Description

Technical Field

[0001] This utility model belongs to the field of training device technology, specifically relating to a home-use portable passive training device for leg muscles of patients with lower limb paralysis. Background Technology

[0002] Long-term bedridden patients, especially those with lower limb paralysis, are prone to muscle atrophy, joint stiffness, and poor blood circulation due to a lack of voluntary movement, which seriously affects their quality of life. Since patients have no control over their lower limbs and cannot exercise on their own, family members and caregivers need to manually exercise them, which places a great burden on caregivers.

[0003] Therefore, a home-use portable passive leg muscle trainer for patients with lower limb paralysis has significant social and practical value. However, most existing passive lower limb muscle rehabilitation trainers focus on flexion and extension exercises of the patient's lower limbs, but rarely address abduction and adduction movements of the lower limbs. This makes active rehabilitation training difficult and inconvenient for people to use. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed portable passive training device for leg muscles of patients with lower limb paralysis for home use, in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A home-use portable passive leg muscle trainer for patients with lower limb paralysis includes a mounting shell. The mounting shell has a thigh fixation mechanism and a lower leg fixation mechanism at its two ends. An actuator for driving the lower leg fixation mechanism is installed inside the mounting shell. The actuator includes a threaded rod rotatably connected inside the mounting shell, a threaded sleeve threadedly connected to the outside of the threaded rod, and two movable plates mounted on one side of the threaded sleeve. One end of each movable plate extends to the outside of the mounting shell and is fitted with a mounting base. A rotation mechanism for driving the threaded rod to rotate is installed inside the mounting shell.

[0007] As a further optimization of this utility model, the thigh fixing mechanism includes a first card plate and two first straps installed on one side of the first card plate. The other side of the first card plate has two first strap holes for use with the first straps. One end of the mounting shell is rotatably connected to one side of the first card plate.

[0008] As a further optimization of this utility model, the lower leg fixing mechanism includes a second clamping plate and two second straps installed on one side of the second clamping plate. The other side of the second clamping plate has two second strap holes for cooperating with the second straps. An ear piece is installed on one side of the second clamping plate, and the ear piece is rotatably connected to the mounting base.

[0009] As a further optimization of this utility model, both the first card plate and the second card plate have an arc-shaped structure, and both the first card plate and the second card plate have a soft pad installed on the side closest to the human body.

[0010] As a further optimization of this utility model, the rotating mechanism includes a drive wheel rotatably connected inside the mounting housing, a driven wheel rotatably connected inside the mounting housing and meshing with the drive wheel, and a brushless motor installed outside the mounting housing for driving the drive wheel to rotate. The driven wheel is fixedly connected to the outside of the threaded rod. A control module electrically connected to the brushless motor is installed inside the mounting housing. A wire located outside the mounting housing is electrically connected to the control module. A controller is installed at one end of the wire, and the controller is equipped with multiple control buttons.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] like Figure 1 - Figure 4As shown, a home-use portable passive leg muscle trainer for patients with lower limb paralysis includes a mounting shell 1. The mounting shell 1 has a thigh fixation mechanism 2 and a lower leg fixation mechanism 3 at its two ends. The thigh fixation mechanism 2 includes a first locking plate 21 and two first straps 22 mounted on one side of the first locking plate 21. The other side of the first locking plate 21 has two first strap holes 23 for use with the first straps 22. One end of the mounting shell 1 is rotatably connected to one side of the first locking plate 21. The lower leg fixation mechanism 3 includes a second locking plate 31, and... Two second straps 32 are installed on one side of the second card plate 31. Two second strap holes 33 are opened on the other side of the second card plate 31 to cooperate with the second straps 32. An ear piece 5 is installed on one side of the second card plate 31. The ear piece 5 is rotatably connected to the mounting base 14. Both the first card plate 21 and the second card plate 31 have an arc-shaped structure. A soft pad 6 is installed on the side of the first card plate 21 and the second card plate 31 that is close to the human body. The soft pad 6 is placed between the human body and the first card plate 21 and the second card plate 31 to reduce pressure and make the human body more comfortable.

[0025] When the first clamp 21 is attached to the bottom of the thigh, the two first straps 22 are wrapped around the upper side of the thigh and inserted into the first strap hole 23 from one side, and then out from the other side of the first strap hole 23. The tightness of the first straps 22 can be adjusted according to the thickness of the thigh. Then the first straps 22 are tied tightly at the first strap hole 23. When the second clamp 31 is attached to the bottom of the calf, the two second straps 32 are wrapped around the upper side of the calf and inserted into the second strap hole 33 from one side, and then out from the other side of the second strap hole 33. The tightness of the second straps 32 can be adjusted according to the thickness of the calf. Then the second straps 32 are tied tightly at the second strap hole 33. This can be adapted to patients of different body types.

[0026] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, an actuator for driving the lower leg fixing mechanism 3 to move is installed inside the mounting housing 1. The actuator includes a threaded rod 11 rotatably connected inside the mounting housing 1, a threaded sleeve 12 threadedly connected to the outside of the threaded rod 11, and two movable plates 13 installed on one side of the threaded sleeve 12. One end of each movable plate 13 extends to the outside of the mounting housing 1 and is equipped with a mounting base 14. A rotating mechanism for driving the threaded rod 11 to rotate is installed inside the mounting housing 1. The rotating mechanism includes a driving wheel 15 rotatably connected inside the mounting housing 1, a driven wheel 16 rotatably connected inside the mounting housing 1 and meshing with the driving wheel 15, and a brushless motor 17 installed outside the mounting housing 1 for driving the driving wheel 15 to rotate. The driven wheel 16 is fixedly connected to the threaded rod 11. Outside the rod 11, inside the mounting housing 1, there is a control module 18 electrically connected to the brushless motor 17. The control module 18 is electrically connected to a wire 19 located outside the mounting housing 1. One end of the wire 19 is equipped with a controller 20, which has multiple control buttons, namely a constant speed control button, a constant thrust adjustment button, a speed adjustment button, a stop button, and a power on / off button. Inside the mounting housing 1, there are two limiting mechanisms. The limiting mechanism includes a fixed plate 4 installed on the inner wall of the mounting housing 1, a limiting rod 41 installed between the fixed plate 4 and the inner wall of the mounting housing 1, and a limiting sleeve 42 sleeved outside the limiting rod 41. One side of the limiting sleeve 42 is fixedly connected to one side of the threaded sleeve 12.

[0027] In use, the first clamping plate 21 can be placed at the bottom of the thigh and secured to the thigh with two first straps 22. The second clamping plate 32 can be placed at the bottom of the calf and secured to the bottom of the calf with two second straps 33. The actuator can be turned on by pressing the power button. At this time, press the constant speed control button, constant thrust adjustment button, or speed adjustment button according to the desired movement state. After pressing, the brushless motor 17 will drive the drive wheel 15 to rotate. Under the meshing of the drive wheel 15 and the driven wheel 16, the threaded rod 11 will drive the threaded sleeve 12 to move. Under the drive of the threaded sleeve 12, the two moving plates 13 will drive the mounting base 14 to move. Under the drive of the mounting base 14, the second clamping plate 32 will move, thereby driving the calf to move, so that its angle and position are changing, achieving abduction and adduction movements of the lower limbs, so that the lower limb muscle groups can be fully exercised.

[0028] The actuator has three setting modes: passive force measurement mode, active constant force mode, and active constant speed mode, which are designed for patients with different weights and conditions.

[0029] Passive force measurement mode: During use, press the constant speed control key, and the whole system will measure the force on the actuator in real time at different angles of the actuator at the set movement speed. This is used to judge the patient's muscle health status and is generally applied to patients with mild muscle atrophy.

[0030] Active constant force model: The actuator is set to reciprocate with a constant thrust by adjusting the thrust constant key. At this time, the magnitude of the actuator thrust is constant, and the speed of movement changes with the stroke. If the patient's weight is small and cannot reach the set force value, weights can be added to the patient's legs to increase the force value and achieve the purpose of strengthening the exercise. It is generally used for patients with moderate to severe muscle atrophy.

[0031] Active constant speed mode: The actuator is set to move at a constant speed by adjusting the constant thrust. At this time, the force value changes with the stroke. Different speed levels can be set by adjusting the speed. This mode is generally used for patients with muscle atrophy in the rehabilitation stage.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
