Sampling probe, gripper and interface for laboratory sample management systems
First Claim
1. A sampling probe comprising a drive module having a reciprocating drive coupling, and a syringe module removably coupled coaxially to the drive module to allow for different syringe modules to be interchangeably coupled to the drive module, wherein the syringe module includes a plunger barrel, a plunger movable in the plunger barrel, and a plunger rod extending from an end of the plunger barrel for removable coupling to the drive coupling of the drive module for effecting common reciprocating movement of the plunger rod with the drive coupling, and the drive module and syringe module have cylindrical outer surfaces of the same outer diameter such that together the modules provide the probe with a substantially continuous cylindrical outer surface of uniform diameter;
- wherein the drive module and syringe module include a drive module housing and a syringe module housing, respectively; and
wherein the drive module housing houses a drive motor and a rotary-to-linear motion transfer device interposed between the drive motor and drive coupling.

Abstract
A self-contained sampling probe characterized by a drive module and a syringe module removably coupled coaxially to the drive module to allow for different syringe modules to be interchangeably coupled to the drive module. The coupling is effected by quick connect and disconnect devices, and the syringe module may carry an identifier. The probe is engageable by a gripper or insertable in an interface device, both of which provide for communication of the probe with other system components.

10. A sampling probe comprising a drive module and a syringe module removably coupled coaxially to the drive module to allow for different syringe modules to be interchangeably coupled to the drive module, wherein the drive module and syringe module include a drive module housing and a syringe module housing, respectively;
- wherein the drive module housing houses a drive motor and a rotary-to-linear motion transfer device, and the syringe module housing contains a plunger configured at one end for detachable coupling to the rotary-to-linear motion transfer device; and
wherein at least one of the transfer device and plunger includes a stem terminating at an enlarged head, and the other includes a coupling body having a side slot with a narrow portion extending from an end of the coupling body to a wider portion of the side slot, the narrow portion being sized to receive the stem but less than the width of the enlarged head, and the wider portion being sized to receive the enlarged head, whereby the plunger can be quickly and easily engaged and disengaged with respect to the transfer device.
- wherein the drive module housing houses a drive motor and a rotary-to-linear motion transfer device, and the syringe module housing contains a plunger configured at one end for detachable coupling to the rotary-to-linear motion transfer device; and
