Compounding device system
A system for compounding medications. The system includes one or more compounding devices, and a central computer system. The central computer system receives requests, at least some of which require the compounding of one or more medications, and pushes assignments of respective compounding tasks to the one or more compounding devices. The assignments are made in accordance with a set of rules designed to promote efficient use of compounding resources.
1. A pharmaceutical compounding device, comprising:
an infrared area light source;
an infrared digital camera;
a visible light digital camera;
a source of visible light positioned adjacent the visible light digital camera;
a viewing area between the infrared area light source and the infrared digital camera; and
a controller programmed to control the infrared area light source and the infrared digital camera to take a first photograph of an item in the viewing area such that the item is backlit by the infrared area light source, and to take a second photograph of the viewing area using the visible light digital camera, and to control the source of visible light.
2. The pharmaceutical compounding device of claim 1 , wherein:
the pharmaceutical compounding device is a compounding assistance device comprising a display; and
the controller is further programmed to guide a user of the device through a compounding task using prompts shown on the display.
3. The pharmaceutical compounding device of claim 1 , wherein the pharmaceutical compounding device is a compounding robot.
4. The pharmaceutical compounding device of claim 1 , wherein the second photograph comprises a color photograph.
5. The pharmaceutical compounding device of claim 1 , wherein the second photograph is associated with the first photograph.
6. The pharmaceutical compounding device of claim 1 , wherein the controller is further programmed to automatically analyze at least one of the first photograph or the second photograph.
7. The pharmaceutical compounding device of claim 6 , wherein the controller is programmed to automatically analyze at least one of the first photograph or the second photograph to determine a volume of liquid in a syringe received in the viewing area.
8. The pharmaceutical compounding device of claim 6 , wherein the controller is programmed to automatically analyze at least one of the first photograph or the second photograph to ascertain a size and position of a syringe received in the viewing area in the at least one of the first photograph or the second photograph.
9. The pharmaceutical compounding device of claim 8 , wherein automatically analyzing the at least one of the first photograph or the second photograph to ascertain the size and position of a syringe received in the viewing area in the at least one of the first photograph or the second photograph comprises comparing previous photographs of syringes to the at least one of the first photograph or the second photograph.
10. The pharmaceutical compounding device of claim 8 , wherein automatically analyzing the at least one of the first photograph or the second photograph to ascertain the size and position of a syringe received in the viewing area in the at least one of the first photograph or the second photograph comprises comparing a synthetic syringe image to the at least one of the first photograph or the second photograph.
11. The pharmaceutical compounding device of claim 6 , wherein the controller is programmed to automatically analyze at least one of the first photograph or the second photograph to ascertain whether a needle is attached to a syringe received in the viewing area.
12. The pharmaceutical compounding device of claim 11 , wherein automatically analyzing the at least one of the first photograph and the second photograph to ascertain whether the needle is attached to the syringe comprises:
identifying an expected location of the needle; and
evaluating pixel brightness at the expected location of the needle.
13. The pharmaceutical compounding device of claim 12 , wherein evaluating pixel brightness at the expected location of the needle comprises:
identifying a column line; and
evaluating pixel brightness along the column line.
14. The pharmaceutical compounding device of claim 13 , wherein evaluating pixel brightness along the column line comprises identifying abrupt light-to-dark and dark-to-light transitions.
15. The pharmaceutical compounding device of claim 13 , wherein automatically analyzing the at least one of the first photograph or the second photograph to ascertain a size and position of the syringe in the at least one of the first photograph or the second photograph comprises:
identifying a column line extending across the syringe; and
evaluating pixel brightness along the column line.
16. The pharmaceutical compounding device of claim 15 , wherein evaluating pixel brightness along the column line comprises identifying abrupt light-to-dark and dark-to-light transitions.
17. The pharmaceutical compounding device of claim 15 , wherein evaluating pixel brightness along the column line comprises identifying a size of a plunger of the syringe.
18. The pharmaceutical compounding device of claim 17 , wherein automatically analyzing the at least one of the first photograph or the second photograph to ascertain the size and position of the syringe in the at least one of the first photograph or the second photograph further comprises comparing the size of the plunger of the syringe to stored dimensions of standard syringes.
