Enhanced Check Valve System for Intravenous Sets

An improved check valve system for intravenous sets, featuring innovative designs and mechanisms to enhance fluid flow reliability, reduce contamination risk, and minimize maintenance needs.

The original check valve patent, while effective, has limitations in terms of particulate accumulation and clogging, which can compromise fluid flow and increase the risk of contamination. The new inventive concept addresses these limitations by introducing novel designs and mechanisms that improve fluid flow reliability, reduce contamination risk, and minimize maintenance needs.

The enhanced check valve system comprises a wiping extension with a tapered surface, which facilitates particulate removal from the valve member, thereby improving fluid flow reliability. Additionally, the system features a method for optimizing check valve operation by rotating the valve body and wiping extension relative to the valve member to dislodge particulate, and then returning the valve body and wiping extension to their original position, thereby reducing contamination risk. Furthermore, the system incorporates an integrated filter that captures particulate before they reach the valve member, enhancing fluid purity and reducing maintenance needs. A self-cleaning mechanism is also introduced, where the wiping extension is designed to vibrate at a predetermined frequency to dislodge particulate, minimizing the risk of clogging. Finally, the system features a modular design, comprising interchangeable valve bodies and wiping extensions, allowing for customized configuration and easier maintenance.

The new claims introduce novel designs and mechanisms that are not obvious from the original patent, including the tapered surface on the wiping extension, the rotating and vibrating mechanisms, the integrated filter, and the modular design. These innovations provide a significant improvement over the original patent, enhancing fluid flow reliability, reducing contamination risk, and minimizing maintenance needs.

Alternative embodiments of the inventive concept could include different wiping extension geometries, varying filter materials and configurations, and diverse valve body designs. Additionally, the self-cleaning mechanism could be implemented using different vibration frequencies or amplitudes, and the modular design could be adapted for use in various medical applications.

The enhanced check valve system has significant commercial potential in the medical industry, particularly in the context of intravenous sets. The system's ability to improve fluid flow reliability, reduce contamination risk, and minimize maintenance needs makes it an attractive solution for hospitals, clinics, and other healthcare providers. The market for intravenous sets is substantial, and the inventive concept's innovative features position it for success in this market.
