Abstract

Embodiments of work stations for use in medical dose preparation management system. A work station may include a camera stand. The camera stand may include a housing enclosing a camera and one or more light sources therein. As such, the camera and light sources may be directed at a medical dose preparation staging region to capture medical dose preparation images of the medical dose preparation staging region. The camera stand may include an adjustable support positionable in a plurality of positions to dispose the camera and light source relative to the medical dose preparation staging region. A base with a removable tray may be provided that include medical receptacle engagement features. The work stations may facilitate improved image quality, efficiency of work flows carried out at the work station, and administrative tasks such as cleaning.

Claims

1. A work station for use in a system for medical dose preparation management, the work station comprising:

a medication preparation staging region operable to supportably engage a medication receptacle;

an imaging device having an imaging field encompassing at least a portion of the medication preparation staging region, the imaging device being located at least partially within a housing;

at least one light source disposed in the housing, wherein the at least one light source is operable to emit light from the housing in a direction toward the medication preparation staging region;

a first polarization filter disposed between the imaging device and the medication preparation staging region; and

a second polarization filter disposed between the at least one light source and the medication preparation staging region.

2. A work station according to claim 1, wherein the imaging field extends through an opening of the housing.

3. A work station according to claim 2, wherein the first polarization filter and the second polarization filter cover at least a portion of the opening of the housing.

4. A work station according to claim 1, wherein the first polarization filter and the second polarization filter are disposed in at least partially non-overlapping relation.

5. A work station according to claim 1, wherein the first polarization filter and the second polarization filter have perpendicular polarization orientations.

6. A work station according to claim 1, wherein the imaging device is disposed in a central region of the housing opening and a peripheral region extends about the central region, and wherein a plurality of light sources are disposed in the peripheral region.

7. A work station according to claim 6, wherein the medication preparation staging region is at least partially defined by a base having a length and a width.

8. A work station according to claim 7, wherein the peripheral region extends in at least a first direction corresponding to the width of the base.

9. A work station according to claim 8, wherein the peripheral region extends in at least a second direction corresponding to one of the length of the base or a height of the medical dose preparation staging region extending from the base.

10. A work station according to claim 6, wherein the first polarization filter is disposed in the central region and the second polarization filter is disposed in the peripheral region.

11. A work station according to claim 1, wherein the imaging device has at least one fixed optical setting.

12. A work station according to claim 11, wherein the at least one fixed optical setting corresponds to a depth of field encompassing substantially the entire medical dose preparation staging region.

13. A work station according to claim 11, wherein the at least one fixed optical setting comprises at least one of an aperture setting and a focus setting.

14. A work station according to claim 1, further comprising:

a transparent shield disposed between the imaging device and the medication preparation staging region, wherein the transparent shield covers at least a portion of the imaging device corresponding to at least a lens of the imaging device, and wherein the imaging field extends through an opening of the housing.

15. A work station according to claim 14, wherein the transparent shield covers at least a portion of the opening.

16. A work station according to claim 14, wherein the transparent shield and the housing define an enclosed volume.

17. A work station according to claim 14, wherein the transparent shield and the housing define a continuous outer surface disposed about the enclosed volume.

18. A work station according to claim 1, further comprising:

a user control device for receiving a user input to initiate capture of a medical dose preparation image from a video data stream output by the imaging device;

wherein an intensity of the at least one light source is automatically modified from a default intensity of light emitted to a modified intensity of light emitted at a first predetermined period after the capture of the medical dose preparation image.

19. A work station according to claim 18, wherein the at least one light source is automatically returned from the modified intensity of light to the default intensity of light at a second predetermined period after the first predetermined period.

20. A work station according to claim 1, further comprising:

a support member extending between the base and the housing for supportably disposing the imaging device relative to the base; and

,

an umbilical at least partially disposed within the support member, wherein the umbilical includes at least one of a signal communication path and a power communication path.
