US Patent:
20030050555, Mar 13, 2003
Apr 3, 2002
Appl. No.:
Richard Critchlow - Oakmont PA,
Charles Mutschler - Oakmont PA,
John Shearer - Herminie PA,
John Gardner - Wexford PA,
Joelle Rudnick - Moon Township PA,
Timothy Maiese - Cranberry Township PA,
Dennis Presky - Washington PA,
Michael Pogozelec - Cranberry Township PA,
John Rihn - Glenshaw PA,
International Classification:
US Classification:
An improved magnetic resonance imaging (MRI) injection system exhibits decreased electromagnetic interference (EMI) and improved mobility. The injector apparatus of the injection system includes a head assembly with at least one drive piston and a base assembly including the motor control circuitry and drive motors necessary to control the injector. The electronics in the base assembly are designed to reduce EMI with the magnetic field of the MRI system by employing Faraday cages and various circuit design and filtering techniques. The head assembly of the injector apparatus may also include a hand switch for local control of the injector.

A pressure demand regulator assembly for use with a breathing apparatus having a valve assembly that includes an inlet for connection to a source of breathing gas, an outlet for connection to a facepiece to provide breathing gas to the user and an actuator for controlling the flow of breathing gas between the inlet and the outlet in response to the user's respiration. The regulator assembly further includes a flexible elastomeric diaphragm in operative connection with the actuator. The diaphragm is exposed to ambient pressure on a first side thereof and exposed to a positive pressure within the facepiece on a second side thereof. The regulator assembly also includes an impermeable and flexible shield that seals the first side of the diaphragm from certain toxic substances in the ambient atmosphere while allowing the first side of the diaphragm to experience ambient pressure, such that the flexible shield moves along with the diaphragm during respiration without dampening the movement of the diaphragm during respiration of the user.
