PROBLEM TO BE SOLVED: To attain a device for measuring brain retraction pressure which can directly measure the retraction pressure, can also secure a visual field and a space, while maintaining the same shape and size of a conventional cerebral spatula, and moreover dispenses with correction due to the effect of heat.SOLUTION: The device for measuring the brain retraction pressure includes a cerebral spatula with a pressure sensor which is formed by embedding/adhereing a film-like pressure sensor of about 0.2 mm thick in/to a groove cut in one side of the cerebral spatula and having the thickness and the shape of the pressure sensor, and a measuring device which is equipped with a display unit provided for calculating the retraction pressure from a signal coming from the pressure sensor and being converted and for displaying the retraction pressure by a monitor, an alarm unit giving an alarm when this pressure exceeds the one set beforehand, a memory for storing measuring data on the retraction pressure, etc.COPYRIGHT: (C)2013,JPO&INPIT【課題】圧排圧を直接測定することができるとともに、従来の脳ヘラと同一形状及び寸法を維持して視野及び空間を確保することができ、さらには熱の影響による補正も不要な、脳圧排圧測定装置を得る。【解決手段】厚さ約0.2mm程度のフィルム状の感圧センサを当該感圧センサの厚さと形状を有した溝を脳ヘラの片面に切削して埋設及び接着して形成した感圧センサ付脳ヘラと、前記感圧センサから出る信号を変換して圧排圧を算出し、該圧排圧をモニタ表示するための表示器と、予め設定した圧排圧を超えた場合にアラームを発する警報器と、前記圧排圧の測定データを保存するためのメモリ等を具備した測定装置とにて構成する。【選択図】図1
