Title: Roberta L. Callaghan: Innovator in Oral Irrigation Technology

Introduction

Roberta L. Callaghan is a prominent inventor based in Fort Collins, Colorado, known for her significant contributions to oral irrigation technology. With a total of 12 patents to her name, she has made remarkable advancements in the field, particularly in the design and functionality of oral irrigators.

Latest Patents

Among her latest innovations is an oral irrigator that features a handle, a tip, and a pump that is at least partially housed within the handle and fluidly connected to the tip. This innovative pump includes a pump body that defines a pump chamber, an inlet valve that regulates fluid flow into the pump chamber, and an outlet valve that controls fluid flow out of the pump chamber. The design incorporates a piston and a linkage that connects to the piston and the drive shaft of a motor. This linkage translates the rotational movement of the drive shaft into the movement of the piston in both directions within the pump chamber. When the piston moves in one direction, the inlet valve opens, allowing fluid to flow into the pump chamber, while the outlet valve remains closed. Conversely, when the piston moves in the opposite direction, the inlet valve closes, and the outlet valve opens, permitting fluid to flow out of the pump chamber. Another notable patent is an irrigating device with a variable pressure pulse, which includes a reservoir for storing fluid, a tip connected to the reservoir, and a pump that draws fluid from the reservoir and propels it to the tip. This device also features at least one reed valve that regulates fluid between the inlet port or the exhaust port of the pump.
