Title: Innovations by Leslie Beckwith
Introduction
Leslie Beckwith is an accomplished inventor based in La Mirada, CA (US). He holds a total of 7 patents that showcase his innovative contributions to the field of medical devices, particularly in breast pump technology.
Latest Patents
Among his latest inventions is the "Completely Closed Syringe System." This innovative design features a cap and rigid bottle that transforms an expressed milk syringe from an open system to a closed system. The cap facilitates fluid communication between a breast pump and breast cup, while the rigid bottle is securely attached to the bottom of the cap. The syringe is contained within the bottom under the cap in a sealed environment. The system allows for varying positive vacuum to be applied, drawing milk into the cap and allowing it to flow by gravity into the syringe. This closed system effectively protects a mother's milk from airborne contaminants.
Another significant invention is the "Programmable Electric Breast Pump." This system includes a vacuum pump that is pneumatically coupled to breast cups, along with a vacuum relief valve that bypasses the vacuum pump. A controller receives input from a vacuum level selector and a vacuum rate selector, as well as feedback from a pressure sensor. The controller cycles the relief valve to create a periodic vacuum pulse in the breast cups. This allows users to adjust the strength and frequency of the pulse, mimicking the natural suckling cycle of a nursing infant.
