Submersible valve for a breast milk collection device with self contained reservoir
The present invention is an improved valve system for a naturally shaped and hands-free human breast milk collection device that fits into a mother's existing nursing or standard brassiere. The invention comprises a submersible valve system within a breast milk collection device, which can significantly increase the breast milk collection capacity of the device without increasing the overall size of the device.
1. A breast milk collection device, comprising:
a funnel having a wide end adapted to receive a woman's breast therein and a narrow end opposite said receiving end, said narrow end forming a drip tube, said drip tube extending forwardly from said narrow end;
a distal end of said drip tube having an aperture adjacent the distal end;
a reservoir enclosing said funnel to form a single unit with said funnel, an internal volume of said reservoir adapted to receive breast milk through said aperture of said drip tube;
cyclical application and relief of said vacuum pressure adapted to encourage the expression of breast milk from said breast;
said cycle portion relieving said vacuum pressure adapted to allow the capture and collection of said breast milk in said reservoir;
a valve assembly in communication with said aperture in said distal end of said drip tube;
said valve assembly including a valve element extending into said reservoir, said valve element adapted to be submerged in said breast milk when the level of said milk reaches and exceeds the position of said valve element in said reservoir, said valve element closing under the force of fluid pressure exerted by the milk on the valve element;
said valve assembly includes a sleeve removably mounted over said drip tube;
said sleeve having a second aperture that aligns with said aperture in said drip tube when said sleeve is mounted on said drip tube; and
said aperture in said drip tube and said second aperture in said sleeve communicating between said drip tube and said valve element.
2. The breast milk collection device of claim 1 , wherein:
said valve assembly includes a valve mounting assembly having an interior chamber extending between said aligned aperture in said drip tube and said second aperture in said sleeve, and said valve element, said interior chamber adapted to convey breast milk from said aligned apertures in said drip tube and said sleeve to said valve element.
3. The breast milk collection device of claim 1 , wherein:
said valve element opens during said cycle portion relieving vacuum pressure in said drip tube, said opening of said valve element adapted to allow milk to advance from said drip tube through said interior chamber and into said reservoir.
