Colorado Patent of the Month – July 2021

Straws, or anything of similar build, can carry and transfer microorganisms. A drinking straw is open to the environment and yet the user also regularly puts it in their mouth in order to drink. The environment of a straw makes it very easy to transfer microorganisms and pathogens to the user. Wilmarc Holdings, LLC. has designed an antimicrobial straw to reduce the spread of pathogens and increase the hygiene level.

Their structure applies to any straw-like structure – for instance, the tubing used to administer oxygen or drugs to patients. They designed a polymeric tubular conduit with two layers – an outer and inner tubular layer. The structure then also has an antimicrobial agent along the outer layer, sufficient enough to kill microorganisms and prevent them from growing or spreading. This creates a sufficiently hygienic straw or polymeric tubing system, preventing or reducing the spread of microorganism through everyday products.
