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.

A device (100) having a proximal end (20) and end a distal end (40) for withdrawal of a liquid sample, fractionation, and separation of one or more fractions comprising: a piston assembly (300) comprising a piston (302) dismountably attached at its proximal end (20) to an actuating rod (350); a container (200) having a body (202) disposed with a cylindrical chamber (204) for slidable movement of the piston (302) therein; wherein the cylindrical chamber (204) is provided at the distal end (40) with a resealable septum (410) for co-operation with a puncture needle assembly (600) for withdrawal of the liquid sample, an at the proximal end (20) with a stop member (206), which stop member (206) limits movement of the piston (300) in a proximal direction, wherein the container body (202) is dimensioned to fit inside a centrifuge rotor, and is configured for breakability into two parts at a temperature of 0 deg C. or lower at a breakable zone (210).

An intravenous catheter device may include a guidewire for actively repositioning the catheter tip. A guidewire assembly may be configured to enable a clinician to actively reposition the catheter tip by moving proximal ends of segments of the guidewire. By repositioning the catheter tip, the guidewire assembly may facilitate the collection of a blood sample or the injection of a fluid through the catheter even in instances when the catheter tip has become occluded.

A catheter extension set may include a housing, which may include a distal end, a proximal end, and a lumen. The catheter extension set may include a distal connector coupled to the distal end of the housing and configured to couple to a catheter assembly. The catheter extension set may include a handle, an advancement element, and an instrument. The instrument may extend through a U-shaped channel of the advancement element and may include a fixed first end and a second end. A translation feature may be disposed between the handle and the housing and within a pocket of the advancement element such that in response to distal movement of the handle a first distance, the advancement element moves distally within the lumen the first distance and the second end of the instrument advances distally a second distance. The second distance may be at least twice the first distance.

A fluid transfer device includes a syringe barrel having a chamber, a first plunger slidably movable inside the chamber, and a second plunger slidably movable inside the chamber. The distal end portion of the first plunger is engageable with the proximal end portion of the second plunger such that when the distal end portion of the first plunger and the proximal end portion of the second plunger are engaged, the second plunger is movable by the first plunger. A check valve may be incorporated into the distal end portion of the second plunger to allow a fluid to pass therethrough in a direction towards the proximal end portion of the second plunger and prevent a fluid to pass therethrough in a reverse direction. A fluid transfer assembly and a sampling method are also described.

A medical device is configured to be attached to a part of a circulation circuit of an extracorporeal circulation device and to be inserted with an insertion member for performing a test related to blood clotting, and includes a storage portion configured to store a blood, and a main body portion configured to drop the blood stored in the storage portion onto the insertion member.
