Syringe and Optical Reader for Syringe

Abstract

The present invention relates to a syringe ( 1 ) for use in spectroscopy to identify drugs within the syringe ( 8 ). The syringe comprises a optical window section ( 8 ) either integral with or attached to the syringe ( 1 ). The optical window section ( 8 ) has predetermined physical and optical properties that allows radiation to pass through in a known manner to facilitate spectroscopy.

1 . A liquid delivery device adapted to deliver a liquid drug to a patient or animal, the device comprising:
 a reservoir adapted to contain the liquid drug to be delivered, the reservoir having an outlet through which the liquid drug may be dispensed,   a liquid dispenser that causes a movement of the liquid drug from the reservoir to and out of the outlet, and   an optical window section, for liquid drug, having predetermined optical and physical properties that allows radiation to pass therethrough in a known manner into an interior of the optical window section, and that allows radiation affected by a content of the reservoir to pass through as the affected radiation leaves the interior of the window,   wherein the optical window section:
 is attachable to the reservoir such that the interior of the optical window section is in fluid communication with the reservoir via the outlet, such that liquid drug within the reservoir can be expelled into the interior of the optical window section, 
   comprises at least two parallel planar panels that are at least partially transparent to radiation and are configured to dock in the recess of a holder to enable analysis of liquid drug therein, and
 comprises an outlet through which expelled liquid drug can escape. 
   
     
     
         2 . A liquid delivery device according to  claim 1  wherein the device is a syringe. 
     
     
         3 . A liquid delivery device according to  claim 2  wherein the device is an IV administration set. 
     
     
         4 . An IV administration set comprising:
 a reservoir adapted to contain the liquid drug to be delivered, the reservoir having an outlet through which the liquid drug may be dispensed, and   an optical window section, for liquid drug, having predetermined optical and physical properties that allows radiation to pass therethrough in a known manner into an interior of the optical window section, and that allows radiation affected by a content of the reservoir to pass through as the affected radiation leaves the interior of the window,   wherein the optical window section:
 is attachable to the IV administration set such that the interior of the optical window section is in fluid communication with the reservoir via the outlet, such that liquid drug within the reservoir can be expelled into the interior of the optical window section, 
   comprises at least two parallel planar panels that are at least partially transparent to radiation and configured to dock in the recess of a holder to enable analysis of liquid drug therein, and
 comprises an outlet through which expelled drug can escape.
