摘要： The present invention provides a blood parameter sensing system that may include a sensor, a blood access system, a flow controller and a monitor system. The blood access system may include a blood draw member having an internal configuration adapted to avoid clotting without the use of anticoagulants and under a range of flow profiles, including small volume blood draws. The flow controller may be configured to adapt to a range of access devices by using feedback from the sensor and monitor to customize flow profiles. The monitor system is configured to reduce parameter measurement error by modeling sensitivity change during system startup or reconnect.

摘要： The present disclosure provides a sensor system that includes a blood access device, a flow controller, and an analyte sensor. The system is configured to flush or draw a volume of fluid through the blood access device at least once; determine a signal-time history corresponding to signals received from the sensor; determine a duration of a portion of the signal-time history; determine whether the duration is greater than a predetermined threshold value; and detect the occlusion in the blood access device when the duration is greater than the predetermined threshold value.

摘要： Disclosed herein are systems and methods for analyzing failed bodily fluid sampling. The systems and methods include providing a system having a sampling line and an access device, the access device having an inner space, wherein the sampling line is positioned in the inner space; performing a sampling event; obtaining one or more status values of the sampling event; comparing the one or more status values with at least one predetermined value corresponding to a failed sampling event; and determining whether the sampling event failed based on the comparing step. In the event of sampling failure, the systems and methods provide flushing the sampling line or a portion of the inner space of the access device via the flow controller; detecting pressure; and determining one or more possible root causes for the failure of the sampling event based on the detected pressure.

摘要： The present disclosure provides a sensor system that includes a fluid supply, one or more supply lines, a monitor, communication lines, a sensor, a catheter and a connector assembly. The connector assembly includes a housing and a tube extending out of a distal end of the housing wherein the tube is compressed against a luer connector of the catheter to form a seal between the catheter and connector assembly.
