For evaluation of rescue skill, or the early detection of the patient in a medical institution, quantification of pains is important. This paper describes techniques, which are purposed of evaluation of pains, based on human's feeling characteristics. The mechanism of a pain was investigated in order to attain quantification of pains. In the mechanism of pains, a receptor plays the role of a sensor. Accordingly, the neurotransmission model based on the characteristic of receptor is proposed.
