Abstract
An injector including at least one fluid reservoir having a needle, a surface attached to skin and coupled to the fluid reservoir by at least a first joint and a second joint at least a portion of one of the joints being slidable or having interlocking arms. At least a portion of a path of translation of a slidable portion of the first joint and a portion of a path of translation of the second joint are angled in respect to each another.
Claims18
A method of injection, comprising:
- rotating a needle connected to a fluid reservoir relative to a surface configured for attachment to skin about a first joint;
- concurrently moving the needle along a translational degree of freedom of each of the first joint and a second joint;
- and
- inserting at least a portion of the needle across a surface of skin;
- wherein the concurrently rotating and translating the needle converts a curvilinear travel path of the needle into at least a portion of the needle crossing the surface within less than 5 degrees deviated from a straight line.
