  • Patent number: 9662442
    Abstract: The present invention relates to a linear flow regulating apparatus for intravenous infusion, and more particularly, to a flow regulating apparatus which is used in an infusion set for intravenous infusion to regulate the flow rate of a solution injected into a body. To eliminate the difficulties caused by the nonlinearity of conventional flow regulating apparatuses, which regulate flow rates by pressing a solution flow tube to adjust the flow passage area, the linear flow regulating apparatus has a control unit to be put in or taken out along the width of a flow channel unit through which the solution flows when the height and length of the flow channel unit are fixed, and is capable of linearly regulating the flow rate by varying the flow passage area of the flow channel unit by adjusting the width of a flow channel unit.

  • Patent number: 6634433
    Abstract: Disclosed in an inert gas generator to produce a large quantity of inert gas within a short period of time. The inert gas generator comprises: a gas turbine consisting of a starter motor, compressor, combustor and turbine body; an afterburner being connected to an exit of the gas turbine to re-burn gas burned in the combustor and being equipped with a flame stabilizer; a cooling chamber being equipped with spray nozzles to eject water to decrease gas temperature in the afterburner exit; an evaporator set to further cool the gas-steam mixture from the afterburner; a cooling chamber and spray nozzles; an exhaust nozzle to guide the direction of the inert gas-steam mixture of low temperature and oxygen content; and a controller for controlling the starter motor, the fuel pump and combustor. The inert gas generator mounted on a movable vehicle can promptly suppress the fire occurred in various places with least amount cost possible.
