摘要： In some embodiments, an external bladder management system that is configured to reside within a urine collection receptacle (e.g., a toilet) includes a body that houses a fluid testing chamber. The fluid testing chamber is fluidically coupled to a fluid inlet and a fluid outlet. The system further includes a fluid capturing funnel fluidically coupled to and extending from the body and configured to couple the body to the urine collection receptacle. The system further includes an optical sensor disposed within the body and including (1) an emitter configured to convey light across the fluid testing chamber, and (2) an optical detector capable of measuring an intensity of the light as the light exits the fluid testing chamber. The fluid inlet, fluid testing chamber, and fluid outlet are collectively configured to encourage a laminar flow profile of the fluid as it flows through the fluid testing chamber.

摘要： Various systems and methods for detecting air in a chamber of an infusion system are disclosed. In one embodiment, a determination is made that air is contained in the chamber on the basis of a change in the average force exerted against the plunger utilizing a derivative spike for event detection and a systematic reduction in the average force to confirm the nature of the change. In another embodiment, a determination is made that the chamber contains air when a difference between the current force profile and a baseline force profile crosses a threshold. In an additional embodiment, a force profile is classified as being an air force profile or a liquid force profile based on extracted features of the force profile.

摘要： A system is provided for separating a plasma-containing fluid into separated plasma and a concentrated fluid. The system cooperates with a fluid flow circuit including a fluid separation chamber and a plasma outlet line associated therewith for removing separated plasma from the fluid separation chamber. The system includes an optical sensor assembly to monitor the contents of the plasma outlet line and produce an output indicative of the concentration of free plasma hemoglobin in the plasma outlet line. A controller of the system calculates the amount of free plasma hemoglobin in at least a portion of the concentrated fluid based at least in part on the output of the optical sensor assembly. The controller may periodically calibrate the optical sensor assembly by determining an instrument-specific correlation between optic output and free hemoglobin concentration and comparing it to experimentally determined data to ensure continued reliability of the optical sensor assembly.

摘要： An optical monitoring system is provided for use with a blood processing system. The system includes a light source configured to illuminate a disposable flow circuit received in a centrifuge and a light detector configured to receive an image of the disposable flow circuit. A controller combines two or more of the images received by the light detector to generate a two-dimensional output. The output is used to control the separation of blood within the disposable flow circuit. The monitoring system may also be used to verify that the disposable flow circuit is suitable for use with the centrifuge or that the disposable flow circuit is properly aligned within the centrifuge. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge.

摘要： A blood component separation device includes a centrifuge bowl for separating a blood component from blood, a plasma bag for storing a plasma component, a platelet intermediate bag for storing high-concentration platelet liquid having high-concentration of platelets, and a temporary storage bag (also used as a buffy coat bag) for storing low-concentration platelet liquid having low-concentration of platelets. The blood component separation device performs control, from the second cycle onward, to mix the low-concentration platelet liquid stored in the temporary storage bag in the immediately preceding cycle with whole blood to supply the mixed liquid to the centrifuge bowl. An amount of high-concentration platelet liquid to be collected in the platelet intermediate bag in the first cycle is set to be smallest among all cycles, and an amount of high-concentration platelet liquid to be collected in a last cycle is set to be greatest among all the cycles.
