PROBLEM TO BE SOLVED: To provide a device for properly detecting a decrease in blood pressure at an early stage for performing an appropriate recovery treatment, solving the problem that conventionally, it has been difficult to detect a sudden decrease in blood pressure of a patient undergoing a hemodialysis treatment that occurs in a short time by a regular non-invasive blood pressure measurement at a long time interval.SOLUTION: A perspiration sensor body is attached to a patient, and measurement by perspiration amount measuring means is started. By always monitoring the perspiration amount on the forehead of the patient, checking by starting a non-invasive blood pressure meter when an abnormality is detected in the perspiration amount, etc., a decrease in blood pressure is detected at an early stage, and a recovery treatment is performed.COPYRIGHT: (C)2014,JPO&INPIT【課題】従来、短時間で発生する血液透析治療中の患者の血圧急低下を、長時間間隔の定時の非観血式血圧測定で検知することは困難であったので、血圧低下を早期かつ的確に検知し、適切な回復処置に繋げるための装置を提供する。【解決手段】発汗センサ本体を患者に取り付け、発汗量測定手段において測定を開始する。患者前額部の発汗量を常時モニタし、発汗量に異常が認められた時に非観血式血圧計を起動させて確認する等により、血圧低下を早期に発見し、回復処置を実施する。【選択図】図8
