Abstract

An automatic medication dispenser is disclosed which dispenses medication serially at preselected time intervals. The medication may be retrieved by the patient within a grace period after which time the medication returns to an inaccessible location within the device. The apparatus includes an endless chain of containers holding prepackaged medications which are moved sequentially under the control of a programmable timer from within the device to a presentation position accessible to the patient.

Claims

1. Apparatus for presenting consecutively each of a plurality of containers including the combination of:

a plurality of said containers linked in an endless chain;

stepping means including a timer adapted to move the chain intermittently to advance the containers successively to and from a fixed presentation position; and

a housing completely enclosing all of said containers except for the container in said fixed presentation position, said housing including exit and entrance openings adjacent said fixed position, said containers being adapted to close substantially said exit and entrance openings after a container has advanced to and from said fixed presentation position;

wherein the stepping means advances the containers at the end of consecutive alternating first and second time intervals, the containers and openings being spaced so that during each said first interval a container is located in said fixed presentation position and during each said second interval no container is located in said fixed presentation position.

2. The apparatus according to claim 1 in which said first and second time intervals are of unequal duration.

3. The apparatus according to claim 1 wherein said timer is programmable so that said first and second time intervals are independently adjustable.
