Abstract

A portable, medication dispensing device which dispenses prepackaged pill strands of medication from a secure, storage compartment through a mechanism which physically limits the quantity dispensed per a pre-programmed protocol. The device has a detachable storage component which can be filled by trained clinical or pharmacy staff, which can be locked. The device has a dispensing mechanism, which employs a user-powered, hub to advance a pill strand of pre-packaged medications, when appropriate. This advancing hub is secured from advancing inappropriately by a locking mechanism where a sturdy piston is moved into and out of recesses in the rounded surface of the hub. The device also contains standard electronic components, including a power source, central processing unit (CPU), visual and auditory outputs, and communications ports.

Claims

1. A portable medication dispenser, comprising:

a detachable storage chamber storing pills packaged in a pill strand, the detachable storage chamber having a first opening for the pill strand to pass through and a docking section of the storage chamber; and

a main body, comprising;

an external rotating knob;

an opening for the pill strand to pass through;

a docking section to secure to the docking section of the storage chamber;

a rotating hub rotatable by the external knob, the rotating hub comprising cogged edges for engaging with the pill strand and recesses spaced apart a predetermined distance along the center of a curved surface of the rotating hub;

a locking rod under spring tension to be positioned securely within the recesses of the rotating hub to lock the rotating hub from advance;

a controlling mechanism controlling locking rod by programming to retract the locking rod to allow advance of the rotating hub at predetermined times; and

an extruding rod under spring tension movable by force to move in a direction to force a pill out of the pill strand into a holding chamber.

2. The portable medication dispenser of claim 1, wherein the portable medication dispenser is programmable to control the locking rod and controlling mechanism to control the advancement of the rotating hub and pill strand.

3. The portable medication dispenser of claim 1, wherein the controlling mechanism is an electromechanical solenoid.

4. The portable medication dispenser of claim 1, further comprising a visual display.

5. The portable medication dispenser of claim 4, wherein the visual display is an LCD display.

6. The portable medication dispenser of claim 1, further comprising auditory outputs.

7. The portable medication dispenser of claim 1, further comprising input/output ports.

8. The portable medication dispenser of claim 1, further comprising a power supply.

9. The portable medication dispenser of claim 1, wherein the predetermined distance between recesses corresponds to the size of a single unit of the pill strand.

10. The portable medication dispenser of claim 1, further comprising a locking mechanism locking the storage chamber to the main body at the docking section of the storage chamber and the docking section of the main body;

11. The portable medication dispenser of claim 10, wherein the locking mechanism comprises:

a lug coupled to the docking section of the storage chamber;

a rotating sleeve in the docking section of the main body rotatable around the lug;

a key hole and lock in the docking section of the main body; and

a key for rotating the rotating sleeve around the lug.

12. The portable medication dispenser of claim 1, further comprising a ratchet assembly restricting movement of the rotating hub in a single direction.

13. The portable medication dispenser of claim 12, wherein the ratchet assembly comprises a gear and pawl.

14. The portable medication dispenser of claim 12, wherein the ratchet assembly comprises a sensor measuring the advance of the rotating hub.

15. The portable medication dispenser of claim 12, wherein the ratchet assembly comprises an electrical motor.
