Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent hot compress device for patients with rheumatic immune disorders. Background Technology

[0002] Commonly affected areas in rheumatic and immunological patients include highly mobile joints such as the knees, elbows, wrists, and ankles, which have curved surfaces. When experiencing pain, stiffness, or local discomfort, patients often use local heat application as an adjunct to care for the affected area or as a physical therapy to promote local blood circulation and relieve discomfort. For these affected areas, current technologies typically employ structures such as hot water bottles, heating pads, electric heating patches, bandage-style heat packs, or wearable heat therapy patches, directly attaching the heating element to the surface of the affected area, or using bandages, sleeves, or elastic fabrics to secure the heat application site.

[0003] In existing technologies, such as the Knee Pad physiotherapy product that comes with the Aqua Relief System, the product covers the affected area with a knee physiotherapy pad and fixes the pad to the outside of the joint with Velcro straps. When the device is working, the main unit continuously circulates hot or cold water into the physiotherapy pad, thereby providing continuous heat or cold therapy to the affected area. Its product page shows that hot or cold water circulates in the physiotherapy pad through a tube to form continuous coverage of a specific area, and the product is suitable for physiotherapy care for chronic or acute diseases in hospital settings.

[0004] However, in actual use of the aforementioned physiotherapy products, these devices primarily rely on straps or wrapping structures to fix the physiotherapy pad to the affected area. When dealing with areas with significant curvature and high mobility, such as the knee and elbow joints, the positioning of the affected area mainly depends on manual adjustment and tightening, which can easily lead to unstable fixation or displacement of the heat application position during use. Furthermore, these devices typically require manual placement of the physiotherapy pad on the affected area before a circulation system delivers hot water into the pad for heat application. The positioning process and the heat application process are separate, making the process cumbersome and difficult to maintain a stable fit between the heat application area and the affected area throughout the heat application process. Therefore, it is necessary to propose an intelligent heat application device for rheumatic and immunological patients to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an intelligent hot compress device for rheumatic and immunological patients. The device uses a drive component to clamp and position the patient's affected area, and a liquid supply component provides heated liquid to the hot compress component during the application of the hot compress component to the affected area, thereby achieving intelligent hot compress on the patient's affected area.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An intelligent hot compress device for rheumatic immune patients includes a driving component and a fixed plate. The driving component is electrically connected to a controller. Several fixed columns are fixedly connected to the bottom of the driving component. The other ends of the fixed columns are all fixedly connected to the fixed plate. A clamping assembly for clamping the patient's affected area is provided below the fixed plate. The clamping assembly includes a threaded rod. One end of the threaded rod passes through the fixed plate and is coaxially fixedly connected to the output end of the driving component. The threaded rod is rotatably engaged with the fixed plate. A movable plate is threadedly engaged with the threaded rod. A rotating rod is symmetrically hinged to the fixed plate. A clamping arm is hinged to the other end of each rotating rod. Both ends of the movable plate are rotatably engaged with the adjacent clamping arms. An adjusting block is rotatably engaged at the end of each clamping arm away from the rotating rod. A hot compress component for providing hot compress to the affected area is provided at the end of the adjusting block away from the clamping arm. A liquid supply component for providing heating liquid to the hot compress component is provided on the movable plate.

[0007] The technical principles of the above solution are as follows: After the patient aligns the heating element with the affected area, the controller activates the drive mechanism. The drive mechanism rotates the threaded rod, which, while rotating in conjunction with the fixed plate, moves the movable plate axially along the threaded rod through its threaded engagement with the movable plate. During this movement, the movable plate, through its rotational engagement with the clamping arms and the hinged support of the rotating rod, causes the clamping arms on both sides to swing towards the affected area. This allows the heating element, located at the adjustment block, to gradually approach and clamp the patient's affected area. The liquid supply component provides heated liquid to the heating element for applying heat to the patient's affected area. The controller can also set the heating duration and stop the drive mechanism after the preset time is reached.

[0008] The above approach has the following beneficial effects: 1. The present invention drives the threaded rod to rotate through the driving component, thereby driving the moving plate to move. The moving plate, together with the rotating rod and the clamping arm, drives the hot compress component to gradually approach and clamp the patient's affected area, so that the hot compress component can stably fit the affected area during the hot compress process, thereby improving the stability of the device for the patient's affected area.

[0009] 2. The present invention provides heating liquid to the heat therapy component through the liquid supply component, so that the heat therapy component can apply heat to the patient's affected area after being applied to the affected area, thereby coordinating the clamping and positioning with the heat therapy process and improving the ease of use of the device.

[0010] 3. By setting the heat application time, the device automatically ends clamping after the preset time is reached, thus enabling better intelligent control when applying heat to the patient's affected area, reducing continuous manual operation, and improving the adaptability of the device during use.

[0011] Furthermore, the hot compress component includes several push plates, each of which is fixedly connected to an adjacent adjusting block. A second bladder is fixedly connected to the side of each push plate away from the adjusting block, and the second bladder is connected to the liquid supply component.

[0012] Beneficial effects: The second capsule can gradually move closer to the affected area as the clamping arm moves. At the same time, after the second capsule is connected to the liquid supply component, it can receive heated liquid, thereby applying heat to the side of the affected area during clamping, improving the coverage and heat application stability of the side area of ​​the affected area.

[0013] Furthermore, a turntable is coaxially rotatably fitted at the bottom of the threaded rod, and a first bladder is fixedly connected to the bottom of the turntable. The first bladder is connected to the liquid supply assembly.

[0014] Beneficial effects: The first capsule can cover the area above the affected area. During the hot compress process, it can work with the second capsule to form a coordinated hot compress coverage of the affected area from top to bottom, thereby improving the overall coverage of the affected area and enhancing the fit and uniformity of heat transfer during the hot compress.

[0015] Furthermore, the liquid supply assembly includes several water storage tanks, which are symmetrically and fixedly connected to the drive unit and the side wall of the fixed plate. Fixed blocks are symmetrically and fixedly connected to the side wall of the moving plate. A piston rod is fixedly connected to the top of each fixed block. The other end of the piston rod passes through the water storage tank and is fixedly connected to a piston plate inside the water storage tank. A heating plate is fixedly connected to the top of the piston plate. The heating plate is electrically connected to the controller. Each water storage tank has a liquid outlet hole at the top, and the liquid outlet hole communicates with the first bladder and the second bladder.

[0016] Beneficial effects: The liquid is stored in the water tank, and the piston rod and piston plate cooperate with the moving plate so that the moving plate can drive the piston plate to push the liquid synchronously during the clamping process of the clamping arm. The liquid is heated by the heating plate and delivered to the first and second bladders through the liquid outlet, so that the heat therapy component can obtain the heated liquid, thereby improving the synergy and structural integration of the device in the heat therapy process.

[0017] Furthermore, pressure sensors are provided in the first capsule and several second capsules, and the pressure sensors are all electrically connected to the controller.

[0018] Beneficial effects: By setting pressure sensors in the first and second bladders, the controller can acquire the pressure signal when the heat therapy component acts on the affected area, and adjust the operating status of the drive component according to the pressure change, thereby facilitating the control of the clamping force, making the device adapt to the pressure requirements of different affected areas, and improving the intelligent adjustment capability and user comfort during the heat therapy process.

[0019] Furthermore, a damping positioning structure is provided at the rotational engagement point between the adjusting block and the clamping arm.

[0020] Beneficial effects: The damping positioning structure allows the adjustment block to remain relatively stable after rotation and adjustment, preventing the second bladder from shaking randomly during use. It also makes it easy to adjust the angle of the second bladder according to the shape of the affected area, thereby improving the fit between the second bladder and the side of the affected area and the stability of the hot compress position.

[0021] Furthermore, a shell is fixedly connected to the side wall of the water storage tank.

[0022] Beneficial effects: The shell can further secure the water tank and drive components, and can also provide some protection and shielding for the internal structure of the device, reducing the impact of external collisions on the water tank and its connecting structure, thereby improving the overall structural regularity and stability of the device during use.

[0023] Furthermore, the bottom of the first capsule is designed as an inwardly concave arc surface.

[0024] Beneficial effects: By setting the bottom of the first bladder to be concave inward, the first bladder can better fit the surface of the affected area when it comes into contact with the upper part of the affected area, such as the knee. This improves the degree of coverage of the upper part of the affected area by the first bladder, allowing the heat to be applied to the affected area more evenly, and improving the fit and stability of the heat application process.

[0025] Furthermore, the push plate can be either a straight plate or an arc-shaped plate. When the push plate is an arc-shaped plate, the cross-section of the second bladder is set to an arc shape.

[0026] Beneficial effects: By selecting either a straight or curved push plate, the device can choose the appropriate support form according to the shape of different affected areas. When a curved push plate is selected, the cross-section of the second bladder is set to be curved, so that when the second bladder is attached to the side of the affected area, it is more adaptable to the outer contour of the leg or joint, improving the fit and heat compatibility during lateral wrapping.

[0027] Furthermore, temperature sensors are installed in both the second and first capsules.

[0028] Beneficial effects: The controller can obtain temperature signals of the corresponding areas of the first and second capsules through temperature sensors, and adjust the operation of the device accordingly, thereby facilitating the monitoring of the hot compress status and enabling the device to have better temperature sensing capabilities during the hot compress process, thus providing support for the realization of hot compress duration control and intelligent operation.

Therefore, they should not be construed as limitations on the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The following detailed description illustrates the specific implementation method: Example 1:

[0038] As attached Figure 2As shown: A smart hot compress device for patients with rheumatic immune disorders includes a driving component 1 and a fixing plate 3. The driving component 1 is electrically connected to a controller. Several fixing columns 2 are bolted to the bottom of the driving component 1. The other end of each fixing column 2 is bolted to the fixing plate 3. A clamping component for clamping the patient's affected area is provided below the fixing plate 3.

[0039] The clamping assembly includes a threaded rod 5, one end of which passes through the fixed plate 3 and is coaxially bolted to the output end of the drive component 1. The threaded rod 5 is rotatably engaged with the fixed plate 3, and a movable plate 4 is threadedly engaged with the threaded rod 5. A rotating rod 6 is symmetrically hinged to the fixed plate 3, and a clamping arm 7 is hinged to the other end of each rotating rod 6. Both ends of the movable plate 4 are rotatably engaged with their adjacent clamping arms 7. An adjusting block 8 is rotatably engaged at the end of each clamping arm 7 away from the rotating rod 6. A damping positioning structure is provided at the rotatable engagement point between the adjusting block 8 and the clamping arm 7. In this embodiment, the damping positioning structure uses an existing torque hinge. Its basic principle is to provide continuous resistance during rotation through internal frictional damping, so that the two relatively rotating components can remain relatively stable after being adjusted to any angle, avoiding arbitrary rotation in the non-adjusted state. This is existing technology and will not be elaborated further in this embodiment.

[0040] Specifically, the patient first places the affected area between the two clamping arms 7, and rotates the adjusting block 8 according to the shape of the affected area to a suitable angle for subsequent hot compress application. The damping positioning structure provides a certain resistance during the adjustment process, ensuring that the adjusting block 8 remains relatively stable after adjustment. Subsequently, the controller controls the drive component 1 to operate, which drives the threaded rod 5 to rotate. The threaded rod 5, through its threaded engagement with the moving plate 4, drives the moving plate 4 to move axially. During the movement, the moving plate 4 pulls the two clamping arms 7 to swing around the rotating rod 6, causing the two clamping arms 7 to gradually move closer to the affected area for clamping.

[0041] The end of the adjusting block 8 away from the clamping arm 7 is provided with a heat therapy component for providing heat to the affected area, and the movable plate 4 is provided with a liquid supply component for providing heating liquid to the heat therapy component.

[0042] like Figure 2 and Figure 3 As shown, the hot compress assembly includes several push plates 9, each of which is bolted to an adjacent adjusting block 8. A second bladder 11 is bonded to the side of each push plate 9 away from the adjusting block 8. The second bladder 11 is connected to the liquid supply assembly. A turntable 16 is coaxially rotatably fitted to the bottom of the threaded rod 5. A first bladder 10 is bonded to the bottom of the turntable 16. The first bladder 10 is connected to the liquid supply assembly.

[0043] Specifically, the first pouch 10 is initially positioned above the affected area, while the second pouches 11 are positioned on either side of the affected area. As the clamping arm 7 swings inward, the push plate 9 moves the second pouches 11 from the sides of the affected area closer to it. Simultaneously, the first pouch 10 below the turntable 16 applies pressure to the upper part of the affected area, thus creating a state where the affected area is simultaneously covered from above and to the sides. The adjusting block 8 can rotate relative to the clamping arm 7, so the application angle of the second pouch 11 can be adjusted according to the shape of the affected area. This is especially beneficial when used on curved surfaces such as the knees and elbows, making it easier to press the heat application area firmly onto the surface of the affected area and preventing any area from being suspended.

[0044] like Figure 1 and Figure 2 As shown, the liquid supply assembly includes several water storage tanks 14. The water storage tanks 14 are symmetrically bolted to the drive unit 1 and the side wall of the fixed plate 3. The side wall of the moving plate 4 is symmetrically bolted to fixed blocks 12. A piston rod 13 is bolted to the top of each fixed block 12. The other end of the piston rod 13 passes through the water storage tank 14 and is bolted to a piston plate 15 inside the water storage tank 14. A heating plate is adhered to the top of the piston plate 15 and is electrically connected to the controller. Each water storage tank 14 has a liquid outlet 17 at its top, which communicates with the first bladder 10 and the second bladder 11. Pressure sensors are installed inside the first bladder 10 and the several second bladders 11, and these pressure sensors are electrically connected to the controller. Temperature sensors are installed inside the second bladders 11 and the first bladder 10.

[0045] Specifically, the controller controls the heating plate to heat the liquid in the water tank 14. When the device clamps the affected area, the moving plate 4 moves along the threaded rod 5, and the fixed block 12 simultaneously drives the piston rod 13 and piston plate 15 to move inside the water tank 14, so that the heated liquid in the water tank 14 enters the first bladder 10 and the second bladder 11 through the liquid outlet 17, and then the first bladder 10 and the second bladder 11 apply heat to the affected area.

[0046] The pressure sensor is used to collect the pressure signal when the first capsule 10 and the second capsule 11 are attached to the affected area. The temperature sensor is used to collect the temperature signal inside the first capsule 10 and the second capsule 11. The controller presets the maximum pressure threshold and the minimum pressure threshold, as well as the maximum temperature threshold and the minimum temperature threshold. During use, the controller adjusts the working state of the drive component 1 according to the collected pressure and temperature signals. When the pressure value detected by the pressure sensor exceeds the maximum pressure threshold, the controller controls the output shaft of the drive component 1 to stop rotating to avoid over-clamping. When the pressure value is lower than the minimum pressure threshold, the controller determines that the clamping is not in place and continues to drive the clamping arm 7 to swing inward until the pressure value reaches the preset range.

[0047] When the temperature detected by the temperature sensor is lower than the minimum temperature threshold, the controller controls the heating plate to continuously heat the liquid in the water tank 14; when the temperature exceeds the maximum temperature threshold, the controller controls the heating plate to stop heating or adjusts the reverse rotation of the drive component 1 to prevent burns, so that the heat therapy temperature is always maintained within the preset safe and comfortable range.

[0048] This prevents injury to the patient from excessive clamping force or excessively high heat application temperature, while also avoiding reduced clamping and heat application effects due to insufficient clamping force or excessively low temperature. When the liquid temperature inside the first capsule 10 and the second capsule 11 becomes too low, the controller can restart the clamping and releasing cycle, allowing the affected skin to breathe briefly while replenishing the liquid and preventing prolonged pressure. Simultaneously, the controller can set the heat application duration; after the preset time is reached, it controls the drive unit 1 to stop working and release the clamp, making it more convenient to use.

[0049] In this embodiment, the clamping assembly is driven by the drive component 1 to clamp the affected area, and the liquid supply assembly and the hot compress assembly are used to wrap and apply heat to the affected area. In addition, the pressure sensor, temperature sensor and controller are used to adjust the hot compress process, thereby achieving stable adhesion, heating and hot compress and intelligent control of the affected area of ​​rheumatic immune patients.

[0050] Example 2:

[0051] As attached Figure 4 As shown, the difference from Embodiment 1 is that the side wall of the water storage tank 14 is bolted to the shell 18. The bottom of the first bladder 10 is set as an inwardly concave arc surface. The push plate 9 is selected as either a straight plate or an arc plate. In this embodiment, an arc plate is selected. When the push plate 9 is an arc plate, the cross-section of the second bladder 11 is set as arc.

[0052] Specifically, the outer shell 18, positioned on the outside of the water tank 14, provides shielding and protection for the water tank 14 and its connecting parts, resulting in a more streamlined overall device. With the bottom of the first bladder 10 featuring an inwardly concave arc surface, it is easier for the first bladder 10 to adhere to the upper surface of curved areas such as the knee when the affected area is aligned with the hot compress area, preventing the center from being blocked while the edges are suspended. In this embodiment, the push plate 9 is an arc-shaped plate, and the cross-section of the second bladder 11 is also correspondingly arc-shaped. This allows the second bladder 11 to better conform to the side of the affected area along the contour of the leg or joint when the clamping arms 7 swing inward, providing a stronger sense of envelopment on both sides of the affected area and more stable contact during hot compresses.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
