Abstract

The invention relates to a wearable finger detection device based on pressure and electromyographic signals. The device is characterized by comprising a pressure signal collecting fingerstall, a connecting band, an electromyographic collecting finger ring, a signal transmission data cable and a fixing band, wherein the pressure signal collecting fingerstall is matched with the fingertip of a finger to be tested in shape and is connected with the electromyographic collecting finger ring through the connecting band, and the fixing band is arranged on the other side of the electromyographic collecting finger ring; a pressure plate is arranged on the portion, for sensing stress, of the pressure signal collecting fingerstall, and pressure signals are output through the signal transmission data cable; an electrode patch is arranged on the portion, for sensing flexor tendon stress, of the electromyographic collecting finger ring, and flexor tendon stress signals are output through the signal transmission data cable. Pressure signals and electromyographic signals of the finger can be collected and detected at the same time, and the requirement for verifying the authenticity and objectivity of electromyographic signal output by taking a pressure signal detection result as auxiliary data is met.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation detection equipment, and relates to a wearable finger detection equipment based on pressure and myoelectric signals. Background technique [0002] In life and production activities, the contribution of both hands is huge. Among them, the thumb, index finger and middle finger are used the most frequently, and the working tools based on these three fingers are the most, and these three fingers are also the most prone to injury. Among common industrial, agricultural, traffic and life injuries, 25%-30% of cases involve hand injuries. Among them, muscle damage and tactile nerve damage of the thumb, index finger and middle finger account for a large proportion. The symptoms are that the hand is in a semi-clenched fist state, the fingers are difficult or difficult to complete the flat-bending movement, and the clinical manifestations are partial or complete loss of muscle vitality of the flexor pol...
