Gordon S. Reynolds has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An anticoagulant delivery device forming part of an aspiration wand for use in connection with autologous blood transfusion wherein an anticoagulant is delivered along essentially the entire internal periphery of the aspiration wand in the vicinity of the aspiration tip and intimately mixed with aspirated blood.
Abstract: A self-sustaining rigid body drainage collector including two or more sections each equipped with means for interlocking with another section when snapped together to provide a fluid tight joint; one of said sections having fittings for connection to the patient and to a vacuum line. The collector may be disposed of, empty or full, in an asceptic manner or emptied and reused on the same patient.

Abstract: A catheter assembly for sampling gases in biological tissue in vivo, including a catheter constructed of a hollow tube sheathed in a gas-permeable membrane, and an impermeable barrier between the tube and membrane to define the boundary of a sampling tip. A catheter hub slideably surmounts the catheter and detachably receives a calibration chamber normally surrounding the sampling tip. The method includes purging the calibration chamber with a calibration gas and thereafter removing the calibration chamber and inserting the catheter into the tissue to be sampled.
Abstract: An aspiration wand assembly having an associated metering valve for metering liquid anticoagulant to blood aspirated by the wand. The metering valve includes a flexible diaphragm normally obstructing conduit which transmits anticoagulant from a remote source to the tip of the aspiration wand. An orifice communicates the diaphragm with the interior of the aspiration wand so that various negative pressures in the wand correspondingly draw the diaphragm into any one of a plurality of positions away from the obstructing position.
Abstract: An anticoagulant delivery device forming part of an aspiration wand and method for use in connection with autologous blood transfusion wherein an anticoagulant is delivered to and intimately mixed with aspirated blood in the vicinity of the aspiration tip of the wand.
