Wearable soft rehabilitation gloves with asymmetric cavity contact enhancement

Abstract

The invention provides a wearable soft rehabilitation glove with asymmetric cavity contact enhancement, comprising: a soft glove body and a software driver, the software driver is used in conjunction with the soft glove body; the software driver includes an upper air cavity composite cloth and an air cavity lower layer composite cloth Composite cloth of the upper layer of the air cavity and the composite cloth of the lower layer of the air cavity are connected by heat and pressure to form an airtight air cavity. The lower layer of the cavity has an asymmetric structure, and the air cavity is folded to form corrugated folds and one side is connected to the composite cloth of the constraining layer. The invention improves the output grip force of the rehabilitation glove through the contact enhancement effect of the asymmetric air cavity and the contact pad, and adopts the asymmetric cavity channel with unequal width up and down to manufacture the driver, which changes the section moment of inertia and improves the output grip force.

Description

technical field [0001] The invention relates to the technical field of soft rehabilitation exoskeleton, in particular to a wearable soft rehabilitation glove with asymmetric cavity contact enhancement. Background technique [0002] Hand motor dysfunction caused by stroke, spinal injury, Parkinson's syndrome, etc. can significantly reduce the patient's daily activities, such as grasping objects, drinking water, etc., thereby reducing the patient's quality of life. The development of rehabilitation robots provides an important tool for rehabilitation training of patients' hand function. [0003] Traditional rigid hand function rehabilitation exoskeletons have disadvantages such as large mass, complex mechanism, and joint dislocation; recently developed soft rehabilitation gloves have improved safety and comfort, but the grip provided by gloves is insufficient, which limits the use of soft rehabilitation gloves in rehabilitation training. and applications in daily life.

Problems solved by technology

[0003] Traditional rigid hand function rehabilitation exoskeletons have disadvantages such as large mass, complex mechanism, and joint dislocation; recently developed soft rehabilitation gloves have improved safety and comfort, but the grip provided by gloves is insufficient, which limits the use of soft rehabilitation gloves in rehabilitation training. and applications in daily life

[0004] After searching, the patent document CN111631904A discloses a semi-wearable palm rehabilitation exoskeleton. The exoskeleton is driven by a hydraulic cylinder, a piston rod, etc. to drive the connecting rod mechanism to drive the fingers to rotate, and can assist the hand in rehabilitation training; but the exoskeleton The quality of the parts is large, the types are many and complex, and the human-machine compatibility of the mechanism is insufficient

[0005] Patent document CN109223430A discloses a wearable software rehabilitation glove and its control method and system, which have better wearing comfort and safety; width, forming a symmetrical cavity; the grip force output by the driver is insufficient, which limits the gripping ability of rehabilitation gloves and the application in rehabilitation training
