Description

Technical Field

[0001] This invention relates to the field of nursing devices, and more particularly to a joint pain relief device based on drug injection. Background Technology

[0002] Some patients may experience joint pain after medication injection due to the effects of the medication. In such cases, some related joint pain relief devices can be used to alleviate the patient's joint pain.

[0003] Existing technology data shows that joint pain can be relieved by promoting blood circulation through foot soaking. However, existing foot bath tubs or foot bath basins, even if they have massage functions, often only massage the soles of the feet and are unlikely to move the painful joints, so the effect of relieving foot joint pain is relatively limited. Therefore, we are now developing a joint pain relief device based on drug injection that can move the joints. Summary of the Invention

[0004] In order to overcome the shortcomings of existing joint pain relief devices that make it difficult to move painful joints, resulting in poor joint pain relief effects, the present invention provides a drug injection-based joint pain relief device that can move joints.

[0005] The technical solution is as follows: A joint pain relief device based on drug injection includes a foot bath tub with symmetrically distributed insertion holes, symmetrically distributed support legs fixed to the foot bath tub, a water outlet at the top of the foot bath tub, and a servo motor fixed to the foot bath tub. The servo motor is also fixed to a swing plate, which is rotatably connected to the foot bath tub. A rotating component is rotatably connected to the swing plate, and symmetrically distributed threaded sleeves are fixed to the rotating component. A first limiting component is threadedly connected to the threaded sleeves, and the first limiting component is slidably connected to the swing plate. A rubber pad is fixed to the first limiting component. The rotating component is equipped with a rotating assembly for driving the rotating component to rotate.

[0006] Furthermore, the rotating assembly includes a gear, which is fixedly connected to the rotating part, and a rack is fixedly connected to the side of the foot bath tub near the gear, with the rack meshing with the gear.

[0007] Furthermore, it also includes a massage mechanism, which is disposed on the first limiting member. The massage mechanism is used to massage the painful area. The massage mechanism includes movable members, the number of which is equal to the number of the first limiting member. The movable members are respectively fixed to the first limiting member. A support plate is slidably connected to the side of the swing plate near the first limiting member. The support plate is fixedly connected to symmetrically distributed connecting frames. A guide member is fixedly connected to the side of the connecting frames near the first limiting member. The guide member is slidably connected to the adjacent movable member. A rubber massage member is fixedly connected to the side of the support plate near the swing plate. A first spring is symmetrically distributed between the support plate and the swing plate.

[0008] Furthermore, it also includes a stabilizing mechanism, which is disposed in the foot bath tub and is used to stabilize the foot bath tub. The stabilizing mechanism includes a screw, which is fixed to a swing plate. An extrusion component is threadedly connected to the screw. The extrusion component is provided with an inclined surface. The extrusion component is slidably connected to the foot bath tub. The foot bath tub is fixedly connected to symmetrically distributed first air cylinders. The first air cylinders are slidably connected to first piston rods. A connecting rod is connected between the first piston rods. An extrusion rod is fixedly connected to the first piston rod near the extrusion component. The extrusion rod is extruded and engaged with the inclined surface on the extrusion component. The first air cylinders are connected to a suction cup. A limit component is provided on the first piston rod to limit the position of the first piston rod.

[0009] Furthermore, the limiting assembly includes a second limiting member, the number of which is equal to the number of the first piston rods. The second limiting members are rotatably connected to the first piston rods. A first torsion spring is wound between the second limiting member and the adjacent first piston rod. A stop member is fixedly connected to the first air cylinder, and the stop member is slidably connected to the adjacent second limiting member.

[0010] Furthermore, it also includes a mixing mechanism, which is installed in the foot bath tub. The mixing mechanism is used to add Chinese herbal medicine powder and to evenly mix the Chinese herbal medicine powder in water. The mixing mechanism includes a material box, which is fixed to the foot bath tub. A baffle plate is slidably connected to the material box. A second spring is connected between the baffle plate and the material box. A wedge block is fixed to the baffle plate. A push rod is fixed to the connecting rod. The push rod is slidably connected to the foot bath tub. The push rod and the wedge block are in a pressing fit. A swing plate is fixed with symmetrically distributed pull ropes. The other end of the pull rope is fixed to a mixing plate. The mixing plate is slidably connected to the foot bath tub. A third spring is connected between the mixing plate and the foot bath tub.

[0011] Furthermore, it also includes a sealing mechanism, which is disposed in the foot bath tub and is used to maintain the temperature inside the foot bath tub. The sealing mechanism includes a toggle member, which is rotatably connected to the side of the foot bath tub near the extruder. The toggle member and the extruder are in a pressing fit. A second torsion spring is wound between the toggle member and the foot bath tub. A second air cylinder is fixedly connected to the side of the foot bath tub near the insertion hole. The second air cylinder is slidably connected to a second piston rod, which is in a pressing fit with the toggle member. The second air cylinder is connected to an air guide tube. The foot bath tub is provided with symmetrically distributed air bladders, which surround the edges of adjacent insertion holes. The air bladders are connected to the air guide tube. The foot bath tub is provided with a locking component, which is used to lock the position of the second piston rod.

[0012] Furthermore, the locking assembly includes a fixing member, which is disposed in the foot bath tub. A pin is slidably connected to the fixing member. A fourth spring is wound between the pin and the fixing member. A perforated plate is provided on the upper part of the second piston rod. The perforated plate is pressed and engaged with the pin, and the perforated plate is inserted and engaged with the pin.

[0013] Furthermore, it also includes a wiping mechanism, which is installed in the foot bath tub. The wiping mechanism is used to initially wipe the water off the feet. The wiping mechanism includes a stabilizing component, which is symmetrically and slidably connected to the side of the foot bath tub near the insertion hole. A fifth spring connects the stabilizing component and the foot bath tub. An elastic connector is fixed to the side of the stabilizing component near the insertion hole, and a cotton cloth is fixed to the elastic connector.

[0014] Furthermore, it also includes a dryer, which is fixed to the foot bath tub.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention drives the patient's knee joint to move by reciprocating rotation of the swing plate, and drives the patient's foot joint to move by the first limiting member and the rubber pad, so that when soaking the feet, it can not only promote blood circulation, but also relieve the patient's joint pain more effectively by moving the joints.

[0016] 2. The present invention uses a moving part to compress the guide part, so that the connecting frame, support plate and rubber massage part can move up and down under the action of the first spring, thereby allowing the rubber massage part to further massage the area around the patient's foot joints, thus more effectively relieving the patient's joint pain.

[0017] 3. The present invention uses the rotation of the screw to cause the extrusion component to move the extrusion rod upward, thereby causing the first piston rod to move upward and the suction cup to be firmly attached to the ground, thus further fixing the foot bath bucket and preventing it from shaking during use, which helps patients relieve joint pain.

[0018] 4. This invention uses an automatic movement of a baffle plate to quantitatively add the powdered Chinese medicinal herbs from the filling box into the foot bath tub. In addition, the back-and-forth movement of the mixing plate ensures that the powdered Chinese medicinal herbs are evenly mixed in the hot water, which helps to further relieve joint pain in patients.

[0019] 5. This invention uses an inflatable bladder to fill the gap between the patient's leg and the insertion hole in the foot bath tub, thereby slowing down the rate at which the temperature inside the foot bath tub drops, which helps relieve the patient's joint pain.

[0020] 6. This invention uses a cotton cloth to initially dry the patient's feet, preventing water from accumulating on the surrounding ground while the patient's feet are being dried, thus eliminating the need for subsequent cleaning and making it convenient to use. Attached Figure Description

Detailed Implementation

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0040] Example 1: A joint pain relief device based on drug injection, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a foot bath tub 1, with insertion holes on both the upper rear left and right sides. Support legs 11 are symmetrically fixed to the lower left and right sides of the foot bath tub 1. A water outlet 12 is provided at the upper part of the foot bath tub 1, and a water outlet 13 is provided at the middle position of the lower part of the foot bath tub 1. The device also includes a servo motor 2, which is fixed to the upper left part of the foot bath tub 1. A swing plate 21 is fixed to the right side of the output shaft of the servo motor 2. The swing plate 21 is rotatably connected to the foot bath tub 1. A rotating component 24 is rotatably connected to the lower front part of the swing plate 21. Threaded sleeves 25 are fixed to both the left and right sides of the rotating component 24. First limiting members 26 are threadedly connected to the threaded sleeves 25. The first limiting members 26 are slidably connected to the swing plate 21. Rubber pads 27 are fixed to the first limiting members 26. A rotating assembly is provided on the left side of the rotating component 24. The rotating assembly is used to drive the rotating component 24 to rotate.

[0041] like Figure 4 As shown, the rotating assembly includes a gear 23, which is fixed to the left side of the rotating part 24. A rack 22 is fixed to the inner left side of the foot bath tub 1, and the rack 22 meshes with the gear 23.

[0042] This device is used to relieve joint pain caused by medication after a patient has received an injection. To use it, first open the inlet 12 to pour hot water at a suitable temperature into the foot bath tub 1. Note that the hot water should not exceed half the height of the tub. Then close the inlet 12. The patient can then sit in a chair and insert both feet into the two insertion holes, with the soles of their feet facing forward and downward. This allows their feet to rest on the grooves of the two first limiting members 26, which are equipped with rubber soft... The pad 27 is designed so as not to abrade the patient's skin. At this point, the servo motor 2 can be activated. Driven by the output shaft of the servo motor 2, the swing plate 21 begins to rotate alternately in both directions. This causes the patient's lower leg to swing, relieving knee pain. Driven by the swing plate 21, the rotating component 24, threaded sleeve 25, first limiting component 26, rubber pad 27, and gear 23 all rotate significantly. At this time, the gear 23, under the action of the rack 22, will also rotate at its own speed... The body rotates around its center of rotation. Because gear 23 rotates alternately in both directions, it drives rotating component 24 and threaded sleeve 25 to rotate alternately in both directions. Driven by threaded sleeve 25, the two first limiting components 26 first approach each other and then move away from each other, repeating this process continuously. Correspondingly, rubber pad 27 also moves. Driven by the first limiting components 26 and rubber pad 27, the patient's foot will swing accordingly. By keeping the lower leg still, the foot joints can be moved, relieving foot joint pain. After soaking the feet for a certain period of time, the servo motor 2 can be turned off. The patient can then pull their legs out of the foot bath tub 1, dry their feet, and place the external receiving device directly below the water outlet 13. The water outlet 13 can be opened to release the water from the foot bath tub 1, and then the water outlet 13 can be closed. The swing plate 21 drives the patient's lower legs to swing, which moves the patient's knee joints and relieves the pain in the patient's knee joints. In addition, the first limiting member 26 and the rubber pad 27 drive the movement of the patient's foot joints, which relieves the pain in the patient's foot joints and can more effectively alleviate the patient's joint pain.

[0043] Example 2: Based on Example 1, such as Figure 6 , Figure 7 and Figure 8As shown, the joint pain relief device based on drug injection also includes a massage mechanism. The massage mechanism is disposed on the first limiting member 26 and is used to massage the painful area. The massage mechanism includes two moving members 3. The two moving members 3 are respectively fixed to the front of the two first limiting members 26. A support plate 33 is slidably connected between the left and right sides of the swing plate 21. A connecting frame 32 is fixedly connected to the left and right sides of the front of the support plate 33. A guide member 31 is fixedly connected to the front of the connecting frame 32. The guide member 31 is slidably connected to the adjacent moving member 3. A rubber massage member 34 is fixedly connected to the lower part of the support plate 33. A first spring 35 is wound between the left and right sides of the support plate 33 and the swing plate 21.

[0044] To more effectively relieve joint pain, the patient's joints can be massaged. When the first limiting member 26 moves, the moving member 3 also moves back and forth under the action of the first limiting member 26. At this time, the moving member 3 will squeeze the guide member 31, causing the guide member 31 to move downward first. Under the action of the guide member 31, the support plate 33 and the rubber massage member 34 move downward, and the first spring 35 is compressed. At this time, the rubber massage member 34 will press on the area near the patient's foot joint. Then, as the first limiting member 26 continues to move, the guide member 31 is released. Then, under the action of the first spring 35, the support plate 33 and the rubber massage member 34 move upward and reset. As the first limiting member 26 continues to move back and forth, the above process is repeated. In this way, the area near the patient's foot joint can be intermittently pressed as the first limiting member 26 moves, thereby achieving massage on the area near the patient's foot joint and more effectively relieving the patient's joint pain.

[0045] like Figure 9 and Figure 10 As shown, the joint pain relief device based on drug injection also includes a stabilizing mechanism. The stabilizing mechanism is set on the foot bath tub 1 and is used to stabilize the foot bath tub 1. The stabilizing mechanism includes a screw 4, which is fixed to the right side of the swing plate 21. A pressing component 41 is threadedly connected to the screw 4. The pressing component 41 is provided with an inclined surface. The pressing component 41 is slidably connected to the foot bath tub 1. First air cylinders 45 are fixed to both the left and right sides of the foot bath tub 1. First piston rods 43 are slidably connected to the upper part of the first air cylinders 45. A connecting rod 48 is connected between the front parts of the first piston rods 43. A pressing rod 42 is fixed to the rear part of the first piston rod 43 on the right side. The pressing rod 42 is pressed and engaged with the inclined surface on the pressing component 41. Suction cups 47 are connected to the lower part of the first air cylinders 45. A limit component is provided on the first piston rod 43 to limit the position of the first piston rod 43.

[0046] like Figure 9 and Figure 10As shown, the limiting assembly includes two second limiting members 44. The two second limiting members 44 are rotatably connected to the two first piston rods 43 respectively. A first torsion spring 49 is wound between the upper part of the second limiting member 44 and the upper part of the adjacent first piston rod 43. A stop member 46 is fixedly connected to the first air cylinder 45. The stop member 46 is slidably connected to the adjacent second limiting member 44.

[0047] Because the swing plate 21 swings, the foot bath tub 1 may wobble when placed on the ground, affecting the patient's foot bath. To solve this problem, the foot bath tub 1 can be fixed to the ground by the suction cup 47, thereby increasing the stability of the foot bath tub 1. In the initial state, the first torsion spring 49 is in a torsional state, and the second limiting member 44 is limited by the blocking member 46. The second limiting member 44 cannot rotate under the action of the first torsion spring 49. When the swing plate 21 rotates, the screw 4 rotates accordingly under the drive of the swing plate 21. Driven by screw 4, extruder 41 moves to the right first. At this time, the inclined surface on extruder 41 contacts extrusion rod 42, and extrusion rod 42 moves upward under the extrusion force. Thus, first piston rod 43 and connecting rod 48 also move upward together. Driven by first piston rod 43, second limiting member 44 moves upward. When second limiting member 44 moves upward and disengages from stop member 46, second limiting member 44 rotates under the action of first torsion spring 49. At this time, stop member 46 will prevent second limiting member 44 from moving downward. Therefore, at this time, both the first piston rod 43 and the extrusion rod 42 will remain in the upper position, and the extrusion rod 42 will no longer affect the left and right movement of the extrusion component 41. Because the first piston rod 43 moves upward, the first air cylinder 45 and the suction cup 47 are in a negative pressure state. The suction cup 47 will be further tightened to the ground under the compression of the outside air, thereby stabilizing the position of the foot bath tub 1. After the foot bath is finished, the suction cup 47 needs to be released from the ground. At this time, it is necessary to first ensure that the extrusion component 41 will not block the downward movement of the extrusion rod 42, and then... Then manually rotate the second limiting member 44 to restore it to its original position. The first torsion spring 49 will then twist again. Then manually press the first piston rod 43 downward to make the second limiting member 44 snap into the stop member 46 again. At the same time, driven by the first piston rod 43, the squeezing rod 42 and the connecting rod 48 will also move and reset. The negative pressure in the first air cylinder 45 will be relieved. The suction cup 47 will be released from the ground and stabilize the position of the foot bath bucket 1 to prevent it from shaking, which will help relieve the patient's joint pain.

[0048] like Figure 11 , Figure 12 and Figure 13As shown, the joint pain relief device based on drug injection also includes a mixing mechanism. The mixing mechanism is set in the foot bath tub 1. The mixing mechanism is used to add Chinese herbal medicine powder and mix the Chinese herbal medicine powder evenly in water. The mixing mechanism includes a material box 5, which is fixed to the upper front part of the foot bath tub 1. A baffle plate 51 is slidably connected to the bottom of the material box 5. A second spring 52 is connected between the baffle plate 51 and the material box 5. A wedge block 53 is fixed to the upper rear part of the baffle plate 51. A push rod 54 is fixed to the connecting rod 48. The push rod 54 is slidably connected to the foot bath tub 1. The push rod 54 and the wedge block 53 are pressed together. Pull ropes 55 are fixed to the lower front left and right sides of the swing plate 21. A mixing plate 56 is fixed to the lower front of the pull rope 55. The mixing plate 56 is slidably connected to the foot bath tub 1. A third spring 57 is connected between the mixing plate 56 and the inner front part of the foot bath tub 1.

[0049] To further promote blood circulation in patients, some relevant Chinese herbal medicine powder can be added to the hot water. Therefore, sufficient powder can be placed in the feeding box 5 beforehand. Because the baffle plate 51 blocks the bottom of the feeding box 5, the powder will not leak downwards into the foot bath tub 1. When the connecting rod 48 moves upwards, the push rod 54 moves upwards under its influence. When the push rod 54 contacts the wedge block 53, the wedge block 53, under the pressure of the push rod 54, causes the baffle plate 51 to move backwards, stretching the second spring 52. At this point, the bottom of the feeding box 5 is no longer blocked by the baffle plate 51. Therefore, the herbal powder in the feeding box 5 falls downwards into the hot water in the foot bath tub 1. When the push rod 54 moves upwards and passes the wedge block 53, the wedge block 53 is released. Then, under the action of the second spring 52, the blocking plate 51 and the wedge block 53 move forward and reset. At this time, the blocking plate 51 blocks the lower side of the feeding box 5 again. After the patient finishes soaking their feet, as the connecting rod 48 moves downwards and resets, the push rod 54 also moves downwards. At this time, the push rod 54 will press the wedge block 53 forward, causing the wedge block 53 to drive the blocking plate 51 forward. The second spring 52 is compressed, so the blocking plate 51 will move slightly forward. When the feeding box 5 extends, the baffle plate 51 still prevents the herbal powder inside the feeding box 5 from falling out. At this time, the push rod 54 can move downward past the wedge block 53. After the push rod 54 moves downward past the wedge block 53, the wedge block 53 is released. Then, under the action of the second spring 52, the wedge block 53 and the baffle plate 51 move backward to reset. Because the time for the baffle plate 51 to move backward and then forward to reset is constant each time, the opening time of the feeding box 5 is also constant. In this way, a specified amount of herbal powder can be automatically added without the need for manual measurement, thus making it convenient to use. As the swing plate 21 rotates, the upper end of the pull rope 55 also moves accordingly. When the swing plate 21 pulls the pull rope 55 upward, the lower front end of the pull rope 55 pulls the mixing plate 56 backward, stretching the third spring 57. Then, when the swing plate 21 rotates in the opposite direction to release the pull rope 55, the mixing plate 56 moves forward to reset under the action of the third spring 57, and the pull rope 55 tightens again. This process is repeated as the swing plate 21 rotates alternately in both directions, thereby making the mixing plate 56 stir the Chinese herbal medicine powder evenly in hot water, which helps to relieve the patient's joint pain.

[0050] like Figure 14 , Figure 15 and Figure 16As shown, the joint pain relief device based on drug injection also includes a sealing mechanism. The sealing mechanism is located in the foot bath tub 1 and is used to maintain the temperature inside the foot bath tub 1. The sealing mechanism includes a toggle member 6, which is rotatably connected to the right rear part of the foot bath tub 1. The toggle member 6 is pressed and engaged with the squeezing member 41. A second torsion spring 61 is wound between the upper part of the toggle member 6 and the foot bath tub 1. A second air cylinder 66 is fixedly connected to the rear part of the foot bath tub 1. A second piston rod 62 is slidably connected to the right part of the second air cylinder 66. The second piston rod 62 is pressed and engaged with the toggle member 6. An air guide tube 67 is connected to the left part of the second air cylinder 66. Airbags 68 are provided on both the left and right sides of the upper rear part of the foot bath tub 1. The airbags 68 are respectively surrounded around the edges of the adjacent insertion holes. The airbags 68 are all connected to the air guide tube 67. A locking component is provided on the right rear part of the foot bath tub 1. The locking component is used to lock the position of the second piston rod 62.

[0051] like Figure 15 and Figure 16 As shown, the locking assembly includes a fixing member 63, which is located on the rear right side of the foot bath tub 1. A pin 64 is slidably connected to the fixing member 63. A fourth spring 65 is wound between the pin 64 and the fixing member 63. A perforated plate 69 is provided on the upper part of the second piston rod 62. The perforated plate 69 is pressed and engaged with the pin 64, and the perforated plate 69 is inserted and engaged with the pin 64.

[0052] Because the heat inside the foot bath tub 1 can easily dissipate to the outside through the insertion hole, causing the water temperature to drop and hindering the relief of joint pain, the rate of temperature reduction can be slowed by sealing the gap between the insertion hole and the patient's legs. When the squeezing member 41 moves to the right, the actuating member 6 rotates under the push of the squeezing member 41, and the second torsion spring 61 twists. At this time, the actuating member 6 pushes the second piston rod 62 to the left, and the second piston rod 62 drives the orifice plate 69 to move to the left. At the same time, the second piston rod 62 pushes the gas in the second air cylinder 66 into the foot bath tub 1. In the air delivery tube 67, gas flows into the air bag 68, causing it to inflate. Since the patient has inserted their leg into the insertion hole, the air bag 68 adheres tightly to the patient's leg, creating a seal and slowing the escape of hot air to the outside, thus slowing the cooling rate of the hot water. When the orifice plate 69 moves to contact the pin 64, the pin 64 moves forward under the pressure of the orifice plate 69, compressing the fourth spring 65. When the hole on the orifice plate 69 is aligned with the pin 64, the pin 64 is released. Under the action of spring 65, pin 64 moves backward to reset and inserts into the hole in orifice plate 69. At this time, second piston rod 62 is locked and cannot move to the right to reset. Therefore, when the squeezing member 41 releases the actuating member 6, the actuating member 6 can rotate in the opposite direction to reset under the action of second torsion spring 61. However, the actuating member 6 will not affect the second piston rod 62 again. When the patient needs to withdraw both legs, under the condition that the actuating member 6 does not jam the second piston rod 62, pin 64 can be pushed forward by hand first, and fourth spring 65 is compressed. At this time, orifice plate 69... The second piston rod 62 is released, and then the second piston rod 62 is manually moved to the right to reset. At this time, the second air cylinder 66 is in a negative pressure state, so the gas in the air bag 68 can flow back to the second air cylinder 66 through the air guide tube 67, thereby deflating the air bag 68. The patient can then pull out both feet normally. Then, the pin 64 is released, and under the action of the fourth spring 65, the pin 64 moves backward to reset, sealing the gap between the insertion hole and the patient's legs through the air bag 68, slowing down the rate of water temperature drop, which helps to relieve the patient's joint pain.

[0053] like Figure 17 As shown, the joint pain relief device based on drug injection also includes a wiping mechanism. The wiping mechanism is set in the foot bath tub 1 and is used to initially wipe the water off the feet. The wiping mechanism includes two stabilizers 7. The two stabilizers 7 are slidably connected to the upper rear left and right sides of the foot bath tub 1. A fifth spring 73 is connected between the upper front part of the stabilizer 7 and the foot bath tub 1. An elastic connector 71 is fixedly connected to the lower rear part of the stabilizer 7. A cotton cloth 72 is fixedly connected to the elastic connector 71.

[0054] like Figure 17As shown, the joint pain relief device based on drug injection also includes a dryer 74, which is fixed to the rear side of the upper inner part of the foot bath tub 1.

[0055] Because patients need to use a towel to dry their feet while soaking, which can easily leave water on the surrounding floor and require subsequent cleaning, making it inconvenient to use, the device's built-in cotton cloth 72 can be used to initially dry the feet. When the patient places their feet into the foot bath tub 1, the stabilizer 7 needs to be manually moved upwards, causing the fifth spring 73 to stretch. The elastic connector 71 and cotton cloth 72 also move upwards with the stabilizer 7, revealing the insertion hole, allowing the feet to be placed normally into the foot bath tub 1. Then, the stabilizer 7 is released, and under the action of the fifth spring 73, the elastic connector 71 and cotton cloth 72 move downwards. At this point, because of the... Because the patient's legs obstruct the flow of water, the elastic connector 71 and the cotton cloth 72 will deform to some extent. After the patient has finished soaking their feet, before removing their feet from the foot bath tub 1, the dryer 74 can be turned on first. Then, the patient's feet can be removed from the foot bath tub 1 and the dryer 74 will dry the water on the patient's legs and feet. Then, the patient's legs and feet will come into contact with the cotton cloth 72, which will absorb the water from the patient's legs and feet, thus achieving the purpose of initial drying. Then, the dryer 74 can be turned off, and the feet can be further dried. The cotton cloth 72 provided with this device can initially dry the patient's legs and feet, preventing the patient from dripping water onto the surrounding ground while wiping, thus eliminating the need for subsequent secondary cleaning and making it convenient to use.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The servo motor (2) is fixed to a swing plate (21), which is rotatably connected to the foot bath tub (1). Driven by the output shaft of the servo motor (2), the swing plate (21) drives the patient's lower leg to swing. A rotating part (24) is rotatably connected to the lower front part of the swing plate (21). Symmetrically distributed threaded sleeves (25) are fixed to both sides of the rotating part (24). A first limiting part (26) is threadedly connected to each threaded sleeve (25). The first limiting part (26) and the swing plate (21) are slidably connected. A rubber pad (27) is fixed to the first limiting part (26). The rotating part (24) is provided with a rotating assembly, which is used to drive the rotating part (24) to rotate. The rotating assembly includes a gear (23). Gear (23) is fixed to rotating part (24). A rack (22) is fixed to the side of foot bath tub (1) near gear (23). The rack (22) meshes with gear (23). Under the drive of swing plate (21), rotating part (24), threaded sleeve (25), first limiting part (26), rubber pad (27) and gear (23) all rotate significantly with swing plate (21). At this time, gear (23) rotates under the action of rack (22), driving rotating part (24) and threaded sleeve (25) to rotate alternately in the forward and reverse directions. Under the drive of threaded sleeve (25), the two first limiting parts (26) will first approach each other and then move away from each other, and the rubber pad (27) will also move. Under the drive of first limiting part (26) and rubber pad (27), the patient's foot will also swing. It also includes a massage mechanism, which is set on the first limiting member (26). The massage mechanism is used to massage the painful area. The massage mechanism includes a moving member (3). The number of moving members (3) is equal to the number of the first limiting member (26). The moving members (3) are fixed to the first limiting member (26). The swing plate (21) is slidably connected to the support plate (33) on the side near the first limiting member (26). The support plate (33) is fixedly connected to a symmetrically distributed connecting frame (32). The connecting frame (32) is fixedly connected to the guide member (31) on the side near the first limiting member (26). The guide member (31) is slidably connected to the nearby moving member (3). The support plate (33) is fixedly connected to the rubber massage member (34) on the side near the swing plate (21). The support plate (33) and the swing plate (21) are wound with a symmetrically distributed first spring (35). When the first limiting member (26) moves, the moving member (3) will also move back and forth under the action of the first limiting member (26). At this time, the moving member (3) will squeeze the guide member (31), causing the guide member (31) to move downward first. Under the action of the guide member (31), the support plate (33) and the rubber massage member (34) will move downward, and the first spring (35) will be compressed. At this time, the rubber massage member (34) will press on the patient's foot joint. Then, as the first limiting member (26) continues to move, the guide member (31) is released. Then, under the action of the first spring (35), the support plate (33) and the rubber massage member (34) move upward and reset. As the first limiting member (26) continues to move back and forth, the above process is repeated. In this way, as the first limiting member (26) moves, the patient's foot joint can be pressed intermittently, thereby realizing the massage of the patient's foot joint.

2. The joint pain relief device based on drug injection according to claim 1, characterized in that, It also includes a stabilizing mechanism, which is set on the foot bath tub (1) and is used to stabilize the foot bath tub (1). The stabilizing mechanism includes a screw (4), which is fixed to the swing plate (21). A pressing component (41) is threadedly connected to the screw (4). An inclined surface is provided on the pressing component (41). The pressing component (41) is slidably connected to the foot bath tub (1). The foot bath tub (1) is fixedly connected to a symmetrically distributed first air cylinder (45). The first air cylinder (45) is slidably connected to a first piston rod (43). A connecting rod (48) is connected between the first piston rods (43). A pressing rod (42) is fixedly connected to the first piston rod (43) on the side close to the pressing component (41). The pressing rod (42) is pressed and engaged with the inclined surface on the pressing component (41). The first air cylinder (45) is connected to a suction cup (47). A limit component is provided on the first piston rod (43). The limit component is used to limit the position of the first piston rod (43).

3. The joint pain relief device based on drug injection according to claim 2, characterized in that, The limiting assembly includes two second limiting members (44), the number of which is equal to the number of the first piston rods (43). The second limiting members (44) are rotatably connected to the first piston rods (43). A first torsion spring (49) is wound between the second limiting members (44) and the adjacent first piston rods (43). A stop member (46) is fixedly connected to the first air cylinder (45), and the stop member (46) is slidably connected to the adjacent second limiting members (44). In the initial state, the first torsion spring (49) is in a torsion state, and the second limiting member (44) is limited by the blocking member (46). The second limiting member (44) cannot rotate under the action of the first torsion spring (49). When the swing plate (21) rotates, the screw (4) rotates under the drive of the swing plate (21). Under the drive of the screw (4), the extruder (41) will move to the right first. At this time, the inclined surface on the extruder (41) will contact the extrusion rod (42). The extrusion rod (42) will move upward under the action of the extrusion force. Therefore, the first piston rod (43) and the connecting rod (48) also move upward together. Driven by the first piston rod (43), the second limiting member (44) moves upward. When the second limiting member (44) moves upward to disengage from the stop member (46), under the action of the first torsion spring (49), the second limiting member (44) rotates. At this time, the stop member (46) will block the second limiting member (44) from moving downward. Therefore, at this time, the first piston rod (43) and the extrusion rod (42) will remain in the upper position and extrude force. The rod (42) will no longer affect the left and right movement of the extrusion part (41). Because the first piston rod (43) moves upward, the first air cylinder (45) and the suction cup (47) are in a negative pressure state. The suction cup (47) will be further tightened on the ground under the pressure of the outside air, thus stabilizing the position of the foot bath tub (1). After the foot bath is finished, the suction cup (47) needs to be released from the ground. At this time, it is necessary to first ensure that the extrusion part (41) will not block the extrusion rod (42) from moving downward, and then manually rotate the second limiting part (44). This causes the second limiting member (44) to return to its original position, the first torsion spring (49) to twist again, and then the first piston rod (43) to be manually pressed down so that the second limiting member (44) can be inserted into the stop member (46) again. At the same time, under the drive of the first piston rod (43), the squeezing rod (42) and the connecting rod (48) also move and reset, the negative pressure state in the first air cylinder (45) is relieved, the suction cup (47) is released from the ground, and the position of the foot bath bucket (1) is stabilized by the suction cup (47) to prevent the foot bath bucket (1) from shaking.
