Description

Technical Field

[0001] The present invention relates to the field of ankle pump exercises, and specifically to an ankle pump exercise therapeutic apparatus. Background Art

[0002] Ankle pump exercise mobilizes the function of the calf muscle pump through the movement of the ankle joint. Through the contraction and relaxation of the muscles, it promotes blood circulation and lymphatic return in the lower extremities and prevents deep vein thrombosis in the lower extremities. It includes two movements: flexion and extension of the ankle joint and circumduction. With the ankle joint as the core, the soleus muscle and tibialis anterior muscle of the calf contract and relax regularly, jointly simulating the function of a pump, effectively reducing the formation of deep vein thrombosis.

[0003] Therefore, some patients need to perform ankle pump exercises frequently after surgery to maintain blood circulation and lymphatic return in the lower extremities. However, when patients actually exercise, due to incorrect movement postures, it is difficult to meet the standards of ankle pump exercises, resulting in the benefits of ankle pump exercises not being effectively realized. Therefore, patients often use therapeutic apparatuses to assist them in performing ankle pump exercises.

[0004] Existing ankle pump exercise therapeutic apparatuses drive the patient's foot to perform plantar flexion, dorsiflexion, and circumduction movements through methods such as motor drive, airbag inflation, or crank - connecting rod mechanisms, simulating normal ankle pump movements in the human body. However, different patients have different body shapes and different ankle positions. Since ankle pump exercise is a movement centered around the ankle joint, the ankle position is crucial. Generally, the positioning effect of therapeutic apparatuses on the ankle is poor and often cannot adapt to different patient body shapes. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an ankle pump exercise therapeutic apparatus to solve the technical problem of the poor positioning effect of general ankle pump exercise therapeutic apparatuses on the ankle.

[0006] To achieve the above - mentioned purpose, the present invention provides the following technical solution: An ankle pump exercise therapeutic apparatus includes a fixed seat. One end of the fixed seat is slidably provided with a movable plate. The top of the movable plate is fixedly provided with a mounting seat. One side of the mounting seat is movably provided with a positioning seat. On both sides of the top of the positioning seat, mounting frames are respectively installed. Inside the mounting frames, first motors are movably provided. The outer wall of the output end of the first motor is connected with a positioning column. The outer walls of the first motor and the positioning column are respectively rotatably connected with a plurality of telescopic cylinders. The fixed ends of the telescopic cylinders on the outer wall of the positioning column are rotatably connected with a positioning frame. One end of the positioning frame is connected with a top plate. One side of the top plate is fixedly provided with a fixed frame.

The outer wall of the rotating column is fixedly connected with the fixed frame. The outer wall of the rotating column is respectively provided with a first cylinder and a second cylinder. One end of the positioning seat is provided with a group of laser scanners.

[0007] The present invention is further configured such that one end of the top plate is connected with a touch plate, and a pressure sensor is installed between the top plate and the touch plate.

[0008] The present invention is further configured such that a third cylinder is installed inside the fixed seat, and the movable end of the third cylinder is connected with one end of the movable plate.

[0009] The present invention is further configured such that a fixed shell is fixedly arranged on the outer wall of the housing of the first motor, a plug post is fixedly arranged on the outer wall of the positioning post, the plug post and the fixed shell are mutually matched, a spring is arranged between the plug post and the inner bottom wall of the fixed shell, and an electric one-way valve is installed at one end of the fixed shell, and the air inlet end of the electric one-way valve is communicated with the inside of the fixed shell.

[0015] In summary, the present invention mainly has the following beneficial effects: The present invention drives the positioning seat to move towards the ankle position through the sliding movable plate. During the movement, the laser scanner scans the patient's ankle to confirm the position of the ankle and the position of the center line of the foot. The movement of the telescopic cylinder adjusts the positions of the first motor and the positioning post to align with the position of the ankle and confirm the position of the ankle flexion and extension movement. Then, the first cylinder and the second cylinder are started to control the position adjustment of the second motor and the rotating column to confirm the position of the center of the patient's sole. The positions of the patient's ankle and the center line of the foot are determined by the above structure. At this time, the movements during the ankle pump exercise are more standard and the treatment effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0027] An ankle pump exercise therapeutic apparatus, as Figures 1-9As shown in the figure, it includes a fixed seat 1. One end of the fixed seat 1 is slidably provided with a movable plate 2. A third cylinder 16 is installed inside the fixed seat 1. The movable end of the third cylinder 16 is connected to one end of the movable plate 2. A mounting seat 21 is fixedly provided on the top of the movable plate 2. One side of the mounting seat 21 is movably provided with a positioning seat 4. On both sides of the top of the positioning seat 4, mounting frames 5 are respectively installed. Inside the mounting frames 5, a first motor 6 is movably provided. The outer wall of the output end of the first motor 6 is connected with a positioning column 7. A plurality of telescopic cylinders 9 are respectively rotatably connected to the outer walls of the first motor 6 and the positioning column 7. The fixed end of the telescopic cylinder 9 on the outer wall of the positioning column 7 is rotatably connected to a positioning frame 8. One end of the positioning frame 8 is connected with a top plate 3. One end of the top plate 3 is connected with a touch plate 18. A pressure sensor is installed between the top plate 3 and the touch plate 18. One end of the positioning seat 4 is installed with a group of laser scanners 19.

[0028] When the patient places the leg on the fixed seat 1, start the third cylinder 16. The third cylinder 16 pulls the movable plate 2 to move towards the patient's foot position until the touch plate 18 touches the patient's sole. At this time, after the pressure sensor receives the signal, the third cylinder 16 is turned off. And during the movement, the laser scanner 19 is started. After being turned on, the laser scanner 19 will scan the patient's foot to record the shape of the foot, so as to confirm the position of the ankle and the center position of the foot.

[0029] Both the top of the fixed seat 1 and one end of the top plate 3 are provided with straps 17. After the position of the ankle is confirmed, use the straps 17 to fix the leg and the foot. Then the controller controls the movement of the telescopic cylinder 9 to adjust the positions of the first motor 6 and the positioning column 7, and align the positioning column 7 with the ankle position. After the ankle position is confirmed, the first motor 6 can be started. The first motor 6 drives the positioning column 7 to rotate reciprocally, and then drives the positioning frame 8 to rotate reciprocally synchronously. When the positioning frame 8 rotates, it will drive the top plate 3 to rotate reciprocally, realizing the flexion and extension movement of the patient's foot.

[0030] A fixed frame 12 is fixedly provided on one side of the top plate 3, and a second motor 13 is movably provided on one side of the mounting seat 21. The output end of the second motor 13 is connected to a rotating column 22. The outer wall of the rotating column 22 is fixedly connected to the fixed frame 12, and the outer wall of the rotating column 22 is respectively installed with a first cylinder 14 and a second cylinder 15. The movable end of the first cylinder 14 is connected to the rotating column 22 through a sleeve ring, and the sleeve ring is rotatably connected to the rotating column 22. The second cylinder 15 is fixedly installed inside the mounting seat 21, and the output end of the second cylinder 15 is fixedly connected to the rotating column 22. When the center position of the foot is confirmed, the first cylinder 14 and the second cylinder 15 are started to drive the second motor 13 and the rotating column 22 to move synchronously, and the rotating column 22 is aligned with the center position of the foot. After the position alignment is completed, the second motor 13 is started, and the second motor 13 drives the rotating column 22 to rotate. When the rotating column 22 rotates, the fixed frame 12 and the positioning seat 4 will rotate accordingly, so that the patient's foot moves left and right.

[0031] When the patient performs ankle pump exercise, due to certain differences between individuals, the ankle pump strength that each person can accept is also different. The outer wall of the shell of the first motor 6 is fixedly provided with a fixed shell 10, and the outer wall of the positioning column 7 is fixedly provided with a plug column 11, the plug column 11 and the fixed shell 10 match each other, and a spring is provided between the plug column 11 and the inner bottom wall of the fixed shell 10, and an electric one-way valve is installed at one end of the fixed shell 10, and the air inlet end of the electric one-way valve is connected with the interior of the fixed shell 10. After the patient's foot is fixed and the ankle position is confirmed, the electric one-way valve is opened, and the patient begins to try flexion and extension exercises, and the plug column 11 will be inserted into the fixed shell 10. At this time, the patient is found The two extreme flexion and extension points are acceptable to the patient. After finding the two extreme flexion and extension points, since the end of the plug post 11 located on the inner wall of the fixed shell 10 is provided with a conductive contact that is retractably connected by a spring and an arc strip, and the inner wall of the plug post 11 is provided with a graphite slide bar that cooperates with the conductive contact, when the plug post 11 slides, the position of the conductive contact and the graphite slide bar can be changed to control the rotation angle of the motor. The position of the conductive contact and the graphite slide bar can play a recording role. At this time, the first motor 6 can only rotate to the corresponding angle, which effectively prevents the patient from excessive flexion and extension and causing physical discomfort. The connection method between the above-mentioned conductive contact, the graphite slide bar and the first motor 6 is a prior art, so it is not described in detail.

[0032] When the patient no longer performs flexion and extension exercises, the electric one-way valve is closed at this time, and the electric one-way valve no longer performs one-way exhaust and is in a two-way ventilation state. The spring that was originally unable to reset due to the one-way exhaust of the electric one-way valve can be smoothly reset under the action of atmospheric pressure, thereby removing the restriction on the rotation angle of the first motor 6.

[0033] A groove is provided on the top of the fixing seat 1, and a sponge pad 20 is arranged inside the groove. The sponge pad 20 can effectively improve the comfort of the patient's legs and keep the patient's legs in the center position.

[0034] The first motor 6, the telescopic cylinder 9, the second motor 13, the first cylinder 14, the second cylinder 15 and the third cylinder 16 are all electrically connected to the controller. The specific connection method is not the main innovation point of this application, so no specific description is given to it. Those skilled in the art can choose appropriate connection methods and control methods for use.

[0035] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not make creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
