No. 7,467,093 to Newton et al describes a method of tracking and dispensing medical items for use by patients associated with a health care institution that includes storing in a data store in connection with a computer data representative of patients and medical items prescribed for the patients. Authorized users such as a nurse, are enabled to dispense prescribed items for patients through medical item dispensers. A record is included in the data store that the medical items have been dispensed. In an exemplary system medical items that have been dispensed are tracked to the point of giving the item to the patients using portable terminals that are carried to the bedside of the patients. The activity of giving the appropriate medical item to each respective patient is recorded in the portable terminal as medical items are given to a plurality of patients. The data stored in the portable terminal concerning the giving of medical items to patients is communicated through the system and stored in the data store to provide a record that the medical items which were dispensed for a patient were actually administered. In an alternative form of the system patients are enabled to dispense medications on an outpatient basis through a self-service medical item dispenser. In a method of operating such a system a benefit plan associated with the patient is determined from rules stored in connection with data representative of the benefit plan. Payment for dispensed medications is provided by the benefits provider associated with the patient's benefits plan and a co-payment is made by the patient from a credit or debit card account.

No. 4,558,303 to Fielden describes an analogue voltage-to-digital voltage converter that has a voltage divider with a plurality of stages each providing an output voltage for comparison with the unknown voltage and in addition provides interpolation between the output voltage to improve the accuracy. Interpolation is effected by adding a ramp voltage to the unknown ramping through a magnitude equivalent to the voltage of at least one stage. With one tap on the voltage divider selected, comparison of the unknown plus ramp voltage is effected successively as the voltage ramps. By noting when the combined voltage reaches the level of one of the divider output voltages and by counting the number of comparisons made from the time when the ramp voltage is at a predetermined magnitude and comparing this with the time taken to ramp through one or a plurality of whole divider stages, determination can be made of the magnitude of the unknown voltage to a fraction of a stage.
U.S. Pat. No. 4,490,711 to Johnston describes a structure provided for assisting a person in keeping track of appointments, times for taking medication or the times for turning on electrical equipment or such. The structure comprises an electronic circuit capable of generating signals representing up to N different pre-set times at which specific events are to occur where N is a selected positive integer such as 20. Switches are then provided, each switch corresponding on a one-to-one basis to a unique pre-set time, such that the user can set those switches corresponding to the pre-set times at which the user desires events to take place. An alarm is provided to indicate in sequence when the actual time corresponds to the pre-set time corresponding to each set switch. The user can only shut off the alarm when the alarm is sounding and the system will then automatically record the number of times during which the alarm has come on and the user has responded to the alarm by silencing it thereby to provide a cumulative count of total events to which the user has responded. A doctor can then check the cumulative count to ensure that a patient has presumptively taken medicines prescribed at selected times in accordance with the programmed schedule on the structure. Because the alarm can only be silenced when it is sounding, accidental silencing of the alarm at any time is prevented. The structure of this invention combines the convenience and ease of an electronic alarm system with the simplicity and permanence of a written record of events.

Additional features, advantages, and embodiments of the invention may be set forth or apparent from consideration of the following detailed description, drawings, and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanation without limiting the scope of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate preferred embodiments of the invention and together with the detailed description serve to explain the principles of the invention. In the drawings:
The present invention is directed to unit dosage medicine dispensing devices that receive cartridges of medication dosages to be released on a timed schedule. The cartridges are safe because they are locked and are thus set up to deny access for medication abuse. The present invention dispenser devices include two separate locks, one being a multi-unit medication cartridge lock functionally connected to a CPU and positioned adjacent a cartridge receiver for locking and unlocking the medication cartridge (ergo, secure except for a professional access, such as a pharmacist, dispensary or nurse), and the other lock being a control gate mechanism connected to the CPU and to a medication release control gate (such as a toggle) to permit or prohibit activation of the gate for medication dosage release according to a timer.
The following is an example of how a present invention preferred dispenser device would work: a doctor would give the user patient a prescription for opioids or other dangerous drug, and the user patient would bring this script to the pharmacist. The pharmacist would take an empty cartridge and fill it with the correct opioid or other medicine, or would take a full cartridge from a pharma manufacturer. This cartridge would be color coded to a properly sized gate (e.g., a toggle). The pharmacist would then assemble both the Toggle and the Cartridge to the dispensing package. Both would be locked in place and could not be removed without breaking the device.
The pharmacist would then, using his computer, program the unit with the prescription's dosing instructions. The complete package would then be given to the user patient for use after instruction by the pharmacist. A display clock on the unit (a countdown clock is preferred) would tell the user patient when he could access a tablet. The user patient sees the clock count down to zero, at which time the CPU would activate a gate (Toggle) with a solenoid or equivalent mechanism) for medication release. The patient would have 1 hour to access the dose or the unit would automatically re-lock until the next dose is due. To access a tablet, the user patient would tilt the unit, allowing a single tablet to enter the Toggle chute, then push down on the toggle and one tablet would be dispensed. The Toggle is spring loaded and, when released by the user patient, it would automatically re-lock until the next dose is due.
When the cartridge is empty, the user patient would bring the device back to the pharmacy for either a re-fill or return of the deposit on the unit. If the dispenser or cartridge shows damage or tampering evidence, the refund would not be issued and a re-fill would not be honored. In preferred embodiments, the Toggle and the Cartridge will be made of clear plastic, allowing the user patient to see the tablet move to the slot in the Toggle for dispensing. Also, in some preferred embodiments, an additional button must be pushed to open the gate (Toggle), and this creates a simultaneous dual action child resistant requirement.
