Description

Technical Field

[0001] The utility model relates to the field of rehabilitation exercise devices, in particular to a lower limb exercise device. Background Art

[0002] Clinically, patients who undergo upper and lower limb surgery often suffer from complications such as joint stiffness, muscle atrophy, and muscle weakness due to pain and dysfunction in the affected limb, which seriously affects the function of the affected limb. The elimination of the above complications needs to be achieved through functional rehabilitation exercises. The process of eliminating related complications is the process of functional recovery of the patient's affected limb. In lower limb functional rehabilitation exercises, knee flexion and lower limb lifting are the most important contents. Clinically, due to pain and lack of relevant professional knowledge, patients are often unable to complete relevant functional exercises independently. Therefore, a simple operating device with adjustable functional exercise amplitude and covering the main exercise content of the lower limbs is proposed. Utility Model Content

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Reference Figure 1-4 As shown, a lower limb exercise device includes: a base 1, the cross-section of the base 1 is in the shape of a U-shaped, a lifting assembly 2, four groups of lifting assemblies 2 are arranged in the base 1, arranged at equal intervals and each group of lifting assemblies 2 can be independently controlled and combined controlled, the lifting assembly 2 includes a multi-section electric lifting rod 21 and a support rod 22, the multi-section electric lifting rod 21 drives the support rod 22 to move up and down.

[0032] The sliding assembly 4 includes a sliding rail 41 and a slider 42 that slides with the sliding rail 41. The bottom of the sliding rail 41 includes a fixing clip 411. The sliding rail 41 is installed on the edge of the bed frame through the fixing clip 411 (it should be noted that many existing hospital bed frames use metal square steel as the frame edge, with a cross bar structure inside, which is separated from the mattress, and the mattress generally does not exceed the frame). It can be removed when not in use to avoid taking up space when not in use. The top of the slider 42 is connected to the base 1, and the base 1 slides on the bed frame through the sliding assembly 4.

[0033] Among them, eight first sliding grooves 11 are arranged symmetrically and at equal intervals on the inner side wall of the base 1, and a connecting rod assembly 3 is provided in each of the first sliding grooves 11. The connecting rod assembly 3 slides up and down in the first sliding grooves 11. The connecting rod assembly 3 includes a first connecting rod 31 and a second connecting rod 32. The second connecting rod 32 is sleeved in the first connecting rod 31, and the end of the second connecting rod 32 is connected to the support rod 22. The connecting rod assembly 3 can assist the support rod 22 to move up and down, thereby enhancing the stability of the structure.

[0034] A sliding portion is provided on the slider 42, and the sliding portion cooperates with the second slide groove on the slide rail 41. A roller 421 is also provided on the lower end surface of the slider 42, and the roller 421 rolls on the side of the slide rail 41. Since the slider 42 and the slide rail 41 cooperate to form a cantilever beam structure, the addition of the roller 421 can share part of the force in the second slide groove to the outside, which is beneficial for the slider 42 to slide on the slide rail 41.

[0035] The support rod 22 is covered with a silicone pad to improve the comfort of the lower limb support. The support rod 22 can also be set to a shape with high ends and low middle to facilitate the placement of the lower limbs.

[0036] The slider 42 is provided with an adjusting bolt, and the adjusting bolt is tightened to fix the slider 42 and the slide rail 41 to prevent sliding when performing up and down lifting exercises.

[0037] It includes a control component 5 (the control component 5 adopts the existing motor control technology, so it is not elaborated), the control component 5 is arranged on the side of the base 1, the control component 5 is electrically connected to the four multi-section electric lifting rods 21, the control component 5 can be powered by an external power supply, and can also be powered by a built-in power supply.

[0038] Usage: first install the slide rail 41 on the longitudinal beam on the side of the bed frame, then install the slider 42 at the bottom of the base 1 onto the slide rail 41, place the lower limbs on the support rod 22, turn on the control component 5, control the multi-section electric lifting rod 21 to move up and down, and assist the lower limbs in lifting and lowering exercises. When lying flat, the lower limbs are lifted up and the lower limbs will form a certain inclination. The height of each support rod 22 can be set from the control component 5, so that the multiple groups of lifting components 2 form a certain inclination in height, which can provide better support for the lower limbs; adjust the middle two groups of lifting components 2 to be lower than the outer lifting components 2, and then place the heels on the middle support rod 22 to form a better support to avoid the heels accidentally slipping out of the support rod 22 during exercise. The base 1 is moved forward and backward through the sliding component 4 to allow the lower limbs to perform flexion and extension exercises.

[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
