Swab Encapsulation Using Web Pressure to Prevent Cross-Contamination

The patent employs disposable pouches that are individually sealed and discarded after single use. Each pouch is pre-filled with a specific sample volume through a controlled dispensing mechanism, eliminating the need for cleaning and preventing cross-contamination between samples. The disposable nature ensures that no sample contact with reusable machinery elements occurs, while the automated filling process maintains high packaging efficiency.

The patent segments the packaging system into individual disposable pouches, each capable of containing a unique sample. The bulk storage container feeds into an automated dispensing mechanism that portions samples into separate pouches, maintaining process simplicity while enabling unique sample encapsulation. Each pouch is independently sealed, preventing cross-contamination between different samples while allowing the system to handle multiple unique samples sequentially.

The patent utilizes disposable pouches that are sealed and discarded after single use, eliminating the need for sample contact with reusable machinery elements. The automated filling process maintains high efficiency by using a controlled dispensing mechanism that transfers samples into the disposable pouches without requiring machinery components to contact the sample fluid, thereby preventing equipment contamination and reducing personnel risk.

The patent employs flexible pouches made from appropriate materials that can contain liquid samples while being processed by automated filling equipment. These pouches are designed to be compatible with liquid samples, providing reliable containment through their flexible structure that can conform to the filling mechanism. The pouches are sealed to prevent leakage while allowing efficient automated handling, bridging the gap between lamination-style containment and liquid sample handling requirements.
