Description

Technical Field

[0001] The utility model belongs to the technical field related to the application of infusion bottle robots, and in particular relates to a puncture needle protective cap detection device. Background Art

[0002] During the research and development of a medical intelligent infusion bottle switching robot, it was found that the puncture part of the infusion set is the part that contacts the infusion liquid and conducts the infusion channel. It is the part that contacts the infusion liquid both inside and outside the infusion set. Therefore, the puncture part must be protected by the puncture cap and not be disturbed or contaminated by factors such as air.

[0003] To maximize the protection of the puncture needle under the protective cap and minimize its exposure to air, the operator removes the protective cap during the infusion robot's grasping procedure after the puncture needle is loaded into the robot's arm and before the operator determines the next step, "opening the infusion channel." This step often results in medical personnel forgetting to remove the puncture needle cap. The robot fails to detect that the cap is not removed, and the system mistakenly executes the "insert the puncture needle into the infusion bottle to open the infusion channel" procedure, mistakenly inserting the puncture needle and the protective cap into the infusion bottle. This results in the infusion fluid coming into contact with the protective cap, which, unprotected from air, poses a risk of contamination. This not only fails to open the infusion channel, but also causes the infusion fluid to come into contact with the protective outer surface of the puncture needle, becoming contaminated and wasted, significantly increasing the workload for correcting this error. To address this problem, a puncture needle protective cap detection device has been developed. Utility Model Content

[0004] In view of the above problems, the present invention provides a trocar needle protective cap detection device for solving the technical problem that the infusion bottle robot cannot detect that the trocar protective cap has not been removed.

[0010] As a further improvement of the above-mentioned scheme, the image recognition detection mechanism further includes a background device for ensuring the accuracy of the camera shooting, and the object of the shooting is only the puncture device and the protective cap.

[0013] As a further improvement of the above-mentioned scheme, when the control unit detects that the protective cap on the puncture device is not removed, the control unit communicates with the actuator of the infusion robot through the control signal to prevent the puncture device from being inserted into the infusion container.
