Description

Technical Field

[0001] This utility model belongs to the technical field of human ankle training and ankle exercise rehabilitation technology, specifically relating to an infrared ankle pump motion counter. Background Technology

[0002] For patients who are bedridden for extended periods and lack walking exercise, their lower limb muscles are prone to atrophy and deep vein thrombosis. Therefore, these patients usually need to get out of bed and move around as soon as possible to reduce the stimulation of blood circulation caused by muscle atrophy in the lower limbs. Some patients already experience mobility difficulties due to underlying medical conditions such as fractures or lower limb muscle atrophy.

[0003] To assist patients in lower limb training, such as Figure 1 and Figure 2 As shown, some hospitals have already put into use the "Lower Limb Ankle Pump Functional Training Device," which is specifically designed to address the difficulty of bedridden patients performing lower limb functional exercises well or inadequately. It mainly consists of a fixed frame 01, an eccentric wheel 02, and a traction pedal 03. The eccentric wheel 02 is rotatably mounted on the fixed frame 01. The traction pedal 03 has a linkage structure, with one part hinged to the eccentric wheel 02 and the other part connected to the fixed frame 01. During use, the patient places their foot on the pedal of the traction pedal 03. The motor activates the eccentric wheel 02, causing the traction pedal 03 to rotate back and forth, thus simulating dorsiflexion and plantarflexion movements of the foot, thereby assisting in lower limb training.

[0004] However, with the increase in patients using it, some feedback has frequently arisen: Because the rotation angle of the traction pedal 03 is relatively fixed, and patients' feet vary in size and ligaments differ from person to person, those with poor muscle and ligament function are not suitable for large-amplitude movements. Excessive intensity can even lead to foot injury. Therefore, from an auxiliary rehabilitation perspective, allowing patients to spontaneously perform dorsiflexion and plantarflexion movements, and ensuring that each movement meets the specified standard, can achieve better rehabilitation results after long-term training. Currently, there is no rehabilitation device available for patients to perform dorsiflexion and plantarflexion movements and for checking the accuracy of these movements. Therefore, there is room for improvement. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an infrared ankle pump motion counter that allows patients to perform dorsiflexion and plantarflexion movements and can check whether the movements are in place, which helps to improve safety and enhance the effect of assisted exercise.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An infrared ankle pump exercise counter includes two supports and a flexible component disposed between the two supports, forming a training area for the foot to be placed between the two supports. Each support is provided with an upper slide rail, a lower slide rail, and a counting circuit. The upper and lower slide rails are arranged vertically. A dorsiflexion infrared sensor is slidably disposed on the upper slide rail, and a plantarflexion infrared sensor is slidably disposed on the lower slide rail. The sensing ends of both the dorsiflexion and plantarflexion infrared sensors face the training area. Both the dorsiflexion and plantarflexion infrared sensors are electrically connected to the counting circuit. When both the dorsiflexion and plantarflexion infrared sensors detect the foot within one exercise cycle, the counting circuit completes one count.

[0008] Furthermore, the structures of the dorsal infrared sensor and the plantar flexion infrared sensor are identical. The dorsal infrared sensor includes a sliding rod, a sliding member, and an infrared sensor. One end of the sliding rod is slidably engaged with the upper slide rail. The sliding rod is perpendicular to the horizontal plane. The sliding member is slidably connected to the sliding rod. The sliding member slides along the length direction of the sliding rod. The infrared sensor is mounted on the sliding member.

[0009] Furthermore, the sliding component includes a connecting block and a bolt, as well as connecting pieces disposed on opposite sides of the connecting block. The two connecting pieces are bent and surround the sliding rod, with their ends overlapping. Each end of the two connecting pieces has a screw hole, and the screw holes of the two connecting pieces are opposite to each other. The bolt is threadedly connected to the two screw holes, and the end of the bolt abuts against the sliding rod to restrict the sliding of the sliding component.

[0010] Furthermore, the bracket includes a base, a support rod, and a support platform. The bottom end of the support rod is disposed on the base, the support platform is disposed on the top end of the support rod, and the dorsal extension infrared sensor and the plantar flexion infrared sensor are respectively disposed on the upper and lower sides of the support platform.

[0011] Furthermore, an upper frame is provided on the top surface of the support platform, forming a space between the upper frame and the support platform for the movement of the dorsal infrared sensor. An upper slide rail is provided on the top surface of the support platform, and a first slide groove is provided on the upper frame corresponding to the upper slide rail, the first slide groove for the sliding rod end to slide in contact with the slide rail. A lower frame is provided on the bottom surface of the support platform, forming a space between the lower frame and the support platform for the movement of the plantar flexion infrared sensor. A lower slide rail is provided on the bottom surface of the support platform, and a second slide groove is provided on the lower frame corresponding to the lower slide rail, the second slide groove for the sliding rod end to slide in contact with the slide rail.

[0012] Furthermore, a metal block is provided at the end of the sliding rod away from the upper or lower slide rail. The metal block abuts against the top surface of the upper frame or the bottom surface of the lower frame. A plurality of magnetic blocks are provided on the top surface of the upper frame and the bottom surface of the lower frame. The plurality of magnetic blocks on the upper frame are located on the side close to the first slide groove and are evenly distributed along the extension direction of the first slide groove, covering the movement range of the metal block when it moves. The plurality of magnetic blocks on the lower frame are located on the side close to the second slide groove and are evenly distributed along the extension direction of the second slide groove, covering the movement range of the metal block when it moves.

[0013] Furthermore, measuring rulers are provided on the top surface of the upper span and the bottom surface of the lower span.

[0014] Furthermore, the flexible component is made of elastic rope or spring.

[0015] Furthermore, a connecting pad is provided between the two brackets.

[0016] This utility model has the following beneficial effects:

[0017] This invention incorporates a flexible component between two supports, allowing patients to perform voluntary dorsiflexion and plantarflexion movements. Adjustable infrared sensors for dorsiflexion and plantarflexion are mounted on the supports to detect the accuracy of these movements, verifying their proper execution. When the movements meet the required standards, a counting circuit is triggered to complete one exercise cycle, facilitating self-checking by the patient. Compared to existing technologies that use electric mechanical assistance, where the mechanical motion is relatively fixed, this infrared ankle pump motion counter relies primarily on the patient's voluntary participation, thus improving safety and the effectiveness of the assisted exercise.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.

[0026] This invention addresses the shortcomings of existing automatic lower limb ankle pump exercise devices, which rely on fixed, electrically powered mechanical movements that may not be suitable for everyone and pose potential risks. Therefore, a novel infrared ankle pump movement counter is designed. This product allows patients to perform voluntary dorsiflexion and plantarflexion movements and can check the accuracy of these movements, thus improving safety and the effectiveness of assisted exercise.

[0027] The following provides a detailed description of the structure and usage of the infrared ankle pump motion counter of this utility model:

[0028] An infrared ankle pump exercise counter includes two supports 1 and a flexible element 5 disposed between the two supports 1. The flexible element 5 can be an elastic rope or a spring. When using a spring, a corrugated tube can be installed on its surface to prevent the spring from pinching the skin. A connecting plate 4 is disposed between the two supports 1. The two ends of the connecting plate 4 are respectively locked to the bottom surface of the supports 1 by screws, thereby maintaining a relatively fixed distance between the two supports 1 to form a training area for the foot. The connecting plate 4 can be used to place the heel, while the forefoot can be supported on the flexible element 5, thereby allowing the body to voluntarily perform dorsiflexion and plantarflexion movements with the heel as the fulcrum.

[0029] The support frame 1 is equipped with an upper slide rail 131, a lower slide rail 132, and a counting circuit. The upper slide rail 131 and the lower slide rail 132 are respectively located at the upper and lower parts of the support frame 1. A back extension infrared sensor 2 is slidably mounted on the upper slide rail 131, with its sensing end facing the training area. It is used to sense whether the back extension movement is completed (the sensing position can be the toes, i.e., the big toe, or the highest arch of the instep at the final position of the movement). A plantar flexion infrared sensor 3 is slidably mounted on the lower slide rail 132, with its sensing end facing the training area. It is used to sense whether the plantar flexion movement is completed. Whether the movement is in place (the sensing position can be the toes of the foot at the final position of the movement, i.e., the big toe); in addition, both the dorsal extension infrared sensor 2 and the plantar flexion infrared sensor 3 are electrically connected to the counting circuit, which adopts a conventional counter of existing technology; when both the dorsal extension infrared sensor 2 and the plantar flexion infrared sensor 3 sense the corresponding part of the foot within one exercise cycle, the counter is triggered to obtain a count, so that the counting circuit completes one count, and represents the user completing a standard training movement, thereby realizing the checking of whether the movement is in place, which helps to improve the safety of use and improve the effect of assisted exercise.

[0030] It should be noted that the two supports 1 of this utility model are relatively independent during operation. The dorsiflexion infrared sensor 2 and plantarflexion infrared sensor 3 of the left support 1 are used to detect the standard of the dorsiflexion and plantarflexion movements of the left foot, while the dorsiflexion infrared sensor 2 and plantarflexion infrared sensor 3 of the right support 1 are used to detect the standard of the dorsiflexion and plantarflexion movements of the right foot. Therefore, the user can judge whether the training movements of the left and right feet are standard based on the counting of the two counting circuits, and can make targeted improvements and training.

[0031] In this embodiment, the bracket 1 includes a base 11, a support rod 12, and a support platform 13. The bottom end of the support rod 12 is disposed on the base 11, and the support platform 13 is disposed on the top end of the support rod 12. The dorsiflexion infrared sensor 2 and the plantarflexion infrared sensor 3 are respectively disposed on the upper and lower sides of the support platform 13. Therefore, by refining the structure of the bracket 1 and defining the positions of the dorsiflexion infrared sensor 2 and the plantarflexion infrared sensor 3, mainly because the upward dorsiflexion movement causes the toes and instep to move upward, while the downward plantarflexion movement causes the toes to move downward, the dorsiflexion infrared sensor 2 is disposed on the upper side, and the plantarflexion infrared sensor 3 is disposed on the lower side, which can better detect whether the dorsiflexion and plantarflexion movements are in place.

[0032] In this embodiment, the structures of the dorsal infrared sensor 2 and the plantar flexion infrared sensor 3 are as follows: The structures of the dorsal infrared sensor 2 and the plantar flexion infrared sensor 3 are identical. The dorsal infrared sensor 2 includes a sliding rod 21, a sliding member, and an infrared sensor 27. One end of the sliding rod 21 is slidably engaged with the upper slide rail 131. The sliding rod 21 is perpendicular to the horizontal plane. The sliding member is slidably connected to the sliding rod 21, and the sliding member slides along the length of the sliding rod 21. The infrared sensor 27 is mounted on the sliding member. Thus, by setting the sliding member, the infrared sensor 27 can move up and down to accommodate different foot sizes.

[0033] The sliding component includes a connecting block 23 and a bolt 26, as well as connecting pieces 24 disposed on opposite sides of the connecting block 23. The two connecting pieces 24 are bent and encircle the sliding rod 21. The ends of the two connecting pieces 24 overlap, and each end of the two connecting pieces 24 has a screw hole 25. The screw holes 25 of the two connecting pieces 24 are opposite to each other. The bolt 26 is threadedly connected to the two screw holes 25. The end of the bolt 26 abuts against the sliding rod 21 to restrict the sliding of the sliding component. Therefore, after the sliding component slides up and down to the desired position, the sliding component can be fixed by tightening the bolt 26.

[0034] In this embodiment, to improve the stability of the dorsal infrared sensor 2 and the plantar flexion infrared sensor 3 sliding on the upper and lower slide rails respectively, an upper frame 14 is provided on the top surface of the support platform 13. A space for the dorsal infrared sensor 2 to move is formed between the upper frame 14 and the support platform 13. The upper slide rail is opened on the top surface of the support platform 13. The upper frame 14 is provided with a first slide groove 141 corresponding to the upper slide rail. The first slide groove 141 allows the end of the sliding rod 21 to slide. Therefore, the sliding rod 21 can slide under the constraint of the upper slide rail and the first slide groove 141, thereby improving the sliding stability. Additionally, a lower frame 15 is provided on the bottom surface of the support platform 13. The lower frame 15 and the support platform 13 form a space for the plantar flexion infrared sensor 3 to move. A lower slide rail is provided on the bottom surface of the support platform 13. A second slide groove 151 is provided on the lower frame 15 corresponding to the lower slide rail. The second slide groove 151 allows the end of the sliding rod 21 to slide. Therefore, the sliding rod 21 can slide under the constraints of the lower slide rail and the second slide groove 151, thereby improving sliding stability.

[0035] To achieve automatic fixation of the dorsal extension infrared sensor 2 and the plantar flexion infrared sensor 3 after sliding, and to reduce interference caused by the position of the infrared sensors during training, a metal block 22 is provided at the end of the sliding rod 21 away from the upper or lower slide rail. The metal block 22 abuts against the top surface of the upper straddle 14 or the bottom surface of the lower straddle 15. Several magnetic blocks 16 are provided on the top surface of the upper straddle 14 and the bottom surface of the lower straddle 15. Several magnetic blocks 16 located on the upper frame 14 are located on one side near the first slide groove 141 and are evenly distributed along the extension direction of the first slide groove 141, covering the movement range of the metal block 22. Therefore, during the movement of the back extension infrared sensor 2, the metal block 22 can be fixed by attracting the corresponding magnetic block 16. Several magnetic blocks 16 located on the lower frame 15 are located on one side near the second slide groove 151 and are evenly distributed along the extension direction of the second slide groove 151, covering the movement range of the metal block 22. Therefore, during the movement of the plantar flexion infrared sensor 3, the metal block 22 can be fixed by attracting the corresponding magnetic block 16.

[0036] In this embodiment, a measuring ruler 17 is provided on the top surface of the upper frame 14 and the bottom surface of the lower frame 15. The measuring ruler 17 extends along the length of the upper or lower slide rail, which makes it easier for the user to determine the standard distance to be measured when using it for different patients, thus helping to improve the efficiency of use.

[0037] Based on the above description of the structure of the infrared ankle pump motion counter of this utility model, the following further describes the usage method of the infrared ankle pump motion counter:

[0038] How to use the infrared ankle pump motion counter:

[0039] ① The patient wears a lower limb venous blood velocity monitoring wearable device at the ankle. This wearable device can be modified from a venous blood flow velocity monitoring watch and is connected to a mobile phone via Bluetooth to monitor the venous blood velocity in the lower limb in real time. When the venous blood flow velocity is lower than the lower limit of the normal value, an alarm will be issued to remind the patient to perform ankle pump exercises, etc.

[0040] ② Place the infrared ankle pump counter on a horizontal surface and activate the dorsal extension infrared sensor 2 and the plantar flexion infrared sensor 3;

[0041] ③ The patient lies flat on a horizontal surface, then places both feet in the training area, with the heels supporting the foot on the connecting pad 4 and the forefoot resting on the flexible component 5. Using the heels as a fulcrum, the patient performs dorsiflexion and plantarflexion movements before training. During dorsiflexion and plantarflexion movements, the positions of the infrared sensors 27 in the dorsiflexion infrared sensor 2 and the plantarflexion infrared sensor 3 are adjusted so that when the standard dorsiflexion movement reaches its final position, the dorsiflexion infrared sensor 2 can sense the instep or toe (thumb), and when the standard plantarflexion movement reaches its final position, the plantarflexion infrared sensor 3 can sense the toe (thumb).

[0042] ④ Complete a specified number of sets of dorsiflexion and plantarflexion movements according to the training intensity requirements. The validity of this number is determined by the counting circuit, thereby completing a complete set of training movements.

[0043] In summary, this invention, by incorporating a flexible element 5 between two supports 1, facilitates voluntary dorsiflexion and plantarflexion movements by the patient. Simultaneously, adjustable dorsiflexion infrared sensors 2 and 3 are installed on the supports 1 to detect the standardization of these movements, verifying whether the dorsiflexion and plantarflexion actions are performed correctly. When the detection standard is met, a counting circuit is triggered to complete one exercise cycle, allowing the patient to self-check whether the training movements have met the standards. Compared to existing technologies that use electric mechanical assistance to complete movements, where mechanical movement is relatively fixed, this invention's infrared ankle pump motion counter relies primarily on the patient's voluntary completion of training movements, thus improving safety and the effectiveness of assisted exercise.

[0044] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, using ordinary technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, this utility model can also be modified, replaced or combined in various other forms, all of which fall within the scope of protection of this utility model.
