Abstract

A medication dispenser provides automation to the steps of locating and acquiring unit-based doses of certain medications to be administered to a patient. The dispenser includes a frame and one or more cartridges that may be mounted onto the frame. A set of slots sized for holding unit-based doses of medication extend through a body portion of the cartridge. A movement device is also positioned relative to the frame and is configured to induce movement of selected unit-based medication doses out of associated slots in the cartridge, so that the dispensed doses may be retrieved.

9. The apparatus of claim 8, wherein the device inducing medication movement includes:

an effector; and

at least one motor for positioning the effector adjacent to the preselected slot housing the identified at least one of the unit-based doses of medication;

wherein the electronic controls are connected with the motor and generate additional command signals to direct effector positioning.

10. The apparatus of claim 9, wherein the effector utilizes air pressure to impart a force on the identified at least one of the unit-based doses of medication to be moved from the preselected slot holding the identified at least one of the unit-based doses of medication.

11. The apparatus of claim 9, wherein the plurality of slots of the at least one cartridge of the plurality of cartridges are arranged in a pattern, and wherein the at least one motor includes an x-y motor system for positioning of the effector adjacent to the preselected slot in the pattern that houses the identified at least one of the unit-based doses of medication.

12. The apparatus of claim 1, wherein the device inducing medication movement includes:

at least one effector; and

at least one motor for positioning the at least one effector adjacent to the preselected slot housing the identified at least one of the unit-based doses of medication.

13. The apparatus of claim 12, further comprising electronic controls connected with the at least one motor for receiving an input regarding the identified at least one of the unit-based doses of medication to be dispensed and generating a command signal directing positioning of the at least one effector by the at least one motor in accordance with the input received.

14. The apparatus of claim 12, wherein the at least one effector includes a plurality of effectors mounted onto a support, and the at least one motor moves the support along an axis to position one effector of the plurality of effectors adjacent to the preselected slot housing the identified at least one of the unit-based doses of medication.

15. The apparatus of claim 1, wherein the device inducing medication movement includes:

an effector;

a first motor;

a first support driven by the first motor and onto which the effector is mounted;

a second motor;

a second support driven by the second motor and onto which the first support and the first motor are mounted, wherein the first motor moves the effector in a first dimension and the second motor moves the effector in a second dimension to position the effector adjacent to the preselected slot of one cartridge housing the identified at least one of the unit-based doses of medication to be moved from the preselected slot.

16. The apparatus of claim 1, wherein the device inducing medication movement includes:

a plurality of effectors laterally adjacent to one another;
