Abstract

An antiseptic cap and packaging for use with a connector are provided. The antiseptic cap includes a material containing an antiseptic solution. Upon application of the cap to the connector, the material compresses thereby releasing the antiseptic solution. Packaging of the antiseptic cap typically includes a cap holder and a lid. A user could remove the cap from the cap holder before applying it to a connector. Alternatively, the cap holder may be used to apply the cap to the connector.
