Piezoelectric monoactuator peristaltic micropump

The invention solves the technical problem of how to realize peristaltic micropump with a single piezoelectric actuator and enable compatibility with conventional single-phase drivers, while maintaining all the benefits of currently available peristaltic micropumps (simple design and fabrication, low cost, purity and reliability). The absence of valves and low operating frequency (typically around 100 Hz) prevent high fluid velocities and inhibit cavitation. Micropump according to the invention is self-priming and bubble tolerant.

Piezoelectric microcylinder pump

The invention solves micropump technical problem of how to ensure maximum flow-rate and back-pressure performance as well as maximum reliability and long-term stability at small device dimensions. Innovative central cylinder valve positioned at membrane maximum deformation point enables realization of large micropump chamber which greatly improves flow-rate and backpressure performance. Moreover, innovation increases system compression ratio which results in micropump self-priming ability and bubble tolerance.

Photoplethysmograph for the intraoperative attachment above optical channel with monitoring function of the optic nerve microcirculation, and measurement method for non-invasive intraoperative monitoring of the optic nerve microcirculation as additional help to neurosurgeon for patient protection from potential damage of the eyesight during surgery

The invention solves the design and fabrication of narrowly dedicated surgical photoplethysmograph suitable for interoperative attachment above optical channel. The invention is used for non-invasive microcirculation monitoring of the optic nerve. The device’s real-time analysis of measured photoplethysmographic waveform provides a neurosurgeon a feedback about the adequacy of its mechanical manipulation of the optic nerve. By such, the invention protects patient’s vision from potential damage due to inevitable surgical procedure.
