Sampling probe, gripper and interface for laboratory sample management systems

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.

1 . A syringe module for a sampling probe comprising a barrel, end members at opposite ends of the barrel, a dispensing/aspirating lumen connected on one of the end members, and the other end member including a through hole for passage of the rod of a plunger disposed in the barrel for reciprocating movement, the plunger rod having at it distal end a coupler for quick connection to a coupling member of a drive module. 
     
     
         2 . A syringe module according to  claim 1 , wherein the coupler is an enlarged head on an end of the plunger rod. 
     
     
         3 . A syringe module according to  claim 2 , wherein the enlarged head is a ball for mating in a socket of a plunger drive member.
