  • Publication number: 20190351212
    Abstract: A cleaning device for disinfecting a Luer access device includes a housing and a cleaning material. The housing has an opening and elastomeric sidewalls defining an inner cavity. The elastomeric sidewalls are configured to deform and conform to respective surface features of the Luer access device. The cleaning material is positioned within the inner cavity and carries a disinfectant. The cleaning device is configured to removably engage the Luer access device, and the cleaning material is configured to contact at least a portion of the Luer access device when the cleaning device is engaged with the Luer access device.
