Abstract
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.
Claims20
A catheter assembly, comprising:
- a catheter adapter comprising a proximal end, a distal end, and a lumen extending therebetween;
- a catheter extending from the distal end, the catheter comprising a proximal end, a tip, and a length of tubing therebetween, wherein the length of tubing comprises at least one position indicator to indicate a position of the catheter relative to a vasculature;
- and
- an introducer needle extending through the length of tubing and comprising a sharp distal tip configured to introduce the catheter into the vasculature.
A vascular access device to detect a catheter position within a vasculature, comprising:
- a catheter comprising a proximal end, a tip, and a length of tubing therebetween;
- and
- a position indicator disposed on an outer surface of the length of tubing, the position indicator configured to indicate a position of the catheter within a vasculature.
A method, comprising:
- providing a catheter assembly to introduce a catheter into a vasculature of a patient, the catheter assembly comprising:
- a catheter adapter comprising a proximal end, a distal end, and a lumen extending therebetween;
- a catheter extending from the distal end, the catheter comprising a proximal end, a tip, and a length of tubing therebetween, wherein the length of tubing comprises a position indicator to indicate a position of the catheter relative to the vasculature;
- and
- an introducer needle extending through the length of tubing and comprising a sharp distal tip to introduce the catheter into the vasculature at an intravenous entry site of the patient;
- securing the catheter such that the position indicator is aligned with the intravenous entry site;
- and
- automatically monitoring a location of the position indicator relative to the intravenous entry site to detect catheter dislodgement.
