Iwaki, a Japanese chemical pump manufacturer, exhibited the use of pumps at the 7th Japan Medical Device Development and Manufacturing Exhibition (MEDIX 2016) (Tokyo International Convention and Exhibition Center, June 22-24, 2014). A durable test device for the artificial heart "Laboheart NCVC". The device was developed by Ivey and the National Circulatory Disease Research Center of Japan and is currently on sale. The "heart function simulator" using the device is also disclosed this time.
This device reproduces "left ventricle", "aortic artery", "mitral valve" and the like using a pump, a chamber, a check valve, and the like. It constitutes a circulation loop that mimics the heart. A medical device to be evaluated, such as an auxiliary artificial heart, can be connected to the circuit, and a liquid such as distilled water can be introduced. The "left ventricular pressure", "aortic pressure" generated in the circuit, etc. can be measured using a pressure sensor. The unit is also equipped with an electromagnetic flow meter that measures the total pump flow. In addition to assisting the artificial heart, it is also suitable for endurance testing of Balloon Catheter and the like.
The heart function simulator utilizes the pressure measurement function of Laboheart NCVC. Waveforms such as left ventricular pressure and aortic pressure can be evaluated.
