Disclosed herein are methods that include contacting a skin surface with a first liquid composition; and then contacting in the skin surface with a cationic coated article loaded with a second liquid composition, while at least some portion of the first liquid composition remains on the skin surface, wherein one or both of the first liquid composition or the second liquid composition includes acrylate copolymer particles dispersed therein, the acrylate copolymer particles including the reaction product of a reaction mixture, the reaction mixture including monomers, the monomers including from about 5 wt % to about 50 wt % of at least one high Tg monomer where the wt % of the high Tg monomer is with respect to the total weight of the monomers in the reaction mixture; and from about 20 wt % to about 80 wt % of at least one low Tg monomer where the wt % of the low Tg monomer is with respect to the total weight of the monomers in the reaction mixture, wherein the particles have a number average diameter of at least about 100 nm and wherein at least one and only one of the first or the second composition comprises greater than or equal to 60 wt % of at least one alcohol.

An apparatus for sanitizing is provided. The apparatus includes a housing having a reservoir for retaining sanitizing fluid. The apparatus also includes a holder disposed beneath the housing. The apparatus further includes an applicator pad received by the holder and adapted to be in selective fluid communication with the reservoir. The applicator pad includes a dome-shaped portion having a substantially hemi-spherical shape configured to extend into an interior region of a bell of a stethoscope head when the bell is placed over the dome-shaped portion.

A sanitary method and system of providing touch interface experiences to users of public devices are disclosed. In one aspect, the system and method are configured to deploy a clean, protective barrier across a touchscreen for each user of the public device. The barrier includes a transparent membrane that permits the user to provide touch-based inputs to the touchscreen through the barrier. In cases where the touch interface is generated by a projector, the system and method are configured to deploy a membrane that serves as a disposable screen for the projected interface. Once each user completes their session, the system automatically replaces the used membrane with a fresh membrane, ensuring subsequent users are not exposed to contaminants or residue from previous user sessions.

Devices and methods for sterilizing the outer and inner surfaces of a working end-site of a medical device such as a catheter hub, luer connector, luer component, needleless access site, and/or access port are discussed. The sterilizing device can include a housing, a sterilizing element including an antipathogenic agent configured for sterilizing the working end-site of a medical device, and a cap hingedly coupled to the housing and configured to hermetically seal the sterilizing element within the housing. One or more features on the cap and housing serve to hermetically seal the cap to the housing prior to use.
