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.

Claims

1. A liquid delivery device adapted to deliver a liquid drug to a patient or animal comprising:

a reservoir adapted to contain liquid drug to be delivered, the reservoir having an outlet through which liquid drug may be dispensed,

a liquid dispenser with a longitudinal axis which causes movement of the liquid drug from the reservoir to and out of the outlet, the liquid dispenser comprising optically readable markings disposed at a plurality of positions along at least a portion of the longitudinal axis,

an optical reader comprising at least one optical detector arranged to detect the optically readable markings, each optical detector adapted to provide an output signal indicative of one or more detected optically readable markings, and

a processor coupled to receive the output signal and generate position data indicating a position of the liquid dispenser relative to the reservoir.

2. A liquid delivery device according to claim 1 wherein the processor generates quantity data indicating a quantity of liquid drug in the reservoir.

3. A liquid delivery device according to claim 1 wherein the optically readable markings comprise a plurality of indicia positioned in a sequence along at least a portion of the longitudinal axis of the liquid dispenser, and wherein the processor generates the position data by counting the number of indicia detected by the optical detector as the liquid dispenser is moved relative to the optical detector.

4. A liquid delivery device according to claim 3 wherein the optical reader comprises at least two optical detectors arranged to detect the indicia, wherein the optical detectors are positioned at a relative separation to provide quadrature encoding signals that can be used by the processor to generate the position data and direction data indicating the direction in which the liquid dispenser is moved relative to the optical detector.

5. A liquid delivery device according to claim 3 wherein the position data is indicative of the quantity of liquid within the reservoir.

6. A liquid delivery device according to claim 3 wherein the optical reader comprises a transmitter adapted to wirelessly transmit the quantity data or position data to a system.

7. A liquid delivery device according to claim 3 wherein the optical reader is detachable from the liquid delivery device.

8. A liquid delivery device according to claim 3 wherein the optical reader further comprises an energy storage device coupled to an inductive device, the inductive device adapted to inductively couple to an inductive recharging device to receive energy for recharging the energy storage device.

9. An optical reader adapted to couple to a liquid delivery device and generate position data indicative of the position of a liquid delivery means of the liquid delivery device, the optical reader comprising:

a coupling for attachment to a liquid delivery device,

at least one optical detector arranged to detect optically readable markings on a liquid delivery means, each optical reader adapted to provide an output signal indicative of one or more detected optically readable markings, and

a processor coupled to receive the output signal and generate position data indicating a position of the liquid dispenser relative to the reservoir.

10. An optical reader according to claim 9 wherein the processor generates quantity data indicating a quantity of the liquid drug in the reservoir.

11. An optical reader according to claim 9 wherein the optically readable markings comprise a plurality of indicia positioned in a sequence along at least a portion of a longitudinal axis of the liquid dispenser, and wherein the processor can generate the position data by counting the number of indicia detected by the optical detector as the liquid dispenser is moved relative to the optical detector.

12. An optical reader according to claim 9 wherein the optical reader comprises at least two optical detectors arranged to detect the indicia, wherein the optical detectors are positioned at a relative separation to provide quadrature encoding signals that can be used by the processor to generate the position data and direction data indicating the direction in which the liquid dispenser is moved relative to the optical detector.

13. An optical reader according to claim 9 wherein the position data is indicative of a quantity of liquid within the reservoir.

14. An optical reader according to claim 10 further comprising a transmitter adapted to wirelessly transmit the quantity data or position data to a system.

15. An optical reader according to claim 9 wherein the optical reader further comprises an energy storage device coupled to an inductive device, the inductive device adapted to inductively couple to an inductive recharging device to receive energy for recharging the energy storage device.
