Today’s invention offers a way to limit the amounts of prescription medicines in circulation.
A medical practitioner would hand you a disc-shaped, steel case of the type shown, containing a limited number of the required tablets or capsules.
The case has to be inserted into a disk drive and left there until empty.
The computer runs some downloadable code which unlocks a rotating magazine within the case and turns the disk drive spindle at a fixed rate of say one revolution per day.
This ejects one pill after the next so that the rate of consumption is limited and makes overdosing or reselling very difficult. It also reduces the opportunities for taking out-of-date medicines.
