Abstract: An apparatus for discharging pressurized liquids at elevated positions includes a holding adapter, an actuating assembly, and an extension pole. The holding adapter includes first body member for holding a canister of pressurized liquid. The canister has an actuating stem extending from its top end thereof. An actuator nozzle is formed of an annular flange and a cap-like head portion. The head portion is disposed over the actuating stem. A handle portion is formed integrally with the first body member and extending downwardly from the holding adapter. The actuating assembly is telescoped over the canister and the holding adapter and includes a second body member for applying a downward force on the annular flange of the actuating nozzle to activate the actuating for discharging the pressurized liquid therefrom. The extension pole is operatively connected to a distal end of the handle portion and is adjustable to desired elevated positions.

Abstract: The present invention presents a “serverless” medical information system network and method of creating one or more self-assembling and self-monitoring medical device network grids. Several communication node devices form each grid. Each node device may connect to one or more medical instruments, providing the medical instruments access to the network. The invention also includes methods for assembling the tree-like structure of the grid and balancing the load or placement of the nodes across the entire grid and for self-monitoring of the grid, such that the nodes can detect, record, and distribute changes to the status of any node in the grid. In addition, the nodes can provide web services to other computer devices, such as handheld devices.
