US 8,465,448 B2 · Devices for the administration of drugs and vaccines in the form of injectable needles

Abstract

The present disclosure refers to hand operated disposable devices for the administration of drugs, vaccines and other medicaments in the form of solid injectable needles. The devices incorporate mechanisms for the automatic retraction of the injection rod even when the user continues to exert pressure on the device. The devices can incorporate an injectable needle in a sheath or cartridge that facilitates its manufacture and manipulation. These injection devices can only be used once and their use results in a change of configuration that renders them non operational and prevents contact with parts that have been exposed to the patient's tissues.

Dependent claims

An injector device for the injection of a solid injectable needle containing a medicament into animal or human tissues, the injection device comprising:

an injection rod positioned and configured to inject the injectable needle into the tissues;
an actuator configured to undergo direct manual compression so as to drive the injection rod;
and
means for causing automatic retraction of the injection rod upon reaching a point of maximum penetration, even under continued compression on the actuator,
wherein the means for causing automatic retraction of the injection rod further comprises means for releasing a plunger from the actuator, rendering the injector device useless after one use.
