Abstract
The system described is a positive cross identification system finding use in assuring that the proper medicaments are used for the proper patient. In this system, a patient'"'"'s identification (I.D.) number is read by an optical scanner. Next, the I.D. number of the intended recipient on medicament container label is read by the optical scanner and the identification numbers compared in an electronic comparator. If comparison is indicated, an electronically actuated lock on the medicament container is unlocked.
The lock described includes a lock body with a receptacle into which a split locking pin is introduced. An actuating pin spreads the members of the locking pin such that the locking pin cannot be removed. The locking pin can be removed only by withdrawing the actuating pin from the split members so that they are allowed to come together and be withdrawn from the aperture. Withdrawal of the actuating pin is accomplished by a solenoid actuated by the output of the comparator.
