1. A liquid delivery device for delivering a liquid drug to a patient or animal and adapted for facilitating drug analysis using NIR transmission spectrophotometry, the liquid delivery device comprising:
- an elongated reservoir comprising an elongated body having a first end and a second end adapted to contain liquid drug to be delivered, the reservoir having a luer connector disposed at the first end with a channel through which liquid drug may be dispensed,a liquid dispenser which causes a movement of the liquid drug from the reservoir to and through the channel in the luer connector,wherein the luer connector comprises first and second solid planar optical transparent sections arranged parallel on opposing sides of the channel, each transparent section being 0.8 to 1.2 mm thick and having predetermined optical and physical properties that allow electromagnetic radiation to pass through one of the transparent sections in a known manner into the interior of the channel and that allow such electromagnetic radiation affected by the liquid drug in the channel to pass through the other of the transparent sections as the affected electromagnetic radiation leaves the channel to facilitate analysis of he liquid drug in the channel using NIR transmission spectrophotometry,wherein the position of the transparent section allows contents of the channel to be analysed through the transparent sections using NIR transmission spectrophotometry when the liquid delivery device is docked end on.
