Embodiment Construction

[0036] Refer to attached Figure 1-6 , shows a wearable device 10 for finger 5 rehabilitation. The device 10 is in the form of a glove, also known as an EAP glove, generally comprising a fabric material 20 and an electroactive polymer (EAP) matrix cover 30 . The EAP matrix sleeve 30 is operatively connected to the fabric material 20 forming an EAP actuator for the wearer's finger 5 . The EAP matrix cover 30 may be sewn to the fabric material 20 by stitching to operatively connect the EAP matrix cover 30 to the fabric material 20 . The EAP matrix sleeve 30 may be embedded in the fabric material 20 . The fabric material 20 may be cotton, nylon, polyester and spandex. figure 1 describes an EAP glove having an EAP matrix sleeve 30, while Figure 5 An EAP glove with two EAP matrix sleeves 30 is described. The EAP matrix sleeve 30 is positioned such that each segment spans a knuckle.

[0037] Rigid material 40 is used to transmit force from EAP matrix sleeve 30 to the fingerti...

Abstract

The invention relates to a wearable device for finger rehabilitation. The device (10) for daily finger rehabilitation, the device (10) comprising: a textile material (20); and electroactive polymer (EAP) matrix sets (30) operatively connected to the textile material (20) to form an EAP actuator for a finger (5); wherein at least one EAP matrix set (30) corresponds to a finger joint of the finger (5) for movement of the finger about the finger joint. The EAP material is adopted to convert electric energy to mechanical movement so as to provide repeated active auxiliary movement and be used for finger rehabilitation of a paralytic, the wearable device in the invention is advantaged by good flexibility, few consumption energy, and small increase of temperature.

Description

technical field [0001] The present invention relates to a rehabilitation equipment, more specifically, to a wearable device for finger rehabilitation. Background technique [0002] Stroke is the leading cause of permanent disability in adults. Stroke survivors experience upper extremity dysfunction, while distal extremity injuries are common. This problem is significant because proper hand function is critical for unarmed exploration and manipulation of the environment. In addition, loss of hand function is a major cause of impairment in neuromuscular disorders, often preventing effective functional performance and independent participation in daily life. Rehabilitation after a stroke plays an important role in helping stroke victims reduce their uncomfortable symptoms and restore their motor function. Repetition of common movement exercises can help improve a patient's ability to perform a wide range of daily motor tasks. Basically, there are three main types of post-st...
