Abstract: An apheresis system at least partially defines a chamber and includes centrifuge that is movable between lock and unlock states. The centrifuge includes a base, cover, lock assembly, and latch assembly. The cover engages the base and defines slots. The lock assembly is coupled to the base and rotates between latched and unlatched states. The lock assembly includes tabs and a protrusion. The tabs are in the slots of the cover. The protrusion at least partially defines a receptacle. The latch assembly is coupled to the base and includes a lever and engagement component attached thereto. In the latched state, the protrusion engages the engagement component to reduce or prevent rotation of the lock assembly. In the unlatched state, the lock assembly can rotate. In the lock state, the tabs are at least partially within the slots. In the unlock state, the cover is movable with respect to the base.

Abstract: Methods and systems configured to measure content of a target substance in a fluid sample using a refractometer including a light source and a light sensor. A method includes: calibrating the refractometer by identifying a calibration pixel pattern of first pixels of the light sensor illuminated by light from the light source that has reflected off a sensing surface of a container including a reference fluid having a known reference density; identifying a blood pixel pattern of second pixels of the light sensor illuminated by light from the light source that has reflected off the sensing surface when the fluid sample is present in the container; identifying a pixel shift distance along the light sensor from the calibration pixel pattern to the fluid pixel pattern; and determining the content of the target substance in the fluid sample based on the pixel shift distance.

Abstract: A method includes detecting a condition including one or more of a change in flow of a fluid and a change in a composition of the fluid, issuing an alarm in response to the condition detected, lowering a flow rate; and attempting to restart process and increase the flow rate. The change in flow may include a change in pressure. The change in flow may be associated with a collapsed vein. The change in flow of the fluid may include detecting that the flow rate has fallen below a threshold. The change in the composition may be associated with a color. Thee change in the composition may include using a color sensor to detect one or more of a red, a green, and a blue reflection or transmission to detect red blood cells.

Abstract: A method includes: detecting an alarm event associated with an apheresis system; retrieving a graphical presentation output based on the alarm event detected; and rendering the graphical presentation output to a graphical user interface of the apheresis system. In the method, the alarm event can be related to one or more factors, such as: a temperature; a pressure; a flow rate; a color of fluid; and an excessive amount of received plasma. The alarm event can be detected when one of the factors crosses a threshold.

Abstract: A method for in-line sampling for a medical device includes prompting an operator of a medical device to establish a fluid communication between a fluid component collection set as received by the medical device and a sample system for sample collection, where the medical device prohibits removal of the fluid component collection set or a component thereof from fluid communication with the medical device until sample collection using the sample system is complete and the establishing of fluid communication between the fluid component collection set includes prompting the medical device to interpret a code disposed on an exterior-facing surface of the sample tube.
