Description

Technical Field

[0001] The invention relates to the field of ankle joint treatment, in particular to an ankle joint rehabilitation testing device. Background Art

[0002] Ankle rehabilitation testing devices are devices used to treat and rehabilitate ankle injuries or diseases. These devices can assist patients in effective rehabilitation and improve ankle function and stability.

[0003] Rehabilitation testing devices can include a variety of different equipment, such as ankle rehabilitation devices, rehabilitation mats, elastic resistance bands, weight machines, etc. These devices can promote rehabilitation in different ways, such as by improving the range of motion of the joint, increasing muscle strength, improving balance and coordination, etc. The design of ankle rehabilitation testing devices can be customized according to the specific needs and condition of the patient. Some devices may focus on improving the range of motion of the joint through progressive movements and stretching; while other devices may focus more on increasing muscle strength and performing rehabilitation through resistance.

[0004] At present, most rehabilitation test devices on the market use cylinders or motors as power sources to drive the patient's feet to swing up and down, but do not rely on the patient's own strength to move autonomously. The patient is always in a passive rehabilitation mode. Although it can help restore the range of motion of the joints, it has limited effect on enhancing muscle strength. Therefore, it does not meet existing needs. In response to this, we have proposed an ankle joint rehabilitation test device. Summary of the invention

[0018] As an optional solution of the ankle joint rehabilitation testing device described in the present invention, wherein: the limiting strip is configured as an elastic strip.

[0019] The present invention has the following beneficial effects:

[0020] 1. The ankle joint rehabilitation test device, through the cooperation of the air supply pipe, the piston block and the push rod, when the patient's sole presses the first airbag, the gas reaches the inside of the push groove through the air supply pipe, and the gas will push the piston block, so that the piston block drives the push rod to move, and the sliding block is used to resist the sliding seat during the movement. Since the sliding seat is arranged on the upper side of the first plate, the first plate rotates with the connecting rod as the center of the circle during the movement of the piston block, so that the first plate is tilted, so the tilted first plate shortens the space for the foot to move, and when the patient's toes move downward, the tilted first plate applies a resistance force to the front pedal and increases the resistance of rehabilitation. In addition, the difficulty of rehabilitation is adjusted by the patient's strength of pressing the first airbag. When the patient presses the first airbag with less force, the increased resistance is also small. Similarly, when the patient presses the first airbag with greater force, the increased resistance is also large, so that the patient can adjust the intensity of rehabilitation according to his own strength and comfort, so as to better adapt to the different states of the patient. In addition, as the patient's strength increases, they can gradually increase the pressing force, thereby gradually increasing the difficulty of rehabilitation and achieving progressive rehabilitation.

[0021] 2. The ankle joint rehabilitation test device, through the cooperation of the second support tube, the reinforcing rod, the connecting pipe and the connecting pipe, when the patient presses the first airbag harder, the gas pushes the piston block, and the connecting pipe is connected to the air outlet, so that the gas reaches the inside of the second support tube through the connecting pipe, and at the same time pushes the reinforcing rod, so that the reinforcing rod pushes the first plate. Since the reinforcing rod is located in the middle of the first plate, the deformation generated when pushing the upper end of the first plate is smaller than the middle end for the same pushing distance, so that the inclination angle of the first plate is large, thereby greatly reducing the space for the foot to move, thereby increasing the resistance to the foot movement, and by controlling the degree of deformation at different positions of the first plate, the size of the resistance can be adjusted, so that the patient can adjust the rehabilitation intensity according to his own strength and comfort.

[0022] 3. The ankle joint rehabilitation test device, through the cooperation of the limiting bar, the first gear, the driving ring and the tooth block, when the toes fall from the lifted state, the placement seat drives the connecting shaft to rotate, and because the tooth block is engaged with the side with the smaller tooth socket angle, the rotation shaft is driven to rotate during the downward movement of the placement seat, and at the same time, by utilizing the cooperation of the first gear and the limiting bar, during the rotation of the first gear, the first gear continuously resists the limiting bar, and the limiting bar continuously engages with the first gear, so the limiting bar is always in a state of engaging and disengaging with the first gear, thereby reducing the rotation speed of the connecting shaft and limiting the descending speed of the placement seat; by limiting the descending speed, the risk of the patient's foot being injured due to a sudden fall is reduced as much as possible. Moreover, through the cooperation of the limiting bar and the first gear, a certain resistance can be added to the patient's toes when they move downward, thereby helping rehabilitation.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is intended to promote the solution of the problem that most rehabilitation test devices on the market use cylinders or motors as power sources to drive the patient's feet to swing up and down, but do not rely on the patient's own strength to move autonomously, always putting the patient in a passive rehabilitation mode. Although it can help restore the range of motion of the joints, it has limited effect on strengthening muscle strength. Please refer to Figure 1-Figure 9, an ankle joint rehabilitation testing device, comprising a support plate 110 and a support frame 111 movably mounted on the side of the support plate 110, a placement seat 120 for placing a limb rotatably mounted on the support frame 111, the placement seat 120 comprising a front pedal 121 and a rear pedal 122, a support seat 130 mounted on the support plate 110, a pressing plate 131 for assisting rehabilitation mounted inside the support seat 130, an end of the front pedal 121 slidably cooperates with the pressing plate 131, a pushing mechanism 140 for controlling the deformation of the pressing plate 131 is mounted inside the support seat 130, and a first airbag 112 for driving the pushing mechanism 140 to operate is mounted on the front pedal 121;

[0035] The pushing mechanism 140 includes a pushing rod 141 slidably mounted inside the supporting seat 130 , a sliding seat 142 mounted on the pressing plate 131 , and a sliding block 143 slidably mounted inside the sliding seat 142 . The sliding block 143 is hinged to the end of the pushing rod 141 .

[0036] See Figure 1 , Figure 3 In specific implementation, when the patient is doing rehabilitation, he needs to place his feet on the support seat 130. However, the operator can adjust the resistance by the force of the sole of the foot stepping on the support seat 130 during the process of placing the feet, so that the operator can adjust the resistance during rehabilitation according to his own situation. Therefore, when the patient places the feet, the support seat 130 needs to be pressed. When the patient's toes move downward, the sole of the foot will press the first airbag 112. The resistance of rehabilitation is adjusted by the force of the sole pressing. When the force of the sole pressing is small, the descending distance of the first airbag 112 is shorter, and when the force of the sole pressing is large, the descending distance of the first airbag 112 is longer.

[0037] A connecting seat 150 is installed on the support plate 110, and a support rod 151 is hinged on the connecting seat 150. A sliding rod 152 is installed on the bottom side of the front pedal 121, and the sliding rod 152 slides inside the support rod 151. The pressing plate 131 includes a first plate 132 and a second plate 133. A connecting rod 230 is installed inside the support seat 130. The first plate 132 and the second plate 133 are both rotatably engaged on the connecting rod 230. A one-way torsion spring 134 is installed between the first plate 132 and the connecting rod 230. The second plate 133 has the same specifications as the first plate 132. The setting of the one-way torsion spring 134 allows the first plate 132 and the second plate 133 to be smoothly reset.

[0038] A first support tube 160 is installed inside the support seat 130, an air inlet groove 161 is opened in the inner wall of the support seat 130, a push groove 162 is installed inside the first support tube 160, the push groove 162 is communicated with the air inlet groove 161, a piston block 163 is installed inside the push groove 162, a push rod 141 is installed on the side of the piston block 163, an annular block 164 is installed inside the push groove 162, a first spring 165 is installed between the annular block 164 and the piston block 163, a sliding groove 170 is opened inside the sliding seat 142, the sliding block 143 slides and engages with the sliding groove 170, so that when the first plate 132 is tilted, the sliding block 143 can adaptively adjust its height.

[0039] See Figure 1 , Figure 2 , Figure 3 and Fig. 9 In a specific implementation, when the sole of the foot presses the first airbag 112, the gas squeezed inside the first airbag 112 will reach the inside of the support seat 130 through the air delivery pipe 114, and reach the inside of the push groove 162 through the cooperation of the air inlet groove 161. In the process of the gas continuously entering the push groove 162, the gas pushes the piston block 163, so that the piston block 163 is displaced, and drives the push rod 141 to move forward during the displacement. In the process of the push rod 141 moving forward, it resists the sliding block 143, so that the sliding block 143 is subjected to pressure and the sliding seat 142 is pushed. Since the sliding seat 142 is arranged on the upper side of the first plate 132, the sliding seat 142 is driven to rotate with the connecting rod 230 as the center during the force applied to the first plate 132, so that the first plate 132 is driven to rotate with the connecting rod 230 as the center. One plate 132 is tilted, so that the tilted first plate 132 shortens the space for the foot to move. Therefore, when the patient's toes move downward, the first plate 132 resists the front pedal 121, exerting resistance on the movement of the patient's toes; when the patient presses the first airbag 112 with little force, the extension of the push rod 141 is relatively small, the tilt angle of the first plate 132 is also small, and the increased resistance is also small. Similarly, when the patient presses the first airbag 112 with great force, the increased resistance is also great. The resistance is increased by pressing the first airbag 112 with the sole of the patient's foot, so that the patient can adjust the pressing force according to his or her own strength and comfort. Not only that, as the patient's strength increases, they can gradually increase the pressing force, thereby gradually increasing the difficulty of rehabilitation and achieving progressive rehabilitation.

[0040] Embodiment 2: This embodiment is intended to solve the problem that when the patient presses with greater force, the angle of the first plate 132 changes relatively little, resulting in a small increase in resistance, thus affecting recovery. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 9A second support tube 180 is installed inside the support seat 130, a reinforcing rod 181 is slidably installed inside the second support tube 180, a second spring 182 is installed between the reinforcing rod 181 and the second support tube 180, a connecting pipe 183 is opened between the piston block 163 and the push rod 141, an air outlet 184 is opened on the first support tube 160, an air inlet 185 is installed on the second support tube 180, a connecting pipe 186 is installed between the air inlet 185 and the air outlet 184, a third spring 113 is installed inside the first airbag 112, and an air delivery pipe 114 is installed between the first airbag 112 and the air inlet groove 161;

[0041] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In a specific implementation, when the patient presses the first airbag 112 harder, the gas pushes the push rod 141 to move. During the movement of the push rod 141, the connecting pipe 183 is connected to the air outlet 184, so that the gas reaches the inside of the second support tube 180 through the cooperation of the connecting pipe 183, the air outlet 184 and the connecting pipe 186, and pushes the reinforcing rod 181, so that the reinforcing rod 181 pushes the first plate 132 during the movement. Since the reinforcing rod 181 is located in the middle of the first plate 132, for the same pushing distance, the deformation generated when pushing the upper end of the first plate 132 is smaller than that of the middle end, thereby increasing the angle of inclination of the first plate 132, thereby greatly reducing the space for the foot to move, thereby increasing the resistance to the foot movement.

[0042] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In a specific implementation, a second airbag 115 is installed on the rear pedal 122, and the diameter of the first airbag 112 is larger than that of the second airbag 115. Two air inlet grooves 161 are provided, and the first airbag 112 and the second airbag 115 are respectively connected to the two air inlet grooves 161. Usually, people are more relaxed when their toes move downward, and it is more strenuous to lift their toes upward. Therefore, the diameter of the first airbag 112 is larger than that of the second airbag 115, so the capacity of the gas is also small, and thus the gas inside is relatively small. Therefore, after the patient presses the second airbag 115, the degree of influence of the gas on the push rod is also limited, so that the space for the second plate 133 to tilt is also limited, thereby reducing the resistance when the toes move upward.

[0043] Embodiment 3: This embodiment is intended to help solve the problem that when a patient tries to lift his toes during rehabilitation, his toes may be quickly reset due to insufficient strength or improper control, and secondary injury to the ankle may be caused by gravity. This embodiment is an improvement based on Embodiment 2. For details, please refer to Figure 1-Figure 9 A connecting shaft 190 is rotatably mounted on the side of the support frame 111, and the connecting shaft 190 is fixedly connected to the placement seat 120. A limiting box 191 is mounted on the support frame 111, and a rotating shaft 192 is rotatably mounted inside the limiting box 191. A first gear 193 and a connecting ring 194 are mounted on the rotating shaft 192, and a tooth groove 195 is provided on the side of the connecting ring 194. A movable rod 210 is rotatably mounted on the connecting shaft 190, and driving rings 211 are mounted on both ends of the movable rod 210. A connecting block 212 is mounted on the side of the driving ring 211, and a tooth block 213 is integrally provided on the bottom side of the connecting block 212, and the tooth block 213 is engaged with the tooth groove 195. Restriction bars 220 are symmetrically mounted inside the limiting box 191, and the restriction bars 220 are configured as elastic bars, and the two restriction bars 220 are engaged with the first gear 193;

[0044] See Figure 6 and Figure 7 In a specific implementation, when the patient's toes move downward from the lifted state, the patient's legs will drive the placement seat 120 and the support frame 111 to rotate. Therefore, the placement seat 120 drives the connecting shaft 190 to rotate during its rotation. During the rotation of the connecting shaft 190, the tooth block 213 is engaged with the tooth groove 195. At the same time, the tooth of the tooth groove 195 has a smaller inclination angle on one side and a larger inclination angle on the other side. During the downward movement of the placement seat 120, the tooth block 213 is engaged with the side with a smaller angle of the tooth groove 195, thereby driving the rotating shaft 192 to rotate. At the same time, the rotating shaft 192 drives the tooth block 213 to engage with the tooth groove 195. The first gear 193 is driven to rotate. When the first gear 193 rotates, the first gear 193 contacts the limiting bar 220, causing the limiting bar 220 to retract and disengage from the first gear 193. As the first gear 193 continuously rotates, the limiting bar 220 is continuously engaged with or disengaged from the first gear 193, thereby reducing the rotation speed of the connecting shaft 190 and limiting the descending speed of the placement seat 120. Moreover, through the cooperation of the limiting bar 220 and the first gear 193, when the patient's toes move downward, a certain resistance can be added to it to help recovery.

[0045] See Figure 6 and Figure 7 It should be noted that the first gear 193 is configured as a ratchet. Since the first gear 193 can only rotate in one direction, when the patient's toes drive the placement seat 120 to move upward, the tooth block 213 is engaged with the side with a larger angle with the tooth groove 195. Since the first gear 193 can only rotate in one direction, it is restricted by the first gear 193, so that the tooth block 213 and the tooth groove 195 are misaligned and slidably matched, thereby not driving the first gear 193 to rotate, and therefore will not affect the lifting of the patient's toes.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
