Description

Technical Field

[0001] This utility model belongs to the field of medical device technology research, specifically relating to a multifunctional portable lower limb assistive exercise and rehabilitation device. Background Technology

[0002] Hemiplegia, also known as paralysis of one side of the body, refers to complete paralysis of half of the body caused by central nervous system damage from various causes, resulting in paralysis of the upper or lower limbs. It is often accompanied by damage to the ipsilateral cranial nerves and is most commonly seen in intracranial lesions or stroke. Because hemiplegic patients need to be bedridden for extended periods, their lower limbs are often unable to move, leading to muscle atrophy and weakness. Therefore, assistive exercises are necessary to prevent muscle atrophy, promote functional recovery, help patients increase their confidence, and reduce the need for medical and family assistance to enable independent practice.

[0003] Patent CN208641203U discloses a lower limb function exercise belt for bedridden patients, comprising: a hard-soled shoe, a shoe cover, a reinforcing strap, an extended exercise belt, a connecting piece, and an adjustable buckle. The shoe cover is a rectangular piece of fabric, with its lower edge sewn to the top edge of the hard-soled shoe. A pair of reinforcing straps are symmetrically arranged on both sides of the hard-soled shoe, with both ends sewn to the shoe cover. The extended exercise belt is a strip-shaped rope, connected to the reinforcing strap via the connecting piece. The adjustable buckle is located on the extended exercise belt. When using the product, the patient places their foot on the top surface of the hard-soled shoe, ensuring that the entire foot is fully in contact with the top surface of the hard-soled shoe. Next, the patient adjusts the adjustable loops to adjust the length of the extension exercise strap according to their own height and exercise needs. Then, the patient holds both ends of the extension exercise strap with both hands to keep the extension exercise strap and the reinforcing strap taut. Finally, because the hard-soled shoe is under tension, the contact area between the patient's foot and the hard-soled shoe is increased, which can effectively position the foot and thus assist the patient in exercising lower limb function.

[0004] The enhanced exercise band in the above-mentioned technical solution enables patients to move their lower limbs horizontally. However, in rehabilitation exercises where the patient raises or lowers their lower limbs using the extended exercise band, the patient can only raise or lower their lower limbs using the extended exercise band located on both sides of the hard-soled shoe. Furthermore, the hard-soled shoe in the above-mentioned technical solution cannot fix the upper and lower ends of the patient's foot. Moreover, when the patient raises their lower limb from the sides, they need to pull the enhanced exercise band taut to increase the friction between the hard-soled shoe and the patient's foot, preventing the patient's foot from slipping off the hard-soled shoe. This is very inconvenient, especially for patients with less strength, as the enhanced exercise band in the above-mentioned technical solution cannot effectively raise the lower limb, resulting in poor performance.

[0005] In addition, the lower limb exercise belt provided by the above-mentioned technical solution has a single function and cannot correct problems such as foot drop and pressure sores that are prone to occur after hip joint surgery in a timely manner. Utility Model Content

[0006] The purpose of this invention is to overcome the limitations of existing lower limb exercise belts, which cannot lift or lower the patient's lower limbs, have poor effectiveness, and are limited in function, failing to promptly correct problems such as foot drop and pressure sores that easily occur in the lower limbs after hip joint surgery.

[0007] To achieve the above objectives, the technical approach adopted by this utility model is as follows: a horizontal exercise belt and a vertical exercise belt are provided on the side of the foot support pad, and a wrapping belt for fixing the patient's foot is provided on the side of the foot support pad that fixes the patient's foot; when in use, the patient can hold the horizontal exercise belt to move the lower limb left and right in the horizontal direction, or the patient can hold the vertical exercise belt to raise or lower the lower limb in the vertical direction, so as to realize the patient's movement exercise in multiple directions such as up, down, left, and right. The structure is simple and the rehabilitation training effect is good.

[0008] In addition, a stabilizing board is installed inside the foot support pad to elevate the patient's affected limb. During the patient's horizontal rehabilitation exercises, the stabilizing board can fix the position of the patient's foot and ankle, keeping the patient's foot parallel to the bed and preventing the patient's foot from turning inward or outward. This is beneficial to the patient's joint stability. In the non-rehabilitation training phase, the stabilizing board can slightly elevate the patient's affected limb to prevent pressure sores, foot drop, toes pointing downward, etc., while keeping the patient in an abducted and neutral functional position. This is especially suitable for elderly patients and other patients who do not cooperate with rehabilitation exercises.

[0009] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0010] A multifunctional portable lower limb assistive exercise rehabilitation device includes a foot support pad and two transverse exercise bands symmetrically arranged on both sides of the foot support pad. The foot support pad is equipped with:

[0011] The longitudinal exercise band is located at the top of the foot support pad;

[0012] The wrapping strap is placed on the side of the foot support pad that contacts the patient's foot;

[0013] The stabilizing plate includes a support portion and a fish tail portion connected to the support portion. The support portion is located within the receiving cavity of the foot support pad, and the fish tail portion is located outside the foot support pad.

[0014] Further specifying the above technical solution, preferably, the foot support pad also includes:

[0015] The storage strap is located on the side of the foot support pad away from the patient's foot.

[0016] Further limitations on the above technical solutions include:

[0017] The reinforcing plate is placed on the foot support pad and is arranged to cross the storage strap.

[0018] To further define the above technical solution, the reinforcing plate has a T-shaped structure.

[0019] Further specifying the above technical solution, the parcel strip includes:

[0020] Ankle fixation part, connected to the foot support pad;

[0021] Instep fixation part; two instep fixation parts; the end of each instep fixation part is connected to the foot support pad, and the side of the instep fixation part near the ankle fixation part is connected to the ankle fixation part. Beneficial effects

[0022] I. This utility model, through the combined design of a horizontal exercise belt and a vertical exercise belt, enables the lower limbs to move left and right in the horizontal direction, and to lift or lower the lower limbs in the vertical direction, thereby achieving multiple directions of movement exercise for the patient, such as up, down, left, and right. It has a simple structure and good rehabilitation training effect.

[0023] II. This utility model, through the combined design of a foot support plate and a stabilizing plate, provides support to the patient's feet during horizontal translational rehabilitation exercises. The fishtail portion of the stabilizing plate prevents foot rotation, i.e., prevents internal or external rotation of the ankle, thus maintaining joint stability in the affected limb, ensuring rehabilitation effectiveness, and promoting patient recovery. Furthermore, during non-rehabilitation exercise periods, the stabilizing plate can slightly lift the patient's feet so that they do not contact the bed surface, preventing pressure sores, foot drop, and downward pointing of the toes. Simultaneously, it allows the patient to maintain an abducted, neutral functional posture, making it particularly suitable for elderly patients and other patients who are uncooperative with rehabilitation exercises.

[0024] Third, this utility model, through the setting of the storage strap, can store the longitudinal exercise belt during the process of the patient using the transverse exercise belt to perform rehabilitation exercises on the lower limbs in the horizontal direction, preventing the longitudinal exercise belt from falling off and ensuring the normal progress of rehabilitation training; similarly, during the process of the patient using the longitudinal exercise belt to perform rehabilitation exercises on the lower limbs in the vertical direction, the storage strap can store the transverse exercise belt to prevent the transverse exercise belt from falling off and ensure the normal progress of rehabilitation training.

[0025] IV. This utility model, through the combined design of the storage strap and the reinforcing plate, can prevent the exercise belt from falling off between the storage strap and the foot support pad, and has a good storage effect.

[0026] V. The multifunctional portable lower limb assistive exercise rehabilitation device provided by this invention can be used by patients, especially the elderly, on the first day after hip fracture surgery, so that patients can maintain an abducted and neutral functional position and prevent foot drop, pressure sores and other conditions.

[0027] VI. The multifunctional portable lower limb assistive exercise rehabilitation device provided by this utility model has a simple structure, is easy to carry and use, and can be used for postoperative rehabilitation training as well as for daily rehabilitation exercises after patients are discharged from the hospital.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0040] This invention is applicable to postoperative rehabilitation exercises for hip joints, and is especially suitable for patients who are lying flat on a hospital bed to perform rehabilitation training.

[0041] Example 1

[0042] like Figure 1-5 As shown, this utility model provides a multifunctional portable lower limb assistive exercise rehabilitation device, including a foot support pad 5 and a longitudinal exercise belt 1, a wrapping belt 2, a storage bag 3, a transverse exercise belt 6, and a stabilizing plate 7 disposed on the foot support pad 5. The foot support pad 5 has a downward-facing receiving cavity, and the stabilizing plate 7 is located inside the receiving cavity, with its bottom located outside the receiving cavity.

[0043] The foot support pad 5 is made of rigid material, specifically plastic. In practical applications, the outer side of the foot support pad 5 is covered with cotton cloth for connecting with the longitudinal exercise belt 1, the wrapping belt 2, the storage bag 3, and the transverse exercise belt 6.

[0044] Both the longitudinal exercise belt 1 and the transverse exercise belt 6 are made of flexible material; specifically, both the longitudinal exercise belt 1 and the transverse exercise belt 6 are made of cotton cloth.

[0045] Both the longitudinal exercise belt 1 and the transverse exercise belt 6 are equipped with length adjustment buckles (not shown in the figure). These length adjustment buckles are existing technology and this technical solution does not improve upon them. For example, the length adjustment buckles are the adjustment buckles of backpack straps.

[0046] Specifically, such as Figure 1 As shown, the longitudinal exercise belt 1 is positioned at the top of the foot support pad 5, and the fixed end of the longitudinal exercise belt 1 is fixedly connected to the foot support pad 5. The free end of the longitudinal exercise belt 1 is equipped with a pull ring for the patient to grip. The longitudinal exercise belt 1 and the foot support pad 5 are integrally connected.

[0047] like Figure 1-2 As shown, two transverse exercise belts 2 are respectively set on both sides of the foot support pad 5, and the fixed end of the transverse exercise belt 2 is fixedly connected to the foot support pad 5. Similar to the longitudinal exercise belt 1, the free end of the transverse exercise belt 2 is provided with a pull ring; wherein, the transverse exercise belt 2 is integrally connected to the foot support pad 5.

[0048] like Figure 3 As shown, the wrapping strap 2 is positioned on the side of the foot support pad 5 away from the patient's foot, and is used to connect the longitudinal exercise strap 1 or the transverse exercise strap 6. The wrapping strap 2 is an elastic band.

[0049] Specifically, the wrapping strap 2 includes an ankle fixation part 21 and two instep fixation parts 22. The end of each instep fixation part 22 is connected to the foot support pad 5, and the side of the instep fixation part 22 near the ankle fixation part is connected to the ankle fixation part 21. Both the ankle fixation part 21 and the instep fixation part 22 are elastic bands. In use, the ankle fixation part 21 wraps around the patient's ankle while the instep fixation parts 22 fix the patient's foot to the foot support pad 5.

[0050] In practical applications, patients can use the movable end of the transverse exercise band 6 to move their lower limbs left and right, or they can use the movable segment of the longitudinal exercise band 6 to raise or lower their lower limbs, thus achieving lower limb exercise in the vertical direction.

[0051] For easy storage, such as Figure 1 As shown, a storage strap 3 is provided on the side of the foot support pad 5 away from the patient's foot. The storage strap 3 is an elastic bag with a length adjustment buckle. The storage strap 3 is used to store the longitudinal storage strap 1 or the transverse storage strap 6 when the patient is performing lower limb rehabilitation exercises, so as to prevent the longitudinal storage strap 1 or the transverse storage strap 6 from falling off and interfering with the patient's rehabilitation exercises.

[0052] In actual use, patients can first roll the longitudinal exercise band 1 or the transverse exercise band 6 into a cylindrical structure, and then use the storage band 3 to fix the longitudinal exercise band 1 or the transverse exercise band 6 to the foot support pad 5.

[0053] A reinforcing plate 4 is also provided on the storage strap 3, which is set on the foot support pad 5 and crosses the storage strap 3. The lower end of the reinforcing plate 4 is fixedly connected to the foot support pad 5, and the upper end of the reinforcing plate 4 is detachably connected to the foot support pad 5. Specifically, the upper end of the reinforcing plate 4 is connected to the foot support pad 5 by Velcro. In this way, after the storage strap 3 fixes the longitudinal exercise strap 1 or the transverse exercise strap 6 to the foot support pad 5, the movable end of the reinforcing plate 4 can be fixed to the foot support pad 5, which can further prevent the transverse or longitudinal exercise strap from falling off.

[0054] The reinforcing plate 4 is made of flexible material; specifically, the material of the reinforcing plate 4 is cotton cloth.

[0055] Specifically, the foot support pad 5 has a Velcro surface on one side and the other side of the reinforcing plate 4, and the free end of the reinforcing plate 4 has a Velcro hook surface, so as to fix the longitudinal exercise belt 1 between the foot support pad 5 and the reinforcing plate 4.

[0056] The stabilizing plate 7 has a plate-like structure, such as Figure 6 As shown, the stabilizing plate 7 includes a foot base 71 and a fish tail portion 72, wherein the foot base 71 and the fish tail portion 72 are integrally connected. Specifically, the stabilizing plate 7 is made of a rigid material. It should be noted that this embodiment of the utility model does not limit the material of the stabilizing plate 7; for example, the stabilizing plate 7 is made of plastic.

[0057] The foot sole 71 has a square structure to match and fit with the receiving cavity of the foot support pad 5. The foot sole 71 is used to provide horizontal support for the patient's foot to facilitate rehabilitation exercises.

[0058] The fish tail 72 has a trapezoidal structure. When in use, the patient's foot can be slightly lifted up so that the foot is off the bed. In this way, when the patient moves the affected limb horizontally for rehabilitation exercises, the fish tail 72 provides vertical support for the affected limb. Moreover, because the fish tail 72 has a trapezoidal structure, the length of the base of the fish tail 72 is greater than the width of the foot support pad 5, which can effectively prevent the patient's ankle from rotating.

[0059] The bottom edge of the fish tail 72 is wider than the width of the foot support pad 5. This ensures the stability of the stabilizing plate 7 during use and effectively prevents the patient's foot from rotating.

[0060] In actual use, the foot support pad 5 is fitted onto the stabilizing plate 7, and the bottom of the foot 71 is located inside the receiving cavity of the foot support pad 5, while the fish tail 72 is located outside the receiving cavity of the foot support pad 5.

[0061] The footrest 71 provides horizontal support to the patient's foot, while the bottom of the fishtail 72, located below the foot support pad, provides vertical support. This allows the patient's ankle to be slightly raised under the support of the fishtail 72, lifting the foot off the bed surface. This helps maintain the patient in an abducted, neutral position during non-exercise periods, preventing foot drop, pressure sores, and other complications. Furthermore, when the patient performs horizontal translation exercises, the fishtail 72 provides vertical support, preventing internal or external rotation of the foot during rehabilitation exercises, thus stabilizing the affected limb joint and promoting recovery.

[0062] A fixing rope 8 is provided at the bottom of the foot support pad 5, such as... Figure 1 As shown, one end of the fixing rope 8 is fixedly connected to one side of the foot support pad 5, and the other end is connected to the other side of the foot support pad 5 via a button. Thus, after the stabilizing plate 7 is inserted into the receiving cavity of the foot support pad 5, the fixing rope 8 can be wrapped around the bottom end of the stabilizing plate 7 and connected to the foot support pad 5, preventing the stabilizing plate 7 from falling out of the receiving cavity of the foot support pad 5. When it is necessary to separate the foot support pad 5 from the stabilizing plate 7, the end of the fixing rope 8 with the button hole is separated from the button on the foot support pad 5, thus completing the separation of the foot support pad 5 from the stabilizing plate 7.

[0063] Application examples:

[0064] Mr. Liu, 56 years old, needs to undergo lower limb rehabilitation exercises after hip joint surgery;

[0065] Step 1: Insert the end of the stabilizing plate 7 with the foot 71 into the receiving cavity of the foot support pad 5;

[0066] Step 2: Place the foot support pad 5 under the patient's feet and let the patient's feet pass through the wrapping strap 2;

[0067] Step 3: As Figure 4 As shown, the horizontal exercise belt 6 is stored and then fixed to the foot support pad 5 by the storage strap 3;

[0068] Step 4: Connect the upper end of the reinforcing plate 4 to the foot support pad 5 to further secure the transverse exercise belt 6;

[0069] Step 5: The patient pulls the hand rings set on the free end of the longitudinal exercise belt 1 to raise or lower the lower limbs, thereby achieving rehabilitation exercises in the vertical direction;

[0070] Step Six: After completing the vertical rehabilitation exercises, untie the storage strap 3, as follows: Figure 5 As shown, the longitudinal exercise belt 1 is fixed between the storage belt 3 and the foot support pad 5;

[0071] Step 7: Connect the upper end of the reinforcing plate 4 to the foot support pad 5 to further secure the longitudinal exercise belt 1;

[0072] Step 8: The patient pulls the hand rings set on the free end of the transverse exercise belt 6 to move the lower limbs and achieve rehabilitation exercises in the horizontal direction.

[0073] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
