Title: Innovations by Ervin R Harvel

Introduction

Ervin R Harvel is a notable inventor based in Mission Viejo, CA (US). He has made significant contributions to the field of medical devices, particularly in surgical fluid management. With a total of 2 patents, his work demonstrates a commitment to improving surgical procedures and patient care.

Latest Patents

One of Harvel's latest patents is the Surgical Fluid Evacuator. This innovative device features a flexible, compressible reservoir that draws a substantially constant vacuum. This design allows for uniform removal of fluid from a surgical incision through a wound drain catheter. The reservoir includes a compression spring interposed between a pair of congruent articulated plates. The spring 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 mechanism helps maintain a more constant vacuum within the reservoir.

Another significant invention by Harvel 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, the drain allows for a decrease in cross-sectional area by at least 30 percent when a pulling force is applied, reducing the gripping force of surrounding tissue.
