Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a device for promoting ankle pump movement in the lower limbs. Background Technology
[0002] Ankle pump exercises refer to activities that accelerate blood circulation in the lower limbs through flexion and extension of the ankle joint. During ankle pump exercises, the relevant muscles of the thigh and calf will continuously contract and relax, which plays a very important role in the rehabilitation of patients who are bedridden for a long time or have lower limb fractures.
[0003] Currently, for patients who are bedridden for a long time or have lower limb fractures, ankle pump exercise devices are generally needed to assist them in performing ankle pump exercises. However, existing ankle pump exercise devices generally have a fixed initial angle when the foot is placed on the device, which cannot be adjusted according to the patient's physical condition and usage, and thus cannot meet the patient's needs. Therefore, in order to address the above problems, we have proposed an ankle pump exercise device. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a device for promoting lower limb ankle pump movement, which can be personalized according to the patient's physical condition and usage status to meet the patient's needs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lower limb ankle pump movement actuator, comprising a receiving seat, a locking assembly, and a driving assembly. A rotating rod is rotatably connected to the receiving seat, an adjusting seat is provided on the rotating rod, a rotating rod is rotatably connected to the adjusting seat, a rotating plate is provided on the rotating rod, and two support members for placing the foot are provided on the rotating plate. The locking assembly is provided on the receiving seat and is used to fix the rotation angle of the adjusting seat. The driving assembly is provided on the adjusting seat and is used to control the reciprocating rotation of the rotating rod, thereby enabling the support members to drive the flexion and extension movement of the ankle joint.
[0006] The beneficial effects of this utility model are as follows: by rotating the adjustment seat, the support member can be tilted at a certain angle to align with the patient, adapting to the patient's use, and the angle is fixed by the locking component. After the patient places both feet on the support member, the driving component drives the rotating rod two to rotate back and forth, thereby causing the support member to swing back and forth, realizing the flexion and extension movement of the ankle joint.
[0007] In order to fix the tilt angle of the adjustment seat;
[0008] As a further improvement to the above technical solution: the locking assembly includes multiple sockets and a plug rod adapted to the multiple sockets. The multiple sockets are all opened on the receiving seat, and the multiple sockets are equidistantly arranged along the central axis of the rotating rod. One end of the rotating rod extends to the outside of the receiving seat and is connected to a turntable. The plug rod is slidably connected to the turntable, and a spring is connected between the plug rod and the turntable.
[0009] The beneficial effects of this improvement are as follows: When appropriate adjustments are needed according to the patient's needs, pulling the insertion rod disengages it from the insertion hole, causing the spring to deform. This causes the rotating plate and support to rotate via the rotating adjustment seat. When the angle is suitable for the patient, the insertion rod is released, and under the elastic action of the spring, it is inserted into the corresponding insertion hole and fixed. At this point, the rotating rod is limited, and the tilt angle of the support changes, making it more convenient for the patient to use.
[0010] In order to drive the support and enable flexion and extension movements of the ankle joint;
[0011] As a further improvement to the above technical solution: the drive assembly includes a swinging component, a "Z"-shaped rod, and a motor mounted on the adjustment seat. The upper end of the swinging component is connected to the rotating rod. An elliptical groove is provided on the swinging component. One end of the "Z"-shaped rod is adapted to the elliptical groove and is movably connected inside the elliptical groove. The other end of the "Z"-shaped rod is connected to the motor.
[0012] The beneficial effects of this improvement are as follows: After the support is rotated to a certain angle and fixed, the motor is started. The motor drives the "Z"-shaped rod to rotate. One end of the "Z"-shaped rod moves in the elliptical groove, thereby causing the elliptical groove to swing left and right around the central axis of the fixed end of the "Z"-shaped rod. This causes the second rotating rod to rotate back and forth. The second rotating rod causes the rotating plate and the support to swing back and forth, thereby causing the ankle joint to perform flexion and extension ankle pump movements.
[0013] To provide support and stability for the feet;
[0014] As a further improvement to the above technical solution: the support includes a foot plate and a heel portion connected to one end of the foot plate, and both the foot plate and the heel portion are provided with fixing straps for fixing the foot.
[0015] The beneficial effects of this improvement are as follows: When using the product, place your foot on the footboard, then place your heel against the instep, and then fix the strap to the instep to secure the foot, thus making it easier for the support to move the foot during the reciprocating swing.
[0016] To facilitate inserting the plug into the socket;
[0017] As a further improvement to the above technical solution: one end of the insertion rod is provided with a pointed head.
[0018] The beneficial effects of this improvement are: the pointed tip reduces the contact area of the insert rod when it is inserted into the socket under the elastic action of the spring, making it easier to insert and facilitating user operation.
[0019] To increase the stability of this device;
[0020] As a further improvement to the above technical solution: the bottom of the receiving seat is provided with an anti-slip pad.
[0021] The beneficial effects of this improvement are: the support base can be used in a wider range of places, and the anti-slip pad can increase the friction with the placement surface, preventing the device from shifting during use and increasing the stability of the device.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0030] like Figure 1-6As shown, a lower limb ankle pump exercise device includes a support base 1, a rotating rod 2 rotatably connected to the support base 1, an adjusting seat 3 on the rotating rod 2, a rotating rod 4 rotatably connected to the adjusting seat 3, and a rotating plate 5 on the rotating rod 4. The rotating plate 5 has two support members for placing the foot. During use, the angle of the support members can be adjusted according to the patient's posture. For example, when the patient is seated, the support members are parallel to the support base 1; when the patient is in a semi-recumbent position, the support members need to be tilted towards the patient and form a certain angle with the support base 1. It also includes a locking component and a driving component. The locking component is located on the receiving seat 1 and is used to fix the rotation angle of the adjusting seat 3. The driving component is located on the adjusting seat 3 and is used to control the reciprocating rotation of the rotating rod 4 to realize the support member driving the ankle joint to flex and extend. When in use, the adjusting seat 3 is rotated, and the adjusting seat 3 drives the rotating rod 2 to rotate, so that the tilt angle of the support member is suitable for the patient to use. Then it is fixed by the locking component. After the fixing is completed, the driving component controls the rotating rod 4 to reciprocate, and causes the rotating plate 5 and the support member to reciprocate, thereby driving the two feet on the support member to perform flexion and extension reciprocating movements.
[0031] Furthermore, the locking assembly includes multiple insertion holes 701 and insertion rods 702 adapted to the multiple insertion holes 701. The multiple insertion holes 701 are all opened on the receiving seat 1, and the multiple insertion holes 701 are equidistantly arranged along the central axis of the rotating rod 2. One end of the rotating rod 2 extends to the outside of the receiving seat 1 and is connected to a turntable 9. The insertion rod 702 is slidably connected to the turntable 9. A spring 10 is connected between the insertion rod 702 and the turntable 9. In use, by pulling the insertion rod 702, it slides on the turntable 9. The insertion rod 702 causes the spring 10 to deform and disengage from the insertion hole 701. Then, after rotating the adjusting seat 3 by a certain angle, the insertion rod 702 is released. Under the elastic action of the spring 10, the insertion rod 702 is inserted into the insertion hole 701 for fixation. At this time, the adjusting seat 3 is fixed in a suitable position for patient use.
[0032] Furthermore, the drive assembly includes a swing element 801, a "Z"-shaped rod 802, and a motor 803 mounted on the adjustment seat 3. The upper end of the swing element 801 is connected to the rotating rod 4. An elliptical groove 11 is formed on the swing element 801. One end of the "Z"-shaped rod 802 is adapted to and movably connected inside the elliptical groove 11, and the other end of the "Z"-shaped rod 802 is connected to the motor 803. The motor 803 can be a reduction motor 803, which drives the rotating rod 4 to move slowly. After the adjusting seat 3 drives the support to rotate to a certain angle and fix it, the motor 803 is started. The motor 803 drives the "Z"-shaped rod 802 to rotate. One end of the "Z"-shaped rod 802 moves in the elliptical groove 11 and moves along the elliptical groove 11, thereby causing the elliptical groove 11 to swing left and right about the central axis of the fixed end of the "Z"-shaped rod 802, thereby causing the rotating rod 4 to rotate back and forth. The rotating rod 4 drives the rotating plate 5 and the support to swing back and forth, while the foot on the support flexes and extends forward and backward, causing the ankle joint to perform ankle pump movement.
[0033] Furthermore, the support includes a foot plate 601 and a heel portion 602 connected to one end of the foot plate 601. Both the foot plate 601 and the heel portion 602 are provided with fixing straps 12 for fixing the foot. The height of the heel portion 602 should not exceed the ankle joint to avoid wear and tear on the heel during ankle flexion and extension movements. In use, the foot is placed on the foot plate 601, and then the heel is pressed against the heel portion 602. The fixing straps 12 are then fixed to the instep. The fixing straps 12 can be fixed with Velcro or two corresponding fixing straps 12 can be tied together to fix the foot, thereby fixing the foot and facilitating the movement of the foot during the reciprocating swing of the support.
[0034] Furthermore, one end of the insertion rod 702 is provided with a pointed head 13. When the insertion rod 702 is inserted into the insertion hole 701 under the elastic action of the spring 10, the pointed head 13 reduces the contact area of the insertion rod 702, making it easier to insert into the insertion hole 701 and facilitating user operation.
[0035] Furthermore, the bottom of the receiving seat 1 is provided with an anti-slip pad 14, which can be made of materials such as rubber or silicone. The receiving seat 1 is used in a wide range of applications, and the anti-slip pad 14 increases the friction with the placement surface, preventing the device from shifting during use and increasing its stability.
[0036] The working principle and usage process of this utility model are as follows: When using this device, first move it to a suitable position, and then adjust it according to the patient's needs. By pulling the insertion rod 702 out of the insertion hole 701, the spring 10 deforms. Then, rotate the adjusting seat 3, which drives the rotating rod 2, the rotating plate 5, and the support to rotate. When the tilt angle of the support is suitable for the patient's use, release the insertion rod 702. The tip 13 of the insertion rod 702 is inserted into the corresponding insertion hole 701 under the elastic action of the spring 10, fixing the rotating rod 2, thereby fixing the adjusting seat 3 to a suitable angle. Then, place the patient's feet... On the footplate 601, the heel is pressed against the heel part 602 and fixed by the fixing strap 12. Then, the motor 803 is started, and the motor 803 drives the "Z"-shaped rod 802 to rotate. The movable end of the "Z"-shaped rod 802 moves in the elliptical groove 11, causing the swinging part 801 to swing around the central axis of the fixed end of the "Z"-shaped rod 802, thereby driving the rotating rod 4 to rotate back and forth. Then, the rotating plate 5 and the support part swing back and forth, thereby causing the foot to drive the ankle joint to flex and extend. During the use of this utility model, it can be personalized according to the patient's physical condition and usage state to meet the patient's usage needs and make it more convenient.
