Pain-measuring equipment

Abstract

The invention relates to pain test equipment, which is characterized in that the equipment comprises a hand-hold controller, an irrelevant electrode and an exciting electrode; the hand-hold controller comprises display input equipment, a control circuit and a power supply; the irrelevant electrode and the exciting electrode are connected with the control circuit of the hand-hold controller through conducting wires; the control circuit comprises a singlechip, an A / D sampling circuit, a D / A output circuit, a feedback circuit and a drive circuit; the display input equipment carries out information interaction with the singlechip to set working mode of the singlechip and display control results; the singlechip outputs analog signals to the drive circuit through the D / A output circuit; the drive circuit applies current on the irrelevant electrode and the exciting electrode; and the A / D sampling circuit carries out current sampling on the drive circuit through the feedback circuit and converts the sampled analog signals into digital signals to input the digital signals to the singlechip, thereby carrying out feedback control of the D / A output circuit. The pain test equipment is suitableto carry out pain sense tests for an organism under simple medical conditions, thereby providing reliable foundation for further diagnosis and treatment.

Description

technical field [0001] The invention relates to a medical auxiliary instrument, in particular to a pain measuring device for obtaining quantitative parameters of pain in a human body. Background technique [0002] At present, the clinical examination of sensory nerve fibers in clinical practice is mainly based on the sense of touch, pain and two-point discrimination. Since pain is a subjective feeling, it is difficult to quantitatively measure the degree of pain objectively. At present, most clinical evaluation methods for pain perception are based on patient inquiry and behavioral observation. These evaluation methods are not objectively measured, so it is not only difficult to truly reflect the degree of pain, but also has many interference factors and poor reliability. [0003] In order to accurately judge the degree and scope of pain, a valuable "pain value" table is formulated according to the "pain threshold" and "pain tolerance threshold" of different groups of peopl...
