Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a physical therapy device with a muscle massage function for upper limb rehabilitation. Background Art

[0002] In existing rehabilitation therapy equipment technology, devices used for upper limb or back muscle massage are mostly passive massagers with fixed structures and single functions. Common forms include vibrating patches, simple rollers, or fixed massage heads. These devices generally rely on the user's own body position adjustment or gravity contact to perform massage, lacking an active drive mechanism. Although they have a certain muscle relaxation effect, their rigid structure and poor adaptability make them difficult to flexibly adjust to the user's different body shapes and rehabilitation needs. Especially when used on complex curved surfaces or movable parts such as shoulders, arms, and backs, they often cannot achieve full fit and stable contact, resulting in separation and misalignment between the massage head and the target muscle, preventing the massage force from being effectively transmitted to deep tissues. This results in a lack of noticeable massage effect, poor comfort, and even secondary discomfort, seriously affecting the therapeutic effect.

[0003] Furthermore, traditional massage devices generally utilize a single mechanical vibration or simplified compression method, resulting in a relatively monotonous functional model. They are unable to simulate the rhythmic coordination of various massage techniques, such as kneading, pinching, grasping, lifting, and rotation, found in manual massage. They also struggle to dynamically adjust massage frequency, amplitude, and direction, and lack the ability to address the differentiated responses of muscle tissue in different areas. Consequently, these devices are unable to meet comprehensive rehabilitation needs, such as deep muscle relaxation, nerve activation, and fascial release. Their applicability is particularly limited in clinical scenarios, such as postoperative rehabilitation, hemiplegic muscle activation, and training of disused muscle groups. Summary of the Invention

[0004] In response to the above-mentioned problems, the present invention aims to provide a physical therapy device with muscle massage function for upper limb rehabilitation. Through the cooperation of contact mechanism, pushing mechanism and transmission mechanism, multiple massage modes are realized, simulating the kneading, pressing, grabbing and other compound techniques in artificial massage, which can achieve deep muscle fiber activation and comprehensive muscle relaxation, and significantly improve the rehabilitation treatment effect.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A physical therapy device with muscle massage function for upper limb rehabilitation includes a massage plate, characterized in that at least two movably connected massage strips are provided on the massage plate; each of the massage strips is provided with multiple massage mechanisms, and the massage mechanisms include: a contact mechanism, installed in the massage strip, used to massage the upper limb muscles; a pushing mechanism, connected to the contact mechanism, used to make the contact mechanism perform rotational massage; a transmission mechanism, connected to the contact mechanism, used to make the contact mechanism perform all-around diffuse massage.

[0006] With the cooperation of the contact mechanism, the pushing mechanism and the transmission mechanism, this physiotherapy device realizes a variety of massage modes, simulating the compound techniques of kneading, pressing, grabbing and lifting in manual massage, which can activate deep muscle fibers and relax comprehensive muscles, effectively promote blood circulation, excretion of metabolic products and nerve activation, and significantly improve the rehabilitation treatment effect.

[0007] Furthermore, the pushing mechanism includes a first base, two first adjusting members and two arc-shaped slide rails; the first base is installed on the massage bar; the two first adjusting members are installed on the top of the first base; the two arc-shaped slide rails are connected to the contact mechanism, and are respectively cooperated with the corresponding first adjusting members to rotate the contact mechanism.

[0008] The first adjusting member drives the slide rail to rotate along an arc track through linear telescopic motion, and a contact component is connected to the top of the slide rail, so its movement is converted into rotational motion of the contact component, thereby allowing the massage head to perform multi-angle rotational massage around a fixed point.

[0009] Furthermore, the contact mechanism includes a second base, multiple connecting tubes and multiple first massage heads; the second base is connected to the slide rail; the multiple connecting tubes are installed on the second base; and the multiple first massage heads are respectively installed on the connecting tubes.

[0010] Furthermore, the first massage head includes a massage head body, two second adjustment parts and a second massage head; the massage head body is connected to the connecting tube; the two second adjustment parts are installed in the massage head body, and are used to push the edge of the massage head body to deform for massage; the second massage head is installed at the center of the massage head body, and is used to push the center of the massage head body to deform for massage.

[0011] The two second adjustment parts can be extended and retracted at the same time to perform local massage. The third adjustment part drives the second massage head up and down to perform alternating massage. Through rhythmic circulation stimulation, it helps to enhance blood return to the muscles, promote the removal of metabolic waste, and improve the overall circulation efficiency.

[0012] Furthermore, the transmission mechanism includes a ring, two arc-shaped limit plates, two limit rods and a connecting rope; the ring is rotatably mounted on the first base and is mounted outside the contact mechanism; the two arc-shaped limit plates are connected to the ring and have arc-shaped limit grooves on their surfaces; one end of the two limit rods is movably set in the corresponding limit grooves, and the other end is rotatably connected to the massage bar; the connecting rope is used to connect the limit rod and the corresponding first massage head.

[0013] The limit plate, limit rod and elastic connecting rope in the transmission mechanism work together to drive the massage head to produce a diffuse reciprocating motion in all directions, simulating the manual "grabbing and pressing" action, pulling the muscle tissue in both vertical and horizontal directions, helping to relieve fascia adhesion, muscle stiffness and spasm, and improve tissue elasticity and the speed of motor function recovery.

[0014] Furthermore, the plurality of collars are driven to rotate synchronously via a synchronous belt.

[0015] Furthermore, a detachable connecting component is provided between two adjacent massage strips.

[0016] Furthermore, the detachable connecting assembly includes a rotating shaft and a fixing frame; the rotating shaft is movably arranged on both sides of one of the massage strips; the fixing frame is arranged on both sides of the other massage strip and is arranged in cooperation with the rotating shaft.

[0017] Furthermore, the method for using the aforementioned physiotherapy device with muscle massage function for upper limb rehabilitation is characterized by comprising the following steps: S1: Fix the physiotherapy device to the patient's arm or back; S2: Massage muscles through contact mechanisms; S3: The contact mechanism is pushed to perform rotation massage; S4: The contact mechanism is used to perform diffuse massage all around through the transmission mechanism.

[0018] The beneficial effects of the present invention are: 1. The physiotherapy device of the present invention combines a massage plate with multiple detachable massage strips, allowing the device to be flexibly configured according to the width of the upper limbs or back of different users, adapting to the personalized needs of different body shapes and different rehabilitation areas, thereby enhancing its versatility and flexibility. The rotating connection structure design of the massage strips allows a certain degree of relative rotational freedom between the massage strips, which helps the device adjust its angle and adapt its shape according to the curved surface characteristics of different usage areas. It is particularly suitable for areas with significant curvature, such as the upper limbs. When massaging the arm, the user can rotate the massage strips to fit the naturally curved contour of the arm, thereby achieving a closer and more uniform contact effect, improving the depth and accuracy of the first massage head's action on the muscle tissue, and avoiding a weakening of the massage effect due to insufficient contact.

[0019] 2. The first adjusting member in the pushing mechanism of the present invention begins to perform telescopic movement, and the slide rail connected to the first adjusting member undergoes synchronous rotational displacement. A contact mechanism is fixedly connected above the slide rail. The linear drive of the first adjusting member is converted into rotational movement of the contact mechanism through the arc trajectory of the slide rail, causing the massage head to rotate alternately clockwise / counterclockwise, providing three-dimensional dynamic stimulation to the back muscles from multiple angles, simulating artificial circular kneading, effectively relieving surface tension and deeply activating deep muscle fibers, improving the blood circulation and nerve response ability of local muscles.

[0020] 3. The two second adjustment members in the contact mechanism of this invention respectively control the longitudinal extension and contraction of the two sides of the first massage head, helping to focus stimulation on specific muscle groups or trigger points, relieving local soreness and muscle stiffness. Simultaneously, the third adjustment member drives the second massage head, arranged in the center of the first massage head, to perform vertical reciprocating pressure, penetrating deep into the muscles for targeted stimulation and enhancing the targeted and penetrating power of rehabilitation. The combined action of the second and third adjustment members achieves rhythmic alternating pressure, effectively alleviating muscle fatigue and activating tissue metabolism, with significant therapeutic benefits for chronic strain, muscle weakness, and postoperative rehabilitation.

[0021] 4. The synchronous belt in the transmission mechanism of the present invention meshes with multiple rings, driving all of them to rotate synchronously. The arc-shaped limit plate attached to the rings then drives the limit rod to slide within the limit groove. The end of the limit rod pulls the first massage head via an elastic connecting rope, causing the entire massage head to engage in a diffuse displacement motion along its periphery. This motion simulates the manual diffuse grasping and pressing massage technique, stretching and tractioning muscle fibers in both the longitudinal and transverse directions. This not only relaxes fascia and dissolves adhesions, but also effectively improves muscle stiffness or dysfunction caused by prolonged sitting and poor posture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0039] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "front end", "back end", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] Example 1: Refer to the attached Figure 1-15 The physiotherapy device with muscle massage function for upper limb rehabilitation shown in the figure includes a massage plate 1, on which at least two movably connected massage strips 2 are provided, and the massage strips 2 are rotatably connected to each other. A groove 21 is provided in the massage strip 2, and a plurality of massage mechanisms 3 are provided in the groove 21. The massage mechanism 3 includes a contact mechanism 4, a pushing mechanism 5 and a transmission mechanism 6: the contact mechanism 4 is installed in the massage strip 2 for massaging the upper limb muscles; the pushing mechanism 5 is connected to the contact mechanism 4 so that the contact mechanism 4 performs a rotational massage; the transmission mechanism 6 is installed in conjunction with the contact mechanism 4 so that the contact mechanism 4 performs a diffuse massage all around.

[0042] This modular design allows multiple massage strips 2 to be removably mounted on the massage plate 1, allowing for flexible addition and removal of these strips based on the user's arm width or desired massage area. The pivoting connection between the strips 2 enhances the device's fit and adjustable angle, adapting to the needs of various body parts. The recessed groove 21 houses the massage mechanism 3, reducing the overall thickness of the device. It should be noted that the massage plate 1 utilizes flexible materials, such as silicone, which not only enhances wearing comfort but also allows for natural bending and deformation during use, maximizing the massage contact area and enhancing the depth and uniformity of the massage.

[0043] The pushing mechanism 5 comprises a first base 51, two first adjustment members 52, and two curved slide rails 53. The first base 51 is mounted within the groove 21 and is provided with a housing 54. The two first adjustment members 52 are mounted on top of the first base 51. The two slide rails 53 are each configured to cooperate with and located above the corresponding first adjustment member 52. It should be noted that the first adjustment members 52 can be electric push rods, which engage the slide rails 53. The slide rails 53 are curved and gradually extend upward. The pushing mechanism 5 is linearly pushed along the slide rails 53 by the first adjustment members 52, causing the slide rails 53 to rotate, thereby generating a rotational massage motion in the massage mechanism 3, which is fixed to the top of the slide rails 53. The extension and retraction of the first adjustment member 52 causes the massage mechanism 3 to perform a reciprocating rotational motion. This reciprocating massage motion can affect muscle groups from multiple angles, activating deeper muscle fibers and nerve endings, and effectively improving muscle stiffness during rehabilitation.

[0044] The contact mechanism 4 includes a second base 41, four connecting tubes 42 and four first massage heads 43; the second base 41 is connected to the top of the slide rail 53; the four connecting tubes 42 are installed on the top of the second base 41; the four first massage heads 43 are installed on the top of the connecting tube 42. It should be noted that the connecting tube 42 and the first massage head 43 are made of elastic material. The second base 41 transfers the power of the first adjustment member 52 from the slide rail 53 to the massage head to achieve orderly transmission. The four connecting tubes 42 are arranged in a distributed manner to achieve multi-point simultaneous massage and enhance the massage coverage area. The connecting tube 42 and the massage head are made of elastic material, which can produce slight deformation during the massage process, helping the massage head to better fit the muscle curve and reduce mechanical impact. It is especially suitable for people with muscle tension or postoperative recovery period.

[0045] The first massage head 43 includes two second adjustment members 431, a second massage head 432, and a massage head body 434. The massage head body 434 is connected to the connecting tube 42. The two second adjustment members 431 are installed within the massage head body 434 and are used to push the edges of the massage head body 434 to deform for massage. The second massage head 432 is installed at the center of the massage head body 434 and is used to push the center of the massage head body 434 to deform for massage. A third adjustment member 433 is located at the bottom center of the massage head body 434 and is connected to the second massage head 432. It should be noted that the second adjustment members 431 and the third adjustment members 433 can be electric push rods. The second adjustment member 431 can drive both sides of the massage head body 434, while the third adjustment member 433 located in the center drives the second massage head 432 to move up and down. The second massage head 432 drives the center of the massage head body 434 to press deeply on the core area of the muscle, producing a combined massage effect of point and surface, significantly improving the targetedness, effectiveness and user experience of rehabilitation treatment, and is particularly suitable for rehabilitation scenarios such as postoperative muscle weakness, chronic muscle fatigue and neuromuscular dysfunction. During driving, the two second adjustment members 431 can simultaneously extend and retract to perform local point massage, and cooperate with the third adjustment member 433 to drive the second massage head 432 up and down to perform alternating massage. Through rhythmic "press-release" cycle stimulation, it helps to enhance blood return to the muscles, promote the removal of metabolic waste, and improve overall circulation efficiency.

[0046] A detachable connection assembly is provided between two adjacent massage strips 2. The detachable connection assembly includes a rotating shaft 22 and a fixing bracket 23. The rotating shaft 22 is movably disposed on either side of one massage strip 2, while the fixing bracket 23 is disposed on either side of the other massage strip 2 and cooperates with the rotating shaft 22. One end of the rotating shaft 22 is threadedly connected to the fixing bracket 23, while the other end of the rotating shaft 22 is a smooth, round shaft, allowing the massage strip 2 to rotate. While maintaining the massage strip 2 stationary, the rotating shaft 22 can be rotated to disengage the fixing bracket 23, allowing removal. It should be noted that a hole is provided on the side of the massage strip 2 to accommodate the rotating shaft 22. The length of the hole is greater than that of the rotating shaft 22. To remove the massage strip 2, the rotating shaft 22 is rotated toward the massage strip 2, separating the rotating shaft 22 from the fixing bracket 23. By threading the fixing bracket 23 to the rotating shaft 22, the massage strip 2 can be locked and removed, improving the modular maintenance capabilities and ease of use of the device. The massage bar 2 can be rotated and adjusted in angle under the drive of the rotating shaft 22, which is convenient for users to make personalized settings according to specific rehabilitation needs; when it is necessary to replace damaged parts or replace different functional modules, the user only needs to rotate the rotating shaft 22 to quickly realize disassembly and assembly, which significantly improves the versatility and maintenance efficiency of the product.

[0047] The massage plate 1 is provided with holes 11 and fixing ropes 12 on both sides, allowing for secure attachment when needed. This structural design facilitates the secure attachment of the massage plate 1 to the patient's back or other massage areas, preventing displacement of the massage position due to body movement or device slippage during use, thereby improving massage precision and stability. This structure enhances the device's securement and ease of use, contributing to improved overall effectiveness and safety.

[0048] The physiotherapy device in this embodiment operates as follows: During use, the appropriate number of massage strips 2 is installed based on the patient's arm size. The angles can be adjusted to accommodate the arm's shape via the rotating shaft 22, and then secured by the fixing rope 12 inserted into the hole 11. The massage strips 2 are held stationary and the fixing bracket 23 is disengaged by rotating the rotating shaft 22 to remove them. To reinstall, simply rotate the rotating shaft 22 in the opposite direction to reinstall it. First, the first adjustment member 52 undergoes telescopic movement, and the slide rail 53 engaged with it rotates accordingly. The contact mechanism 4 is connected above the slide rail 53. The linear motion of the first adjustment member 52 is converted by the slide rail 53 into rotational motion of the contact mechanism 4, achieving a dynamic rotary massage that stimulates both the superficial and deep layers of muscle tissue from multiple angles. Two second adjustment members 431 control the longitudinal movement of the massage head body 434, providing a massage effect. The third adjustment member 433 drives the second massage head 432 to press vertically up and down, creating an alternating massage effect. This device can also massage the patient's back. The patient places the massage board 1 on the patient's back and installs an appropriate number of massage strips 2 according to the width of the patient's back. The patient lies on the massage board 1 and the fixing rope 12 can be passed around the patient's chest and inserted into the hole 11 for fixing, and then massage can be performed. The principle of the specific massage steps is the same as that of massaging the arms.

[0049] Example 2: Based on Example 1, Example 2 provides a specific structure of a transmission mechanism 6, comprising a collar 61, two arcuate limiting plates 62, two limiting rods 63, and two connecting ropes 65. The collar 61 is rotatably mounted on the housing 54 and sleeved outside the contact mechanism 4. The two arcuate limiting plates 62 are connected to the top of the collar 61 and have arcuate limiting grooves 66 formed on their surfaces. The two limiting rods 63 have one end movably positioned within the corresponding limiting grooves 66 and the other end rotatably connected to the massage bar 2. The collars 61 are synchronously driven for rotation by a synchronous belt 64, which engages with the collars 61 and is equipped with a motor. The connecting rope 65 is disposed between the limiting rods 63 and the first massage heads 43, and is connected to the two first massage heads 43. It should be noted that the connecting rope 65 is made of an elastic material, such as silicone, to facilitate resetting the reciprocating motion. The transmission mechanism 6 is driven by a motor to drive the synchronous belt 64 to rotate, and the synchronous belt 64 drives the engaged ring 61 to rotate, and the ring 61 drives the arc-shaped limit plate 62 to rotate, so that the limit rod 63 moves along the limit groove 66. The limit rod 63 pulls the connecting rope 65 to pull the first massage head 43 down, thereby guiding the first massage head 43 to move synchronously with the ring 61, realizing a dynamic massage trajectory that diffuses all around. The synchronous belt 64 reciprocates, causing the first massage head 43 to diffuse reciprocating motion, simulating the grabbing and pressing action of manual massage, which can apply longitudinal and lateral dual traction to muscle fibers, effectively relieving muscle adhesion, stiffness or spasm, and improving tissue elasticity.

[0050] The physiotherapy device in this embodiment operates as follows: a motor drives a synchronous belt 64, which engages with multiple collars 61, causing the collars 61 to rotate synchronously, further driving the rotation of the limiting plate 62. The limiting rod 63 moves within the limiting slot 66, pulling the connecting rope 65, which in turn pulls the first massage head 43 in a diffused displacement along its periphery, achieving a reciprocating, grasping, and pressing motion of the entire first massage head 43.

[0051] Specific application cases: When it is necessary to massage the patient's arms and back, the specific application method of the physiotherapy device with muscle massage function for upper limb rehabilitation of the present application is as follows: During use, the appropriate number of massage strips 2 is installed based on the patient's arm thickness. The angles of the rotating shafts 22 can be adjusted to accommodate the arm's shape. The fixing cords 12 are then inserted into the holes 11 for securement. The flexible structure of the massage plate 1 allows it to closely conform to the contours of the back, improving the contact stability and force uniformity between the first massage head 43 and the skin. First, the first adjustment member 52 begins to extend and retract, and the slide rail 53 engaged with the first adjustment member 52 undergoes synchronous rotational displacement. The contact mechanism 4 is fixedly connected to the upper portion of the slide rail 53. The linear drive of the first adjustment member 52 is converted into rotational movement of the contact mechanism 4 through the arc-shaped trajectory of the slide rail 53, causing the massage head to rotate alternately clockwise and counterclockwise, providing three-dimensional dynamic stimulation to the back muscles from multiple angles. This simulates artificial circular kneading, effectively relieving surface tension and deeply activating deep muscle fibers, improving blood circulation and neural response in the local muscles. The two second adjustment members 431 control the longitudinal extension and contraction of the two sides of the massage head body 434, helping to focus on stimulating specific muscle groups or trigger points, relieving localized soreness and muscle stiffness. Simultaneously, the third adjustment member 433 drives the second massage head 432, positioned at the center of the first massage head 43, to perform vertical reciprocating pressure. The second massage head 432 drives the center of the massage head body 434 to press deeply into the muscles, providing targeted stimulation and enhancing the targeted and penetrating effect of rehabilitation. The combined action of the second and third adjustment members 431 and 433 creates a rhythmic, alternating pressure pattern, effectively alleviating muscle fatigue and activating tissue metabolism. This provides significant therapeutic benefits for chronic strain, muscle weakness, and postoperative rehabilitation. Simultaneously, a motor drives the synchronous belt 64, mounted on the outer side of the massage bar 2, to rotate. The synchronous belt 64 engages with the multiple rings 61, driving all of the rings 61 to rotate synchronously. The arc-shaped limit plate 62 attached to the rings 61 then drives the limit rod 63 to slide within the limit slot 66. The end of the limit rod 63 pulls the first massage head 43 via an elastic connecting rope 65, causing the entire massage head to perform a diffuse displacement motion along its periphery. This motion simulates the manual, diffuse, grasping, and pressing massage technique, stretching and pulling muscle fibers in both the longitudinal and transverse directions. This not only relaxes fascia and dissolves adhesions, but also effectively alleviates muscle stiffness or dysfunction caused by prolonged sitting and poor posture.

[0052] In addition, the physiotherapy device of the present invention can also be used to massage the patient's back. When massaging the patient's back, the massage board 1 is placed on the patient's back, and an appropriate number of massage strips 2 are installed according to the width of the patient's back. Then the patient lies on the massage board 1, and the fixing rope 12 can be passed around the patient's chest and inserted into the hole 11 for fixing, and then massage is performed. The specific massage principles and steps are the same as the principle steps for massaging the arms.

[0053] Combined with overall rhythm control, this structure can also form regular massage rhythm and strength changes, enabling the neuromuscular system to produce a more stable feedback response and enhance the rehabilitation training effect.
