Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training instruments, and particularly relates to an ankle pump motion function assistor. Background Art

[0002] Ankle pump motion is a simple, easy-to-perform and effective lower limb function exercise method, which mainly promotes blood circulation and lymphatic return in the lower limbs through the movement of the ankle joint, and prevents the formation of lower limb venous thrombosis.

[0003] Ankle pump motion is divided into dorsiflexion motion, plantar flexion motion and ankle joint circumduction motion. The first two motion modes are relatively simple, so most patients often exercise through the first two motion modes. However, the latter exercise mode is difficult for patients after lower limb surgery. Often, after completing the dorsiflexion motion and plantar flexion motion, the ankle joint circumduction motion is considered.

[0004] For example, Chinese Patent No. CN220370164U discloses a countable ankle pump motion assistive training device, including a fixed ring and a fixed plate. One side of the bottom of the fixed ring is movably connected with a movable bolt, and the outside of the movable bolt is threadedly connected with a fixing cap. One side of the fixed ring is fixedly connected with a limiting plate, and a threaded rod is rotatably connected inside the limiting plate. One end of the threaded rod penetrates through the top of the limiting plate and is fixedly connected with a rocking wheel. Through the provided motor one, runner one and linkage plate one, the utility model can prompt the foot pedal to automatically drive the patient's foot to perform flexion and extension motions, thus avoiding the problem that the exercise effect is not obvious due to the inability to fully control the strength during traditional self-exercise. At the same time, through the provided motor two, runner two and linkage plate two, the exercise intensity of the patient's foot during flexion and extension motions can be adjusted, thus avoiding the problem of muscle damage caused by excessive motion amplitude.

[0005] The above-mentioned device drives the patient's ankle to move through motor one and linkage plate one, avoiding the situation that the patient's ankle is inconvenient to move in the early stage after surgery. The connection between linkage plate two and the foot pedal can improve the exercise intensity of the patient's foot during flexion, extension and plantar flexion motions. However, in order to better rehabilitate the ankle in the early stage after lower limb surgery, patients often need to perform periodic exercises on ankle pump motion. The existing ankle pump motion assistors mostly exercise and rehabilitate patients through the first two motion modes. Since dorsiflexion and plantar flexion motions are relatively simple for patients after surgery, patients rarely exercise the ankle joint circumduction motion. As a result, the patient's rehabilitation ability in this state is poor for exercising the entire set of ankle pump motion, lacking the effect of coordinated exercise among the three, thus prolonging the patient's rehabilitation course and further affecting the patient's postoperative state.

[0006] Therefore, this application provides an ankle pump motion function assistor to meet the needs. Content of the Utility Model

[0007] The technical problem to be solved by the present utility model is to provide an ankle pump motion function assistor to solve the problem that existing ankle pump motion assistors often use dorsiflexion and plantar flexion motions to rehabilitate postoperative patients, but there is less exercise for ankle circumduction motion, resulting in poor rehabilitation ability of patients in this state for exercising the entire set of ankle pump motions, lacking the effect of coordinated exercise among the three, thereby prolonging the rehabilitation course of patients and further affecting the postoperative state of patients.

[0008] To solve the above technical problems, the present utility model provides the following technical solutions:

[0009] An ankle pump motion function assistor, including an ankle pump motion assistor, a counting sensor is fixedly connected to the top of the ankle pump motion assistor, an arc-shaped support column is fixedly connected to the top of the ankle pump motion assistor, a horizontal support plate is installed at the top of the arc-shaped support column, and a trapezoidal connection plate is fixedly connected to the top of the ankle pump motion assistor; an adjustment component, the adjustment component is used to change the intensity of the ankle pump motion assistor during rotation, and the adjustment component is respectively connected to the ankle pump motion assistor and the horizontal support plate.

[0010] Optionally, the horizontal support plate includes a soft rubber pad fixedly connected to the top of the horizontal support plate, first weakening grooves are opened at both ends of the soft rubber pad, an everted curved panel is fixedly connected to the top of the soft rubber pad, adjustment grooves are fixedly connected to both ends of the top of the soft rubber pad, and a first inner cavity is opened in the middle of the soft rubber pad.

[0011] Optionally, an arc-shaped clamping plate is fixedly connected to the top of the horizontal support plate, a second inner cavity is opened in the middle of the arc-shaped clamping plate, second weakening grooves are opened on the inner wall of the arc-shaped clamping plate, a clamping end is opened on the inner wall of the arc-shaped clamping plate, and a movable ball is attached to the end of the arc-shaped clamping plate.

[0012] Optionally, the end of the adjustment groove is clamped in the inner cavity of the clamping end, and the inner wall of the everted curved panel is attached to the surface of the movable ball.

[0013] Optionally, a buffer pad is fixedly connected to the top of the trapezoidal connection plate, and the surface of the buffer pad is clamped at both ends of the horizontal support plate.

[0014] Optionally, the everted curved panel is made of plastic material and is symmetrically bent outward.

[0015] Optionally, the arc-shaped clamping plates are symmetrically distributed, and the arc surface of the arc-shaped clamping plate is adapted to the surface of the movable ball.

[0016] Optionally, a weakening point is opened at the connection between the top end of the soft rubber pad and the adjustment groove to facilitate the adjustment of the adjustment groove.

[0017] Optionally, the arc-shaped support column and the transverse support plate are connected by rolling balls, and the end of the transverse support plate is concave and adapted to the convex size of the buffer pad.

[0018] Optionally, the bottom end of the transverse support plate close to the trapezoidal connecting plate is inclined and adapted to the top inclination of the trapezoidal connecting plate, facilitating the sliding down of the transverse support plate.

[0019] Compared with the prior art, the utility model has at least the following beneficial effects:

[0020] In the above solution, by setting the adjusting component, when the patient makes ankle circumduction movements, the foot pedal in the ankle pump exercise assistor can be better fitted with the movable ball. This can not only prevent the patient from rotating randomly and generating uneven trajectories during ankle circumduction movements, but also select different intensities of circumduction movements according to the patient's actual control of the ankle, thereby improving the postoperative exercise of the lower limb postoperative patients by the ankle pump exercise and strengthening the rehabilitation effect of the ankle pump exercise on the lower limb postoperative patients.

[0021] By setting the second weakening groove, when the patient presses down the movable ball, the soft rubber pad will be pressed down synchronously. At this time, the adjusting groove will slide in the inner cavity of the clamping end, and the arc-shaped clamping plate will deform the second weakening groove under the pressing of the movable ball. Then, the arc-shaped clamping plate will gradually bend towards the middle position, so that the arc-shaped clamping plate wraps the surface of the movable ball, increasing the friction between the two. Further, the rotation effect of the movable ball will be weakened, improving the patient's control strength of ankle circumduction and increasing the intensity of the patient's exercise.

[0022] By setting the buffer pad, after the patient finishes the dorsiflexion movement and plantar flexion movement, it is necessary to press the transverse support plate obliquely downward to disengage it from the top of the trapezoidal connecting plate. At this time, the two ends of the transverse support plate will disengage along the buffer pad, and the inclined bottom of the transverse support plate will also slide out from the top of the trapezoidal connecting plate, enabling the movable ball to be quickly connected to the bottom of the foot pedal in the ankle pump exercise assistor, reflecting the flexibility of the device and improving the exercise effect.

[0036] As Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides an ankle pump motion function assistor, including an ankle pump motion assistor 1. A counting sensor 2 is fixedly connected to the top of the ankle pump motion assistor 1. An arc-shaped support column 3 is fixedly connected to the top of the ankle pump motion assistor 1. A transverse support plate 4 is installed at the top of the arc-shaped support column 3. A trapezoidal connection plate 5 is fixedly connected to the top of the ankle pump motion assistor 1; an adjustment component is used to change the intensity of the ankle pump motion assistor 1 during rotation. The adjustment component is respectively connected to the ankle pump motion assistor 1 and the transverse support plate 4. After the ankle pump motion assistor 1 completes dorsiflexion and plantar flexion movements, the foot pedal in the ankle pump motion assistor 1 is moved closer to the middle, away from the position in the middle of the ankle pump motion assistor 1. Then, the heel is pressed downward, so that the foot pedal is supported by the arc-shaped support column 3, and the transverse support plate 4 will also slide obliquely downward out of the trapezoidal connection plate 5 during the pressing process. Under the action of the adjustment component, the ankle joint circumduction movement is performed on the patient, and in combination with the use of the counting sensor 2, the cooperation between the arc-shaped support column 3, the transverse support plate 4 and the trapezoidal connection plate 5 enables the ankle joint circumduction movement to be connected more quickly after the dorsiflexion and plantar flexion movements are completed, facilitating counting and improving the subsequent rehabilitation ability of the patient.

[0037] As Figure 3 shown, the transverse support plate 4 includes a soft rubber pad 401 fixedly connected to the top of the transverse support plate 4. First weakening grooves 402 are opened at both ends of the soft rubber pad 401. An everted curved panel 403 is fixedly connected to the top of the soft rubber pad 401. Adjustment grooves 407 are fixedly connected to both ends of the top of the soft rubber pad 401. A first inner cavity is opened in the middle of the soft rubber pad 401. An arc-shaped clamping plate 404 is fixedly connected to the top of the transverse support plate 4. A second inner cavity is opened in the middle of the arc-shaped clamping plate 404. Second weakening grooves 405 are opened on the inner wall of the arc-shaped clamping plate 404. A clamping end 408 is opened on the inner wall of the arc-shaped clamping plate 404. A movable ball 406 is attached to the end of the arc-shaped clamping plate 404. The arc-shaped clamping plate 404 is made of plastic. When the movable ball 406 is pressed downward, the soft rubber pad 401 will be stressed and sink. At this time, the edge of the movable ball 406 will contact the second weakening groove 405. After the second weakening groove 405 is stressed, it will drive the arc-shaped clamping plate 404 to bend towards the position close to the movable ball 406. Since the arc shape of the arc-shaped clamping plate 404 is adapted to the shape of the movable ball 406, after the arc-shaped clamping plate 404 is bent, it will firmly clamp on the surface of the movable ball 406, and as the pressing force on the movable ball 406 increases, the inner wall of the arc-shaped clamping plate 404 and the movable ball 406 will fit more tightly, thereby increasing the friction between the two and further making it difficult for the movable ball 406 to rotate.

[0038] When the movable ball 406 is pressed downward, the top of the soft rubber pad 401 will sink under force. At this time, the adjustment groove 407 will descend along with it and come into contact with the clamping end 408. Since a weakening point is provided at the connection between the soft rubber pad 401 and the adjustment groove 407, the adjustment groove 407 will deflect during sliding, facilitating the adjustment groove 407 to be clamped in the inner cavity of the clamping end 408. After determining the position of the adjustment groove 407 in the clamping end 408, the weakening point will be clamped with the end of the clamping end 408. At this time, the adjustment groove 407 and the clamping end 408 are relatively fixed, and the adjustment groove 407 is not prone to deflection either. Thus, it is ensured that during the circumduction movement of the ankle joint, it will not easily fall off from the inside of the clamping end 408, improving the stability of the soft rubber pad 401.

[0039] As Figure 4 shown, a buffer pad 501 is fixedly connected to the top of the trapezoidal connecting plate 5. The surface of the buffer pad 501 is clamped at both ends of the horizontal support plate 4. When the ankle pump exercise assistor 1 presses downward, the bottom of the horizontal support plate 4 will be in close contact with the middle part of the trapezoidal connecting plate 5. The bottom end of the horizontal support plate 4 is set to be inclined, so that when it comes into contact with the trapezoidal connecting plate 5, it will continue to slide down along the inclined shape. Thus, the horizontal support plate 4 and the trapezoidal connecting plate 5 are separated from each other and the fixation is cancelled, enabling the circumduction movement of the ankle joint. When not in use, the concave shape at both ends of the horizontal support plate 4 is adapted to the convex shape of the buffer pad 501, and the ankle pump exercise assistor 1 is not pressed downward. Thus, the buffer pad 501 can support the horizontal support plate 4, preventing the movable ball 406 from directly contacting the foot pedal in the ankle pump exercise assistor 1.

[0040] The working principle of the technical solution provided by the present utility model is as follows: Before the patient performs ankle pump exercises, the ankle pump exercise assistor 1 is vertically placed and fixed at the end of the hospital bed near the feet. Then, the patient's toes are placed on the foot pedal and fixed. The driving motor will drive the patient's ankle to perform dorsiflexion and plantar flexion movements.

[0041] After the patient finishes the dorsiflexion and plantar flexion movements, the feet are brought together towards the middle. At this time, the foot pedal is separated from the middle support platform, and only the front end of the foot pedal is connected to the first linkage plate and the first motor. Then, the patient exerts force downward with the heel, causing the bottom of the foot pedal to come into contact with and be clamped to the movable ball 406. After complete clamping, the movable ball 406 will be inside the foot pedal and will not easily slide out.

[0042] Next, the patient presses with the heel, causing the force on the movable ball 406 to decrease, and driving the soft rubber pad 401 to be stressed downward. At this time, the adjustment groove 407 will slide on the surface of the clamping end 408 along the shape trajectory of the clamping end 408 driven by the soft rubber pad 401. The everted curved panel 403 can, on the one hand, prevent the displacement of the position of the movable ball 406, and on the other hand, when the movable ball 406 is pressed downward, it can generate a certain supporting force against the contact between the movable ball 406 and the inner wall of the everted curved panel 403, avoiding the movable ball 406 from being too loose when pressed downward and directly making the adjustment groove 407 in the lowermost clamping end 408. When entering the uppermost clamping end 408, the patient stops pressing and rotates the ankle to feel the intensity when the ankle rotates. And the foot pedal in the ankle pump exerciser 1 will contact the counting sensor 2 at the right-angled part of the end after one turn, completing one count. The patient can choose whether to adjust the position of the adjustment groove 407 in the clamping end 408 according to the contact point between the foot pedal and the counting sensor 2 or the difficulty when surrounding. The adjustment process is as above. After the movable ball 406 and the soft rubber pad 401 are lowered by pressing with the heel, the adjustment groove 407 will slide on the clamping ends 408 at different heights, so as to achieve the adjustment effect. When the adjustment groove 407 is lower, the extrusion effect of the second weakening groove 405 by the movable ball 406 is more obvious, so the deformation of the second weakening groove 405 is more obvious, making the arc-shaped clamping plate 404 bend more towards the middle. At this time, the inner wall of the arc-shaped clamping plate 404 will fit better with the surface of the movable ball 406, the clamping effect is better, the friction force is greater, and the intensity that the patient needs to rotate is higher.

[0043] When the heel presses downward, the horizontal support plate 4 will be driven to slide downward synchronously. Using the inclined bottom end of the horizontal support plate 4, it can directly slide down along the middle position of the trapezoidal connection plate 5 after being released from the clamping of the buffer pad 501. At this time, the horizontal support plate 4 is the sliding end descending and the rolling ball connection end rising, and the sliding has been completed before the adjustment groove 407 reaches the uppermost position of the clamping end 408. Then the above steps are carried out, and the patient rotates the ankle to feel whether the circumferential movement conforms to the current state of the patient himself.

[0044] After the ankle joint movement is over, first lift the heel and shake it slightly. At this time, the soft rubber pad 401 is no longer under downward pressure, so the first inner cavity will gradually rebound, and the slight shaking will accelerate the rebound speed, making the movable ball 406 loose and fall off. Then place the foot steadily, first close it towards the middle, and then place it on the support platform and relax. The foot pedal will bounce to both sides and fix the position. Then lift the horizontal support plate 4 with the hand and make the end of the horizontal support plate 4 clamped on the buffer pad 501, and then use the motor to do dorsiflexion and plantar flexion movements again, and then repeat the above process again.

[0045] The present utility model covers any alternatives, modifications, equivalent methods, and solutions made to the essence and scope of the present utility model. To enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, well-known methods, processes, procedures, components, and circuits are not described in detail to avoid unnecessary confusion to the essence of the present utility model.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
