Technical Field

[0001] This utility model relates to rehabilitation medical assistive devices, specifically to a wearable lumbar rehabilitation assistive device. Background Technology

[0002] In modern society, lumbar spine diseases (such as lumbar disc herniation and lumbar muscle strain) have become prevalent chronic illnesses, especially affecting middle-aged and elderly people and those who work at desks for long periods. Abnormal lumbar curvature is a common cause of chronic low back pain. Clinical studies have shown that dynamically maintaining the normal curvature of the lumbar spine can effectively relieve intervertebral disc pressure and promote muscle function recovery. Existing static fixation orthoses not only completely restrict lumbar spine movement during normal walking, causing difficulty in movement and inconvenience, but may also adversely affect the treatment of lumbar spine diseases and the recovery of lumbar function. Utility Model Content

[0003] The present invention aims to provide a wearable lumbar rehabilitation assistive device that is convenient to use and suitable for dynamically maintaining the normal curvature of the lumbar spine. This lumbar rehabilitation assistive device allows the wearer's waist to move within an appropriate range, which is conducive to patients' walking, sitting and lying down movements. At the same time, it can also keep the wearer's lumbar spine in a normal curve in different postures, thereby promoting the treatment of lumbar spine diseases and the recovery of lumbar function.

[0004] To achieve the above objectives, this utility model provides a wearable lumbar rehabilitation assistive device, comprising:

[0005] The upper and lower waistbands are set vertically spaced apart from each other;

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to the upper, lower, left, and right as shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself.

[0027] Reference Figure 1 and Figure 2As shown, this utility model provides a wearable lumbar rehabilitation assistive device, which can be used as a lumbar exoskeleton to assist patients with lumbar spine diseases (especially lumbar curvature disorders) in rehabilitation or corrective treatment. Specifically, the lumbar rehabilitation assistive device includes an upper waist belt 1 and a lower waist belt 2 arranged vertically spaced apart from each other. The lower waist belt 2 is adapted to be worn around the patient's hips, and the upper waist belt 1 is located above it and adapted to be worn near the top of the patient's waist. The upper waist belt 1 and lower waist belt 2 are respectively formed into loops suitable for wrapping around the waist and have an appropriate width in the vertical direction to reduce patient discomfort caused by long-term wear. Because the upper waist belt 1 and lower waist belt 2 are worn relatively independently on the patient, the lumbar rehabilitation assistive device allows the wearer's waist to move within an appropriate range when performing actions such as walking, sitting, and lying down, making it convenient to use.

[0028] At positions corresponding to the lower back of the wearer, such as the upper waist belt 1 and the lower waist belt 2, a waist support mechanism 3 is also connected. This waist support mechanism 3 includes multiple first push rods 31 arranged vertically to abut against the lower back of the wearer from behind. Figure 3 As shown, this lumbar rehabilitation assistive device can apply compressive and limiting forces to multiple lumbar vertebrae of the wearer using multiple first push rods 31, thereby maintaining the normal curvature of the lumbar spine in different postures and promoting the treatment of lumbar diseases and the recovery of lumbar function. Furthermore, in conjunction with the lumbar motion sensor data of the wearer subsequently detected, these first push rods 31 can be controlled to extend or retract appropriately, allowing for small-amplitude dynamic adjustments based on the patient's body shape and movement posture, effectively relieving intervertebral disc pressure and promoting muscle function recovery.

[0029] Each of the first push rods 31 has a flexible head 34 at its free end, which can abut against the lower back of the wearer, thereby gently applying pressure to the lumbar spine to control the lumbar curve without damaging the lumbar spine or the skin of the lower back. Furthermore, the lumbar support mechanism 3 can be equipped with five first push rods 31 corresponding to the five different lumbar vertebrae, thereby applying force to the L1-L5 lumbar vertebrae respectively.

[0030] To accommodate patients of different body types, the upper waist belt 1 and lower waist belt 2 of this lumbar rehabilitation assistive device can be adjusted to have different wrapping lengths. Therefore, the wrapping lengths of the upper waist belt 1 and lower waist belt 2 can be selectively adjusted according to the wearer's body size or the desired tightness. This adjustment can be achieved through various structural forms, such as pin buckle, plate buckle, ring buckle, or hook buckle.

[0031] Typically, the upper waistband 1 and lower waistband 2 are made of a flexible material to fit snugly around the wearer's waist. To facilitate connection of the waist support mechanism 3 and related components such as the second push rod 6 and mounting bracket 7, multiple rigid clips 4 spaced apart circumferentially can be provided on them. For example, metal clips can be provided on the upper waistband 1 and lower waistband 2 at positions corresponding to the left front, right front, left rear, and right rear of the body.

[0032] The rigid plate 4 on the upper waist belt 1 can be equipped with sensors 5 to sense the wearer's waist movements, detecting sensory data (such as pressure) and making corresponding adjustments based on this data, such as controlling the movement of the first push rod 31. A second push rod 6 is mounted on the rigid plate 4 on the lower waist belt 2. The top of the second push rod 6 is connected to the corresponding rigid plate 4 on the upper waist belt 1 or the aforementioned sensor 5, enabling it to drive and adjust the relative positions of the upper waist belt 1 and the lower waist belt 2. Through this arrangement, the wearer's position and posture after waist movement are determined based on the sensor data detected by the sensors 5, thereby adjusting each second push rod 6 to have an appropriate extension length to maintain the normal curve of the wearer's lumbar spine. This is combined with... Figure 4 As shown, the second push rod 6 can be installed onto the rigid plate 4 on the lower waist belt 2 via the first ball joint 12, and connected to the corresponding rigid plate 4 on the upper waist belt 1 via a horizontal pivot at the top, so as to facilitate the relative movement of the upper waist belt 1 and the lower waist belt 2.

[0033] Corresponding to the normal waist size of the human body, the distance between the upper waist belt 1 and the lower waist belt 2 can be set to 22-26cm, such as about 24cm, so that when the lower waist belt 2 is worn on the patient's hips, the upper waist belt 1 is roughly located at the top of the patient's waist.

[0034] Combination Figures 4 to 6 As shown, in a preferred embodiment of the wearable lumbar rehabilitation assistive device according to this utility model, a mounting bracket 7 is also provided on the rear side of the lower waist belt 2. The mounting bracket 7 can be connected to a rigid plate provided on the lower waist belt 2 via a connecting slot 15. Thus, the mounting bracket 7 provides a mounting base for the lumbar support mechanism 3, which can be connected to the outside of the lower waist belt 2 via the mounting bracket 7.

[0035] In the preferred embodiment illustrated, the mounting bracket 7 is formed as a semi-elliptical component extending along the periphery of the lower waistband 2 and has appropriate rigidity. At both ends of the lower waistband 2, the mounting bracket 7 is connected to a leg support 8 via a second ball joint 13. The bottom end of the leg support 8 is provided with a strap 9 for securing the wearer's legs. With this arrangement, a portion of the force exerted on the lower waistband 2 during waist movement can be transmitted to the wearer's legs through the leg support 8. For example, by securing the strap 9 to the area above the knee joint of the wearer's legs, this area can bear part of the force transmitted from the waist, reducing the burden on the lower back.

[0036] In addition, a control box 10 can be installed on the mounting bracket 7. The control box 10 can contain a controller, circuit board and power supply, etc., for controlling the extension of the first push rod 31, the second push rod 6 and the third push rod 33, etc.

[0037] Reference Figure 3 As shown, the lumbar support mechanism 3 can be configured to include an assembly frame 32, which can be connected to the side of the mounting bracket 7 opposite to the lower lumbar belt 2 via a third ball joint 14. In the illustrated preferred embodiment, the assembly frame 32 has a vertically arranged mounting plate and a horizontally arranged connecting plate. The ball head of the third ball joint 14 can be located at one end of the connecting plate to form a ball joint engagement with a ball socket located on the mounting bracket 7 or the control box 10. A plurality of first push rods 31 can be mounted on the mounting plate and extend toward the area between the upper lumbar belt 1 and the lower lumbar belt 2 to abut against the patient's lower back and act on the respective lumbar vertebral segments.

[0038] Furthermore, the mounting bracket 7 may also be equipped with a guide frame 11, which has multiple limiting holes arranged in a vertical direction. Each first push rod 31 extends through the corresponding limiting hole so that the deflection angle of these first push rods 31 can be limited by the guide frame 11, thereby effectively acting on different lumbar vertebral segments.

[0039] At a height corresponding to the upper waist belt 1, a pair of third push rods 33 can be installed on the assembly frame 32. These third push rods 33 are ball-jointed to the assembly frame 32 and pivotally connected to the upper waist belt 1 via vertical axes at their telescopic ends. Thus, by adjusting the extension of the third push rods 33, the relative orientation of the assembly frame 32 with the upper waist belt 1 and lower waist belt 2 can be adjusted, thereby finely adjusting the angle of the assembly frame 32 around the vertical axis. This allows the wearer to perform waist-twisting movements within a small angle range without affecting the normal curve of their lumbar spine, thus maintaining a healthy lumbar curve even with slight waist movements during exercise and walking.

[0040] In the preferred embodiment described above, the various parts of the lumbar rehabilitation assistive device are preferably made of lightweight materials to reduce the weight burden on the wearer. Specifically, the first, second, and third push rods are preferably electric push rods.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
