Appl. No.:

5/778727

Inventors:

Sheldon Kaplan - Potomac MD
Edward M. Curley - Washington DC
Gerlof Homan - Olivette MO

Assignee:

Survival Technology, Inc. - Bethesda MD

International Classification:

A61J 100

US Classification:

1282723

Abstract:

An additive adapter for use in conjunction with an injector wherein the injector includes a cylindrical body having a rearward open end and a forward end necked inwardly to form an annular lip. The forward end having a central opening of reduced diameter which is closed off by a sealing diaphragm. A plunger is sealingly and slidably fitted in the rearward portion of the body to form a medicament chamber between the sealing means and the plunger. A needle hub is affixed to the annular lip and carries a needle which is in fluid communication with the medicament chamber upon the opening of the sealing diaphragm. The additive adapter comprises a main body portion including a cylindrical skirt portion extending from the rearward end of the cylindrical sleeve. The skirt is sized to snugly engage and fit over the forward portion of the injector's cylindrical body. A cylindrical shield having a diameter larger than the cylindrical sleeve extends from the forward end thereof.

Abstract:

A package for enabling a user to mix a diluent with a hazardous material and then fill a syringe with the solution in such a way as to substantially prevent the hazardous material from entering the immediate atmospheric environment comprising a vial and a sealed bag enclosing the entire vial so as to provide exterior sealed containment for the vial in the event of unexpected failure of the vial container and elastomeric stopper assembly to sealingly contain the hazardous material. The vial is sealed within the bag so as to form a space exteriorly of the vial which is controlled by the bag and which is operable to receive any hazardous material in the form of aerosol or droplets that may pass outwardly through the elastomeric stopper assembly as a result of the withdrawal of the syringe needle therefrom and the increased interior gas pressure created within the vial container by the injection of diluent therein. The controlled space has a volume sufficient to enable the pressure therein to remain near atmospheric pressure in the event of the escape of gas pressure from the vial container as aforesaid so that there is substantially no tendency for gas therein to cause hazardous material which may have passed into the controlled space to escape to the atmosphere when the needle is removed from the access septum assembly of the bag.
