Description

Technical Field

[0001] The present invention belongs to the field of medical auxiliary equipment, and specifically relates to a relief device for preventing muscle spasms in hemodialysis patients. Background Art

[0002] Leg muscle spasm is a common complication during hemodialysis, mostly occurring in the middle and late stages of hemodialysis. The causes are related to excessive weight gain, too rapid and excessive dehydration, as well as factors such as low blood pressure, low sodium, and low calcium during dialysis. Although leg muscle spasm is a transient and non-fatal factor, it can cause local muscle tonic contraction and severe pain during an attack, making it very difficult for patients to endure and unable to continue dialysis, resulting in insufficient dialysis. Therefore, when lower limb spasm occurs, it is necessary to massage the patient's muscles to relieve the spasm pain. However, the existing spasm relief devices can only massage one or two acupoints, and the relief effect is not significant.

[0003] To solve the above problems, a patent with the Chinese patent publication number CN 216061235 U discloses a device for relieving lower limb muscle spasms in dialysis patients during hemodialysis, including an upper annular plate, a lower annular plate, a massage mechanism, and a fixing mechanism; the massage mechanism includes a fixing frame, the fixing frame is fixedly connected to the lower annular plate, a flexible belt is fixedly sleeved on the top wall of the fixing frame, a number of massage balls are fixedly placed inside the flexible belt, and a rotating motor is fixedly connected to the right side wall of the fixing frame. In this application, the rotating motor works to drive the threaded rod to rotate, the rotation of the threaded rod drives the movement of the moving sleeve, the movement of the moving sleeve drives the movement of the fixing block on the moving plate, and the fixing block pushes the passing flexible belt upward, and the massage balls move upward.

[0004] In this device, the fixing block moves to push the massage balls at different positions upward, so as to massage different positions of the lower limbs. At the same time, the heating wire inside the splint works to heat the lower limbs, making the spasm relief effect more significant. However, when the device is used, the patient's legs are fixed first and then massaged. During the massage process, the components for fixing the patient are always in contact with the patient's legs, which may cause discomfort to the patient. At the same time, in the existing devices, they are all manually turned on, and massage can be carried out after being turned on. However, the massage time, massage intensity, etc. all need to be adjusted manually, which may have disadvantages such as relying on manual operation, subjective judgment, difficulty in maintaining consistency, and not being suitable for long-term use, reducing the relief effect when preventing muscle spasms in hemodialysis patients. Therefore, this solution proposes a relief device for preventing muscle spasms in hemodialysis patients, providing a more comfortable relief experience for hemodialysis patients and preventing muscle spasms. Summary of the Invention

[0005] In order to solve the problems that the massage time, massage intensity, etc. all need to be adjusted manually, which may lead to dependence on manual operation, subjective judgment, difficulty in maintaining consistency, and unsuitability for long-term use, the present invention provides a relief device for preventing muscle spasms in hemodialysis patients, so as to provide a more comfortable relief solution and experience for hemodialysis patients and prevent muscle spasms.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A relief device for preventing muscle spasms in hemodialysis patients includes a support frame. On one side of the support frame, a display for inputting patient information is fixedly connected. The display is signal-connected to a processor, and the processor is signal-connected to a controller. The processor is used to formulate a massage plan according to the input patient information.

[0007] On both sides of the support frame, placing cylinders are fixedly connected. At the top inside the placing cylinder, a fixing member is fixedly connected. At the bottom of the placing cylinder, several driving members and massage members are provided. The driving members respectively drive the massage members to perform massage; the driving members are all connected to a transmission assembly, the transmission assembly is connected to a disc, and a first push rod and a second push rod are fixedly connected to the edge of the disc. The length of the first push rod is longer than that of the second push rod.

[0008] One side of the fixing member is connected to an adjusting plate. On the side of the adjusting plate close to the disc, a first fixing block and a second fixing block are fixedly connected. The height of the first fixing block is higher than that of the second fixing block. A sliding groove is provided in the middle of the adjusting plate. A sliding block is fixedly connected to the inner wall of the placing cylinder. The sliding block is located in the sliding groove and is slidably matched with the sliding groove. One end of an L-shaped operating rod is rotatably connected to the inner wall of the placing cylinder on one side of the adjusting plate, and a clamping block is fixedly connected to one end of the operating rod; when the disc rotates, the first push rod can push the first fixing block to raise the height of the adjusting plate. At this time, the clamping block is engaged with the second fixing block to fix the height of the adjusting plate; when the disc continues to rotate, the second push rod pushes the operating rod to disengage the first clamping block from the second fixing block, and at this time the height of the adjusting plate decreases.

[0009] Principle and beneficial effects of adopting the above scheme: Before using the device, use the display to input the patient's identity information and case information, from which the required hemodialysis time can be obtained. According to the patient's hemodialysis time and the patient's information, the processor can formulate a corresponding massage plan. According to the patient's identity information and case information, a corresponding massage plan is formulated under the control of the processor to provide personalized massage services for each patient. When using the device, place the support frame and the placing cylinder on the bed or beside the patient's leg, put the patient's leg into the placing cylinder, use the fixing member to limit the patient's leg to a certain extent, and use the display screen and the controller to control the driving member to operate.

[0010] When the driving member operates, it drives the massage member to massage the patient's leg. By massaging the leg, it can relieve the muscle spasm that may occur during hemodialysis and improve the patient's comfort. At this time, the driving member drives the disc to rotate through the transmission assembly. When the disc rotates, the first push rod can push the first fixed block to raise the height of the adjusting plate. At this time, the clamping block is engaged with the second fixed block to fix the height of the adjusting plate. When the disc continues to rotate, the second push rod pushes the operating rod to disengage the first clamping block from the second fixed block, and at this time the height of the adjusting plate decreases.

[0011] Since the adjusting plate is fixedly connected to the fixing member, when the height of the adjusting plate increases or decreases, it drives the fixing member to increase or decrease. Thus, the fixing member is intermittently lifted to limit the patient's leg through the fixing member, which not only ensures the patient's safety but also avoids discomfort caused to the patient by long-term contact with the fixing member. By intermittently lifting the fixing member with the adjusting plate, it avoids the discomfort caused by long-term fixation to the patient, provides a more comfortable relief experience for hemodialysis patients, and prevents muscle spasm.

[0012] Furthermore, the massage member includes a Y-shaped connecting rod, a first rod and a second rod rotatably connected to the support frame. The first rod and the second rod are respectively rotatably connected to both ends of the connecting rod. A connecting block is rotatably connected to the end of the connecting rod away from the first rod and the second rod. An auxiliary rod is fixedly connected between the connecting rods of adjacent massage members. A through groove is provided at the bottom of the placing cylinder. The auxiliary rod is in clearance fit with the through groove. A plurality of massage balls are fixedly connected to the top of the auxiliary rod. One end of the first rod is fixedly connected to the output shaft of the driving member.

[0013] Beneficial effects: Due to the design of the connecting rod, the support frame and the auxiliary rod, the device can achieve a variety of massage methods and techniques, providing a comprehensive and detailed massage experience. The driving member in the device can provide power, enabling the massage member to continuously operate automatically without manual operation by the user, and having a certain control over the massage strength and frequency. The auxiliary rod between adjacent massage members cooperates with the through groove and the massage balls to ensure uniform distribution and transmission of the massage force, enhancing the massage effect.

[0014] Furthermore, the transmission assembly includes a first bevel gear coaxially and fixedly connected to the output shaft of the driving member. The first bevel gear meshes with a second bevel gear. A transmission rod passes through the middle of the second bevel gear, and the transmission rod is fixedly connected to the second bevel gear. Both ends of the transmission rod are rotatably connected to the placing cylinder. A third bevel gear is coaxially and fixedly connected to the end of the transmission rod away from the first bevel gear. The third bevel gear meshes with a fourth bevel gear. The fourth bevel gear is rotatably connected to the placing cylinder. The disc is coaxially and fixedly connected to the fourth bevel gear.

[0015] Beneficial effects: Through the meshing transmission of the first bevel gear and the second bevel gear, effective speed conversion and transmission are achieved, improving the transmission efficiency of the entire massage device. The transmission rod is fixedly connected to the second bevel gear and the placement cylinder, transmitting force more stably and reliably, reducing vibration and sway during operation, and enhancing the stability of the massage device. Through the meshing transmission of the third bevel gear and the fourth bevel gear, speed selection and adjustment of different gears can be achieved to meet the massage needs of different users.

[0016] Furthermore, the fixing member includes an arc-shaped pressing plate and several first springs. The top ends of the first springs are fixedly connected to the inner top wall of the placement cylinder, the bottom ends of the first springs are fixedly connected to the pressing plate, and the adjusting plate is fixedly connected to one side of the pressing plate.

[0017] Beneficial effects: The arc-shaped pressing plate can provide uniform supporting force, enabling the massage device to be fixed on the placement cylinder more stably, reducing shaking and instability during operation. By using several first springs, elastic adjustment of the massage device can be achieved. The elastic characteristics of the springs can be adjusted according to the needs of users, providing appropriate elastic support and massage effect.

[0018] Furthermore, clamping members are provided on both sides inside the placement cylinder. The clamping members include several second springs fixedly connected to the inner wall of the placement cylinder, and an arc-shaped limiting plate is fixedly connected to the end of the second spring away from the placement cylinder.

[0019] Beneficial effects: The arc-shaped limiting plate can facilitate the limitation of the left and right sides of the patient's leg, and at the same time, the second spring can facilitate the automatic adjustment of the position of the limiting plate to be suitable for patients with different leg circumferences.

[0020] Furthermore, sponge layers are fixedly connected to the concave surfaces of the pressing plate and the limiting plate.

[0021] Beneficial effects: The sponge layer can provide a soft and elastic texture, providing a more comfortable massage experience for users. The sponge material can buffer pressure and reduce hard contact, alleviating irritation to the skin. The sponge layer has good shock absorption performance, which can reduce the pressure and vibration from the pressing plate or the limiting plate during massage, making the massage process more comfortable and stable. The sponge material usually has good moisture absorption and breathability performance, which can quickly absorb sweat and discharge hot air, maintaining a dry and breathable massage environment. As a soft material, the sponge layer can effectively protect the skin from direct contact friction and irritation, reducing the risk of potential skin damage.

[0022] Furthermore, a housing is fixedly connected to the outside of the support frame. There are several ventilation openings on the housing, and several fan blades are fixedly connected to the connecting rod.

[0023] Beneficial effects: The ventilation openings on the housing can promote air flow, increase the heat dissipation area, help dissipate the heat generated by the device, thereby effectively reducing the temperature and keeping the device within the normal operating temperature range. The ventilation openings enable the surrounding air to enter the interior of the housing, come into contact with the surface of the device, and carry away the heat. This can reduce the operating temperature of the device and improve the stability and lifespan of the device. The fan blades on the connecting rod can generate air flow through the movement of the connecting rod, increasing the cooling effect of the air on the heat dissipation device. The continuous movement of the fan blades can improve the heat transfer rate, accelerate heat transmission, and further improve the heat dissipation efficiency.

[0024] Furthermore, several telescopic rods are fixedly connected to the bottom of the housing. The telescopic rods include fixed tubes and movable tubes. The top of the fixed tube is fixedly connected to the bottom of the housing. The movable tube is located inside the fixed tube and is slidably matched with the fixed tube. Screws are threadedly engaged with the movable tubes, and several threaded holes are provided on the fixed tubes.

[0025] Beneficial effects: Through the design of the telescopic rods, by means of the movable tube sliding inside the fixed tube, the height of the entire structure can be adjusted. By adjusting the length of the telescopic rods, the support frame can adapt to the requirements of different heights or positions. The telescopic rods adopt a structure in which the fixed tube and the movable tube cooperate with each other and are fixed to the bottom of the housing. This design can provide better stability and support force, enabling the connected structure to be firmly fixed in the required position and remain stable. Description of the Drawings

[0030] Embodiment 1

[0031] The embodiments are basically as shown in the appended Figure 1 and the appended Figure 2 as follows:

[0032] A relief device for preventing muscle spasms in hemodialysis patients, comprising a support frame 1, on one side of the support frame 1 is fixedly connected with a display 2 for inputting patient information, and the model of the display 2 is preferably CX530H; the display 2 is signal-connected to a processor, the processor is signal-connected to a controller, and the model of the controller is preferably AQMD6020BLS-EX; the processor is used to formulate a massage plan according to the input patient information.

[0033] On both sides of the support frame 1 are fixedly connected with placing cylinders 3. At the inner top of the placing cylinder 3 is fixedly connected with a fixing member 4. At the bottom of the placing cylinder 3 are provided a number of driving members 5 and massage members 6. The driving member 5 is a motor, and its model is preferably 5IK120RGU-CF. The driving members 5 respectively drive the massage members 6 to perform massage; the driving members 5 are all connected with a transmission assembly 7, the transmission assembly 7 is connected with a disc 8, and fixedly connected to the edge of the disc 8 are a first push rod 9 and a second push rod 10, and the length of the first push rod 9 is longer than that of the second push rod 10.

[0034] One side of the fixing member 4 is connected with an adjusting plate 11. Close to the disc 8 on one side of the adjusting plate 11 are fixedly connected with a first fixing block 12 and a second fixing block 13 by screws. The height of the first fixing block 12 is higher than that of the second fixing block 13. A sliding groove 14 is opened in the middle of the adjusting plate 11. Inside the placing cylinder 3 is fixedly connected with a slider 15 by screws. The slider 15 is located in the sliding groove 14 and is in sliding fit with the sliding groove 14. On the inner wall of the placing cylinder 3 on one side of the adjusting plate 11 is rotatably connected with an L-shaped operating rod 16. One end of the operating rod 16 is fixedly connected with a clamping block 17 by screws; when the disc 8 rotates, the first push rod 9 can push the first fixing block 12 to raise the height of the adjusting plate 11. At this time, the clamping block 17 is engaged with the second fixing block 13 to fix the height of the adjusting plate 11; when the disc 8 continues to rotate, the second push rod 10 pushes the operating rod 16 to make the first clamping block 17 disengage from the second fixing block 13. At this time, the height of the adjusting plate 11 is lowered.

[0035] The specific implementation process is as follows: Before using the device, use the display 2 to input the patient's identity information and case information. The identity information includes, for example, name, age, height, and weight, etc. The case information includes, for example, medical history, the required course and time of hemodialysis, etc. Thus, the time required for hemodialysis can be obtained. According to the patient's hemodialysis time and the patient's information, the processor can formulate a corresponding massage plan. For example, if the patient needs 4 hours of hemodialysis, the massage time can be divided into four stages. The first stage (0 - 1 hour): In the first hour after the start of dialysis, perform gentle initial massage for forty minutes and rest for twenty minutes. This helps to relax the muscles and reduce the risk of cramps by promoting blood circulation. The second stage (1 - 2 hours): When dialysis reaches the second hour, massage for forty minutes and rest for twenty minutes, and continue with moderate massage. According to the patient's reaction and needs, the massage intensity can be appropriately increased. The third stage (2 - 3 hours): When dialysis reaches the third hour, massage for forty minutes and rest for twenty minutes, and strengthen the massage intensity. Deeper massage techniques such as kneading or squeezing can be used to relieve muscle tension and cramps. The fourth stage (3 - 4 hours): Continue to massage in the last hour, massage for forty minutes and rest for twenty minutes, focusing on dredging lymphatic detoxification, relieving stress, and enhancing the sense of relaxation. Thermotherapy can be used to increase comfort.

[0036] When using the device, place the support frame 1 and the placement cylinder 3 on the bed or beside the patient's leg. Let the patient put the leg into the placement cylinder 3, and use the fixing member 4 to limit the patient's leg to a certain extent. Use the display screen and the controller to control the operation of the driving member 5.

[0037] When the driving member 5 operates, it drives the massage member 6 to massage the patient's leg. By massaging the leg, it can relieve the muscle cramps that may occur during hemodialysis and improve the patient's comfort. At this time, the driving member 5 drives the disc 8 to rotate through the transmission component. When the disc 8 rotates, the first push rod 9 can push the first fixing block 12 to raise the height of the adjusting plate 11. At this time, the clamping block 17 is engaged with the second fixing block 13 to fix the height of the adjusting plate 11. When the disc 8 continues to rotate, the second push rod 10 pushes the operating rod 16 to disengage the first clamping block 17 from the second fixing block 13. At this time, the height of the adjusting plate 11 decreases. When the height of the adjusting plate 11 rises or falls, it drives the fixing member 4 to rise or fall, thereby intermittently lifting the fixing member 4. By using the fixing member 4 to limit the patient's leg, it not only ensures the patient's safety but also avoids discomfort caused to the patient by long-term contact with the fixing member 4. Using the adjusting plate 11 to intermittently lift the fixing member 4 can avoid discomfort caused by long-term fixation to the patient, provide a more comfortable relief experience for hemodialysis patients, and prevent muscle cramps.
