Abstract

Disclosed are systems and methods for aseptically filling pharmaceutical containers with a pharmaceutical substance and then lyophilizing it. In one general aspect, the system and method can employ a lyophilizer loader subsystem having an interior chamber in communication with an interior chamber of a lyophilizer subsystem via a portal with a sealable door, with the collective interior being aseptically sealable. An articulated robotic arm can be employed to batch transfer to the lyophilizer subsystem container nests bearing the pharmaceutical containers. In one embodiment, the nests may be transferred serially to the loader subsystem, with the articulated robotic arm being configured to transfer the nests of containers in batches to the lyophilizer subsystem. The articulated robotic arm can also be configured to be used to move batches of nests within the lyophilizer subsystem. One implementation includes two articulated arms and a joint rotary wrist driven by two rotary shoulders.

First claim

What is claimed is:

1. An integrated pharmaceutical processing system, comprising:
an actuator assembly including:
a housing having first and second shaft openings;
at least one rotary actuator held in the housing;

a first output shaft that passes through the first shaft opening in the housing, has a first end responsive to the at least one rotary actuator inside the housing, and has a second end outside the housing;
a second output shaft located proximate the first output shaft, wherein the second output shaft passes through the second shaft opening in the housing, has a first end responsive to the at least one rotary actuator inside the housing, and has a second end outside the housing;
a first upper arm having a first end connected to the second end of the first output shaft and a having a second end so that it is at least generally perpendicular to an axis of rotation of the first output shaft;
a second upper arm having a first end connected to the second end of the second output shaft and having a second end so that it is at least generally perpendicular to an axis of rotation of the second output shaft;
a first forearm having a first end and a second end;
a second forearm having a first end and a second end;
a first articulation between the second end of the first upper arm and the first end of the first forearm;
a second articulation between the second end of the second upper arm and the first end of the second forearm;
a wrist member including:
an articulation mount having an axis of rotation;
at least one nest support structure to support a multi-container nest on one side of the axis of rotation of the articulation mount;
a pushing surface located opposite the axis of rotation of the articulation mount from the nest support structure and is at least generally parallel to the axis of rotation of the articulation mount;
a third articulation between the second end of the first forearm and the second end of the second forearm, wherein the axes of rotation of the first and second output shafts, and the axes of the first, second, and third articulations are at least generally parallel, and
a rotary wrist actuator between the third articulation and the wrist member articulation mount.

2. The apparatus of claim 1 wherein the housing, housing openings, wrist actuator, and the first, second, and third articulations are all sealed.

3. The apparatus of claim 1 wherein the nest support structure is a multi-nest support mechanism of support structures that are each constructed to support one of a plurality of multi-container nests.

4. The apparatus of claim 1 wherein the integrated pharmaceutical processing system is a lyophilizer loading system.

5. The apparatus of claim 1 wherein the first and second forearms are offset with respect to each other in the direction of the axes of rotation to allow them to pass next to each other and above the first and second output shafts.

6. The apparatus of claim 1 further including a lifting actuator operatively connected to the first and second output shafts to lift the nests during transfers.
