- Research topics
-
- ●Development of a hydrodynamically levitated centrifugal blood pump
- We have developed a non-contact-type centrifugal blood pump with hydrodynamic bearings for mechanically circularly assist (MCA). The impeller levitates by means of an original spiral-groove thrust bearing and a journal bearing, without any additional displacement-sensing module or additional complex control circuits. The pump was improved by optimizing the design of the thrust bearing and the radial bearing.
- ●Development of an Ex-Vivo Lung Perfusion (EVLP)
- ●Development of a Miniaturized Mass Flow Meter
●Past study
・Evaluation method for three dimensional regenerated cartilage
・Development of a long-term disposable blood pump
・Development of hydrodynamic bearing for blood pump
・Online Parameter Identification of Systemic Circulation Using Delta-Operator
・Tsukuba-Telemetry System for Continuous Flow Artificial Heart
・An Operating Point Control System For a Continuous-Flow Artificial Heart
