International Classification:

A62B 1810

US Classification:

12820712, 12820525, 12820621, 12820713, 128912

Abstract:

A respiratory mask having a flexible, mask seal portion for engagement with the face of a user, a gel forehead cushion and a rotatable elbow coupling having integral exhaust ports. The mask seal portion has a thin section which permits the mask to more easily adapt to the contour of the face of the user. The gel forehead cushion provides increased compliancy and resiliency to better adapt to multiple user physical profiles. The elbow coupling includes tapered through holes in a polycarbonate arc piece to provide a quiet passage of gas through the holes.

International Classification:

A61M 5/14

US Classification:

604251

Abstract:

The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.
