Operation

The Intravenous Visual Mouse Tail Injection Fixator employs a press-and-push method to compress blood from the tail root veins toward the distal portion of the tail, ensuring angioplerosis of the vascular network in the latter half.
The engorged vascular diameter increases by approximately 40% compared to normal conditions. Combined with continuous arterial blood supply, the veins further expand, providing sufficient space for needle insertion.
The expanded vascular walls adhere tightly to the coccyx and skin, forming a fluid-filled space that prevents the needle tip from entering above the vessel or penetrating through the vessel wall.
This press-and-push method also stabilizes the tail, minimizing forward movement caused by animal discomfort. The device includes an adjustable tail support bracket to secure the injection site, ensuring stable and precise needle insertion.
The tail support bracket is equipped with yellow light illumination (light is absorbed by tail veins, causing them to appear dark). This clearly visualizes tail veins (particularly prominent in C57 mice), guiding needle depth, direction, and insertion length.
Operators can visually confirm whether the needle has entered the vessel, significantly improving accuracy compared to traditional methord.
The device supports single-operator use with pedal switch, achieving an average injection time of 15 seconds per mouse.
The working angle is adjustable to accommodate individual operating preferences.
With this device, high success rates are attainable across all mouse strains, including challenging cases, ensuring reliable vascular access with minimal training.
