Abstract

The present application provides a co-infusion apparatus and a co-infusion method which can photograph an image suitable for inspecting whether or not a co-infusion process in the co-infusion apparatus is properly carried out.

First claim

What is claimed is:

1. A co-infusion apparatus for suctioning a medicine from a medicine container with an injector based on preparation data and injecting the medicine from the injector into a transfusion container, the co-infusion apparatus comprising:
a first driving portion configured to transfer one or both of the medicine container and the injector to an arbitrary position;
a second driving portion configured to handle the injector;
a suctioning control portion configured to control the first driving portion and the second driving portion to suction the medicine from the medicine container with the injector;
a transfer control portion configured to control the first driving portion to transfer, into a photographing range, the medicine container after the medicine is suctioned by the suctioning control portion and the injector in which the medicine has been suctioned; and
a suctioning timing photographing portion configured to photograph, at one time, the medicine container and the injector transferred in the photographing range by the transfer control portion,
a container position adjusting portion configured to adjust a circumferential position of the medicine container held by the first driving portion so that characters of a medicine name on the medicine container are located in the photographing range.

2. The co-infusion apparatus according to claim 1 , wherein the first driving portion includes a first robot arm and a second robot arm, each having a multiple joint structure.

3. The co-infusion apparatus according to claim 1 , wherein the transfer control portion allows the medicine container and the injector to be arranged in the photographing range so that characters of a medicine name on the medicine container and characters of a scale of the injector are directed toward the same direction.

4. The co-infusion apparatus according to claim 3 , wherein the transfer control portion allows the medicine container and the injector to be arranged in the photographing range so that vertical directions of the characters of the medicine name on the medicine container and the characters of the scale of the injector and a vertical direction in the photographing range are the same.

5. The co-infusion apparatus according to claim 1 , wherein the transfer control portion allows the medicine container and the injector to be arranged in the photographing range so that the medicine container and the injector are aligned in a direction perpendicular to a longitudinal direction of the injector.

6. The co-infusion apparatus according to claim 1 , wherein the transfer control portion allows the first driving portion to keep holding the medicine container and the injector until the medicine container and the injector are photographed by the suctioning timing photographing portion after the medicine is suctioned from the medicine container with the injector.

7. The co-infusion apparatus according to claim 1 , further comprising:
an inspection image display portion configured to display an image photographed by the suctioning timing photographing portion as an inspection image.

8. The co-infusion apparatus according to claim 7 , wherein the inspection image display portion allows a medicine name and a medicine volume contained in the preparation data to be displayed together with the inspection image.

9. The co-infusion apparatus according to claim 8 , further comprising:
a medicine weight capturing portion configured to capture a weight of the medicine injected from the medicine container into the transfusion container with the injector, wherein
the inspection image display portion allows the weight of the medicine captured by the medicine weight capturing portion and a predetermined acceptable range for the weight of the medicine to be displayed together with the inspection image.

10. The co-infusion apparatus according to claim 9 , wherein the medicine weight capturing portion calculates, as the weight of the medicine, a difference between a weight of the injector after the medicine is suctioned thereinto from the medicine container and a weight of the injector after the medicine is injected from the injector into the transfusion container.

11. The co-infusion apparatus according to claim 9 further comprising:
a weight inspecting portion configured to determine whether or not a difference between the weight of the medicine captured by the medicine weight capturing portion and a weight of the medicine corresponding to the medicine volume contained in the preparation data is in a predetermined acceptable range,
wherein
the inspection image display portion allows a determination result from the weight inspecting portion to be displayed together with the inspection image.

12. The co-infusion apparatus according to claim 11 , wherein the predetermined acceptable range is a range that is set in advance for a standard volume of each injector.

13. The co-infusion apparatus according to claim 1 , further comprising:
a whole amount obtaining timing photographing portion configured to photograph a bottom surface or a side surface of the medicine container in a state that an opening portion of the medicine container is directed toward a vertical upper direction or in a state that the opening portion of the medicine container is inclined at a predetermined angle with respect to the vertical upper direction when a whole amount obtaining process for suctioning a whole amount of the medicine contained in the medicine container with the injector based on the preparation data is carried out by the suctioning control portion.

14. The co-infusion apparatus according to claim 1 , further comprising:
a rotation driving portion configured to rotate the medicine container in a circumferential direction and a container reading portion configured to read medicine information from the medicine container rotated by the rotation driving portion, wherein
the container position adjusting portion allows the rotation driving portion to rotate the medicine container by a rotation amount predetermined for each medicine container and then stop the rotation of the medicine container after the medicine information is read by the container reading portion.

15. The co-infusion apparatus according to claim 1 , further comprising:
a tray reading portion configured to read identification information from a storage medium included in a tray on which at least one of the medicine container, a syringe of the injector, an injection needle of the injector, and the transfusion container is placed when the at least one of the medicine container, the syringe of the injector, the injection needle of the injector and the transfusion container is loaded into the co-infusion apparatus;
a collating portion configured to collate a content of the preparation data preliminarily associated with the identification information read by the tray reading portion with a content of at least one of the medicine container, the syringe of the injector, the injection needle of the injector and the transfusion container loaded in the co-infusion apparatus; and
a discharge control portion configured to allow the medicine container, the syringe of the injector, the injection needle of the injector, or the transfusion container, whose collation result by the collating portion does not indicate matching, to be removed together with the tray from a predetermined discharge port.

16. The co-infusion apparatus according to claim 15 , further comprising:
an informing portion configured to, when identification information read by the tray reading portion from a subsequent
