Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to an ankle pump motion measuring device. Background Technology

[0002] In hospitals, patients with ankle injuries or those who are bedridden for extended periods need ankle pump exercises for rehabilitation or to reduce muscle atrophy and deep vein thrombosis caused by prolonged leg inactivity. Ankle pump exercises require not only dorsiflexion and plantarflexion movements, but also specific angles and repetitions. Additionally, foot rotations are necessary, with a required number of circles. During these exercises, patients cannot accurately determine whether they have achieved the correct range of motion or number of repetitions.

[0003] Therefore, there is a need to develop an ankle pump exercise measuring device that allows patients to easily understand whether the angle and number of their foot movements meet the standard. Utility Model Content

[0004] To address the aforementioned issues, the purpose of this invention is to provide an ankle pump motion measuring device that allows patients to easily understand whether the angle and number of their foot movements meet the standards.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An ankle pump motion measuring device mainly includes a base plate. Support plates are vertically mounted on both sides of the upper surface of the base plate. Each support plate has an arc-shaped sliding hole with the arc-shaped opening facing downwards. The two ends of the sliding hole are symmetrical about a vertical line. A rotating hole is provided on each support plate, located at the center of the arc of the sliding hole. A rotating plate is rotatably connected between two support plates. A rotating rod and a sliding rod are vertically mounted on each side of the rotating plate. The rotating rod is rotatably connected to the rotating hole, and the sliding rod is slidably connected to the sliding hole. A first nut is threaded onto both rotating rods, located on the outer side of the support plate (the side away from the base). A first counter and a second counter are detachably mounted on the outer side of one of the support plates, located at opposite ends of the sliding hole. Two first fixing straps for fixing the two insteps are installed on the front of the rotating plate. Long strip-shaped plate holes are provided on the surfaces of both support plates. The length direction of the hole is parallel to the vertical direction. A top plate is installed between the two support plates, and the top plate is located above the rotating plate. Connecting rods are installed at both ends of the length direction of the top plate. The connecting rods are slidably connected in the hole of the plate. A second nut is threaded onto the two connecting rods. The second nut abuts against the outer side of the support plate. The lower end face of the top plate is provided with two sliding areas. Each sliding area is located above a first fixing band. Each sliding area is composed of multiple concentric annular grooves. A sliding cylinder is slidably connected in each groove. The axis of the sliding cylinder is perpendicular to the bottom surface of the groove. The opening of the sliding cylinder faces downward. A vertical rod is detachably connected in the sliding cylinder. A connecting plate is installed at the lower end of the vertical rod. A second fixing band for fixing the instep is installed on the front of the connecting plate. A counter is provided at the bottom of the groove in each of the two sliding areas, namely a third counter and a fourth counter. The counting sensors of the third counter and the fourth counter are located in the groove. The display screens of the third counter and the fourth counter are located on the upper end face of the top plate.

[0007] Furthermore, the arc angle of the sliding hole is equal to 90 degrees.

[0008] Furthermore, the arc angle of the sliding hole is greater than 90 degrees. The limiting structure mainly includes a limiting screw and a limiting nut. The limiting screw is slidably connected to the sliding hole. The limiting screw is threadedly connected to the limiting screw. The head of the limiting screw abuts against the inner side of the support plate. The limiting nut abuts against the outer side of the support plate. The sliding rod is slidably connected between the two limiting structures. The counting sensors for the first counter and the second counter are respectively installed on the limiting nuts of the two limiting structures. The sensors are installed on the side between the two limiting nuts.

[0009] Furthermore, the outer side of the support plate is provided with an angle measuring ruler, the center of which coincides with the center of the rotating hole.

[0010] Furthermore, the upper surface of the base plate has two round-bottomed grooves, which are located below the two first fixing straps respectively.

[0011] Furthermore, an anti-wear pad is provided at the bottom of the groove.

[0012] Furthermore, an anti-slip pad is provided on the lower end surface of the base plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The rotating plate of this utility model rotates between two support plates. When the patient needs to perform dorsiflexion or plantarflexion, the patient's feet are fixed to the front of the rotating plate using the first fixing strap. The rotating plate rotates in the sliding hole through the sliding rod, so that the patient's feet can perform dorsiflexion or plantarflexion. The angle of dorsiflexion or plantarflexion is controlled by the arc angle of the sliding hole. When the sliding rod on the rotating plate slides to both ends in the sliding hole, it contacts the sensors of the first counter and the second counter respectively to count, so as to know whether the number of times the patient performs dorsiflexion or plantarflexion meets the standard.

[0015] 2. This utility model has a limiting structure in the sliding hole. When the patient's foot is in the early stage of recovery, the angle of dorsiflexion or plantarflexion of the foot is small. The limiting structure can limit the rotation angle of the rotating plate, thereby preventing excessive stretching of the foot and affecting the rehabilitation.

[0016] 3. This utility model has a top plate between two support plates. The top plate has two sliding areas with sliding cylinders slidably connected in the sliding grooves. When the patient needs to perform foot circling exercises, the patient's feet are fixed on the connecting plates connected to the sliding cylinders. When the patient's feet perform circling exercises, each connecting plate drives the sliding cylinder to slide in the sliding groove. The two sliding cylinders contact the sensors of the third and fourth counters in the sliding groove to count the number of circles, thereby knowing whether the number of circling exercises of the feet has reached the standard.

[0025] A specific embodiment, as shown in the figure, represents a preferred embodiment of this utility model. An ankle pump motion measuring device mainly includes a base plate 1. Support plates 3 are vertically mounted on the left and right sides of the upper surface of the base plate 1. Each support plate 3 has an arc-shaped sliding hole 4, with the arc-shaped opening of the sliding hole 4 facing downwards. The two ends of the sliding hole 4 are symmetrical about a vertical line. A rotating hole 22 is provided on the support plate 3, located at the center of the arc of the sliding hole 4. A rotating plate 14 is rotatably connected between two support plates 3. A rotating rod 19 and a sliding rod 6 are vertically mounted on each of the two sides of the rotating plate 14. The rotating rod 19 is rotatably connected within the rotating hole 22. The sliding rod 6 is slidably connected within the sliding hole 4. Two rotating rods 19 are threaded with first nuts 18, which are located on the outer side of the support plate 3. The outer side of the support plate 3 refers to the side away from the base. A first counter 15 and a second counter 16 are detachably mounted on the outer side of one of the support plates 3, located at opposite ends of the sliding hole 4. Two first fixing straps 13 are mounted on the front of the rotating plate 14 for securing the two insteps respectively. Long strips are formed on the surfaces of both support plates 3. Hole 7, the length direction of the plate hole 7 is parallel to the vertical direction, a top plate 9 is installed between the two support plates 3, the top plate 9 is located above the rotating plate 14, and connecting rods 8 are installed at both ends of the length direction of the top plate 9. The connecting rods 8 are slidably connected in the plate hole 7, and second nuts 12 are threaded onto the two connecting rods 8. The second nuts 12 abut against the outer side of the support plate 3. The lower end face of the top plate 9 is provided with two sliding areas, each of which is located above a first fixing band 13. Each sliding area is composed of multiple concentric annular grooves 20. Each sliding groove 20 is slidably connected to a sliding cylinder, the axis of which is perpendicular to the bottom surface of the sliding groove 20, and the opening of the sliding cylinder faces downward. A vertical rod 21 is detachably connected inside the sliding cylinder, and a connecting plate 11 is installed at the lower end of the vertical rod 21. A second fixing strap 10 for fixing the instep is installed on the front of the connecting plate 11. Each of the two sliding areas is provided with a counter at the bottom of the sliding groove 20, namely a third counter and a fourth counter. The counting sensors of the third counter and the fourth counter are located inside the sliding groove 20, and the display screens of the third counter and the fourth counter are located on the upper surface of the top plate 9.

[0026] In practical implementation, the base plate 1 is first placed at the foot of the bed. When the patient needs to perform dorsiflexion or plantarflexion exercises, the top plate 9 slides upward on the support plate 3, ensuring that the top plate 9 and the connecting plate 11 installed below it do not obstruct the rotation of the rotating plate 14. The patient lies on the bed with both feet placed on the base plate 1, and two first fixing straps 13 secure both feet to the front of the rotating plate 14. Then, the patient performs dorsiflexion or plantarflexion exercises, causing the feet to rotate the rotating plate 14 around the rotating rod 19. At this time, the sliding rod 6 on the rotating plate 14 slides back and forth within the sliding hole 4. Because the angles of dorsiflexion and plantarflexion generally need to reach 45 degrees to achieve the best training effect, the arc angle of the sliding hole 4 is further equal to 90 degrees. When the slide rod 6 slides to both ends of the slide hole 4, the two ends of the slide hole 4 act as limiters. Once the slide rod 6 reaches both ends of the slide hole 4, it indicates that the dorsiflexion and plantarflexion angles have reached 45 degrees. The patient can clearly know whether the dorsiflexion and plantarflexion angles have reached the optimal exercise requirements. Since dorsiflexion and plantarflexion movements require not only specific angles but also a certain number of repetitions, a first counter 15 and a second counter 16 are respectively installed at both ends of the slide hole 4. When the slide rod 6 slides to both ends of the slide hole 4, it contacts the counting sensors of the first counter 15 and the second counter 16 respectively. The first counter 15 and the second counter 16 count the dorsiflexion and plantarflexion movements, making it easy to check whether the patient's dorsiflexion and plantarflexion movement counts have met the target, thereby adjusting the training plan to achieve better training results.

[0027] However, for patients with ankle injuries, the angles of dorsiflexion and plantarflexion should not be too large when starting rehabilitation training to reduce strain on the wound. Therefore, furthermore, the arc angle of the sliding hole 4 is greater than 90 degrees, and both ends of the sliding hole 4 can be detachably installed with limiting structures. The limiting structures mainly include limiting screws 5 and limiting nuts 17. The limiting screws 5 are slidably connected to the sliding hole 4, and the limiting screws 5 are threadedly connected to the limiting screws 5. The head of the limiting screws 5 abuts against the inner side of the support plate 3, and the limiting nuts 17 abut against the outer side of the support plate 3. The sliding rod 6 is slidably connected between the two limiting structures. The counting sensors for the first counter 15 and the second counter 16 are respectively installed on the limiting nuts 17 of the two limiting structures, and the sensors are installed on the side between the two limiting nuts 17. Before performing dorsiflexion and plantarflexion exercises of the foot, firstly, slide the two limiting screws 5 into the sliding hole 4 to a suitable position so that the angle between the two limiting screws 5 is suitable for the patient's initial training. Then, fix the limiting screws 5 into the sliding hole 4 using the limiting nut 17. When the sliding rod 6 on the rotating plate 14 slides in the sliding hole 4 between the two limiting nuts 17, the sliding rod 6 contacts the sensors installed on the two limiting nuts 17 to count, thus facilitating the understanding of the patient's dorsiflexion and plantarflexion movements. This utility model adjusts the position of the limiting structure on the sliding hole 4 so that the angle between the two limiting nuts 17 is less than 90 degrees, that is, the angle of dorsiflexion and plantarflexion is less than 45 degrees. This angle is suitable for patients in the initial training and is not prone to injury. As the patient recovers, the angle between the two limiting nuts 17 can be gradually increased to 90 degrees so that the angle of dorsiflexion and plantarflexion is equal to 45 degrees, resulting in better therapeutic effects of dorsiflexion and plantarflexion exercises.

[0028] Furthermore, the outer side of the support plate 3 is provided with an angle measuring ruler, the center of which coincides with the center of the rotating hole 22. The angle between the two limiting structures can be adjusted by the angle measuring ruler, so as to select a suitable angle to assist movement according to the patient's rehabilitation and improve the treatment effect.

[0029] When the patient's foot needs to perform circular movements, because the angle of the sliding hole 4 is greater than 90 degrees, when the sliding rod 6 on the rotating plate 14 is slid to the rear end of the sliding hole 4, the position of the rotating plate 14 will not obstruct the movement of the connecting plate 11 around the sliding groove 20, allowing the patient's feet to be fixed on the connecting plate 11 and perform circular movements smoothly. Alternatively, when performing foot circular movements, the rotating plate 14 can be removed from between the two support plates 3 by unscrewing the first nut 18, so that the rotating plate 14 will not affect the foot circular movements. After the position of the rotating plate 14 is adjusted, the height of the top plate 9 is adjusted by sliding it downward on the plate hole 7 of the support plate 3 through the connecting rod 8, and then the position of the top plate 9 is fixed using the second nut 12, so that patients with different foot lengths can be fixed on the connecting plate 11. The patient's forefoot can be fixed to the connecting plate 11 through the second fixing strap 10. When the patient's foot is circular, due to physiological structure, the angle between the forefoot and the circular axis is basically the same. However, different foot lengths result in different diameters for the circular motion of the forefoot; patients with longer feet form a larger diameter for the circular motion than those with shorter feet. Therefore, multiple concentric grooves 20 are set in each sliding area. Patients with different foot lengths select grooves 20 with different diameters to fix the connecting plate 11, allowing them to complete the circular motion after their forefoot is fixed on the connecting plate 11. Simultaneously, different diameter grooves 20 can be selected based on the patient's foot recovery level. For initial circular motion training, a smaller diameter groove 20 can be used to assist training; as recovery progresses, a larger diameter groove 20 can be selected to improve training effectiveness. When the patient's feet are fixed on the connecting plate 11, their circular motion causes the connecting plate 11, which is fixed to the feet, to move the sliding cylinder within the groove 20. The sliding cylinders in the two sliding areas contact sensors in the third and fourth counters within the groove 20, respectively, to count the number of circular motions, allowing the patient to easily understand whether their circular motion has reached the target level.

[0030] Furthermore, the upper surface of the base plate 1 has two round-bottomed grooves 2, which are located below the two first fixing straps 13. The patient's heel is placed in the two grooves 2 to improve comfort.

[0031] Furthermore, the bottom of the groove 2 is provided with an anti-friction pad, which can reduce friction on the heel and improve comfort when the patient's foot moves.

[0032] Furthermore, the lower end surface of the base plate 1 is provided with an anti-slip pad, making it difficult for the base plate 1 to slide on the bed surface.

[0033] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
