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. An identification system for an infusion set when the infusion set is installed in a pump, the identification system comprising:

a pump having at least one sensor disposed thereon, the at least one sensor being in communication with an alarm;

a catheter having a distal end and a proximal end, the distal end of the catheter adapted for insertion into a body; and

a tube having a first end that is removeably attached to the proximal end of the catheter, and a second end proximate to the at least one sensor;

the at least one sensor being operatively configured i) to receive a signal generated at the first end or along a length of the tube, and ii) to trigger the alarm upon receiving the signal.

2. The identification system as defined in claim 1 wherein the alarm is a visual alarm.

3. The identification system as defined in claim 1 wherein the alarm is an audible alarm.

4. The identification system as defined in claim 1 wherein the alarm is text generated on a user interface of the pump.

5. The identification system as defined in claim 1 wherein the at least one sensor is a pressure sensor.

6. The identification system as defined in claim 1 wherein the at least one sensor is an accelerometer.

7. The identification system as defined in claim 1 wherein the at least one sensor is an accelerometer and a pressure sensor.

8. The identification system as defined in claim 1 wherein the sensor is operatively configured to sense heart and respiratory rates as well as loss of IV connection to a vein of the body.

9. A method for identifying a pump that corresponds with an infusion set including a catheter, the method comprising:

operatively connecting the pump and the catheter via a tube;

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

generating at least one of a vibration or pressure pulse within or along the tube; and

automatically triggering an alarm 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.

10. The method as defined in claim 9 wherein the generating of the at least one vibration or pressure pulse is intentional.
