A peritoneal dialysis system comprises a cycler including an air pump; a heater housing including a heater and an expandable bladder in fluid communication with the air pump, wherein the heater housing is sized to receive a heater bag between a wall of the housing and the expandable bladder; a plurality of nesting containers configured for fluid communication with the air pump a disposable set operable with the cycler and including the heater bag and a plurality of fluid supply bags for placement within the plurality of nesting containers; and a control unit programmed to control the air pump and the heater.

A disposable cartridge for a drug delivery device includes a flexible bag to accommodate a liquid medicament and having an opening adjacent to a sidewall, a socket having a fluid channel in fluid communication with a cartridge fluid coupling, and a housing covering at least a portion of the flexible bag and having a receptacle to receive the socket with the flexible bag. The socket extends into the opening of the flexible bag. The flexible bag's sidewall is fixed between the socket and the receptacle.

A drug delivery system includes a single-use cassette driven by a reusable pump module. The cassette includes one or more drug delivery bags disposed in a pressure chamber. A pump pressurizes the pressure chamber through a pneumatic interface between the pump module and cassette to dispense the drug from the drug delivery bags into a valve block assembly and through an outlet port.

A peritoneal dialysis system includes a cycler having one or more air pump; a slotted housing including a plurality of slots each having a first side and a second side, wherein each respective slot of the plurality of slots includes a first expandable bladder fixed to the first side, and wherein each respective slot of the plurality of slots is configured to receive a fluid supply bag between the first expandable bladder and the second side, and a heater housing sized to hold a second expandable bladder, and wherein the heater housing is configured to receive a fluid heater bag adjacent to the second expandable bladder, wherein the one or more air pump is in fluid communication with the respective first expandable bladders and the second expandable bladder; and a disposable set operable with the cycler.

A patch-type drug injection pump according to an embodiment of the present disclosure includes: a housing including a lid and a contact surface; and components disposed in a mounting space between the lid and the contact surface. The components include: a drug reservoir in which a drug to be injected is stored; a pump assembly configured to be driven to transfer the drug in the drug reservoir toward an injection target; a circuit unit equipped with electronic components necessary for driving and controlling the pump; and an injection assembly equipped with an insertion tube to be inserted into the injection target. The injection assembly is disposed at a central region of the mounting space. Further, the drug reservoir, the pump assembly, and the circuit unit are disposed to surround the injection assembly.
