Title: Duane R Mason: Innovator in Surgical Technology
Introduction
Duane R Mason is a notable inventor based in Irvine, CA. He has made significant contributions to the field of surgical technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Mason's latest inventions is the Surgical Fluid Evacuator. This device features a flexible, compressible reservoir that draws a substantially constant vacuum, allowing for uniform removal of fluid from a surgical incision through a wound drain catheter. The design includes a compression spring positioned between a pair of congruent articulated plates, which provides a biasing force to expand the reservoir and create a vacuum. As the reservoir expands, the wing members pivot relative to the central members, decreasing the effective area to which the spring force is applied. This design ensures that the spring force per unit of area remains nearly constant, thereby reducing changes in reservoir vacuum.
Another significant invention by Mason is the Wound Drain Catheter. This catheter consists of a drain portion connected to an outflow tube portion. The drain portion features a central core with multiple T-shaped members projecting from it, forming several lumens with longitudinal grooves for fluid communication with the wound. The uniform cross-sectional area of the drain enhances its strength, preventing breakage during removal from the patient's body. Made from a silicone elastomer with a durometer shore between 40 and 70 shore A, this design allows the drain's cross-sectional area to decrease by at least 30 percent when a pulling force is applied, reducing the gripping force of surrounding tissue.
