Abstract

An imaging system comprising a disposable part (1) comprising a camera device (5), said disposable part arranged to be suitable for allowing said camera device to be inserted into a body cavity, a reusable control module (8) in communication with said disposable part, said reusable control module comprising a display which displays image signals from the camera device in the disposable part, a timing device which generates time of use data of the disposable part, said time of use data representing the amount of time which the disposable part is in use, and said imaging system being arranged to prevent use of the disposable part if the time of use of the disposable part reaches a predefined level. The disposable part further comprises a non-volatile memory component which stores time of use data generated by said timing device and in that said reusable control module is arranged to continuously monitor the time of use data stored in the non-volatile memory component of the disposable part and to stop displaying image signals from the camera in the disposable part when the time of use data stored in the non-volatile memory component reaches said predefined level. In this way an imaging system is provided which is able to prevent using a disposable part which has been used on one patient on another patient.

Claims

1. An imaging system comprising

a. a disposable part (1) comprising a camera device (5), said disposable part arranged to be suitable for allowing said camera device to be inserted into a body cavity,

b. a reusable control module (8) in communication with said disposable part, said reusable control module comprising a display which displays image signals from the camera device in the disposable part,

c. a timing device which generates time of use data of the disposable part, said time of use data representing the amount of time which the disposable part is in use, and

d. said imaging system being arranged to prevent use of the disposable part if the time of use of the disposable part reaches a predefined level,

e. and said disposable part further comprises a non-volatile memory component which stores time of use data generated by said timing device, characterized

f. in that said reusable control module is arranged to continuously monitor the time of use data stored in the non-volatile memory component of the disposable part and to stop displaying image signals from the camera in the disposable part, and/or cuts power to the disposable part when the time of use data stored in the non-volatile memory component reaches said predefined level.

2. An imaging system according to claim 1, characterized in that said control module (8) is arranged to provide a visual or an audible warning to the user of the disposable part (1) a predefined amount of time before the control module stops displaying image signals from the camera device (5) in the disposable part.

3. An imaging system according to claim 1 or 2, characterized in that said control module (8) is arranged to provide information to the user of the disposable part (1), said information comprising the time of use data stored in the non-volatile memory component of the disposable part.

4. An imaging system according to any one of claims 1 to 3, characterized in that said control module (8) is arranged to provide information to the user of the disposable part (1), said information representing the time remaining before the control module stops displaying image signals from the camera in the disposable part.

5. An imaging system according to any one of claims 1-4, characterized in that said timing device furthermore generates information relating to the time at and/or the date on which the disposable part (1) was first used, said information being stored in the non-volatile memory component of the disposable device.

6. An imaging system according to claim 5, characterized in that said control module (8) is arranged

a. to continuously monitor the information stored in the non-volatile memory component of the disposable part (1) relating to the time and/or date on which the disposable part was first used, and

b. to stop displaying image signals from the camera in the disposable part when the time elapsed since the disposable part was first used reaches a certain predefined level.

7. An imaging system according to any one of claims 1 to 6, characterized in that said disposable part (1) comprises the timing device.

8. An imaging system according to claim 5 or 6 and claim 7, characterized in that said timing device comprises two timers, a first timer which continuously updates the time of use data stored in the non-volatile memory component of the disposable part (1) and, a second timer which keeps track of the time elapsed since the disposable part was first used and stores the time elapsed since first use on the non-volatile memory component of the disposable device.

9. An imaging system according to claim 8, characterized in that said disposable part (1) further comprises a power source which is used to provide power to the second timer.

10. An imaging system according to claim 9, characterized in that said power source is a super capacitor which is charged when the disposable part (1) is connected to the control module (2).

11. An imaging system according to any one of claims 1-6, characterized in that said control module (8) comprises the timing device.

12. An imaging system according to claims 5 and 11 or claims 6 and 11, characterized in that said timing device comprises a real time clock which generates time and/or date information and where the timing device is arranged to write the time and/or date information of the first use of the disposable part (1) to the non-volatile memory of the disposable part when the disposable part is first used and where the control module (8) continuously compares the current time and date information generated by the real time clock and the time and date information of the first use of the disposable part stored in the non-volatile memory of the disposable part in order to determine the time elapsed since the disposable part was first used.

13. An imaging system according to claim 11 or 12, characterized in that said timing device comprises a timer which continuously updates the time of use data stored in the non-volatile memory component of the disposable part (1) as long as the disposable part is in use.

14. An imagining system according to any one of claims 1-13, characterized in that said non-volatile memory component is a part of the camera electronics in the disposable part (1).

15. An imaging system according to any one of claims 1-14, characterized in that said disposable part (1) has an on/off switch (10).
