Abstract

The invention discloses a myoelectricity pain measurement method and device for clinical use. The method comprises the steps of (1) acquiring an RIII reflex threshold, (2) detecting RIII reflex under electrical stimulation, and (3) judging the threshold of pain. The device comprises a stimulating electrode, a recording electrode, a constant-current stimulator and an RIII detector, wherein the stimulating electrode is electrically connected with the constant-current stimulator, the constant-current stimulator is in data connection with the RIII detector, the recording electrode is in data connection with the RIII detector, and the RIII detector comprises a signal amplifier, a filter, an analog-digital conversion circuit, a memory, a comparator and a judger and is used for recording the output current of the constant-current stimulator, recording the voltage data recorded by the recording electrode, and judging the threshold of pain according to the pain measurement method. The myoelectricity pain measurement method and device for clinical use solve the technical problem that according to an existing clinic pain measurement method, the measurement result is not accurate due to the fact that judgment is made according to subjective pain reporting.

Description

technical field [0001] The invention belongs to the field of medical devices, and more specifically relates to a myoelectric pain measuring device. Background technique [0002] Pain is a complex psychobiological process caused by noxious stimuli inside and outside the body. It is a common symptom of certain clinical diseases. It is not only a physiological feeling type, but also an unpleasant emotion in psychology. Pain is a subjective experience. Quantitative analysis of this subjective feeling is necessary for clinical work. It is directly related to the diagnosis and classification of patients, the selection of treatment methods, the observation of changes in the condition, the evaluation of treatment effects, and the research work on pain. However, the clinical measurement of pain largely depends on the oral dialogue between the patient and the doctor or nurse. There are no instruments and equipment that can quantitatively evaluate the pain intensity, independently and ...
