Abstract

This invention discloses an integrated massage device for lower limbs and foot acupoints for long-term bedridden patients, relating to the fields of medical care equipment and rehabilitation technology. It addresses the problem that existing foot massage devices for bedridden patients primarily offer rotational massage, only achieving mechanical rotational movement and failing to simulate the movements of traditional Chinese massage, resulting in insufficient stimulation of foot acupoints. The device comprises a foot-limiting platform fixed to the upper middle of a supporting base, with an external foot wrapping component fixed to the front end of the platform. Foot acupoint units are connected to the front and rear ends of the foot-limiting platform. Each acupoint unit includes two foot support plates fixed to both sides of the front end of the foot-limiting platform. A flexible footrest is attached to the front end of each support plate, with a foot positioning groove formed in the middle of the front surface of the flexible footrest. Multiple hemispherical massage elements are disposed within this groove, allowing for alternating up-and-down movement.

Description

Technical Field

[0001] This invention relates to the field of medical care equipment and rehabilitation technology, specifically to an integrated massage device for lower limbs and foot acupoints for long-term bedridden patients. Background Technology

[0002] Long-term bedridden patients refer to those who need to remain in bed for weeks or even months due to illness, trauma, post-operative recovery, or other reasons. Approximately 70% of newly diagnosed stroke patients each year have varying degrees of limb dysfunction and require long-term bed rest. In addition, patients with spinal cord injuries, those recovering from severe fractures, those with severe traumatic brain injury, and those with advanced cancer also constitute a major group of long-term bedridden patients.

[0003] Patients who are bedridden for a long time are prone to problems such as: impaired venous return in the lower extremities, foot edema, muscle atrophy, stiffness of the soles of the feet, deep vein thrombosis, and pressure sores due to limited mobility.

[0004] Common nursing methods often rely on manual massage by caregivers, but these methods suffer from problems such as high workload, inconsistent massage intensity, poor continuity, and inability to accurately stimulate acupoints on the soles of the feet. Foot massage equipment for bedridden patients primarily features rotary massage, which only achieves mechanical rotation and cannot simulate the movements of traditional Chinese massage, resulting in insufficient stimulation of acupoints on the soles of the feet. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated massage device for lower limbs and foot acupoints for long-term bedridden patients, in order to solve the problem in the background art that foot therapy devices for bedridden patients mainly have a rotational massage function, which can only realize the mechanical movement of rotation and cannot simulate the movements in traditional Chinese massage, resulting in insufficient stimulation of acupoints on the soles of the feet.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated massage device for lower limbs and foot acupoints for long-term bedridden patients, comprising a lower limb support unit, the lower limb support unit including a support base and a rear baffle fixed to the upper rear end of the support base, a foot limiting platform fixed in the middle of the upper end of the support base, a foot outer wrapping component fixed to the front end of the foot limiting platform, and a foot acupoint unit connected to the front and rear ends of the foot limiting platform, the foot acupoint unit including two foot support plates fixed to both sides of the front end of the foot limiting platform, the foot... A flexible footrest is attached to the front end of the support plate. A foot positioning groove is formed in the middle of the front surface of the flexible footrest. Multiple hemispherical massage elements are arranged in the foot positioning groove. The hemispherical massage elements can move up and down alternately. The foot acupoint unit also includes two vertical action plates. The vertical action plates are located at the rear end of the foot support plate. Multiple fixing sleeves are fixed to the front end of the vertical action plates. The number of fixing sleeves is the same as the number of hemispherical massage elements and their front and rear positions correspond. The rotation axis of the hemispherical massage elements passes through the flexible footrest, the foot support plate, the foot limiting platform and the fixing sleeves and extends backward.

[0007] Preferably, the flexible footrest, foot support plate, and foot limiting platform are all provided with vertical adjustment grooves along the vertical movement trajectory of the hemispherical massage component's rotation axis; the foot acupoint unit also includes two vertical drive threaded rods, which are located on the outer side of the rear end of the foot support plate. The upper and lower ends of the outer side of the vertical drive threaded rods are connected to threaded sleeves by threads, and the front end of the threaded sleeves is fixed with a first connecting rod. Each group of two first connecting rods is fixed to the upper and lower ends of the outer side of the rear end of the vertical action plate; the foot acupoint unit also includes a first drive motor installed at the front end of the rear baffle. The output shaft end of the first drive motor is equipped with a first bevel gear, and the inner side of the first bevel gear is meshed with a second bevel gear, which is installed in the middle of the outer side of the vertical drive threaded rod.

[0008] Preferably, multiple rear connecting rods are fixed from top to bottom on both sides of the rear end of the vertical action plate. A longitudinal action plate is slidably connected to the outside of two rear connecting rods in each row. The longitudinal action plate has an inverted "convex" structure. A pressure spring is provided between the longitudinal action plate and the vertical action plate along the outside of the rear connecting rods. A second drive motor is installed at the lower end of the rear end of the vertical action plate between the two rear connecting rods in each row. An eccentric wheel is installed at the output shaft end of the second drive motor, and the outer surface of the eccentric wheel is in contact with the longitudinal action plate. Multiple third drive motors are installed at the rear end of the longitudinal action plate. The third drive motors correspond to the front and rear positions of the hemispherical massage component, and the output shaft end of the third drive motor is connected to the rotation shaft of the hemispherical massage component.

[0009] Preferably, a vertical fixing rod is fixed to the inner side of the vertical drive threaded rod at the front end of the rear baffle by a fixing block. The vertical fixing rod is vertically arranged, and the upper and lower ends of the external side of the vertical fixing rod are slidably connected to limit sleeves. A second connecting rod is fixed to the front end of the limit sleeve. Each group of two second connecting rods is respectively fixed to the upper and lower ends of the inner side of the rear end of the vertical action plate.

[0010] Preferably, mattress side guards are fixed on both sides of the upper end of the support base along the front end of the rear baffle. A mattress base is placed on the upper end of the support base between the two mattress side guards. The mattress base abuts against the front end of the foot limiting platform. The foot outer wrapping piece is located at the rear end of the upper end of the mattress base. Groove channels are opened on both sides of the upper surface of the mattress base.

[0011] Preferably, the groove channel is provided with a knee-lower air pressure massage airbag, a calf-lower air pressure massage airbag and an ankle-lower air pressure massage airbag from front to back, and the knee-lower air pressure massage airbag, calf-lower air pressure massage airbag and ankle-lower air pressure massage airbag are configured with an inflation chamber.

[0012] Preferably, a longitudinal groove is formed in the middle of the front end face of the mattress base, and a fixing bracket is fixed inside the longitudinal groove at the upper end of the support base. Both sides of the upper end of the fixing bracket are fixed with butterfly-shaped fasteners. The knee-lower air pressure massage airbag, the calf air pressure massage airbag, and the ankle air pressure massage airbag are all connected to the mattress base and the butterfly-shaped fasteners.

[0013] Preferably, the air inlet ends of the under-knee air pressure massage airbag, the calf air pressure massage airbag, and the ankle air pressure massage airbag are all equipped with air inlet manifolds, and a first control valve is installed on each air inlet manifold. The other ends of the three air inlet manifolds are connected to a main air inlet manifold through a first connecting member. The air outlet ends of the under-knee air pressure massage airbag, the calf air pressure massage airbag, and the ankle air pressure massage airbag are all equipped with air outlet manifolds, and a second control valve is installed on each air outlet manifold. The other ends of the three air outlet manifolds are connected to a main air outlet manifold through a second connecting member.

[0014] Preferably, a limiting groove is horizontally formed in the middle of both sides of the lower end face of the support base. A limiting slider is limited to slide within the limiting groove. A C-shaped fixing member is fixed at the lower end of the limiting slider. The length of the upper horizontal plate of the C-shaped fixing member is greater than the length of the lower horizontal plate of the C-shaped fixing member. A fixing screw is threadedly connected to the middle position of the lower horizontal plate of the C-shaped fixing member. A fixing horizontal plate is provided inside the C-shaped fixing member along the upper end of the fixing screw. The fixing horizontal plate is rotatably connected to the fixing screw. Vertical rods that slide along the lower horizontal plate of the C-shaped fixing member are provided at both the front and rear ends of the lower end of the fixing horizontal plate.

[0015] Preferably, the lower end of the support substrate is arrayed with a plurality of lower anti-slip particles.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In this invention, under the action of the drive structure, the vertical action plate can move up and down alternately. Since the rotation axis of the hemispherical massage piece is located in the fixed sleeve fixed at the front end of the vertical action plate, the movement of the vertical action plate will drive the hemispherical massage piece to move up and down alternately. The up and down movement of the hemispherical massage piece can imitate the massage techniques of professionals, thereby stimulating more acupoints on the soles of the feet, thus ensuring the massage effect on the feet.

[0018] (2) In this invention, the three massage modes are independently controllable and can be combined arbitrarily, comprehensively covering traditional Chinese massage techniques. The massage mode uses a first drive motor to drive the hemispherical massage piece to move up and down alternately via bevel gear transmission, mimicking the thumb massage technique; the kneading mode uses a third drive motor to drive the hemispherical massage piece to rotate independently, mimicking the thumb kneading technique; the point pressing mode uses a second drive motor to drive an eccentric wheel to achieve rapid back-and-forth alternating movement of the hemispherical massage piece, mimicking the thumb pressing technique. The three modes can be operated individually, any two can be combined, or all three can be operated simultaneously, which can meet the personalized massage needs of different rehabilitation stages and different patients.

[0019] (3) In this invention, the knee-lower air pressure massage airbag, the calf air pressure massage airbag and the ankle air pressure massage airbag are pressurized in sequence in the direction of ankle → calf → knee → ankle... to simulate the manual massage technique of professional nurses from the distal to the proximal end, forming a gradient pressure wave from bottom to top, which effectively promotes the return of deep vein blood in the lower limbs to the heart and reduces the risk of deep vein thrombosis.

[0020] (4) In this invention, the functions of lower limb pneumatic circulation massage, foot massage and multi-mode acupoint massage and rigid bed fixation are integrated into a single device. Patients do not need to switch between multiple devices, which meets the needs of bedridden patients for simultaneous care of "leg circulation + foot acupoint stimulation". The nursing process is greatly simplified. A single operation can simultaneously achieve the dual rehabilitation effect of promoting lower limb venous return and stimulating foot acupoints, thus improving nursing efficiency.

[0021] (5) In this invention, a rigid connection between the device and the bed is achieved by using a C-shaped fixing component in conjunction with a sliding groove guide of a limiting slider and a locking structure where a fixing screw drives the fixing plate to rigidly press against the lower end of the bed. Even when the pneumatic massage generates a large reaction force or the patient's position changes, the device will not shift, ensuring safety and massage stability. Several anti-slip particles arrayed at the lower end of the support base provide additional friction after the device is placed on the bed surface, forming a "rigid + friction" dual fixing guarantee with the rigid locking of the C-shaped fixing component, further eliminating the possibility of displacement.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figures 1-8 This invention provides an embodiment of an integrated massage device for lower limbs and foot acupoints for long-term bedridden patients, comprising a lower limb support unit 1. The lower limb support unit 1 includes a support base 2 and a rear baffle 3 fixed to the upper rear end of the support base 2. A foot limiting platform 25 is fixed to the middle of the upper end of the support base 2, and a foot wrapping component 26 is fixed to the outer front end of the foot limiting platform 25. The foot limiting platform 25 supports the patient's foot and provides a mounting base for the foot acupoint unit 27. The foot wrapping component 26 provides limitation and has a built-in thermotherapy function. Mattress side guards 4 are fixed to both sides of the upper end of the support base 2 along the front end of the rear baffle 3. A mattress base 11 is placed at the front end between the two mattress side guards 4 on the upper end of the support base 2. The mattress side guards 4 form a lateral enclosure structure for the mattress base 11, effectively preventing lateral slippage of the mattress base 11 during use. The mattress base 11 rests against the front end of the foot limiting platform 25, and the foot outer wrapping 26 is located at the rear end of the upper part of the mattress base 11.

[0033] like Figure 1 , Figure 4 and Figure 5As shown, the mattress base 11 serves as the direct support surface for the patient's body, with grooved channels 12 on both sides of its upper surface. The grooved channels 12 provide embedded installation space for the knee-lower air pressure massage airbag 16, the calf-lower air pressure massage airbag 17, and the ankle-lower air pressure massage airbag 18. These airbags are arranged sequentially from front to back, following the natural placement of the patient's legs. When the patient lies flat with their legs naturally extended, the airbags can pass through them in sequence. A longitudinal groove 13 is longitudinally formed in the middle of the front end surface of the mattress base 11, and a fixing bracket 14 is fixed inside the longitudinal groove 13 at the upper end of the support base 2. The fixed bracket 14 serves as an auxiliary fixing structure for the airbag, with butterfly-shaped fixing parts 15 fixed on both sides of its upper end. The knee-lower air pressure massage airbag 16, the calf air pressure massage airbag 17, and the ankle air pressure massage airbag 18 are all connected to the mattress base 11 and the butterfly-shaped fixing parts 15.

[0034] Each of the three air pressure massage airbags—the knee-inflating airbag 16, the calf-inflating airbag 17, and the ankle-inflating airbag 18—is equipped with an inflation chamber 50. The inflation chamber 50 expands when gas is introduced, creating a wrapping pressure on the leg; it contracts and releases the pressure when gas is expelled. Each of the three air pressure massage airbags 16, 17, and 18 has an air inlet manifold 19, on which a first control valve 20 is installed. The first control valve 20 is an electrically controlled valve used to control the airflow to and from the corresponding airbag. The other ends of the three air inlet manifolds 19 are connected to a main air inlet pipe 21 via a first connecting piece. One end of the main air inlet pipe 21 is connected to the outlet of an external inflation / deflation device, which provides a stable air source and pressure control. Each of the three air pressure massage airbags 16 (below the knee), 17 (lower leg), and 18 (ankle), has an air outlet manifold 22 installed at its outlet end. A second control valve 23 is installed on each air outlet manifold 22. The second control valve 23 is an electrically controlled valve used to control the airflow of the corresponding airbag. The other ends of the three air outlet manifolds 22 are connected to a main air outlet pipe 24 via a second connecting piece. One end of the main air outlet pipe 24 is connected to the air inlet of an external inflation / deflation device.

[0035] By controlling the opening and closing combinations of multiple first control valves 20 and second control valves 23, the sequential cyclic inflation and deflation of the three airbags is achieved. The specific working process is as follows:

[0036] In the first stage, the first control valve 20 connected to the ankle air pressure massage airbag 18 is opened, and the other first control valves 20 are closed. Gas enters the inflation chamber 50 of the ankle air pressure massage airbag 18 and is maintained thereafter, simulating the massage and pressure on the foot and ankle area.

[0037] In the second stage, the first control valve 20 connected to the calf air pressure massage airbag 17 is opened, and the other first control valves 20 are closed. Gas enters the inflation chamber 50 of the calf air pressure massage airbag 17 and is maintained thereafter. At the same time, the second control valve 23 connected to the ankle air pressure massage airbag 18 is opened, and the gas in the ankle air pressure massage airbag 18 is quickly discharged, simulating the massage transition from the calf to the ankle.

[0038] In the third stage, the first control valve 20 connected to the knee-lower air pressure massage airbag 16 is opened, and the other first control valves 20 are closed. Gas enters the inflation chamber 50 of the knee-lower air pressure massage airbag 16 and is maintained thereafter. At the same time, the second control valve 23 connected to the calf air pressure massage airbag 17 is opened, and the gas in the calf air pressure massage airbag 17 is discharged, simulating the massage transition from the knee to the calf.

[0039] In the fourth stage, the first control valve 20 connected to the ankle air pressure massage airbag 18 is opened, while the other first control valves 20 are closed. Gas enters the inflation chamber 50 of the ankle air pressure massage airbag 18 and continues to flow, simulating massage of the foot and ankle. At the same time, the second control valve 23 connected to the knee air pressure massage airbag 16 is opened, and the gas in the knee air pressure massage airbag 16 is discharged, completing a full cycle.

[0040] The airbag applies pressure sequentially from ankle to calf to below the knee, then from ankle to calf to below the knee, and so on. This simulates the manual massage technique used by professional nurses, moving from the distal to the proximal end of the limb, creating a gradient pressure wave from bottom to top. This effectively promotes the return of blood from the deep veins of the lower limbs towards the heart, reducing the risk of deep vein thrombosis in long-term bedridden patients.

[0041] Meanwhile, the independent air intake and exhaust control of each airbag allows the massage rhythm and intensity to be flexibly adjusted according to the patient's needs, adapting to the requirements of different rehabilitation stages.

[0042] A limiting groove 6 is horizontally formed in the middle of both sides of the lower end face of the support base 2. The limiting groove 6 provides a guide track for the sliding of the C-shaped fastener 8 along the support base 2. A limiting slider 7 is limited to slide within the limiting groove 6, and the lower end of the limiting slider 7 is fixed to the C-shaped fastener 8. The length of the upper horizontal plate of the C-shaped fastener 8 is greater than the length of the lower horizontal plate of the C-shaped fastener 8. This difference in length between the upper and lower horizontal plates allows the C-shaped fastener 8 to have a larger clamping span when unfolded outward, making it easier to quickly fit into the edge of the bed. A fixing screw 9 is threadedly connected to the middle of the lower horizontal plate of the C-shaped fastener 8. A handwheel is provided at the lower end of the fixing screw 9, which can be driven to rotate by the caregiver. A fixing plate 10 is provided at the upper end of the fixing screw 9 inside the C-shaped fastener 8. The fixing plate 10 is rotatably connected to the fixing screw 9. The front and rear ends of the lower end of the fixing plate 10 are provided with vertical rods that slide along the lower horizontal plate limit of the C-shaped fastener 8. The vertical rods ensure that the fixing plate 10 does not rotate during the upward process and only moves in a vertical straight line.

[0043] The lower end of the support base 2 is connected to several anti-slip particles 5.

[0044] During installation, push the C-shaped fastener 8 outward to make the limiting slider 7 slide outward along the limiting groove 6. The distance between the two C-shaped fasteners 8 is greater than the distance of the bed. Place the device on the bed. The setting of the lower anti-slip particles 5 can reduce the displacement of the device.

[0045] Pushing the C-shaped fastener 8 inward causes the limiting slider 7 to slide inward along the limiting groove 6 until the inner side of the C-shaped fastener 8 is in close contact with the side of the bed edge. Rotating the handwheel at the lower end of the fixing screw 9 drives the fixing screw 9 to rotate, pushing the fixing cross plate 10 upward to abut against the lower end of the bed. As the fixing screw 9 continues to rotate, the fixing cross plate 10 is firmly pressed against the lower end of the bed, thus fixing the device.

[0046] like Figure 6 As shown, the front and rear ends of the foot limiting platform 25 are connected to acupoint units 27. The acupoint unit 27 includes two foot support plates 28 fixed to both sides of the front end of the foot limiting platform 25. The two foot support plates 28 are symmetrically arranged in the left-right direction, together forming the support surface of the sole. A flexible footrest 29 is attached to the front end of the foot support plates 28. The flexible footrest 29, attached to the front end of the foot support plates 28, can adapt to the foot contours of different patients, providing acupoint positioning while ensuring comfort during long-term use. Compared to rigid footrests, the flexible footrest 29 avoids pressure damage to the sole skin caused by rigid materials. A foot positioning groove 30 is formed in the middle of the front surface of the flexible footrest 29. The shape of the foot positioning groove 30 matches the contour of the human foot, so when the patient places their feet in, the soles naturally embed into the groove.

[0047] Multiple hemispherical massage elements 49 are installed within the foot positioning groove 30. These hemispherical massage elements 49 are made of medical-grade flexible silicone and can move alternately up and down. The foot acupoint unit 27 also includes two vertical action plates 41, located at the rear end of the foot support plate 28 and symmetrically arranged in the left-right direction. Multiple fixing sleeves 42 are fixed to the front end of each vertical action plate 41. The number of fixing sleeves 42 is the same as the number of hemispherical massage elements 49, and their front-to-back positions correspond one-to-one. The rotation axis of the hemispherical massage element 49 passes through the flexible footrest 29, the foot support plate 28, the foot limiting platform 25, and the fixing sleeves 42, extending rearward. The fixing sleeves 42 provide support for the rotation axis of the hemispherical massage element 49. The flexible footrest 29, foot support plate 28 and foot limiting platform 25 are all provided with vertical adjustment grooves 31 along the vertical movement trajectory of the hemispherical massage component 49. The vertical adjustment grooves 31 provide uninterrupted passage space for the vertical movement of the hemispherical massage component 49.

[0048] like Figure 7 and Figure 8 As shown, the foot acupoint unit 27 also includes two vertical drive threaded rods 35, which are located on the outer side of the rear end of the foot support plate 28 and are symmetrically arranged in the left-right direction. The upper and lower ends of the external surfaces of the vertical drive threaded rods 35 are threadedly connected to threaded sleeves 36, which can move up and down along the axial direction of the vertical drive threaded rods 35. A first connecting rod 37 is fixed to the front end of each threaded sleeve 36, and each set of two first connecting rods 37 is fixed to the upper and lower ends of the outer side of the rear end of the vertical action plate 41.

[0049] The foot acupoint unit 27 also includes a first drive motor 32 installed at the front end of the rear baffle 3. A first bevel gear 33 is installed on the output shaft of the first drive motor 32, and a second bevel gear 34 is meshed with the inner side of the first bevel gear 33. The second bevel gear 34 is installed in the middle of the outer side of the vertical drive threaded rod 35. The first drive motor 32 drives the first bevel gear 33 to rotate, and through the meshing transmission of the first bevel gear 33 and the second bevel gear 34, the power is transmitted to the vertical drive threaded rod 35 and drives it to rotate. Since the threaded sleeve 36 is threadedly connected to the vertical drive threaded rod 35, the rotation of the vertical drive threaded rod 35 is converted into the axial linear up-and-down movement of the threaded sleeve 36. The threaded sleeve 36 drives the vertical action plate 41 to move up and down synchronously through the first connecting rod 37, thereby driving the hemispherical massage element 49 inside the fixed sleeve 42 to move up and down alternately, realizing the massage mode. When the first drive motor 32 rotates forward, it drives the vertical drive threaded rod 35 to rotate through the meshing transmission of the first bevel gear 33 and the second bevel gear 34. The threaded sleeve 36 moves upward along the vertical drive threaded rod 35, driving the vertical action plate 41 and the hemispherical massage piece 49 to move upward, simulating the action of the thumb pushing upward. When the first drive motor 32 rotates in reverse, the threaded sleeve 36 moves downward, driving the hemispherical massage piece 49 to move downward, simulating the action of the thumb pushing downward.

[0050] A vertical fixing rod 38 is fixed to the inner side of the vertical drive threaded rod 35 at the front end of the rear baffle 3 via a fixing block. The vertical fixing rod 38 is vertically arranged, and its upper and lower ends are slidably connected to limit sleeves 39. A second connecting rod 40 is fixed to the front end of the limit sleeve 39, and two second connecting rods 40 in each group are respectively fixed to the upper and lower ends of the inner side of the rear end of the vertical action plate 41. The vertical fixing rod 38, the limit sleeve 39, and the second connecting rod 40 constitute an inner guiding constraint on the vertical action plate 41.

[0051] Multiple rear connecting rods 43 are fixed from top to bottom on both sides of the rear end of the vertical actuating plate 41. The rear connecting rods 43 are arranged along the height direction of the vertical actuating plate 41, with two rods in each row. A longitudinal actuating plate 44 is slidably connected to the two rear connecting rods 43 in each row. The longitudinal actuating plate 44 has an inverted "convex" shape. A pressure spring 45 is provided between the longitudinal actuating plate 44 and the vertical actuating plate 41 along the outside of the rear connecting rods 43. The pressure spring 45 provides a forward restoring force to the longitudinal actuating plate 44, ensuring that the distal end of the eccentric wheel 47 can pull the longitudinal actuating plate 44 back to the leading edge position during the non-contact phase.

[0052] A second drive motor 46 is installed at the lower end of the vertical moving plate 41 between the two rear connecting rods 43 in each row. An eccentric wheel 47 is installed at the output shaft end of the second drive motor 46, and the outer surface of the eccentric wheel 47 is in contact with the longitudinal moving plate 44. The second drive motor 46 drives the eccentric wheel 47 to rotate. When the far end of the eccentric wheel 47 (the point of maximum eccentricity) faces the longitudinal moving plate 44, it pushes the longitudinal moving plate 44 to move backward along the rear connecting rod 43. When the near end of the eccentric wheel 47 (the point of minimum eccentricity) faces the longitudinal moving plate 44, the elastic force of the pressure spring 45 pulls the longitudinal moving plate 44 forward to contact the near end of the eccentric wheel 47, realizing the rapid back-and-forth alternating movement of the longitudinal moving plate 44.

[0053] Multiple third drive motors 48 are installed at the rear end of the longitudinal motion plate 44, and the third drive motors 48 correspond one-to-one with the front and rear positions of the hemispherical massage element 49. The output shaft of the third drive motor 48 is connected to the rotation shaft of the hemispherical massage element 49, and the third drive motor 48 drives the hemispherical massage element 49 to rotate around its rotation shaft.

[0054] The specific working principles of the three massage modes are as follows:

[0055] Massage mode: The first drive motor 32 drives the first bevel gear 33 to rotate. The meshing connection between the first bevel gear 33 and the second bevel gear 34 drives the vertical drive threaded rod 35 to rotate. The threaded sleeve 36 moves up and down alternately along the vertical drive threaded rod 35. The vertical action plate 41 moves up and down synchronously through the first connecting rod 37, the limiting sliding sleeve 39, and the second connecting rod 40. The hemispherical massage piece 49 inside the fixed sleeve 42 moves up and down alternately synchronously with the vertical action plate 41, imitating the thumb massage technique.

[0056] Kneading and Pressing Mode: The third drive motor 48 drives the hemispherical massage pieces 49 to rotate independently around their rotation axis. The rotation speed and direction of each hemispherical massage piece 49 can be controlled individually, mimicking the thumb kneading technique. The kneading and pressing mode can be operated simultaneously with the massage mode, forming a compound action of massage and kneading, which provides a deeper and more comprehensive stimulation to the acupoints on the soles of the feet.

[0057] Tap mode: The second drive motor 46 drives the eccentric wheel 47 to rotate. When the distal end of the eccentric wheel 47 contacts the longitudinal action plate 44, it pushes the longitudinal action plate 44 to move backward along the rear connecting rod 43, causing the third drive motor 48 connected to the longitudinal action plate 44 to move backward, and the hemispherical massage piece 49 to move backward. When the proximal end of the eccentric wheel 47 faces the longitudinal action plate 44, due to the presence of the pressure spring 45, it pulls the longitudinal action plate 44 to contact the proximal end of the eccentric wheel 47, causing the third drive motor 48 connected to the longitudinal action plate 44 to move forward, and the hemispherical massage piece 49 to move forward.

[0058] The second drive motor 46 drives the eccentric wheel 47 to rotate. Through the contact between the outer surface of the eccentric wheel 47 and the longitudinal action plate 44, the hemispherical massage piece 49 moves back and forth rapidly, mimicking the thumb pressing technique.

[0059] Since each row of second drive motors 46 independently controls the feeding depth of the hemispherical massage pieces 49 in that row, the intensity and depth of the point press can be adjusted. Combined with the massage and kneading modes, it can achieve full coverage of intensity range from gentle to deep.

[0060] The three massage modes can be run individually, in any combination of two, or all three simultaneously. They comprehensively cover the three core techniques of traditional Chinese massage: "pushing, kneading, and pressing," enhancing the comprehensiveness and effectiveness of stimulation to acupoints on the soles of the feet. This can more effectively promote blood circulation in the soles of the feet, relieve foot fatigue, and improve nerve reflex function.

[0061] The inner surface of the foot wrap 26 is equipped with a graphene flexible heating layer, with heating circuitry extending outwards and connected to an external temperature control power supply. Graphene material possesses high thermal conductivity and far-infrared radiation properties, enabling it to rapidly heat up and emit far-infrared wavelengths compatible with the human body upon power application. This allows for deep penetration into the foot tissues, dilating microvessels and accelerating blood flow. Thermotherapy can be performed simultaneously with massage, effectively promoting blood circulation in the lower limbs.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
