Description

Technical Field

[0001] The invention relates to the technical field of neck injury fixation, and in particular to an adjustable support and fixation device for neck injury. Background Art

[0002] The main function of the adjustable neck injury support device for neck injuries is protection and fixation. The neck brace can limit the movement of the neck to help protect and repair the injured neck tissue. In addition, the neck brace can also reduce the burden on muscles and joints, help relieve pain and inflammation, and provide good support to prevent further damage to the neck muscles and joints in inappropriate positions.

[0003] After searching the existing fully disclosed literature, Chinese Patent Publication No. CN113662729A discloses a neck fixation device. This patented technology mainly addresses the comfort requirements of most known neck braces. The jaw support plate of the neck brace is provided with a flexible component or material attached to the user's jaw. Therefore, when the user is affected by external factors, the neck brace user may subconsciously turn his neck quickly, thereby aggravating the neck fixation device of the user and hindering the recovery of the user's neck. This patent mainly uses a controller to identify factors in the external environment that may cause the user to turn his neck, and then controls the self-limiting jaw support to prevent the user from subconsciously turning his neck and avoid unnecessary injuries. However, this fixation device still has the following defects:

[0004] When the fixing device is used to fix a person with a neck injury, the neck needs to be manually squeezed, fixed and adjusted. The squeezing force of the fixation is sometimes too great to cause secondary injury, and sometimes too small to cause a large space for neck movement and poor squeezing and locking effect. Moreover, if the entire neck angle of the person with a neck injury exceeds the specified adjustment angle or does not exceed the specified standard angle, it is difficult to accurately adjust synchronously according to the specific numerical value, and the adjustment accuracy is poor. Therefore, a neck injury support adjustable fixing device is needed. Summary of the Invention

[0035] In some embodiments, as shown in the attached Figure 8 As shown, the clamping precision adjustment mechanism includes a linkage locking frame plate 37 installed on one side of the angle linkage guide frame plate 1, and the internal rotation of the linkage locking frame plate 37 is connected to a two-way locking screw 38, and the outer wall of the two-way locking screw 38 is threadedly connected with a first threaded sleeve support block 39 and a second threaded sleeve support block 40 from right to left. One end of the two-way locking screw 38 extends to the outside of the linkage locking frame plate 37 and is coaxially connected to a reduction drive motor 41. One side of the first threaded sleeve support block 39 and the second threaded sleeve support block 40 are both welded with a linkage clamping frame 42, and the other side of the angle linkage guide frame plate 1 is sequentially connected from outside to inside. A controller 35 and a lithium battery 36 are installed. The controller 35 is fixedly connected to the lithium battery 36 and the angle linkage guide frame plate 1 respectively.

The two linkage clamping frames 42 are symmetrically arranged, and the linkage clamping frame 42 is fixedly connected to the sleeve shaft block 18.

[0036] The operating principle of the adjustable neck injury support fixing device of the present invention is as follows.

[0037] When expanded, the controller 35 and other electrical equipment are powered by the lithium battery 36, and the reduction drive motor 41 fixed on the linkage locking frame plate 37 is started, and the reduction drive motor 41 drives the bidirectional locking screw 38 to rotate forward inside the linkage locking frame plate 37, and the bidirectional locking screw 38 drives the first threaded sleeve support block 39 to move to the right along the inner wall of the linkage locking frame plate 37 under the action of the thread, and the second threaded sleeve support block 40 moves to the left along the inside of the linkage locking frame plate 37 under the action of the thread, and the first threaded sleeve support block 39 and the second threaded sleeve support block 40 respectively drive the two linkage clamps The holder 42 is relatively far away, and the linkage clamping frame 42 drives the sleeve shaft block 18 to move, and the sleeve shaft block 18 drives the support column 20 to move the neck shoulder locking sleeve 21, and the two neck shoulder locking sleeves 21 are expanded. The sleeve shaft block 18 drives the rotating hollow rod 12 to move, and the rotating hollow rod 12 drives the neck injury support sleeve 13 to move, thereby generating a larger gap between the two neck injury support sleeves 13 and a larger gap between the two neck shoulder locking sleeves 21, so that the neck of the injured person is located between the two neck injury support sleeves 13, and the shoulder and neck are located between the two neck shoulder locking sleeves 21.

[0038] During precise clamping adjustment, the initial extrusion value is set on the controller 35, and the controller 35 starts the reduction drive motor 41. The reduction drive motor 41 drives the bidirectional locking screw 38 to reverse inside the linkage locking frame plate 37, and the bidirectional locking screw 38 drives the first threaded sleeve support block 39 to move to the left along the inner wall of the linkage locking frame plate 37 under the action of the thread, and the second threaded sleeve support block 40 moves to the right along the inside of the linkage locking frame plate 37 under the action of the thread. The first threaded sleeve support block 39 and the second threaded sleeve support block 40 respectively drive the two linkage clamping frames 42 to move relatively close, and the linkage clamping frame 42 drives the sleeve shaft block 18 to move. The two sleeve shaft blocks 18 are relatively close, and the sleeve shaft block 18 drives the support column 20 to move the neck shoulder locking sleeve 21, and the two neck shoulder locking sleeves 21 are squeezed relatively. The neck and shoulder of the person with neck injury is pressed, and the sleeve shaft block 18 drives the rotating hollow rod 12 to move, and the rotating hollow rod 12 drives the neck injury support sleeve 13 to move. The two neck injury support sleeves 13 are relatively squeezed on the two sides of the neck of the person with neck injury, and the neck and shoulder locking sleeve 21 drives the neck squeezing sensor 43 to squeeze. The neck squeezing sensor 43 can sense the specific value of the neck squeezing. When the value sensed by the neck squeezing sensor 43 is the same as the distance set by the controller 35, the servo reduction motor 33 is stopped by the controller 35, and the medical staff needs to ask the patient with neck injury whether he feels too tight or too loose. If it is too loose, a specified pressure value is added to the controller 35. If it is too tight, the pressure is reduced, so that the neck can be accurately squeezed, adjusted and locked.

[0039] During vertical precise adjustment, a specified vertical extrusion force is set on the controller 35, and the controller 35 starts the servo reduction motor 33 fixed on the sliding frame plate 34. The servo reduction motor 33 drives the locking linkage screw 32 to rotate forward inside the sliding frame plate 34, and the locking linkage screw 32 drives the threaded linkage block 31 to move forward along the inside of the sliding frame plate 34 under the action of the thread, and the threaded linkage block 31 drives the driving gear plate 30 to move forward, and the driving gear plate 30 drives each linkage gear 29 to rotate on the outer wall of the guide support rod 28. Since the guide support rod 28 and the sliding frame plate 34 are fixedly connected to the neck shoulder locking sleeve 21, the linkage gear 29 drives the sleeve-connected tilting hinge rod 27 to rotate upward.

[0040] When the positive angle of the neck is precisely adjusted, the specific tilt adjustment angle is determined according to the location of the neck injury, and the precise angle can be set on the controller 35. When the precise angle is a positive angle, the controller 35 starts the reduction motor 3 to drive the linkage screw 2 to rotate forward inside the angle linkage guide frame 1, and the linkage screw 2 drives the threaded collar block 4 to move upward along the inner wall of the angle linkage guide frame 1 under the action of the thread, and the threaded collar block 4 drives the two guide pillars 5 to move upward synchronously. At the same time, the guide pillar 5 drives the sleeve slider 6 to move the linkage support rod 7 upward, and the linkage support rod 7 drives the sleeve tilt rod 8 to move the concave hinge block 9 upward, and the concave hinge block 9 drives the linkage tooth plate 10 to slide to the left inside the sleeve guide slider 19, and the sleeve guide slider 19 and the sleeve The shaft blocks 18 are fixedly connected, the linkage gear plate 10 drives the linkage gear ring 11 to rotate clockwise, the linkage gear ring 11 drives the neck injury support sleeve 13 to rotate clockwise, and the linkage gear ring 11 drives the two linkage rotating rods 14 to rotate the linkage turntable 15, and the linkage turntable 15 drives the angle rotation end of the angle sensor 16 to rotate, and the angle sensor 16 can sense the rotation angle of the linkage gear ring 11 and the rotation angle of the neck injury support sleeve 13 at the same time. When the angle sensed by the angle sensor 16 is the same as the angle set by the controller 35, the driving of the reduction motor 3 is stopped by the controller 35, and the support column 20 supports the support frame 17, and synchronously realizes precise adjustment of the neck injury support sleeve 13 on both sides;

[0041] When the neck negative angle is adjusted, the precise angle is a negative angle, and the controller 35 starts the reduction motor 3 to drive the linkage screw 2 to reverse inside the angle linkage guide frame 1, and the linkage screw 2 drives the threaded collar block 4 to move downward along the inner wall of the angle linkage guide frame 1 under the action of the thread, and the threaded collar block 4 drives the two guide pillars 5 to move downward synchronously, and the linkage support rod 7 drives the sleeve tilting rod 8 to move the concave hinge block 9 downward, and the concave hinge block 9 drives the linkage gear plate 10 to slide to the right inside the sleeve guide slider 19, and the linkage gear plate 10 drives the linkage gear ring 11 to rotate counterclockwise, and the linkage gear ring 11 drives the neck injury support sleeve 13 to rotate counterclockwise, and the linkage turntable 15 drives the angle rotation end of the angle sensor 16 to rotate. When the angle sensed by the angle sensor 16 is the same as the angle set by the controller 35, the drive of the reduction motor 3 is stopped through the controller 35.
