Non-vented vial drug delivery
First Claim
1. A fluid line set comprising:
- a vial adapter comprising;
a base;
a spike extending from a central region of the base; and
a sidewall extending from the base and substantially surrounding the spike, the base and the sidewall at least partially defining a cavity configured to receive a portion of a vial;
a fluid line having a first end connected to the vial adapter and a second end; and
a cap removably attached to the second end of the fluid line such that the cap seals the second end of the fluid line, the cap comprising;
a deformable portion at least partially defining a gas chamber, the deformable portion being a bistable diaphragm configured to be activated by depression so that deformation of the deformable portion from a first position having a convex shape moves the deformable portion to a second position having a concave shape and causes gas to be forced from the gas chamber to the vial adapter via the fluid line.

Abstract
This disclosure relates to fluid line sets and related methods. In certain aspects, the fluid line sets include a vial adapter connected to a first end of a fluid line, and a cap removably attached to a second end of the fluid line such that the cap seals the second end of the fluid line. The vial adapter includes a base, a spike extending from a central region of the base, and a sidewall extending from the base and substantially surrounding the spike. The base and the side wall at least partially define a cavity configured to receive a portion of a vial. The cap includes a deformable portion at least partially defining a gas chamber, and the cap is configured so that deformation of the deformable portion causes gas to be forced from the gas chamber to the vial adapter via the fluid line.

8. A dialysis system comprising:
-
a dialysis machine comprising; a blood pump; and a drug pump; a blood line set comprising a blood line that can be operably connected to the blood pump and a drip chamber in fluid communication with the blood line; a fluid line set comprising a fluid line including a first end connected to a vial adapter and a second end; and a cap removably attached to the second end of fluid line such that the cap seals the second end of the fluid line, the cap comprising; a deformable portion at least partially defining a gas chamber, the deformable portion being a bistable diaphragm configured so that it is activated by depression to cause deformation of the deformable portion from a first position having a convex shape moves the deformable portion to a second position having a concave shape and causes gas to be forced from the gas chamber to the vial adapter via the fluid line. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
