Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to a rehabilitation equipment for bedridden patients to exercise their own functions. Background Technology

[0002] Currently, many patients undergoing surgeries such as cardiac surgery or orthopedics are forced to remain in bed for extended periods due to the surgery or their condition. This lack of movement hinders recovery and can lead to muscle atrophy, weakened immune function, and deep vein thrombosis (DVT). Acute pulmonary embolism caused by DVT is fatal. Therefore, assisting these patients with appropriate limb movement is a crucial task for healthcare professionals, improving treatment efficiency and reducing limb disuse. While rehabilitation therapists provide limb function exercises, this is the most common clinical approach. However, insufficient nursing and rehabilitation staff limits the time and frequency of rehabilitation sessions, making it difficult to achieve the desired immediate recovery. Furthermore, bedridden patients often find it difficult to get out of bed for exercise, and most existing rehabilitation equipment is unsuitable for bedridden patients, significantly restricting its use.

[0003] The utility model patent with publication number CN 219376006 U discloses a rehabilitation device for bedridden patients to exercise their own functions. The device adopts a mobile support design so that the entire device can be moved to the bedside. By pulling the exercise rod, with the help of an electromagnetic damping counterweight device, rehabilitation exercises can be performed on the upper arm; and the leg rehabilitation exercises can be performed through an electric assist device, exercise rope and exercise ring. However, the rehabilitation device still has the following problems in use: (1) The electromagnetic damping counterweight device and the electric assist device in the rehabilitation device rely on electronic components, which is expensive on the one hand, and cannot achieve complete autonomous training on the other hand. Moreover, it is very inconvenient for family members of patients who do not know how to operate such devices; (2) The rehabilitation device can only exercise the upper limbs and lower limbs separately, and cannot train them simultaneously. For patients who need to exercise both the upper limbs and lower limbs, the exercise effect needs to be improved. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a rehabilitation device for bedridden patients to exercise their own functions. Through a leg training frame and an upper limb training component, it can realize interactive exercise of the legs and upper limbs.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example 1:

[0036] See attached document Figure 1-6 The invention described is a rehabilitation device for bedridden patients to exercise their own functions. It includes a movable front fixation bracket 1 and a rear fixation bracket 2. A top plate 3 is provided between the front fixation bracket 1 and the rear fixation bracket 2. Two sets of leg training frames 4 are slidably connected to the bottom of the top plate 3. Two force adjustment components 5 that match the leg training frames are provided at the bottom of the top plate 3. Each leg training frame 4 is also connected to an upper limb training component 6.

[0037] Specifically, both the front fixation bracket 1 and the rear fixation bracket 2 adopt an inverted U-shaped structure, and both the front fixation bracket 1 and the rear fixation bracket 2 are equipped with casters 101 at their bottom. The casters 101 have a self-locking mechanism to fix the position of the entire rehabilitation device. The inverted U-shaped structure design of the front fixation bracket 1 and the rear fixation bracket 2 allows the hospital bed to be sandwiched between them, with the top plate 3 located directly above the hospital bed. At this time, the leg training frame 4 and the upper limb training component 6 are located above the hospital bed, close to the patient, facilitating rehabilitation training for bedridden patients.

[0038] The leg training frame 4 includes a support rod 401, a foot pedal 402, a limiting post 403, an extension shaft 404, a first wedge block 405, and a second wedge block 406. The support rod 401 is slidably connected to the bottom surface of the top plate 3. Specifically, it can be connected by a slider and a slide rail, which can ensure that the support rod 401 can only move along the long axis of the top plate 3 and will not tilt. The bottom of the support rod 401 is fixedly connected to the foot pedal 402, which is used to place the patient's foot. A limiting post 403 is fixedly and vertically provided on the front side of the foot pedal 402. The front end of the limiting post 403 is provided with an extension shaft 404, the diameter of which is smaller than the diameter of the limiting post 403. The front end of the extension shaft 404 is fixedly connected to the first wedge block 405, and the second wedge block 406 is slidably sleeved on the extension shaft 404. Both the first wedge block 405 and the second wedge block 406 have an isosceles trapezoidal structure and are arranged opposite to each other. A first spring 407 is provided between the second wedge block 406 and the limiting post 403. In order to fix the patient's foot, the foot pedal 402 is also provided with an adjustable strap 4021, which can be two elastic bands connected by Velcro or buckles.

[0039] The force adjustment assembly 5 includes a first threaded rod 501 fixedly connected to the bottom of the top plate 3. An inner rod 502 is slidably inserted through the inside of the first threaded rod 501. A second threaded rod 503 with the same diameter as the first threaded rod 501 is provided at the bottom of the inner rod 502. A triangular adjusting block 504 is provided at the bottom of the second threaded rod 503. A second spring 505 is provided between the top of the second threaded rod 503 and the bottom of the first threaded rod 501, and the second spring 505 is sleeved on the inner rod 502. Multiple counterweights 506 are threadedly connected to the first threaded rod 501.

[0040] With the patient's foot fixed on the foot pedal 402, when pushing the foot pedal 402 forward, the inclined surface at the top of the first wedge block 405 first contacts the adjusting block 504. As the first wedge block 405 moves horizontally forward, it compresses the adjusting block 504, causing it to move upward. This, in turn, drives the second threaded rod 503 and the inner rod 502 vertically upward, compressing the second spring 505. Because the second spring 505 is compressed, it exerts a downward force on the adjusting block 504. Consequently, when pushing the foot pedal 402, the patient must overcome the weight of the adjusting block 504, the second threaded rod 503, and the inner rod 502, as well as the force of the second spring 505, thus achieving a training effect. After the first wedge block 405 has completely passed the adjusting block 504, under the action of the second spring 505, the adjusting block 504 returns to its initial position. At this point, the bottom surface of the adjusting block 504 contacts the inclined surface at the top of the second wedge block 406, as shown in the attached diagram. Figure 4 As shown. Continuing to push the foot pedal 402 forward, the adjusting block 504 is squeezed again until the highest point of the second wedge block 406 completely passes through the adjusting block 504, thus performing rehabilitation training on the patient's leg strength. Depending on the patient's rehabilitation progress, when increased training intensity is needed, the counterweight block 506 on the first threaded rod 501 is moved to the second threaded rod 503, increasing the weight of the second threaded rod 503, requiring the patient to exert more force to push the foot pedal 402 forward.

[0041] Furthermore, the upper limb training component 6 includes a pull rope 601 and a pull ring 602. One end of the pull rope 601 is connected to the support rod 401, and the other end is connected to the pull ring 602. The bottom of the top plate 3 is provided with a fixed pulley 301 for supporting and winding the pull rope 601. During the process of moving the foot pedal 402 to the front using leg strength, the pull ring 602 is pulled up. Then, the patient pulls the pull ring 602 downwards, thereby pulling the entire leg training frame 4 backwards. During this process, the second wedge block 406 is first subjected to downward pressure from the adjusting block 504. As the limiting post 403, the extension shaft 404, and the first wedge block 405 move backwards, the second wedge block 406 slides into contact with the extension shaft 404, causing the second wedge block 406 and the first wedge block 405 to fit together. The first spring 407 is stretched, as shown in the attached diagram. Figure 5 As shown; then continue pulling the leg training frame 4 backward, the second wedge block 406 presses upward against the adjusting block 504 until the second wedge block 406 has completely passed through the adjusting block 504. The adjusting block 504 then gradually returns to its initial state along with the top slope of the first wedge block 405, thus achieving the effect of rehabilitation training for the patient's upper limb strength. This achieves an interactive training effect where the leg training frame 4 performs rehabilitation training for the patient's legs when moving forward, and performs rehabilitation training for the patient's upper limbs when moving backward.

[0042] Example 2:

[0043] Based on Embodiment 1, in order to adjust the height of the pull ring 602 in the initial state according to the patient's height, the support rod 401 is also provided with a rope winding mechanism 7 for adjusting the length of the pull rope 601.

[0044] For details, see attached. Figure 6 As shown. The rope winding mechanism 7 includes a winding post 701 for winding the pull rope 601. The support rod 401 has a mounting groove 4011. The winding post 701 is rotatably mounted in the mounting groove 4011. A driven gear 702 is sleeved on the winding post 701. A rolling gear 703 meshes with one side of the driven gear 702. The rolling gear 703 passes through the support rod 401, so that the rolling gear 703 can be operated from outside the support rod 401.

[0045] A limiting unit for limiting the winding post 701 is also provided between the winding post 701 and the support rod 401. The limiting unit includes a limiting external gear 704 sleeved on the winding post 701, a limiting internal gear ring 705 slidably disposed in the vertical direction in the mounting groove 4011, a third spring 706 disposed between the top of the limiting internal gear ring 705 and the top of the mounting groove 4011, and an operating handle 707 disposed on the side of the limiting internal gear ring 705. The operating handle 707 passes through the support rod 401, and the support rod 401 has through holes that match the operating handle 707 and the rolling gear 703, and the through holes are all connected to the mounting groove 4011. Lift the operating handle 707 upwards to disengage the limiting internal gear ring 705 from the limiting external gear 704. Rotate the rolling gear 703 to rotate the winding post 701, thereby retracting or extending the pull rope 601. After adjusting the pull ring 602 to the appropriate height, release the operating handle 707. The third spring 706 will push the limiting internal gear ring 705 downwards until it meshes with the limiting external gear 704. Since the limiting internal gear ring 705 cannot rotate within the mounting groove 4011, the rotation of the winding post 701 can be limited.

[0046] Application examples:

[0047] Patients with neurological disorders leading to limb dysfunction, such as stroke hemiplegic patients, or those unable to stand or sit up in the early post-stroke period, can benefit from rehabilitation exercises while lying down. These exercises can promote nerve function recovery, improve blood circulation, prevent muscle atrophy and joint stiffness, and enhance cardiopulmonary function. The specific operating procedure for using the self-regulating rehabilitation device of this invention during bed rest includes the following steps:

[0048] Step 1: Move the entire rehabilitation equipment to the vicinity of the hospital bed and secure the hospital bed within the U-shaped structure of the front fixation bracket 1 and the rear fixation bracket 2.

[0049] Step 2: Lift the operating handle 707 upwards to disengage the limiting internal gear ring 705 from the limiting external gear 704, rotate the rolling gear 703 to rotate the winding column 701, thereby retracting or releasing the pull rope 601. After adjusting the adjusting ring 602 to a suitable height, release the operating handle 707 to limit the initial height of the ring 602.

[0050] Step 3: The patient lies on the hospital bed, holding the pull ring 602 in his hand, stepping on the foot pedal 402 with his feet, and securing it with the strap 4021;

[0051] Step 4: The patient pushes the foot pedal 402 forward with their foot, squeezing the adjusting block 504 upward, compressing the second spring 505. After the first wedge block 405 has completely passed through the adjusting block 504, the adjusting block 504 returns to its initial position under the action of the second spring 505. At this time, the bottom surface of the adjusting block 504 contacts the top inclined surface of the second wedge block 406. Continuing to push the foot pedal 402 forward, the adjusting block 504 is squeezed again until the highest point of the second wedge block 406 has completely passed through the adjusting block 504. This process provides rehabilitation training for the patient's leg strength. Depending on the patient's rehabilitation progress, when increased training intensity is needed, the counterweight 506 on the first threaded rod 501 is moved to the second threaded rod 503, increasing the weight of the second threaded rod 503, requiring the patient to exert more force to push the foot pedal 402 forward. During this process, the pull ring 602 is pulled up, and the patient's upper limb is raised.

[0052] Step 5: After the foot pedal 402 moves to the frontmost position, the patient pulls the pull ring 602 downwards with their hand, thereby pulling the entire leg training frame 4 backwards. During this process, the second wedge block 406 is first subjected to downward pressure from the adjusting block 504. As the limiting post 403, the extension shaft 404, and the first wedge block 405 move backwards, the second wedge block 406 slides into contact with the extension shaft 404, causing the second wedge block 406 and the first wedge block 405 to fit together, and the first spring 407 is stretched. Then, the leg training frame 4 continues to be pulled backwards, and the second wedge block 406 presses upwards against the adjusting block 504 until the second wedge block 406 has completely passed through the adjusting block 504. The adjusting block 504 then gradually returns to its initial state along with the top slope of the first wedge block 405, thereby achieving the effect of rehabilitation training for the patient's upper limb strength. This achieves an interactive exercise effect where the leg training frame 4 performs rehabilitation training on the patient's legs when it moves forward, and performs rehabilitation training on the patient's upper limbs when it moves backward.
