Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, specifically to a rehabilitation device for simultaneous hand and foot training for diabetic patients. Background Technology

[0002] Diabetic peripheral neuropathy is one of the most common chronic complications of diabetes, with distal symmetrical polyneuropathy being the most common type. The neuropathy in both upper and lower extremities originates from the same metabolic pathological process—oxidative stress induced by hyperglycemia, mitochondrial dysfunction, and axonal degeneration—resulting in homologous, synchronous, and symmetrical nerve damage in the hand and foot extremities. Its core clinical feature is symmetrical sensory disturbance in the extremities, specifically numbness, tingling, burning, or crawling sensations simultaneously in the hands and feet.

[0003] Therefore, in a single massage movement in the field of rehabilitation therapy, the extremities of the hands and feet simultaneously receive stimulation input with the same rhythm and timing. This helps the brain process these two signals with a unified neural representation, thereby producing a synergistic and enhanced therapeutic effect and promoting the recovery of the extremities.

[0004] However, existing diabetic hand-foot synchronization devices generally employ a separate, active training method. Patients typically use hand-grip devices (such as hand grip strengtheners) to perform hand movements while simultaneously relying on foot-pedal devices (such as foot massage pads) for foot trotting or massage.

[0005] In actual use, this type of separate and active rehabilitation device requires the patient to control it with their own consciousness. However, most patients with diabetic peripheral neuropathy are elderly and often have characteristics such as decreased muscle strength and dulled senses. This training method separates the hand training movements from the foot training movements in time and space, which easily leads to poor synchronization of hand and foot training and poor recovery effect. Summary of the Invention

[0006] The purpose of this invention is to provide a rehabilitation device for simultaneous hand and foot training for diabetic patients, so as to solve the technical problem of poor synchronization of hand and foot training caused by the separate setting of training devices and the need for active operation by patients in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A rehabilitation device for synchronized hand and foot training for diabetic patients includes a mounting bracket. The upper layer of the mounting bracket is provided with a finger opening and closing training component, and the lower layer of the mounting bracket is provided with a foot pressing training component. The finger opening and closing training component and the foot pressing training component are connected by a transmission structure for synchronized training. Specifically: The finger opening and closing training component includes a base plate, multiple sliding plates, traction cables, and a first rotating shaft. The base plate is fixedly mounted on the mounting bracket. The multiple sliding plates are arranged radially on the base plate, and each sliding plate is slidably mounted on the base plate and slides back and forth along its own length. The sliding plates are provided with fixing members for fixing the fingers. Each sliding plate is connected to a traction cable, and each traction cable is wound at a different position on the first rotating shaft. The traction direction of the traction cable is the same as the sliding direction of the sliding plate. The first rotating shaft is connected to the transmission structure so that when it rotates axially, the traction cables drive the sliding plates to slide and train the fingers to open and close. The foot massage training component includes an open shell, a flexible substrate, a pressing plate, and a second rotating shaft. The open shell is fixedly disposed on the lower layer of the mounting bracket, and the flexible substrate is fixedly disposed on the opening of the open shell facing the patient. The flexible substrate is used to support the sole of the foot. The second rotating shaft is rotatably disposed within the open shell and connected to the transmission structure for axial rotation. The pressing plate is fixedly disposed on the second rotating shaft and disposed within the open shell. The second rotating shaft, through axial rotation, drives the pressing plate to massage the sole of the foot by periodically pressing against the flexible substrate.

[0008] Furthermore, the transmission structure includes a drive source and a belt assembly. The output end of the drive source is fixedly connected to the end of the second rotating shaft, the other end of the second rotating shaft is connected to the belt assembly, and the other end of the belt assembly is connected to the end of the first rotating shaft.

[0009] Furthermore, the substrate has multiple sliding grooves, each of the slide plates is slidably disposed in the corresponding sliding groove, and a return spring is fixedly disposed in the sliding groove. The return spring extends and retracts along the length of the sliding groove, and the end of the return spring is fixedly connected to the slide plate.

[0010] Furthermore, a groove is formed on the slide plate, and a pull plate is rotatably disposed in the groove. The fixing member is disposed on the pull plate. One end of the pull plate is rotatably disposed in the groove, and the other end is a free end connected to the pull cable. The free end of the pull plate rotates and opens and closes around the rotating end of the pull plate under the traction of the pull cable. A first roller is rotatably mounted above the traction plate via a reset torsion spring. The traction cable is wrapped around the first roller and extends vertically downward to connect with the free end of the traction plate.

[0011] Furthermore, the first rotating shaft is rotatably disposed on one side of the slide plate, and a plurality of second rollers are linearly arrayed on the first rotating shaft. The second rollers are coaxially fixedly disposed on the first rotating shaft, and the other end of the traction cable is connected to the second rollers. A guide mounting block is provided on the base plate, and the extension direction of the traction cable is adjusted by the guide mounting block so that the traction direction of the traction cable is collinear with the sliding direction of the slide plate.

[0012] Furthermore, a flexible block is provided on the substrate to support the patient's wrist. The flexible block is slidably disposed on the substrate and is connected to a second roller disposed on the first rotating shaft via the traction cable.

[0013] Furthermore, the second rotating shaft is linked to a third rotating shaft via a gear structure. The third rotating shaft is provided with a pressure plate. When rotating, the pressure plate intermittently presses against the flexible substrate to act on the sole of the foot, and the pressure plate and the pressing plate contact the sole of the foot in an alternating pressing manner.

[0014] Furthermore, a door is rotatably provided on the open shell, and a medicated bath spray head is provided above the open shell. The medicated bath spray head is connected to an external medicine tank through a pump assembly to spray medicine onto the feet.

[0015] Furthermore, the bottom of the open shell is provided with a waste liquid chamber, and the surface of the waste liquid chamber is provided with a drain outlet for receiving the medicine liquid after spraying the feet. The waste liquid chamber is connected to a drain pipe and connected to an external waste liquid collection box.

[0016] Compared with the prior art, the present invention has the following advantages: In this invention, foot massage is achieved by rotating a first shaft to open and close the fingers and rotating a second shaft to press the sole of the foot. A transmission structure connects the first and second shafts, and a single drive source synchronously drives both training components to operate in coordination. This highly synchronizes the two training movements, eliminating rhythmic deviations and movement separations caused by asynchronous operation, resulting in higher synchronization performance and better recovery effects. Furthermore, both the first and second shafts drive local small joint training movements (finger opening and closing and foot pressing), targeting the extremities most commonly affected by diabetic peripheral neuropathy, making the training more targeted and particularly suitable for passive use by elderly diabetic patients with decreased muscle strength and sensory impairment.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 and Figure 8 As shown, this application provides a hand-foot synchronous training and rehabilitation device for diabetic patients. A mounting bracket 7 is provided, with a finger opening and closing training component on the upper layer and a foot pressing training component on the lower layer. The finger opening and closing training component and the foot pressing training component are connected by a transmission structure 10 for synchronous training. Specifically: The finger opening and closing training component includes a base plate 1, such as Figure 1 As shown, substrate 1 can be disposed inside an outer casing, and the outer casing covers substrate 1 to form a closed space. The outer casing can be configured as two corresponding hands, such as... Figure 1 As shown, the outer casing can be equipped with a hinged door with openings for hand access. The base plate 1 can be a generally flat shell structure, on which multiple sliding plates 2 are mounted. To simulate the radial arrangement of fingers when the human hand is naturally extended, adjacent sliding plates 2 are angled together. The interior of the base plate 1 has five grooves 17 corresponding to the natural extension directions of the five fingers, with a sliding plate 2 slidably connected to each groove 17. With this configuration, the five sliding plates 2 correspond to the thumb, index finger, middle finger, ring finger, and little finger, respectively.

[0022] like Figure 1 As shown, the slide plate 2 is slidably disposed within the slide groove 17. Each slide plate 2 is provided with a fixing element 3 for stably fixing the patient's fingers on the slide plate 2. The fixing element 3 may include a fixing ring and a fixing strap provided on the traction plate 20, such as... Figure 1 , Figure 5 , Figure 6 As shown, after the patient passes their finger through the fixation ring, the finger is then secured by a fixation strap (which can be tightened by wrapping or using Velcro). This structure is simple and reliable, ensuring that the finger will not fall off during subsequent gliding exercises, thus guaranteeing the stability and safety of the training.

[0023] like Figure 1 , Figure 5 , Figure 6As shown, to achieve passive finger opening and closing exercises, each skateboard 2 is connected to a pull cable 4. These pull cables 4 are used to pull their respective skateboards 2 along their length direction (i.e., the direction of the groove 17). Crucially, all pull cables 4 are wound at different positions on the same first pivot 5, such as... Figure 2 As shown.

[0024] like Figure 2 As shown, a plurality of second rollers 22 are coaxially arranged on the first rotating shaft 5, and the position of each second roller 22 corresponds to each slide groove 17. One end of each pull cable 4 is fixedly connected to the corresponding second roller 22, and the other end is connected to the corresponding slide plate 2. With this arrangement, when the first rotating shaft 5 rotates, each second roller 22 will synchronously wind up its corresponding pull cable 4, and because the winding positions are different, the stroke of each pull cable 4 is independently controllable, thus enabling synchronous but non-interfering traction of each slide plate 2.

[0025] In addition, to ensure that the direction of the traction force is consistent with the sliding direction of the slide plate 2, and to improve transmission efficiency and structural stability, a guide mounting block 23 is also provided on the base plate 1, such as... Figure 1 As shown, the traction cable 4 passes through the guide mounting block 23, so that its traction direction is collinear with the sliding direction of the slide plate 2.

[0026] With the above structure, when the device is working, the drive source 11 drives the first rotating shaft 5 to rotate in the forward direction, winding and tightening the pull cable 4. The pull cable 4 applies a pulling force to the slide plate 2 in the direction of the first rotating shaft 5, thereby overcoming the resistance of the spring and pulling the slide plate 2 and the fingers fixed on it to slide outward along the slide groove 17.

[0027] Because the slides 17 are arranged radially, the outward sliding of the slide plate 2 increases the distance between adjacent slide plates 2, thereby passively opening the patient's five fingers outward, achieving "opening" training. When the first rotating shaft 5 rotates in the opposite direction, the traction cable 4 loosens, and the slide plate 2 slides inward along the slide groove 17 under the action of the return spring 18, causing the fingers to close, achieving "closing" training. Through the reciprocating rotation of the drive source 11, continuous, stable, and safe passive opening and closing exercises for the patient's fingers can be achieved.

[0028] In a more preferred embodiment, to further enhance the training effect and simulate the fine motor skills of finger flexion and extension, the structure of the skateboard 2 has been optimized. Please refer to [reference needed]. Figure 6 and Figure 7A groove 19 is formed on the skateboard 2, and a pull plate 20 is rotatably mounted within the groove 19. The aforementioned fixing components 3 (fixing ring and fixing strap) are mounted on the pull plate 20. One end of the pull plate 20 is rotatably mounted at the end of the groove 19 via a pivot, and the other end is a free end used to connect to the pull cable 4. Under the traction of the pull cable 4, the free end of the pull plate 20 can rotate upwards and downwards around its rotating end, thereby enabling upward lifting training of the fingers fixed to the fixing component 3.

[0029] At this time, one end of the traction cable 4 is connected to the free end of the traction plate 20. To optimize the transmission of the movement, a first roller 21 is rotatably mounted above the traction plate 20 via a return torsion spring. The traction cable 4 is wrapped around the first roller 21 and extends vertically downward to connect with the free end of the traction plate 20. Thus, when the traction cable 4 is wound up, since the traction cable 4 is connected to the first rotating shaft 5, which is located in front of the traction plate 20, the force exerted by the traction cable 4 on the traction plate 20 is decomposed into two components, one vertically upward and the other horizontally forward. The vertically upward force applied to the traction plate 20 pulls the free end of the traction plate 20 upward through the first roller 21, causing the traction plate 20 to lift upward, thus exercising the finger joints. The horizontally forward force drives the traction plate 20 to slide within the groove 17 along the direction of the traction cable 4, thereby enabling finger opening and closing. Similarly, when the first rotating shaft 5 reverses, the traction cable 4 loosens, and the traction plate 20 descends back into the groove 19 under the action of the return torsion spring, realizing the downward exercise of the fingers; the slide plate 2 returns to its original position under the traction of the return spring 18, realizing the closure of the fingers. In this way, this device completes both finger opening and closing training and finger upward and downward training in the same driving cycle, realizing multi-degree-of-freedom local joint coordinated exercise that is closer to the physiological activity law.

[0030] like Figure 1 As shown, in a preferred embodiment, to further improve patient comfort and device airtightness during training, a flexible block 24 is provided on the base plate 1 to support the patient's wrist. This flexible block 24 can be a sponge pad or other elastic material. Furthermore, the flexible block 24 is not fixed but slidably mounted on the base plate 1, and it is also connected to a second roller 22 mounted on the first rotating shaft 5 via an independent traction cable 4. When the first rotating shaft 5 rotates, the flexible block 24 is pulled and slowly moves back and forth, tractioning and pushing the patient's wrist area. Its main purpose is to move the entire hand by tractioning the wrist, thereby avoiding insufficient traction force when driving the fingers alone, and preventing strain on local finger areas. The traction cable 4 connecting the flexible block 24 can be located inside the base plate 1, extending outwards to connect to the second roller 22 of the first rotating shaft 5, as shown below. Figure 2 As shown.

[0031] At the same time, refer to Figure 3 , Figure 4 and Figure 8 To enable foot muscle training, the device also includes a flexible substrate 6, which is connected to the substrate 1 via a mounting bracket 7 and positioned below the substrate 1, forming an integrated training platform to allow a single person to perform simultaneous hand and foot training. Figure 4 As shown, an outer shell is fitted over the substrate 1 to form a hand exercise assembly 35 on the upper layer of the mounting bracket 7, and an open shell 28 is provided on the flexible substrate 6 to form a foot exercise assembly 36 on the lower layer of the mounting bracket 7, forming an integrated device capable of providing simultaneous hand and foot training for a single person. Specifically, the mounting bracket 7 includes a support connecting the hand exercise assembly 35 and the foot exercise assembly 36, as well as other components that support the patient's body (e.g., Figure 4 The design of the mounting bracket 7 for the extension plate at the front of the midfoot exercise assembly is varied in the prior art. The attached figure shows only one embodiment, which can be configured to accommodate other structures for patients sitting, lying down, or with joint flexion. For example, a seat cushion 37 can be provided at the front of the foot exercise assembly for patients to use in a sitting position.

[0032] Specifically, such as Figure 3 As shown, the flexible substrate 6 is an elastically deformable flexible sheet fixedly mounted on the open housing 27. A pressing plate 9 is rotatably mounted inside the open housing 27, and the pressing plate 9 is fixedly mounted on the second rotating shaft 16. The second rotating shaft 16 rotates axially to drive the pressing plate 9 to periodically press against the flexible substrate 6, thus massaging the sole of the foot. During operation, when the second rotating shaft 16 rotates around its own axis, it drives the pressing plate 9 to rotate accordingly. Its working end periodically presses against the inner surface of the flexible substrate 6 during rotation, causing the flexible substrate 6 to periodically protrude outwards. Since the patient's foot is placed on the outer side of the flexible substrate 6, this periodic protrusion is transmitted to the sole of the foot, thus providing a dynamic massage effect. Furthermore, a top post can be provided on the surface of the flexible substrate 6. Placing the patient's foot on the top post creates a gap between the foot and the flexible substrate 6, resulting in better drug spraying.

[0033] With this structure, when the second rotating shaft 16 rotates around its own axis, it will cause the pressing plate 9 on it to rotate accordingly. Since the pressing plate 9 has an eccentric or non-circular structure, it will intermittently press against the flexible substrate 6 when it rotates, thereby creating a regular pressing stimulation on the patient's sole placed on it.

[0034] This type of pressure can effectively activate the deep intrinsic muscle groups, nerve endings and capillaries of the sole of the foot, which plays an important role in improving foot sensation, promoting local blood circulation, and preventing foot arch collapse and foot muscle atrophy in diabetic patients.

[0035] like Figure 5 As shown, the transmission structure 10 includes a drive source 11 (e.g., a servo motor) and a belt assembly 12 connected to the output end of the drive source 11. The output end of the belt assembly 12 is connected to the ends of a first rotating shaft 5 (for hand training) and a second rotating shaft 16 (for foot training), respectively, thereby transmitting the power of the drive source 11 to both the hand and foot modules simultaneously.

[0036] In a preferred embodiment of a specific power transmission path, the output end of the drive source 11 is fixedly connected to the end of the second rotating shaft 16, directly driving the second rotating shaft 16 to rotate. By directly connecting to the second rotating shaft 16, the drive source 11 can drive the second rotating shaft 16, which has greater resistance, thus making more efficient use of the power of the drive source 11. The other end of the second rotating shaft 16 is connected to a belt assembly 12, which is a belt transmission assembly. Specifically, it may include: a first transmission belt 13, a redirecting column 14, and a second transmission belt 15. One end of the first transmission belt 13 is connected to the second rotating shaft 16, and the other end is connected to the redirecting column 14. One end of the second transmission belt 15 is connected to the redirecting column 14, and the other end is connected to the end of the first rotating shaft 16, so that the two rotating shafts can be driven to rotate synchronously by a single drive source 11.

[0037] To enhance the stimulation effect on the soles of the feet and make it more closely resemble the alternating pressure sensation during walking, the foot massage module of this device has been further optimized. In a preferred embodiment, such as... Figure 8 As shown, the second rotating shaft 16 is linked to the third rotating shaft 25 via a set of gears. The third rotating shaft 25 also has at least one pressure plate 26. The pressure plate 26 intermittently presses against the flexible substrate 6 during rotation, acting on the sole of the foot. Crucially, the pressure plate 26 and the aforementioned pressing plate 9 are arranged alternately in space and time. That is, when the second rotating shaft 16 causes the pressing plate 9 to protrude and press a certain area of ​​the sole, the pressure plate 26 on the third rotating shaft 25 is in a retracted state; when the second rotating shaft 16 continues to rotate, the pressing plate 9 retracts, and the pressure plate 26 protrudes and presses another area of ​​the sole. This repeated action creates an alternating pressing effect, which can more precisely simulate the dynamic distribution of foot pressure changes during walking, thereby providing more comprehensive stimulation and training to the foot reflex zones and muscle groups.

[0038] In addition, this device takes into account the physiological characteristics and rehabilitation needs of diabetic patients, especially those at risk of diabetic foot. Compared to the general population, diabetic patients often experience reduced sensation, microcirculatory disturbances, and involuntary muscle atrophy in the extremities. Excessive active exertion or large-scale joint movements can lead to injury that is difficult to detect.

[0039] Therefore, this device utilizes low active load and high rhythmic stimulation. First, the hand training module, through the coordination of the first rotating shaft 5 and the traction cable 4, applies a smooth and controllable passive traction force to the patient's fingers, rather than requiring the patient to actively grasp or push / pull, thus avoiding muscle or ligament strains caused by inaccurate force perception. Second, the radial arrangement of multiple sliding plates 2 at an angle precisely simulates the physiological trajectory of natural finger extension, ensuring that each opening and closing exercise accurately targets the finger joints and intrinsic hand muscles such as the lumbrical muscles. This is crucial for delaying claw hand deformity in diabetic patients and maintaining finger opposition function.

[0040] In terms of foot training, the alternating pressure design of the plantar pressure plate 9 and the staggered pressure plate 26 is specifically designed for diabetic patients with loss of foot sensation and collapsed arches. This dynamic, alternating rhythmic stimulation can continuously activate the plantar intrinsic muscle groups and proprioceptive receptors without relying on the patient's voluntary activities, simulating the natural pattern of foot pressure center shifting during walking.

[0041] This not only helps rebuild the sensory feedback loop between the brain and the sole of the foot, improving gait balance, but more importantly, the regular mechanical pressure promotes local microcirculation and blood flow, effectively relieving foot edema and tissue hypoxia caused by neuropathy, and has direct clinical value in preventing diabetic foot ulcers. Furthermore, the integrated medicated bath spray system can combine physical pressure with antibacterial or blood-activating medications for adjuvant treatment, forming a synergistic physical-chemical rehabilitation program, further reducing the risk of foot infection and necrosis in diabetic patients.

[0042] Example 2 like Figure 3 As shown, in a further optimized embodiment, to combine pharmacology and physical therapy for better treatment of diabetic foot, the flexible substrate 6 is fixedly disposed inside the opening housing 27. The opening housing 27 provides a relatively sealed treatment space, preventing medication splashing and heat loss.

[0043] A door 28 is rotatably mounted on the open housing 27, and a foot bayonet is provided on the door 28 to accommodate the patient's lower leg. To maintain a seal, a flexible sealing ring can be provided at the foot bayonet.

[0044] In addition, a medicated bath spray head 29 is provided on the upper part of the open housing 27 (e.g., on the inner top wall or upper side). This medicated bath spray head 29 is connected to an external medicine tank 31 via a pump assembly 30. When the device is in operation, the pump assembly 30 can be activated as needed to draw therapeutic solutions (such as antibacterial solutions, traditional Chinese medicine washes for promoting blood circulation and removing blood stasis) from the external medicine tank 31 and deliver them to the medicated bath spray head 29, spraying them onto the patient's feet in a mist or jet form. Simultaneous medicated bath spraying with foot massage exercises provides a comprehensive therapeutic effect, including cleaning the wound, reducing inflammation and bacteria, promoting drug absorption, and enhancing local metabolism.

[0045] To ensure proper collection of the sprayed medication and prevent environmental pollution, a waste liquid chamber 32 is provided at the bottom of the open housing 27. The surface of this waste liquid chamber 32 has a drain outlet 33 to collect the medication flowing down after spraying the feet. The waste liquid chamber 32 itself functions to collect and temporarily store waste liquid, and a drain pipe 34 is connected to its lowest point. This drain pipe 34 can be further connected to an external waste liquid collection tank, thereby achieving centralized and closed-loop discharge of waste liquid. This design greatly simplifies post-treatment cleanup and reduces the risk of cross-infection due to medication leakage.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. All such modifications or substitutions should be covered within the protection scope of this application, and should not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
