摘要： An extension set may include a clamp, which may include a housing and an actuator. The actuator may be movable between a raised position and a depressed position with respect to the housing. The actuator may include a bump profile. The extension set may include an extension tube, which may be disposed within the housing. The extension tube may include a loop. In response to movement of the actuator between the raised position and the depressed position with respect to the housing, the bump profile may progressively clamp the extension tube along the loop. The loop may facilitate an increased fluid volume flowing distally towards a catheter in response to actuating the clamp.

摘要： A delivery device for delivering an instrument into a catheter assembly may include a syringe having a barrel and a plunger movable within the barrel. In response to depression of the plunger within the barrel, an instrument may be advanced distally. The instrument may include a catheter, a probe, a light tube for disinfection, or another suitable instrument. In response to depression of the plunger within the barrel, a distal end of the instrument may move through a catheter assembly coupled to the delivery device and into vasculature of a patient.

摘要： A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

摘要： A delivery device for delivering an instrument into a catheter assembly may include a housing having a proximal end, a distal end, and a slot. The delivery device may include a guide feature, which may be disposed within the housing. The guide feature may extend through the slot. The delivery device may include an instrument disposed within the housing and extending through the guide feature. In response to movement of the guide feature along the slot in the distal direction a first distance, a first end of the instrument may be advanced in the distal direction a second distance, which may be greater than the first distance. A second end of the instrument may be stationary with respect to the housing.

摘要： An intravenous catheter system may include a catheter adapter, which may be integrated. The intravenous catheter system may also include a housing coupled to a proximal end of the catheter adapter, an introducer needle having a proximal end, a distal tip, and a needle lumen extending between the proximal end of the introducer needle and the distal tip, a guidewire disposed within the housing and the needle lumen, and a guidewire advancement element. The housing may include a proximal end, a distal end, and a slot. A proximal end of the introducer needle may be secured within the housing. The guidewire advancement element may extend through the slot and be moveable along the slot in a distal direction to move the guidewire from a retracted position to an advanced position, in which the guidewire may extend beyond the distal tip.

摘要： A patency checking system, may include a fluid path to be coupled to an intravenous (IV) device at a distal end of the fluid path; a patency port formed along a length of the fluid path; and a plunger fluidically coupled to the fluid path at the patency port to selectively draw blood into the fluid path to confirm patency of the fluid path.

摘要： An intravenous (IV) catheter system may include a catheter adapter having a proximal end and a distal end. The IV catheter system may also include a cannula extending through the catheter adapter. A proximal end of the cannula may include a notch. The IV catheter system may also include a needle hub, which may be coupled to the proximal end of the catheter adapter. The needle hub may include a flashback chamber, which may be in fluid communication with the notch when the IV catheter system is in an insertion configuration.

摘要： A catheter assembly may include a catheter adapter having a catheter extending from its distal end. The catheter may include a proximal end, a tip, and a length of tubing therebetween. The length of tubing may include one or more position indicators to indicate a position of the catheter relative to a vasculature. The catheter assembly may include an introducer needle extending through the length of tubing and comprising a sharp distal tip configured to introduce the catheter into the vasculature.

摘要： A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a distal opening, a first magnet, and a second magnet. In response to proximal withdrawal of the introducer needle, the first magnet may move towards the second magnet, which may block the distal opening and/or prevent blood from leaking out the distal opening.
