摘要： An implantable, body-driven shunt pump includes a pump body defining a fluid inlet, a fluid outlet and a fluid chamber therebetween; an inlet valve arranged in the fluid inlet, the inlet valve being a one-way valve arranged such that it is operable to allow fluid flow into the fluid chamber and to prevent fluid flow out of the fluid chamber; and an outlet valve arranged in the fluid outlet, the outlet valve being a one-way valve arranged such that it is operable to allow fluid flow out of the fluid chamber and to prevent fluid flow into the fluid chamber. The pump body includes an expandable and contractible component in a portion of the pump body that defines the fluid chamber such that the fluid chamber changes volume in response to a change in pressure of fluid in the fluid chamber.

摘要： An unpowered respiratory protective headset for personal protective equipment and personal protective bodysuits with an unpowered respiratory protective headset, the unpowered respiratory protective headset having a respiratory mask having a flexible mask body having an interface section and defining a mask air inlet and a mask air outlet, an inhalation valve in the mask air inlet and an exhalation valve in the mask air outlet, and a hood having a hood body and a transparent face shield attached to the hood body. The hood has an air inlet and an air outlet and the air inlet, the mask air inlet, the mask air outlet and the air outlet are configured relative to each other to direct air flow across an inner surface of the transparent face shield to prevent or reduce fogging of the transparent face shield during inhalation and exhalation by a subject.
