Description

Technical Field

[0001] This utility model relates to the field of lower limb rehabilitation technology, specifically a lower limb rehabilitation device equipped with pressure sensors. Background Technology

[0002] Lower limb rehabilitation devices are medical devices used to help patients restore lower limb function. These devices can be used to treat various lower limb injuries, post-operative recovery, nerve damage, muscle atrophy, and other conditions. Among them, medical spiked shoes are a special type of rehabilitation device. Also known as orthotic shoes or corrective shoes, they are functional shoes specifically designed for foot deformities, fractures, sprains, and other conditions. Their main function is to provide stable and comfortable support for the patient's feet through special design and materials, helping patients regain normal walking function and promoting rehabilitation.

[0003] When using lower limb rehabilitation devices, the patient's foot is supported by the sole of the shoe. Because the pressure during the wearing process cannot be well detected, uneven pressure on different parts of the foot can lead to pressure sores on certain parts of the sole or instep, but the patient is completely unaware of it. This makes it difficult to protect the patient and easily leads to pressure sores and discomfort on the patient's foot. Therefore, in order to solve the above problems, a lower limb rehabilitation device equipped with pressure sensors is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a lower limb rehabilitation device equipped with pressure sensors to solve the problem mentioned in the background art, which is that due to the inability to effectively detect pressure during the wearing process, uneven pressure is applied to different parts of the foot, which can lead to pressure injuries at certain points on the sole or instep, but the patient does not feel anything at all. This fails to provide adequate protection for the patient and easily leads to pressure injuries and discomfort in the patient's feet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lower limb rehabilitation device equipped with a pressure sensor, comprising a shoe body, the shoe body including a sole, an upper fixedly connected to the surface of the sole, a strap provided on the surface of the upper, an installation block provided at the bottom end of the sole, and a crossbar fixedly connected to the surface of the installation block;

[0006] A protective mechanism is provided on the inner side of the sole, the protective mechanism including a pressure sensor, the pressure sensor being fixedly installed on the inner side of the sole, and an alarm being fixedly installed on the surface of the upper.

[0007] Preferably, the protective mechanism further includes a movable groove, which is formed inside the mounting block. A plug rod is movably connected to the inside of the movable groove, and a pull rod is fixedly connected to the surface of the plug rod. A first fixing block is fixedly connected to the lower surface of the sole, and a slot is formed inside the first fixing block. A fixing rod is fixedly connected to the inner wall of the movable groove, and a spring is fixedly connected to the surface of the pull rod.

[0008] Preferably, both the insert rod and the pull rod are movable inside the movable groove, the first fixing block is fixedly connected to the lower surface of the shoe sole in two sets, and the slot is connected to the first fixing block in two sets.

[0009] Preferably, the pull rod is movable on the surface of the fixed rod, and the two ends of the two sets of pull rods and springs are fixedly connected.

[0010] Preferably, an adjustment mechanism is provided on the inner side of the crossbar. The adjustment mechanism includes a rotating rod, which is movably connected to the inner side of the crossbar. A first conical tooth is fixedly connected to the bottom end of the rotating rod. A second fixing block is fixedly connected to the inner wall of the crossbar. A positive and negative screw is movably connected to the inner side of the second fixing block. A second conical tooth is fixedly connected to the surface of the positive and negative screw. A moving block is threadedly connected to the surface of the positive and negative screw. An adjustment rod is fixedly connected to the surface of the moving block. A limit block is fixedly connected to the upper surface of the adjustment rod. A limit groove is formed on the inner side of the crossbar.

[0011] Preferably, the movable blocks are connected in two groups to the positive and negative screws, the adjusting rods are connected in two groups to the movable blocks respectively, and the limiting blocks are movable inside the limiting grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up pressure sensors, pressure on the patient's lower limbs can be detected. When a predetermined value is detected at a certain position on the lower limb, the alarm will automatically sound, thus reminding the patient or nurse to correct the wearing of the lower limb rehabilitation device. This effectively avoids pressure injuries to certain parts of the foot, such as the sole or instep, caused by uneven pressure on different parts of the foot, and provides protection for the patient's feet. At the same time, the cooperation between the plug and the slot allows for the fixing and separation of the mounting block and the sole, making it easy to install and remove the crossbar, and making the use of the crossbar more flexible and convenient.

[0014] By rotating the lever, the first conical tooth can rotate, which in turn drives the second conical tooth to rotate the forward and reverse screws. This allows the moving block to move the adjusting rod under the action of the forward and reverse screws, thereby adjusting the length of the crossbar. This makes the use of the crossbar more flexible, better maintains foot stability, avoids lateral swaying, and prevents foot pronation or supination, which is helpful for the patient's rehabilitation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] The pressure sensor 2 and alarm 21 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A lower limb rehabilitation device equipped with pressure sensors includes a shoe body, which includes a sole 1. An upper 11 is fixedly connected to the surface of the sole 1. A strap 12 is provided on the surface of the upper 11. An installation block 13 is provided at the bottom of the sole 1. A crossbar 14 is fixedly connected to the surface of the installation block 13. The strap 12 allows the patient to wear the sole 1 and the upper 11. The crossbar 14 maintains the curvature and stability of the sole 1, ensuring that the sole 1 is not easily deformed during wear. It also helps to maintain foot stability, prevents lateral swaying, and aids in patient rehabilitation.

[0026] The inner side of the sole 1 is provided with a protective mechanism, which includes a pressure sensor 2. The pressure sensor 2 is fixedly installed on the inner side of the sole 1, and an alarm 21 is fixedly installed on the surface of the upper 11. Through the setting of the pressure sensor 2, the pressure on the patient's foot can be sensed. When the pressure sensor 2 detects that a certain position of the lower limb exceeds the predetermined value, the alarm 21 will automatically sound an alarm, which can remind the patient or nurse to correct the wearing of the lower limb rehabilitation device and avoid foot or instep injury.

[0027] Furthermore, the protective mechanism also includes a movable groove 22, which is located inside the mounting block 13. A rod 23 is movably connected to the inside of the movable groove 22, and a pull rod 24 is fixedly connected to the surface of the rod 23. A first fixing block 25 is fixedly connected to the lower surface of the sole 1, and a slot 26 is provided inside the first fixing block 25. A fixing rod 27 is fixedly connected to the inner wall of the movable groove 22, and a spring 28 is fixedly connected to the surface of the pull rod 24. By setting the pull rod 24, when the pull rod 24 is pulled, the rod 23 will move inside the movable groove 22 under the action of the pull rod 24, thereby realizing the insertion and separation of the rod 23 and the slot 26, which facilitates the installation and removal of the mounting block 13.

[0028] Furthermore, both the insertion rod 23 and the pull rod 24 are movable inside the movable groove 22. The first fixing block 25 is fixedly connected to the lower surface of the sole 1 in two sets. The slot 26 is connected to the first fixing block 25 in two sets. By inserting and separating the insertion rod 23 with the slot 26, the mounting block 13 and the sole 1 can be fixed and separated, thus making the use of the crossbar 14 more flexible.

[0029] Furthermore, the pull rod 24 is movable on the surface of the fixed rod 27. The two sets of pull rods 24 and the two ends of the spring 28 are fixedly connected. Through the setting of the spring 28, the pull rod 24 can be reset, which makes it easier for the pull rod 24 to drive the insertion rod 23 and the slot 26 to be inserted, making it easier to fix the mounting block 13 and the crossbar 14.

[0030] Furthermore, an adjustment mechanism is provided on the inner side of the crossbar 14. The adjustment mechanism includes a rotating rod 3, which is movably connected to the inner side of the crossbar 14. A first conical tooth 31 is fixedly connected to the bottom end of the rotating rod 3. A second fixing block 32 is fixedly connected to the inner wall of the crossbar 14. A positive and negative screw 33 is movably connected to the inner side of the second fixing block 32. A second conical tooth 34 is fixedly connected to the surface of the positive and negative screw 33. A moving block 35 is threadedly connected to the surface of the positive and negative screw 33. An adjustment rod 36 is fixedly connected to the surface of the moving block 35. A limit block 37 is fixedly connected to the upper surface of the adjustment rod 36. A limit groove 38 is opened on the inner side of the crossbar 14. By rotating the rotating rod 3, the first conical tooth 31 is driven to rotate, so that the second conical tooth 34 can rotate under the action of the first conical tooth 31 and drive the positive and negative screw 33 to rotate. In this way, the moving block 35 can drive the adjustment rod 36 to move, thereby adjusting the length of the crossbar 14 and making the wearing of the lower limb rehabilitation device more flexible.

[0031] Furthermore, the movable block 35 is movably connected to the positive and negative screws 33 in two sets, and the adjusting rod 36 is correspondingly connected to the movable block 35 in two sets. The limiting block 37 is movable inside the limiting groove 38. By setting the limiting block 37 and opening the limiting groove 38, the adjusting rod 36 can be prevented from shifting under the action of the positive and negative screws 33, so that the adjusting rod 36 can move stably.

[0032] Working principle: During use, the pressure sensor 2 can sense the pressure on the patient's feet. When the pressure at a certain position on the foot exceeds the predetermined value, the alarm 21 will automatically sound an alarm, thereby reminding the patient or staff to correct the wearing of the lower limb rehabilitation device. By pulling the lever 24, the insertion rod 23 can move inside the movable slot 22 under the action of the lever 24. At the same time, the lever 24 moves on the surface of the fixed rod 27. At this time, the spring 28 is in a contracted state, which can separate the insertion rod 23 from the slot 26. Then the mounting block 13 and the shoe sole 1 can be separated. When it is necessary to install the mounting block 13, the mounting block 13 is placed inside the two sets of first fixed blocks 25. By releasing the lever 24, the lever 24 will be reset under the rebound action of the spring 28, thereby enabling the insertion rod 23 to be inserted into the slot 26 under the action of the lever 24, thus fixing the mounting block 13 and completing the installation of the crossbar 14.

[0033] By rotating the rotating rod 3, the first conical tooth 31 will rotate under the action of the rotating rod 3, and then the second conical tooth 34 will rotate under the action of the first conical tooth 31, driving the positive and negative screws 33 to rotate. The adjusting rod 36 is limited by the limiting block 37 and the limiting groove 38, which will cause the moving block 35 to drive the adjusting rod 36 to move horizontally under the action of the positive and negative screws 33. Then the limiting block 37 moves inside the limiting groove 38, which can extend the length of the crossbar 14.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
