Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a massage device for relieving arm pain. Background Technology

[0002] Pain is a subjective discomfort caused by damage to the body. Arm pain, as a common clinical symptom of physical discomfort, is mostly divided into two categories: acute pain and chronic pain. Acute pain is mostly caused by trauma or short-term high-intensity labor and lasts for a short period of time. Chronic pain, on the other hand, is mostly caused by long-term strain, improper posture, poor local blood circulation, etc., and lasts for more than 3 months. It has become a common health problem that affects people's daily work, life and limb activities.

[0003] With the accelerated pace of modern life and changing work patterns, arm pain is affecting a wider range of people, and the trend is towards younger ages. On the one hand, manual laborers and manual workers engage in repetitive, mechanical arm movements for extended periods, keeping their muscles in a state of constant tension and contraction, which easily leads to muscle strain and fascial adhesions, subsequently causing arm soreness and tingling. On the other hand, office workers, e-sports enthusiasts, and students maintain fixed postures such as hunching over desks and holding electronic devices for long periods, resulting in insufficient blood supply to the arms and muscle stiffness. Over time, this can lead to chronic arm pain, and in severe cases, numbness and limited mobility, not only reducing work and study efficiency but also affecting limb health and even inducing osteoarthritis such as frozen shoulder and tennis elbow.

[0004] A Chinese invention patent application (CN201910080297.X) discloses a massage device for relieving arm pain. The device mainly includes a main frame, a massage relief unit, a control device, and a power supply. The main frame is equipped with a music player and a timer. The massage relief unit includes a massage plate, a medicated heat pack, sliding massage components, a drive motor, a hydraulic telescopic rod, and a constant-temperature heater. It can not only massage the painful area but also apply medicated heat to enhance pain relief. However, the device is overly cumbersome to use and cannot seamlessly switch between massage and medicated heat application. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A massage device for relieving arm pain includes a massager connected to a main frame. The massager includes annular plates at both ends of a housing. The housing is fixedly connected to one end of an inner liner via the annular plates. An adjustment assembly is rotatably mounted between the housing and the inner liner. The adjustment assembly includes an auxiliary cylinder, a rotating cylinder, a push rod, a pressure plate, a support spring, a massage head, and a medicated hot compress pack. The auxiliary cylinder is fitted onto the inner liner and rotatably connected to the annular plates. Pressure plates are rotatably mounted on both the upper and lower ends of the auxiliary cylinder via rotating seats. Opposite faces of one end of the pressure plates are fixedly connected to the auxiliary cylinder via support springs. The other ends of the pressure plates are rotatably connected to the massage head and the medicated hot compress pack, which are vertically slidably mounted on the auxiliary cylinder. A rotating cylinder is fitted onto the auxiliary cylinder. A ratchet is fixedly mounted on one end of the rotating cylinder. The ratchet engages with two sets of opposite pawls mounted on an auxiliary plate at the end of the auxiliary cylinder. The rotating cylinder is rotatably connected to the housing. An arc-shaped groove is formed on the rotating cylinder. A guide rod is slidably mounted in the arc-shaped groove. The guide rod is fixedly connected to the outer wall of a push rod fitted onto the auxiliary cylinder and slidably mounted inside the rotating cylinder. The end of the push rod extending out of the rotating cylinder engages with the pressure plate.

[0007] A further preferred embodiment of the present invention: elastic bands are installed on opposite sides of the annular plate, and spaces for accommodating arms are provided in the middle of the elastic bands, the annular plate, the inner liner and the outer shell, and a space for accommodating massage heads and medicated hot compress packs is provided between one end of the inner liner and the annular plate.

[0008] A further preferred embodiment of the present invention is provided: a conical groove is provided on the inner wall of the end of the push rod extending out of the rotating cylinder, and the conical groove cooperates with the rotating wheel on the back side of one end of the pressure plate.

[0009] A further preferred embodiment of the present invention: a housing is fixedly installed on the top of the outer shell, and a drive gear driven by a motor is rotatably installed inside the housing. The drive gear meshes with a driven gear fixedly installed on the outer wall of the rotating drum.

[0010] A further preferred embodiment of the present invention is as follows: a flat support frame is fixedly installed at the bottom of the outer casing, and an anti-slip pad is provided on the bottom surface of the support frame.

[0011] A further preferred embodiment of the present invention is that two first electromagnets are provided on the auxiliary plate at the end of the auxiliary cylinder, and the first electromagnets are controlled to be connected to the corresponding pawls.

[0012] A further preferred embodiment of the present invention: an annular groove is provided on the inner wall of the outer shell, and a slider is slidably mounted on the outer shell through the annular groove. A brake assembly is provided on the contact surface between the slider and the groove. The brake assembly includes a second electromagnet, a brake rod, and an auxiliary spring. The brake rod is slidably mounted on the groove on the bottom surface of the slider. One end of the brake rod is connected to the groove, and a spring is also fitted on the brake rod. The spring is located in the groove. The other end of the brake rod is controlled and connected by the second electromagnet. A limit plate is fixedly mounted on the opposite surface of the slider and the rotating cylinder. A limit groove is provided on the limit plate along its length, and a guide rod is slidably mounted on the limit groove.

[0013] The present invention has the following advantages: 1. This invention precisely controls the linkage of the rotating cylinder, auxiliary cylinder, and push rod through the coordinated operation of ratchet, pawl, and adjustment components. It eliminates the need for complex disassembly and assembly or additional switching operations, quickly switching between massage head pressure massage and medicated hot compress therapy. This completely solves the problems of cumbersome, time-consuming, and laborious mode switching in existing devices. Targeting soreness and stinging caused by muscle strain and poor blood circulation in the arms, it relaxes stiff muscles, loosens fascia adhesions, and improves local blood supply through the mechanical pressure of the massage head, while the medicated hot compress provides both thermal therapy and drug penetration. This dual-effect synergistic approach relieves arm pain, catering to both the need for rapid relief of acute arm pain and long-term conditioning of chronic arm pain, resulting in a more comprehensive and efficient pain relief effect.

[0014] 2. This invention utilizes an elastic band for flexible wear. The design of the inner lining and the ring plate provides ample space for the massage head and medicated heat pack while conforming to the contours of the arm, preventing loosening or shifting and ensuring precise application of massage and heat to the painful area. A flat support frame with anti-slip pads at the bottom of the outer shell provides stability and prevents slippage or tipping, facilitating stationary use and reducing pressure on the arm. The flexible, form-fitting design of the inner lining, combined with the elastic support structure, prevents pressure marks and discomfort from prolonged use, balancing therapeutic effects with wearing comfort, and meeting the needs of extended soothing therapy.

[0016] 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.

[0017] according to Figure 1-6 As shown, a massage device for relieving arm pain includes a massager connected to a main frame. The remaining components of the main frame remain unchanged. The massager includes annular plates at both ends of a housing 1. The housing 1 is fixedly connected to one end of an inner liner via the annular plates. An adjustment assembly is rotatably mounted between the housing 1 and the inner liner. The adjustment assembly includes an auxiliary cylinder 7, a rotating cylinder 8, a push rod 9, a pressure plate 20, a support spring 21, a massage head, and a medicated hot compress pack 19. The auxiliary cylinder 7 is fitted onto the inner liner and rotatably connected to the annular plates. Pressure plates 20 are rotatably mounted on both the upper and lower ends of the auxiliary cylinder 7 via rotating seats 18. Opposite surfaces of one end of each pressure plate 20 are supported by... Spring 21 is fixedly connected to auxiliary cylinder 7. The other end of pressure plate 20 is rotatably connected to massage head and medicated hot compress pack 19, which are vertically slidably mounted on auxiliary cylinder 7. Rotary cylinder 8 is fitted on the outside of auxiliary cylinder 7. Ratchet 11 is fixedly installed on one end of rotary cylinder 8. Ratchet 11 is engaged with two sets of opposite pawls 12 installed on auxiliary plate 13 at the end of auxiliary cylinder 7. Rotary cylinder 8 is rotatably connected to outer shell 1. An arc groove 15 is provided on rotary cylinder 8. Guide rod 14 is slidably installed in arc groove 15. Guide rod 14 is fixedly connected to the outer wall of push rod 9, which is fitted on auxiliary cylinder 7 and slidably installed in rotary cylinder 8. The end of push rod 9 that extends out of rotary cylinder 8 is engaged with pressure plate 20.

[0018] Elastic bands 6 are installed on both sides of the ring plate. The elastic bands 6 can provide elastic tightening to securely wear the device on the painful part of the arm for easy use. The elastic bands 6, the ring plate, the inner liner and the outer shell 1 are all provided with space to accommodate the arm. One end of the inner liner and the ring plate are provided with space to accommodate the massage head and the medicated hot compress pack 19. The structure of the massage head and the medicated hot compress pack 19 remains unchanged.

[0019] A tapered groove is provided on the inner wall of the end of the push rod 9 that extends out of the rotating cylinder 8. The tapered groove cooperates with the rotating wheel 17 on one side of the pressure plate 20 to ensure the movement of the push rod 9 and control the rotating wheel 17. The tapered groove can drive the rotating wheel 17 to control the pressure plate 20 to move relative to or away from each other.

[0020] A housing 2 is fixedly installed on the top of the outer casing 1. A drive gear driven by a motor 3 is rotatably installed inside the housing 2. The drive gear meshes with a driven gear 10 fixedly installed on the outer wall of the rotating drum 8. Here, the motor 3 is a forward and reverse motor, which drives the driven gear 10 by driving the drive gear.

[0021] The bottom of the outer casing 1 is fixedly installed with a flat support frame 4. The bottom surface of the support frame 4 is provided with an anti-slip pad 5. The flat support frame 4 with anti-slip pad at the bottom of the outer casing 1 can stabilize the support device when placed and used, prevent sliding and tipping, facilitate static use, and reduce the pressure on the arm.

[0022] Two first electromagnets are provided on the auxiliary plate 13 at the end of the auxiliary cylinder 7. The first electromagnets are connected to the corresponding pawls 12. By controlling different first electromagnets, the engagement between the pawls 12 and the ratchet 11 can be changed, which can adapt to the forward and reverse rotation of the motor 3.

[0023] An annular groove is provided on the inner wall of the outer shell 1. A slider 22 is slidably installed on the outer shell 1 through the annular groove. A brake assembly is provided on the contact surface between the slider 22 and the groove. The brake assembly includes a second electromagnet 25, a brake rod 23 and an auxiliary spring 24. The brake rod 23 is slidably installed on the groove on the bottom surface of the slider 22. One end of the brake rod 23 is connected to the groove. A spring is also fitted on the brake rod 23 and is located in the groove. The other end of the brake rod 23 is controlled and connected by the second electromagnet 25. A limit plate 16 is fixedly installed on the opposite surface of the slider 22 and the rotating cylinder 8. A limit groove is provided on the limit plate 16 along its length. A guide rod 14 is slidably installed on the limit groove. This arrangement can ensure that the limit plate 16 can be controlled to rotate with the guide rod 14 or the linear movement of the guide rod 14 can be restricted at any time.

[0024] Working principle: When in use, the arm is inserted into the arm-accommodating space formed by the elastic band 6, the ring plate, the inner liner, and the middle of the outer shell 1. The elastic band 6 tightens securely, ensuring the device is worn firmly on the arm and the inner liner fits snugly against the skin, laying the foundation for subsequent massage and heat therapy. The space between the inner liner and the ring plate ensures sufficient movement for the massage head and the medicated heat pack 19, preventing parts from getting stuck or squeezing the arm and causing discomfort. When the device is placed, it is stably supported by the flat support frame 4 with anti-slip pads 5 at the bottom, preventing slippage and improving operational stability. After the device is started, the motor 3 inside the top box 2 of the outer shell 1 is powered on and drives the active gear. The wheels rotate synchronously, and the driving gear meshes with the driven gear 10 fixed to the outer wall of the rotating cylinder 8. The first electromagnet, controlling the pawl 12 to engage with the ratchet 11, determines the location of the pain. This ensures that the auxiliary cylinder 7 rotates simultaneously with the rotating cylinder 8, guaranteeing that the massage head is first rotated to the painful area. After the ratchet 11 and pawl 12 engage, the rotating cylinder 8, push rod 9, and auxiliary rod become a single unit. The power from the motor 3 is transmitted to the rotating cylinder 8, causing it, push rod 9, and auxiliary rod to rotate in a directional circular motion. Simultaneously, the guide rod 14 drives the limiting plate 16 to rotate. When the massage head reaches the designated position, the pawl 12 is disengaged from the ratchet 11, releasing the second electromagnet 25. The brake lever 23 extends under the action of the auxiliary spring 24, fixing the massage head in place. Limit plate 16, again controlling motor 3 to drive rotating drum 8, guide rod 14, under the limiting action of limit plate 16 and the guiding action of arc groove 15, drives push rod 9 to move linearly. The conical groove at the end of push rod 9, in conjunction with rotating wheel 17, under the action of support spring 21, causes pressure plate 20 to rotate in opposite directions, and massage head to press on the painful area. Massage head can then be turned on for massage. After the massage is completed, when adjusting the hot compress mode, the first electromagnet manipulates pawl 12 in conjunction with ratchet 11, so that when rotating drum 8 rotates, auxiliary drum 7 rotates simultaneously, ensuring that the medicated hot compress pack 19 rotates to the painful area. After ratchet 11 and pawl 12 are engaged, rotating drum 8, push rod 9, and auxiliary rod become a whole, and the power of motor 3 is transmitted to the rotating drum 8. The cylinder 8 drives the rotating cylinder 8, push rod 9, and auxiliary rod to rotate in a directional circular motion. At the same time, the guide rod 14 drives the limiting plate 16 to rotate. When the medicated hot compress pack 19 reaches the designated position, the pawl 12 is controlled to separate from the ratchet 11, releasing the second electromagnet 25. The brake rod 23 extends under the action of the auxiliary spring 24, fixing the limiting plate 16. The motor 3 is controlled again to drive the rotating cylinder 8 to rotate. Under the limiting action of the limiting plate 16 and the guiding action of the arc groove 15, the guide rod 14 drives the push rod 9 to move linearly. The conical groove at the end of the push rod 9 cooperates with the rotating wheel 17. Under the action of the support spring 21, the pressure plate 20 rotates in opposite directions, and the medicated hot compress pack 19 presses the painful area, opening the medicated hot compress pack 19 to perform hot compress work.
