Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a foot drop rehabilitation massage boot. Background Technology

[0002] Stroke is characterized by high incidence, high mortality, high disability rate, high recurrence rate, and numerous complications. Foot drop is one of the most common complications in stroke patients, especially the elderly. The typical manifestation of stroke-related foot drop is significant weakness in ankle and toe dorsiflexion. Because the patient's foot cannot fully and stably contact the ground, the risk of falls and sprains is greatly increased, which is a serious injury, even potentially fatal, for elderly patients. Currently, the focus of rehabilitation for stroke-related foot drop is to help patients improve muscle strength to the greatest extent possible and restore limb motor function. Compared to traditional physical therapy and drug treatment, traditional Chinese medicine acupressure has advantages such as low cost and no side effects.

[0003] Massage products, both domestically and internationally, can be broadly categorized into two types based on size and convenience: large intelligent massage devices and small, portable massage products. Large intelligent massage products primarily utilize spatial magnetic fields and mechanical vibrations to simulate techniques such as kneading, patting, and rolling massage employed by massage experts. Small massage products, on the other hand, often employ roller vibrations, 3D massage beads, textured surfaces, and techniques mimicking real massage to achieve their therapeutic effects. However, currently, few rehabilitation products for stroke patients on the market combine foot drop prevention with traditional Chinese medicine acupressure massage.

[0004] Utility model CN214802744U discloses an automatic massage shoe for acupoints on the sole of the foot, including an upper, a sole plate, a controller, two first motors, a massage top rod, two gears, and a slide. A groove is formed in the middle of the sole plate; the slide is slidably disposed within the groove; the massage top rod includes a massage head and a meshing part; the massage head is fixed to the top of the meshing part; a locking tooth is provided on the outer wall of the meshing part; the gears mesh with the locking teeth; the massage top rod is vertically movable on the slide via the gears and locking teeth; the two first motors are respectively connected to the two gears; the controller is disposed inside the sole plate; the controller is electrically connected to the two first motors. This utility model of automatic massage shoe mainly targets a specific acupoint and does not involve acupoint massage on the dorsum of the foot, resulting in an insignificant massage effect. Furthermore, the massage mode is relatively simple, and the massage intensity cannot be controlled independently, posing a risk of skin injury. The fixed shoe design significantly restricts foot eversion and inversion; if the patient experiences foot spasms and is unable to move, there may be a risk of difficulty in putting on the shoe. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a foot drop rehabilitation massage boot.

[0006] This utility model discloses a foot drop rehabilitation massage boot, comprising: a shoe shaft, the shoe shaft including a flexible front side and a rigid rear side connected to each other, the two flexible front sides being connected by a shoelace; a rotating assembly, one end of the rotating assembly being connected to the shoe shaft and the other end being mounted on the shoe upper; a transmission assembly, the transmission assembly being mounted in the internal cavity of the sole; a movable massage assembly, the movable massage assembly being located in the internal cavity of the sole and cooperating with the transmission assembly; a fixed massage assembly, the fixed massage assembly being mounted on the inner wall of the top of the shoe upper; and a thin-film resistive pressure sensor, the thin-film resistive pressure sensor being mounted on the movable massage assembly and the fixed massage assembly.

[0007] The rotating assembly includes a rotating plate fixedly connected to the shoe shaft, the other end of the rotating plate being fixedly connected to the upper side of a gear, the gear being mounted on the outside of the shoe upper via a mounting plate, the gear meshing with a rack, the other end of the rack being fixedly connected to the output shaft of a motor, the motor and the controller being housed in a controller housing, the controller housing being located on the outside of the shoe upper below the mounting plate.

[0008] The transmission assembly includes a transmission plate, which is placed on top of four transmission plate supports. The transmission plate supports are fixed in the sole of the shoe. Limiting plates extend downward from both ends of the transmission plate. Protrusions are spaced apart on the upper part of the transmission plate. A rack is installed along the length direction in the middle of the bottom of the transmission plate.

[0009] The rack and pinion 2 mesh with the gear 2, the gear 2 is coaxially arranged with the motor 2, and the gear 2 and the motor 2 are installed between the four transmission plate supports of the shoe sole.

[0010] The top of the transmission plate support is hemispherical, and the limiting plate is located outside the transmission plate support.

[0011] There are three protrusions, two at the front end and one at the rear end. The front and rear protrusions are arranged along the length of the transmission plate and are stepped.

[0012] The sole and the inner cavity of the shoe are separated by a partition. A through hole is provided in the middle of the partition, corresponding to the position of the protrusion. A movable massage component is installed in the through hole.

[0013] The active massage component includes a housing fixedly connected to a partition. The upper part of the housing is fixedly connected to the partition.

A massage head two is provided on the top of the connecting rod two. A thin-film resistive pressure sensor is covered on the massage head two.

[0016] The beneficial effects of this invention are that it combines traditional Chinese medicine with ergonomics, integrating TCM theory and utilizing the principles of vibration massage and biomechanics to combine foot drop prevention with foot acupoint massage. It employs multi-acupoint massage on the soles and dorsum of the foot, with three intensity levels: weak, medium, and strong. The ankle joint can rotate at multiple angles and automatically perform ankle pump exercises to train the foot muscles. A mechanical structure supports and corrects the patient's foot. Through a 90° vertical rotating component that can rotate forward and backward, in cases of sudden foot spasms and inability to move, the patient's foot is first relieved through local massage to restore it to a normal or near-normal position before shoes are put on. Simultaneously, the massage of relevant acupoints stimulates blood circulation and nerve conduction, thereby improving gait, preventing muscle atrophy, and further promoting nerve recovery. Furthermore, the product is equipped with a thin-film resistive pressure sensor to monitor the pressure of the massage ball and can automatically adjust the pressure to a level tolerable for the patient.

Detailed Implementation

[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1-10As shown, the foot drop rehabilitation massage boot of this utility model includes: a shoe shaft 1, a rotating component 2, a transmission component 7, a movable massage component 5, a fixed massage component 9, and a thin-film resistive pressure sensor. The shoe shaft 1 includes a flexible front side 101 and a rigid rear side 102 that are connected to each other. The two flexible front sides 101 are connected by a shoelace 103. The flexible front side 101 is made of a soft material to provide comfort, and the rigid rear side 102 is made of a rigid material to enhance the stability of the ankle joint and better control the rotation of the shoe shaft. One end of the rotating component 2 is connected to the shoe shaft 1, and the other end is installed on the shoe upper. The rotating component 2 is used to control the rotation of the shoe shaft 1. The transmission component 7 is installed in the internal cavity of the shoe sole 3. The movable massage component 5 is located in the internal cavity of the shoe sole 3, and the movable massage component 5 cooperates with the transmission component 7. The movable massage component 5 is used to massage the acupoints on the sole of the foot, and the transmission component 7 is used to control the massage level of the movable massage component 5. The fixed massage component 9 is installed on the inner wall of the top shoe upper 8. The fixed massage component 9 is used to massage the instep. The thin-film resistive pressure sensor is installed on the movable massage component 5 and the fixed massage component 9. The thin-film resistive pressure sensor is used to monitor and provide feedback on the massage intensity in real time and adjust the massage intensity in real time to achieve precise adjustment of the massage intensity.

[0031] The rotating assembly 2 includes a rotating plate 201 fixedly connected to the shoe shaft 1. The other end of the rotating plate 201 is fixedly connected to the upper side of a gear 202. The gear 202 is mounted on the outer side of the shoe upper 8 via a mounting plate 205. Specifically, the rotating plate 201 is fixedly connected to the rigid rear side 102 on the shoe shaft 1 by bolts, and the mounting plate 205 is mounted on the outer side of the shoe upper 8 below the rigid rear side. The gear 202 meshes with a rack 203, the other end of which is fixedly connected to the output shaft of a motor 206. The motor 206 and the controller 204 are housed in a controller housing located on the outer side of the shoe upper 8 below the mounting plate 205. The motor 206 is a linear motor; its output shaft drives the rack 206 to move linearly. The movement of the rack 203 drives the gear 202 to rotate, which in turn drives the shoe shaft 1 to rotate, thus enabling ankle pumping through the shoe shaft 1.

[0032] The controller housing has two buttons: a massage level button and power switches for motors 206 (1), 505 (2), and 903 (3). These buttons are connected to the controller 204, which in turn connects to each of the motors. The controller 204 controls the massage level buttons and the on / off switches of the motors. An infrared remote control is also connected to the controller 204 for remote control.

[0033] The transmission assembly 7 includes a transmission plate 701, a limiting plate 702, a transmission plate support 703, a second gear 705, and a second rack 704. The transmission plate 701 is placed on top of the four transmission plate supports 703, which are fixed in the sole 3. Limiting plates 702 extend downwards from both ends of the transmission plate 701 and are located outside the transmission plate supports 703. The limiting plates 702 prevent the transmission plate 701 from slipping during movement, ensuring the stability of the shoe. The top of the transmission plate support 703 is hemispherical, which reduces friction during the movement of the transmission plate. The four transmission plate supports 703 are located at the four corners of the bottom of the transmission plate 701, making the transmission process of the transmission plate 701 more stable.

[0034] A rack 704 is mounted along the length of the bottom center of the transmission plate 701. The rack 704 meshes with a gear 705, which is coaxially mounted with a motor. The gear 705 and the motor are installed between the four transmission plate supports 703 of the shoe sole 3. The output shaft of the motor drives the gear 705 to rotate, which in turn moves the rack 704. The movement of the rack 704 then moves the transmission plate 701.

[0035] The transmission plate 701 is provided with protrusions 6 at intervals on the upper part. The protrusions 6 are fixed to the transmission plate 701 by bolts or adhesive. The movement of the transmission plate 701 can drive the protrusions 6 to move. There are three protrusions 6, two at the front end and one at the rear end of the transmission plate 701. The protrusions 6 at the front end and the rear end are arranged at intervals along the length of the transmission plate 701, and the protrusions 6 are stepped.

[0036] The sole 3 is separated from the inner cavity of the shoe by a partition 4. A through hole is provided in the middle of the partition 4 at the position corresponding to the protrusion 6, and a movable massage component 5 is installed in the through hole.

[0037] like Figures 6-9 As shown, the active massage component 5 includes a housing 501, a lifting platform 502, a third motor 505, springs 507, a first connecting rod 504, and a first massage head 503. The upper part of the housing 501 is fixedly connected to the partition 4. The bottom of the housing 501 is open, and a group of U-shaped holes for protrusions 6 to pass through are provided on the lower part of a set of sides of the housing 501 at intervals along the length of the transmission plate 701. The lifting platform 502 is connected to the inside of the housing 501 by at least two springs 507. The side of the lifting platform 502 facing the U-shaped hole is provided with a buffer slope 506. The springs 507 are installed on the top of the lifting platform 502. The third motor 505 is installed inside the lifting platform 502. The output shaft of the third motor 505 is connected to the first connecting rod 504. The first massage head 503 is provided on the top of the first connecting rod 504. A thin-film resistive pressure sensor is attached to the first massage head 503.

[0038] The output shaft of motor 3 505 is fixedly connected to connecting rod 1 504. Motor 3 505 will drive massage head 1 503 to vibrate, thereby massaging the soles of the feet.

[0039] When the transmission plate 701 drives the protrusion 6 through the U-shaped hole below the housing 501, it will first contact the buffer slope 506 of the lifting platform 502. As the protrusion 6 continues to move, it will press the lifting platform 502 upward. Since the protrusion 6 has three steps, the protrusion 6 presses the lifting platform 502 upward in three levels. These three levels are different from the contact force of the sole of the foot, so the massage head 503 has three massage levels. The cooperation between the protrusion 6 on the transmission plate 701 and the lifting platform 502 in the movable massage assembly 5 is used to control the lifting and lowering of the motor 505, thereby adjusting the massage intensity.

[0040] like Figure 10 As shown, the fixed massage component 9 includes a motor 4 903 installed on the inner wall of the shoe upper. The output shaft of the motor 4 903 is connected to the connecting rod 2 901. A massage head 2 902 is provided on the top of the connecting rod 2 901. A thin film resistive pressure sensor is covered on the massage head 2 902.

[0041] Motor 4 903 will drive the vibration of massage head 2 902, thereby massaging the instep.

[0042] Both motor 3 (505) and motor 4 (903) are DC brushless motors. Massage head 1 (503) and massage head 2 (902) can be either one large massage head or multiple small massage heads.

[0043] The first foot massage head 503 is mainly located near the Yongquan acupoint, the Liniting acupoint, and the heel. The second foot massage head 902 is located near the Taichong acupoint and the Zhongfeng acupoint.

[0044] When using this invention, if a foot drop patient experiences sudden foot cramps during rehabilitation and is unable to move, they will be unable to put on the device using normal shoe-wearing methods. In this case, the shoelaces 103 between the two flexible front sides 101 of the shoe shaft 1 can be untied, opening the shoe shaft 1. The rotating component 2 can be adjusted to the angle and shape formed by the patient's foot, allowing the patient's foot to be easily put into the shoe. Then, the vibration and rotation of the massage ball 902 at the Zhongfeng acupoint promotes contact with the foot cramps, enabling the patient to move their foot (non-actively). The movement of the massage shoe can be controlled by an infrared remote control, such as adjusting the rotating component 2 to induce ankle pump exercises (pushing the patient to flex their foot and hold for 3-5 seconds, then pushing the patient to point their foot for 3-5 seconds, repeating this process), or the massage mode (vibration, rotation, etc.) can be controlled by the infrared remote control, and the massage intensity can be selected by the user. The optimal massage intensity can be set by the infrared remote control. Subsequently, the foot pressure sensor will monitor the pressure and automatically adjust the intensity of the massage ball to achieve the best massage effect.
