US Patent:

20110042597, Feb 24, 2011

Filed:

Aug 18, 2010

Appl. No.:

12/858864

Inventors:

John Christopher Huculak - Mission Viejo CA, US
Brian William McDonnell - Irvine CA, US

International Classification:

F16K 31/02

US Classification:

25112915

Abstract:

A high speed pneumatic valve has a housing enclosing a cavity with an inlet port and an outlet port. A permanently magnetized armature is located in the cavity. The permanently magnetized armature moves between a first, open position and a second, closed position. A coil and magnetic core assembly is located near the armature in the housing. A first voltage applied across the coil results in a magnetic field with a first polarity being induced in the magnetic core thereby attracting the armature toward the magnetic core and away from the outlet port. A second voltage applied across the coil results in a magnetic field with a second, opposite polarity being induced in the magnetic core thereby repelling the armature away from the magnetic core and toward the outlet port.

International Classification:

A61M 5/20

US Classification:

604151

Abstract:

Devices, systems, and associated methods that facilitate the injection and/or aspiration of precisely controlled volumes of fluids at precisely controlled rates are provided. In some implementations, an apparatus may include a syringe and a lead screw connected to a plunger of the syringe. A ratchet gear may be connected to the lead screw. A mechanism may also be included to oscillate a frame in a direction perpendicular to a longitudinal axis of the lead screw such that one or more pawls of the frame engage the teeth of the ratchet gear in a manner that results in rotation of the ratchet gear in a single direction for controlled linear displacement of the plunger.

US Classification:

134 89

Abstract:

In accordance with the present invention, there is provided portable fluid application and rinse apparatus for applying a first fluid and for rinsing with a second fluid. A first storage reservoir retains the first fluid and has an outlet. A first application conduit communicates with the outlet of the first storage reservoir. The first application conduit receives the first fluid from the outlet of the first storage reservoir and dispenses the first fluid therethrough. A first drain pan receives the first fluid. A second storage reservoir retains the second fluid and has an inlet and an outlet. A second application conduit communicates with the outlet of the second storage reservoir. The second application conduit receives the second fluid from the outlet of the second storage reservoir and dispenses the second fluid therethrough. A concentration measuring device measures the concentration of the second fluid.
