Fluid Transfer Device and Method of Use Thereof for Caustic Medication Delivery

A method of intravenously delivering a caustic medication to a patient, the method comprising:

• connecting a fluid transfer device to a catheter assembly including a catheter adapter and a catheter having a distal tip that is indwelling intravenously in 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 fluid from the fluid source to the patient when in the second position;
• connecting a fluid source to the fluid transfer device such that the fluid source is fluidly connected with the flexible tube, wherein the fluid source contains a caustic medication in fluid form;
• actuating the advancement member to move the flexible tube from the first position to the second position;
• and
• with the flexible tube in the second position, operating the fluid source to administer the caustic medication to the patient, via the flexible tube;
• wherein, in administering the caustic medication to the patient, the fluid transfer device controls one or more of an intravenous location or dispersion of the caustic medication administered to the patient, and a dilution of the caustic medication administered to the patient.
