Sample collection device for stool analysis
The granted patent US12004726B2 describes a novel collection device designed for the metered sampling of stool. The device features a body with a sample collection chamber that is sealed at the distal end by a penetrable seal and at the proximal end by a septum with an aperture. A flexible sampling rod, which fits through the septum and seals the aperture, is equipped with an asymmetrical beveled tip to minimize collisions with pipette tips or needles during sampling. The rod also includes metering ridges to retain a precise amount of stool, specifically 20 milligrams, within a chamber that can hold between 1 to 5 milliliters of sample. Additionally, the device can contain a solution for preserving the stool sample, with specific formulations including Tris buffer and other stabilizing agents.
Further claims of the patent detail various features of the device, such as the materials used for the body and seals, which may include polypropylene and foil layers, and the ability of the penetrable seal to withstand internal pressure. The device is designed for secure closure with a cap that engages the body, and it can be packaged for mailing, ensuring safe transport of the stool sample. The patent also outlines a system that includes the collection device and an implement for liquid withdrawal, enhancing the usability and functionality of the stool sampling process. Overall, this invention aims to improve the efficiency and reliability of stool sample collection and preservation for diagnostic purposes.
