Non-vented vial drug delivery
First Claim
1. A method comprising:
- causing a gas to flow through a fluid line of a dialysis system until the gas enters a drug vial connected to a vial adapter assembly causing a pressure within the drug vial to increase; and
clamping the fluid line after increasing the drug vial pressure,wherein the fluid line comprises a first end connected to the vial adapter assembly 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 to be activated by depression so that deformation of the deformable portion causes gas to be forced from the gas chamber to the vial adapter assembly 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.
