Abstract

Disclosed herein is an identification system for an infusion set when the infusion set is installed in a pump. The identification system includes a pump, at least one sensor, a catheter, a tube and an alarm. The pump includes at least one sensor disposed thereon, which is in communication with the alarm. The catheter includes a distal end adapted for insertion into a body, and a proximal end opposite the distal end. The tube is operatively configured at a first end to removeably attach to the proximal end of the catheter, and the tube further includes a second end proximate to the sensor(s) on the pump. The sensor(s) are operatively configured to receive a signal generated at the first end or along a length of the tube, and to trigger the alarm upon receiving the signal so as to identify the corresponding pump.

Claims

1. A method for identifying a pump that corresponds with an infusion set including a catheter having a distal end configured for insertion into a patient'"'"'s body, the method comprising:

operatively connecting the pump and the catheter via a tube external to the patient'"'"'s body;

operatively disposing at least one sensor on the pump and in operative communication with the tube;

intentionally generating at least one of a vibration or pressure pulse within or along the tube external to the pump;

automatically triggering an alarm at the pump in response to the at least one sensor receiving the at least one of the vibration or the pressure pulse transmitted within or along the tube; and

identifying the pump based on the triggered alarm.
