(effect of B. path interruptions switch 52)
Next, 52 effect is switched to the path interruption of present embodiment, while being carried out with comparative example (comparative example 1,2)
Compare, while being described in detail.
(comparative example 1)
Fig. 5 is the square frame being monolithically fabricated for schematically showing the conduit system (conduit system 106) involved by comparative example 1
Figure.The conduit system 106 of the comparative example 1 replaces repeater with setting repeater 105 in the conduit system 6 of present embodiment
5 system is corresponding.
It is different from repeater 5 in the repeater 105, it is not provided with road on temperature measurement signal St outgoing route
Footpath blocking switch 52.Therefore, in the comparative example 1, in repeater 105, the noise letter that circuit (amplifier 51 etc.) occurs
Number Sn (electromagnetic wave etc.) has the risk for being overlapped in test waveform signal Sw.Specifically, firstly, because temperature measurement signal St
Distribution (such as foregoing thermocouple 113) is connected to the circuit in repeater 105, then the noise signal Sn from this circuit must
So it is overlapped in temperature measurement signal St.In addition, the vicinity of the distribution in temperature measurement signal St, is configured with test waveform signal
Sw distribution.That is, in example distribution 60b as the aforementioned, these temperature measurement signals St and test waveform signal Sw's is each
Bar distribution parallel deployment.Therefore, in repeater 105, for test waveform signal Sw, will also have by temperature measurement signal
Risk (dotted arrow in reference picture 5) overlapping with noise signal Sn St.
Specifically, as the test waveform signal Sw101 shown in such as Fig. 6, in this comparative example 1, this is caused
The test waveform (electrocardiographic wave) come is overlapping with the noise signal Sn of high frequency.If noise signal Sn is overlapped in by this way
Test waveform, then just having causes to be difficult to obtain (display) good test waveform, measuring accuracy in electrocardio map display device 2
The risk of reduction.
Further, because it is for example following the reasons why, it has in the neighbouring configuration testing ripple of temperature measurement signal St distribution
Shape signal Sw distribution.That is, because the axle 11 of ablation catheter 1 it is a diameter of as small as possible, be difficult to survey temperature
Physically and (implementation is electrically isolated between amount signal St distribution (thermocouple 113 etc.) and test waveform signal Sw distribution
Noise countermeasure).
(comparative example 2)
Herein, in order to remove overlapping noise signal Sn like this, for example, it may be considered that test waveform signal Sw's
The method (being used as comparative example 2) of wave filter (for example, LPF (Low Pass Filter)) is set on path.
However, as the test waveform signal Sw102 shown in such as Fig. 7, the test waveform after by wave filter
In, the inclination of the raising and lowering of waveform slows down (dotted arrow in reference picture 7, peak value is reduced and waveform is gentle), causes not
Easily observe test waveform.Therefore, doctor cannot be met to want to observe the original test waveform (test waves of loyalty reflection script
Shape) requirement.Add, as shown in the symbol P102 in Fig. 7, by filter process, also having causes the survey for being present in script
Try the risk that the small-signal in waveform disappears.For all these reasons, even if being applicable the method for the comparative example 2, as a result also lead
The risk for causing measuring accuracy to decline.
(present embodiment)
In this regard, in the conduit system 6 of present embodiment, as shown in Fig. 1, Fig. 3, Fig. 4, in the temperature from ablation catheter 1
On the temperature measurement signal St of sensor (thermocouple 113 etc.) output outgoing route, the outgoing route can be interdicted by being provided with
St path interruption switch 52.
Specifically, as shown in Figure 8 A, when path interruption switch 52 is set to on-state, temperature measurement signal
St outgoing route turns into conducting state, and temperature measurement signal St is provided to amplifier 51.That is, warm as carrying out
The state of measurement is spent, the temperature measurement signal St ' after signal amplification is provided to the control unit 35 in supply unit 3.
On the other hand, as shown in Figure 8 B, when path interruption switch 52 is set off state, temperature measurement signal St
Outgoing route turn into blocking state, temperature measurement signal St can not be supplied to amplifier 51.That is, as stopping temperature
The state of measurement, the temperature measurement signal St ' after signal amplification can not be supplied to the control unit 35 in supply unit 3.
By setting this path interruption switch 52, the circuit from the outgoing route for being connected to temperature measurement signal St
The noise signal Sn of (amplifier 51 etc.), can be interrupted on this temperature measurement signal St outgoing route.That is,
Noise signal Sn occurring source (foregoing circuit) can be separated from temperature measurement signal St outgoing route.
The result is that：As the test waveform signal Sw shown in such as Fig. 9, in the present embodiment with above-mentioned comparative example
1 is different, in repeater 5, noise signal Sn can be reduced or avoided and is overlapped in by temperature measurement signal St outgoing route
Test waveform signal Sw risk.In addition, it is different from above-mentioned comparative example 2, also become gentle without easily sight without result in test waveform
Examine, small-signal disappear risk.
As described above in the present embodiment, because in the temperature survey letter of the temperature sensor output from ablation catheter 1
On number St outgoing route, there is provided the path interruption switch 52 of the outgoing route can be interdicted, so can be reduced or avoided
Noise signal Sn is overlapped in test waveform signal Sw risk.Therefore, it is possible to obtain good test waveform, test can be improved
Precision.
In addition, because being provided with path interruption switch 52 in repeater 5, temperature can be interdicted in repeater 5
Spend measurement signal St outgoing route.Thus, noise signal Sn occurring source is defined to from ablation catheter 1 to repeater 5
On path.It is overlapping to test waveform signal Sw therefore, it is possible to make noise signal Sn more be not easy.
Furtherly, because being provided with amplification temperature measurement signal St amplifier 51 in repeater 5, and than this
Amplifier 51 is closer to being configured with path interruption switch 52 on the outgoing route of the side of ablation catheter 1, so in repeater 5, just
Can relatively on hand side blocking outgoing route.Therefore, the antenna effect of temperature measurement signal St outgoing route diminishes,
Also the generation of noise signal can be suppressed.
Add, can connecing according to the operating and setting path interruption of the operator of repeater 5 switch 52 because employing
The construction of logical state or off-state, thus such as can according to checking, the situation for the treatment of, on opportunity desired by operator,
Carry out the blocking of temperature measurement signal St outgoing route.Therefore, convenience when such inspection, treatment can be carried
It is high.
Hereinafter, the other embodiment (the 2nd~the 4th embodiment) to the present invention is illustrated.Further, pair with it is the 1st real
