Description

Technical Field

[0001] The utility model relates to the field of healthcare equipment, in particular to a flat cervical traction device. Background Art

[0002] Cervical spondylosis is a sub-healthy disease that is becoming increasingly common in modern society. In particular, the number of cases of cervical spondylosis caused by maintaining poor postures for a long time, such as sitting in front of a computer or using a mobile phone for a long time, is increasing. Cervical spondylosis is mainly manifested as pain in the neck and shoulders, and even numbness in the arms or fingers caused by nerve compression. Cervical spondylosis mainly includes types such as soft tissue injury and cervical disc herniation. Among them, soft tissue injury is more common and requires appropriate physical therapy to relieve symptoms.

[0003] One of the existing treatment methods is drug treatment. Although it can relieve pain temporarily, it cannot fundamentally solve the problems of neck muscle tension and cervical spine burden, and long-term use of drugs may have side effects.

[0004] Another existing treatment method is to use medical-grade cervical traction devices or neck collars. These devices are usually large in size and often need to be used in specific treatment environments, such as hospitals or physical therapy centers. Therefore, the use of these devices is usually not convenient for patients to self-manage, and patients need to frequently go to the hospital or treatment center.

[0005] There are simple neck collars or home traction devices on the market. The advantage is that they are convenient for patients to operate at home and achieve self-management; the disadvantage is that the treatment effect is usually limited, and they cannot provide medical-grade treatment effects, and may aggravate neck injuries and increase pain when used improperly.

[0006] Therefore, there is an urgent need for an effective flat cervical traction device that can be used at home to overcome the above defects. Summary of the Utility Model

[0030] In order to describe in detail the technical content and structural features of the present utility model, the following further description is made in conjunction with the implementation manners and with reference to the drawings.

[0031] Please refer to Figure 1 , the flat cervical traction device 100 of the present utility model generally needs to be used in conjunction with a bed, a sofa or a chaise longue. For example, the flat cervical traction device 100 of the present utility model is spliced on one side of the bed, and the part of the human body below the neck lies on the bed, and the part above the neck lies on the flat cervical traction device 100 of the present utility model. The head is supported by the pillow support member 2 of the traction device, and the pillow support member 2 is rotated to a certain angle to stretch the cervical vertebra, so as to achieve the treatment effect.

[0032] Please refer to Figures 2 to 4 , the flat cervical traction device 100 of the present utility model includes a main body 1 and a pillow support member 2. Specifically, the main body 1 includes a supporting member 11 located at the top and a support member 12 connected below the supporting member 11. The main body 1 has a top surface 111, specifically, the supporting member 11 has a top surface 111, and the supporting member 11 is horizontally arranged. A through hole 112 penetrating up and down is provided on the top surface 111 of the supporting member 11, and the through hole 112 penetrates through one side surface of the supporting member 11 to form an opening 113.

[0033] Please refer to Figures 2 to 6 , the pillow support member 2 includes a neck support portion 21 and a head support portion 22. Specifically, the neck support portion 21 is a cylindrical structure, but not limited thereto. The neck support portion 21 is located at the opening 113 and is pivotally connected to the main body 1. The head support portion 22 is located in the through hole 112, and the head support portion 22 is a flat plate structure. It can be understood that the outer contour of the head support portion 22 matches the outer contour of the through hole 112. The neck support portion 21 pivots relative to the main body 1 so that the head support portion 22 has a first position parallel to the top surface 111 and a second position intersecting and lower than the top surface 111. When the pillow support member 2 rotates from the first position to the second position and stays at the second position, the cervical vertebra of the human body can be tractioned. For example, the second position has multiple gears. For example, the difference between each gear is 8°. Of course, in other embodiments, the difference between each gear is 9° or 10°, so it is not limited thereto. It can be understood that the stretching strength of the cervical vertebra by each gear of the pillow support member 2 is different. Every time it rotates downward by one gear, the stretching strength of the cervical vertebra is stronger. Therefore, the patient can reasonably adjust his own stretching strength according to his own rehabilitation situation.

[0034] Please refer to Figure 2 , Figure 3 and Figure 7, an electric button 3 is provided on the surface of the main body 1, a reduction motor 4 is provided inside the main body 1, the pillow support member 2 has a pivot shaft 211, and the reduction motor 4 is connected to the pivot shaft 211 through a coupling (not shown in the figure); the electric button 3 is electrically connected to the reduction motor 4. The electrical connection between the electric button 3 and the reduction motor 4 is common knowledge in the art, so it will not be elaborated here. Pressing the electric button 3 can drive the reduction motor 4 to rotate, and then drive the pillow support member 2 to rotate. Preferably, in this embodiment, the pillow support member 2 has an automatic memory function and can record the user's preference settings, simplifying the daily adjustment steps. Preferably, the material of the main body 1 is aluminum alloy, which has the advantages of light weight and high strength. Of course, the material of the main body 1 can be alloy steel, so it is not limited thereto.

[0035] Please refer to Figure 5 and Figure 8 , in this embodiment, a manual adjustment method can be used to adjust the rotation angle between the pillow support member 2 and the main body 1. The side wall of the neck support portion 21 facing the main body 1 has a plurality of inwardly recessed gear slots 212. All the gear slots 212 are arranged at intervals along a concentric arc. It can be understood that the center of the concentric arc is the pivot center of the pivot shaft 211. A clamping protrusion 5 protrudes in the direction of the side wall of the main body 1. An elastic member 6 is provided between the clamping protrusion 5 and the main body 1. The elastic member 6 always makes the clamping protrusion 5 have a tendency to extend into the gear slot 212 to engage with the gear slot 212. For example, the elastic member 6 is a spring, but it is not limited thereto. The clamping protrusion 5 has an L-shaped structure. One end is used to extend into the gear slot 212, and the other end is an operating end 51, which extends out of the surface of the main body 1 for the convenience of user operation. The surface of the main body 1 is provided with a hollow hole 114 for the operating end 51 to extend out, and the operating end 51 moves within the range of the hollow hole 114. When the angle of the pillow support member 2 needs to be adjusted, the user pushes the operating end 51 by hand to separate the clamping protrusion 5 from the gear slot 212. At this time, the pillow support member 2 can rotate relative to the main body 1. When it rotates to the next angle, the user releases the operating end 51, and the clamping protrusion 5 resets under the action of the elastic member 6 to engage with the gear slot 212 to lock the pillow support member 2 and the main body 1.

[0036] Please refer to Figure 6, the neck support part 21 includes a pivot shaft 211 and a soft elastic layer 23 sleeved outside the pivot shaft 211. Specifically, the pivot shaft 211 is located at the center line of its cylindrical structure. Preferably, in this embodiment, the soft elastic layer 23 is memory foam. Specifically, the headrest part 22 includes a substrate layer 221 and a soft elastic layer 23 covering the outside of the substrate layer 221. Preferably, in this embodiment, the soft elastic layer 23 is memory foam. By virtue of the outer layers of both the neck support part 21 and the headrest part 22 being memory foam, the memory foam material can effectively disperse pressure and increase comfort. More specifically, the headrest part 22 further includes a non-slip cloth cover (not shown), the non-slip cloth covers the outside of the soft elastic layer 23, and a number of silicone printing dots are provided on the non-slip cloth cover, so as to achieve the anti-slip effect. Specifically, in this embodiment, the neck support part 21 and the headrest part 22 are of an integrally formed structure; of course, in other embodiments, the neck support part 21 and the headrest part 22 are of a split structure. When the neck support part 21 and the headrest part 22 are of a split structure, both ends of the neck support part 21 are rotatably connected to the main body 1, the neck support part 21 can rotate freely relative to the main body 1, and no driving power source is required. The headrest part 22 includes a fixed pivot end and a free end, and the driving power source is built into the main body 1 and pivotally connected to the fixed pivot end. It can be understood that the driving power source is a reduction motor 4.

[0037] Please refer to Figure 2 , Figure 3 , Figure 9 and Figure 10 , there are multiple support members 12 and they are arranged at intervals around the circumferential direction of the supporting part. For example, the support member 12 is a support rod, but not limited thereto. Specifically, in this embodiment, the support member 12 includes an upper support member 121, a lower support member 122 and a sleeve 123 installed between the upper support member 121 and the lower support member 122. The top end of the upper support member 121 is installed on the bottom surface of the supporting member 11, the bottom end of the upper support member 121 is connected to the top of the sleeve 123 and can rotate relative to the sleeve 123; an internal thread 1231 is provided on the inner wall of the sleeve 123, an external thread 1221 is provided outside the lower support member 122, and the top end of the lower support member 122 is threadedly connected to the sleeve 123; by rotating the sleeve 123, the lower support member 122 can move up and down relative to the sleeve 123 to adjust the height of the support member 12, which is convenient to adjust the height of the flat cervical traction device 100 according to the needs of the user and convenient for the pillow support 2 to adapt to beds or sofas of any height. More specifically, a bearing 124 is provided between the bottom end of the upper support member 121 and the top end of the sleeve 123. The inner ring of the bearing 124 is connected to the bottom end of the upper support member 121, and the outer ring of the bearing 124 is fixedly connected to the sleeve 123, so as to meet the requirement that when the sleeve 123 rotates, the upper support member 121 remains stationary. Preferably, an anti-slip pad is further provided at the bottom of the lower support member 122, and the anti-slip pad can increase the friction force to play an anti-slip role.

[0038] Please refer to Figure 11, in other embodiments, other height adjustment methods can also be adopted. For example, the upper support member 121 is sleeved outside the lower support member 122. The lower support member 122 has positioning holes 1222 spaced apart from each other in the height direction. The upper support member 121 is provided with a spring latch 125 that selectively engages and locks with the positioning holes 1222. The spring latch 125 always has a tendency to extend into the positioning holes 1222 so that the upper support member 121 and the lower support member 122 are relatively locked. When the spring latch 125 is pulled open, the upper support member 121 and the lower support member 122 are unlocked, so that the upper support member 121 can slide up and down relative to the lower support member 122. This adjustment method is well known to those skilled in the art, so it will not be elaborated here.

[0039] Combined with the accompanying drawings, the working principle of the flat cervical traction device 100 of the present invention will be described: Before use, the flat cervical traction device 100 of the present invention is assembled on one side of the bed / chaise longue. Rotate the sleeve 123 so that the height of the support member 12 changes to adjust the height, so that the neck support portion 21 is at an appropriate height. Operate the electric button 3 to rotate the pillow support member 2 to the angle required by the user. After adjustment, the user lies on the bed, the neck leans on the neck support member, and the head leans on the head support portion 22. By relying on the backward tilt of the head to stretch the cervical vertebra, and by relying on the head support portion 22 to support the head, it is possible to avoid straining the neck during traction.

[0040] Compared with the prior art, the flat cervical traction device 100 of the present invention is assembled and used on one side of the bed or chaise longue. It has a small shape and occupies a small volume, and is very suitable for home use. In addition, by means of the pillow support member 2 including the neck support portion 21 and the head support portion 22, when the user uses it, the body lies flat on the bed, the neck leans on the neck support portion 21, and the head leans on the head support portion 22. Before lying down or when lying down, adjust the head support portion 22 to the second position. At this time, the head of the human body is in a slightly backward tilted state. By relying on the backward tilt force of the head to achieve the effect of stretching the cervical vertebra, and by relying on the head support portion 22 to support the head, it is not possible to let the head hang completely under the action of gravity, avoiding secondary damage to the cervical vertebra caused by cervical lordosis.

[0041] The above-disclosed are only the preferred examples of the present invention, and the scope of the rights of the present invention cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
