Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment, and in particular, to a novel walking aid mechanism for orthopedic rehabilitation. Background Technology

[0002] During rehabilitation training, therapists use certain instruments to perform manual therapy on patients, or guide and assist patients in using instruments for training. These instruments are rehabilitation equipment, such as walking aids. They enable elderly patients with mobility impairments or those who have lost the ability to walk to take care of themselves and go out for walks like normal people. The most common walking aids include two-wheeled and four-wheeled walking aids. If you have difficulty maintaining your balance or are prone to falling, both types of walking aids can provide you with sufficient stability. However, currently used walking aids require you to hold your hand in one place and rely on the walking aid for your entire body, which puts a lot of stress on your wrist, causing hand fatigue and a poor user experience. Summary of the Invention

[0003] To address the above problems, this invention provides a novel walking assistance mechanism for orthopedic rehabilitation.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a novel walking assistance mechanism for orthopedic rehabilitation, the structure of which includes a protective baffle, a connecting rod, a lifting bracket, side baffles, and movable wheels. The upper ends of the lifting brackets are welded together with the connecting rod, and movable wheels are installed at the bottom of each lifting bracket. The side baffles are respectively installed on the left and right sides of the lifting brackets, and the protective baffle is fixed between the two lifting brackets and located at the lower end of the connecting rod.

[0005] As a further improvement of the present invention, the lifting bracket includes a protective sleeve assembly, an electric lifting rod, a rod sleeve, a motor, a connecting wire, a controller, and a control button. The controller is equipped with a control button and is mounted on a side baffle. The controller and the motor are electrically connected by a connecting wire. The motor is located at the bottom inner part of the rod sleeve and is mechanically connected to the electric lifting rod. The electric lifting rod has a 7-shaped structure, and the protective sleeve assembly is fixed between the electric lifting rods.

[0006] As a further improvement of the present invention, the sheath assembly includes a receiving cavity, a spring, a horizontal push block, a swing rod, a protective pad, an electric push rod, a fixing groove, and an airflow guiding structure. The receiving cavity is provided with an airflow guiding structure and an electric push rod. The electric push rod is horizontally arranged. There are four swing rods, and the swing rods are symmetrically distributed on the left and right ends of the outer side of the receiving cavity. The horizontal push block and the spring are on the same parallel line. The protective pad is connected by the swing rod. The fixing groove and the receiving cavity are an integrated structure. The fixing groove is fixed to the electric lifting rod.

[0007] As a further improvement of the invention, the upper ends of the swing arms are connected by a crossbar that passes through the receiving cavity and is parallel to each other. One crossbar is connected to the electric push rod, and the other crossbar is placed between the spring and the horizontal push block.

[0008] As a further improvement of the present invention, the receiving cavity is provided with a partition and an exhaust port. The partition has two or more exhaust ports arranged in a straight line. The exhaust ports are fitted to the bottom of the protective pad. The exhaust ports are connected to the airflow guiding structure in a communicating manner.

[0009] As a further improvement of the present invention, the airflow guiding structure includes an air guide pipe, a mounting base, a signal contact rod, a horizontal swing rod, an air pump, a turntable, and a support base. The air guide pipe is connected to the air pump. Two air pumps are provided and mounted on the mounting base. The signal connector of the air pump is located on the support base. The two ends of the signal contact rod are respectively provided with moving contacts, which are in contact with the signal connector of the air pump. The signal contact rod and the turntable are at the same center. The signal contact rod is oscillatingly connected to the turntable. The two ends of the turntable are provided with horizontal swing rods in a Z-shape. The end of the horizontal swing rod relative to the turntable is connected to the swing rod.

[0010] The beneficial effects of this invention are:

[0011] The lifting bracket of this invention is equipped with an electric lifting rod, which can be electrically raised and lowered by a motor. When the user's hands become tired from holding the device, the electric lifting rod can be raised to a support position under the armpits, thereby relieving pressure on the hands, making it easier to use and improving comfort.

[0012] The present invention includes a sheath assembly between the electric lifting rods, in which a pad is disposed on the outside of the receiving cavity. When using underarm support, the soft contact of the pad can improve the patient's comfort underarm support.

[0013] The present invention provides a pad that works in conjunction with a swing arm. When the swing arm swings from an inclined position to an upright position along the receiving cavity, the upright position lifts up the pad, thereby exposing the exhaust port. When using the walking assistance mechanism in hot weather, the gas discharged from the exhaust port can increase heat dissipation under the armpit, keeping the armpit area cool.

Each lifting bracket 3 includes a protective sleeve assembly 31, an electric lifting rod 32, a rod sleeve 33, a motor 34, a connecting wire 35, a controller 36, and a control button 37. The controller 36 has a control button 37 and is mounted on the side baffles 4. The motor 34 is electrically connected to the electric lifting rod 32 via a connecting cable 35. The motor 34 is located at the bottom inner part of the rod sleeve 33. The motor 34 is mechanically connected to the electric lifting rod 32, which has a 7-shaped structure. A protective sleeve assembly 31 is fixed between the electric lifting rods 32. The protective sleeve assembly 31 includes a receiving cavity 311, a spring 312, a horizontal push block 313, a swing rod 314, a protective pad 315, an electric push rod 316, a fixing groove 317, and an airflow guiding structure 318. The receiving cavity 311 is provided with an airflow guiding structure 318 and an electric push rod 316. The electric push rod 316 is horizontally arranged. There are four swing rods 314, which are symmetrically distributed on the outer left side of the receiving cavity 311. At both ends, the horizontal push block 313 and the spring 312 are on a parallel line. The protective pad 315 is connected by a swing rod 314. The fixing groove 317 and the receiving cavity 311 are an integrated structure. The fixing groove 317 is fixed to the electric lifting rod 32. The upper ends of the swing rods 314 are connected by a crossbar. The crossbar passes through the receiving cavity 311 and is parallel to each other. One crossbar is connected to the electric push rod 316, and the other crossbar is placed between the spring 312 and the horizontal push block 313. The receiving cavity 311 is provided with a partition groove 11a and an exhaust port 11b. The partition groove 11a has two or more exhaust ports 11b arranged in a straight line. The exhaust ports 11b fit at the bottom of the protective pad 315 and are connected to the airflow. The airflow guiding structure 318 is connected in a continuous manner. It includes an air guide pipe 18a, a mounting base 18b, a signal contact rod 18c, a horizontal swing rod 18d, an air pump 18e, a turntable 18f, and a support base 18g. The air guide pipe 18a communicates with the air pump 18e. Two air pumps 18e are provided and mounted on the mounting base 18b. The signal connector of the air pump 18e is located on the support base 18g. The two ends of the signal contact rod 18c are respectively provided with moving contacts, which engage with the signal connectors of the air pump 18e. The signal contact rod 18c and the turntable 18f are concentric. The signal contact rod 18c is oscillatingly connected to the turntable 18f. The two ends of the turntable 18f are provided with horizontal swing rods 18d in a Z-shape.The horizontal swing arm 18d is connected to the swing arm 314 at one end relative to the turntable 18f.

[0023] The working principle of the walking assistance mechanism in the above technical solution is explained below:

[0024] In use, the patient can first adjust the walking aid mechanism to their preferred mode of operation. The device can be switched from a hand-held position to an underarm support position, with the hand-held position being the standard usage. To switch from hand-held to underarm support, the control button 37 on the side panel 4 is pressed to start the motor 34. The motor 334 raises the electric lifting rod 32 to a suitable height, and then the button is pressed again to stop. The electric push rod 316 is then activated, pushing the swing arm 314 in a straight line. The swing arm moves from an inclined position to an upright position. When upright, the swing arm 314 separates the groove 11a of the padding 315, exposing the exhaust port 11b. At this time, as the swing arm 314 swings, it drives the horizontal swing arm 18d to swing, causing the turntable 18f to rotate counterclockwise. During the rotation of the turntable 18f, the signal contact rod 18c, which is at the same center, rotates synchronously. The moving contact on the signal contact rod 18c connects with the signal contact of the air pump, thereby starting the air pump 18e. After the air pump 18e is started, the gas is continuously output through the air guide tube 18a and then discharged through the exhaust port 11b. This achieves the synchronous exhaust work of the exhaust port 11b when the pad 315 is opened. The output gas acts on the patient's armpit area, which can reduce the patient's armpit temperature and reduce armpit sweating in hot weather, thus improving the comfort of use.
