A home-made low-cost hydraulic swivel and catheter assembly for blood pressure recording and drug infusion in freely moving mice.
We constructed a chassis that tightly fixes catheters for cannulation to the muscle. It can buffer pulling forces to avoid a mechanical tearing of the skin of mice as a result of movement. A simple hydraulic swivel was also made for blood pressure recording and drug infusion in freely moving mice.
