Bulk compounder manifold
First Claim
1. A manifold for receiving fluid tubes in a bulk compounder, said manifold comprising:
- a plurality of inlets, each inlet defining an opening to a respective fluid passageway, each said passageway containing a check valve;
a common flow channel in fluid communication with each said passageway;
an outlet in fluid communication with said common flow channel, said outlet comprising an outlet port having a self-sealing membrane adapted to be penetrated by a cannula; and
an inlet port which is coaxial with said outlet, said coaxial inlet port containing a check-valve.

Abstract
The present invention provides a manifold for receiving fluid tubes in a bulk compounder. In its simplest form, the manifold includes a plurality of inlets, each inlet defining an opening to a respective fluid passageway, and each passageway contains a check-valve. Included in this manifold is an outlet in fluid communication with the fluid passageways and an inlet port which is coaxial with the outlet. The coaxial inlet port contains a check-valve. Included as a part of the present invention is a cannula adapted for use with the manifold of the present invention, tube sets for use with the manifold of the present invention, and a method of minimizing error in filling a bag using a manifold in accordance with the present invention.

14. A method of minimizing error in the filling of a product bag in a bulk compounding system, said method comprising the steps of:
-
providing a manifold with a minimum common volume to minimize residual holding of any one ingredient solution, the manifold comprising a plurality of inlets, each inlet defining an opening to a respective fluid passageway containing a check-valve, a common flow channel in fluid communication with each said passageway, and an outlet in fluid communication with said common flow channel, said outlet comprising an outlet port having a self-sealing membrane adapted to be penetrated by a cannula; and passing individual ingredient solutions through the manifold to fill a product bag; whereby error is reduced because of the minimization of the manifold common volume step.
