Title:
SELF-CONTAINED SYRINGE FOR DISSOLUTION AND ADMINISTRATION OF DRUGS
Document Type and Number:
WIPO Patent Application WO/2018/085318
Kind Code:
A3
Abstract:
The invention provides a mixing syringe adapted for the storage of a two- component medicament in unmixed form. One of the components is a liquid, which is maintained in a separate, collapsible compartment until just prior to administration, while the other component, which may be solid or liquid, is stored within the syringe body. The act of partially withdrawing the plunger from the syringe creates a partial vacuum within the syringe body, and atmospheric pressure forces the liquid from the collapsible compartment through a one-way valve and into the syringe body. The combined medicament is then injected by use of the syringe in the usual manner.
