Abstract

A medication drawer, a related medication packaging strip, and a related method of handling a medication packaging strip.

Claims

1. A medication drawer, comprising:

a housing including a main body, and a front cover coupled to the main body and having a base wall with a packaging strip outlet therethrough;

at least one sensor disposed upstream of the outlet and operatively disposed to sense at least one sensor pickup on a medication packaging strip to be released through the outlet; and

a packaging strip guide including at least one guide surface oppositely disposed from the at least one sensor to guide the packaging strip through the outlet and to reflect light to the at least one sensor.

2. The medication drawer of claim 1, further comprising a circuit board assembly including a circuit board carrying the at least one sensor and being mounted to the front cover.

3. The medication drawer of claim 2, wherein the front cover also includes vertical flanges extending from a rear surface of the base wall of the front cover and a horizontal flange extending from the rear surface of the base wall of the front cover between the vertical flanges and across the outlet from the guide, wherein the at least one sensor is flush with a upper surface of the horizontal flange.

4. The medication drawer of claim 2, wherein the circuit board assembly also includes a light.

5. The medication drawer of claim 1, further comprising a material handler carried by the housing to convey the packaging strip out of the housing, and including a prime mover, a transmission coupled to the prime mover, laterally spaced drive elements coupled to the transmission, and laterally spaced driven elements operatively coupled to the drive elements, wherein the prime mover drives the transmission and the transmission drives the drive elements and the drive elements engage the packaging strip against the driven elements to convey the packaging strip in a direction toward the outlet.

6. The medication drawer of claim 5, wherein the drive and driven elements include gears having at least twenty-two teeth.

7. The medication drawer of claim 6, wherein the gears have forty-four teeth.

8. The medication drawer of claim 5, wherein the material handler advances the packaging strip to a release position of the packaging strip where the at least one sensor pickup on the packaging strip aligns with the at least one sensor so that a leading edge of a leading package of the packaging strip is outboard of an outer surface of the front cover and so that a leading edge of a subsequent package connected to the leading package is inboard of an outer surface of the front cover.

9. The medication drawer of claim 5, wherein the release position includes the leading edge of the subsequent package being disposed upstream of the at least one sensor.

10. The medication drawer of claim 1, wherein the packaging strip guide is a component separate from the front cover and carried by the front cover.

11. The medication drawer of claim 10, wherein the guide includes a base wall carried in a corresponding slot of the front cover, and legs extending from the base wall and terminating in the at least one guide surface.

12. The medication drawer of claim 1, wherein the packaging strip guide is composed of a die molded engineering plastic including a white dye for reflectivity.

13. The medication drawer of claim 1, wherein the front cover carries a light to indicate when the packaging strip is being released.

14. The medication drawer of claim 1 further comprising:

a material handler carried by the housing to convey the packaging strip out of the housing and including a material handler housing carrying at least one driven element;

at least one driven element carried by the housing and driven by the at least one drive element;

wherein the housing also includes strip guides extending to positions just upstream of engagement between the drive and driven elements, and other strip guides extending from positions just downstream of engagement between the drive and driven elements.

15. The medication drawer of claim 1 wherein the strip guides include upper surfaces to facilitate guiding the strip toward and away from the material handler and substantially aligned with upper surfaces of the material handler housing to support the strip.

16. The medication drawer of claim 1, further comprising:

a material handler carried by the housing to convey the packaging strip out of the housing, and including at least one drive element and at least one driven element operatively coupled to the at least one drive element, wherein the packaging strip is engaged by the drive and driven elements which are powered by a prime mover to convey the packaging strip in a direction toward the outlet;

wherein the prime mover and drive and driven elements advance the strip out of the outlet until the at least one sensor senses the at least one sensor pickup on the strip for depowering the prime mover, such that a portion of the strip projects out of the outlet to allow a user to grasp the strip, and pull and tear an individual package away from the rest of the strip.

17. The medication drawer of claim 16, wherein when the individual package has been removed, the at least one sensor senses the absence of the at least one sensor pickup by way of the at least one reflector of the packaging strip guide for maintaining the prime mover in a depowered state.

18. The medication drawer of claim 17, wherein once the individual package is removed from the rest of the strip, a leading edge of a subsequent package is positioned downstream of the drive and driven elements but upstream of the outlet to prevent pulling of the strip out of the outlet with fingers.

19. A medication packaging strip, comprising

a base;

a cover over at least a portion of the base; and

a plurality of spaced apart tear lines defining a plurality of individual packages each having a leading edge, a trailing edge, and side edges extending between the front and trailing edges, a upper surface, a bottom surface, and at least one sensor pickup located closer to the trailing edge than to the leading edge, and a dose of medication disposed between corresponding portions of the cover and the base.

20. The medication packaging strip of claim 19, wherein the at least one sensor pickup includes a pair of laterally spaced apart sensor pickups at opposite side edges.

21. A method of handling a medication packaging strip, comprising:

providing a housing including a main body and a front cover coupled to the main body and having a base wall with a packaging strip outlet therethrough;

providing at least one sensor upstream of the outlet and operatively disposed to sense at least one sensor pickup on a medication packaging strip to be released out of the outlet;

providing a packaging strip guide including at least one guide surface oppositely disposed from the at least one sensor to guide the packaging strip through the outlet and to reflect light to the at least one sensor;

sensing the absence of the at least one sensor pickup by way of the at least one guide surface of the packaging strip guide for maintaining the prime mover in one of a powered or depowered state; and

conveying the packaging strip out of the housing using a prime mover, at least one drive element, and at least one driven element operatively coupled to the at least one drive element, wherein the packaging strip is engaged by the drive and driven elements which are powered by the prime mover to convey the packaging strip in a direction toward the outlet until the at least one sensor senses the at least one sensor pickup.

22. The method of claim 21, further comprising sensing with the at least one sensor, the at least one sensor pickup on the strip for depowering the prime mover such that a portion of the strip projects out of the outlet to allow a user to grasp the strip, and pull and tear an individual package away from the rest of the strip.

23. The method of claim 22, further comprising, when the individual package has been removed, sensing the absence of the at least one sensor pickup by way of the at least one reflector of the packaging strip guide for maintaining the prime mover in a depowered state.

24. The method of claim 23, wherein once the individual package is removed from the rest of the strip, a leading edge of a subsequent package is positioned downstream of the drive and driven elements but upstream of the outlet to prevent pulling of the strip out of the outlet with fingers.
