Abstract: A vacuum pump includes a hollow container that has a vacuum port and internal chamber walls. The vacuum port opens to an exterior of the container and the chamber walls define chambers that are in fluid communication with the vacuum port. There are flexible bladders disposed in the chambers. The flexible bladders include vents that open through the container to the exterior. A plunger in the container includes arms that extend into the chambers such that each of the flexible bladders is situated between one of the arms and one of the chamber walls. The plunger is moveable between a home position and an upstroke position to compress and deflate the flexible bladders via the vents and thereby change the volume of the flexible bladders. The change in the volume draws a vacuum through the vacuum port.

Abstract: Dispensing devices and systems for dispensing materials into a host vessel, optionally containing a host substance, are provided. The dispensing devices are removably attachable, in whole or in part, to a host vessel such as a water bottle or an alcohol bottle. The dispensing devices generally include a rotating capsule (perhaps with a quantity of flavor or nutritional supplements in the capsule) that can be rotated to a position to dispense the contents of the capsule into the host vessel. Depending upon configuration, the act of dispensing may involve squeezing, shaking, or the simple passive step of permitting gravity to act on the contents of the capsule.

Abstract: A position-assisting device for milk expression includes an upright body wedge pillow that defines a back side that has an armrest, a front user-engagement side that is sloped back, lateral sides, and a bottom side. The upright body wedge pillow has an upper head-rest section and an interior cavity that has a front face that opens to the front user-engagement side so as to be able to receive a woman's breasts for milk expression. There are breast pumps located in the interior cavity for milk expression.

Abstract: A ring has an open top side and side walls that circumscribe a central region for receiving a phototherapy subject. The side walls include a work surface that is configured to receive visible light through the open top side and reflect the visible light toward the central region for phototherapy. The work surface includes a first surface that is a diffuse reflector and a second surface that is a specular reflector.
