[0002] An endotracheal tube is a medical device inserted into a patient's trachea and / or bronchi to create a temporary artificial breathing channel, especially for patients unable to breathe spontaneously. Common tube tips have one or two cuffs, which, when inflated, secure the tube and seal the airway. Tubes may also be inserted without cuffs. The tube body is usually made of polymer materials; some tubes use laser-resistant materials or are multilayered to protect against laser radiation. It is inserted into the patient's trachea via the nose / mouth or percutaneously. One end connects to an anesthesia ventilator via a breathing circuit to maintain the patient's respiration. It is provided sterilely and is for single use only.

[0003] Existing endotracheal tubes are prone to compression, twisting, or dislodgement when used on patients in the prone position. Their fixation is not entirely the same as that for patients in the supine or lateral positions. Currently, the main method used is to reinforce the fixation of the endotracheal tube with double-fixation tape and ties. However, in clinical practice, due to the special posture of patients, the endotracheal tube is often compressed, twisted, or dislodged, affecting oxygen delivery and endangering life in severe cases. Therefore, we propose an anti-compression fixation device for endotracheal tubes in patients in the prone position to solve the above problems. Utility Model Content

Detailed implementation method:

[0022] 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.

[0023] Please see Figure 1-4This utility model provides an embodiment of a device for preventing pressure on the endotracheal tube of a patient in prone ventilation, comprising a fixing base 1 and an endotracheal tube 4. The fixing base 1 has a groove 2 inside, and a positioning ring 3 is fixedly connected to the rear end of the fixing base 1. The endotracheal tube 4 is slidably connected within the positioning ring 3. A linkage component 5 is provided on the outer side of the fixing base 1. The linkage component 5 includes a base 51, a first fixing groove 52, a first connecting rod 53, a first linkage ring 54, a second fixing groove 55, a second connecting rod 56, and a second linkage ring 57. The fixing base 1 has a base 51 inside, and the base 51... The device has a first fixing groove 52 inside, a first connecting rod 53 inside the first fixing groove 52, a first linkage ring 54 at the upper end of the first connecting rod 53, two sets of second fixing grooves 55 on the inner wall of the first linkage ring 54, a second connecting rod 56 inside the second fixing groove 55, and a second linkage ring 57 on the inner side of the two sets of second connecting rods 56. The edges of the positioning ring 3, the first linkage ring 54 and the second linkage ring 57 are rounded. The fixing seat 1 is engaged by the slot 2, and then the endotracheal tube 4 is passed through the positioning ring 3 and the second linkage ring 57 in sequence and placed on the patient.

[0024] This device, through the setting of linkage component 5, solves the problem that the endotracheal tube is often compressed, twisted or dislodged due to the special posture of patients in the prone position, which affects the delivery of oxygen and endangers life in severe cases.

[0025] Furthermore, a groove 6 is provided on the rear side of the fixed base 1, and a slider 7 is fixedly connected to the bottom of the base 51. The inner diameter of the groove 6 is adapted to the slider 7. Figure 4 As shown, this structure is used to pull the endotracheal tube 4 along the slide groove 6 via the slider 7 when the patient moves. At the same time, the other end of the endotracheal tube 4 is pulled out from the positioning ring 3, so that the endotracheal tube 4 moves stably along the path, avoiding pulling on the endotracheal tube 4 and causing the endotracheal tube 4 to be removed from the patient.

[0026] Furthermore, the first connecting rod 53 is rotatably connected to the base 51 within the first fixing groove 52. Two sets of second fixing grooves 55 are located at the center of the left and right sides of the first linkage ring 54. The left and right sides of the second linkage ring 57 are fixedly connected to two sets of second connecting rods 56. The second linkage ring 57 is rotatably connected to the first linkage ring 54 via the second connecting rods 56. The endotracheal tube 4 is inserted into the second linkage ring 57, and the endotracheal tube 4 is fixed to the second linkage ring 57 using tape. Figure 2As shown, this structure is used to swing the endotracheal tube 4 when the patient moves. The endotracheal tube 4 drives the second linkage ring 57 to rotate up and down in the second fixed groove 55 through the second connecting rod 56. At the same time, it drives the first linkage ring 54 to rotate left and right in the first fixed groove 52 through the first connecting rod 53, so that the endotracheal tube 4 is aligned with the patient's orientation, avoiding bending or folding of the endotracheal tube 4 and affecting oxygen delivery.

[0027] Furthermore, a touch switch 9 is fixedly installed on the inner front wall of the slide 6, and an alarm 10 is fixedly installed inside the mounting base 1. The touch switch 9 is electrically connected to the alarm 10. Figure 3 and Figure 4 As shown, this structure is used to prevent the endotracheal tube 4 from dislodging when the patient moves and pulls it too hard, causing the slider 7 to contact the touch switch 9. The alarm 10 receives the signal and sounds an alarm to remind the patient or medical staff to prevent the endotracheal tube 4 from dislodging.

[0028] Furthermore, two sets of ball bearings 8 are movably connected to the bottom of the slider 7, and the two sets of ball bearings 8 are symmetrically arranged with the base 51 as the center. Figure 4 As shown, this structure is used to reduce the friction between the slider 7 and the groove 6 by means of two sets of balls 8. It can drive the slider 7 to move when the patient moves slightly, so that the slider 7 can slide stably in the groove 6.

[0029] Furthermore, the rear half of the fixed base 1 is semi-circular, and the sliding groove 6 is opened along the semi-circular path of the fixed base 1. For example... Figure 3 As shown, this structure is used so that the rear half of the fixed seat 1 is semi-circular, allowing the slider 7 to descend naturally along the slide groove 6 without the patient moving, thereby driving the endotracheal tube 4 back to its original position.

[0030] Furthermore, an adjusting rod 11 is threadedly connected to the front end of the fixed base 1, and a rubber gasket 12 is fixedly connected to the rear end of the adjusting rod 11. For example... Figure 3 As shown, this structure is used to connect to the fixed seat 1 by means of the adjusting rod 11 threadedly. Rotating the adjusting rod 11 causes the rubber pad 12 to move towards the inner wall of the slot 2, so that the fixed seat 1 can be easily locked at the side or head of the patient's bed.

[0031] Working principle: When using, such as Figure 1 and Figure 3 As shown, the slot 2 at the fixing seat 1 is secured to the patient's bedside or headboard. Rotating the adjusting rod 11 moves the rubber pad 12 towards the inner wall of the slot 2, fixing the fixing seat 1 in place. Then, the endotracheal tube 4 is passed sequentially through the positioning ring 3 and the second linkage ring 57, and fixed to the second linkage ring 57. Finally, it is placed on the patient. Figure 2As shown, when the patient moves, the endotracheal tube 4 swings, causing the second linkage ring 57 to rotate up and down in the second fixed groove 55 via the second connecting rod 56. Simultaneously, it causes the first linkage ring 54 to rotate left and right in the first fixed groove 52 via the first connecting rod 53, ensuring the endotracheal tube 4 is aligned with the patient's orientation and preventing bending or folding of the endotracheal tube 4. Figure 3 and Figure 4 As shown, when the patient moves, the endotracheal tube 4 is pulled along the slide groove 6 via the slider 7 and the ball bearing 8. At the same time, the other end of the endotracheal tube 4 is pulled out from the positioning ring 3, so that the endotracheal tube 4 moves stably along the path, avoiding pulling on the endotracheal tube 4 and causing it to fall off the patient. If the pulling force on the endotracheal tube 4 is too great, it will exceed the range of motion of the slider 7, causing the slider 7 to contact the touch switch 9. The alarm 10 receives the signal and sounds an alarm to remind the patient or medical staff to prevent the endotracheal tube 4 from falling off. When the patient does not move, the slider 7 can descend naturally along the slide groove 6, driving the endotracheal tube 4 back to its original position. The above is the complete working principle of this utility model.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
