PROBLEM TO BE SOLVED: To provide a nerve stimulation device which warns a user of a small flow rate of a liquid.SOLUTION: A nerve stimulation device 1 comprises: a lead part 10 having a fixed part which is formed of an elastic material and biases a blood vessel by being placed in the blood vessel in an elastically deformed state, and an electrode part provided in the fixed part an indwelling sheath 35 which inserts the lead part into a duct line 36a of itself in an advancing/retreating manner, and allows a liquid to flow a flow rate measuring part 45 which is provided in the indwelling sheath, measures the flow rate of the liquid flowing in the duct line of the indwelling sheath, and outputs a measurement result and a warning part 50 for warning a user when the flow rate of the liquid indicated by the measurement result is less than a predetermined flow rate threshold value.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】使用者に液体の流量が少ないことを警告する神経刺激装置を提供する。【解決手段】神経刺激装置1は、弾性を有する材料で形成され、弾性的に変形された状態で血管内に留置されることで血管を付勢する固定部、及び固定部に設けられた電極部を有するリード部10と、自身の管路36a内にリード部を進退可能に挿通するとともに液体を流す留置用シース35と、留置用シースに設けられ、留置用シースの管路内を流れる液体の流量を計測し、計測結果を出力する流量計測部45と、計測結果が表す液体の流量が所定の流量閾値よりも少ないとき警告する警告部50と、を備える。【選択図】図3
