A capping device is configured to terminate a connector while disconnected from another connector in a fluid transportation system, e.g., for peritoneal dialysis. The connector comprises an exposed surface portion that is enclosed when the connector is connected to the other connector. The capping device comprises a body defining a chamber with an opening, a liquid-containing disinfectant in the chamber, a sealing element arranged in the opening to form a sealed cavity retaining the disinfectant, and a structure for engaging and guiding the connector towards the body such that a portion of the connector displaces the sealing element into the chamber. The sealed cavity is configured such that a displacement of the sealing element into the chamber actively presses the disinfectant out of the sealed cavity, for disinfecting at least part of the exposed surface portion. The capping device may be manufactured by introducing the liquid-containing disinfectant into the chamber through the opening, and by arranging the sealing element in the opening to form the sealed cavity.

1. A capping device configured to terminate a first connector while disconnected from a second connector a fluid transportation system, said first connector comprising an exposed surface portion, said exposed surface portion being enclosed when the first connector is connected to the second connector, said capping device comprising: a body defining a chamber with having an opening;a liquid-containing disinfectant in the chamber;a sealing element arranged in the opening to form a sealed cavity retaining the disinfectant; anda structure configured to engage and guide the first connector towards the body such that a portion of the first connector displaces the sealing element into the chamber,wherein a circumferential portion of the sealing element is in continuous contact with a cylindrical wall portion of the chamber during a displacement of the sealing element into the chamber, andthe sealed cavity is configured such that the displacement of the sealing element into the chamber causes a pressure inside the sealed cavity to increase, thereby actively pressing the disinfectant out of the sealed cavity and on to at least part of the exposed surface portion. 2. The capping device of claim 1, wherein the chamber comprises at least one deformation element arranged to deform the sealing element during at least part of said displacement, so as to define a fluid path for the disinfectant. 3. The capping device of claim 1, wherein at least One fluid channel is defined in said body, said at least one fluid channel being configured to direct the disinfectant onto said exposed surface portion. 4. The capping device of claim 1, wherein the sealing element comprises a circumferential portion in contact with a cylindrical wall portion of the chamber during said displacement, wherein the disinfectant is pressed to flow past said circumferential portion. 5. The capping device of claim 4, wherein at least the circumferential portion of the sealing element is resilient. 6. The capping device of claim 5, wherein the circumferential portion is made of resilient material. 7. The capping device of claim 4, wherein the cylindrical wall portion comprises at least one protrusion configured to cause a local deformation of the circumferential portion during at least part of said displacement. 8. The capping device of claim 7, wherein said at least one protrusion is elongate and extends in an axial direction of the cylindrical wall portion. 9. The capping device of claim 7, wherein said at least one protrusion is part of a protruding element that extends in a circumferential direction of the cylindrical wall portion while defining at least one gap along the extent of the cylindrical wall portion. 10. The capping device of claim 4, wherein the cylindrical wall portion comprises at least one elongate groove having first and second ends, wherein both of said first and second ends of the groove are uncovered during at least part of said displacement. 11. The capping device of claim 4, wherein the circumferential portion comprises a cylindrical lip element that abuts on the cylindrical wall portion during said displacement. 12. The capping device of claim 1, wherein the chamber has an increasing cross-section from said opening in the direction of said displacement, and wherein the sealed cavity is essentially filled with the disinfectant. 13. The capping device of claim 1, wherein the sealing element comprises an area configured to engage said portion of the first connector, said area being aligned with a geometric centre of the sealing element. 14. The capping device of claim 1, wherein the chamber is formed as a blind hole in said body, and wherein the sealing element is fitted into the blind hole. 15. The capping device of claim 14, wherein the sealing element is displaceable in the axial direction of the blind hole. 16. The capping device of claim 1, wherein said portion of the first connector comprises a valve arranged to seal a lumen in the first connector, wherein the sealing element comprises a projection configured to engage and open the valve as the first connector is guided towards the body. 17. The capping device of claim 1, wherein The disinfectant comprises at least one of: povidone iodine, iodine-containing antimicrobials, and betadine. 18. The capping device of claim 1, wherein the sealing element comprises at least one rigid protrusion configured to cause a local deformation of a wall portion of the chamber during at least a part of said displacement, so as to define a fluid path for the disinfectant.
