Abstract

A bandolier of syringes for use in an automated syringe handling system is provided. The automated syringe handling system generally receives syringes and fills the syringe with a substance, such as a medicament. In one exemplary embodiment, the syringe handling system is a system that disperses one or more medicaments into the syringes in an automated manner. The bandolier includes a web, e.g., a strip of transparent material partially encapsulating bodies of syringes that are bound to the web at a prescribed interval. The bandolier includes a feature disposed within the prescribed interval and between the syringes with the feature being different from the surrounding web.

Claims

1. A bandolier of syringes for an automated syringe handling system, the bandolier comprising:

a web;

a multiplicity of syringes bound to the web at a prescribed interval;

a control feature disposed within the prescribed interval and between the syringes, the control feature being different from the surrounding web, wherein the control feature is an aperture formed in the web.

2. The bandolier of claim 1, wherein the web is formed of at least one plastic sheet.

3. The bandolier of claim 1, wherein the web comprises first and second striplayers, the multiplicity of syringes being disposed between the first and second strip layers with the prescribed interval being defined by the first and second strip layers disposed between adjacent syringes.

4. The bandolier of claim 3, wherein the first and second strip layers are in intimate contact the multiplicity of syringes and the first and second strip layers are sealed against one another in the prescribed interval.

5. The bandolier of claim 1, wherein there is a correlation between a location of the control feature in the prescribed interval and a type of syringe that is bound to the web.

6. A bandolier of syringes for an automated syringe handling system, the bandolier comprising:

a web;

a multiplicity of syringes bound to the web at a prescribed interval;

a control feature disposed within the prescribed interval and between the syringes, the control feature being different from the surrounding web, wherein the control feature is an optical feature formed on a surface of the web.

7. The bandolier of claim 6, wherein the control feature has a first reflective characteristic and the web surrounding the feature has a different second reflective characteristic.

8. A control system for an automated syringe handling system, the control system comprising:

an indexer configured to advance a syringe through the automated syringe handling system;

a bandolier of syringes supplying syringes to the indexer, the bandolier including;

a web, a multiplicity of syringes bound to the web at a prescribed interval, and a control feature disposed within the prescribed interval and between the syringes, the control feature being different from the surrounding web; and

a detection system including a detector positioned to detect the control feature on the bandolier and perform a prescribed operation in response to the detection or non-detection of the control feature, wherein the control feature is an aperture formed in the prescribed interval.

9. The control system of claim 8, wherein the detector includes a nozzle discharging a laminar flowing fluid and a sensor for detecting the laminar flowing fluid, the nozzle being disposed on one side of the web and the sensor being disposed on an opposite side of the web, the nozzle, aperture and sensor all being in registration under select conditions as the bandolier is advanced.

10. The control system of claim 9, wherein the select conditions are when the web is in proper alignment and the multiplicity of syringes being used are of a type for use with the automated syringe handling system.

11. The control system of claim 9, wherein the fluid is air and the sensor is a pressure sensor for detecting the discharged air when the feature is in registration with the nozzle such that the laminar air flow passes through the feature and contacts the pressure sensor.

12. The control system of claim 8, wherein the detector includes a thermal device for generating heat and a thermal sensor, the thermal device being disposed on one side of the web and the thermal sensor being disposed on an opposite side of the web, the aperture and detector being in registration under select conditions as the bandolier is advanced.

13. The control system of claim 12, wherein the select conditions are when the web is in proper alignment and the multiplicity of syringes being used are of a type for use with the automated syringe handling system.

14. The control system of claim 8, further including a controller for advancing the bandolier, the controller being in communication with the detection system and the detection system being configured such that the detector sends a first signal to the controller upon sensing the control feature.

15. The control system of claim 14, wherein the first signal directs the controller to advance the bandolier a prescribed distance.

16. The control system of claim 8, wherein the detector is an optical detector arranged in cooperation with a light source and the control feature is an optical feature, the detector and light source detecting the optical feature of the bandolier when the optical feature is in proper registration therewith, the bandolier only being advanced if the optical feature is detected by the optical detector as the bandolier is advanced a predetermined distance.

17. The control system of claim 8, wherein the detector detects waves selected from the group consisting of ultrasonic waves, optical waves, and thermal energy waves, the detector further including logic that permits the one or more characteristics of the waves to be analyzed.

18. The control system of claim 17, wherein the one or more characteristics include an amplitude of the waves.

19. The control system of claim 18, further including a controller for advancing the bandolier in the automated syringe handling system, the controller being in communication with the detection system, the bandolier being advanced only if the detection system detects the control feature within prescribed criteria.

20. The control system of claim 19, wherein the prescribed criteria is one of a predetermined time period and a predetermined distance that the bandolier has been advanced.

21. The control system of claim 8, wherein the detector discharges a laminar air flow through a nozzle that is in selective alignment with the aperture, a sensor disposed on a side of the web opposite where the nozzle is disposed, the controller responding to a pressure of the laminar air flow through the aperture or to a logical waveform resulting from the timing of the first signals relative to periods where the first signals are not received.

22. The control system of claim 14, wherein the distance between control features corresponds to the distance that the bandolier is advanced upon receiving the first signal.

23. The control system of claim 14, wherein the controller advances the bandolier only a predetermined distance without detecting one control feature.

24. A control system for an automated syringe handling system, the control system comprising:

an indexer configured to advance a syringe through the automated syringe handling system;

a bandolier of syringes supplying syringes to the indexer, the bandolier including;

a web, a multiplicity of syringes bound to the web at a prescribed interval, and a control feature disposed within the prescribed interval and between the syringes, the control feature being different from the surrounding web; and

a detection system including a detector positioned to detect the control feature on the bandolier and perform a prescribed operation in response to the detection or non-detection of the control feature, wherein the detection system is connected to a communications network to permit the detection system to be remotely controlled.

25. The control system of claim 24, wherein the communications network is a wireless communications network.
