Abstract: The disclosed packaging containers may include a body including a sidewall and at least one top flap for at least partially covering an opening of the body when assembled and perforations in the sidewall of the body. The perforations may include a lower perforation having a first end portion and a second end portion; a first side perforation extending upward toward the top flap from the first end portion of the lower perforation; and a second side perforation extending upward from the second end portion of the lower perforation, wherein the first side perforation and the second side perforation converge toward each other as they extend upward from the lower perforation. Various other packaging containers, systems, and methods are also disclosed.

Abstract: The disclosed packaging bags may include a flexible front sidewall and a flexible rear sidewall with at least a first closed edge, second closed edge, and third closed edge coupling the front sidewall to the rear sidewall. A perforation may be formed through the flexible front sidewall and the flexible rear sidewall along the first closed edge. The perforation may extend in a first segment from the first closed edge toward a central region of the packaging bag, in a second segment in a direction along the first closed edge, and in a third segment back to the first closed edge. The second segment may include at least one elongated ventilation slit. Various other related packaging bags and methods are also disclosed.

Abstract: A peritoneal dialysis (PD) fluid line set includes a fluid line configured to carry spent dialysate to a drain receptacle and a chemical testing device disposed along the fluid line. The chemical testing device is configured to detect a presence of a substance in the spent dialysate as the spent dialysate flows past the chemical testing device, and the chemical testing device is configured to provide a visual indicator of the presence of the substance in the spent dialysate.

Abstract: The disclosed arterial chambers for hemodialysis may include a cap with a blood inlet port for conveying an intended patient's blood into the arterial chamber, an auxiliary port configured to provide fluid access to the arterial chamber, and a needleless access port configured to couple to a needleless syringe. The needleless access port may be configured for administering a substance to an interior of the arterial chamber from the needleless syringe and/or for withdrawing blood from the interior of the arterial chamber into the needleless syringe. Various tubing sets, hemodialysis systems, and other components, systems, and methods are also disclosed.

Abstract: The disclosed flexible medical containers may include a substantially transparent bag including a cavity sized and configured to contain a medical substance, at least one port in fluid communication with the cavity, and at least one hanger hole sized and shaped for suspending the flexible medical container from a hanger. The hanger hole may be at least partially surrounded by a colored material to provide visible contrast between the colored material and the hanger hole. In some disclosed examples, the flexible medical containers may include one or more digit holes adjacent to the hanger hole to facilitate lifting and holding the flexible medical containers. Various other flexible medical containers, systems, and methods are also disclosed.
