Locked, Controlled Time-Dose Tablet Dispenser

DeJonge Associates has developed a tablet dispenser that can be used to make prescription drugs available in a controlled, timely manner that closely follows the doctor’s orders.




This tablet dispenser is designed to reduce prescription opioid addiction. It is not, however, designed for people who already have an opioid addiction. It is designed for patients with legitimate pain-relief needs that require prescription opioids.

Many people suffering from opioid addiction have become addicted due to careless mis-dosing or overuse. This dispenser design - available at the pharmacy with a deposit - controls the availability of medication and reduces potential for overuse.

After all tablets have been used as prescribed, the patient returns the unit to the pharmacist to receive a refill; or to retrieve a deposit if the there are no refills left on the prescription.

If the unit is damaged or otherwise tampered with, the patient forfeits the deposit, the prescription is not refilled, and the physician is notified.

See the dispenser usage illustrations and demonstration video below. Please contact DeJonge Associates for additional information.

Locked, Controlled Time-Dosed Tablet Dispenser: How it Works

1. The pharmacist uses a computer to interface with the dispenser via USB or wireless connection. By entering a code the pharmacist sets the unit to dispense tablets at specific time intervals. The pharmacist can also unlock and release the tablet cartridge for filling.

5. The timer counts down to availability of next dose, which is displayed on the unit and the indicator light shows red. At time of availability the display shows 000, at which time the patient may load a tablet into the toggle and push the unlock button. The indicator light then turns green and the device unlocks the toggle for a single tablet to be dispensed within a period of up to one hour.

6. The unit is tilted to load a tablet into the dispensing slot. The toggle switch will not operate without a tablet in this slot.

7. The patient pushes the toggle to release the tablet.

8. The timer then automatically resets to the next available dosage time (8 hours shown here) and the toggle switch locks. Please note that only the pharmacist can release the tablet cartridge by using the code and a computer connection.

9. A review of the initial steps by the pharmacist follows...

While using the computer connection the pharmacist can also view data about the how the unit was used, including:
- When each pill was taken
- If a dose was skipped
- Battery life of unit

It is also possible for the pharmacist to unlock the dispenser at initial pick up/presentation, so the first dose can be taken within one hour.

11. After all tablets have been used as prescribed, the patient returns the unit to the pharmacist to receive a refill; if no refills remain on the prescription the unit is returned and the deposit refunded. If the unit is damaged or otherwise tampered with, the patient forfeits the deposit, the prescription is not refilled, and the physician is notified.
