Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and particularly relates to an insole based on plantar skin grafting. Background Art

[0002] Plantar skin grafting usually refers to taking skin from the patient's own plantar surface and then transplanting it to other parts of the body to treat skin defects caused by burns, trauma or other reasons. Due to its unique abrasion resistance and pressure resistance, it has gradually begun to be used in the repair of areas that need to withstand high friction and pressure, especially those areas that need to withstand high friction and pressure. After such surgery, correct rehabilitation care is crucial.

[0003] In the prior art, some custom insoles need to generate a static model through 3D scanning or medical imaging, but they cannot adapt to the daily changes in foot shape and the rehabilitation process. For example, the patent with the publication number CN112861410B discloses an orthotic insole manufacturing method based on medical images, which mainly models based on medical images and manufactures orthotic insoles in combination with finite element analysis. However, it lacks the ability of dynamic adjustment, resulting in possible decline in the adaptability of the insole during long-term use.

[0004] In summary, how to solve the problem that the custom insoles in the prior art lack the ability of dynamic adjustment, resulting in possible decline in the adaptability of the insole during long-term use has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose an insole based on plantar skin grafting. Summary of the Invention

[0005] To solve the above problems, the present invention provides an insole based on plantar skin grafting. By real-time monitoring the pressure distribution on the sole of the foot and using the design of the inflatable component, it can simulate the principle of clinical compression therapy, dynamically adjust the pressure gradient during walking, and maintain natural motion feedback, thereby further improving the adaptability of long-term wearing.

[0006] To achieve the above object, the technical solution of the present invention is as follows: An insole based on plantar skin grafting, including an insole body located above the sole of the shoe. A flexible layer is fixedly connected to the top of the sole of the shoe, and an adjusting component for adjusting the support height of the insole body is arranged inside the insole body.

[0007] The adjusting component includes a controller, an adjusting layer and a sensing layer. The sensing layer is fixedly connected to the top of the adjusting layer, and the adjusting layer is located above the flexible layer. A number of pressure sensors are arranged in an array inside the sensing layer, and a number of airbags are arranged in an array inside the adjusting layer. Adjacent airbags are all interconnected, and the connection points of adjacent airbags are all connected to a solenoid valve. The controller is used to receive the pressure information sent by the pressure sensors and control the opening and closing of the solenoid valves based on the pressure information.

[0008] On both sides of the insole body in the length direction, there are fixing components for fixing the insole body.

[0009] On both sides of the flexible layer in the length direction, there are inflation components for inflating the airbag; the fixing components are used to drive the inflation components to move.

[0010] The technical principle of the above solution is as follows:

[0011] The pressure distribution of different parts of the sole is obtained through several pressure sensors built in the sensing layer. According to the different force conditions of different parts of the user during walking, the opening and closing of the corresponding solenoid valves are opened, and the support height of the adjustment layer in different parts is adjusted, so as to provide pressure support for the area after skin grafting on the sole, making the local scar ischemic, thereby reducing scar hyperplasia in the skin grafting area. The fixing component can fix the insole body on the sole, reducing the occurrence of displacement of the insole body; the design of the inflation component can provide a support source for the inside of the airbag, enabling the airbag to adjust the support height for different parts of the sole.

[0012] The above solution has the following beneficial effects:

[0013] 1. Compared with the existing technology that uses a fixed support height and inclination, by real-time monitoring the pressure distribution of the sole, the airbags in different parts can be lifted by adjusting the opening and closing of the corresponding solenoid valves, so as to targetedly adjust the support height of each part of the insole body, control the local ischemic state, such as reducing the blood supply in the scar area; thus, it can effectively inhibit the excessive proliferation of fibroblasts, reduce the risk of scar hyperplasia, and reduce the impact on the user's walking in shoes in the later stage.

[0014] 2. Compared with the existing devices that cannot be adjusted in real time according to the user's gait cycle, using the design of the inflation component, it can simulate the principle of clinical compression therapy, dynamically adjust the pressure gradient during walking, promote scar tissue remodeling, and shorten the rehabilitation cycle. The support height of the insole body deforms in real time with the gait cycle, increasing the local pressure while maintaining natural movement feedback, reducing the risk of compensatory gait, and further improving the adaptability of long-term wearing.

[0015] 3. Compared with the existing insoles that are fixed on the sole using simple adhesives or friction, through the design of the fixing component, the close fit between the insole body and the sole is ensured, reducing the relative sliding during movement, and effectively improving gait stability.

[0016] Furthermore, the fixing component includes a frustum of a cone with a trapezoidal cross-section, a connecting rod, and a plurality of sliding blocks, and the sliding blocks are all slidably fitted inside the side wall of the adjusting layer; the connecting rod is fixedly connected to the top of the shoe sole, and the top end of the connecting rod penetrates through the insole body and is fixedly connected to the frustum of a cone; one side of the sliding block close to the frustum of a cone is inclined. A pushing component for ejecting the sliding block is arranged inside the side wall of the sensing layer.

[0017] Beneficial effects: Through the design of the trapezoidal frustum of a cone and the inclined surface of the sliding block, the sliding block can be squeezed into the side wall of the insole body during the process of pressing the insole body, and the pushing component can push out the sliding block, so that the sliding block is engaged with the bottom of the frustum of a cone, thereby enabling the insole body to be effectively fixed and further increasing its stability.

[0018] Furthermore, the pushing component includes a plurality of cross bars and a clamping plate. One end of each cross bar is fixedly connected to the side of the sliding block away from the frustum of a cone; the other ends of the cross bars are fixedly connected to the clamping plate; a first spring is sleeved outside each cross bar, and the two ends of the first spring are respectively fixedly connected to the sliding block and the side wall of the adjusting layer.

[0019] Beneficial effects: Since the two ends of the cross bar are respectively fixedly connected to the clamping plate and the sliding block, and the two ends of the first spring are respectively fixedly connected to the sliding block and the adjusting layer; the sliding block can rebound towards the frustum of a cone through the elastic force of the first spring, thereby pushing the sliding block out of the side wall of the insole body.

[0020] Furthermore, the inflation component includes a piston cylinder, a piston rod, and a piston plate. The piston cylinder is embedded and installed inside the side wall of the flexible layer; the piston plate is slidably fitted with the inner side wall of the piston cylinder, and the piston rod is fixedly connected to the top of the piston plate.

[0021] The bottom of the piston cylinder is communicated with an input pipe and an output pipe, and one-way valves are communicated at the connection parts of the input pipe and the output pipe with the piston cylinder; one end of the input pipe away from the piston cylinder is communicated to the outside of the flexible layer, and one end of the output pipe away from the piston cylinder is communicated with the inside of the airbag.

[0022] A transmission component for driving the piston rod to reciprocate is arranged at the bottom of the sliding block.

[0023] Beneficial effects: The piston rod is driven to reciprocate by the transmission component, and the piston rod drives the piston plate to reciprocate inside the piston cylinder. When the piston plate reciprocates, suction and thrust can be generated. When suction is generated, the gas outside the flexible layer can be sucked into the piston cylinder, and when thrust is generated, the gas inside the piston cylinder is transmitted to the airbag, thereby realizing the inflation of the inside of the airbag.

[0024] Further, the transmission assembly includes a top block, a second spring, and a plurality of ejector rods. The top block is slidably fitted on the outer wall of the connecting rod; the ejector rods are all fixedly connected to the bottom of the sliding block, and the bottom ends of the ejector rods are in contact with the top block; one end of the piston rod away from the piston plate is fixedly connected to the outer wall of the top block; a sliding groove for the top block to slide is formed in the flexible layer, and the two ends of the second spring are respectively fixedly connected to the top block and the sole.

[0025] On both sides in the length direction of the flexible layer, a limit releasing assembly is further provided for releasing the ejection of the sliding block.

[0026] Beneficial effects: Since the top block is slidably fitted on the outer wall of the connecting rod, and the two ends of the second spring are respectively fixedly connected to the top block and the sole, during the walking process of the user, the ejector rods can continuously press the top block, so that the top block moves downward, and then the top block drives the piston rod to move synchronously. The design of the second spring can lift the top block and push the sliding block to contact the frustum, reducing the occurrence of its slipping out.

[0027] Further, the limit releasing assembly includes telescopic rods fixedly connected to the outside of the flexible layer. A plurality of stay wires are fixedly connected to the top ends of the telescopic rods, and the ends of the stay wires away from the telescopic rods are all fixedly connected to the clamping plate.

[0028] Beneficial effects: By pressing the two side regions of the insole body, since the telescopic rods are fixedly connected with the stay wires, and the other ends of the stay wires are fixedly connected to the clamping plate, the sliding block can be driven to slide out to the outside of the frustum by pressing the telescopic rods through the stay wires, so that the insole body can be disassembled.

[0029] Further, air pressure sensors are fixedly connected to the inner walls of the air bags, and the controller is used to receive and store the air pressure information sent by the air pressure sensors.

[0030] Beneficial effects: The air pressure sensors can effectively monitor the air pressure information inside the air bags. Combining with the induction of the plantar pressure by the induction layer can further improve the accuracy of collecting the plantar contact pressure information.

[0031] Further, the air bags are also connected with exhaust valves, and the controller is used to control the opening and closing of the exhaust valves based on the air pressure information.

[0032] Beneficial effects: Through the design of the exhaust valves, when the air pressure sensors detect that the gas inside the air bags exceeds the limit, the excess gas inside the air bags can be discharged, and the gas generated by the air bags can be used to dissipate heat for the plantar, which is beneficial to maintaining a dry environment for the plantar after skin grafting and accelerating its recovery speed.

[0033] Further, it further includes a monitoring and adjusting system for assisting in monitoring and adjusting the support height of the insole body. The monitoring and adjusting system includes the following modules:

[0034] An information collection module, which is used to collect the pressure distribution information of the sole under different gaits and transmit the pressure distribution information to the data analysis module.

[0035] A data analysis module, which is used to receive the pressure distribution information transmitted by the information collection module, analyze the gait characteristics, stress distribution and current posture of the user based on the pressure distribution information, and output the analysis result of the pressure distribution information.

[0036] An intelligent adjustment module, which is used to adjust the support height and tilt angle of the insole body according to the analysis result analyzed by the data analysis module.

[0037] Beneficial effects: By capturing the pressure changes of each part of the sole through the information collection module, deeply analyzing the gait characteristics and pressure distribution of the user, identifying potential problem areas, and providing support adjustment schemes with different heights; the intelligent adjustment module can dynamically adjust the height and tilt of each part of the insole body according to the gait characteristics and pressure distribution of the user to ensure effective support in various situations. And for the area after skin grafting on the sole, by adjusting the support height of this area, pressure is generated on this area, making this area ischemic and reducing the risk of scar hyperplasia.

[0038] Furthermore, the data analysis module also analyzes based on the user's individual differences, health status and rehabilitation progress, and establishes a personalized data analysis model.

[0039] Beneficial effects: By establishing a personalized data analysis model, it is ensured that each user can obtain the support height and tilt angle suitable for their specific situation, thereby improving comfort and rehabilitation effect. And it can dynamically adjust the height and tilt of each part of the insole in real time according to the gait changes and rehabilitation progress of the user to ensure the best support effect for the user at each stage.

[0050] Fixing assemblies for fixing the insole body 1 are provided on both sides in the length direction of the insole body 1.

The sides of the sliding blocks 7 close to the frustum 5 are all inclined.

[0051] An ejecting assembly for ejecting the sliding blocks 7 is provided inside the side wall of the induction layer. The ejecting assembly includes a number of cross bars 8 and a clamping plate 9. One ends of the cross bars 8 are all fixedly bonded to the sides of the sliding blocks 7 away from the frustum 5. The other ends of the cross bars 8 are all fixedly bonded to the clamping plate 9. First springs 10 are sleeved outside the cross bars 8, and both ends of the first springs 10 are fixedly bonded to the sliding blocks 7 and the side wall of the adjusting layer respectively.

[0052] Inflating assemblies for inflating the airbags 3 are provided on both sides in the length direction of the flexible layer 2; the fixing assembly is used to drive the inflating assembly to move.

[0053] The inflating assembly includes a piston cylinder 11, a piston rod 12, and a piston plate 13. The piston cylinder 11 is embedded and installed inside the side wall of the flexible layer 2. The piston plate 13 is slidably fitted with the inner side wall of the piston cylinder 11, and the piston rod 12 is fixedly bonded to the top of the piston plate 13.

[0054] The bottom of the piston cylinder 11 is connected with an input pipe and an output pipe, and the connection points between the input pipe and the output pipe and the piston cylinder 11 are connected with a one-way valve; the other end of the input pipe is connected to the outside of the flexible layer 2, and the other end of the output pipe is connected to the inside of the airbag 3.

[0055] A transmission assembly for driving the piston rod 12 to reciprocate is provided at the bottom of the sliding block 7. The transmission assembly includes a top block 14, a second spring 15 and a plurality of top rods 16. The top block 14 is slidably matched with the outer wall of the connecting rod 6; the top rods 16 are integrally formed at the bottom of the sliding block 7, and the bottom ends of the top rods 16 are in contact with the top block 14; one end of the piston rod 12 away from the piston plate 13 is fixedly bonded to the outer wall of the top block 14; a sliding groove for the top block 14 to slide is provided in the flexible layer 2, and the two ends of the second spring 15 are fixedly bonded to the top block 14 and the sole, respectively.

[0056] The flexible layer 2 is provided with a release assembly on both sides of the length direction for releasing the sliding block 7. The release assembly includes a telescopic rod 17 fixedly bonded to the outside of the flexible layer 2, and the top of the telescopic rod 17 is fixedly sleeved with a pull wire, and the other end of the pull wire is fixedly sleeved with the card plate 9.

[0057] The specific implementation process is as follows:

[0058] First, the flexible layer 2 is fixed and bonded to the sole by Velcro, and the pressure distribution of different parts of the sole is obtained by using a plurality of pressure sensors 4 built into the sensing layer. According to the different stress conditions of different parts of the user when walking, the corresponding solenoid valves are opened and closed, and the support height of the adjustment layer in different parts is adjusted, so as to provide pressure support for the area after skin grafting on the sole of the foot, so as to make the local scar ischemic, thereby reducing the scar hyperplasia after the skin grafting area.

[0059] Combination Figure 3 As shown, since the two ends of the cross bar 8 are fixedly bonded to the clamping plate 9 and the sliding block 7 respectively, and the two ends of the first spring 10 are fixedly bonded to the sliding block 7 and the adjustment layer respectively; therefore, the elastic force of the first spring 10 enables the sliding block 7 to rebound to one side of the truncated table 5, thereby pushing the sliding block 7 out of the side wall of the insole body 1.

[0060] Through the design of the trapezoidal truncated cone 5 and the inclined surface of the sliding block 7, the sliding block 7 can be squeezed into the side wall of the insole body 1 during the pressing process of the insole body 1, and the sliding block 7 can be pushed out by the first spring 10, so that the sliding block 7 is engaged with the bottom of the truncated cone 5, so that the insole body 1 can be effectively fixed, further increasing its stability.

[0061] Combination Figure 3As shown, since the top block 14 is slidably fitted to the outer wall of the connecting rod 6 and the two ends of the second spring 15 are fixedly bonded to the top block 14 and the sole respectively, it can squeeze the adjustment layer during the user's walking process, thereby squeezing the sliding block 7 to move downward. When the sliding block 7 moves downward, it drives the ejector rod 16 to move downward synchronously. Furthermore, the ejector rod 16 is continuously used to press the top block 14, causing the top block 14 to move downward, thereby driving the piston rod 12 to move synchronously by using the top block 14. The design of the second spring 15 can lift the top block 14 and push the sliding block 7 to contact the frustum 5, reducing the occurrence of its slipping out.

[0062] When the piston rod 12 moves, it drives the piston plate 13 to reciprocate in the piston cylinder 11. When the piston plate 13 reciprocates, it can generate suction and thrust. When generating suction, it can suck the gas outside the flexible layer 2 into the piston cylinder 11, and when generating thrust, it transmits the gas inside the piston cylinder 11 to the airbag 3, thereby realizing the inflation of the inside of the airbag 3.

[0063] By pressing the two side regions of the insole body 1, since the telescopic rod 17 is fixedly sleeved with a number of guy wires, and the other ends of the guy wires are fixedly sleeved with the clamping plate 9, it is possible to drive the sliding block 7 to slide out of the frustum 5 by pressing the telescopic rod 17 through the guy wires, so that the insole body 1 can be disassembled. In this embodiment, the telescopic rod 17 cannot be touched by the sole of the foot when the user walks.

[0064] In the prior art, some customized insoles are made by finite element analysis, which lack the ability to dynamically adjust the sole of the foot. In this embodiment, by real-time monitoring the pressure distribution of the sole of the foot, the airbags 3 at different positions can be propped up by adjusting the opening and closing of the corresponding solenoid valves, thereby targeting the adjustment of the support height of each part of the insole body 1 and controlling the local ischemic state, such as reducing the blood supply in the scar area; thereby effectively inhibiting the excessive proliferation of fibroblasts and reducing the risk of scar hyperplasia, thus reducing the impact on the user's shoe wearing and walking in the later stage.

[0065] Using the design of the piston plate 13 and the piston rod 12 to simulate the principle of clinical compression therapy, dynamically adjust the pressure gradient during walking, promote scar tissue remodeling, and shorten the rehabilitation period. The support height of the insole body 1 deforms in real time with the gait cycle. While increasing the local pressure, it maintains natural motion feedback, reduces the risk of compensatory gait, and further improves the adaptability of long-term wearing. Through the design of the sliding block 7 and the first spring 10, the tight fit between the insole body 1 and the sole is ensured, reducing their relative sliding during movement, and effectively improving gait stability.

[0066] Embodiment 2:

[0067] The difference from the above embodiment is that a pressure sensor is fixedly bonded to the inner wall of each airbag 3, and the controller is used to receive and store the air pressure information sent by the pressure sensor.

[0068] The specific implementation process is as follows: The air pressure sensor can effectively monitor the air pressure information inside the airbag 3. Combining with the induction of the sole pressure by the induction layer can further improve the accuracy of collecting the sole contact pressure information.

[0069] Embodiment 3:

[0070] The difference from the above embodiment is that the airbag 3 is also connected with an exhaust valve, and the controller is used to control the opening and closing of the exhaust valve based on the air pressure information.

[0071] The specific implementation process is as follows: Through the design of the exhaust valve, when the air pressure sensor detects that the gas inside the airbag 3 exceeds the limit, the excess gas inside the airbag 3 can be discharged, and the gas generated by the airbag 3 can be used to dissipate heat from the sole, which is beneficial to maintaining a dry environment after skin grafting on the sole and accelerating its recovery speed.

[0072] Embodiment 4:

[0073] As shown in the appendix Figure 4 The difference from the above embodiment is that this embodiment also provides a monitoring and adjustment system for assisting in monitoring and adjusting the support height of the insole body 1. The monitoring and adjustment system includes an information collection module for collecting sole pressure information, a data analysis module for analyzing pressure distribution information, and an intelligent adjustment module for adjusting the support height and inclination of the insole body 1.

[0074] The functions of each module are introduced as follows:

[0075] The information collection module is used to collect the pressure distribution information of the sole under different gaits (such as the calcaneal region, metatarsal head region, and arch region, etc.), and transmit the pressure distribution information to the data analysis module.

[0076] The data analysis module is used to receive the pressure distribution information transmitted by the information collection module, analyze the gait characteristics (such as metatarsal angle or arch index), stress distribution, and current posture (such as standing, walking, or sitting and lying, etc.) of the user based on the pressure distribution information, and output the analysis result of the pressure distribution information. The data analysis module also analyzes based on the individual differences of the user (such as weight, height, and age, etc.), health status, and rehabilitation progress, and establishes a personalized data analysis model. In this embodiment, machine learning algorithms are used for data analysis, preferably the CNN neural network algorithm.

[0077] The intelligent adjustment module is used to adjust the support height and inclination angle of the insole body 1 according to the analysis result analyzed by the data analysis module. For example, in the early stage after skin grafting on the sole, the support height of the arch part is increased to increase the pressure on the transplanted skin and reduce the occurrence of scar hyperplasia; as the rehabilitation progresses, the support height is gradually reduced to restore the normal gait.

[0078] The specific implementation process is as follows: The information collection module captures the pressure changes of various parts of the sole, deeply analyzes the user's gait characteristics and pressure distribution, identifies potential problem areas, and provides support adjustment solutions with different heights; the intelligent adjustment module can dynamically adjust the height and inclination of each part of the insole body 1 according to the user's gait characteristics and pressure distribution to ensure effective support in various situations. And for the area where skin is taken from the sole, by adjusting the support height of this area, pressure is generated on this area, making this area ischemic and reducing the risk of scar hyperplasia.

[0079] By establishing a personalized data analysis model, it is ensured that each user can obtain the support height and inclination angle suitable for their specific situation, thereby improving comfort and rehabilitation effect. And it can dynamically adjust the height and inclination of each part of the insole in real time according to the user's gait changes and rehabilitation progress to ensure the best support effect for the user at each stage.

[0080] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
