Abstract: A sample collection system includes a housing comprising a first part and a second part, the first and second parts being movable relative to one another; porous sample collection media disposed along an airflow path in the first part; and an assay disposed on the second part and constructed to receive a sample captured by the porous sample collection media. The first and second parts may be slidably movable relative to one another. The first and second parts may be rotatably movable relative to one another. Moving the first and second parts relative to one another aligns the porous sample collection media with at least a portion of the assay. The assay may be a lateral flow assay or a vertical flow assay. The media is constructed to collect a sample from exhalation airflow. A collected sample may be eluted from the media onto the assay using a liquid.

Abstract: The composition includes an antimicrobial monomer represented by formula CH2═C(R1)—C(O)—O-Q-N+(R)2CnH2n+1(X—), a non-fluorinated crosslinking monomer having at least two acrylate groups, methacrylate groups, or a combination thereof, a polar monomer having at least one of acrylic acid, methacrylic acid, or a carboxylate salt thereof, and a nonpolar monomer represented by formula CH2═C(R1)—C(O)—O—R2. The antimicrobial monomer, the non-fluorinated crosslinking monomer, the polar monomer, and the nonpolar monomer together account for greater than 95 percent by weight, based on the total weight of the composition. The article includes a film having a plurality of pendent groups represented by formula —C(O)—O-Q-N+(R)2CnH2n+1(X—) covalently bonded in a crosslinked non-fluorinated acrylic network. A method of making an article is also described.

CPC classification number: A61B5/097 , A61B2010/0087
Abstract: A sample collection device includes a housing including an exhalation portion and a coupling portion. The coupling portion can be coupled with/to a sample collection tube. An airflow path extends through the housing. The device further includes porous sample collection media partially disposed between within the housing and arranged to occlude the airflow path. The porous sample collection includes nonwoven material and may include polylactic acid, polypropylene, or a combination thereof. The housing can be a single piece, part, or component, or can be multiple pieces, parts, components, or portions. In an embodiment of a two-piece housing, the first part includes an exhalation piece (e.g., a mouthpiece or nosepiece) and the second part includes a coupling end constructed for coupling with a sample collection tube. A method of obtaining a sample using the sample collection device includes breathing into the exhalation piece or portion to collect a sample on the porous sample collection media; coupling the second part or portion with a sample collection tube; and transferring the collected sample on the porous sample collection media into the sample collection tube.

Abstract: A sample collection device including a housing extending from a mouthpiece portion to an air outlet portion. The housing defines an airflow channel from the mouthpiece portion to the air outlet portion. The mouthpiece portion is configured to receive an h exhalation airflow. A porous sample collection media is disposed within the housing and along the airflow channel. A fluid inlet port defines an aperture through the housing and is adjacent to the porous sample collection media. The fluid inlet port is configured to direct id onto the porous sample collection media. A metered fluid dose element is attached to the fluid inlet port. The metered fluid dose element is configured to dispense a metered volume of fluid into the fluid inlet port.
