A shieldable needle device including a drive member is disclosed. The drive member is extendable between a biased position and an extended position for moving a tip guard from an first position to a second position in which the tip guard shields a distal end of the needle cannula. The shieldable needle device includes a pair of wings extending laterally from opposing sides of the hub that are movable between a laterally extending position and a dorsal position. With the wings in the dorsal position, the wings retain the drive member in the biased position thereby maintaining the tip guard in the first position. Movement of the wings from the dorsal position to the laterally extending position releases retainment of the drive member. A second drive member may be included.

An integrated peripheral intravenous (IV) catheter configured for blood draw both at the time of catheter placement and during catheter indwell. The peripheral IV catheter includes a catheter adapter having a catheter configured to be inserted into a patient's vasculature and a side inlet defining a fluid pathway into and out of the catheter. The peripheral IV catheter also includes a side port member having a main branch, the main branch including a distal end configured to couple the side port member to the side inlet of the catheter adapter and a connector portion accessible via a proximal end of the main branch. Additionally, the peripheral IV catheter includes a blood collection adapter removably and directly coupled to the connector portion of the side port member at the proximal end of the main branch. Furthermore, side pore member of the peripheral IV catheter may include a side branch.

A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.

The present disclosure is a blood collection assembly that has a needle assembly fixedly coupled to a finger-activated actuator and tubing and the needle assembly has a needle. Further, the blood collection assembly has a hub that houses the needle assembly and the hub has a channel in a top surface of the hub. Additionally, the channel slidably engages the finger-activated actuator such that when the finger-activated actuator is moved from a distal end of the hub to a proximal end of the hub the needle retracts within the hub.

Peripheral intravenous catheter assemblies with capabilities for both blood sampling and catheterization can have a blood collection holder with a needle hub attached to a catheter hub. The combination catheter assembly and blood sampling holder can be called a catheter and holder assembly. Blood sampling can be done directly through the needle and the blood collection holder after cannulation. After blood sampling, the blood collection holder and the needle can be removed, leaving the catheter hub with the patient for IV infusion. The catheter hub can be a straight catheter hub or can include a side fluid port for use in as an integrated IVC.

A blood sequestration device configured to isolate an initial, potentially contaminated portion of blood from the flow of blood of a patient, prior to directing the flow of blood to an outlet port where the blood can be accessed. The blood sequestration device including a body member having an interior wall defining a fluid conduit having a distal portion, a first proximal portion, and a second proximal portion, wherein the first proximal portion defines a sequestration chamber configured to isolate an initial portion of blood of a flow of blood, a vent path configured to enable the escape of gas initially trapped within the sequestration chamber.

A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.

An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

A blood sequestration device includes an inlet path, an outlet path, a sequestration chamber, and a sampling channel. The sequestration chamber is connected with the inlet path by a junction and is configured to receive a first portion of blood through the inlet path. The sequestration chamber has a vent that allows air to be displaced by the first portion of blood, the junction being configured to inhibit a return to the inlet path of any of the first portion of blood received by the sequestration chamber. The sampling channel is connected between the inlet path and the outlet path, and configured to convey subsequent amounts of blood between the inlet path and the outlet path after the first amount of blood is received by the sequestration chamber.

In certain instances, an access system includes a connector to couple with a closed intravenous catheter system that includes a valve and a catheter tube. The access system can include a reinforcement member fixedly secured to the connector so as to be immobile relative thereto and oriented such that when the connector is coupled with the closed intravenous catheter system, a distal tip of the reinforcement member is at or proximally spaced from a proximal surface of the valve. The access system can include a cannula movable relative to the reinforcement member from a retracted position to an advanced position. At least a portion of the cannula can be advanced distally through the reinforcement member and then through the valve and subsequently into the catheter tube as the cannula is transitioned from the retracted position to the advanced position.
