AI Technical Summary

Technical Problem

Existing endoscope valves with precision-fit valve stems and valve wells suffer from leakage issues due to manufacturing precision requirements, leading to inconsistent performance and high costs, especially in single-use valves.

Method used

The development of a valve stem integrally formed with seals from a single material, such as a thermoplastic elastomer, allowing for less precise manufacturing techniques and greater clearance within the valve well, reducing leakage and improving operational reliability.

Benefits of technology

The solution provides improved sealing performance and reduced manufacturing complexity, addressing leakage issues while maintaining functional integrity and lowering production costs for single-use valves.

Abstract

Devices, systems, and methods for a valve for a medical device. The valve may include a valve stem. The elongated body of the valve stem may include a first opening and a second opening fluidly coupled to each other via a lumen. The valve stem may include a first seal and a second seal extending circumferentially around the elongated body. The elongated body, the first seal, and the second seal may be formed from a single material. The single material may be a thermoplastic elastomer or other suitable material. The valve stem may include a recess adjacent the seal of the valve stem to facilitate bending or deflection of the seal as the valve stem translates within the valve well.
