Abstract: In the inventive method for the sanitary rinsing of an animal, an assembly line is provided which includes a plurality of shackles. Each shackle includes an inventive tag which includes a machine readable unique shackle number. Once an animal is stunned and attached to a shackle the animal is moved to a weighing station, which is equipped with a tag reader, weighs the animal and transmits the weight and shackle number to a computer where the data is recorded in a database. The animal is then bled and moved to a rinsing station, which is equipped with a tag reader which reads the shackle number. The system then looks up the weight of the animal to be rinsed at that particular rinsing station and calculates the amount of solution to inject into the circulatory system of the animal.

Abstract: The present invention relates to a secured sanitary catheter for administration of treatment solution into animals comprising a catheter body with a longitudinal bore and a sanitary vascular securing device attached to the catheter body. The catheter body has a proximal end and a distal end, with the longitudinal bore terminating in an opening at the distal end of the catheter body, for delivery of treatment solution into a vessel of an animal. The sanitary vascular securing device contains a plurality of slots for mechanically and frictionally engaging the vessel at two or more points. The present invention further relates to a method for using the secured sanitary catheter of the present invention.
