Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a counting device for ankle pump movements. Background Technology

[0002] Ankle pump exercises are a type of rehabilitation exercise that involves actively and slowly dorsiflexing and pointing the toes (plantar flexion) to alternately contract and relax the calf muscles. During muscle contraction, the deep veins and lymphatic vessels are compressed, propelling blood and lymph back to the heart; during muscle relaxation, the venous valves prevent backflow and provide new blood flow for the next contraction. This repeated "muscle pump" effect accelerates blood circulation in the lower limbs, effectively preventing deep vein thrombosis.

[0003] The specific implementation method of ankle pump exercises is as follows: The patient lies flat on the bed with lower limbs extended and thighs relaxed. Slowly flex the toes, trying to point them towards oneself, and hold for 3-5 seconds at the maximum limit. Then slowly lower the toes, holding for 3-5 seconds at the maximum limit, and then relax. One flexion and one lowering constitutes one set. 20-30 sets should be performed each time, 5-8 times a day. In clinical practice, medical staff usually explain the steps and key points of the movements to the patient, and then family members assist or the patient records the exercise. However, this recording method is highly dependent on manual intervention. Family members or patients may sometimes forget or fail to record the exercise data accurately, and repeated inaccurate recordings may affect the patient's recovery. In addition, patients need to ensure that both flexion and extension of the foot reach the prescribed angle during exercise. Some patients proceed to the next step before reaching the prescribed angle, resulting in poor exercise effects and making it difficult to guarantee the expected recovery results.

[0004] Therefore, designing a counting device for ankle pump exercises that can accurately record the number of movements and effectively monitor whether the flexion and extension of the foot reach the specified angle is a technical problem that has not yet been solved in the existing technology. Summary of the Invention

[0016] The technical solution provided by this invention has the following advantages: This invention relates to a counting device for ankle pump exercises, comprising a U-shaped base, a first force-applying rod, a second force-applying rod, a reset elastic element, a first contact, a second contact, a control main board, a display screen, and a battery. The U-shaped base has symmetrically arranged first and second arc-shaped guide tracks on its left and right vertical plates, respectively. The first force-applying rod has two ends slidably mounted within the first arc-shaped guide tracks on both vertical plates. The second force-applying rod has two ends slidably mounted within the second arc-shaped guide tracks on both vertical plates. When both the first and second force-applying rods are in their initial positions, a space is formed between them. Two reset elastic elements are respectively installed between the ends of the first and second force-applying rods and are fixedly connected to them, for elastically resetting the first and second force-applying rods to their initial positions. Two first contacts are adjustablely mounted within the first arc-shaped guide tracks on both vertical plates. Two second contacts are adjustablely mounted within the second arc-shaped guide tracks on both vertical plates. Two control main boards are respectively fixedly mounted within the first arc-shaped guide tracks on both vertical plates. The system is fixedly installed inside the vertical plate. The control mainboard is equipped with a first trigger line, a second trigger line, and a reset button. The first trigger line of the left-side control mainboard is electrically connected to the left end of the first force-applying rod, and the second trigger line is electrically connected to the first contact point installed in the first arc-shaped guide slide of the left-side vertical plate. Each contact of the first and second trigger lines through the left end of the first force-applying rod and the first contact point increments the count by 1. The first trigger line of the right-side control mainboard is electrically connected to the right end of the second force-applying rod, and the second trigger line is electrically connected to the second contact point installed in the second arc-shaped guide slide of the right-side vertical plate. Each contact of the first and second trigger lines through the right end of the second force-applying rod and the second contact point increments the count by 1. The reset button is used to reset the count to zero. Two displays are fixedly installed on the vertical plate and electrically connected to the control mainboard, used to display the current count value in real time. Two batteries are fixedly installed inside the vertical plate and electrically connected to the control mainboard. Each battery has a power button, used to connect or disconnect the battery power supply to the control mainboard.

[0017] Before performing ankle pump exercises, place the U-shaped base stably on the bed, place your foot on the base, and insert your toes into the space between the first and second force-applying rods. Medical staff or family members should adjust the positions of the first and second contact points according to the patient's achievable or desired range of motion to set the target angles for pointing and flexing the foot. After adjustment, press the power button to connect the battery. During ankle pump exercises, the patient flexes their foot upwards, pushing the second force-applying rod along the second arc-shaped guide track. When the right end of the second force-applying rod touches the second contact point, the right control board sends a counting signal to the right display screen, which shows the number of times the foot is fully flexed. The patient then points their foot downwards, pushing the first force-applying rod along the first arc-shaped guide track. When the left end of the first force-applying rod touches the first contact point, the left control board sends a counting signal to the left display screen, which shows the number of times the foot is fully pointed. After the exercise, read the values ​​on both displays. Since a complete and effective ankle pump exercise must consist of one qualified flexion and one qualified extension, the smaller of the values ​​on the two screens represents the number of sets that the patient has truly completed with "quality and quantity."

[0018] This invention relates to a counting device for ankle pump exercises. It displays the number of times the foot is fully extended (flexed and pointed) on two separate screens, and the minimum value indicates the actual number of effective sets completed. Only when the foot actually moves the force bar to the contact point representing the target angle is the count recorded. This ensures that every recorded number represents a single, high-quality muscle pump contraction with the correct angle, providing reliable data for clinical rehabilitation outcomes.

Space 14; Two reset elastic elements 15 are respectively installed between the two ends of the first force-applying rod 2 and the second force-applying rod 3, and are respectively fixedly connected to the first force-applying rod 2 and the second force-applying rod 3, for elastically resetting the first force-applying rod 2 and the second force-applying rod 3 to their initial positions; Two first contacts 4 are adjustablely installed in the first arc-shaped guide slides 11 of the vertical plates 13 on both sides; Two second contacts 5 are adjustablely installed in the second arc-shaped guide slides 12 of the vertical plates 13 on both sides; Two control main boards 6 are respectively fixedly installed inside the vertical plates 13; The control main board 6 is provided with first contacts The control main board 6 on the left side has a first trigger line 61, a second trigger line 62, and a reset button 63.

Each contact between the first trigger line 61 and the second trigger line 62 through the left end of the first force-applying rod 2 and the first contact point 4 increments the count by 1. The control main board 6 on the right side has a first trigger line 61 electrically connected to the right end of the second force-applying rod 3, and the second trigger line 62 is electrically connected to the first contact point 4 installed in the first arc-shaped guide rail 11 on the right side of the vertical plate 13.

[0036] Before performing ankle pump exercises, place the U-shaped base 1 stably on the bed, place your foot on the base, and insert your toes into the placement space 14 between the first force-applying rod 2 and the second force-applying rod 3. Medical staff or family members should adjust the positions of the first contact point 4 and the second contact point 5 according to the range of motion the patient's ankle joint can achieve or needs to achieve, to set the target angles for pointing and flexing the foot. After adjustment, press the power button 71 to connect the battery 7 for power. During ankle pump exercises, the patient flexes their foot upwards, pushing the second force-applying rod 3 along the second arc-shaped guide slide 12.

[0040] In this embodiment, both the first contact 4 and the second contact 5 are provided in twos. One contact is responsible for contacting the force-applying rod to conduct electricity and generate a counting signal; the other contact is used for structural limiting, so that the force-applying rod is subjected to force at both ends when it is subjected to force, ensuring a smooth sliding process.

[0041] like Figure 5-6As shown, the first force-applying rod 2 includes a first main body rod 21 and a first conductive end 22 fixedly connected to both ends of the first main body rod 21; the first conductive end 22 at the left end is electrically connected to the first trigger line 61 of the control main board 6 on the left side, and can make conductive contact with the first contact point 4; the first main body rod 21 (the area in direct contact with the patient's foot) is made of insulating material, or wrapped with an insulating sheath such as rubber, silicone, or heat shrink tubing; the first conductive end 22 is made of conductive material. The second force-applying rod 3 includes a second main body rod 31 and a second conductive end 32 fixedly connected to both ends of the second main body rod 31; the second conductive end 32 at the right end is electrically connected to the first trigger line 61 of the control main board 6 on the right side, and can make conductive contact with the second contact point 5. The second main body rod 31 (the area in direct contact with the patient's instep) is made of insulating material, or wrapped with an insulating sheath such as rubber, silicone, or heat shrink tubing; the second conductive end 32 is made of conductive material.

[0044] The first main body rod 21 has a first limiting flange 25 at both ends; the first conductive end 22 has a second limiting flange 26; when the first guide end 22 is fixedly connected to the first main body rod 21, the first limiting flange 25 and the second limiting flange 26 slide in contact with the outer walls of both sides of the first arc-shaped guide slide 11; the second main body rod 31 has a third limiting flange 35 at both ends; the second conductive end 32 has a fourth limiting flange 36; when the second guide end 32 is fixedly connected to the second main body rod 31, the third limiting flange 35 and the fourth limiting flange 36 slide in contact with the outer walls of both sides of the second arc-shaped guide slide 12.

[0045] Arc-shaped auxiliary slides 16 are respectively provided on the inner sidewalls of the two vertical plates 13. The arc-shaped auxiliary slides 16 are opposite to the first arc-shaped guide slides 11 and the second arc-shaped guide slides 12 and have the same trajectory. An installation opening 17 is provided in the middle of the top wall of the arc-shaped auxiliary slide 16, and the installation opening 17 is connected to the arc-shaped auxiliary slide 16. When the force-applying rod is assembled onto the U-shaped base 1, the main rod is first installed into the arc-shaped auxiliary slide 16 through the installation opening 17, then the main rod is aligned with the arc-shaped guide slide, and then the conductive end is connected to the main rod from the outside, thereby assembling the force-applying rod onto the U-shaped base 1. The arc-shaped auxiliary slides 16 make the force-applying rod slide more smoothly and steadily during the sliding process.

The surface of the first movable seat 41 in contact with the first arc-shaped guide slide 11 is an arc-shaped surface with a matching curvature, so that the first movable seat 41 can slide smoothly along the first arc-shaped guide slide 11. When the position of the first contact 4 needs to be adjusted, first loosen the first adjusting nut 47 outward. At this time, the first movable seat 41 can drive the first contact 4 to slide smoothly in the first arc-shaped guide slide 11. After the first contact 4 is adjusted to the appropriate position, tighten the first adjusting nut 47 inward to limit and fix the first contact 4.The second contact 5 is installed in the second arc-shaped guide slide 12 in an adjustable position via a second adjustable mounting structure.

[0047] A soft pad 8 is fixedly installed on the top surface of the horizontal plate 18 of the U-shaped base 1. A groove 81 is formed in the middle of the top surface of the soft pad 8, and connecting grooves 82 are formed on the front and rear sides of the groove 81, respectively, communicating with the groove 81. The soft pad 8 improves the patient's comfort during ankle pump exercises. The patient places their foot in the groove 81 of the soft pad 8, which fits snugly against the heel, providing good support and cushioning. The connecting grooves 82 prevent the foot from slipping during exercise. If the patient's foot height is insufficient, the soft pad 8 can be removed, and a pad can be placed on the horizontal plate 18 below it to increase the overall height, and then the soft pad 8 can be put back in its original position.

[0048] like Figure 4 As shown, a first mounting position 19 and a second mounting position 20 are respectively provided on the vertical plates 13 on both sides; the control motherboard 6 and the display screen 64 are fixedly installed in the first mounting position 19; the battery 7 is fixedly installed in the second mounting position 20.

When it is necessary to repair the control main board 6, the maintenance cover 91 is first removed, and then the control main board 6 can be repaired through the maintenance opening 9.

[0050] The battery 7 is provided with a charging interface 72, which is adapted to be connected to an external power source to charge the battery 7.

[0051] The counting device used for ankle pump exercises in this embodiment is used as follows: Before performing ankle pump exercises, place the U-shaped base 1 stably on the bed, place the foot on the soft pad 8, place the heel in the groove 81, and extend the toes into the placement space 14 between the first force-applying rod 2 and the second force-applying rod 3. Medical staff or family members adjust the positions of the first contact point 4 and the second contact point 5 according to the range of motion of the patient's ankle joint (loosen the adjusting nut outward, at which point the movable seat can drive the contact point to slide smoothly in the arc-shaped guide slide; after adjusting to the appropriate position, tighten the adjusting nut inward to fix the contact point), so as to set the target angle for pointing and flexing the foot. After the adjustment is completed, press the power button 71 to connect the battery 7 for power supply. When performing ankle pump exercises, the patient flexes the foot upward, and the instep pushes the second force-applying rod 3 to move along the second arc-shaped guide slide 12; when the right end of the second force-applying rod 3 touches the second contact point 5, the right control main board 6 sends a counting signal to the right display screen 64, and the right display screen 64 displays the number of times the foot is flexed in real time. The patient points their toes downwards, pushing the first force-applying lever 2 along the first arc-shaped guide slide 11. When the left end of the first force-applying lever 2 touches the first contact point 4, the left control mainboard 6 sends a counting signal to the left display screen 64, which displays the number of times the toes are pointed in place in real time. After the exercise, the values ​​on both the left and right display screens 64 are read. Since a complete and effective ankle pump exercise must consist of one qualified toe flexion and one qualified toe point, the smaller of the values ​​on the two screens represents the number of sets the patient has truly completed with "quality and quantity."
