Document Type and Number:
Japanese Patent JP2799325
Kind Code:
B2
Abstract:
PURPOSE:To test with large quantity and surely a circulatory function supporting device and make it possible to correspond to an increasing demand by providing a duty ratio setting part setting a time allotment on feed and discharge of a specified fluid on each circulatory function supporting device fixed on a fluid controlling part. CONSTITUTION:An input and output port 44d is connected with a display part 44f for the aimed value setting and actuating state of various pumps and regulators set on the front panel, a period setting part 44g, a period display part 44h and 12 three-way solenoid valve controlling parts ch1-ch12, which are each constituted of a duty ratio setting part, a duty ratio display part, a count display part, a duration time display part and a test period setting part as a set. Utilizing stable driving pressures and discharge pressures of the three-way solenoid valves 28a-28l as a pressure source, switching controls of the valves of the three-way solenoid valves are performed. The control system of the driving period is made thereby a unified and single constitution and it is made possible to drive various duty ratios under the control of the period.
