a disinfecting material that is approved for usage inside the body; wherein penetration of a second connector through the at least one barrier causes or allows flow of said disinfecting material into the second connector in an amount and surface coverage sufficient disinfects a flow path between the second connector and the tube. ## Claims ### Claim 1 A dialysis device comprising: a disinfecting connector comprising a disinfecting chamber filled with a disinfecting material approved for usage inside a patient body, and positioned within an internal lumen of the disinfecting connector, wherein the disinfecting chamber includes: a proximal barrier positioned at one end of the disinfecting chamber; and a distal barrier positioned at an opposing end of the disinfecting chamber; wherein the dialysis device, which is configured for use with a second connector having an inner lumen, further comprises: an actuator configured to push, when activated, the disinfecting connector against the second connector so that an end of the second connector opens said distal barrier and said proximal barrier to create a flow path between the inner lumen of said second connector and the internal lumen of said disinfecting connector for releasing disinfecting material from the disinfecting chamber into the flow path. ### Claim 2 (depends on 1) The dialysis device of claim 1, wherein the distal barrier and the proximal barrier are sized and shaped to be opened in response to an axial force applied by a tip of the second connector. ### Claim 3 (depends on 1) The dialysis device of claim 1, wherein the proximal barrier and the distal barrier comprise any one of the following: a foil barrier and a pressure seal barrier. ### Claim 4 (depends on 1) The dialysis device of claim 1, wherein the disinfecting chamber comprises a compressible chamber. ### Claim 5 (depends on 4) The dialysis device of claim 4, wherein the compressible chamber comprises a sponge having a sponge volume and saturated at least partly with the disinfecting material, wherein the sponge volume is compressible by at least 30%. ### Claim 6 (depends on 5) The dialysis device of claim 5, wherein the sponge comprises a central channel aligned with a path of travel of the second connector, wherein penetration of the second connector through the central channel compresses the sponge to release the disinfecting material from the sponge into the inner lumen of the second connector. ### Claim 7 (depends on 1) The dialysis device of claim 1, wherein the disinfecting material disinfects the inner lumen of the second connector. ### Claim 8 (depends on 1) The dialysis device of claim 1, wherein the disinfecting material disinfects an external surface of the second connector.
