专利说明:

The invention relates to a testing device for checking at least one medical electrode, having the features of the preamble of claim 1.
To be checked electrodes go z. Example from US 2015/0045869 A1. There, two jointly prepared medical electrodes in the form of defibrillation electrodes are shown.
Previous test devices functioned on a purely manual basis by visually inspecting by an operator the presence of contact between terminals of the electrode and the actual electrode surface (baffle), and determining the electrical connection by means of a multimeter. The test step was to be provided separately from the value-adding processes. Such a procedure is error-prone and time-consuming.
The object of the invention is to provide a testing device which permits at least partially automated testing, which can take place during a value-adding process.
This object is achieved by a test device having the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.
The test device according to the invention operates without the production of a mechanical electrical contact between the medical electrode (s) to be tested and the measuring electrode (s). The testing itself can be done fully automatically, the assembly of the tester can be done at least partially automatically.
In itself, a single (first) measuring electrode is sufficient to carry out the test procedure. To increase safety (in particular safety against incorrect operation and manipulation safety and measurement stability of the test), the arrangement of at least one second measuring electrode can be provided. Only if the
The evaluation unit determines with respect to the signals of both resulting capacities that the medical electrode has passed the test, this is released. In such an embodiment, it is provided that the test device further comprises at least one second measuring electrode, which can be arranged relative to the first medical electrode to be examined such that the at least one second measuring electrode and the first medical electrode to be checked form a second capacitance, the evaluation device, is configured to determine at least a second test result with respect to the second capacitance from a measured impedance curve of an impedance generated in response to an AC voltage generated by the signal generating device due to the second capacitance.
In this case, it can preferably be provided that the areas of the at least one first and the at least one second measuring electrode are of different sizes. This allows the use of two different release windows with respect to the one medical electrode to be tested, even when using only one AC voltage with one frequency.
As such, the first and second measuring electrodes may be arranged arbitrarily with respect to the medical electrode to be tested (for example, side by side).
However, in order to achieve a compact arrangement, it is preferably provided that the at least one first measuring electrode is designed as a circular ring and the at least one second measuring electrode is arranged inside the circular ring and is electrically separated from the circular ring by an insulator.
It is preferably provided that the test device is designed for the common or simultaneous checking of at least one first medical electrode and one second medical electrode. For example, defibrillation electrodes have a pair of electrodes, and other medical electrodes may be functional in smaller (i.e., in isolation) or greater numbers
In this embodiment, the test apparatus further comprises: at least one third measuring electrode, which can be arranged relative to the second medical electrode to be examined so that the at least one third measuring electrode and the second medical electrode to be examined form a third capacitance, wherein "the signal generating device is adapted to generate via an AC voltage, by means of which the third capacitance can be acted upon" the evaluation device is adapted to a measured
Impedance characteristic of an AC voltage generated in response to the generated by the signal generating device due to the third capacitance caused impedance to determine at least a first test result with respect to the third capacitance
Of course, the common or simultaneous verification can be performed such that the signal generating device sequentially applies the AC voltage to the individual capacitors and / or that the evaluation device successively measures the impedance characteristics with respect to the individual capacitors. However, in the case of a joint or simultaneous check, no mechanical manipulation of the medical electrodes to be checked is required.
An embodiment of the invention will be discussed with reference to the figures. Show it:

In the following, reference numerals Cu, C- | 2, C21, C22 are used for the first to fourth capacitances which may exist between different medical electrodes to be inspected and different measuring electrodes. Of course, the use of different short names does not exclude that the numerical values of the different capacities may be the same.
The first exemplary embodiment of a testing device according to the invention shown in FIGS. 1 and 2 is suitable for the joint testing of two medical electrodes (a first and a second medical electrode 1, 1 '), in each case with two measuring electrodes (with respect to the first medical examination to be tested Electrode 1 are the first and second measuring electrodes 2, 5, and in relation to the second medical electrode 1 'to be tested, these are the third and fourth measuring electrodes 7, 8). During the test, the four capacitors Cu, Ci2, C2i, C22 are present.
The test device has a receiving region 16, which is designed here for the simultaneous recording of two medical electrodes 1, 1 'to be tested. The medical electrodes 1, 1 'to be tested are to be arranged in the receiving region 16 such that their actual electrode surfaces (guide surfaces) point away from the receiving region 16. The back sides of the medical electrodes 1, 1 'to be tested are fixed for testing by means of a vacuum (the openings 12 are used for this purpose). Thus, there is no direct electrical contact between the guide surfaces of the medical electrodes 1, 1 'to be tested and the measuring electrodes 2, 5, 7, 8. If the medical electrodes 1, 1' to be tested are to be arranged with their front sides in the receiving region 16, Separate insulators would have to be arranged between the fins and the measuring electrodes.
The second exemplary embodiment of a test device according to the invention shown in FIGS. 4 and 5 is suitable for testing a medical electrode 1 and has two measuring electrodes 2, 5. These are arranged side by side, but could also be designed as in the exemplary embodiment of FIGS. 1 and 2. During the test, the two capacitors Cu, C12 are present. The carrier 9 may be formed as in the embodiment of FIGS. 1 and 2.
Fig. 3 shows very schematically the structure of a test device according to the invention according to the first embodiment with: - a first and a second measuring electrode 2, 5, which are so relative to the first to be examined medical electrode 1 can be arranged that the first measuring electrode 2 and the first medical electrode 1 to be checked form a first capacitance Cu and the second measuring electrode 5 and the first medical electrode 1 to be examined form a second capacitance C12 - a third and a fourth measuring electrode 7, 8, which are relative to the second medical electrode T to be checked can be arranged, that the third measuring electrode 7 and the second medical electrode to be examined 1 'form a third capacitor C21 and the fourth measuring electrode 8 and the second medical electrode to be tested T form a fourth capacitance C22 - a signal generating device 3, via which an AC voltage can be generated is, mitt which is the first to fourth capacitance Cu, C12, C21, C22 can be acted upon "an evaluation device 4, which is adapted to a measured impedance curve I of one in response to the first to fourth capacitance Cu, C12, C21, C22 evoked impedance determine first to fourth test results Pu, P12, P21, P22 with respect to the first to fourth capacitances Cu, C12, C21, C22, and an overall test result P with respect to the first to fourth capacitances Cu, Ci2, C21, C22 to determine
A detailed illustration of FIG. 3 is shown in FIG. 6. It can be seen that the signal generating device 3 comprises a frequency generator 17 and a clock generator 18. The frequency generator 17 supplies the two medical electrodes 1, 1 'to be tested with an alternating voltage. The clock generator 18 has an output A and an output B. The output A is assigned to the first medical electrode 1 to be tested and is linked via an AND gate 14 to one of the outputs of the frequency generator 17 assigned to the first medical electrode 1 to be tested. The output B is assigned to the second medical electrode 1 'to be tested and is linked via an AND gate 14 to an output of the frequency generator 17 assigned to the second medical electrode 1' to be tested. This ensures that the two medical electrodes 1, 1 'to be tested are not simultaneously exposed to alternating voltage.
The outputs A, B of the clock generator 18 are each further associated with a flip-flop 20 of the evaluation device 4. It is thus possible to allocate which of the two medical electrodes 1, 1 'to be tested are currently receiving test signals.
Each of the four capacitances Cu, Ci2, C2i, C22 is part of a resonant circuit 19 with an inductance and an electrical resistance (only one of the resonant circuits is provided with the reference numeral 19 for the sake of clarity).
The impedance profile I resulting from the applied alternating voltage in each resonant circuit 19 is fed to an analysis device 13 of the evaluation device 4, which checks whether the impedance profile I is in a predetermined window. If this is the case, the respective analysis device 13 outputs a positive test result Pu, P12, P21, P22. Via an AND gate 14, a test result is formed for each of the medical electrodes 1, T to be tested. Via a further AND gate 14, an entire test result P is formed for both medical electrodes 1, 1 'to be tested and output via the output 15.
