Embodiment

[0045] A kind of articulated soft rehabilitation robot glove provided according to the present invention comprises:

[0046] Glove body: such as figure 1 , figure 2 , including the palm and the back of the palm, which are used to facilitate the fixation of the fingers and the wearer's hand, and five soft fingers for training the wearer's hand movements; wherein, the soft fingers are mainly divided into a silicone matrix, a layer that limits expansion and strain and the elongation-limiting strain layer. The interior of the silica gel matrix is ​​a hollow structure. When the gas-driven pressure is injected into the matrix, the expansion-limiting layer wrapped on the outer surface of the matrix will prevent the silica gel matrix from becoming thicker due to radial expansion, while limiting The elongation strain layer covers the non-interphalangeal joint parts of the lower half surface (i.e. finger bottom) and the upper half surface (dorsum) of the soft finger, so that only the ...

Abstract

The invention provides a joint type soft rehabilitation robot glove. The joint type soft rehabilitation robot glove comprises a glove body and a control system; the glove body comprises a palm center and palm back part and soft fingers, and each soft finger comprises a silica gel base body, a limiting expansion layer and a limiting extension layer; the control system comprises a sensing module, a control module and an execution module, human hand surface electromyogram signals and finger real-time curvature signals collected by the sensing module are subjected to signal decoding and then transmitted to the control system dominated by Arduino together with air pressure signals output by an electromagnetic valve set, the control system converts control signals into analog voltage signals through a PWM conversion module after operation decision making and transmits the analog voltage signals to the execution module, and the electromagnetic valve set is influenced by the control signals under the condition that an air pump provides driving pressure to provide air pressure required by the soft fingers. The soft exoskeleton glove has the advantages of being good in structural flexibility and motion flexibility, and the wearing safety and comfort can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an articulating soft rehabilitation robot glove. Background technique [0002] The hand is an extension of the brain function. The unique fine sensitivity of the hand makes the hand not only an indispensable labor organ, but also an important sensory organ. Nowadays, our country is gradually entering an aging society. A large part of the elderly population suffers from various degrees of cerebral thrombosis and nervous system diseases, and most of these patients have different degrees of hand motor dysfunction. The training and treatment of the patient's hand through the hand rehabilitation robot can assist the physician to accelerate the recovery of the patient's hand function, thereby causing benign plastic changes in the patient's cerebral cortex. Therefore, hand rehabilitation robots have important practical significance for improving the quality of hand rehabilitati...
