Benefits of technology

[0016]Desirable nostril guides provide a distal portion having a shape with an increasing cross-section size corresponding to increased insertion depth, whereby to adapt to a variety of nostril sizes, and to form a brace against nostril structure operable to maintain an orientation of the nozzle while operating the syringe. Workable nostril guides can be arranged to form a substantially bullet shape. One preferred guide is arranged as a conical plug with a diameter ranging between about 0.2 inches and about 0.8 inches.

Problems solved by technology

While operable, Ogle's device suffers from the requirement that a user must make manual valve adjustments to load and discharge a syringe.

Embodiment Construction

[0030]A currently preferred embodiment of the invention, indicated generally at 200, is illustrated in FIG. 2. The vial multi-access adapter 200 includes a socket 120 carrying a spike 133 and a plurality of cantilevered legs 137. Legs 137 include gripping structure 139 adapted to hold a vial to help maintain its reception on a spike 133. While the plurality of legs 137 are illustrated in the FIGs. as forming a substantially complete circle, even a single opposed pair of legs 137 can be operable as gripping structure. A valve 204, operable as a double check valve, is attached in fluid communication with the spike 133. A first end of valve 204 carries connection structure, generally indicated at 142, adapted for attachment to a syringe. A second end of valve 204 carries a surface 144 that typically is adapted to form a conventional slip fit with the luer of a needle, or other discharge device.

[0031]When adapter 200 is mated to a vial, fluid from the vial may be suctioned by an attache...

Abstract

A multi-access adapter operable to dispense doses of a medicament in succession from a bulk container, such as a vial. A preferred adapter may be used alone, or in combination with various discharge devices. A first preferred combination includes the adapter paired with a needle for injection of the medicament into one or more patients. A second preferred combination includes an atomizing nozzle affixed to the adapter and arranged for discharge of the medicament therethrough. Sometimes the atomizing nozzle carries a nostril guide structure that can be absorbent and may operate as a splash guard.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 10 / 737,656, filed Dec. 16, 2003, pending, the disclosure of which is hereby incorporated herein by this reference in its entirety.TECHNICAL FIELD[0002]The invention relates to devices for extracting a dose of a fluid from a sealed fluid container. The invention finds particular application in the medical field, providing multiple-dose extraction from vials or ampules, by incorporating a syringe as a cyclical pump.BACKGROUND[0003]Several devices have been developed to facilitate transfer of a dose of a liquid from a bulk container. In the medical field, certain of such devices may be used to transfer a dose of a medicament from a vial, or a bulk container of medicament, to a syringe for injection or administration of the dose to a patient. In some situations, it is desirable to transfer more than one dose of medicament from the container in rapid succession. Ogle, in U.S. ...
