A device that automatically performs injection in the
tail veins using a collaborative robot with AI camera.
Method of Use
Fixation of anesthetized rat/mouse
Imaging with Artificial Intelligence camera
(Application of vision machine learning algorithm)
Align with the tail vein location
and move to the robot arm
Needle detection and fine tuning
Tail vein injection
Green Line : Needle , Red Line : Tail vein
Injection of 50 μl of saline solution
Artificial Intelligence aligns tail vein and needle, and a collaborative robot
controlled by GUI in 0.01mm increments automatically injects drugs.
Tail vein recognition using vision machine learning
(A) Tail vein recognition. Rat tail(left), vein recognized as red line(right).
(B) Schematic of U-net image segmentation model.
Tail intravenous (I.v) injection of 8% Evans blue by automated administrator.
(A) Injection process images of success injection and failure injection.
White arrows indicate the Evans blue flowing the vein in success injection.
(B) Representative images of SD-
rats that received I.v injection, sho
wing blue coloration of their eyes,
ears, nose, and paws only followin
g success injection.
(C) Pre- and post-injection images of success and failure case.
