Abstract: Processes and systems for lessening human spread of coronaviruses can include use of a disinfectants and/or rinses that utilize contact times of up to 2 minutes or less than 2 minutes and also more than 20 seconds. Some embodiments can include gargling a rinse having at least one disinfectant as an active ingredient for up to 2 minutes or for a time period of less than 2 minutes. Other embodiments can include performing a naso-rinse for up to 2 minutes or a time period of less than 2 minutes and also more than 20 seconds with rinse fluid having at least one disinfectant.

Abstract: The device can include a first member connected to a second member via junctions. The members can be statically or pivotally connected at the junctions via arms extending from cross-beams of the members. The junctions can be configured to provide a biasing force. Methods of using the device may include collapsing the device and inserting it through an incision, allowing the biasing force to cause continuous traction and counter-traction adjacent to a leading dissection edge so that retraction of the skin from the tissue can be facilitated during a surgical procedure.
