Abstract
A catheter hub assembly is disclosed wherein the assembly contains a membrane useful in preventing backflow of blood into the flash chamber. The hub assembly contains a membrane opener which operates upon the insertion of a luer locking mechanism into the catheter hub. This membrane opener allows flow of nutritional fluid into the body by causing the opening of the membrane during use of the catheter after removal of the catheter needle.
