Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ankle pump exercise device. Background Technology

[0002] Ankle pump exercises promote blood circulation and lymphatic drainage in the lower limbs by moving the ankle joint like a pump. The exercise method is simple, easy to perform, and effective, which is beneficial for the rehabilitation of patients after lower limb surgery or injury. It can also promote blood circulation, prevent venous thrombosis, and reduce swelling. Therefore, patients are often encouraged to do more ankle pump exercises during rehabilitation. When patients' lower limbs are relatively weak, hospitals often use ankle pump exercise devices to assist them in performing ankle pump exercises.

[0003] Existing ankle pump exercise devices can usually only assist patients in performing forward and backward extension movements, but cannot assist them in performing circumferential movements. The limited range of movement modes affects the effectiveness of patients' rehabilitation exercises. Utility Model Content

[0004] The purpose of this invention is to provide an ankle pump exercise device that increases exercise modes and improves the rehabilitation effect of patients.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ankle pump exercise device, comprising a housing, wherein a notch is provided through the upper end face of the housing, a mounting frame is rotatably connected inside the notch, a telescopic rod is rotatably connected inside the mounting frame, a foot pedal located above the housing is fixedly connected to the upper end face of the telescopic rod, and a universal joint located inside the housing is rotatably connected to the lower end of the telescopic rod through a hinge.

[0006] The lower inner end of the outer casing is slidably connected to two mounting blocks distributed on the left and right. A first lead screw is rotatably connected between the two mounting blocks. A moving block is threadedly connected to the outer wall of the first lead screw. The upper end face of the moving block is rotatably connected to a universal joint through a hinge.

[0007] The lower interior of the outer casing is fixedly connected to two front-to-back fixed blocks, and a second lead screw is rotatably connected between the two fixed blocks and threadedly connected to the mounting block located on the left side.

[0008] In order to support the patient's lower leg, as a preferred embodiment of the ankle pump exercise device of this utility model, a mounting plate is fixedly connected to the lower right side wall of the outer shell, a vertical rod is fixedly connected to the upper end of the mounting plate, and the other end of the vertical rod is rotatably connected to a leg support plate through a hinge seat, and the vertical rod and the hinge seat are tightly connected.

[0009] In order to drive the first lead screw to rotate, as a preferred embodiment of the ankle pump exercise device of this utility model, a first motor is installed inside the right mounting block, and the output end of the first motor is fixedly connected to the first lead screw.

[0010] In order to drive the second lead screw to rotate, as a preferred embodiment of the ankle pump exercise device of this utility model, a second motor is installed inside the rear fixed block, and the output end of the second motor is fixedly connected to the second lead screw.

[0011] In order to limit and fix the patient's feet and lower legs, as a preferred embodiment of the ankle pump exercise device of this utility model, two front-to-back straps are fixedly connected to the right side wall of the foot pedal and the upper end face of the leg support plate, and the two straps are fixed together by Velcro.

[0012] In order to enable the two mounting blocks to move smoothly, as a preferred embodiment of the ankle pump exercise device of this utility model, the two mounting blocks are slidably connected to the lower end of the inner shell through a sliding groove and a slider.

[0013] To increase patient comfort in the lower leg, the leg support plate of this invention is preferably configured as an arc-shaped structure in an ankle pump exercise device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The first motor drives the first lead screw to rotate clockwise, which in turn drives the moving block to move to the left. The moving block, in conjunction with the universal joint, drives the telescopic rod to rotate within the mounting frame, causing the foot pedal to move to the right. Simultaneously, the second motor drives the second lead screw to rotate clockwise, which in turn drives the mounting block located on the left side to move forward. The mounting block located on the left side, in conjunction with the first lead screw, drives the moving block to move forward, making the moving block's trajectory an arc. The moving block, in conjunction with the universal joint, telescopic rod, and mounting frame, drives the foot pedal to move backward, making the foot pedal's trajectory opposite to that of the moving block.

[0016] When the moving block moves to the middle of the first lead screw, the second lead screw rotates counterclockwise, causing the mounting block on the left to move backward. This causes the moving block to move backward, which in turn causes the foot pedal to move forward until the moving block reaches the leftmost end of the first lead screw, making the foot pedal's movement path a semicircle. Then, the first lead screw rotates counterclockwise, causing the moving block to move to the right, which in turn causes the foot pedal to move to the left. When the moving block moves back to the middle of the first lead screw, the second lead screw rotates clockwise, causing the mounting block on the left to move forward. This causes the moving block to move forward, which in turn causes the foot pedal to move backward until the moving block reaches the rightmost end of the first lead screw, making the foot pedal's movement path a circle. This process assists the patient in performing circular movements of the foot.

[0017] When stretching exercises are needed for the patient's feet, simply rotate the first lead screw. The first lead screw drives the moving block to move back and forth, which in turn causes the foot pedal to swing back and forth, thereby stretching the patient's feet. Attached Figure Description

[0023] Please see Figures 1 to 3 An ankle pump exercise device includes a housing 1, with a notch 2 extending through the upper end face of the housing 1. A mounting frame 3 is rotatably connected inside the notch 2, and a telescopic rod 4 is rotatably connected inside the mounting frame 3. A foot pedal 5 located above the housing 1 is fixedly connected to the upper end face of the telescopic rod 4, and a universal joint 6 located inside the housing 1 is rotatably connected to the lower end of the telescopic rod 4 through a hinge.

[0024] The lower inner end of the outer casing 1 is slidably connected to two left and right distributed mounting blocks 7. A first lead screw 8 is rotatably connected between the two mounting blocks 7. A movable block 9 is threadedly connected to the outer wall of the first lead screw 8. The upper end face of the movable block 9 is rotatably connected to the universal joint 6 through a hinge seat.

[0025] The lower interior of the outer casing 1 is fixedly connected to two front-to-back fixed blocks 11, and a second lead screw 12 is rotatably connected between the two fixed blocks 11 and threadedly connected to the mounting block 7 located on the left side.

[0026] In this embodiment: When in use, the patient places their feet on the foot pedal 5, then places their lower legs on the leg support plate 15, and fixes the patient's feet and lower legs with the straps 10;

[0027] Then, the first lead screw 8 rotates clockwise, causing the moving block 9 to move to the left. The moving block 9, in conjunction with the universal joint 6, causes the telescopic rod 4 to rotate within the mounting frame 3, causing the foot pedal 5 to move to the right. At the same time, the second lead screw 12 rotates clockwise, causing the mounting block 7 located on the left to move forward. The mounting block 7 located on the left, in conjunction with the first lead screw 8, causes the moving block 9 to move forward, making the movement trajectory of the moving block 9 an arc. The moving block 9, in conjunction with the universal joint 6, the telescopic rod 4, and the mounting frame 3, causes the foot pedal 5 to move backward, making the movement trajectory of the foot pedal 5 opposite to that of the moving block 9.

[0028] When the moving block 9 moves to the middle of the first lead screw 8, the second lead screw 12 rotates counterclockwise. The second lead screw 12 drives the mounting block 7 on the left to move backward, causing the moving block 9 to move backward, which in turn causes the foot pedal 5 to move forward until the moving block 9 moves to the leftmost end of the first lead screw 8, making the movement trajectory of the foot pedal 5 form a semicircle. Then the first lead screw 8 rotates counterclockwise, causing the moving block 9 to move to the right, making the foot pedal 5 move to the left. When the moving block 9 moves to the middle of the first lead screw 8 again, the second lead screw 12 rotates clockwise, causing the mounting block 7 on the left to move forward, causing the moving block 9 to move forward, which in turn causes the foot pedal 5 to move backward, until the moving block 9 moves to the rightmost end of the first lead screw 8, making the movement trajectory of the foot pedal 5 form a circle, thus assisting the patient's foot in making circular movements.

[0029] When it is necessary to perform stretching exercises on the patient's feet, simply rotate the first lead screw 8. The first lead screw 8 drives the moving block 9 to move back and forth, thereby causing the foot pedal 5 to swing back and forth, thus performing stretching exercises on the patient's feet.

[0030] As a technical optimization of this utility model, a mounting plate 13 is fixedly connected to the lower right side wall of the outer shell 1, and a vertical rod 14 is fixedly connected to the upper end of the mounting plate 13. The other end of the vertical rod 14 is rotatably connected to a leg support plate 15 through a hinge seat, and the vertical rod 14 is tightly connected to the hinge seat.

[0031] In this embodiment, the leg support plate 15 can support the patient's lower leg. Since the vertical rod 14 is tightly connected to the hinge seat, the leg support plate 15 can be suspended at any position.

[0032] As a technical optimization of this utility model, a first motor 16 is installed inside the mounting block 7 on the right side, and the output end of the first motor 16 is fixedly connected to the first lead screw 8.

[0033] In this embodiment: the first motor 16 is started, and the first motor 16 drives the first lead screw 8 to rotate.

[0034] As a technical optimization of this utility model, a second motor 17 is installed inside the rear fixing block 11, and the output end of the second motor 17 is fixedly connected to the second lead screw 12.

[0035] In this embodiment: the second motor 17 is started, and the second motor 17 drives the second lead screw 12 to rotate.

[0036] As a technical optimization of this utility model, two front-to-back straps 10 are fixedly connected to the right side wall of the foot pedal 5 and the upper end face of the leg support plate 15, and the two straps 10 are fixed together by Velcro.

[0037] In this embodiment, the strap 10 can limit and fix the patient's feet and lower legs.

[0038] As a technical optimization of this utility model, the two mounting blocks 7 are slidably connected to the lower end of the inner shell 1 through a sliding groove and a slider.

[0039] In this embodiment, the slide and slider enable the two mounting blocks 7 to move smoothly.

[0040] As a technical optimization of this utility model, the leg support plate 15 is configured as an arc-shaped structure.

[0041] In this embodiment, the leg support plate 15 is set with an arc-shaped structure, which allows the leg support plate 15 to fit the patient's lower leg and increase the patient's lower leg comfort.

[0042] Working principle: When in use, the patient places their feet on the foot pedal 5, then places their lower legs on the leg support plate 15, and fixes the patient's feet and lower legs with the straps 10;

[0043] Then, the first motor 16 is started, which drives the first lead screw 8 to rotate clockwise. The first lead screw 8 drives the moving block 9 to move to the left. The moving block 9, in conjunction with the universal joint 6, drives the telescopic rod 4 to rotate within the mounting frame 3, causing the foot pedal 5 to move to the right. At the same time, the second motor 17 is started, which drives the second lead screw 12 to rotate clockwise. The second lead screw 12 drives the mounting block 7 located on the left to move forward.

The moving block 9, in conjunction with the universal joint 6, the telescopic rod 4, and the mounting frame 3, drives the foot pedal 5 to move backward, so that the moving trajectory of the foot pedal 5 is opposite to the moving trajectory of the moving block 9.

[0044] When the moving block 9 moves to the middle of the first lead screw 8, the second lead screw 12 rotates counterclockwise. The second lead screw 12 drives the mounting block 7 on the left to move backward, causing the moving block 9 to move backward, which in turn causes the foot pedal 5 to move forward until the moving block 9 moves to the leftmost end of the first lead screw 8, making the movement trajectory of the foot pedal 5 form a semicircle. Then the first lead screw 8 rotates counterclockwise, causing the moving block 9 to move to the right, making the foot pedal 5 move to the left. When the moving block 9 moves to the middle of the first lead screw 8 again, the second lead screw 12 rotates clockwise, causing the mounting block 7 on the left to move forward, causing the moving block 9 to move forward, which in turn causes the foot pedal 5 to move backward, until the moving block 9 moves to the rightmost end of the first lead screw 8, making the movement trajectory of the foot pedal 5 form a circle, thus assisting the patient's foot in making circular movements.

[0045] When it is necessary to perform stretching exercises on the patient's feet, simply rotate the first lead screw 8. The first lead screw 8 drives the moving block 9 to move back and forth, thereby causing the foot pedal 5 to swing back and forth, thus performing stretching exercises on the patient's feet.
