Title:
METHODS FOR OPERATING A SYRINGE AND RELATED DOSE EXTRACTION AID
Document Type and Number:
WIPO Patent Application WO/2022/157169
Kind Code:
A3
Abstract:
The invention relates to a method of performing injections of a liquid substance and how to achieve a high dosing accuracy and low loss due to dead spaces, providing higher yield and more uniform dosing. When used with vaccination programs, the method reduce costs and increase availability of the vaccine by allowing more doses to be extracted from a vial. The invention suggests calibrating the scale of a syringe and how to virtually eliminate loss from dead spaces by use of a flushing fluid and how to introduce said flushing fluid in a syringe. The present invention also relates to a dose extraction aid for use in extracting a liquid from a vial, comprising: a base unit, a vial holder defining a vial axis, an extraction unit holder and a ventilation unit holder, wherein the vial axis is inclined in relation to a base surface of the base unit, the vial holder is configured for holding the vial in a position where an opening of the vial is further from the base surface than an exterior bottom surface of the vial. The invention further relates to a method for extracting a dose of a liquid from a vial using a syringe and a dose extraction aid.
