This invention is a transportable organ preservation system that substantially increases the time during which the organ can be maintained viable for successful implantation into a recipient. A chilled oxygenated nutrient solution can be pumped through the vascular bed of the organ after excision of the organ from the donor and during transport. The device of the present invention uses flexible permeable tubing to oxygenate the perfusion fluid while the CO2 produced by the organ diffuses out of the perfusion fluid. One pressurized two-liter “C” cylinder can supply oxygen for up to 34 hours of perfusion time. The device can use a simple electric pump driven by a storage battery to circulate the perfusion fluid through the organ being transported. The vessel containing the organ to be transported can be held at a suitable temperature by a chiller.

A gas generated by an inflator is supplied through a branching pipe to first and second air bags, which are deployed from a side of a seat to a space between an inner surface of a side of a vehicle compartment and an occupant. A one-way valve mounted in the branching pipe permits the gas to move from the second air bag to the first air bag and inhibits a back flow of the gas, whereby the internal pressure in the first air bag can be maintained higher than that in the second air bag, to thereby restrain the occupant's waist more strongly than the occupant's breast. Moreover, the gas generated by the single inflator is diverted by the branching pipe and supplied to the two air bags. Therefore, the two air bags can be deployed while minimizing the number of the inflator.

A system according to this invention for transmitting power hydraulically to and from the wheels of a motor vehicle includes an accumulator containing fluid at relatively high pressure, a reservoir containing fluid at lower pressure, and a pump / motor driveably connected to the wheels and having an inlet, an outlet, and a variable volumetric displacement for pumping fluid between the accumulator and the reservoir.
