Intravenous catheter apparatus with pressure differential valve
The patent US12029869B2 describes a novel valve design that incorporates an elastomeric member within a housing, featuring a first and second opening. The elastomeric member is characterized by a continuous peripheral wall that creates a sealable contact with the housing, effectively partitioning it into upper and lower sections. This design allows for fluid flow control based on pressure differentials; when a pressure difference is established, the peripheral wall can either deflect to permit fluid flow around the elastomeric member or the slit in the member can open to allow fluid to flow through it. The valve is engineered to maintain an interference fit between the elastomeric member and the housing, ensuring effective sealing and functionality.
Further claims detail additional features of the valve, including the presence of a support member that facilitates fluid communication between the openings, and various configurations of the elastomeric member, such as its shape and thickness. The design also includes provisions for guiding needles through the housing, enhancing its utility in medical applications. The method outlined in the patent emphasizes the controlled passage of liquid in one direction, utilizing pressure differentials to manage fluid flow while preventing reflux. The valve's structure is intended to support cleaning processes and minimize the risk of thrombus or bacterial growth, making it suitable for applications involving bodily fluids. Overall, the patent presents a comprehensive approach to fluid management in a valve system, with multiple configurations and operational methods to enhance performance and reliability.
