[Long-term infusion technique via tail vein in unrestrained rat. Technical short communication (author's transl)]

Abstract

A technique is described that allows tail vein infusion in the rat up to several weeks without the risk of pressure necrosis of the tail. By the aid of a simple metallic device the catheter is protected against damage by the animal. Since this armament is well tolerated and the mobility of the rat remains unimpaired, psychic stress is minimized.
