Description

Technical Field

[0001] The invention belongs to the technical field of surgical instruments, and specifically refers to a multifunctional neurology patient rehabilitation device. Background Art

[0002] The nervous system is composed of the brain, spinal cord and peripheral nerves. It mainly diagnoses and treats cerebrovascular diseases (cerebral infarction, cerebral hemorrhage), migraine, brain inflammatory diseases (encephalitis, meningitis), myelitis, epilepsy, dementia, neurodegenerative diseases, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy (numbness and weakness of the limbs) and myasthenia gravis.

[0003] During the rehabilitation stage at the later stage of treatment, neurology patients need to exercise various joints of the body to prevent joint spasms and stiffness and reduce sequelae. Since it is inconvenient for patients to exercise actively, caregivers or family members are needed to assist patients in exercise. The caregivers hold the patient's joints and perform movements such as turning and rotating. The problem with this method is that it requires additional manual services; service personnel can only exercise one part at a time and cannot exercise multiple parts at the same time; manual operation makes it difficult to take into account all joints of the body; and over time, service personnel will feel tired, and the effect of exercise will decline. In addition, service personnel cannot exercise according to the patient's own intentions. If the speed and amplitude of the exercise are not appropriate, it may cause discomfort to the patient's body and affect the patient's experience. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a multifunctional neurological patient rehabilitation device to solve the problems in the prior art that the range of movement of the patient assisted by the caregiver is limited, the whole body cannot move synchronously, and the patient cannot control the movement by himself.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a multifunctional neurology patient rehabilitation device, comprising:

[0006] An exercise bed, wherein the exercise bed is an adjustable bed, wherein one end of the exercise bed is a fixed end, and the other end is an adjustable end, wherein the adjustable end has a rotation and angle adjustment function, so as to adjust the patient to a suitable posture and assist the patient to stand up or lie flat;

[0007] The upper limb exercise mechanism is located at the adjustment end of the exercise bed and is symmetrically arranged in two groups, which are used to drive the two arms to perform joint movements;

[0008] The lower limb exercise mechanism is located at the fixed end of the exercise bed and is symmetrically arranged in two groups, which are used to drive the two legs to perform joint movements;

[0009] The hand exercise mechanism is arranged on the upper limb exercise mechanism and is used to drive the hand joints to move.

[0010] Furthermore, the upper limb exercise mechanism includes a driving body, a first arm, and a second arm. The driving body is arranged on the adjustment end of the exercise bed, the first arm is rotatably arranged on the driving body, and the second arm is rotatably arranged on the first arm.
