Patent ID: 6899695

Claim:
A patient controlled fluid medication security apparatus, comprising: a) a reservoir for a fluid medication, b) a pump operatively associated with said reservoir for pumping fluid from said reservoir on command, c) a microphone for receiving voice sound from a voice source and converting it to an electrical signal representative of the voice pattern of the voice source, d) a programmable microprocessor programmable by an authorized operator to set and lock a dosage of medication regime for a patient, e) digital memory storage operatively associated with said microprocessor and in electrical communication with said microphone, f) a program of instructions for said microprocessor for causing said microprocessor to receive and analyze an electrical signal from said microphone, to produce digital data representing a learned voice print of a voice source, to transfer said data to said storage, and to cause said microprocessor, upon receipt of an electrical signal from said microphone subsequent to having committed a learned voice print to memory storage, to produce a test voice print representing the subsequent signal from a voice source, to retrieve said learned voice print from storage and to determine whether a sufficient match exists between the learned voice print and the test voice print, and if so, to examine the programmed medication regime to determine whether to instruct the pump to discharge a dosage of said medication, and g) a source of electrical power for operating said microprocessor.
