Title: Innovations by Richard Knight in Venous Drainage Systems
Introduction
Richard Knight is an accomplished inventor based in Huntington Beach, CA (US). He holds two patents that focus on advancements in medical technology, particularly in the field of cardiopulmonary bypass surgery. His innovative designs aim to improve surgical procedures and patient outcomes.
Latest Patents
Knight's latest patents include a vacuum-assisted venous drainage system with rigid housing and flexible reservoir. This system is designed for cardiopulmonary bypass surgery and features both hard and soft shell reservoirs. The technology utilizes a wall vacuum or other sources of negative pressure to create a controlled environment within a sealed hard shell reservoir or a sealed housing surrounding a soft shell reservoir. This negative pressure allows for the use of smaller cannulas, which are suitable for minimally invasive surgery. The design enhances flexibility in the operating room layout and reduces the extracorporeal blood prime volume needed. Additionally, the system incorporates a flexible membrane that expands to contact the blood surface, minimizing blood/air interactions. A moisture trap is also included to reduce environmental contamination, along with a volume sensor for feedback control of the vacuum and circulation pump. Safety features such as a pressure relief valve and a vacuum stabilizer are integral to the system's design.
