Embodiment Construction

[0168] For over a decade, the applicant of the present application has been engaged in the development, manufacture and sale of components of closed system liquid transfer devices designed to provide contamination-free transfer of hazardous drugs. These products are used to reconstitute powdered medications and transfer hazardous drugs in liquid form between vials, syringes and IV bags. The background section of this application describes some of the products developed and a robotic system utilizing them to automate the preparation of prescriptions. The present invention relies on the work done to date on components of closed systems to develop similar components for the preparation of prescriptions involving harmless drugs.

[0169] The drug is supplied in a bottle by the manufacturer as a liquid or powder. If in powder form, the drug must be reconstituted by adding an amount of liquid diluent to the inside of the bottle. In either case, preparation of the prescription invo...

Abstract

A robotic system and a vented vial adapter are presented herein, the robotic system configured to compound and prepare a drug including a harmless drug. The robot system comprises a laminar flow cabinet; and at least one robotic arm. The vented vial adapter is designed to connect a vial to another component of the drug transfer system. The adapter includes a hydrophobic filter that prevents the passage of liquid while allowing air to pass through the hydrophobic filter, and an air vent to the atmosphere. The vent hole is positioned above the filter, thereby equalizing the internal pressure while preventing the drug from contaminating the atmosphere.

Description

technical field [0001] The present invention relates to the field of fluid transfer devices. In particular, the present invention relates to components of an open liquid drug transfer system and the use of said components in an automated robotic system for the preparation of drugs and pharmaceuticals for administration to a patient. Background technique [0002] US 8,196,614 to the applicant of the present invention describes a closed system liquid transfer device designed to provide contamination-free transfer of hazardous drugs. Figures 1a and 1b are schematic cross-sectional views of a device 10 for transferring hazardous drugs without polluting the environment, according to an embodiment of the invention described in US 8,196,614. The main features of this device relevant to the present invention will be described here. Additional details can be found in the patents mentioned above. [0003] The proximal section of the device 10 is a syringe 12 adapted to withdraw a d...
