Description

Technical Field

[0001] The present invention relates to the technical field related to rehabilitation equipment, and in particular to a lower limb function rehabilitation exercise treatment chair. Background Art

[0002] In recent years, the number of people with limb motor dysfunction caused by work-related injuries, traffic accidents, aging and other reasons has been increasing day by day, which has brought serious inconvenience and mental distress to the patients themselves, and also caused a certain burden on their families and society. For people with disabilities, sitting is the main way of daily life due to the limitations of limb defects. However, maintaining a sitting posture for a long time will have a great impact on physical health. Long-term sitting can cause muscle relaxation, lower body swelling and other problems. At the same time, due to the increased pressure on the thigh area, blood return is affected, and the abnormal curvature of the spine can cause damage to internal organs and muscle atrophy. From the perspective of human biomechanics, frequently changing body posture and exercising the legs can reduce fatigue, reduce load and promote blood circulation.

[0003] Referring to the Chinese invention patent, publication number: CN 110074925 A, title: Lower Limb Rehabilitation Wheelchair, the invention can provide separate independent rehabilitation exercise training for the left leg and the right leg respectively through the first rehabilitation training device and the second rehabilitation training device, and can also work simultaneously to provide combined rehabilitation exercise training for both legs, so that the rehabilitation training plan can be set according to the user's own situation. The first telescopic device and the second telescopic device are connected to the wheelchair body. When not in use, they can be retracted to a position such as close to the wheelchair and used as a footrest of the wheelchair, which is also convenient for users to get on and off the wheelchair. When in use, the first rehabilitation training device and / or the second rehabilitation training device can be extended to facilitate the passengers to perform normal rehabilitation exercises; in addition, since the first rehabilitation training device and the second rehabilitation training device are respectively connected to the telescopic device, the position of the first rehabilitation training device and / or the second rehabilitation training device can be adjusted through the telescopic device according to the leg length of the user during use to adapt to users with different leg lengths.

[0004] However, in actual use, the above technical solutions and similar technical solutions still have some problems:

[0005] 1. The design of this type of wheelchair limits the patient's position changes during rehabilitation training, which is limited to sitting position. This limitation hinders the comprehensive and dynamic rehabilitation training of the patient's lower limbs, and thus fails to fully simulate the muscle activation and coordination training in the walking state. Compared with walking training, its rehabilitation effect is insufficient;

[0006] 2. The wheelchair lacks the functional design to facilitate the patient's transition from sitting to standing, which limits the patient's ability to try to stand and walk. This not only affects the patient's recovery process of lower limb strength, but also may hinder the reconstruction of their self-confidence due to the lack of successful experience, which has an adverse effect on psychological rehabilitation;

[0007] 3. In terms of safety performance, the wheelchair lacks an effective buffering protection mechanism when encountering unexpected situations such as rollover, which increases the risk of injury to patients. In addition, long-term use of the wheelchair in a sitting position may increase the risk of orthostatic hypotension in patients. When the patient tries to stand up or faints, the wheelchair is not equipped with an emergency oxygen supply or position adjustment system to alleviate the symptoms, which further aggravates the health risks that the patient may face and is not conducive to the rapid stabilization of the condition and subsequent recovery.

[0049] Embodiment 3:

[0050] Based on Example 2, Figure 4A lower limb functional rehabilitation exercise treatment chair, a seat 24 is connected to a training mechanism 4, the training mechanism 4 includes a pressing plate 45, the two ends of the seat 24 are slidably connected with the pressing plates 45, a pair of sliding rods 43 are installed at the bottom end of the seat 24, the pressing plate 45 is slidably connected to the sliding rods 43, and a second spring 44 is installed between the pressing plate 45 and the seat 24; the seat 24 is rotatably connected to the electric wheelchair 1, a gear 46 is installed on the rotating shaft of the seat 24, and a rack 47 is installed on the lifting rod 26, and the rack 47 is used to mesh with the gear 46.

[0051] Working principle: the patient can sit on the electric wheelchair 1 and move through the electric wheelchair 1. When the patient needs to carry out rehabilitation training for the lower limbs, the waist is bound by the restraint belt 23. The restraint belt 23 is bound by Velcro. The electric push rod 28 is started, and the electric push rod 28 is extended, thereby pushing the lifting rod 26 to rise, and the backrest 22 is pulled up by the first spring 27. The backrest 22 pulls a pair of slides 21 to rise through the fixed rod 25. Under the action of the pull rope 7, the patient is pulled to stand up by pulling the restraint belt 23. The patient slowly stands up and can practice walking slowly by holding the slides 21 with both hands. The electric push rod 28 continues to extend, thereby continuing to lift through the first spring 27. The first spring 27 can play a buffering role to avoid directly lifting the patient through the restraint belt 23. The first spring 27 can lift the patient through elastic deformation, thereby reducing the gravity on the patient, making the patient lighter, reducing the force on the legs, avoiding excessive training, and thus facilitating the patient's slow walking training;

[0052] During walking training, the electric wheelchair 1 is prone to tipping over due to the high center of gravity of the electric wheelchair 1 after standing. When the patient loses strength due to overtraining or faints due to positional vertigo, the patient drives the electric wheelchair 1 to tip over, and the electric wheelchair 1 tilts to one side. The gyroscope 34 detects that the electric wheelchair 1 has tipped over. When the angle between the electric wheelchair 1 and the ground is less than forty-five degrees, the electric wheelchair 1 starts the solenoid valve 38, and the compressed oxygen inside the oxygen tank 33 will quickly enter the inside of the trachea 31, so that the airbag 35 is quickly filled with air and expanded. The airbag 35 can play a buffering role when the electric wheelchair 1 tips over, thereby preventing the patient from being injured. When the airbag 35 expands, it pushes the top cover 322 to extend, and the top cover 322 slides along the guide groove 323 through the guide wheel 324, so that the airbag 35 is smoothly unfolded. The storage box 321 is used to store the airbag 35, and the oxygen inside the airbag 35 is slowly released into the electric wheelchair 1 through the exhaust pipe 36. When the patient faints, some of the oxygen is discharged through the whistle 37, thereby making a whistle to alert the surrounding people and avoid accidents to the patient. When the guide wheel 324 slides upward, it hits the top rod 6, thereby pushing the wedge block 5, pushing the pressure rod 491, and the third spring 493 is stretched. The pressure rod 491 is separated from the top of the slider 492, and the slider 492 releases the limit on the moving rod 42. Under the pull of the rubber band 494, the moving rod 42 is pulled downward to slide, thereby pulling the shielding roll 48 to release, and the volute spring 495 is compressed. The shielding roll 48 is unfolded along the arc groove 41, thereby shielding the head to prevent oxygen diffusion and playing a protective role. Afterwards, the moving rod 42 can be reset by pushing it, and the volute spring 495 can retract the shielding roll 48. When the third spring 493 contracts, the pressure rod 491 is pulled to reset, thereby pushing the slider 492 to limit the moving rod 42, which is convenient for working again.

[0053] When the patient stands, the backrest 22 moves up, and the rack 47 moves up with it, driving the gear 46 to rotate and the seat 24 to rotate downward, thereby avoiding affecting the patient's walking. The rack 47 has a certain length, and the rack 47 continues to move upward and disengages from the gear 46. When the patient needs to sit down, the rack 47 moves downward and can re-engage with the gear 46, thereby driving the gear 46 and the seat 24 to rotate and reset. The seat 24 is supported by the gear 46 and the rack 47. When the patient is training to stand, the seat 24 is vertically downward, and the patient can lift his feet and place them on the pressing plate 45. By stepping on the pressing plate 45 downward, the pressing plate 45 slides through the sliding rod 43, and the second spring 44 is compressed, thereby obstructing the legs, so that the legs are exercised and the patient's lower limb rehabilitation is promoted.

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
