Title: Innovations by Douglas E Vincent
Introduction
Douglas E Vincent is a notable inventor based in Pelham, NH (US), recognized for his contributions to fluid pump technology. With a total of 12 patents to his name, Vincent has made significant advancements in the field of pulsatile fluid pumps.
Latest Patents
One of his latest inventions is a pulsatile fluid pump system. This system includes a pump-valving assembly with a chamber and a diaphragm assembly that is coupled to the chamber. The diaphragm assembly features a flexible diaphragm, and both the diaphragm assembly and the pump-valving assembly are designed as an integral pump assembly. The system also incorporates a linear motor with a magnet and a coil, where the magnet moves in relation to the coil, which has an electrical input. Additionally, the system includes a control housing that is rigidly coupled to the linear motor, along with a controller system that has an electrical output connected to the coil's electrical input. This controller system defines an electrical waveform at the output to facilitate the desired operation of the diaphragm. The integral pump assembly is designed to be removably coupled to the control housing, and the diaphragm assembly can also be removably coupled to the linear motor. Another significant patent is the diaphragm assembly for a pulsatile fluid pump, which features an edge-mounted flexible diaphragm. This diaphragm is configured to operate cyclically between diastole and systole modes, with a systolic distribution brace and a diastolic plate that work together to apply force and tension to the diaphragm during operation.
