To provide an irrigation fluid pressure measuring device, etc. capable of reducing the cost of irrigation treatment.SOLUTION: A control device 700 as an irrigation fluid pressure measuring device, includes a reference value acquisition part 701 for acquiring a reference value at a reference time from a pressure sensor 500 for acquiring pressure of an irrigation fluid irrigated through an ablation catheter 100 to be inserted into a body, a normal value acquisition part 702 for acquiring a normal value at a normal time different from the reference time from the pressure sensor 500, and a pressure acquisition part 703 for acquiring the pressure of the irrigation fluid at the normal time based on the difference between the reference value and the normal value. The device further includes an occlusion detection part 704 for detecting occlusion of an irrigation fluid flow path in a state where the pressure acquired by the pressure acquisition part 703 exceeds an occlusion detection threshold.SELECTED DRAWING: Figure 1 【課題】灌注処置のコストを低減できる灌注流体圧測定装置等を提供する。【解決手段】灌注流体圧測定装置としての制御装置７００は、体内に挿入されるアブレーションカテーテル１００を通じて灌注される灌注流体の圧力を取得する圧力センサ５００から、基準時の基準値を取得する基準値取得部７０１と、圧力センサ５００から、基準時と異なる通常時の通常値を取得する通常値取得部７０２と、基準値と通常値の差に基づいて、通常時における灌注流体の圧力を取得する圧力取得部７０３と、を備える。圧力取得部７０３によって取得された圧力が閉塞検出閾値を超えた状態において、灌注流体の流路の閉塞を検出する閉塞検出部７０４を更に備える。【選択図】図１
