PROBLEM TO BE SOLVED: To provide a blood circulation simulator that comprises a simulated atrium and is capable of accurately simulating, with a simple configuration, a blood circulation system.SOLUTION: A blood circulation simulator comprising a simulated atrium circulates simulated blood in a circulation flow passage. The blood circulation simulator includes: a simulated vein 23 that is provided in the circulation flow passage and stores simulated blood a simulated right atrium 11 an artificial valve 12 provided downstream of the simulated right atrium 11 a simulated right ventricle 13 provided downstream of the artificial valve 12 an artificial valve 14 provided downstream of the simulated right ventricle 13 and a simulated pulmonary artery 15 provided downstream of the artificial valve 14. The simulated right atrium 11 comprises: a housing an elastic diaphragm for dividing the inside of the housing into an air room and a liquid room and an inflow port and an outflow port for the simulated blood that communicate with the liquid room. The blood circulation simulator includes drive control means (driver 40, controller 50) for deforming the diaphragm by performing supply and exhaust of air to/from the air room, and making a pulsating flow of the simulated blood to be discharged from the outflow port by using variation in volume of the liquid room.COPYRIGHT: (C)2016,JPO&INPIT【課題】簡単な構成で、高精度に血液循環系を模擬することができる、模擬心房を備える血液循環模擬装置を提供する。【解決手段】循環流路内で模擬血液を循環させる、模擬心房を備える血液循環模擬装置であって、循環流路に設けられ、模擬血液を貯蔵する模擬静脈23と、模擬右心房11と、模擬右心房11の下流側に設けられた人工弁12と、人工弁12の下流側に設けられた模擬右心室13と、模擬右心室13の下流側に設けられた人工弁14と、人工弁14の下流側に設けられた模擬肺動脈15と、を有する。模擬右心房11は、ハウジングと、ハウジング内を空気室と液体室に区画する弾性のダイヤフラムと、液体室に連通する模擬血液の流入口および流出口と、を備える。血液循環模擬装置は、空気室へのエアの給排気によりダイヤフラムを変形させ、液体室の容積変化により模擬血液の脈流を流出口から吐出させる駆動制御手段(駆動装置40,制御部50)を有する。【選択図】図1
