Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a rehabilitation aid for training elderly people with mild cognitive impairment. Background Technology

[0002] Cognitive impairment, also known as cognitive deficit, is a pathological process in which abnormalities occur in the higher cognitive processes of the brain related to learning, memory, and judgment, leading to learning and memory disorders, often accompanied by aphasia, apraxia, and agnosia. It can be caused by a variety of factors, including head trauma, cerebrovascular disease, brain aging, chronic systemic diseases, environmental factors, and psychological abnormalities. Different types of cognitive impairment are interconnected and influence each other, making both diagnosis and treatment challenging.

[0003] For example, geometrically shaped plates in existing technologies, such as Figure 1 As shown, the fit between the plate and the groove is completed by placing the corresponding geometric plate into the geometric groove.

[0004] However, there are still some shortcomings in the existing technology when using geometrically shaped plates:

[0005] 1. The existing technology, which uses the combination of geometric plates and geometric grooves, is too simple and cannot provide effective rehabilitation training for mild cognitive impairment.

[0006] 2. Existing technologies simply use geometric plates and grooves to work together, resulting in limited functionality. Prolonged use can easily lead to patient boredom and habitual thinking, failing to fully arouse the patient's interest.

[0007] To address the aforementioned problems, this invention proposes a rehabilitation aid for training elderly individuals with mild cognitive impairment. Summary of the Invention

[0008] The purpose of this invention is to address the problems of existing technologies being too simple to provide effective rehabilitation training for mild cognitive impairment, having limited functionality, and failing to fully arouse the interest of patients. Therefore, this invention proposes a rehabilitation aid for training elderly people with mild cognitive impairment.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A rehabilitation aid for training elderly people with mild cognitive impairment includes a shell and a geometric plate. A discharge box is welded to the top of the shell. The top of the shell is provided with multiple rectangular grooves, which cooperate with the geometric plate. The bottom inner wall of each of the multiple rectangular grooves is provided with multiple geometric grooves, and the shapes of the multiple geometric grooves are different. The outer wall of the geometric plate is covered with a magnet layer.

[0011] The first training structure is located on the top of the housing and is used to mate the geometric plate with the corresponding geometric groove. The first training structure includes a second metal conveyor belt located on the top of the housing. The outer wall of the second metal conveyor belt is fixed with a plurality of hemispherical protrusions by bolts.

[0012] The second training structure, set inside the shell, is used to train users' ability to understand interpersonal relationships.

[0013] A finger exercise structure, housed within the housing, is designed to improve the user's finger dexterity, and hemispherical protrusions within the first training structure drive the finger exercise structure to operate.

[0014] In one possible design, the first training structure further includes two rotating rollers rotatably connected to both the outer shell and the inside of the discharge box. The four rotating rollers are connected by a first metal conveyor belt, and the geometric plate cooperates with the first metal conveyor belt. The top inner wall of the discharge box is fixed with a slanted plate that scrapes off the geometric plate adsorbed on the surface of the first metal conveyor belt by bolts. An opening is provided on one side bottom of the discharge box, and the second metal conveyor belt is located below the opening. When the first metal conveyor belt is running, it can adsorb the geometric plate and drive the geometric plate upward. The cooperation of the two guide plates allows the first metal conveyor belt to adsorb one geometric plate at a time. The slanted plate can scrape off the geometric plate adsorbed on the first metal conveyor belt. Under the guidance of the rotating plate, the geometric plate falls through the discharge box onto the second metal conveyor belt, which also adsorbs the geometric plate. In addition, the second metal conveyor belt runs at a faster speed, so the user needs to be able to remove the geometric plate from the second metal conveyor belt with a faster hand speed, which can train the user's eyesight and hand speed.

[0015] In one possible design, the first training structure further includes multiple sealing plates slidably connected to the inner wall of the top of the housing. These sealing plates are used to seal the geometric groove within the rectangular slot. Multiple pressure sensors for detecting the pressure exerted by the geometric plate on the sealing plate are fixedly embedded in the top of each sealing plate. The pressure sensors correspond to the geometric groove. Multiple iron rings that generate magnetic attraction to the geometric plate are fixedly embedded in the top of each sealing plate, and these iron rings are located outside the pressure sensors. Multiple electric push rods are bolted to the inner wall of the top of the housing, and the output shafts of the electric push rods are fixedly connected to one side of the sealing plate. The user places the geometric board into the corresponding geometric slot in one of the rectangular slots, filling each slot one by one. If the geometric board cannot fit into a slot in the same rectangular slot, it can be placed into the next slot, and so on. When the rectangular slots are filled, the electric push rod controls the closing plate to release the closure of the multiple geometric slots, and the geometric board falls onto the receiving plate. A time limit can also be set, allowing the user to fill the multiple geometric slots a specified number of times within a given time, thus increasing the difficulty and effectively training the user.

[0016] In one possible design, the second training structure includes a sliding plate that slides through the outer shell. The top of the sliding plate has multiple placement slots. A display screen is fixed to one side of the discharge box by bolts. The bottom inner wall of the placement slot is engraved with text. When the sliding plate is pulled out of the outer shell, photos of the user's relatives and friends can be displayed on the display screen. The bottom inner wall of the placement slot is engraved with text such as parents, spouse, children, friends, brothers, and colleagues. The user can place the geometric board into the corresponding placement slot according to the picture, further exercising the user's memory and logical ability.

[0017] In one possible design, the finger exercise structure includes a circular shaft fixedly connected within a housing. A holding plate for holding a geometric plate is rotatably fitted onto the outer wall of the circular shaft. A finger extension plate extending to the outer side of the housing is bolted to one side of the holding plate. A U-shaped plate is bolted to one side of the housing, positioned below the finger extension plate. Multiple push rods slide through the housing, with their tips engaging hemispherical protrusions. A retaining ring located within the housing is fixed to the outer wall of each push rod. A tension spring, fixedly connected to the top of the retaining ring, is fitted onto the outer wall of each push rod, with its tip fixedly connected to the top inner wall of the housing. A connecting rod is rotatably connected to one side of each push rod. The U-shaped plate is connected to a base, which is bolted to the top side of the holding plate. The top of the U-shaped plate is provided with a rotating hemisphere. When the second metal conveyor belt is running, the hemispherical protrusion, in conjunction with the push rod and tension spring, can drive the holding plate to rotate back and forth, moving the geometric plates piled on the holding plate toward the first metal conveyor belt. The user can place one hand on the rotating hemisphere, the outer wall of which can be wrapped with sweat-absorbing cotton. The rotating hemisphere and the sweat-absorbing cotton can absorb the sweat on the user's palm and increase the user's comfort. The fingers can rest on the finger extension plate, and when the holding plate rotates back and forth, the finger extension plate can stretch the user's fingers, which can exercise the fingers of the elderly and increase their flexibility.

[0018] In one possible design, a rotating shaft is fixedly connected inside the discharge box. A rotating plate for guiding the geometric plate is rotatably sleeved on the outer wall of the rotating shaft. Two first torsion springs are sleeved on the outer wall of the rotating shaft. The ends of the two first torsion springs that are close to each other are fixedly connected to the two sides of the rotating plate, and the ends of the two first torsion springs that are far from each other are fixedly connected to the inner walls of the two sides of the discharge box. A limiting block for limiting the rotation plate is fixedly connected inside the discharge box. When the inclined plate scrapes the geometric plate off the first metal conveyor belt, the rotating plate can guide the geometric plate so that the geometric plate falls onto the second metal conveyor belt through the opening.

[0019] In one possible design, the top of the material holding plate is fixed with two guide plates by bolts; the two guide plates cooperate to limit the geometric plate. When the geometric plate moves to one side, the two guide plates can also control the first metal conveyor belt to only pick up one geometric plate at a time, so as to avoid picking up too many geometric plates and thus increasing the difficulty of matching the geometric plate with the geometric groove.

[0020] In one possible design, a rotating shaft rotatably passes through the U-shaped plate, with its top end fixedly connected to the bottom of a rotating hemisphere. A round rod rotatably passes through one side of the outer shell, with a second bevel gear fixed to one end of the rod below the U-shaped plate. A first bevel gear meshing with the second bevel gear is fixed to the bottom end of the rotating shaft. A one-way bearing is fitted onto the outer wall of the round rod, and a pull rope is wound around its outer wall, with its top end fixedly connected to the bottom of a material-holding plate. A second torsion spring is fitted onto the outer wall of the round rod, with one end fixedly connected to the inner wall of one side of the outer shell, and the other end of the second torsion spring connected to the one-way shaft. One side of the bearing is fixedly connected; when the right end of the material holding plate rotates upward, the material holding plate can drive the one-way bearing to rotate through the pull rope. The one-way bearing and the round rod are locked. The one-way bearing drives the round rod and the second bevel gear to rotate. The second bevel gear drives the rotating hemisphere to rotate through the first bevel gear. The outer wall of the rotating hemisphere can be provided with multiple hemispherical protrusions. The rotation of the hemispherical protrusions on the outer wall can massage the user's palm and increase the user's comfort. When the material holding plate rotates in the opposite direction, the second torsion spring drives the one-way bearing to rotate in the opposite direction. The one-way bearing and the round rod are in an active state. The one-way bearing rewinds the pull rope to facilitate the next rotation of the round rod.

[0021] In one possible design, a control center is bolted to one side of the housing, and the control center is electrically connected to an electric actuator, an electromagnet, and a display screen.

[0022] In one possible design, a drinking water tank is fixed inside the outer casing, located below one side of the holding plate, and the drinking water tank is positioned above a sliding plate. A drinking pipe, penetrating the holding plate, slides through the drinking water tank. A magnetic disk is fixed to the outer wall of the drinking pipe. An electromagnet is fixed inside the outer casing via a horizontal plate, and the electromagnet is sleeved on the outer wall of the drinking pipe. The magnetic disk cooperates with the electromagnet. A cylinder is welded to the top of the outer casing, and the top end of the drinking pipe slides through the top of the outer casing and extends into the cylinder. A sealing cap for sealing the inlet of the drinking pipe is rotatably connected to the top of the cylinder. When the electromagnet is activated by the control center, a magnetic attraction is generated between the electromagnet and the magnetic disk, causing the drinking pipe to move upward and push open the sealing cap, allowing the user to drink water through the drinking pipe.

[0023] In this invention, a second metal conveyor belt is provided on the top of the outer shell, and an opening is provided on the bottom side of the discharge box, with the second metal conveyor belt located below the opening. Multiple hemispherical protrusions are fixed to the outer wall of the second metal conveyor belt by bolts. When the first metal conveyor belt is running, it can adsorb the geometric plate. The inclined plate can scrape off the geometric plate adsorbed on the first metal conveyor belt and drop it onto the second metal conveyor belt. In addition, the second metal conveyor belt runs at a relatively high speed, so the user needs to be able to remove the geometric plate from the second metal conveyor belt with a relatively fast hand speed, which can train the user's eyesight and hand speed.

[0024] In this invention, the top inner wall of the outer shell is slidably connected with multiple sealing plates, the top of the outer shell is provided with multiple rectangular grooves, and the bottom inner wall of the rectangular grooves is provided with multiple geometric grooves. The user should fill the geometric grooves in the rectangular grooves one by one using the geometric plates. When the geometric grooves are filled, the electric push rod controls the sealing plates to release the sealing of the multiple geometric grooves. The time can be set, and the user can fill the multiple geometric grooves in the rectangular grooves a certain number of times within the specified time. This can improve the difficulty level and thus effectively achieve the training effect.

[0025] In this invention, the second training structure includes a sliding plate that slides through the outer shell. The top of the sliding plate is provided with multiple placement slots. A display screen is fixed to one side of the discharge box by bolts. The bottom inner wall of the placement slot is engraved with text. The display screen shows photos of the user's relatives and friends. The bottom inner wall of the placement slot is engraved with text such as parents, spouse, children, friends, brothers, and colleagues. The user can place the geometric board taken from the second metal conveyor belt into the corresponding placement slot according to the picture, further exercising the user's memory and logical ability.

[0026] In this invention, a finger extension plate is fixed to one side of the material holding plate. Multiple push rods that cooperate with hemispherical protrusions slide through the outer shell. A fixing ring is fixed to the outer wall of each push rod. The push rod is rotatably connected to the material holding plate via a connecting rod and a base. When the second metal conveyor belt is running, the cooperation of the hemispherical protrusions, push rods, and tension springs drives the material holding plate to rotate reciprocally. A user can place their palm on the rotating hemisphere and rest their fingers on the finger extension plate. As the material holding plate rotates reciprocally, the finger extension plate helps to stretch the user's fingers, thus exercising the fingers of the elderly and increasing their dexterity.

[0027] This invention features multiple training functions that can improve a user's eyesight, hand speed, graphic recognition ability, and interpersonal relationship analysis skills. Different abilities can be used for different users, and the combination of multiple functions can increase the user's interest in training. In addition, the test of how many times multiple geometric slots in a rectangular slot are filled within a limited time can put pressure on the user and enhance the training effect.

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Example 1

[0041] Reference Figures 2-9 A rehabilitation aid for training elderly people with mild cognitive impairment, which is used in the field of medical devices, includes a shell 1 and a geometric plate. A discharge box 2 is welded to the top of the shell 1. The top of the shell 1 is provided with multiple rectangular grooves 11, and the rectangular grooves 11 cooperate with the geometric plate. The bottom inner wall of the multiple rectangular grooves 11 is provided with multiple geometric grooves 12, and the shapes of the multiple geometric grooves 12 are different. The outer wall of the geometric plate is covered with a magnet layer.

[0042] Reference Figure 3 and Figure 4The rehabilitation aid also includes a first training structure located on the top of the outer shell 1, used to mate the geometric plate with the corresponding geometric groove 12. The first training structure includes a second metal conveyor belt 10 located on the top of the outer shell 1, and the outer wall of the second metal conveyor belt 10 is fixed with multiple hemispherical protrusions 20 by bolts. The first training structure also includes two rotating rollers 3 rotatably connected to both the outer shell 1 and the discharge box 2. The four rotating rollers 3 are connected by a first metal conveyor belt 4, and the geometric plate mates with the first metal conveyor belt 4. The top inner wall of the discharge box 2 is fixed with a sloping plate 5 that scrapes off the geometric plate adsorbed on the surface of the first metal conveyor belt 4 by bolts. An opening is provided on one side bottom of the discharge box 2. The second metal conveyor belt 10 is located below the opening. When the first metal conveyor belt 4 is running, it can attract the geometric plate and move it upward. The cooperation of the two guide plates 19 allows the first metal conveyor belt 4 to attract one geometric plate at a time. The inclined plate 5 can scrape off the geometric plate attracted on the first metal conveyor belt 4. Under the guidance of the rotating plate 7, the geometric plate falls onto the second metal conveyor belt 10 through the discharge box 2. The second metal conveyor belt 10 also attracts the geometric plate. In addition, the second metal conveyor belt 10 runs at a relatively fast speed, so the user needs to be able to remove the geometric plate from the second metal conveyor belt 10 with a fast hand speed, which can train the user's eyesight and hand speed.

[0043] Reference Figure 4 A rotating shaft 6 is fixedly connected inside the discharge box 2. A rotating plate 7 for guiding the geometric plate is rotatably sleeved on the outer wall of the rotating shaft 6. Two first torsion springs 8 are sleeved on the outer wall of the rotating shaft 6. The ends of the two first torsion springs 8 that are close to each other are fixedly connected to the two sides of the rotating plate 7, and the ends of the two first torsion springs 8 that are far from each other are fixedly connected to the inner walls of the two sides of the discharge box 2. A limiting block 9 for limiting the rotation plate 7 is fixedly connected inside the discharge box 2. When the inclined plate 5 scrapes the geometric plate off the first metal conveyor belt 4, the rotating plate 7 can guide the geometric plate so that the geometric plate falls onto the second metal conveyor belt 10 through the opening.

[0044] Reference Figure 3 and Figure 6The first training structure also includes multiple sealing plates 13 slidably connected to the inner wall of the top of the outer casing 1. The sealing plates 13 are used to seal the geometric grooves 12 within the rectangular grooves 11. Multiple pressure sensors 15 for detecting the pressure of the geometric plate on the sealing plates 13 are fixedly embedded in the top of the sealing plates 13. The pressure sensors 15 correspond to the geometric grooves 12. Multiple iron rings 14 that generate magnetic attraction to the geometric plate are fixedly embedded in the top of the sealing plates 13, and the iron rings 14 are located outside the pressure sensors 15. Multiple electric push rods 16 are fixed to the inner wall of the top of the outer casing 1 by bolts, and the output shafts of the electric push rods 16 are fixedly connected to one side of the sealing plates 13. The user places the geometric plate into one of the sealing plates. The geometric slots 12 within each rectangular slot 11 should be filled one by one. If a geometric plate cannot fit into a geometric slot 12 within the same rectangular slot 11, it can be placed into the corresponding geometric slot 12 within the next rectangular slot 11, and so on. When the geometric slots 12 within the rectangular slot 11 are filled, the electric push rod 16 controls the closing plate 13 to release the closure of the multiple geometric slots 12, and the geometric plate falls onto the material receiving plate 18. In addition, a time can be set to determine how many times the user can fill the multiple geometric slots 12 within the specified time, thereby training the difficulty and achieving an effective training effect.

[0045] Reference Figure 4 The top of the material holding plate 18 is fixed with two guide plates 19 by bolts; the two guide plates 19 work together to limit the geometric plate. When the geometric plate moves to one side, the two guide plates 19 can also control the first metal conveyor belt 4 to only pick up one geometric plate at a time, so as to avoid picking up too many geometric plates and thus increasing the difficulty of the geometric plate and the geometric groove 12.

[0046] Reference Figure 3 and Figure 8 The rehabilitation aid also includes a second training structure set inside the outer shell 1, used to train the user's understanding of interpersonal relationships. The second training structure includes a sliding plate 36 that slides through the outer shell 1. The top of the sliding plate 36 is provided with multiple placement slots 37. A display screen 35 is fixed to one side of the discharge box 2 by bolts. The bottom inner wall of the placement slot 37 is engraved with text.

The bottom inner wall of the placement slot 37 is engraved with text such as parents, spouse, children, friends, brothers and colleagues. The user can place the geometric board into the corresponding placement slot 37 according to the picture, further exercising the user's memory and logical ability.

[0047] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8The rehabilitation aid also includes a finger exercise structure housed within the outer casing 1, used to exercise the user's finger dexterity. A hemispherical protrusion 20 within the first training structure drives the finger exercise structure. The finger exercise structure includes a circular shaft 17 fixedly connected within the outer casing 1. A material holding plate 18 for holding a geometric plate is rotatably fitted onto the outer wall of the circular shaft 17.

A connecting rod 24 is rotatably connected to one side of the moving rod 21, and a base 25 is rotatably connected to one side of the connecting rod 24. The base 25 is fixed to the top side of the material holding plate 18 by bolts. A rotating hemisphere 28 is provided on the top of the U-shaped plate 27. When the second metal conveyor belt 10 is running, the hemispherical protrusion 20, in cooperation with the pushing rod 21 and the tension spring 23, can drive the material holding plate 18 to rotate back and forth, which can move the geometric plates piled on the material holding plate 18 toward the first metal conveyor belt 4. The user can place one hand on the rotating hemisphere 28. The outer wall of the rotating hemisphere 28 can be wrapped with sweat-absorbing cotton. The rotating hemisphere 28 and the sweat-absorbing cotton can absorb the sweat on the user's palm and increase the user's comfort. The fingers can be placed on the finger extension plate 26. When the material holding plate 18 rotates back and forth, the finger extension plate 26 can stretch the user's fingers, which can exercise the fingers of the elderly and increase the flexibility of the fingers.

[0048] Reference Figure 3 and Figure 9A rotating shaft 29 rotatably passes through the U-shaped plate 27, and the top end of the rotating shaft 29 is fixedly connected to the bottom of the rotating hemisphere 28. A round rod 31 rotatably passes through one side of the outer shell 1. A second bevel gear 32 located below the U-shaped plate 27 is fixed to one end of the round rod 31. A first bevel gear 30 meshing with the second bevel gear 32 is fixed to the bottom end of the rotating shaft 29. A one-way bearing 33 is sleeved on the outer wall of the round rod 31. A pull rope 34 is wound around the outer wall of the one-way bearing 33, and the top end of the pull rope 34 is fixedly connected to the bottom of the material holding plate 18.

The other end of the second torsion spring 45 is fixedly connected to one side of the one-way bearing 33. When the material is held... When the right end of plate 18 rotates upward, the material holding plate 18 can drive the one-way bearing 33 to rotate via the pull rope 34. The one-way bearing 33 and the round rod 31 are locked. The one-way bearing 33 drives the round rod 31 and the second bevel gear 32 to rotate. The second bevel gear 32 drives the rotating hemisphere 28 to rotate via the first bevel gear 30. The outer wall of the rotating hemisphere 28 can be provided with multiple hemispherical protrusions. The rotation of the hemispherical protrusions on the outer wall driven by the rotating hemisphere 28 can massage the user's palm and increase the user's comfort. When the material holding plate 18 rotates in the opposite direction, the second torsion spring 45 drives the one-way bearing 33 to rotate in the opposite direction. The one-way bearing 33 and the round rod 31 are in an active state. The one-way bearing 33 rewinds the pull rope 34 again to facilitate the next rotation of the round rod 31.

[0049] Reference Figure 3 and Figure 6 The control center 38 is fixed to one side of the outer casing 1 by bolts, and the electric push rod 16 of the control center 38 and the display screen 35 are electrically connected.

[0050] Example 2

[0051] refer to Figure 10 An improvement based on Embodiment 1: A drinking water tank 39 is fixed inside the outer shell 1, located below one side of the holding plate 18, and the drinking water tank 39 is located above the sliding plate 36. A drinking pipe 40, which passes through the holding plate 18, slides through the drinking water tank 39. A magnetic disk 41 is fixed to the outer wall of the drinking pipe 40. An electromagnet 42 is fixed inside the outer shell 1 by a horizontal plate, and the electromagnet 42 is sleeved on the outer wall of the drinking pipe 40. The magnetic disk 41 cooperates with the electromagnet 42. A cylinder 43 is welded to the top of the outer shell 1, and the top end of the drinking pipe 40 slides through the top of the outer shell 1 and extends into the cylinder 43. A sealing cover 44 for sealing the liquid inlet of the drinking pipe 40 is rotatably connected to the top of the cylinder 43. The control center 38 is electrically connected to the electromagnet 42. When the control center 38 starts the electromagnet 42, a magnetic attraction force is generated between the electromagnet 42 and the magnetic disk 41, the drinking pipe 40 moves upward and pushes open the sealing cover 44, and the user can drink water through the drinking pipe 40.

[0052] A method for using a rehabilitation aid to train older adults with mild cognitive impairment includes the following steps:

[0053] S1. When training is required using the geometric plate and the geometric groove 12, the first metal conveyor belt 4 starts running. Since the surface of the geometric plate is covered with magnets, the first metal conveyor belt 4 can attract the geometric plate and move it upward. The cooperation of the two guide plates 19 allows the first metal conveyor belt 4 to attract one geometric plate at a time. The inclined plate 5 can scrape off the geometric plate attracted on the first metal conveyor belt 4. Under the guidance of the rotating plate 7, the geometric plate falls onto the second metal conveyor belt 10 through the discharge box 2. The second metal conveyor belt 10 also attracts the geometric plate. In addition, the second metal conveyor belt 10 runs at a faster speed, so the user needs to be able to remove the geometric plate from the second metal conveyor belt 10 with a faster hand speed, which can train the user's eyesight and hand speed.

[0054] S2. The user places the geometric plate into the corresponding geometric slot 12 within one of the rectangular slots 11. The geometric slots 12 within the rectangular slots 11 should be filled one by one. If the geometric plate cannot be matched with the geometric slot 12 within the same rectangular slot 11, the geometric plate can be placed into the corresponding geometric slot 12 within the next rectangular slot 11, and so on. When the geometric slots 12 within the rectangular slots 11 are filled, the signals emitted by the multiple pressure sensors 15 are received by the control center 38. The control center 38 controls the output shaft of the electric push rod 16 to extend, and the sealing plate 13 releases the sealing of the multiple geometric slots 12. At this time, the geometric plate falls onto the material holding plate 18 under the action of gravity. In addition, after the geometric plate is placed into the corresponding geometric slot 12, the pressure sensor 15 senses the pressure signal. At this time, the first metal conveyor belt 4 can run again. Therefore, only one geometric plate can be matched with the geometric slot 12 at a time. In addition, a time can be set to determine how many times the user can fill the multiple geometric slots 12 within the rectangular slots 11 within a specified time. This can help train the difficulty and thus effectively achieve the training effect.

[0055] S3. When the second metal conveyor belt 10 is running, the hemispherical protrusion 20 also runs. The cooperation between the hemispherical protrusion 20, the push rod 21, and the tension spring 23 can drive the material holding plate 18 to rotate back and forth, which can move the geometric plate piled on the material holding plate 18 towards the first metal conveyor belt 4. In addition, when training, the user can place one hand on the rotating hemispherical protrusion 28 and place the fingers on the finger extension plate 26. When the material holding plate 18 rotates back and forth, the finger extension plate 26 can stretch the user's fingers, which can exercise the fingers of the elderly and increase the flexibility of the fingers.

[0056] S4. When the right end of the material holding plate 18 rotates upward, the material holding plate 18 can drive the one-way bearing 33 to rotate through the pull rope 34. The one-way bearing 33 and the round rod 31 are locked. The one-way bearing 33 drives the round rod 31 and the second bevel gear 32 to rotate. The second bevel gear 32 drives the rotating hemisphere 28 to rotate through the first bevel gear 30. The rotating hemisphere 28 drives the hemispherical protrusion on the outer wall to rotate, which can massage the user's palm and increase the user's comfort. When the material holding plate 18 rotates in the opposite direction, the second torsion spring 45 drives the one-way bearing 33 to rotate in the opposite direction. The one-way bearing 33 and the round rod 31 are in an active state. The one-way bearing 33 rewinds the pull rope 34 to facilitate the next rotation of the round rod 31.

[0057] S5. Pull the sliding plate 36 out of the outer casing 1. The display screen 35 can display photos of the user's relatives and friends. The bottom inner wall of the placement slot 37 is engraved with the words of parents, spouse, children, friends, brothers and colleagues. The user can put the geometric plate taken from the second metal conveyor belt 10 into the corresponding placement slot 37 according to the picture, further exercising the user's memory and logic ability.

[0058] S6. When the user is thirsty, the electromagnet 42 is activated through the control center 38. The electromagnet 42 and the magnetic disk 41 generate a magnetic attraction force, the drinking tube 40 moves up and pushes open the sealing cover 44, and the user can drink water through the drinking tube 40.

[0059] However, as is well known to those skilled in the art, the working principles and wiring methods of the control center 38, display screen 35, electric push rod 16 and electromagnet 42 are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
