Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment for patients with foot drop, and in particular to a rehabilitation equipment for preventing foot drop in patients with hemiplegia. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, some cardiovascular and cerebrovascular diseases are gradually becoming younger. The disease is fierce. Even if the life is saved, the unfavorable rehabilitation in the later stage will still leave many inconveniences and psychological shadows for the patient. This product can effectively help patients with coma or hemiplegia and paraplegia caused by stroke, brain trauma, cerebrovascular accident, etc. due to long-term bed rest and cause foot drop. The initial concept of foot drop was formed as a complication caused by damage to the central nervous system, reflex sympathetic dystrophy, and neurovascular atrophy. Later, through a large number of related experiments and clinical studies, it was proposed that the disease is related to changes in the physical properties of muscle fibers and tendons, and is likely to be related to braking and disuse. Therefore, in the intensive care unit, more and more clinicians pay attention to the rehabilitation of critically ill patients, from the initial early bed activities to the passive electrical stimulation activities and other rehabilitation training for paralyzed patients who have not recovered consciousness.

[0003] Medical staff choose corresponding rehabilitation and correction methods for patients with foot drop, but this method takes a long time to treat and consumes a lot of manpower. There is also a method of wearing foot assistive devices to fix the foot position to restore the foot position to normal, but this type of foot assistive device is basically a fixed assistive device, which cannot adjust the angle of the foot assistive device required for the rehabilitation of patients with foot drop, thereby reducing the range of people who can use the foot assistive device.

[0004] In order to facilitate the adjustment of the angle of the foot assistive device, a Chinese patent with application number CN202323040437.1 discloses a foldable foot drop rehabilitation device, including an ankle front plate, an ankle back plate, a foot plate and a foot sole plate. The front ankle plate and the foot plate are rotatably connected near the end and the angle of the front ankle plate and the foot plate can be adjusted. An abdominal belt is provided between the front ankle plate and the ankle back plate, and between the foot plate and the foot sole.

[0005] Although the above patent can solve the problem of angle adjustment of the foot assistive device, it is necessary to manually rotate the nuts and bolts during the adjustment process to achieve the angle adjustment of the front plate of the ankle and the foot plate. The above operation process is cumbersome, and manual adjustment results in low accuracy of the angle adjustment of the foot assistive device, which is not conducive to targeted treatment of patients and slows down the patient's recovery process.

[0006] Therefore, a rehabilitation device for preventing foot drop in hemiplegic patients has become an urgent problem to be solved by the whole society. Summary of the invention

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a rehabilitation device for preventing foot drop in hemiplegic patients, comprising a sole support plate and a calf support plate, wherein the heel of the sole support plate is movably connected to the bottom of the calf support plate through a first spherical shaft device, a second spherical shaft connection device is provided on one side of the sole support plate, and a third spherical shaft connection device is provided on the other side thereof;

The first shielding protection part is movably connected to the bottom of one side of the calf support plate through a second spherical shaft connecting device, and the second shielding protection part is movably connected to the bottom of the other side of the calf support plate through a third spherical shaft connecting device.

[0009] The first spherical shaft device, the second spherical shaft device and the third spherical shaft device have the same structure. The first spherical shaft device includes an intermediate connecting rod, a first spherical connector is provided at one end of the intermediate connecting rod, and a second spherical connector is provided at the other end thereof. A plurality of first engaging grooves matching the first spherical connector are provided at the rear side of the heel of the sole support plate, and a plurality of second engaging grooves matching the second spherical connector are provided at the bottom of the calf support plate.

[0011] Furthermore, a sole lining interlayer is provided in the sole support plate, and the sole lining interlayer is fixed to the inner side of the sole support plate by Velcro bonding, and the sole lining interlayer is made of latex material or cotton pad material.

[0012] Furthermore, a sole liner Velcro bonding area is provided at the edge of the sole liner interlayer to facilitate bonding and fixing of the sole liner interlayer.

[0013] Furthermore, a sole fixing strap is provided on the sole supporting plate for binding and fixing the sole of the foot.

[0014] The advantages of the invention compared with the prior art are:

[0015] The present invention adopts a combination of multiple structures such as a sole support plate, a calf support plate, a first spherical shaft device, a second spherical shaft connection device and a third spherical shaft connection device, and uses a computer program stored on a computer-readable storage medium to accurately adjust the angle between the sole support plate and the calf support plate, thereby solving the problem of low accuracy in the prior art of manually adjusting nuts and bolts. Through the above technical solution, ROM training of lower limb massage training can be performed on paralyzed patients. According to the training basis, the product is used to assist the patient in performing sufficient joint flexion and joint extension activities, so that the joint capsule and the tendons around the joints are fully stretched.

[0016] The product designed by the present invention can be effectively applied to various hemiplegic patients for early rehabilitation training to prevent foot drop, and for rehabilitation training to improve foot drop in the middle and late stages, and can still be used for health training of daily bipedal activities in the recovery stage.

[0031] Example:

[0032] Before rehabilitation of hemiplegic patients with foot drop, the foot drop assessment is based on GREEN and is divided into the following levels after scoring:

[0033] Take the left foot as an example, with the vertical direction as the longitudinal axis A and the horizontal direction as the transverse axis B. Line B is the horizon and parallel to the ground, and is the straight line where the sole of the foot touches the ground:

[0034] With reference to the attached drawings, the neutral position ∠AOB=90°.

[0035] The activity trajectory of adjusting plantar flexion and extension of the sole of the foot is shown as the circular solid line in the figure:

[0036] Plantar flexion angle is ∠BOB1

[0037] The extension angle is ∠BOB2

[0038] Adjust the ankle joint to move left and right as shown by the elliptical dotted line in the figure:

[0039] The left angle is ∠BOB3

[0040] The right angle is ∠BOB4

[0041] Function 1 and function 2 are adjusted to ∠BOB1 or ∠BOB2, and perform counterclockwise and clockwise movements after setting the angle.

[0042] Excellent: normal appearance, plantar walking; passive ankle movement at least 10 degrees beyond neutral, and active return to neutral; plantar flexion greater than 20 degrees, unrestricted activities including various competitions. No pain during or after activities; at least half of the range of motion of the talocerecal joint, normal midtarsal joint movement.

[0043] Good: Slight heel inversion, the forefoot can be flexibly adducted, enough to accommodate normal activities without discomfort; at least dorsiflexion to neutral position, plantar flexion <10 degrees. The talocerecal joint has at least half range of motion, and the midtarsal joint is flexible. Future soft tissue surgery will definitely not affect the above functions.

[0044] Poor: more obvious heel varus, or accompanied by slight fixed adduction deformity of the forefoot; limited ankle joint movement, with range of motion <10 degrees in all directions.

[0045] After the judgment is completed, the patient is put on the above rehabilitation device, the patient's foot fits the foot support plate 1, and the calf support plate 2 fits the patient's leg

[0046] The present invention sets three levels of gears for the rehabilitation device for the above three levels of patients:

[0047] Level 1: Adjust the ankle joint passive motion to the left 5° for 5 seconds, center for 5 seconds, right 5° for 5 seconds, center for 5 seconds. Plantar flexion 5° for 5 seconds, center for 5 seconds, extension 5° for 5 seconds, center for 5 seconds. One cycle is 40 seconds. A total of 30 minutes, do 45 cycles, twice a day.

[0048] Level 2: Adjust the ankle joint passive activity to the left 10° for 5 seconds, center 5 seconds, right 10°, center 5 seconds. Plantar flexion 10° for 5 seconds, center 5 seconds, extension 10° for 5 seconds, center 5 seconds. One cycle is 40 seconds, continuous training for 30 minutes, 45 cycles, training twice a day.

[0049] Level 3: Adjust the passive movement of the ankle joint to the left 20° for 5 seconds, center for 5 seconds, right 20°, center for 5 seconds. Plantar flexion 20° for 5 seconds, center for 5 seconds, extension 20° for 5 seconds, center for 5 seconds. One cycle is 40 seconds, continuous training for 30 minutes, 45 cycles, training twice a day.

[0050] There are two functional gears for this product:

[0051] Function 1: After the feet are naturally centered, plantar flexion is 10°. According to the working principle of the spherical axis, the joints of the feet are rotated counterclockwise for 15 minutes, and then rotated clockwise for 15 minutes;

[0052] Function 2: After both feet are naturally centered, plantar flexion is performed 20°. According to the working principle of the spherical axis, the joints of both feet are rotated counterclockwise for 15 minutes, and then rotated clockwise for 15 minutes.

[0053] There are two working modes for this product:

[0054] A mode: control mode, complete all the above training operations according to product control; the maximum safety angle for A mode is set to 30°, so the maximum angle of A mode during operation is <30°.

[0055] B mode: autonomous mode, based on the working principle of the spherical axis, the above training operations are completed actively according to the autonomous needs of some awake patients, without the need for program control. The maximum angle of autonomous completion set in B mode is 30°.

[0056] When the present invention is in use, the sole support plate can be designed into different sizes as needed to meet the use requirements, wherein the design is based on the length of the sole: small size 35-37, medium size 38-40, large size 41-43, and then it can be tied and fixed with a strap.

[0057] Embodiment 2:

[0058] A sole lining interlayer 10 is provided in the sole support plate 1. The sole lining interlayer 10 is fixed to the inner side of the sole support plate 1 by Velcro bonding. The sole lining interlayer 10 is made of latex material or cotton pad material. A sole lining Velcro bonding area 12 is provided at the edge of the sole lining interlayer 10 to facilitate bonding and fixing the sole lining interlayer. A sole fixing strap 13 is provided on the sole support plate 1 to bind and fix the sole of the foot.

[0059] A calf lining interlayer 11 is provided in the calf support plate 2, and the calf lining interlayer 11 is fixed to the inner side of the calf support plate 2 by Velcro bonding, and the calf lining interlayer 11 is made of latex material or cotton pad material.

Two groups of calf fixing straps 15 are provided on the calf support plate 2 to support and fix the calf.

[0060] When the present invention is in use, a sole lining partition 10 is installed in the sole support plate 1, and a calf lining partition 11 is installed in the calf support plate 2. Since the above-mentioned sole lining partition 10 and the calf lining partition 11 are made of latex material or cotton pad material, when the patient uses the foot rehabilitation device, the patient's skin contacts the partition, which increases the patient's comfort during the foot rehabilitation process.

[0061] Wherein, a computer program is stored on the computer-readable storage medium, and when the computer program is run by the processor, it is executed to set the angle of a rehabilitation device for preventing foot drop in hemiplegic patients. The above program can replace the manual rehabilitation teacher to perform bipedal Rom training, and the above program can control the spherical axis to run to the set angle and pause for the set time, and then reset. When in use, the structure of the adjustment panel can also be added, and the angle adjustment of the above rehabilitation device can be adjusted by the buttons on the adjustment panel. The above adjustment panel control method is a technical means well known and commonly used by those skilled in the art, and the applicant will not elaborate on it.

[0062] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
