PROBLEM TO BE SOLVED: To propose a urine detection method for detecting micturition of a nursing-care-receiver/care-receiver by solving problems in which a conventional urine detection system is provided for detecting a situation such as a diaper after urination, and therefore is utilized as post-processing after the urination of the nursing-care-receiver/care-receiver.SOLUTION: At least 2-feeble wireless tags 1, 2 are arranged in an abdomen side and a back side of a nursing-care-receiver/care-receiver, and thereby the urinary volume in the body of the nursing-care-receiver/care-receiver is detected by using communication radio field intensity between these wireless tags 1, 2. When the communication radio field intensity between the wireless tag 1, 2 is high, a decision is made that the urinary volume in the body is less. When the communication radio field intensity is low or the radio field intensity is 0, the decision is made that there is much urinary volume in the body. The bluetooth LE is used as the wireless tags 1, 2, and thereby a urine detection system that is simple and has good connectivity with a network can be constituted.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】従来の尿検知システムは、排尿後のおむつ等の状況を検知するものであったため、被看護者・被介護者の排尿後の後処理として活用するのみであった。被看護者・被介護者の尿意を検出する尿検知方法を提案する。【解決手段】被看護者・被介護者の腹部側及び背中側に少なくとも2つの微弱無線タグ１、２を配置し、これらの無線タグ１，２間における通信電波強度を用いて、被看護者・被介護者の体躯内の尿量を検知する。無線タグ１，２間の通信電波強度が高い場合には、体躯内における尿量は少ないと判断し、通信電波強度が低い場合又は電波強度が０の場合には、体躯内の尿量が多いと判断する。無線タグ１，２として、ブルートゥースＬＥを用いることにより、簡便でネットワークとの接続性も良好な尿検知システムを構成することができる。【選択図】図１
