Title: Innovations by James W. Poitras

Introduction

James W. Poitras is an accomplished inventor based in St. Cloud, Florida. He holds three patents that showcase his expertise in fluid pump technology. His innovative designs have contributed significantly to advancements in this field.

Latest Patents

One of his latest patents is the "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 components are configured as an integral pump assembly. The system also incorporates a linear motor with a magnet and a coil, allowing for movement in relation to the coil, which has an electrical input. Additionally, a control housing is rigidly coupled to the linear motor, and a controller system defines an electrical waveform to facilitate the desired operation of the diaphragm. The integral pump assembly is designed to be removably coupled to the control housing, enhancing its versatility.

Another significant patent is the "Diaphragm Assembly for a Pulsatile Fluid Pump." This assembly features an edge-mounted flexible diaphragm that operates cyclically between diastole and systole modes. It includes a systolic distribution brace that cups a portion of the diaphragm's outside surface and a diastolic plate embedded within the diaphragm. During the systole mode, force is applied across the systolic distribution brace, imparting tension around its periphery. Conversely, during the diastole mode, force is applied across the diastolic plate, creating tension around it.
