Abstract: A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.

Abstract: A decontamination system for victims of chemical, biological, radiological, or other harmful exposure. The system effectively isolates a contaminated patient during a gross washing process and provides the highest level of protection to unit operators that may be dressed in street clothes. The system comprises an isolation apparatus, a washing chamber, an output enclosure, a method of passing a non-ambulatory patient through the system and a waste collection system. The parts of the system may function together as a single, integral unit for mass decontamination at the site of exposure. Further, the system may be used for non-ambulatory and ambulatory humans and/or animals and possibly equipment and other objects.
