pad 12 will make contact with the patient's face in advance, thus providing simple protection for the patient's face and absorbing sweat. Then, the elastic band 15 is pulled, which rotates the winding roller 14. The rotation of the winding roller 14 then controls the opening and closing of the elastic band 15. When the elastic bands 15 on both sides are opened or closed to the appropriate length, pulling the elastic bands 15 is stopped. Then, the Velcro 16 on the surface of the elastic bands 15 on both sides can be used to connect the two elastic bands 15 together, thus allowing the patient to... The entire fixation device is fixed to the patient's face. After the take-up roller 14 is used, the longitudinal tension applied to the top of the positioning rod 18 is released. As the positioning rod 18 moves longitudinally, it drives the auxiliary slide plate 19 to move accordingly. The longitudinal movement of the auxiliary slide plate 19 causes the second spring 20 to deform. Combined with the reverse force generated by the deformation of the second spring 20, the auxiliary slide plate 19 can be longitudinally reset when the longitudinal tension applied to the positioning rod 18 disappears. At this time, the auxiliary slide plate 19 drives the positioning rod 18 to longitudinally reset, so that one end of the positioning rod 18 is inserted into the inside of the positioning hole 17, thereby achieving the fixation of the take-up roller 14. Position processing: After the entire fixation device is worn, pulling the pull plate 10 longitudinally causes the guide rods 9, which are symmetrically arranged on both sides of its bottom, to move longitudinally. This longitudinal movement of the guide rods 9 pulls the lower pressure seat 7. When the lower pressure seat 7 moves longitudinally, it causes the first arc-shaped seat 8 and the second arc-shaped seat 11 to separate. Simultaneously, the longitudinal movement of the lower pressure seat 7 causes the movable plate 6 to move longitudinally as well. The longitudinal movement of the movable plate 6 then causes the damper 4 and the first spring 5 to deform. The deformation of these two components generates a counterforce, which facilitates the subsequent longitudinal reset of the first arc-shaped seat 8. And when the lower pressure... After seat 7 moves to the appropriate position, the trachea is passed through the inside of the through groove 2 and extended into the patient's mouth. Then, the longitudinal tension applied to the pull plate 10 is released. Then, under the reverse force generated by the deformation of the damper 4 and the first spring 5, the longitudinal movement of the pressing seat 7 is realized, so that the pressing seat 7 drives the first arc-shaped seat 8 to press down on the trachea. With the help of the second arc-shaped seat 11, the trachea can be effectively clamped and limited. Since both arc-shaped seats can be made of rubber, the rubber arc-shaped seats can not only increase the friction with the trachea, but also prevent the trachea from being crushed, making the overall practicality higher.

[0038] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
