Abstract
Abstract The following specification sets forth a parenteral nutrition trainer. The trainer specifically incorporates a water and stain resistant chest shield with adjustable straps. A storage pouch is fitted to the underside of the chest shield. The shield is formed in a bib-like manner in conjunction with adjustable straps. A training catheter is affixed to the chest shield to simulate an actual implanted catheter. The catheter exits the chest shield in a location where it would normally be used. The catheter is capped with a screw fitting closure that can be used in conjunction with a syringe for training purposes. The catheter extends a distance behind the shield to a plastic fluid receptacle. When not in use, the catheter tubing with its fluid receptacle can be coiled and placed in a storage pouch behind the shield or bib.
