For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

In the related art, the angle of the backrest is adjusted to enable the patient to sit up from lying flat, and the patient's head is raised to increase venous return, thereby reducing edema. However, some patients' heads droop due to lack of support, causing unsafe conditions, and the head and neck support cannot be adjusted in height and angle, and cannot be adjusted accordingly according to the patient's head position when sitting or standing.

In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a rehabilitation assisting device. When the patient is sitting and the head and neck support is not in a suitable position and needs to be adjusted, the height and angle of the head and neck support can be adjusted by an electric push rod, and the armrests can also be adjusted in height and angle according to the patient's condition, so that the patient can sit more comfortably.

The present application is described below with reference to the accompanying drawings and specific embodiments:

In conjunction with Figures 1 to 5, an embodiment of the present application provides a rehabilitation assisting device, including a main body component 1; the main body component 1 includes: a base 11, on the top of which an armrest frame 13 is symmetrically arranged; a backrest 12 is arranged on the base 11; a pillow 14 is arranged on the backrest 12; an adjustment component 2 is arranged in the base 11, and the adjustment component 2 includes: a groove body 21 is opened on one side of the base 11 and passes through the bottom of the armrest frame 13; a gear 22 is arranged on the outside of the backrest 12; a limit rod 23 is arranged in the groove body 21 and meshes with the gear 22; a slide groove 24 is opened on one side of the groove body 21; a spring 25 is arranged in the slide groove 24; a slider 26 is arranged in the slide groove 24 and one end is fixedly connected to one end of the spring 25; a pillow adjustment structure 27 is arranged on the backrest 12.

Specifically, when in use, the limit rod 23 is pulled so that the latching teeth on the limit rod 23 are disengaged from the gear teeth 22, and at the same time, the limit rod 23 squeezes the slider 26, so that the slider 26 is retracted into the slide groove 24, and the slider 26 compresses the spring 25 in the slide groove 24; at this time, because the latching teeth on the limit rod 23 are disengaged from the gear teeth 22, the backrest 12 is no longer limited and fixed, and at this time, directly pushing one end of the backrest 12 can make the backrest 12 rotate in the groove body 21, thereby changing the backrest 12 and the base 1 1, and when the backrest 12 is adjusted to a desired angle, the limit rod 23 is released, and the spring 1 25 is reset to push the slider 1 26 out of the slide groove 1 24, and the top of the slider 1 26 pushes against the limit rod 23, so that the latching teeth on the limit rod 23 and the gear teeth 22 on the backrest 12 are re-engaged to achieve the purpose of fixing the backrest 12. The head and neck support structure can be adjusted in height and angle through the pillow adjustment structure 27, so that the patient can achieve a comfortable effect when sitting or lying.

In some embodiments, the pillow adjustment structure 27 includes: an electric push rod 271 is arranged in the backrest 12; a slide groove 272 is opened on the backrest 12; a mounting seat 273 is arranged on the top of the electric push rod 271; a groove body 274 is opened on the mounting seat 273 and the pillow 14 is rotatably installed in the groove body 274; an electric push rod 275 is arranged in the mounting seat 273; a slide groove 3 276 is opened on the pillow 14; a slider 277 is arranged on the slide groove 3 276 and one end of which is fixedly connected to one end of the electric push rod 275.

Specifically, when the height of the pillow 14 is adjusted, the electric push rod 1 271 can be started to make the mounting seat 273 slide up and down in the second slide groove 272, and the mounting seat 273 drives the pillow 14 to slide up and down to adjust the height of the pillow 14; when the angle of the pillow 14 needs to be adjusted, the electric push rod 275 is started, and the electric push rod 275 drives the slider 277 to move. Because one end of the pillow 14 is rotatably connected to the second groove body 274, when the position of the slider 277 changes, the pillow 14 is moved. The angle of the pillow 14 will change around the center of the rotation connection at one end. Since the slider 277 is a linear motion and the pillow 14 is a circular motion, the position of the slider 277 on the pillow 14 will change. Therefore, the slider 277 needs to be set in the slide groove 3 276. The slider 277 can not only slide in the slide groove 3 276, but also needs to be able to rotate slightly. Therefore, the top of the slider 277 is round, so as to achieve the purpose of using the electric push rod 275 to change the angle adjustment of the pillow 14.

In some embodiments, the adjustment component 2 also includes an armrest adjustment structure 28, and the armrest adjustment structure 28 includes: an armrest 281, which is respectively arranged at the top of each of the armrest frames 13; a groove body 282, which has multiple openings at the bottom of each of the armrests 281; and an electric push rod 3 283, which is arranged in multiples in each of the armrest frames 13 and the top is rotatably connected to each of the groove bodies 282.

Specifically, the armrest adjustment structure 28 is arranged on the armrest frame 13, and the height and angle of the armrest can be adjusted according to the patient's condition through the armrest adjustment structure 28, and the armrest frame 13 plays the role of a bed baffle when the patient lies flat. When the height of the armrest 281 needs to be adjusted, all the electric push rods 283 are started synchronously to make the armrest 281 rise and fall on the armrest frame 13 to achieve the adjustment of the height of the armrest 281. When the angle of the armrest 281 needs to be adjusted, because one end of the electric push rod 283 is rotatably connected to the groove body 3 282 on the armrest 281, as long as the height of the electric push rod 3 283 is not consistent, but the top ends of the multiple electric push rods 3 283 under each armrest 281 are kept in a straight line, the angle of the armrest 281 can be adjusted.

In some embodiments, each of the electric push rods 283 is installed obliquely in the armrest frame 13, so that after the armrest 281 is slowly raised, the patient's arms can be stretched forward, making the patient more comfortable.

In some embodiments, a leg support body 3 is provided on one side of the base 11, so that the patient can place his legs thereon more comfortably.

In some embodiments, an adjustment component 2 4 is provided on the leg bracket body 3, and the adjustment component 2 4 includes: an electric push rod 4 41 is provided in the base 11; a slide groove 42 is opened on one side of the electric push rod 4 41; a slider 3 43 is provided on the slide groove 42 and one end of which is fixedly connected to one end of the electric push rod 4 41.

Specifically, when the angle of the leg support body 3 needs to be adjusted according to the patient's condition, the electric push rod four 41 is started, and the electric push rod four 41 drives the slider three 43 to move. Because one end of the leg support body 3 is rotationally connected to one side of the base 11, when the position of the slider three 43 changes, the leg support body 3 will change its angle around the center of the rotation connection at one end. Because the slider three 43 is a linear motion and the leg support body 3 is a circular motion, the position of the slider three 43 on the leg support body 3 will change, so the slider three 43 needs to be set in the slide groove four 42. The slider three 43 can not only slide in the slide groove three 276, but also needs to be able to rotate slightly. Therefore, the top of the slider three 43 is round, thereby achieving the purpose of using the electric push rod four 41 to change the angle adjustment of the leg support body 3.

In some embodiments, a fixing assembly 5 is provided on the pillow 14, and the fixing assembly 5 includes: a limiting groove 51 is opened on the outside of the pillow 14; one end of an elastic strap 52 is arranged on the outside of the pillow 14; a buckle 53 is arranged on the other end of the elastic strap 52; a slide groove five 54 is opened on the buckle 53; a slider four 55 is arranged in the slide groove five 54; and a spring two 56 is arranged in the slide groove five 54.

Specifically, when the patient's head has no supporting force, the elastic band 52 can be used to bind the patient's lower jaw and forehead to fix the patient's head to avoid safety hazards. When in use, the elastic band 52 is tied to the patient's head, and then the slider four 55 on the buckle 53 at one end of the elastic band 52 is pressed to retract the slider four 55 into the slide groove five 54. At the same time, the spring two 56 is compressed, and then the buckle 53 is inserted into the limiting groove 51, and the slider four 55 is released. The spring two 56 resets and drives the slider four 55 to reset. At this time, the pointed end of the slider four 55 is located in the limiting groove 51, thereby achieving the purpose of fixing the band and thus fixing the patient's head. When disassembling, the buckle 53 can be pulled out by pressing the slider four 55.

In some embodiments, two sliders four 55 are symmetrically arranged in the slide groove five 54, and the spring two 56 is located in the middle of the two sliders four 55. The two sliders four 55 can better limit and fix the buckle 53.
