1. A system for delivering infusate to a patient, the system comprising:
- an infusion device;
an infusion set;
a slide clamp corresponding to the infusion set;
a signaling component disposed on the clamp and encoded with a key, the key including an encryption algorithm and a valid number from a valid number table, wherein;
(i) the encryption algorithm encrypts the valid number, and (ii) the signaling component identifies the infusion set using the encrypted valid number of the encoded key;
a detection device to read the signaling component and configured to generate a signal, the detection device operable with a decryption algorithm, to allow;
(a) the decryption algorithm to determine a decrypted valid number by decrypting the encrypted valid number from the encoded key, and(b) the decrypted valid number to be compared to the valid number table; and
wherein, based upon the decrypted valid number comparison, the signal generated by the detection device either validates or rejects use of the infusion set with the infusion device.

Abstract
A system and method for automatically delivering an infusate to a patient is disclosed. The system includes an infusion set and an infusion device. A signaling component disposed on an infusion set component identifies the infusion set and is encrypted for security. The encryption may include both an encryption algorithm and a valid number algorithm. A detection device operatively connected to the infusion device decrypts and detects the signaling component and identifies the infusion set. The infusion device is then configured to operate according to an administration protocol suitable for the infusion set and an infusion device, such as an infusion pump.
