Abstract
A safety cap cover for use with a medication pump and a method for using a pump are described, where the cap cover makes the pump is more difficult for a child to open. The cap cover according to the present invention is configured to reversibly attach to and enclose a pump cap of a medication pump. The cap cover is movable from a first state to a second state on the pump cap. In the first state, the safety cap cover rotates freely around the pump cap. In the second state, the cap cover contacts an exterior surface of the pump cap so that the user can apply torque on the pump cap through the cap cover to rotate the pump cap. Preferably, the safety cap cover is moved from the first state to the second state by applying a radially inward force on opposing sides of the cap cover.
