The Advanced Bovine Tail Venipuncture Model was developed by Dr. McLean Gunderson in collaboration with Jesse Darley of the UW–Madison Design Hub. The model is composed of 3D-printed plastic components connected by elastic cord, creating a durable yet flexible representation of the bovine tail.
A silicone tube embedded within the framework functions as a synthetic coccygeal vein. When connected to a fluid bag, the model simulates a “live” venous system, allowing learners to practice intravenous medication administration and blood collection from the tail vein. The model supports repeated, low-stress, low-stakes practice with both positive and negative feedback, and is used to build technical skill and confidence in veterinary students, veterinary technicians, continuing education (CE) participants, and outreach settings as an alternative to working with live large-animal patients.
Designed for instructional versatility, the model is lightweight, water-resistant, and highly portable. It can be easily secured to fluid poles or other upright structures, allowing flexibility across teaching environments, and is used in conjunction with other developed models for jugular venipuncture, intramuscular injections, and related clinical skills.
By providing a realistic, repeatable simulation experience, the model reduces reliance on live animals during early skills acquisition, supporting animal welfare while improving learner preparedness and clinical outcomes for both students and cattle.
The components are highly durable while remaining modular, allowing for low-cost replacement of individual parts as needed. Externally sourced materials include silicone tubing, Luer-lock components, elastic cord, and the silicone-and-fabric skin covering. The model is easily manufactured and reproducible, supporting scalable use across educational programs.
