Each disinfecting chamber houses a disinfecting member that is exposed through the medial opening to come into communication with a medical implement when the disinfecting chambers are closed. The device further includes a resilient member connected to the two disinfecting chambers, which biases the disinfecting chambers together to a closed position and permits displacement of the disinfecting chambers to an open position, such that the medial opening of one disinfecting chamber communicates with the medial opening of the other disinfecting chamber and the bottom opening of one chamber communicates with the bottom opening of the other chamber when in the closed position. ## Claims ### Claim 1 A device for disinfecting a portion of a medical implement, wherein the portion to be disinfected comprises an injection membrane and female luer threads, the device comprising: a resilient member, and two disinfecting chambers connected to each other through the resilient member so as to form a continuous periphery defining a bottom opening having a predetermined size, wherein each disinfecting chamber comprises a wall and a medial opening, wherein the medial opening and the bottom opening are in communication with each other, and wherein one disinfecting chamber is opposed to the other, and wherein each disinfecting chamber houses a sealing member parallel to the bottom opening and a disinfecting member that is disposed on the sealing member, wherein each disinfecting member is exposed through its respective medial opening to come into communication with a medical implement when the two disinfecting chambers are closed, wherein the sealing member comprises an elevated central rim; and wherein the resilient member biases the two disinfecting chambers together to a closed position and permits displacement of the two disinfecting chambers to an open position, wherein, in the closed position, the disinfecting members fully enclose the portion to be disinfected so that each disinfecting member is in a direct and prolonged contact with the injection membrane and the female luer threads of the medical implement, wherein, in the open position, the disinfecting members are not contacting the medical implement or each other, and wherein the medial opening of each disinfecting chamber and the bottom opening are substantially configured to receive and be biased against the medical implement. ### Claim 2 (depends on 1) The device according to claim 1, wherein the sealing member of each disinfecting chamber is configured to separate the medial and bottom openings. ### Claim 3 (depends on 1) The device according to claim 1, wherein each disinfecting member is disposed over the entire surface of each disinfecting chamber. ### Claim 4 (depends on 1) The device according to claim 1, wherein the two disinfecting chambers further comprise a hollow internal space disposed between the disinfecting members and the medial openings, wherein the shape of the hollow internal space substantially matches the shape of the portion of the medical implement. ### Claim 5 (depends on 1) The device according to claim 1, wherein the two disinfecting chambers displace relative to each other so as to create a cavity between the two disinfecting chambers. ### Claim 6 (depends on 1) The device according to claim 1, wherein each disinfecting chamber further comprises a handle disposed on an external surface of the wall, and wherein the two disinfecting chambers displace by application of a force to the handles. ### Claim 7 (depends on 1) The device according to claim 1, wherein the two disinfecting chambers displace by application of a force directly to an external surface of each wall. ### Claim 8 (depends on 1) The device according to claim 1, wherein the disinfecting members directly contact each other in the closed position. ### Claim 9 (depends on 1) The device according to claim 1, wherein the disinfecting members are impregnated with a disinfecting agent. ### Claim 10 A system for disinfecting a portion of a medical implement, wherein the portion to be disinfected comprises an injection membrane and female luer threads, the device comprising: a resilient member, and two disinfecting chambers connected to each other through the resilient member so as to form a continuous periphery defining a bottom opening having a predetermined size, wherein each disinfecting chamber comprises a wall and a medial opening, wherein the medial opening and the bottom opening are in communication with each other, and wherein one disinfecting chamber is opposed to the other, and wherein each disinfecting chamber houses a sealing member parallel to the bottom opening and a disinfecting member that is disposed on the sealing member, wherein each disinfecting member is exposed through its respective medial opening to come into communication with a medical implement when the two disinfecting chambers are closed, wherein the sealing member comprises an elevated central rim; and wherein the resilient member biases the two disinfecting chambers together to a closed position and permits displacement of the two disinfecting chambers to an open position, a medical implement protruded through the bottom opening of with the portion to be disinfected exposed inside the two disinfecting chambers, wherein, in the open position, the disinfecting members are not contacting the medical implement or each other, wherein, in the closed position, the disinfecting members fully enclose the portion to be disinfected so that each disinfecting member is in a direct and prolonged contact with the injection membrane and the female luer threads of the medical implement. ### Claim 11 (depends on 10) The system according to claim 10, wherein the disinfecting member of each disinfecting chamber is impregnated with a disinfecting agent, and wherein when the disinfecting member is in contact with the portion to be disinfected, the disinfecting member releases the disinfecting agent onto the portion to be disinfected. ### Claim 12 (depends on 10) The system according to claim 10, wherein the resilient member is permanently affixed to the medical implement so as to form a single entity. ### Claim 13 (depends on 10) The system according to claim 10, wherein the resilient member and the medical implement are not permanently affixed. ### Claim 14 (depends on 10) The system according to claim 10, wherein a combined internal surface of the walls of the two disinfecting chambers in the closed position fully encircles the portion of the medical implement to be disinfected. ### Claim 15 (depends on 10) The system according to claim 10, wherein the portion to be disinfected in the open position is completely uncovered. ### Claim 16 (depends on 11) A method for disinfecting a portion of a medical implement, comprising: providing the system according to claim 11; displacing the two disinfecting chambers from the closed position to the open position to expose the portion of the medical implement; and attaching a source of fluid to the medical implement. ### Claim 17 (depends on 16) The method according to claim 16, further comprising: injecting the fluid into the medical implement; detaching the source of fluid from the medical implement; and displacing the two disinfecting chambers from the open position to the closed position to bring the disinfecting members back in contact with the portion to be disinfected.
