Abstract: A breast pump device and associated methods for extracting breast milk are disclosed. A pump head comprises an external shell with an elastic membrane disposed and bonded therein to define at least one hermetically sealed chamber. Manipulation of the elastic membrane, for example, by adjusting suction or pressure in the sealed chamber or within an interior volume defined by the elastic membrane permits radial mechanical compression (positive pressure) to be applied to a nipple positioned in the pump head to simulate compression of the nipple by the infant's tongue and simultaneously permits axial hydraulic or pneumatic suction (negative pressure) to be applied to the nipple to simulate the infant's minimum intra-oral vacuum. The breast pump device of the present invention can generate these simultaneous compressions and suctions with a single vacuum source, which may be an electric pump or a hand-operated mechanical pump.

Abstract: Improved devices and methods for the expression of milk from a breast are disclosed herein. A device for expressing breast milk may comprise a breast interface including a flange configured to engage a breast and fluidly seal thereagainst, and an actuatable assembly operably coupled to the breast interface and configured to apply vacuum pressure at the breast interface. The breast interface may be configured to apply anterior compression to an anterior portion of the breast when the actuatable assembly is actuated. The flange may be configured to apply posterior compression to a posterior portion of the breast when the actuatable assembly is actuated. The posterior compression can help improve the efficiency of milk expression by reducing the retrograde flow of milk.

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 iontophoretic drug delivery system of the present invention includes a controller interconnectable with a drug-filled patch. The controller includes electronic circuitry which monitors and controls the supply of electrical current to the drug-filled patch during delivery of at least one drug, and the electronic circuitry includes a circuit for causing a voltage step in a battery of a plurality of serially-connected cells. Specifically, the circuit causes one or more of the cells to discharge through a resistor at a higher rate than the other cells, thus producing a voltage step when the faster discharging cell dies before the other cells. A reverse-biased diode is connected in parallel to the faster discharging cell to cause the current to bypass the faster discharging cell after it has died, thus preventing it from reverse charging. This circuitry may be controlled to adjust the higher rate of discharge, and thus the time of occurrence of the voltage step.
