発明の名称 (英語) PAIN SENSATION MEASUREMENT DEVICE AND PAIN SENSATION MEASUREMENT METHOD NEW
発明の概要(英語) Provided are an objective pain sensation measurement device and an objective pain sensation measurement method which are capable of detecting pain sensation with high accuracy, which is caused by a certain physical stimulus to a subject, without being influenced by the subjectivity of the subject, and of measuring a degree of the pain sensation. Before the physical stimulus is applied to the subject, a moving average value of skin conductance is stored in advance in a skin conductance initial value memory as a skin conductance initial value. In addition, a change rate of the skin conductance is calculated on the basis of the skin conductance initial value. The pain sensation based on the physical stimulus can be specifically detected and objective measurement of the pain sensation can be implemented by measuring the presence or absence of pain sensation, or the degree of the pain sensation by using the change rate of the skin conductance.
従来技術、競合技術の概要(英語) BACKGROUND ART
To this, objectively observe pain is not present, the doctor and nurse to patient pain perceived as a method of knowing, visual, analog, approximately less than or equal to the scale (Visual Analog Scale, 'VAS') method is used. VAS is, first, to the subject, a scale 10 from 0 in the straight line drawn to be presented. 0 Is no pain, 10 is the most severe pain imaginable is defined as a state. Then, the current subject and the degree of perceived pain oboshiki them the marked 'x' value. VAS that is, based on the observation of the subject to the subjectivity of a method of pain. VAS is satisfied, the subject is a visual, analog, scale method is premised that it can be seen. Therefore, the language understanding capability of the infant, such as the language understanding capability is lost such as dementia patient, such as that embedded in the awareness of the state of the patient in the intensive care unit to be impossible.
Close to the art of the present invention documents the prior art shown in Patent Document 1. Patent Document 1 is, the sedated patient's autonomic nervous system and a method and apparatus for monitoring the disclosed technology.
