Novel portable upper-limb rehabilitation robot

Abstract

The invention discloses a novel portable upper-limb rehabilitation robot which is provided with five degrees of freedom and is capable of driving shoulders, arms, wrists and hands to perform movement rehabilitation simultaneously, being used for single-joint movement rehabilitation and movement rehabilitation of multiple joints at the same time. The novel portable upper-limb rehabilitation robot comprises a direct-current motor, an electric putter drive module, a mechanical-arm execution module, a mechanical-arm length adjustment module, a spacing module and a hand and wrist connection module, the direct-current motor and the electric putter drive module are connected with the mechanical-arm execution module, the mechanical-arm length adjustment module performs adjustment according to the length of the arms of patients, the spacing module guarantees safety during rehabilitation movement, and the hand and wrist connection module guarantees movement of the wrists and are capable of driving the hands to perform rehabilitation training. The novel portable upper-limb rehabilitation robot is simple in structure, light in weight, easy to carry, low in production cost, convenient and reliable to operate and broad in development prospect.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a portable upper limb rehabilitation robot with a limit device, adjustable length of the upper and lower arms, and capable of driving the shoulders, arms, wrists and hands to move at the same time. Background technique [0002] Cardiovascular and cerebrovascular diseases are a serious threat to human beings, especially for middle-aged and elderly people over 50 years old. Even with the most advanced comprehensive treatment, more than half of stroke survivors are still unable to take care of themselves. This situation is particularly prominent with the rapid progress of aging. In view of the increasing incidence of cardiovascular and cerebrovascular diseases, the disadvantages of upper limb rehabilitation training for hemiplegia, and the low treatment efficiency of physiotherapists, develop a method that can restore upper limb mobility, maintain upper limb...

AI Technical Summary

Problems solved by technology

[0003] Some upper limb rehabilitation robots that have been proposed so far mainly carry out functional rehabilitation of the upper limbs by driving the joints of the shoulder and arm. Invention patent "upper limb rehabilitation robot" with application number 201110176549.2 and invention patent "exoskeleton upper limb rehabilitation robot" with patent application number 201010218016.1

In addition, there are a few upper limb rehabilitation robots that consider shoulder, arm and wrist joints at the same time, but the structure is too complex and requires special bracket installation, such as the invention patent "5-DOF exoskeleton upper limb rehabilitation robot" with patent application number 200810064878.6 And the invention patent "exoskeleton wearable upper limb rehabilitation robot" with the patent application number 201110352097.9, etc.
