Abstract: Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.

Abstract: A safety needle assembly includes a housing defining a cavity and having a button, a hub positioned in the cavity, and a needle connected with a distal face of the hub to extend out of the housing. The assembly includes a shield positioned in the cavity having a retracted mode in which the shield is retracted into the housing to expose the needle, and a securement mode in which the shield is extended over a distal end of the needle to cover the needle. A spring connects between the hub and the shield and is configured to transition the shield from the retracted mode to the securement mode. The assembly includes a lock-in mechanism configured to releasably maintain the shield in the retracted mode, and a lock-out mechanism configured to securely maintain the shield in the securement mode.

Abstract: Disclosed are systems that include a syringe having a barrel configured to hold a fluid and a plunger configured to draw the fluid into the barrel when the plunger is pulled backward through the barrel. The syringe is configured to inhibit forward movement of the plunger. For example, the systems can include mating pockets configured to engage barbs to inhibit forward movement of the plunger.

Abstract: A fluid sample optimization device for optimizing a fluid sample includes an inlet, an outlet, a sample path connected between the inlet and the outlet, and a contaminant containment reservoir connected between the inlet and the outlet. The contaminant containment reservoir includes an air permeable fluid resistor proximate the outlet, and is arranged to receive, when a pressure differential is applied between the inlet and the outlet, a first portion of the fluid sample to displace air therein through the air permeable fluid resistor and the outlet, such that upon receipt of the first portion of the fluid sample and containment of the contaminants in the contaminant containment reservoir, subsequent portions of the fluid sample can be conveyed by the sample path from the inlet to the outlet when subsequent pressure differentials are applied between the inlet and the outlet.

Abstract: A bodily fluid collection system for collecting a bodily fluid from a patient, and a bodily fluid transfer system for transferring collected bodily fluid to a second collection device. A collection adapter has a connection port configured to securely connect with a hub of a syringe, and a collection interface opposite the connection port creates a fluid conduit to the barrel via the connection port and an inlet of the hub. A proximal adapter is connected to a proximal end of the fluid channel from the patient, and configured to removably interact with the collection interface of the collection adapter to connect the proximal end of the fluid channel to the barrel via the fluid conduit and inlet to the barrel to allow conveyance into the barrel of the at least some of the sampling portion of the sample of bodily fluid. The proximal adapter can be removed to allow access to any bodily fluid collected by the syringe.
