1. A drug delivery device, comprising:
- a peristaltic pump extending from a surface of the drug delivery device, the peristaltic pump comprising a frame and a plurality of rollers positioned about a circumference of the frame, the frame being rotatably secured to a rod that is fixed to a housing of the drug delivery device; and
a door having an inner surface and comprising a spring-loaded member exposed along the inner surface, the spring-loaded member defining a recess configured to receive a portion of the peristaltic pump when the door is closed, a first adjustable spring being connected to the spring-loaded member and being secured to the door,wherein, when a fluid line is positioned in the recess and the door is closed, the fluid line is compressed between the spring-loaded member and the peristaltic pump in a manner such that the fluid line is occluded in at least one location.

16. A dialysis system comprising:
-
a dialysis machine comprising a blood pump, a modular drug delivery device comprising at least one drug pump and a plurality of drug vial holders, and a housing to which the blood pump and the modular drug delivery device are secured; a blood line set comprising multiple blood lines and a vented chamber in fluid communication with the multiple blood lines, at least one of the blood lines being connected to the vented chamber, the blood line set being connected to the blood pump in a manner such that, when the blood line set is connected to a patient and the blood pump is operated, blood of the patient is passed through the blood line set; a drug line set comprising multiple drug lines, at least one of the drug lines of the drug line set being connected to the vented chamber of the blood line set, and the drug line set being connected to the at least one drug pump in a manner such that, when the drug line set is fluidly connected to one or more drug vials contained in the multiple drug vial holders and the at least one drug pump is operated, drug is delivered from the one or more drug vials to the vented chamber of the blood line set via the drug line set; and a control unit configured to operate the blood pump and the drug pump to simultaneously deliver drug and blood to the vented chamber via the at least one of the drug lines connected to the vented chamber and the at least one of the blood lines connected to the vented chamber, respectively.

17. A drug delivery device, comprising:
-
a plurality of pumps extending from a surface of the drug delivery device; and a door having an inner surface and comprising a plurality of spring-loaded members exposed along the inner surface, each of the spring-loaded members defining a recess configured to receive a portion of one of the pumps when the door is closed, wherein, when a fluid line is positioned in the recess and the door is closed, the fluid line is compressed between the spring-loaded member and the pump in a manner such that the fluid line is occluded in at least one location; a plurality of air bubble detectors, each of the air bubble detectors being arranged to substantially align with a fluid line when fluid lines are positioned within the recesses of the door and the door is closed such that the air bubble detectors can detect air within the fluid lines; and a plurality of drug vial holders positioned above the plurality of pumps, each of the drug vial holders being configured to retain at least one drug vial, wherein the drug delivery device is configured to operate the pumps in a manner such that, when fluid lines are positioned in the recesses of the door, the door is closed, and each of the fluid lines is in fluid communication with a drug vial retained by one of the drug vial holders, an air bubble is passed through a drug delivery line connected to each of the fluid lines between the delivery of drug from consecutive vials. - View Dependent Claims (18, 19, 20)
