Description

Technical Field

[0001] The invention belongs to the technical field of rehabilitation training equipment, and in particular relates to a fixed pressure training belt and a system after knee replacement surgery. Background Art

[0002] Knee replacement surgery is a procedure used to treat severe knee injury or disease, usually for patients who have severe knee pain and limited function due to arthritis, joint injuries or other diseases.

Postoperative rehabilitation device of knee joint is an important tool to help patients restore joint function and improve the quality of life. However, there are still some shortcomings in the rehabilitation devices on the market. For example, the patent with the publication number of CN114848390B discloses a recumbent lower limb rehabilitation robot based on lasso drive, a passive training mode based on predetermined trajectory traction and an active training mode based on active movement intention, which helps patients restore lower limb muscle strength and mobility, avoids the occurrence of postoperative complications, and is convenient for patients to a certain extent; however, although the device is provided with a pulley, the device itself is relatively bulky and large in size, which greatly affects its portability and use in limited space. At the same time, its structure is complex, and professional technology and time may be required for assembly, adjustment and maintenance.

[0040] The waist belt 1 is used as the support base of the whole system and is made of elastic material. An opening is designed on one side of the waist belt 1, and Velcro is used for quick connection and adjustment, making it easier to wear and adjust. This ensures that it can provide sufficient support while also being able to adapt to users of different body shapes. Hooks are provided on both sides and the back of the waist belt 1. These hooks are connected to the upper end of the knee assembly 2 through the first elastic belt 4. The connection of the first elastic belt allows movement between the waist belt 1 and the knee assembly 2, ensuring that appropriate fixation and pressure can be provided during rehabilitation training, facilitating the training of muscle groups such as the quadriceps femoris.

[0041] Example 2

[0042] The foot component 3 includes a toe component 301 and a heel component 303, which are connected to the knee component 2 via a second elastic band 5. The toe component 301 adopts a frame-shaped soft cover design, and a soft pad that fits the shape of the toes is installed inside to ensure comfort when wearing. The heel component 303 adopts a semicircular frame design, and the heel component 303 works together with the toe component 301, and is connected to the knee component 2 via the second elastic band 5 and the hook. Through the connection of the second elastic band 5, the user's calf has a sufficient range of motion, and at the same time, it can be properly adjusted according to the needs of training, assisting the patient in training the calf muscles from multiple angles. The foot component 3 mainly includes the toe component 301, the heel component 303 and the foot component elastic band 305. The toe component 301 and the heel component 303 are tightened by the elastic band 305 to facilitate fixing the device to the patient's foot;

[0043] Example 3

[0044] In this embodiment, the knee assembly of the present invention is mainly composed of a lower knee component 201 and an upper knee component 202, both of which adopt a cylindrical strap design that can be opened and closed, and the external structure is a hard fixing plate 2012, 2013, which ensures the stability and durability of the assembly during use. The outer side of the cylindrical strap is equipped with Velcro 203, 206, and this design allows the opening of the strap to be quickly and conveniently connected and fixed to adapt to the size and fastening requirements of different users.

[0045] Two elastic band hooks are installed at the lower ends of the lower knee component 201 on both sides, and the hooks are connected to the toe component 301 and the heel component 303 of the foot component 3 through the second elastic band 5, so as to achieve the coordinated movement of the knee joint and the foot. The cylindrical rotating shaft is embedded in the hard structure on both sides of the lower knee component 201, and the design of the upper knee component 202 also takes into account stability and adjustability, and the upper ends and back of the upper knee component 202 on both sides are equipped with elastic band hooks. The inner side of the upper knee component 202 is also provided with elastic band hooks, through which the two upper knee components on the left and right sides of the elastic band 209 can be connected to form another exercise angle. The upper knee component 202 is designed with a rotating shaft hole in the hard structure on both sides, and the rotating shaft hole cooperates with the cylindrical rotating shaft of the lower knee, allowing the upper knee component 202 to keep flexible rotation during exercise.

[0046] A hollow cylinder 2011 is designed on the outside of the rotation axis hole of the upper knee component 202. A sliding groove is provided on the outside of the structure to match the inner protrusion of the knob 204. There are several holes arranged in a circle on the end surface of the structure. The inner diameter of the knob 204 is the same as the outer diameter of the hollow cylinder on the outside of the upper knee rotation axis hole. One end of the spiral spring 2010 is connected to the lower knee component, and the other end is connected to the knob 204, forming an adjustable tension system. Specifically, by rotating the knob 204, the tension of the spiral spring 2010 can be easily adjusted, and the knob 204 and the upper knee component 202 are fixed by the latch 2015, so that the resistance obtained by bending the upper knee component and the lower knee component is different, thereby adapting to the needs of rehabilitation training of different intensities.

[0047] Example 4

[0048] In this embodiment, the knee assembly 2 also includes a weight bag 205. The weight bag 205 can be rotatably mounted on the outside of the upper knee component shaft, and a soft bag that can be opened and closed is provided in the middle, allowing the user to fill it with an appropriate amount of weight according to training needs. This design provides a training method for the user to pressurize the knee after lying down, which helps to improve the effect of rehabilitation training. When not performing knee compression exercises, the weight bag 205 can be removed to increase the flexibility of the device.

It can receive information feedback from the first posture sensor 302, the second posture sensor 304, the third posture sensor 207 and the fourth posture sensor 208 in real time. The posture sensor has an accelerometer, a gyroscope and a position sensor inside.

[0052] The monitoring computer 101 has advanced data processing capabilities and can simulate and analyze the collected motion data, thereby accurately capturing every detail of the user's movements during rehabilitation training. Through spatial modeling and tracking algorithms, it can accurately track and evaluate the movements of the knee joint and foot, such as Figure 7 As shown, the first motion sensors on the left and right sides of the device are equivalently replaced by the user's right toe model 601 and the user's left toe model 701 in the model, the second motion sensors on the left and right sides of the device are equivalently replaced by the user's right heel model 602 and the user's left heel model 702 in the model, the third motion sensors on the left and right sides of the device are equivalently replaced by the user's right calf model 603 and the user's left calf model 703, the fourth motion sensors on the left and right sides of the device are equivalently replaced by the user's right thigh model 604 and the user's left thigh model 704, and the monitoring computer is equivalently replaced by the user's waist 8;
