Described herein are systems and apparatuses for enhanced comfort through contact pressure reduction. In particular, the systems and apparatuses disclosed herein prevent or otherwise mitigate pressure by actively orienting a patient over an anatomy-specific pressure-mitigating contact surface on which the patient rests. A pressure-mitigating contact portion of the contact surface includes a plurality of independently pressurized chambers configured in a specific geometric pattern that is designed to mitigate contact pressure between a support surface (e.g., bed or chair) and a specific anatomic region of a patient's body when the specific anatomic region of the patient's body is oriented over an epicenter of the geometric pattern. Additionally, a plurality of elevated side support portions and a wedge interconnected on the base material are configured to actively orient the specific anatomic region of the patient's body over the epicenter of the geometric pattern.

An example fluid collection assembly includes a fluid impermeable barrier having a proximal surface and a distal surface opposite the proximal surface. The proximal surface defines an opening. The fluid collection assembly also includes at least one inflation device. The inflation device includes a bladder. The bladder may be adjacent to the distal surface of the fluid impermeable barrier or between a conduit disposed in the chamber and the distal surface. The bladder is configured to switch between a first state and at least a second state. A volume of the bladder is greater when the bladder is the second state than when the bladder is in the first state. Switching the bladder between the first and second states changes a curvature of the at least a portion of the fluid collection assembly.

Introduced here are apparatuses and systems for mitigating contact pressures applied to a human body by the surface of an object, such as a chair, bed, or table. A pressure-mitigation apparatus can include a series of chambers whose pressure can be individually varied. When placed between a patient and a contact surface, the pressure-mitigation apparatus can vary the contact pressure on a specific anatomical region of the patient by controllably inflating and/or deflating one or more cell. Moreover, a pressure-mitigation system can be readily integrated into a conventional treatment regimen for a variety of different conditions.

A water powered system includes a sealed and insulated chamber with an aluminum alloy source; a control unit to selectively expose a predetermined amount of an aluminum alloy to a liquid to generate hydrogen gas; a fuel cell stack to receive hydrogen gas from the hydrogen gas tank and oxygen from the atmosphere, the fuel cell stack generating electricity; and an energy storage device to receive electricity.

A system includes a pump dispensing liquid to a solid alloy to generate hydrogen gas in a sealed chamber; a chamber to store hydrogen gas; and an engine to power a vehicle or a converter coupled to the chamber to power an electronic/electrical device.

Examples relate to systems, devices, and methods for removing fluid from a fluid collection device using a vacuum source operably coupled thereto. The fluid collection devices include urine collection devices having shape memory material that may be selectively shaped to complement the female or male anatomy near the respective urethras.

A wound therapy system includes a dressing sealable over a wound and defining a wound space between the dressing and the wound, tubing fluidly communicable with the wound space, and a canister fluidly communicable with the tubing. The canister, the tubing, and the dressing define a sealed space that includes the wound space. The wound therapy system also includes a therapy unit coupled to the canister. The therapy unit includes a sensor configured to measure a pressure in the sealed space, a valve positioned between the sealed space and a surrounding environment and controllable between an open position and a closed position, and a control circuit. The control circuit is configured to control the valve to alternate between the open position and the closed position to allow airflow through the valve, receive measurements from the sensor, and determine a volume of the wound space based on the measurements.
