A device for automatically disinfecting a portion of a medical implement. The device includes a reservoir chamber having a top external opening, a medical implement protruded through a bottom part of the reservoir chamber with the portion to be disinfected exposed inside the reservoir chamber and below the top external opening, two disinfecting pads, and a resilient device. Each disinfecting pad is connected to the reservoir chamber through a mounting member, which permits displacement of the disinfecting pads relative to the reservoir chamber in substantially opposite directions thereby creating a gap between each pad and the portion to be disinfected. The resilient device biases the disinfecting pads such that when the disinfecting pads are displaced from a rest position, wherein they are contacting the portion to be disinfected, to an engaged position, the disinfecting pads are urged to return toward the portion to be disinfected to contact and disinfect the portion.
