First Claim
1. A dispensing device for contamination-free administration of a drug provided in a drug container with a seal, the dispensing device comprising:
- at least one coupling member for establishing a non-detachable connection with the drug container, said coupling member including an insertion pin for penetrating the seal of the drug container and at least one barb member for engaging the drug container to establish said non-detachable connection;
a flexible container fillable with a gas;
a first conduit having a first stop valve which is openable and closeable, said first conduit connecting said coupling member with said flexible container to permit passage of the drug between said flexible container and the drug container; and
a second conduit having a second stop valve which is openable and closeable, said second conduit communicating with said flexible container for operation as an outlet.

Abstract
A one-piece dispensing device for the contamination-free administration of medicaments (cytostatica) is particularly suitable for use in ambulant treatment. The invention provides a connector for connecting medicament (cytostatica) containers to instruments by which the medicaments are administered. The connector is designed to prevent, without a complex apparatus, contamination of the surroundings during connection of the container and until its disposal. The dispensing device has at least one coupling member to create a non-releasable connection with a medicaments container. The coupling member has an insertion pin and barbed surfaces to accommodate the medicaments container. The coupling member is non-releasably connected via a tube to a flexible container which is to be filled with gas. The flexible container is non-releasably connected to a further tube outlet and a mechanically actuated stop valve is incorporated in each of the connecting tubes.
