Filed:

Sep 28, 2007

Appl. No.:

11/863830

Inventors:

Otto Daniel DeRuntz - Dunstable MA, US
Kenneth Allen Focht - Needham MA, US
Alexander Thomas Jacobs - Somerville MA, US
Elizabeth Whitney Johansen - Allston MA, US
Jared Alden Jodson - Topsfield MA, US

Assignee:

Eli Lilly and Company - Indianapolis IN

International Classification:

A61M 5/00

US Classification:

604207, 604211, 604187

Abstract:

A medication dispensing apparatus that provides a mechanical advantage. During dose preparing, a nut rotating element () and a screw element () are in a first axial arrangement such that a screwing motion of the nut rotating element and screw element relative to the apparatus housing that moves the elements a first axial distance from a home position screws a nut () along a drive member threaded shaft () a second axial distance different than the first axial distance. During dose dispensing, the nut rotating element and the screw element are in a second axial arrangement, whereby a screwing motion of the screw element relative to the housing back toward the home position advances a plunger () in the distal direction to axially advance the nut and thereby the drive number and a fluid container piston to dispense medicine.

International Classification:

A61M 5/00
A61M 5/315

US Classification:

604110, 604187, 604218

Abstract:

A medication dispensing apparatus with a spring-driven locking feature includes a drive member movable in a distal direction within a housing, and a fluid container with a piston that is advanceable by the drive member () when such drive member is moved distally by a driving means. The apparatus includes a latching element () having a skid () that is slidable along a surface of the drive member as the drive member passes distally during advancement. The drive member is arranged with the skid so as to maintain a latching lip of the latching element against a spring force in a first position free of the driving means during dose preparing and injecting prior to a final dose administration. The skid-engaging surface shifts distally of the skid such that the skid passes beyond a proximal end of that surface upon administration of a final dose, whereby the latching lip is urged by the spring force from the first position to a second position to physically lock the driving means to prevent further dose preparing and injecting.

Appl. No.:

10/598989

Inventors:

Alexander Thomas Jacobs - Cambridge MA, US
Jared Alden Judson - Topsfield MA, US

Assignee:

Eli Lilly and Company - Indianapolis IN

International Classification:

A61M 5/315

US Classification:

604224

Abstract:

A medication dispensing apparatus having a gear set () to provide a mechanical advantage to the plunging of the apparatus plunger (). The gear set has a first pinion () in meshed engagement with a rack (91) of the plunger, and a second pinion () in meshed engagement with a rack () of a drive member () of the apparatus. The gear set operatively interconnects the plunger and the drive member such that after the plunger is moved relative to the housing () in proximal direction to prepare the apparatus for injection, the plunger, when distally moved, causes the drive member to advance in a distal direction to force medication through an outlet, typically provided with an injection needle (), at the distal end () of the apparatus. An opening () through one of the pinions accommodates the drive member to allow for a compact apparatus.
