Description

Technical Field

[0001] This application relates to the field of arthritis treatment sleeves, and in particular to a hand auxiliary treatment sleeve for rheumatoid arthritis. Background Technology

[0002] Rheumatoid arthritis is a chronic, systemic autoimmune disease characterized by erosive, symmetrical polyarthritis. Its pathogenesis is closely related to autoimmune abnormalities, leading to inflammation and proliferation of the synovial membrane, which in turn destroys articular cartilage and bone, potentially causing joint deformities and loss of function. The disease commonly affects small joints such as the hands and wrists. Patients often experience pain, swelling, and stiffness in the hand joints. As the disease progresses, finger joint deformities may also occur (such as swan neck or buttonhole deformities), severely affecting basic hand functions such as grasping and flexion / extension, and reducing quality of life.

[0003] Current hand support sleeves for rheumatoid arthritis are a type of rehabilitation aid with the core objectives of "relieving symptoms, protecting joints, and maintaining function," and their design and functions are diverse. Functionally, most sleeves provide basic warmth and mild compression, using medical-grade elastic fabrics (such as a blend of spandex and cotton) to conform to the hand, improve local blood circulation, and reduce joint swelling and soreness. Some products for moderate to severe joint instability add flexible support structures (such as built-in thin memory foam pads or elastic bandages) to key areas such as the wrist and metacarpophalangeal joints, reducing wear and tear on the joints during movement and slowing the progression of deformities without restricting basic hand movements.

[0004] However, the aforementioned existing technologies still have some limitations in the treatment of rheumatoid arthritis: Existing treatment sleeves are lightweight sleeves designed for everyday household chores and office scenarios. They are mainly designed for lightweight wear and mostly use thin medical elastic fabrics (such as low-weight spandex cotton blends). Although they can ensure basic breathability and avoid stuffiness from wearing them for a long time, due to the thin material and simplified support structure, they can only provide slight warmth and distribute local pressure. They have limited effect on relieving pain and swelling caused by joint inflammation.

[0005] While thicker hand warmers designed specifically for nighttime care offer superior warmth and support—locking in hand heat and improving blood circulation at night with thicker fleece lining or warm fabric, and providing gentle support at the wrist and metacarpophalangeal joints with reinforced elastic bands or built-in support pads to reduce stiffness and pain at night and improve sleep quality—the excessive thickness significantly reduces hand freedom of movement. If the hand is accidentally compressed while turning over at night, it can feel restrictive. Some patients may even experience slight numbness in their fingers due to excessive wrapping, affecting sleep comfort.

[0006] Based on the above viewpoints, there is still room for improvement in existing technologies for the treatment of rheumatoid arthritis. Summary of the Invention

[0007] To address the aforementioned technical problems, this application provides a hand support sleeve for rheumatoid arthritis, employing the following technical solution: A hand support sleeve for rheumatoid arthritis includes a glove with open fingertips for easy hand operation. The glove has a palm side and a back side, a wrist side, and a pressure control element. The pressure control component includes a cavity in the internal structure of the glove, which divides the glove into an outer layer and an inner layer. The outer layer is made of heat-insulating material, and the inner layer is made of elastic material. The glove is equipped with a water injection valve that communicates with the cavity. The water injection valve is located on the back of the hand. By opening and closing the water injection valve, liquid can enter and exit the cavity. A heater is provided on the back of the hand.

[0008] Preferably, the pressure control component also includes a cavity extending to the wrist, an airbag is provided in the cavity of the wrist, an air valve is provided on the airbag, and the air valve extends to the outside of the wrist. The air valve is used to control the entry and exit of external air into the airbag.

[0009] Preferably, the outer and inner layers of the palm surface are thinner than the back of the hand.

[0010] Preferably, a circulation component is provided inside the cavity; The circulation component includes a diaphragm disposed inside the cavity, which divides the cavity into an upper cavity and a lower cavity. The upper cavity corresponds to the back of the hand, and the lower cavity corresponds to the palm. The cavity in the wrist connects the upper and lower cavities.

[0011] Preferably, the diaphragm has several through holes that connect the upper cavity and the lower cavity.

[0012] Preferably, a barrier is provided inside the cavity at the metacarpophalangeal joint, the barrier is located inside the cavity on the back of the hand, and a circulation zone is formed inside the barrier.

[0013] Preferably, an elastic membrane is provided on the circulation zone.

[0014] Preferably, the enclosure is equipped with multiple one-way valves; Four of the one-way valves correspond to the finger sections of the glove, and one of the one-way valves is connected to the cavity on the other side.

[0015] Preferably, the one-way valve includes a connecting frame passing through the enclosure, a stop block slidably disposed inside the connecting frame, and a return spring disposed between one side of the stop block and the connecting frame; A water outlet is provided on the connecting frame.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention uses a triple pressure control method, which adjusts the pressure of the wrist airbag by regulating the amount of medication injected, and dynamically adjusts the pressure by hand movements. Patients can choose the pressure level according to their condition and the situation. When doing light work activities, the low pressure level can be used to relieve mild soreness without affecting operation. When joint swelling and pain worsen, the medium pressure level can be used to reduce synovial congestion and edema. When resting at night, the low to medium pressure level can be flexibly selected to avoid a feeling of restraint and relieve morning stiffness.

[0017] The wrist airbag features a convenient valve design; simply press to inflate and direct the flow of medication and adjust the pressure. The pressure relief button quickly reduces the pressure. Combined with the resistance effect of the through-hole during hand movements, the pressure dynamically changes with hand actions, ensuring both therapeutic efficacy and improved wearing comfort, catering to the personalized needs of different disease stages and usage scenarios.

[0018] 2. This invention separates the upper and lower cavities using a diaphragm, forming a complete circulation channel with the wrist cavity and an independent circulation zone constructed by an elastic membrane. Combined with the directional guidance of a one-way valve, this creates a drug circulation mechanism driven by hand movement, where the elastic membrane expands and contracts, and the one-way valve guides the flow of the medication. When the hand extends, the elastic membrane expands, generating negative pressure that draws the medication from the fingers back to the circulation zone. When the hand contracts, the elastic membrane compresses the circulation zone, pushing the medication through the one-way valve to the lower cavity on the palm side. Repeated movement ensures stable circulation of the medication within the finger cavities. This stable circulation ensures even coverage of the metacarpophalangeal joints, proximal interphalangeal joints, and other areas prone to inflammation, preventing local medication stagnation or treatment blind spots, significantly improving drug utilization and treatment targeting.

[0029] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0030] This application discloses a hand support sleeve for rheumatoid arthritis. The elastic film stretches and contracts through hand movements, and with the help of a one-way valve for directional flow, the medication is circulated between the fingers, circulation area, and palm cavity, covering the inflammatory area of ​​the joints.

[0031] Reference Figure 1 and Figure 2 As shown, a hand aid for rheumatoid arthritis includes a glove 1. The fingertips of the glove 1 are open to facilitate hand operation. The fingertips are not covered, which preserves the flexibility of the fingertips, allowing patients to smoothly perform fine operations such as typing, writing, and using electronic devices. It also avoids stuffiness, sweating, or friction discomfort caused by prolonged covering of the fingertips. It is perfectly suited for high-frequency scenarios such as daily office work and housework, and solves the core problem of existing thin gloves 1 affecting hand operation.

[0032] The glove 1 is divided into a palm side 11 and a back side 12. One side of the glove 1 has a wrist 13. The wrist 13 can be made of highly elastic fabric with adjustable Velcro, which can achieve light fixation and warmth of the wrist joint without affecting the normal rotation of the wrist 13, further strengthening the protection of the wrist joint, a common site of rheumatoid arthritis.

[0033] Reference Figure 2 and Figure 3As shown, the glove 1 is equipped with a pressure control component 2; the pressure control component 2 is used to control the amount of pressure applied to the hand by the glove 1, allowing the patient to control the pressure according to their own condition and usage scenario: during daily office work and light activities, the low setting provides light pressure, which only needs to relieve mild soreness and improve local circulation without affecting hand operation; when joint swelling is obvious and pain is aggravated, the medium setting provides moderate pressure, which reduces synovial congestion and edema through appropriate pressure and enhances the analgesic effect; when resting at night, the low to medium setting can be selected according to sleep comfort, which, together with the warmth function of the glove 1, can relieve joint stiffness at night without causing a feeling of restraint.

[0034] Specifically, the pressure control component 2 includes a cavity 21 inside the glove 1, and the cavity 21 divides the glove 1 into an outer layer 22 and an inner layer 23. The outer layer 22 is made of heat-insulating material, and the inner layer 23 is made of elastic material.

[0035] The glove 1 is equipped with a water injection valve 24 that communicates with the cavity 21. The water injection valve 24 is located on the back of the hand 12, which experiences less force and friction in daily life, thus preventing damage to the valve or interference with operations such as typing and gripping. It also provides a wide field of vision, allowing patients with limited joint mobility to open and close the valve independently. The water injection valve 24 uses a medical-grade silicone press-type sealing structure, which is convenient to open and close and has a strong seal to prevent leakage of medication. Opening and closing the water injection valve 24 allows liquid to enter and exit the cavity 21.

[0036] The therapeutic liquid (such as concentrated Chinese herbal medicine for anti-inflammatory and analgesic purposes, or medical soothing liquid) is injected into the cavity 21 through the water injection valve 24. The amount of liquid injected can directly control the pressure of the cavity 21. When a small amount is injected, the pressure is low, which is suitable for daytime office and housework scenarios. The slight pressure, combined with the gentle penetration of the liquid, relieves soreness without affecting hand dexterity. When an appropriate amount is injected, the pressure increases, and the inner layer 23 adheres tightly to the skin, which not only accelerates the penetration of the liquid but also enhances the anti-inflammatory and analgesic effect, making it suitable for use at night or when the pain intensifies. The outer layer 22, which is made of heat-insulating material, can also maintain the temperature of the liquid and prolong the efficacy.

[0037] A heater 14 is provided on the back of the hand 12. The heater 14 can be powered by low voltage (such as USB rechargeable design, compatible with daily power supply or power bank) to achieve multi-level temperature control (usually set at a temperature that is comfortable for human body to apply heat). When the patient injects the treatment solution, the heater 14 is turned on to maintain the temperature of the solution in the optimal penetration range. The warm solution can not only reduce skin irritation, but also dilate the capillaries in the hand and accelerate local blood circulation, allowing the anti-inflammatory and analgesic ingredients in the solution to penetrate more quickly through the pores of the elastic material in the inner layer 23 to the joint inflammation site. The efficacy utilization rate is improved compared with the solution at room temperature, which is especially suitable for patients in autumn and winter or those with poor blood circulation in the hands.

[0038] Secondly, the heat therapy of the heater 14 and the heat insulation material of the outer layer 22 form a double heat-locking effect. The heat generated by the heater 14 is conducted to the cavity 21 through the back of the hand, while the heat insulation material of the outer layer 22 can reduce the loss of heat to the outside, so that the hand can maintain a constant temperature heat therapy state. This avoids the problem of traditional thickened protective sleeves relying solely on material for warmth and easy heat loss. Even in low temperature environments, it can maintain a comfortable hand temperature for a long time, and the effect of relieving morning stiffness symptoms is more significant.

[0039] Continue to refer to Figure 2 and Figure 3 As shown, the pressure control component 2 also includes a cavity 21 extending to the wrist 13. An airbag 25 is provided in the cavity 21 of the wrist 13, and an air valve 26 is provided on the airbag 25. The air valve 26 extends to the outside of the wrist 13.

[0040] The air valve 26 is used to control the entry and exit of external air into the airbag 25; by pressing, the airbag 25 can be inflated, and the airbag 25 gradually expands in the wrist 13, which can squeeze the medicine into the hand position, and at the same time can adjust the liquid pressure in the glove 1.

[0041] After the patient injects the therapeutic solution into the cavity 21 through the water injection valve 24, pressing the air valve 26 causes the airbag 25 to gradually inflate. The inflated airbag 25 will generate an outward squeezing force in the cavity 21 of the wrist 13. Since the cavity 21 is completely open, this squeezing force will directionally push the solution to the treatment area of ​​the hand along the channel of the cavity 21, accurately delivering the solution to the core area of ​​inflammation such as the metacarpophalangeal joints and proximal interphalangeal joints, avoiding the problem of insufficient local efficacy caused by the deposition of the solution in the cavity 21. At the same time, the pressure generated by the expansion of the airbag 25 will act synchronously on the liquid medicine in the cavity 21, so that the liquid pressure in the glove 1 changes dynamically with the inflation of the airbag 25. When the air valve 26 is pressed less often, the inflation of the airbag 25 is small and the liquid pressure is low, which is suitable for daytime office and housework scenarios. The mild pressure combined with the targeted delivery of the liquid medicine can relieve mild soreness without affecting the dexterity of the hand.

[0042] When the number of presses is increased to fully inflate the air bladder 25, the liquid pressure increases. At this time, the liquid medicine penetrates more quickly through the pores of the elastic material of the inner layer 23 to the inflamed joint area under the pressure. Combined with the warming effect of the heater 14 on the back of the hand 12, the penetration efficiency of the medicine is improved. It is especially suitable for use at night or when joint pain is aggravated, and can effectively reduce joint stiffness and inflammatory pain.

[0043] In addition to its air intake function, the air valve 26 also features a pressure relief button. If the patient feels that the liquid pressure is too high or experiences discomfort in their hand, they can simply press the pressure relief button to release the air in the airbag 25 and reduce the pressure in the cavity 21. This operation is convenient, safe, and controllable. The through-hole design between the wrist airbag 25 and the hand cavity 21 allows the medication to evenly cover all treatment areas of the hand under pressure, avoiding the "treatment blind spots" that may occur with traditional local drug delivery. Furthermore, the airbag 25 is located in the wrist 13 and is made of a flexible material. Even when inflated, it does not restrict wrist movement like a thicker protective sleeve. Patients can still move their wrists flexibly while wearing it, making it suitable for daily operations such as typing and grasping objects.

[0044] In addition, during the wearing process, for patients who need to move their hands for a long time (such as doing housework or light office work), the flow of the medicine generated by the hand movements can continuously provide drug efficacy support to the joints, avoiding drug displacement and treatment interruption due to activity; for patients with weak joint mobility, even if the range of hand movements is small, the squeezing force generated by slight flexion, extension and rotation can push the medicine to flow slowly, ensuring that the treatment can be achieved without relying on high-intensity movements.

[0045] The outer layer 22 and inner layer 23 of the palm surface 11 are thinner than the back of the hand 12. The outer layer 22 of the palm surface 11 is mostly made of thin, breathable, and heat-insulating cotton, while the inner layer 23 is made of low-weight, high-elastic spandex. The outer layer 22 of the back of the hand 12 is made of a slightly thicker, high-density heat-insulating material (such as thickened medical fleece), while the inner layer 23 is an elastic fabric of moderate thickness.

[0046] The palm 11 is the core force-bearing area for hand grasping, pressing, typing and other actions. The thinner material reduces the sense of obstruction when in contact with tools, keyboards and other objects, retains clear tactile feedback, avoids grip slippage, and is suitable for the operation needs of housework and office scenarios. The back of the hand 12 is an important bearing area for therapeutic functions. The slightly thicker outer layer 22 material can enhance the heat retention capacity, while the inner layer 23 material can provide a stable space for the liquid medicine in the cavity 21. At the same time, the appropriate elastic tension guides the direction of liquid medicine flow to avoid leakage.

[0047] When in use, the thinner material on the palm side (11) is more elastic and can closely fit the curvature of the palm, reducing friction and discomfort; the slightly thicker material on the back of the hand (12) can provide soft support, avoid discomfort caused by direct contact between related parts and the skin, and balance the overall weight of the cover, reducing fatigue from wearing it for a long time.

[0048] Reference Figure 4 , Figure 5 and Figure 6As shown, a circulation element 3 is installed inside the cavity 21. The circulation element 3 assists in squeezing during hand movements, guiding the medication to cover the entire cavity 21, avoiding "treatment blind spots" such as knuckles and palmar joints. On the other hand, the guiding effect of the circulation element 3 reduces the disordered flow of the medication within the cavity 21, lowering the risk of irritation caused by repeated friction of the medication against the same area of ​​skin. Combined with the high fit of the thin material on the palm side 11 and the soft support of the thick material on the back of the hand 12, the wearing comfort is further enhanced. Specifically, the circulation component 3 includes a diaphragm 31 installed inside the cavity 21, which divides the cavity 21 into an upper cavity 32 and a lower cavity 33. The diaphragm 31 installed inside the cavity 21 is made of a thin medical flexible film material (such as medical-grade polyurethane film), which divides the cavity 21 into an upper cavity 32 and a lower cavity 33 laterally along the hand. The upper cavity 32 corresponds to the back of the hand 12. Because the outer layer 22 and inner layer 23 of the back of the hand 12 are thicker, the upper cavity 32 has a larger volume and can hold more liquid medicine. At the same time, it provides sufficient space for heat conduction for the heater 14 of the back of the hand 12. The lower cavity 33 corresponds to the palm surface 11. To fit the thinner material design of the palm surface 11, the lower cavity 33 has a slightly smaller volume, which can reduce the amount of liquid medicine remaining on the palm surface 11 and avoid affecting daily operations such as gripping and typing.

[0049] The cavity 21 of the wrist 13 connects the upper cavity 32 and the lower cavity 33. The cavity 21 of the wrist 13 serves as a connecting hub, directly connecting the upper cavity 32 and the lower cavity 33, forming a complete circulation channel of "upper cavity 32 - cavity 21 of wrist 13, lower cavity 33", providing a basic path for the flow of medicine between different chambers.

[0050] To facilitate the exchange of medication between the upper cavity 32 and the lower cavity 33, the diaphragm 31 has several through holes 34 that connect the upper cavity 32 and the lower cavity 33. When the patient's hand is at rest, the medication can flow slowly through the through holes 34, achieving basic exchange between the upper cavity 32 and the lower cavity 33. However, when the hand moves (such as clenching a fist or extending it), the squeezing action of the elastic membrane 37 and the hand muscles will push the medication to rush rapidly towards the through holes 34. At this time, the narrow diameter of the through holes 34 will moderately impede the rapidly flowing medication, preventing the medication from passing through instantly, thus creating local pressure within the cavity 21.

[0051] For example, when a fist is clenched, the elastic membrane 37 on the back of the hand 12 contracts, propelling the liquid medicine in the circulation zone 36 to flow rapidly into the through hole 34 of the diaphragm 31. The obstruction effect of the through hole 34 causes the liquid medicine to accumulate briefly in the circulation zone 36 and the upper cavity 32, gradually increasing the pressure and acting on the metacarpophalangeal joints on the back of the hand, thus enhancing the anti-inflammatory and analgesic effect. At the same time, some of the liquid medicine overcomes the obstruction and flows downward through the through hole 34, forming secondary pressure in the lower cavity 33 (palm side). Combined with the conductivity of the thin material on the palm surface 11, the pressure is evenly distributed across the palm side joints, avoiding local pressure loss.

[0052] The lower cavity 33 of the palm 11 has a small volume and thin material. The pressure generated by the obstruction of the through hole 34 can be quickly transmitted to the joint on the palm side through the thin inner layer 23 material, and the pressure distribution is more uniform, avoiding pressure loss due to the operation requirements of the palm 11. The lower cavity 33 of the back of the hand 12 has a large volume and thick material. The pressure generated by the obstruction of the through hole 34 can act on the joint more persistently in the space wrapped by the thick material. Combined with the heat insulation material of the outer layer 22, the pressure and heat therapy have a superimposed effect, improving the efficiency of drug penetration.

[0053] In addition, the dynamic blocking pressure of the through-hole 34 requires no additional operation and is achieved entirely through the patient's daily hand activities. This avoids the cumbersome operation of traditional pressure devices and allows pressure therapy to be deeply integrated into daily life. Patients can enjoy pressure-assisted therapy while typing, grasping objects, and other actions, further improving ease of use and treatment continuity.

[0054] Reference Figure 5 , Figure 6 and Figure 7 As shown, a barrier 35 located at the metacarpophalangeal joint is provided within the cavity 21. The barrier 35 is located within the cavity 21 on the back of the hand 12, forming a circulation zone 36. An elastic membrane 37 is provided on the circulation zone 36. Multiple one-way valves 4 are provided on the barrier 35. Four of the one-way valves 4 correspond to the fingers of the glove 1, allowing only the liquid medicine in the circulation zone 36 to flow into the finger cavity 21; one of the one-way valves 4 is connected to the other cavity 21. This allows for one-way flow of the liquid medicine between the circulation zone 36 and the lower cavity 33.

[0055] When the patient performs hand movements (such as extending fingers, opening the palm, etc.), the skin on the back of the hand 12 will stretch accordingly. At this time, the elastic membrane 37 covering the top of the circulation zone 36 will stretch and deform synchronously. Since the elastic membrane 37 is made of highly elastic medical-grade silicone material, its stretching process will create a brief negative pressure environment in the circulation zone 36, providing directional suction for the flow of the drug solution.

[0056] The negative pressure environment will directly trigger the dynamic response of the one-way valves 4 on the side wall of the enclosure 35: the four one-way valves 4, which correspond one-to-one with the cavities 21 of the four fingers of the glove 1, will open instantly under the action of negative pressure suction because the flow direction is preset to the circulation zone 36 to the fingers; since the flow direction of the one-way valves 4 is the circulation zone 36 of the cavity 21, no medicine flows back in due to the negative pressure, and they remain closed.

[0057] At the moment the one-way valve 4 opens, the liquid medicine in the finger cavity 21 will flow from the finger cavity 21 to the circulation zone 36 under the pull of the negative pressure in the circulation zone 36, completing the return flow of the liquid medicine from the finger to the circulation zone 36; when the hand activity switches to actions such as clenching a fist and bending the fingers, the skin on the back of the hand 12 contracts, and the elastic membrane 37 squeezes the circulation zone 36, increasing the pressure in the circulation zone 36. At this time, the one-way valve 4 corresponding to the finger automatically closes due to its one-way conduction characteristic, preventing the liquid medicine from flowing back to the finger, while the one-way valve 4 connected to the lower chamber 33 opens under the pressure, pushing the liquid medicine in the circulation zone 36 to the lower chamber 33.

[0058] When the hand extends again and the elastic membrane 37 re-expands, the one-way valve 4 corresponding to the fingers will reopen. Under the combined effect of the negative pressure in the circulation zone 36 and the hand movement, the medicine in the lower cavity 33 flows to the finger cavity 21 after being transferred through the circulation zone 36, forming a medicine delivery path from the upper cavity 32 to the circulation zone 36 and then to the fingers. Through repeated extension and contraction of the hand, the expansion and compression of the elastic membrane 37 will continuously drive the one-way valve 4 to open and close alternately, allowing the medicine to form a stable circulation between the finger cavity 21, the circulation zone 36, and the lower cavity 33, ensuring that the medicine evenly covers the inflamed area of ​​the finger joints and avoiding local medicine retention or loss.

[0059] Reference Figure 8 and Figure 9 As shown, specifically, the one-way valve 4 includes a connecting frame 41 that passes through the enclosure 35. A stop block 42 is slidably disposed inside the connecting frame 41. A return spring 43 is disposed between one side of the stop block 42 and the connecting frame 41. The return spring 43 is always in a pre-tightened state, applying a continuous pushing force to the stop block 42, so that the stop block 42 fits tightly against the inner wall of the connecting frame 41, completely blocking the outlet 44 on the connecting frame 41. At this time, the one-way valve 4 is in a closed state, blocking the reverse flow of the medicine.

[0060] The connecting frame 41 is provided with a water outlet 44. When the circulation zone 36 is squeezed by the elastic film 37 or when a hand movement generates positive pressure (or negative pressure is formed on the other side), the liquid pressure is greater than the preload of the return spring 43, which will push the stop block 42 to slide towards the spring side and compress the return spring 43. As the stop block 42 moves, the water outlet 44 is opened, and the liquid flows smoothly through the water outlet 44 in a preset direction (such as from the circulation zone 36 to the fingers, or from the circulation zone 36 to the palm side cavity 21).

[0061] When the liquid medicine attempts to flow in the reverse direction, the reverse pressure acts on the side of the stop block 42 away from the spring. Together with the preload of the return spring 43, the stop block 42 is pressed further against the inner wall of the connecting frame 41, and the outlet 44 is continuously blocked to ensure that the liquid medicine cannot flow back in reverse and to maintain the directionality of the circulation path.

[0062] When the positive pressure disappears, the reset spring 43 releases its elastic potential energy, pushing the stop block 42 back to the initial sealing position, and the outlet 44 closes again, waiting for the next positive pressure to trigger the conduction, realizing the cyclical work of pressure-driven conduction spring-driven sealing, ensuring the stable one-way circulation of the liquid medicine.

[0063] The implementation principle of this invention is as follows: Step 1: Preparation for wearing: The patient puts their hand into the glove 1, and the glove is secured by the high elastic fabric of the wrist 13 and the adjustable Velcro, ensuring that the palm 11 fits the palm, the back of the hand 12 covers the back of the hand and the metacarpophalangeal joints, and the open design of the fingertips does not affect finger movement.

[0064] Step 3: Medication Injection: Inject an appropriate amount of therapeutic medication (such as concentrated anti-inflammatory and analgesic Chinese medicine) into the cavity 21 of the glove 1 through the medical-grade silicone press-type water injection valve 24 on the back of the hand 12. Control the injection volume according to the needs to preset the initial pressure. After injection, close the water injection valve 24 to ensure a seal.

[0065] Step 3: Turn on the heater 14 on the back of the hand 12 and adjust the temperature to the optimal penetration level. The outer layer 22 insulation material and the heater 14 form a double temperature lock. If you need to increase the pressure, press the air valve 26 on the outside of the wrist 13 to inflate the air bladder 25 in the cavity 21 of the wrist 13, squeeze the medicine to flow to the treatment area of ​​the hand and adjust the pressure of the cavity 21 to the appropriate level.

[0066] Step 4: Drug circulation: When the patient performs hand activities (such as stretching or clenching a fist), the elastic membrane 37 of the circulation zone 36 on the back of the hand 12 deforms with the skin's stretching and contraction. When stretching, the elastic membrane 37 expands and creates negative pressure, triggering the opening of the one-way valve 4 on the barrier 35 corresponding to the finger, pulling the drug from the finger back to the circulation zone 36; when clenching a fist, the elastic membrane 37 squeezes the circulation zone 36, increasing the pressure, closing the one-way valve 4 on the finger and opening the one-way valve 4 connected to the lower cavity 33 on the palm side, pushing the drug into the lower cavity 33. Repeated activities achieve stable circulation of the drug between the finger, circulation zone 36, lower cavity 33, and wrist cavity 21.

[0067] Step 5: Pressure Adjustment: When the hand moves, the through hole 34 of the diaphragm 31 inside the cavity 21 obstructs the rapid flow of the liquid medicine. Combined with the pressure of the air bag 25 and the squeezing of the hand muscles, the liquid pressure inside the cavity 21 is dynamically adjusted to achieve adaptive adjustment from mild pressure (daily operation) to moderate pressure (pain intensification). If the pressure is too high, press the pressure relief button on the air valve 26 to release the air in the air bag 25 and quickly reduce the pressure.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
