Description

Technical Field

[0001] The present invention relates to the technical field of critical care rehabilitation, and particularly to a walking assistance device for critical care rehabilitation. Background Art

[0002] In the field of critical care rehabilitation, the restoration of walking ability is a key step for patients to regain the ability of self-care. Traditional rehabilitation walking assistance devices mainly focus on providing support and stability to help patients relearn walking, but often pay insufficient attention to the exercise of respiratory function. As the basis of life activities, respiratory function is also crucial for the rehabilitation of critically ill patients. However, existing rehabilitation equipment often conducts walking exercise and respiratory exercise separately, which not only increases the complexity of the rehabilitation process but also may affect the overall rehabilitation effect.

[0003] In addition, traditional rehabilitation walking assistance devices have some limitations in design and use. For example, the height of many devices is not adjustable and cannot meet the needs of patients with different heights and body types, resulting in inconvenient use. At the same time, some devices lack sufficient stability and comfort, which may cause additional physical burden to patients. In view of the above problems, the present invention proposes a walking assistance device for critical care rehabilitation, aiming to combine walking assistance with respiratory exercise function and provide a comprehensive and efficient rehabilitation solution.

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the following described embodiments are only partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] To more clearly explain and illustrate the technical solutions and implementation methods of the present invention, the following introduces the preferred specific embodiments for implementing the technical solutions of the present invention.

[0023] Refer to the appendix of the specification Figure 1 -Appendix Figure 5As shown in the figure: This severe illness rehabilitation walking assistance device includes a walking assistance frame 1 and a breathing exercise mechanism 2 fixed to its right side. The walking assistance frame 1 adopts a bilateral symmetric design to provide stable support. The breathing exercise mechanism 2 realizes the breathing training function through airbag compression and air flow circulation, and the two work together to improve the rehabilitation efficiency.

[0024] The specific composition of the walking assistance frame 1 includes: Two mirror-symmetric inverted T-shaped aluminum alloy tubes form the main body framework. A rotating shaft 15 is provided at the front section of the bottom, and the rear section penetrates through the transmission shaft 110. An inner convex block 18 is welded for connecting the support structure. The aluminum alloy telescopic rod 11 is inserted into the port at the top of the T-shaped hollow tube 14. The equidistant threaded holes on the outer wall are aligned with the corresponding holes of the T-shaped hollow tube 14, and the height is fixed by bolts to realize the adjustment of the grip height. Among them, a lithium battery is placed in the inner cavity of the T-shaped hollow tube 14, and a speed control button is provided on the left grip. The speed of the reduction motor 111 is adjusted through the control main board to realize the hierarchical control of the auxiliary walking speed. The plastic grip 12 is fixed to the top of the telescopic rod, and anti-slip lines are provided on the surface; a nylon ring is provided at the rear to prevent the hand from slipping, and the right grip integrates control buttons.

[0025] The front guide wheel 17 is hinged to the rotating shaft 15 through an inverted U-shaped bracket 16 and can freely rotate 360° to adapt to different walking directions. The rear roller 19 is driven by a reduction motor 111. The motor output shaft is connected to the transmission shaft 110 through a coupling. Both ends of the transmission shaft are fixed in the circular holes of the T-shaped hollow tube 14 through bearings for stable transmission. The top ends of two cross-shaped X-shaped inclined rods 112 are fixed with a cross beam 113, and a canvas surface 114 is connected between the cross beams to form a hip support surface. The intersection of the inclined rods is hinged through a shaft pin, and the bottom is hinged to the convex block 18 through a round tube 115. A hoop 117 is provided on the outer circle of the T-shaped hollow tube 14. The C-shaped hook 116 on the inner side can hook the cross beam 113. When folding, the inclined rod 112 is folded upward and hooked and fixed to reduce the occupied space.

[0026] The specific composition of the breathing exercise mechanism 2 includes: The top frame 21 and the bottom frame 22 are welded together and fixed to the outer wall of the right T-shaped hollow tube 14. A servo electric cylinder 211 is installed on the top frame 21. An arc-shaped plastic block 23 is provided at the bottom of the inner cavity of the bottom frame 22, and its upper surface has a groove for accommodating the airbag 26. The telescopic shaft of the servo electric cylinder 211 is connected downward to the movable frame 210, and an extrusion plate 29 is fixed to the bottom of the movable frame. The stroke of the electric cylinder is adjusted through the control knob to control the extrusion frequency.

[0027] The airbag 26 is made of elastic silica gel, and a partition is provided inside to divide it into left and right chambers. The left chamber is connected to the intake pipe 28 with an air filter and the air delivery pipe 24, and the right chamber is connected to the exhaust pipe 27 and the return pipe 25. The valve bodies in the air delivery pipe 24 and the intake pipe 28 only allow the air flow to move from front to back, that is, external air → left chamber of the airbag → air delivery pipe 24 → patient's mouth and nose; the valve bodies in the exhaust pipe 27 and the return pipe 25 only allow the air flow to move from back to front, that is, the exhaled gas of the patient → return pipe → right chamber of the airbag → exhaust pipe for discharge.

[0028] The description of the working process is as follows: Hook the cross beam 113 on the C-shaped hook 116, unfold the diagonal rod 112 to the supporting state, adjust the draw rod 11 to an appropriate height and lock the bolt. Charge the lithium battery through the charging interface and turn on the main switch on the grip. The patient holds the plastic grip 12, with the back fitting the canvas belt 13, selects the auxiliary speed through the speed control button and walks slowly. The canvas belt 13 fits the user's back, and together with the hip canvas surface 114 forms a three-point support to adapt to patients with different body types. The reduction motor 111 drives the rear roller 19 to provide walking assistance, and the speed control button realizes three-speed switching of "low speed - medium speed - high speed"; the front guide wheel 17 has flexible steering to avoid the risk of sudden stop. During walking, the patient can set the breathing extrusion frequency, such as 10 - 30 times per minute, through the right grip knob to achieve coordinated training of gait and breathing rhythm.

[0029] The servo electric cylinder 211 drives the pressing plate 29 to press down the left chamber of the airbag, and the external air enters and is compressed through the intake pipe 28, and the air flow is delivered to the patient's mouth and nose through the air delivery pipe 24. After the servo electric cylinder 211 resets, the left chamber of the airbag expands to inhale new air; the exhaled gas of the patient enters the right chamber of the airbag through the return pipe 25 and is then discharged through the exhaust pipe 27. After use, fold the diagonal rod 112 and hook it on the C-shaped hook 116, retract the draw rod 11, and turn off the power.
