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： 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.

摘要： A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.

摘要： A delivery device for delivering an instrument through an intravenous catheter may include a housing, a rotary element disposed within the housing, and an instrument. In some embodiments, the rotary element may include a groove, which may extend around at least a portion of the circumference of the rotary element. In some embodiments, the instrument may be disposed within the groove and/or between the rotary element and the housing. In some embodiments, in response to rotation of the rotary element with respect to the housing, the instrument may be advanced distally through an port of the housing. In some embodiments, the instrument may include a guidewire, a probe, tubing, or a light tube.

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： 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 vascular access device may include a housing, which may include a proximal end, a distal end, and a slot. The distal end of the housing may be configured to be coupled to a catheter assembly. The vascular access device may also include an instrument disposed within the housing. The instrument may include a catheter or a probe. The instrument may include a proximal end and a distal tip. The proximal end of the instrument may extend through the slot and may be configured to move along the slot to move the instrument from a proximal position to a distal position. In response to movement of the proximal end of the instrument from the proximal position to the distal position, the catheter may be advanced beyond the distal end of the housing into the catheter assembly and/or vasculature of a patient.

摘要： A catheter adapter may include a catheter adapter body and a catheter adapter channel formed within the catheter adapter body. The catheter adapter body may include a proximal end, a distal end, an inferior surface, and a superior surface. The inferior surface of the catheter adapter body may be configured to abut against a surface area of a patient's skin, and an angle formed between the surface area of the patient's skin and a longitudinal axis of the catheter adapter channel may be greater than 4 degrees.
