Abstract: A concealed apparatus for hands free breast milk pumping and collection includes one or more low profile nipple caps held in place beneath a support brassiere or other minimally conspicuous confinement. The system permits substantially concealed, hands free breast pumping in a public environment without any remarkable change in the user's visible appearance. Milk is expressed from the breasts through novel, low profile nipple caps linked to a membranous collection reservoir which is optionally designed for milk storage and delivery to the infant user.

Abstract: A concealed apparatus for hands free breast milk pumping and storage includes one or more low profile nipple caps held in place beneath a support brassiere. The system permits concealed, hands free breast pumping in a public environment without any remarkable change in the user's visible appearance. Milk is expressed from the breasts through novel, low profile nipple caps linked to a reservoir via a milk storage conduit. A vacuum is applied to the storage reservoir by any suitable means such as an electric or manual vacuum pump. Suction is thus conveyed through related system components to express milk from the breasts and draw it into the storage reservoir, while being essentially unobserved by others.

Abstract: An artificial infant feeding nipple is disclosed comprising a hollow tubular fluid conduit having first and second open ends and a substantially transverse membrane closing the conduit. In the preferred embodiment, the membrane is perforated by a plurality of minimal diameter fluid apertures fully penetrating the membrane and extending beyond one face of the membrane within integrally formed hollow nubs having closed ends. Each closure nub is removable to permit fluid flow through the related aperture. Additionally, the recessed membrane provides reinforcing against collapse of the nipple tube while permitting the delivery end of the nipple to be plugged to prevent leakage when not in use.

Abstract: A linear double acting reciprocating fluid pump is disclosed with novel anchoring means to remotely secure the pump down hole in deep well applications. The multiple piston pump may be cable operated or directly driven. Using the related remote pump lock in deep well applications, the well casing can double as a discharge conduit. The pump comprises a single tubular barrel containing opposing reciprocating pistons, each piston carrying ample fluid ports with binary valves. Mechanical linkages within the pump barrel alternately reverse opposing pistons causing them to converge and diverge, thus providing a substantially steady fluid discharge and a relatively level demand on the prime mover.

Abstract: The present infant feeding container attempts to simulate as much as possible the sensation of a mother's breast, avoiding many of the drawbacks attendant with conventional artificial means of breast feeding. The container is ideally breast-shaped and fabricated of a resilient material resembling a natural breast. Having a wider base than elongate cylindrical bottles of equal volume, a more stable container is provided. Included is a rack suitable for holding the container for content heating and sterilization. The improved sensory experience facilitated by these innovations is expected to far more closely approximate the experience of natural breast feeding and some of the benefits attendant thereto.
