1. A peritoneal dialysis connector set comprising:
- a male connector includinga spike portion having a distal end and a proximal end,a spike located at the distal end,a seal apparatus located at the proximal end and fixed to the spike portion, the seal apparatus including an outer surface, anda first tube connection portion adjacent to the spike portion; and
a female connector includinga second tube connection portion having a tube section and a mouth section, the tube section having a tube end configured to receive a tube, the mouth section having a mouth end configured to receive the spike, the second tube connection portion defining a lumen extending longitudinally between the tube end and the mouth end, anda shroud including a radial wall and an axial wall, the radial wall extending from the mouth end in a radial direction and the axial wall including an inner surface and extending from the radial wall in an axial direction so as to protect the mouth end from human touch, the radial wall and the axial wall forming an enclosure sized (i) to seal to the seal apparatus of the male connector via the outer surface of the seal apparatus contacting the inner surface of the axial wall of the shroud and (ii) to enable the seal apparatus to remain safely away from the mouth end when the male connector and female connector are mated.

Abstract
Peritoneal dialysis connectors, connector sets, connector systems and methods are disclosed. In an embodiment, a connector includes, a body, a spike located at a first end of the body, a sealing ring sized to seal inside a female connector and located adjacent to the spike end, threads located adjacent to the sealing ring, and at least one barbed ring located adjacent to the threads at a second end of the body. The at least one barbed ring is configured to seal the second end of the body to a tube.

12. A peritoneal dialysis connector set comprising:
-
a male connector including a sealing portion and a spike connector including a spike, the sealing portion fixed to the spike connector and including an outer surface; and a female connector including a tube connection portion having a tube section and a mouth section, the tube section having a tube end configured to receive a tube, the mouth section having a mouth end configured to receive the spike connector, the tube connection portion defining a lumen extending longitudinally between the tube end and the mouth end, and a shroud including a radial wall and an axial wall, the radial wall extending from the mouth end in a radial direction and the axial wall including an inner surface and extending from the radial wall in an axial direction so as to protect the mouth end of the tube connection portion from human touch, the axial wall of the shroud sealing to the sealing portion of the male connector via the outer surface of the sealing portion contacting the inner surface of the axial wall of the shroud, the axial wall extending axially from the radial wall a distance sufficient to preclude the sealing portion of the male connector from contacting the mouth end of the tube connection portion of the female connector. - View Dependent Claims (13, 14, 15, 16)

17. A peritoneal dialysis connector comprising:
-
a body including a first end and a second end, the second end of the body having an outer diameter; a spike located at the first end of the body; a sealing ring located adjacent to the spike, the sealing ring sized to seal inside a female connector; threads located adjacent to the sealing ring; and first and second barbed rings located adjacent to the threads at the second end of the body, the first and second barbed rings spaced apart a distance at least as large as the outer diameter of the body and configured to seal the second end of the body to a tube having a thickness, and wherein (i) a length of the second end of the body extending from an edge of the second end to the threads is at least two times that of the outer diameter of the second end of the body, and (ii) the first and second barbed rings extend radially away from the body a distance that is less than or equal to the thickness of the tube. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A peritoneal dialysis connector set comprising:
-
a port connector including a tube connection portion having a tube section and a mouth section, and a port; and a spike connector including (i) a spike portion including a spike and (ii) a sealing portion located adjacent to the spike portion, the sealing portion fixed to the spike connector and including an outer surface, the sealing portion configured to snap-fit to the port of the port connector, wherein the tube connection portion defines a lumen extending longitudinally between a tube end of the tube section and a mouth end of the mouth section, the tube end configured to receive a tube and the mouth end configured to receive the spike portion, and wherein the port includes a radial wall and an axial wall, the radial wall extending from the mouth end in a radial direction and the axial wall including an inner surface and extending from the radial wall in an axial direction so as to protect the mouth end from human touch, the axial wall of the port sealing to the sealing portion of the spike connector via the outer surface of the sealing portion contacting the inner surface of the axial wall. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)
