Described is a needle assembly storage device comprising an array of needle assembly storage compartments and a slider movably disposed on the array. Each of the needle assembly storage compartments includes an opening, rails disposed on opposing sides of the opening, and a latch hingedly connected to the needle assembly storage compartment. The latch has an open position and a closed position at least partially covering the opening. The slider includes an opening adapted to receive an injection device, arms adapted to engage the rails and a trailer. Movement of the slider relative to the array in a first direction causes the trailer to move the latch in the open position to the closed position.
