Abstract: A multi-functional modular device includes: a shaft; electric motor(s); propeller(s); battery(s); and paddle blade(s) being removably attachable to the shaft for levering of a boat. With the blade(s) attached to the shaft and motor(s) de-energized, the device is usable for manual levering, and with the motor(s) energized, propeller thrust selectively assists in levering to propel the boat. Propeller thrust in a direction opposite to a propulsive direction from levering reduces work required per stroke, reducing the total levering power per stroke. Alternatively, using the thrust in the same direction as propulsive levering increases total propulsive power per stroke, but requires greater strength/work output by the rower/paddler. Removing the blade permits the propeller and motor to be statically submerged and clocked for directional propulsion.

Abstract: An improved suction apparatus, which may be used by health care providers, emergency medical teams, or a corpsmen, to remove debris, fluid and other foreign matter from the airways and/or wounds of injured persons. The suction apparatus which includes: a venturi tube having a forward end, a rear end and an inlet, a valve located on the top rear end portion of the venturi tube, a body for housing at least one can of propellant or compressed gas, an airtight cap, and a trigger mechanism. The improved suction apparatus that forces the propellant passed the inlet of the venturi tube, wherein the inlet is located toward the distal end of the cap.

Abstract: The present invention is directed to an apparatus for cooling, a liquid in a portable container. The apparatus comprises a housing having a top end and a bottom end. The bottom end is adapted to attach to the portable container. A can of compressed gas can be within the housing. The can of compressed gas can have a release valve to expel the compressed gas. A heat exchanger can be around an exterior surface of the can. The heat exchanger can be adapted to absorb heat from a warm liquid.

Abstract: A fluid removal apparatus for patient treatment comprising a tube having a forward end and a rear end. The apparatus further comprises a body having at least one can of a compressed gas therein and an opening for releasing compressed gas. The tube can be attached to the opening in the body. The apparatus is operated by a trigger means attached to the body. The trigger means is adapted to cause gas to be released from the body thereby causing a suction effect at the forward end of the tube by regulating the flow of compressed gas from the cans of compressed gas out of the rear end of the tube.
