Fluid Transfer Device And Method Of Use Thereof For Delocalized Caustic Medication Delivery

A system for intravenous delivery of a caustic medication to a patient, the system comprising:

• a catheter assembly including a catheter adapter and a catheter positionable intravenously in the patient;
• a fluid source containing a caustic medication;
• and
• a fluid transfer device coupleable to the fluid source and to the catheter assembly and operable to administer the caustic medication to the patient, the fluid transfer device comprising:
• a flexible tube configured to be inserted within the catheter, the flexible tube in fluid communication with the fluid source;
• a housing having a proximal end and a distal end and defining an inner volume configured to movably receive the flexible tube;
• a coupling device positioned at the distal end of the housing and configured to couple the housing to the catheter assembly;
• and
• an advancement member configured to move relative to the housing to move the flexible tube between a first position, in which a distal end of the flexible tube is disposed within the housing or within the coupling device, and a second position, in which the distal end of the flexible tube is disposed within the catheter or past a distal tip of the catheter, with the flexible tube able to transfer the caustic medication from the fluid source to the patient when in the second position;
• wherein, with the flexible tube at the second position, the fluid transfer device is configured to further incrementally advance the flexible tube distally out past the distal tip of the catheter by a finite distance, to reposition the distal end of the flexible tube within a vein of the patient during administering of the caustic medication.
