Abstract: In certain aspects, a method includes determining that one or more alarm criteria of a first alarm condition of a dialysis machine is satisfied, and in response to determining that the one or more alarm criteria of the first alarm condition is satisfied, activating an alarm corresponding to the first alarm condition and activating a peripheral device.

Abstract: This disclosure relates to medical fluid delivery sets and related systems and methods. In some aspects of the invention, a medical fluid delivery set includes a syringe connected to a series of interconnected fluid lines. The syringe includes a medical fluid containment cylinder and a plunger assembly that can be axially moved relative to the medical fluid containment cylinder. The plunger assembly includes an inner plunger shaft including a seal that is slidably disposed within the medical fluid containment cylinder and an outer plunger shaft that at least partially surrounds the inner plunger shaft to form a space between an outer surface of the inner plunger shaft and an inner surface of the outer plunger shaft that is sized to receive a wall of the medical fluid containment cylinder therein.

Abstract: A dosimeter is provided on or adjacent to a circuit board deployed in a radiation environment. The dosimeter may be read or output a value or values indicating radiation dosage over a period of time. The radiation dosage associated with the circuit board may be used for determining disposition of the circuit board, such as whether to reuse the circuit board as a spare part or otherwise dispose of the circuit board.
