Abstract

In an embodiment, the present specification is an alarm/warning system for notifying a user cleaning an endoscope that the main connector/electrical connector of endoscope has not been covered by a connector cover. The warning system indicates an absence of a connector cover cup when the connector of the endoscope is not connected to a main control unit.

Claims

1. An endoscope assembly, comprising:

a handle;

a connector for connecting the endoscope assembly to an endoscope control unit, the connector including a fixed end fixed to the handle, and a free end opposite the fixed end, the free end being configured to be received in and entirely withdrawn from the endoscope control unit; and

a warning system for indicating an absence of a connector cover, the connector cover being adapted to cover said free end of the connector, when said connector is not connected to the endoscope control unit, the warning system comprising;

an alarm unit configured to emit at least one of light and sound from the free end of the connector,

a power source in the free end of the connector for powering the alarm unit, and

a detection system in the free end of the connector for detecting said absence of the connector cover on top of said free end of the connector, and activating the alarm unit if the connector cover is absent from said free end of the connector, wherein the alarm unit, power source, and detection system are positioned within the free end of the connector.

2. The endoscope assembly as claimed in claim 1 wherein the alarm unit comprises a light emitting diode.

3. The endoscope assembly as claimed in claim 1 wherein the alarm unit comprises a sound producing speaker.

4. The endoscope assembly as claimed in claim 1 wherein the power supply for powering the alarm unit comprises a high capacitance capacitor.

5. The endoscope assembly as claimed in claim 1 wherein the power supply for powering the alarm unit comprises an electrical accumulator.

6. The endoscope assembly as claimed in claim 1 wherein the power source for powering the alarm unit is charged when the connector is connected to the control unit.

7. The endoscope assembly as claimed in claim 1 wherein the detection system comprises a micro-switch for detecting the absence of the connector cover.

8. The endoscope as assembly claimed in claim 1 wherein the detection system comprises a reed contact with magnetic system for detecting the absence of the connector cover.

9. The endoscope assembly as claimed in claim 1 wherein the detection system comprises a photodiode or phototransistor for detecting the absence of the connector cover.

10. The endoscope assembly as claimed in claim 9, further comprising a comparator to compare a signal generated by the photodiode with a threshold signal to estimate a presence or the absence of said connector cover.

11. The endoscope assembly as claimed in claim 1 wherein the detection system comprises an optocoupler for detecting the absence of the connector cover.

12. An endoscope system, comprising:

a control unit;

an endoscope assembly;

a connector for connecting the endoscope assembly to the control unit, the connector including a cable, wherein the cable has a fixed end on the endoscope assembly, and a free end opposite the fixed end, wherein the free end of the connector is configured to be received by the control unit to couple the endoscope assembly to the control unit, and withdrawn from the control unit;

a connector cover adapted to cover the free end of the connector, thereby blocking receipt of the free end of the connector by the control unit;

a detection system, positioned within said free end of the connector, to generate a signal indicative of a presence or absence of the connector cover on said free end of the connector while said free end of the connector is not received by the control unit; and

a notification system, positioned within said free end of the connector, to receive and process said signal generated by the detection system and, based on said signal, activate or deactivate an alarm to communicate a presence or absence of said connector cover on the free end of the connector.

13. The endoscope system as claimed in claim 12 wherein said notification system comprises a microcontroller or a processing unit to analyze said signal.

14. The endoscope system as claimed in claim 12 wherein said notification system comprises at least one of a light based alarm unit or a sound based alarm unit.

15. The endoscope system as claimed in claim 12 wherein said detection system comprises at least one of a micro switch or a reed contact with a magnetic system.

16. The endoscope system as claimed in claim 12 wherein said detection system comprises a photodiode.

17. The endoscope system as claimed in claim 16, further comprising a comparator to compare a signal generated by the photodiode with a threshold signal to estimate a presence or absence of said connector cover.

18. The endoscope system as claimed in claim 12 wherein said detection system comprises an optocoupler.

19. The endoscope system as claimed in claim 12 further comprising a power source for powering said alarm unit.

20. The endoscope system as claimed in claim 19 wherein said power source is at least one of a capacitor or an electrical accumulator.

21. The endoscope system as claimed in claim 19, wherein the power source used for powering the alarm unit is adapted to be charged when said free end of the connector is connected to the control unit.

22. An endoscope system comprising:

a connector for connecting an endoscope assembly to a main control unit of endoscope, the connector including a fixed end at the endoscope assembly, and a free end opposite the fixed end;

a connector cover to encompass at least a portion of said free end of the connector when said free end of the connector is not connected to said main control unit, the connector cover blocking connection of the free end of the connector to the main control unit when the connector cover encompasses at least the portion of the free end of the connector;

an alarm system, positioned within said free end of the connector, to indicate an absence of said connector cover over said free end of the connector; and

the main control unit comprising a regulator to control said alarm system when said free end of the connector is connected with the main control unit.

23. The endoscope system as claimed in claim 22, wherein said connector cover comprises a micro switch to detect a presence of the connector cover when said free end of the connector is not connected to said main control unit.

24. The endoscope system as claimed in claim 22, wherein said connector cover comprises a reed contact with a magnetic switch to detect a presence of the connector cover when said free end of the connector is not connected to said main control unit.

25. The endoscope system as claimed in claim 24, wherein said connector cover comprises a magnet to regulate a function of said reed contact.

26. The endoscope system as claimed in claim 22, wherein said connector cover comprises a photo sensing device to detect a presence of the connector cover when said free end of the connector is not connected to said main control unit.

27. The endoscope system as claimed in claim 22, wherein said connector cover comprises an optocoupler to detect a presence of the connector cover when said free end of the connector is not connected to said main control unit.

28. The endoscope system as claimed in claim 22, wherein said alarm system comprises at least one of an acoustic indicator or a visual indicator.

29. The endoscope system as claimed in claim 22, wherein said connector comprises at least one of a power supply module to provide a power source for at least a portion of the alarm system, a charger, or a power control unit to regulate a power supply module.

30. The endoscope system as claimed in claim 29, wherein said main control unit provides power to charge said power supply module when said main control unit is connected to said free end of the connector.
