Monitoring System

Abstract

The invention relates to a monitoring system for endoscopic treatments, in particular for endourological interventions, comprising an evaluation unit (10) and a guide wire (20) which has at least one measurement device (40). According to the invention, the evaluation unit (10) can receive data of the at least one measurement device (40), and the evaluation unit (10) comprises a comparator that compares the data with a comparison value.

Claims

1. Monitoring system for endoscopic treatments, in particular for use in endourological interventions, comprising an evaluation unit and a guidewire, which comprises at least one measuring device, wherein the evaluation unit can receive data of the at least one measuring device, so as to monitor the ambient conditions in a treatment zone, and wherein the evaluation unit comprises a comparator, which compares the data with a comparison value to determine whether the ambient conditions lie within an unfavorable range.

2. Monitoring system according to claim 1, wherein the at least one measuring device acquires a pressure or pressure change and/or a temperature or temperature change.

3. Monitoring system according to claim 1, wherein the evaluation unit comprises an input unit, which can be used to adjust the comparison value.

4. Monitoring system according to claim 1, wherein the evaluation unit comprises an output unit, which generates an output signal that indicates when the comparison value has been exceeded.

5. Monitoring system according to claim 4, wherein the output device generates various output signals, depending on what comparison value is exceeded.

6. Monitoring system according to claim 1, wherein the evaluation unit determines how often and/or how long and/or by how much the comparison value is exceeded.

7. Monitoring system according to claim 1, wherein the evaluation unit generates a control signal for another device when the comparison value is exceeded.

8. Monitoring system according to claim 1, wherein the at least one measuring device can be calibrated by the evaluation unit.

9. Monitoring system according to claim 1, wherein the at least one measuring device is arranged at a distal end of the guidewire.

10. Monitoring system according to claim 1, wherein at least one measuring device is a relative pressure sensor, and at least one additional measuring device is an absolute pressure sensor, and wherein the relative pressure sensor is arranged at a distal end of the guidewire, while the absolute pressure sensor is preferably arranged at the proximal end of the guidewire.

11. Monitoring system according to claim 1, wherein at least one measuring device is a pressure sensor, and at least one additional measuring device is a temperature sensor.

12. Method for monitoring ambient conditions during endoscopic treatments, in particular for acquiring pressures in endourological interventions, with a monitoring system, which exhibits an evaluation unit and a guidewire with at least one measuring device, the method comprising the following steps: Receiving data of the at least one measuring device via the evaluation unit; Comparing the data with a comparison value and/or a correction value.

13. Method for analyzing ambient conditions according to claim 12, additionally comprising the following steps: Zeroing out a pressure level acquired by the at least one measuring device; Starting a treatment, in particular an endoscopic treatment or an endourological intervention.

14. Guidewire with at least one measuring device according to claim 1.

15. Monitoring system according to claim 3, wherein the evaluation unit comprises a plurality of comparison values.

16. Monitoring system according to claim 7, wherein said another device comprises a suction rinsing system.

17. Monitoring system according to claim 8, wherein the calibration of the at least one measuring device comprising setting a pressure and/or temperature level to zero.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0032] Additional advantages and features arise from the following description of a preferred embodiment of the monitoring system according to the invention, the method according to the invention, as well as the guidewire according to the invention, drawing reference to the attached FIGURE.

[0033] Shown on:

[0034] FIG. 1: is a schematic view of a preferred embodiment of the monitoring system.

DETAILED DESCRIPTION

[0035] FIG. 1 presents a schematic view of a guidewire 20, which exhibits a measuring device 40 at a distal end 21. A measuring device 40 is also provided at a proximal end 22 of the guidewire 20. The guidewire 20 is electrically connected with an evaluation unit 10 by a cable 12. As an alternative, the connection can preferably also be wireless. The evaluation unit 10 basically must not also be arranged separately from the guidewire 20, but can rather comprise part of the latter. Advantageously one end of the guidewire 20 is also provided with a control panel/handset, which comprise the evaluation unit 10. An input unit and output unit can also be provided in the control panel/handset, so as to both enable user inputs and relay output signals. Not shown is a current or voltage supply, which might also have to be provided for the measuring devices 40. A diameter d of the guidewire ranges from 0.15 mm to 3 mm, favorably in a range of 0.4 to 2 mm, and very especially preferably ranges from about 0.8 to 1.2 mm. The diameter d can vary over the length of the guidewire, but rather tends to be constant in preferred embodiments. Reference sign S schematically denotes that control signals are here output proceeding from the evaluation unit 10, so as to regulate or control another device, for example a suction-rinsing system.
