SINGLE USE INJECTION SYSTEM

摘要

The invention is a single use intradermal injection device capable of intradermal delivery an agent (e.g., vaccine, drug, medicament, etc.) in a controlled manner and without requiring specialized skill in administering delivery of such agent. The injection device is configured to be filled on-site and in the field with a microdose of an agent, while remaining sterile and preventing the potential for contamination during the filling process. The injection device is further configured to be rendered incapable of reuse following its delivery of the agent to a patient, thereby preventing reuse of the device and reducing the risk of the spreading blood-borne diseases through reuse.

主权项

1. A single use injection device comprising:
a needle for intradermal injection of a fluid agent into a patient; a base member for providing said fluid agent into said needle, said base member comprising:
a proximal end having an inlet port configured to receive said fluid agent from a source and a distal end having an outlet port coupled to said needle and configured to provide said fluid agent thereto;a channel providing a fluid pathway from said inlet port to said outlet port; anda one-way valve positioned within said fluid pathway of said channel, said one-way valve configured to limit fluid flow to an antegrade direction from said inlet port towards the outlet port; and a top member coupled to said base member and comprising a compressible reservoir member in fluid communication with said fluid pathway of said channel, said reservoir member having an interior volume configured to receive and store said fluid agent passing through said one-way valve and configured to expel said fluid agent into said fluid pathway and through said outlet port into said needle in response to a compression force applied thereto.
