Introduction

Raymond A Ellestad is a notable inventor based in Rialto, CA (US), recognized for his contributions to the field of pulmonary ventilation. With a total of 4 patents, Ellestad has made significant advancements in medical technology, particularly in the design of ventilators that enhance patient care.

Latest Patents

One of his latest patents is a "Pressure-limited, time-cycled pulmonary ventilation with volume-cycle." This innovative ventilator includes a pressurized gas system that supplies respiratory gas to a patient at a selected inspiratory flow rate. It features an exhalation valve that opens an expiratory flow path in response to a selected inspiratory time period while maintaining a proximal pressure limit. Additionally, it incorporates a volume-cycle override system that actuates the exhalation valve if the patient's tidal volume reaches or exceeds a selected volume limit during the inspiratory time period. This system utilizes a flow sensor to derive a measured tidal volume signal, ensuring precise control over the patient's breathing.

Another significant patent is the "Directional thermistor assist sensing." This invention is a directional sensor designed to detect minimal breathing efforts from patients reliant on mechanical ventilators. It employs a self-heated thermistor assembly mounted in a small diameter sensor tube, allowing for the detection of very feeble efforts to breathe. The system is engineered to signal the ventilator to respond appropriately to the patient's inhalation and exhalation efforts, enhancing the overall functionality of mechanical ventilation.
