Proposes a reconfigured kioritz dm-9 backpack sprayer that will (1) dispense metered volume of pediculicide, (2) employ existing system energy source, (3) access 17 dispersal sites/person, and (4) maintain adequate flow diameters. A design is postulated that incorporates vacuum actuated slide valves, a metering chamber, and nozzle effectiveness. A survey of previous research and testing will be conducted. Required testing will establish blower baselines and determine needed changes, optimum choices of hopper with variable volume, methods of meter actuation, location of metering devices, and amount of heat loss. The flexible elbow nozzle design will feature a functional outlet, maximize cross section, and minimize dispersal area.
