Puritan Awarded U.S. Patent for PurFlock® Ultra Flocked Swab Collection Device

Puritan Medical Products, North America's largest manufacturer of single-use medical products, announced today that it has received a new United States patent for its high-performance PurFlock® Ultra swab, marking the second collection device patent the company has been awarded for flocked swabs since December.

"This second collection device patent for our PurFlock® Ultra collection device swab solidifies Puritan's worldwide reputation as a specialty swab manufacturer," said Puritan EVP of Sales Timothy Templet. "Puritan has once again proven its ability to manufacture high-performing products for use as specimen collection devices."

Puritan's latest flocked swab application (No. 12/849,250) from the United States Patent and Trademark Office (USPTO) is for both inventing the PurFlock® Ultra swab as well as for its unique manufacturing rocess.

The U.S. patent Puritan received for the HydraFlock® swab in December (No. 8,334,134) was also for inventing the product itself as well as for the unique manufacturing method involved.

Puritan's swabs produce superior sample collection, rapid elution, and increased test sensitivity by combining a unique microstructure with innovative fibers. Both the PurFlock® Ultra and HydraFlock® swabs are used in viral and bacterial transport systems and have been validated around the world with automated and manual laboratory practices.

Puritan was previously awarded a Canadian patent (No. 2,744,282) for the HydraFlock® swab as a product and for the manufacturing process in September. Patents for both the HydraFlock® swab and PurFlock® Ultra are also pending in other countries throughout the world.

Puritan Medical Products has expanded rapidly over the last few years as a direct result of the company's effort to meet the evolving needs of the healthcare, forensic, critical environment, food safety, and drug manufacturing industries.

Puritan now manufactures more than 35 types of swabs including the PurFlock® Ultra and HydraFlock® swabs, both manufactured in Guilford, Maine by American workers.
