Abstract: The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle disposed between the metal generator and the hypohalite generator.

Abstract: A breast pump system for obtaining breast milk is provided. The system sealingly separates the air flow from the breast milk and uses a single air tube for both positive pressure and negative pressure to be applied to a woman's breast. The breast pump can have a piston/cylinder device for generating pressure that allows a user to control suction and cycle time.

Abstract: The invention relates to a method for purifying water by forming in an electrolytic cell molecular halogen, hypohalic acid, hypohalite ions or combinations thereof, from halide ions dissolved in the water; and dissolving one or more soluble metal salts in the water to provide corresponding metal ions. The invention also relates to a system for purifying water, having an electrolytic cell comprising a plurality of electrodes sufficient to electrolytically convert halide ion in the water into molecular halogen, hypohalic acid, or hypohalite ions, or combinations thereof; and a metal generator, which provides concentrations of one or more metals to the water.

Abstract: A breast cup for use with a breast pump for expressing breast milk is provided. The breast cup sealingly separates the air flow from the breast milk, provides a barrier against impingement of the flexible insert by the user's breast and provides a massaging member for facilitating expression of the breast milk.
