Description

Technical Field

[0001] The present invention relates to an autonomous upper limb training aid for avoiding trunk compensation, which relates to an aid for avoiding trunk compensation in stroke patients during the process of autonomous upper limb training. It belongs to the technical field of medical devices, and particularly relates to a training aid for hemiplegic patients that can continuously monitor the patient's forward compensation behavior and avoid the patient's trunk rotation and backward compensation during the process of autonomous upper limb training, without the need for manual supervision of training. Background Art

[0002] Hemiplegia is the most common functional disorder in stroke patients. It refers to the paralysis of the upper and lower limbs on the same side. It is caused by damage to the vertebral tract on one side and is often accompanied by extrapyramidal damage. The upper limb muscle weakness, muscle spasm and coordinated contraction of the shoulder abductor muscles and elbow flexor muscles, shoulder adductor muscles and elbow extensor muscles caused by hemiplegia often lead to abnormal upper limb movements. Upper limb autonomous training generally includes shoulder flexion training, shoulder horizontal adduction, horizontal abduction training, elbow flexion training, and wrist flexion, extension, radial deviation, ulnar deviation, left and right rotation training, etc. It can play a good role in resisting spasms, preventing joint contracture and muscle atrophy, and is an important means for patients to restore upper limb motor ability and improve abnormal upper limb movements. However, stroke patients often experience trunk proxy training. The phenomenon of trunk compensation, that is, patients habitually use trunk rotation, forward leaning and backward leaning and other muscle and joint movements to assist upper limb movements. Trunk compensation will make the patient's upper limb training inadequate and insufficient, reduce the training effect, and the patient's upper limb function speed is slow. In order to eliminate trunk compensation, patients need to be supervised by nursing staff when they are doing autonomous upper limb training. When the patient's trunk is leaning forward, leaning backward or rotating to compensate, the patient should be reminded to correct it in time. The nursing staff needs to pay attention to the patient's training situation at all times, which is more troublesome. In addition, since the patient's upper limb training is a continuous movement process, the patient's trunk compensatory movements with smaller amplitudes during the training process are difficult for the nursing staff to quickly capture with the naked eye, so they cannot remind the patient to correct it in time, which reduces the patient's training effect. Summary of the Invention

This device continuously monitors the patient's forward leaning compensatory behavior through pressure transmitted by a support rod, and prevents trunk rotation and backward leaning through an anti-rotation baffle in conjunction with the training chair body.

[0071] The rotation compensation blocking assembly is composed of a baffle mounting boss 6, a rotating shaft mounting hole 7, a rotating shaft 8, a limit block 9 and an anti-rotation baffle 11.

[0072] The baffle mounting boss 6 is placed on the training chair body 1 and is located at the intersection of the support seat and the anti-tilt backrest. A rotating shaft mounting hole 7 is opened on the baffle mounting boss 6. One end of the rotating shaft 8 is rotatably placed in the rotating shaft mounting hole 7, and the other end extends out of the rotating shaft mounting hole 7.

[0073] One end of the anti-rotation baffle 11 is connected to the other end of the rotating shaft 8.

[0074] Preferably, the other end of the anti-rotation baffle 11 is an arc-shaped structure.

[0075] The limit block 9 is placed on the baffle mounting boss 6.

[0076] Preferably, the limit stopper 9 is located below the anti-rotation baffle 11;

[0077] When in use, the patient sits on the training chair body 1 and rotates the anti-rotation baffle 11 so that the arc-shaped part of the anti-rotation baffle 11 is stuck on the patient's waist. At this time, the patient's back rests on the anti-tilt backrest, and the support rod 4 is forced to slide toward the bottom of the pressure sensor mounting cylinder 14, thereby pushing the support spring 15 to compress. The pressure sensor 16 is compressed to generate a pressure signal and transmit the pressure signal to the signal converter. The signal converter converts the pressure signal into a digital signal and transmits it to the data processor 12. The data processor 12 records it as initial pressure data, and the patient begins to perform upper limb autonomous training. During the training process, The data processor 12 continuously receives the pressure data sensed by the pressure sensor 16 and compares it with the initial pressure data. When the pressure data during the patient's training process becomes smaller than the initial pressure data, it indicates that the patient has a forward leaning compensation behavior of the trunk. The data processor 12 then sends a signal to the controller 13. After receiving the signal, the controller 13 controls the sound and light alarm 5 to emit a sound to promptly remind the patient to correct the training posture. At the same time, during the patient's training process, the anti-rotation baffle 11 cooperates with the anti-backward tilt backrest to prevent the patient's trunk from performing rotation compensation and backward tilt compensation, thereby affecting the training effect of the upper limbs. Example 2

[0078] The difference between this embodiment and embodiment 1 is that the other end of the support rod 4 is connected to a curved support plate 17, and the curved support plate 17 is a long strip structure. The connection between the curved support plate 17 and the support rod 4 is close to the upper part of the curved support plate 17, the convex surface of the curved support plate 17 is connected to the support rod 4, and a silicone pad is provided on the concave surface of the curved support plate 17; when in use, the curved support plate 17 can increase the contact area between the patient's back and the support rod 4, disperse the support force received by the patient's back when leaning on the anti-tilt backrest, and avoid the patient's discomfort caused by excessive force on the back point, thereby causing the patient's back to unconsciously lean forward and increase the number of forward compensations; Example 3

[0079] The difference between this embodiment and embodiment 2 is that an elastic connecting belt 18 is placed between two adjacent arc-surface supporting plates 17. There are two groups of elastic connecting belts 18, which are respectively close to the two ends of the arc-surface supporting plates 17. The thickness of the elastic connecting belt 18 is the same as that of the arc-surface supporting plates 17. When in use, the elastic connecting belt 18 can increase the contact area between the arc-surface supporting plates 17 and the patient's back without affecting the independent movement of each arc-surface supporting plate 17, thereby improving the patient's comfort during training. Example 4

[0080] The difference between this embodiment and the first embodiment is that the anti-rotation baffle 11 is replaced by a telescopic anti-rotation baffle 19, one end of which is connected to the other end of the rotating shaft 8, and the other end of the telescopic anti-rotation baffle 19 is an arc-shaped structure, and a limit block 9 is placed on the baffle mounting boss 6, and the limit block 9 is located below the telescopic anti-rotation baffle 19; when in use, the length of the telescopic anti-rotation baffle 19 can be adjusted, which can prevent patients of different body shapes from compensating for trunk rotation and backward tilt during training, and has a wider range of uses; Example 5

[0081] The difference between this embodiment and the first embodiment is that an anti-tilt baffle 21 is provided on the anti-rotation baffle 11. The anti-tilt baffle 21 has an arc-shaped structure and is provided with a plurality of hollow grooves 20. The plurality of hollow grooves 20 are arranged equidistantly along the length of the anti-tilt baffle 21. When in use, the anti-tilt baffle 21 can prevent the patient's waist from tilting forward during the patient's independent upper limb training. The arc-shaped structure can better fit the patient's waist, and the hollow grooves 20 can reduce the weight of the anti-tilt baffle 21.

[0082] The design of the rotation axis mounting hole 7 cooperating with the limit block 9 to limit the anti-rotation baffle 11 can make the anti-rotation limit baffle cross the patient's waist after the patient sits on the training chair body 1, and limit the patient's waist through the arc-shaped hook, preventing the patient from generating trunk rotation compensation during the autonomous upper limb training;

[0083] The support rod 4 cooperates with the anti-rotation baffle 11 to monitor and pre-eliminate the compensatory movements of the patient's back and waist during the patient's autonomous upper limb training, so that the patient's upper limbs are fully trained and the training effect is improved;

[0084] The backrest groove 2 cooperates with the seat groove 10 to limit the patient's torso, so that the patient's torso sinks into the training chair body 1 during the upper limb autonomous training, providing more stable support for the patient;

[0085] The support rod 4 cooperates with the support spring 15 to support the patient's back, and can convert the support force of the patient's back against the anti-tilt backrest into the pressure of the pressure sensor 16, so that the data processor 12 can monitor whether the patient has a forward leaning compensation during the autonomous upper limb training through the pressure change, so as to promptly remind the patient to correct the posture;

[0086] The support rod limiting hole 3 cooperates with the pressure sensor mounting tube 14 to limit the support rod 4 when the support rod 4 is supported by the patient's back and slides back and forth in the pressure sensor mounting tube 14, thereby preventing the support rod 4 from shaking and affecting the pressure monitoring of the pressure sensor (16);

[0087] The other end of the support rod 4 is an arc-shaped structure, and a rubber ball is placed on the other end of the support rod 4 to form a buffer between the support rod 4 and the patient's back, thereby preventing the hard end of the support rod 4 from continuously contacting the patient's back during the patient's upper limb autonomous training and causing injury;

[0088] The inner diameter of the rubber ball is larger than the diameter of the support rod limiting hole 3, which can limit the support rod 4 and prevent the support rod 4 from completely entering the pressure sensor mounting cylinder 14 under the support of the patient's back, thereby affecting the continuous monitoring of the patient's forward leaning compensation movement;

[0089] The purpose is to continuously monitor the patient's forward leaning compensatory behavior without the need for manual supervision of training, and to timely monitor and pre-eliminate the patient's trunk compensatory behavior with a smaller range of motion during the patient's upper limb autonomous training.

[0090] It should be noted that, unless otherwise expressly specified or limited, the terms "placed in," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections such as hemming, rivet connection, pin connection, adhesive connection, and welding connection; detachable connections such as threaded connection, snap connection, and hinge connection; or integral connection; electrical connection; direct connection; indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0091] It should be further pointed out that, when describing the above specific embodiments, for the sake of simplicity and clarity, only the differences between them and other embodiments are described, but those skilled in the art should know that the above specific embodiments.
