A fluid control device includes an inlet configured to be placed in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. The fluid control device has sequestration portion that can be vented or evacuated. The fluid control device has a first state in which an initial volume of bodily fluid can flow from the inlet to the sequestration portion and a second state in which (1) the initial volume is sequestered in the sequestration portion, and (2) a subsequent volume of bodily fluid, being substantially free of contaminants, can flow through at least a portion of the fluid control device and into the fluid collection device. The fluid control device can transition automatically or in response to an actuation of a portion of the fluid control device after the sequestration portion receives the initial volume.

The present invention extends to a closed IV line draw system which may be used with a PIVC or another vascular access device to collect blood samples. The closed IV line draw system consists of various integrated components that allow the system to remain closed during the blood collection process. In this way, the closed IV line draw system simplifies the blood collection process and reduces the risk of contamination to the PIVC or other vascular access device.

An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.

A blood collection system can include a cannula for insertion into a catheter system that comprises a hub with an internal chamber, a distal port in fluid communication with the internal chamber and coupled with a catheter tube that can be preplaced in a blood vessel of a patient, and an access port in fluid communication with the internal chamber. The cannula can be inserted in the catheter tube and can include a distal opening that is positioned within the blood vessel of a patient and is in fluid communication with an interior of the blood vessel to permit blood to flow into a lumen of the cannula, and can include a proximal opening positioned within the internal chamber to permit blood to flow from the cannula into the internal chamber and through the access port of the hub.

An integrated intravenous catheter including a catheter adapter having a catheter and an inlet, the catheter configured to be inserted into a patient's vasculature, as well as a needle free connector. The needle free connector includes first port, a second port positioned opposite the first port, and a side port positioned between the first port and the second port. The needle free connector further includes a main cavity portion having a tapered sidewall and a distal taper portion, wherein the tapered sidewall gradually narrows in a direction of the distal taper portion. The integrated intravenous catheter also includes intermediate tubing extending between the inlet of the catheter adapter and the first port of the needle free connector, and extension tubing extending from the side port of the needle free connector.

A blood collection apparatus is provided with a blood collection assembly including a casing tube including a forward nose, a plurality of connectors and a rear flange having a flexible projection, a plunger slidably disposed in the casing tube and including a forward plug and an elongated arm having a plurality of cavities, a blood collection tubes, an adapter assemblies each including a tube body, a first tube extending out of one end and insert into a related connectors of the casing tube, a second tube extending out of the end to insert into one of the blood collection tubes, and a butterfly needle assembly mounted to the nose of the casing tube. A pulling of the plunger moves the plug rearward and pivots the projection to engage in one cavity of the elongated arm and an orifice of the each related connectors is not blocked by the plug so as to flow blood from the tube casing to one of the blood collection tube via one connector and one adapter assembly.

A system acquiring body fluid samples is provided. One embodiment comprises a housing with a sampling channel extending therethrough and defined by an inlet port and an outlet port, wherein the inlet port secures a needle that penetrates a patient; a diversion chamber body portion directly secured to the housing with at least one diversion chamber, wherein the diversion chamber is in fluid communication with the sampling channel, wherein an initial first portion of the body fluid received from the needle is transferred through the sampling channel inlet port and into the diversion chamber, and wherein a subsequent second portion of the body fluid received from the needle is communicated through the sampling channel to the outlet port for collection into a collection device while the initially received first portion of the body fluid is retained in the diversion chamber.
