Abstract: A device includes a casing that has a collapsed state and an expanded state a spring device in the casing, an inlet port connected with the casing, and a breaker connected with the inlet port. The casing is evacuated to define a pressure differential that holds the casing in the collapsed state, and in the collapsed state the casing holds the spring device in a stressed state that has a stored potential energy. The inlet port is sealed to maintain the pressure differential. The breaker operable to open the inlet port and equalize the pressure differential, whereupon the casing releases the spring device from the stressed state to convert the stored potential energy to kinetic energy that moves the casing from the collapsed state to the expanded state.

Abstract: A pump includes a container that has an interior container volume for holding a substance. There is an outlet associated with the interior container volume for discharging the substance. A hollow needle is connected with the outlet. There is a substance driver disposed in the interior container volume. The substance driver has a stored potential energy that is releasable as kinetic energy and, upon release, the substance driver expands against the substance in the interior container volume and thereby discharges the substance through the outlet to the hollow needle.

Abstract: A pump includes a container that has an interior volume for holding a substance. There is at least one outlet that is associated with the interior volume for discharging the substance. A driver is disposed in the interior volume. The driver has a stored potential energy that is releasable as kinetic energy and, upon release, the driver expands against the substance in the interior volume and thereby discharge the substance through the at least one outlet.

Abstract: An autoinjector includes a pump that has a reservoir for holding a medication and an outlet associated with the reservoir for discharging the medication. The autoinjector has a working side at which the medication is deliverable from the pump, and a non-working side opposite the working side. A housing holds the pump and has at least one finger grip proximally located to the working side, in a further embodiment of the foregoing embodiment, the pump includes a button portion operable to mechanically activate an evacuated driver, and the button portion protrudes from the housing on the working side.

Abstract: A device includes a pump body that has at least one variable-size compartment. The pump body is configured to be actuated to change the size of the at least one variable-size compartment. Flexible bladders are disposed in the at least one compartment. At least one common port is fluidly connected with interiors of the flexible bladders. The change in the size of the at least one variable-size compartment either compresses or expands the flexible bladders in unison and thereby, respectively, either expels the interiors through the at least one common port or draws a vacuum into the interiors through the at least one common port.

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: 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.

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 phototherapy device includes at least one flexible sheet that has first and second electrical conduction layers, an electrical insulation layer between the first and second electrical conduction layers, and light emitting diodes (LEDs) disposed along the electrical insulation layer between the first and second electrical conduction layers. The first electrical conduction layer includes a conductive polymer. The electrical conduction layers and the LEDs are part of an electrical circuit in which the LEDs illuminate responsive to an electrical input. There is at least one meter to measure an electrical property of the electrical circuit. A control module is in communication with the meter and configured to adjust the electrical input responsive to the electrical property of the electrical circuit.

Abstract: A photo-treatment device includes a non-opaque treatment substrate and a radiation-collector beside the substrate. The substrate is sized for a person at which radiation is to be emitted from above the substrate. The substrate has a front surface for receiving the person thereon and a back surface. The radiation-collector captures excess radiation peripheral to the substrate and redirects the excess radiation to the back surface of the substrate.

Abstract: A photo-treatment device includes a treatment region that has a front side at which source radiation is to be emitted and an opposite, back side. A plurality of light guides are located beside the treatment region.
