Description

Technical Field

[0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular is a rehabilitation mat for monitoring plantar pressure distribution. Background Art

[0002] Rehabilitation therapy is an indispensable and important part after orthopedic surgery, and plays a vital role in the patient's recovery and functional reconstruction. For example, the core of rehabilitation after ankle fracture internal fixation, total knee replacement, and calcaneal fusion surgery lies in progressive weight-bearing training. Clinical studies have shown that 2-6 weeks after surgery is the critical period for bone healing.

[0003] Importance of rehabilitation therapy:

[0004] Promote healing: After orthopedic surgery, bones, muscles, ligaments and other tissues need time to heal. Rehabilitation therapy can promote local blood circulation, accelerate metabolism, and provide good nutrition and environment for tissue healing.

[0005] Restoring function: Although surgery solves the problem of orthopedic diseases, it often leads to functional disorders such as joint stiffness, muscle atrophy, and limited movement. Rehabilitation therapy can help patients gradually restore joint mobility, increase muscle strength, and improve body coordination, thereby restoring daily life and work ability.

[0006] Prevent complications: After orthopedic surgery, patients are prone to complications such as deep vein thrombosis, lung infection, and urinary tract infection due to prolonged bed rest or immobilization. Rehabilitation therapy can effectively prevent the occurrence of these complications through early activities, breathing training, bladder function training and other measures.

[0007] However, existing traditional rehabilitation methods rely on doctors, who mainly judge the weight-bearing status of the affected limb through visual inspection and hand palpation. Especially for obese patients or diabetic patients with sensory nerve damage, the reliability of subjective assessment is significantly reduced, increasing the error rate.

[0008] There are also devices that assist patients in rehabilitation, such as weight-bearing shoes, but the smart weight-bearing shoes on the market are relatively bulky and cannot adapt well to different rehabilitation patients, affecting the rehabilitation effect. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention provides a plantar pressure distribution monitoring rehabilitation mat to solve the problems in the prior art such as unsatisfactory results in the weight-bearing rehabilitation process of orthopedic patients after surgery.

[0010] A rehabilitation mat for monitoring plantar pressure distribution includes a rehabilitation mat body, acupressure balls spaced apart on the top of the rehabilitation mat body, a pressure sensor connected to an external power supply disposed inside the acupressure balls, a detection end of the pressure sensor exposed above the acupressure balls, a detachably connected load-bearing frame disposed at the bottom of the rehabilitation mat body, and a blood circulation component disposed inside the load-bearing frame.

[0011] Preferably, the rehabilitation mat is made of a flexible material, and three areas are formed on the rehabilitation mat: a precision control training area, a stable transition area, and a functional recovery area. There is an area line engraved on the top of the rehabilitation mat between each area, and the stable transition area is located between the precision control training area and the functional recovery area.

[0012] Preferably, the acupressure ball is made of silicone material, the vertical cross-section profile of the acupressure ball is a hemisphere, the acupressure ball is fixedly connected to the rehabilitation mat and distributed in an array, and the number of the acupressure balls arranged gradually decreases from the precision control training area toward the functional recovery area.

[0013] Preferably, a detachably connected cleaning pad is provided on the top of the rehabilitation mat body, and there are three cleaning pad bodies, which are respectively located on the top of the precision control training area, the stable transition area and the functional recovery area. Hook stickers are provided at intervals on the bottom of the cleaning mat body and near the edges. A fleece sticker is provided on the top of the rehabilitation mat body, which is opposite to the hook sticker, and the hook sticker and the fleece sticker are adhered to each other.

[0014] Preferably, each of the rehabilitation pads is provided with through holes distributed in an array, the positions of the through holes cooperate with the acupressure balls, and the top of the cleaning pad is provided with anti-slip ridges distributed at intervals. The anti-slip ridges are made of silicone material, and the cross-sectional profile of the anti-slip ridge is "X"-shaped and is located between two adjacent acupressure balls.

[0015] Preferably, alarms are provided at intervals on the top of the rehabilitation mat. There are three alarms, which are respectively located in the precision control training area, the stable transition area and the functional recovery area. Text identification areas are provided on both sides of the precision control training area, the stable transition area and the functional recovery area.

[0016] Preferably, a fixedly connected protection pad is provided at the bottom of the rehabilitation pad, the protection pad is made of the same material as the rehabilitation pad, and the bottom of the protection pad is provided with anti-slip stripes distributed at intervals.

[0017] Preferably, the vertical cross-sectional profile of the load-bearing frame is "concave", and a bearing groove is provided on the top of the load-bearing frame. The height of the bearing groove is less than the height of the rehabilitation pad and the protection pad. The blood circulation component includes a heating element, a thermal insulation element, an electric wire and a plug. The thermal insulation element is located on the inner bottom end of the load-bearing frame, and the heating element is located on the top of the thermal insulation element. The heating element adopts a graphene heating method. One end of the electric wire is connected to the heating element, and the other end extends out of the load-bearing frame. The plug is fixedly connected to the other end of the electric wire.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a rehabilitation mat with spaced acupressure balls on top. Pressure sensors connected to an external power supply are installed inside the acupressure balls. The pressure sensors are micro-thin film pressure sensors. When the patient steps on the rehabilitation mat with a weight, the tops of the acupressure balls are smooth, which can avoid puncturing the skin and effectively stimulate the acupuncture points and reflex areas on the soles of the feet.

[0020] Moreover, the detection end of the pressure sensor is exposed on the top surface of the acupressure ball. When the patient steps on the acupressure ball, the pressure sensor can directly sense the pressure exerted on the sole of the foot. All pressure sensors are connected to the bus inside the rehabilitation mat through built-in wires, and finally collected into the data processing unit, finally forming a real-time sole pressure distribution map, which helps patients make timely adjustments, improves the patient's postoperative rehabilitation training effect, and avoids injuries caused by incorrect posture.

[0021] 2. The present invention provides a comprehensive foot rehabilitation solution by perfectly integrating real-time monitoring of plantar pressure distribution, acupoint acupressure stimulation, graphene thermal therapy to activate blood circulation, scientific zoning rehabilitation training guidance (precision control, transition, recovery), and instant safety alarm functions into a single floor mat product.

The present invention adopts a three-zone design based on rehabilitation needs, namely "precision training zone - stable transition zone - functional recovery zone", combined with the density gradient distribution of acupressure balls, to guide users to conduct targeted and progressive rehabilitation training, in line with rehabilitation rules and improve training efficiency.

[0023] 4. The present invention can obtain high-resolution spatiotemporal distribution data of plantar pressure through array-type distributed built-in pressure sensors, especially the high-density distribution in the precision-controlled training area, providing a solid data basis for objectively evaluating the functional status of the foot, balance ability, gait characteristics and rehabilitation effects.

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] As attached Figure 1 To the attached Figure 6 As shown:

[0034] Embodiment 1: The present invention provides a rehabilitation mat for monitoring plantar pressure distribution, comprising a rehabilitation mat body 1, acupressure balls 2 spaced apart on the top of the rehabilitation mat body 1, a pressure sensor 3 with an external power supply provided inside the acupressure ball 2, a detection end of the pressure sensor 3 exposed to the acupressure ball 2, a detachably connected load-bearing frame 4 provided at the bottom of the rehabilitation mat body 1, a blood circulation component provided inside the load-bearing frame 4.

[0035] It should be noted that a rehabilitation mat body 1 is provided, and acupressure balls 2 are provided at intervals on the top of the rehabilitation mat body 1. A pressure sensor 3 with an external power supply is provided inside the acupressure ball 2. The pressure sensor 3 adopts a micro-thin film pressure sensor 3. When the patient steps on the rehabilitation mat body 1 with weight, the top of the acupressure ball 2 is smooth, which can avoid pricking the skin on the one hand, and can effectively stimulate the acupuncture points and reflex areas on the sole of the foot.

[0036] Moreover, the detection end of the pressure sensor 3 is exposed to the top surface of the acupressure ball 2. When the patient steps on the acupressure ball 2, the pressure sensor 3 can directly sense the pressure exerted on the sole of the foot. All pressure sensors 3 are connected to the bus inside the rehabilitation mat body 1 through built-in wires, and finally collected into the data processing unit, and finally form a real-time sole pressure distribution map, which helps patients to make timely adjustments, improves the patient's postoperative rehabilitation training effect, and avoids injuries caused by incorrect posture.

[0037] It should be further explained that the rehabilitation pad body 1 is made of high-density environmentally friendly EVA foam material, which provides good cushioning, resilience and pedaling comfort, while ensuring sufficient support force. In addition, the rehabilitation pad body 1 is designed to be flexible to help fit the contour of the sole of the foot, so that the pressure sensor 3 can obtain more realistic readings.

[0038] In this embodiment, the rehabilitation mat body 1 is made of a flexible material, and three areas are formed on the rehabilitation mat body 1: a precision control training area 101, a stable transition area 102 and a functional recovery area 103. There is an area line 5 engraved on the top of the rehabilitation mat body 1 between each area, and the stable transition area 102 is located between the precision control training area 101 and the functional recovery area 103.

[0039] It should be noted that by setting three areas, namely the precision control training area 101, the stable transition area 102 and the functional recovery area 103, on the rehabilitation mat body 1, the area of each area is the same, and there is an area line 5 clearly engraved on the top of the rehabilitation mat body 1 between the three areas, so that the user can easily identify and locate each area.

[0040] In this embodiment, the acupressure ball 2 is made of silicone material, the vertical cross-sectional profile of the acupressure ball 2 is a hemisphere, the acupressure ball 2 is fixedly connected to the rehabilitation mat 1 and distributed in an array, and the number of the acupressure balls 2 arranged gradually decreases from the precision control training area 101 toward the functional recovery area 103.

[0041] It should be noted that the acupressure ball 2 is made of silicone material with good biocompatibility and moderate texture. Its vertical cross-section is a hemispherical shape with a smooth top to avoid puncturing the skin, while effectively stimulating the acupuncture points and reflex areas on the soles of the feet.

[0042] The number of acupressure balls 2 arranged gradually decreases from the precision control training area 101 toward the functional recovery area 103. Specifically, the number of pressure sensors 3 distributed in the precision control training area 101 is the densest, providing more accurate pressure distribution to the feet when the patient just starts weight-bearing training, thereby being used for accurate weight-bearing control in the early postoperative period and preventing excessive weight-bearing in the early bone healing period.

[0043] When the patient enters the mid-term balance training after a period of rehabilitation, rehabilitation training can be performed in the stable transition zone 102. At this time, the patient's excessive weight bearing is reduced, and reducing the number of pressure sensors 3 can guide the patient to independently control the weight bearing ratio.

[0044] During the later stage of rehabilitation training, the number of pressure sensors 3 in the functional recovery area 103 is the least, which is used for the later stage of full weight-bearing adaptation, thereby eliminating the patient's dependence on external equipment and reconstructing a natural gait.

[0045] Through the setting of the above-mentioned multiple areas, patients can choose different areas for rehabilitation according to their own conditions, but are not limited to rehabilitation in the above-mentioned one area. During rehabilitation training, patients can also gradually move from the precision training area 101 to the functional recovery area 103. This gradient distribution is more in line with rehabilitation needs and further improves the rehabilitation effect for orthopedic patients.

[0046] In this embodiment, a detachably connected cleaning pad body 6 is provided on the top of the rehabilitation mat body 1. There are three cleaning pad bodies 6, which are respectively located on the top of the precision control training area 101, the stable transition area 102 and the functional recovery area 103. The bottom of the cleaning pad body 6 and near the edges are provided with spaced-apart hook stickers 7. The top of the rehabilitation mat body 1 is provided with a fleece sticker 8 opposite to the hook sticker 7. The hook sticker 7 and the fleece sticker 8 are adhered to each other.

[0047] It should be noted that the cleaning pad 6 is made of antibacterial cloth material that is easy to clean and disinfect. It passes through the acupressure ball 2 and the anti-slip ridges 10, so that the user can directly contact the cleaning pad 6, which improves the hygiene and safety of the product and will not significantly affect the touch of the acupressure ball 2 and the sensitivity of the pressure sensor 3.

[0048] When the user performs weight training on the rehabilitation mat body 1 , for example, the sweat flowing will also drip directly onto the cleaning mat body 6 , avoiding dripping onto the rehabilitation mat body 1 .

[0049] The number of them is designed to be three, covering the top of the precision training area 101, the stable transition area 102 and the functional recovery area 103 respectively. With this partitioned covering design, when the patient trains only in a certain area, after the training is completed, only the cleaning pad 6 on the trained area can be removed for cleaning, which is convenient for separate cleaning and replacement without affecting the use of other areas.

[0050] At the bottom of the cleaning pad body 6, near the edges, there are spaced apart hook stickers 7, and at the top of the rehabilitation pad body 1, there is a fleece sticker 8 precisely positioned opposite to the hook sticker 7. The hook sticker 7 and the fleece sticker 8 adhere to each other to achieve a firm and detachable connection between the cleaning pad body 6 and the rehabilitation pad body 1. When disassembling, you only need to gently lift a corner of the cleaning pad body 6, which is simple and convenient.

[0051] In this embodiment, each of the rehabilitation pad bodies 1 is provided with through holes 9 distributed in an array, and the positions of the through holes 9 cooperate with the acupressure balls 2. The top of the cleaning pad body 6 is provided with anti-slip ridges 10 distributed at intervals. The anti-slip ridges 10 are made of silicone material. The cross-sectional profile of the anti-slip ridge 10 is "X"-shaped and is located between two adjacent acupressure balls 2.

[0052] It should be noted that by arranging anti-slip ridges 10 on the top of the cleaning pad body 6, which are also made of silicone material, multi-directional anti-slip friction can be provided, effectively preventing the user from slipping when standing or performing training movements. Its cross-sectional profile is designed to be "X"-shaped. The "X"-shaped cross structure has good elasticity and support, can share part of the pressure on the sole of the foot, and increase the comfort of stepping.

[0053] In this embodiment, the top of the rehabilitation mat 1 is provided with alarms 11 distributed at intervals. There are three alarms 11, which are respectively located in the precision control training area 101, the stable transition area 102 and the functional recovery area 103. Text identification areas 12 are provided on both sides of the precision control training area 101, the stable transition area 102 and the functional recovery area 103.

[0054] It should be noted that an alarm 11 is set on the top of the rehabilitation mat 1. There are three alarms 11, which are respectively located in the precision training area 101, the stable transition area 102 and the functional recovery area 103. The specific position of the alarm 11 is not limited here, as long as it does not get in the way.

[0055] The alarm 11 uses an LED indicator light and a buzzer to alarm. The alarm 11 is connected to a data processing unit. The alarm 11 triggers a corresponding alarm based on a preset pressure threshold or training target (for example: insufficient pressure in a certain area, uneven pressure distribution, excessive weight on one side, exceeding the safe load, etc.), and immediately reminds the user to adjust the posture, force method or stop training to prevent secondary injuries caused by incorrect training, and guide the user to complete the training movements correctly.

[0056] Text marking areas 12 are provided on both sides of the precision control training area 101 , the stable transition area 102 and the functional recovery area 103 , which can further enhance the intuitiveness of use.

[0057] In this embodiment, a fixedly connected protection pad 13 is provided at the bottom of the rehabilitation pad 1. The protection pad 13 is made of the same material as the rehabilitation pad 1. The bottom of the protection pad 13 is provided with anti-slip stripes 14 distributed at intervals.

[0058] It should be noted that the protective pad body 13 can be integrally connected to the rehabilitation mat body 1 by gluing or hot melting. By arranging the protective pad body 13 at the bottom of the rehabilitation mat body 1, the bottom of the rehabilitation mat body 1 can be protected from wear and impact, and the thickness and stability of the entire floor mat can be increased.

[0059] The bottom of the protective pad body 13 is provided with anti-slip stripes 14 distributed at intervals, which can enhance the friction between the floor mat and the ground, prevent the floor mat from shifting during use, and ensure the safety of patients during weight-bearing rehabilitation training.

[0060] In this embodiment, the vertical cross-sectional profile of the load-bearing frame 4 is "concave", and a bearing groove 15 is provided on the top of the load-bearing frame 4. The height of the bearing groove 15 is less than the height of the rehabilitation pad 1 and the protection pad 13. The blood circulation component includes a heating element 16, a thermal insulation element 17, an electric wire 18 and a plug 19. The thermal insulation element 17 is located on the inner bottom end of the load-bearing frame 4, and the heating element 16 is located on the top of the thermal insulation element 17. The heating element 16 adopts a graphene heating method. One end of the electric wire 18 is connected to the heating element 16, and the other end extends out of the load-bearing frame 4. The plug 19 is fixedly connected to the other end of the electric wire 18.

[0061] It should be noted that the load-bearing frame 4 is made of engineering plastic, which can ensure that the overall structure is stable and can bear the weight of the human body. A load-bearing groove 15 is provided on the top of the load-bearing frame 4, and the load-bearing groove 15 is used to accommodate and support the rehabilitation pad 1 above.

[0062] The height of the bearing groove 15 is designed to be smaller than the total height of the rehabilitation pad 1 and the protection pad 13 after being superimposed. This means that when the rehabilitation pad 1 + protection pad 13 combination is placed in the bearing groove 15, the upper surface of the combination (i.e., the surface where the acupressure ball 2 is located) will be slightly higher than the edge of the load-bearing frame 4, ensuring that the user's feet only touch part of the rehabilitation pad 1 when stepping on it, and will not step on the edge of the load-bearing frame 4 to cause discomfort. Moreover, the load-bearing frame 4 and the rehabilitation pad 1 are detachably connected and fixed. No specific limitation is made here on the connection method. The blood circulation component is installed in the load-bearing frame 4. When the foot does not need to be heated and blood circulation is activated, it can be quickly disassembled to separate the two, which is also convenient for assembling and maintaining the internal components in the later stage.

[0063] It should be further explained that the thermal insulation member 17 is located on the inner bottom end of the load-bearing frame 4. The thermal insulation member 17 is made of a high-temperature resistant, low-thermal conductivity material. When the heating member 16 is heating, the thermal insulation member 17 can prevent the heat generated by the heating member 16 from being transferred downward to the ground or the bottom of the load-bearing frame 4, preventing overheating from damaging the ground or the frame, and at the same time reflecting the heat into the rehabilitation mat body 1 above.

[0064] The heating element 16 can emit heat after being powered on. The heat penetrates the protective pad body 13 and the rehabilitation pad body 1 upwards and is finally transferred to the sole of the user's foot. The mild heat therapy can effectively expand the capillaries in the sole of the foot, promote blood circulation, relieve muscle tension, stiffness and pain, and enhance the rehabilitation effect.

[0065] Among them, the heating element 16 adopts a graphene heating film. Graphene has significant advantages such as high electrothermal conversion efficiency, uniform heating, rapid temperature rise, good flexibility, safety and reliability, and long life.

[0066] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
