  • Publication number: 20210228121
    Abstract: A vascular access device may have a vented blood collection port. The vented blood collection port can be provided on a side port of the vascular access device that is positioned between a catheter adapter and an extension set. The side port provides separate fluid pathways for collecting blood and injecting fluids to thereby isolate the blood from the extension set. The vented blood collection port may be provided in the form of a septum housing that moves from a blood collection position to a fluid injection position. When in the blood collection position, the septum housing may enable the extension set to be primed and remain primed during a blood draw.

  • Publication number: 20210212618
    Abstract: An extension set is configured to improve patency of a vascular access device. An extension set may include a probe that can be selectively advanced through a vascular access device to which the extension set is connected. The extension set may include an integrated device, or may be configured to receive a device, for collecting blood from or injecting a fluid into a patient's vasculature. Because the probe can be selectively advanced into the patient's vasculature, a blood collection or fluid injection can be performed via the vascular access device even when an occlusion has formed that is blocking the fluid pathway through the vascular access device.

  • Publication number: 20210213268
    Abstract: A system for accessing a patient's vascular system may have a tube with a wall that defines an exterior surface and lumen with a proximal end and a distal end, and a guidewire that is deployable, by sliding distally, from a retracted position in which the guidewire resides in the lumen, to a deployed position in which the guidewire extends beyond the distal end. The system may further have a retraction mechanism that can be actuated to retract the guidewire from the deployed position to the retracted position, or a protective shield that can be actuated to extend distally from the distal end of the tube to cover the guidewire in the deployed position.

  • Publication number: 20210186394
    Abstract: A catheter extension set may include a distal end, which may include a luer adapter configured to couple to a catheter adapter. The catheter extension may also include a proximal end, which may include a blood collection device. The blood collection device may include a needle configured to receive a blood collection container. The catheter extension may include one or more extension tubes extending between the distal end and the proximal end. The catheter extension set may increase flow resistance, which may reduce a risk of hemolysis when there is a high-pressure differential within the catheter extension set. After a pressure differential within the catheter extension set is lowered, the catheter extension set may decrease flow resistance, which may facilitate more rapid blood collection.

  • Patent number: 11040186
    Abstract: Pinch-style clamps can be designed for use in clamping or occluding plastic tubing, such as intravenous tubing. These pinch clamps can include a soft, polymer material applied to various surfaces of the pinch clamp to prevent abrasion or irritation to the patient, increase friction between the pinch clamp and the user operating said pinch clamp, increase friction between engaged surfaces of the pinch clamp to prevent premature or unintended disengagement of the clamp, or increase friction between the outer surfaces of the tubing and the clamping surfaces of the clamp. Various features or components can be employed to prevent lateral disengagement of the pinch clamp. A pinch clamp may also be configured with rounded outer edges to enhance patient comfort.

  • Publication number: 20210137433
    Abstract: A vacuum tube receiver can include a housing that has a proximal end and a distal end. The housing can include a hollow interior and a proximal opening for receiving a vacuum tube into the hollow interior. The distal end of the housing can form an adapter for coupling the vacuum tube receiver to an intravenous system. The vacuum tube receiver may also include one or more spikes that extend proximally into the hollow interior to form a blood flow path. The vacuum tube receiver can include a number of features to control the pressure and/or flowrate of blood into a vacuum tube.

  • Publication number: 20210138202
    Abstract: A catheter system may include a catheter adapter and a catheter extending distally from the catheter adapter. The catheter system may include a needle assembly, which may include a plug, an outer housing, and an introducer needle. An outer surface of the plug may include multiple grooves, which may be in fluid communication with the introducer needle and configured to receive blood flashback. The grooves may include a first groove having a first surface-area-to-volume ratio, and a second groove having a second surface-area-to-volume ratio. The first surface-area-to-volume ratio may be less than the second surface-area-to-volume ratio. The first groove may have a greater volume than the second groove. The outer housing may seal a top of the first groove and a top of the second groove to prevent blood from flowing out the top of the first groove and the top of the second groove.
