Abstract

The present device is a magazine (10) which includes housing defining a medication storage area. An access door (22) is provided in the housing to gain access to stock the storage area with unit dose medication containers (34). The housing defines an open lower periphery which is covered by at least one locking mechanism having a release door (156). The locking mechanism includes a plurality of cams (166, 174, 186) cooperatively contained such that upon sequential operation, the release door (156) opens the lower periphery which allows the unit dose medication containers (34) to fall.

Claims

1. A magazine for storing and dispensing unit dose medication containers comprising:

housing defining a medication storage area, the housing further defining an aperture at the lower periphery of the storage area and a second aperture near the upper periphery of the storage area;

an access door contained on the housing covering the second aperture which opens to gain access to the storage area;

a release door extending over the lower aperture;

a cam member contained in cooperative association with the release door such that upon actuation of the cam member, the release door opens the lower aperture; and

a locking mechanism having a rest position in which operation of the cam member is prevented and an operative position in which operation of the cam member is allowed;

such that only after the locking member is in the operative position can the cam member be actuated to open the lower aperture.

2. The magazine of claim 1 further including a second release door extending over the lower aperture, a second cam member contained in cooperative association with the second release door such that upon actuation of the second cam member, the second release door opens, and a second locking mechanism having a rest position in which operation of the second cam member is prevented and an operative position in which operation of the second cam member is allowed.

3. The magazine of claim 1 wherein the locking mechanism includes a link actuator cam which in a rest position obstructs the operation of the cam member such that the link actuator cam must be sequentially operated first to release the cam member the cam member being operated last to open the release door.

4. The magazine of claim 3 wherein the locking mechanism further includes a lock cam which locks the cam member such that the link actuator cam must disable the lock cam to release the locked cam member.

5. The magazine of claim 3 wherein the link actuator cam includes a stepped lower periphery which controls the operation of the link actuator cam and the cam member includes a stepped lower periphery which controls the operation of the cam member, the link cam stepped portion extending a distance further than the cam member stepped portion such that sequential operation of the link cam and the cam member is effectuated.

6. The magazine of claim 5 wherein the stepped lower periphery of the link actuator cam extends lower than the stepped lower periphery of the main cam.

7. The magazine of claim 3 further wherein the sequential operation of the cams is caused by a stepped engaging member which contacts and therefor causing operation of the link actuator cam prior to contacting and causing operation of the cam member.

8. A method for stocking unit dose medication containers comprising:

placing a plurality of medication containers in a magazine having a storage area for holding the medication containers, an access door for accessing the storage area, and a locking mechanism for containing the medication containers in the storage area;

storing the medication containers in the magazine;

transporting the magazine to the site of actual use; and

loading the medication dispensers into an automatic dispensing apparatus by releasing the locking mechanism to allow a cam member to actuate a release door to allow the medication dispensers to fall by gravity into a cartridge contained in the automatic dispensing apparatus.

9. The method of claim 8 wherein the step of loading the medication dispensers into an automatic dispensing apparatus further includes the steps of:

activating a link actuator cam to unlock the cam member; and

activating the can member to release the medication dispensers.

10. The method of claim 9 further wherein activation of the link actuator cam deactivates a lock member cam which unlocks the cam member.
