Abstract

A device for the introduction of liquid medication into a flexible bag for the administration of intravenous solutions. The device comprises an elongated generally cylindrical hollow tubular member having an open end and a closed end, a boss extending from the closed end, carried by the boss a cannula having a sharpened outer end, and a rigid sheath surrounding the cannula and carried by the boss. The sheath serves to limit the advancement of the cannula into an orifice having a diameter greater than that of said cannula. A thrust portion is provided within the tubular member and a fluid passage extends longitudinally through the center of the thrust portion. The lower end of the fluid passage communicates with the upper end of the cannula. A cylindrical vial having a resilient stopper in its open end seals on the inside walls of the vial. There are threads on the thrust portion and cooperating threads on the stopper adapted to be interlocked, whereby the plug can be interlocked with the thrust portion.

Claims

1. The combination of a flexible bag for intravenous solution, extending from the top of said bag, an additive-receiving flexible tube-like orifice and an outlet adapted to lead to an intravenous solution set, and a device for the introduction of liquid medication into said flexible bag comprising an elongated generally cylindrical hollow tubular member having an open end and a closed end, a boss extending froM said closed end, carried by the boss a cannula having a sharpened outer end, a rigid cylindrical sheath of fixed length surrounding said cannula and affixed to said boss, said sharpened outer end extending slightly beyond the free end of said sheath, said orifice having a diameter greater than that of said cannula, said sharpened outer end being received in said flexible tube-like orifice and said sheath engaging said orifice to limit the advancement of said cannula into the orifice;

within said tubular member, a thrust portion, a fluid passage extending longitudinally through the center of said thrust portion, the lower end of said fluid passage communicating with the upper end of said cannula, a cylindrical vial having a resilient stopper in its open end sealing on the inside walls of said vial, interlocking means on said thrust portion and cooperating interlocking means on said stopper, whereby upon interlocking of said plug with said thrust portion said vial is first held in an assembled but non-operating position and upon further interlocking of said plug with said cylindrical member, said plug is adapted to be pierced by said fluid passage and said fluid passage communicated with said vial without the application of substantial axial pressure on said plug and said plug is locked securely to said cylindrical member to permit aspiration upon withdrawal of said vial or to permit expulsion of the contents of said vial upon exertion of pressure on said vial.

2. The combination of claim 1 wherein the sheath has two portions of different diameter, the outer portion having a diameter greater than the outside diameter of said orifice and the inner portion having a diameter less than the outside diameter of said orifice whereby an annular shoulder is provided at the junction of said portions which abuts the outer end of said orifice, said orifice having a lateral imperforate diaphragm which is pierced by said sharpened outer end when said shoulder and outer end of said orifice are in contact.
