The top ends of the 3rd insulating properties pipe 28 (apart from about the 10mm of top) is inserted into the 3rd lumen 13 of multi-lumen tube 10, and thus, the 3rd lumen 13 that the 3rd insulating properties pipe 28 and the 3rd wire group 43G extend links.
The 3rd insulating properties pipe 28 that links with the 3rd lumen 13 extends to the top end face 50A that adapter 50(pin terminal is configured by the endoporus of the 2nd protecting tube 62 that extends in the inside of handle 20) near, form base end part with the 3rd wire group 43G and guide near the adapter 50 slotting path.Thus, from multi-lumen tube 10(the 3rd lumen 13) extended the 3rd wire group 43G can not twine, can extend in the inside of handle 20 (endoporus of the 3rd insulating properties pipe 28).
Be dispersed into 4 wires 43 that consist of it from extended the 3rd wire group 43G of the cardinal extremity opening of the 3rd insulating properties pipe 28, these wires 43 utilize respectively welding and the pin terminal that is disposed at the top end face 50A of adapter 50 to be connected and fixed respectively.Here, the wire 43 that consists of the 3rd wire group 43G is connected zone that fixing pin terminal (pin terminal 53) is configured as " the 3rd terminal group is regional ".
Here, the constituent material as insulating properties pipe (the 1st insulating properties pipe 26, the 2 insulating properties pipes 27 and the 3rd insulating properties pipe 28) can example illustrate polyimide resin, polyamide, polyamide-imide resin etc.Wherein, particularly preferably hardness is higher, inserts easily admittance line group, the polyimide resin that shaping can be thinner.
As the wall thickness of insulating properties pipe, be preferably 20~40 μ m, a preferred example that illustrates is 30 μ m.
In addition, the constituent material of the protecting tube (the 1st protecting tube 61 and the 2nd protecting tube 62) that is interpolated as the insulating properties pipe, can illustration " Pebax " (registered trade mark of ARKEMA company) etc. the nylon based elastomers.
According to the defibrillation probe 100 with above-mentioned such present embodiment that consists of, the 1st wire group 41G is in the 26 interior extensions of the 1st insulating properties pipe, the 2nd wire group 42G is in the 27 interior extensions of the 2nd insulating properties pipe, the 3rd wire group 43G is in the 28 interior extensions of the 3rd insulating properties pipe, thus in the inside of handle 20, the isolation of also the 1st wire group 41G, the 2nd wire group 42G and the 3rd wire 43G can being insulated fully.Its result when having applied the required voltage of defibrillation, can prevent the 1st wire group 41G, the 2nd wire group 42G and the short circuit between the 3rd wire 43G (especially near the short circuit between the extended wire group opening of lumen) of the inside of handle 20 reliably.
And; inside at handle 20; the 1st insulating properties pipe 26 is by 61 protections of the 1st protecting tube; the 2nd insulating properties pipe 27 and the 3rd insulating properties pipe 28 are by 52 protections of the 2nd protecting tube; thus, for example can prevent the situation that when the deflection operation of the top ends of multi-lumen tube 10, contacts, nuzzle up and cause the insulating properties pipe to damage because of the component parts (movable member) of carrying button 22.
The top end face 50A that defibrillation probe 100 in the present embodiment possesses the adapter 50 that a plurality of pin terminals are configured is divided into the 1st terminal group zone, the 2nd terminal group zone and the 3rd terminal group zone, and with wire 41, wire 42 and wire 43 mutual partition walls 55 of isolating.
Divide the partition wall 55 in the 1st terminal group zone, the 2nd terminal group zone and the 3rd terminal group zone by insulative resin machine-shaping is formed for the catheter-like that has tabular surface in both sides.Insulative resin as consisting of partition wall 55 is not particularly limited, and can use the common resins such as polyethylene.
The thickness of partition wall 55 is 0.1~0.5mm for example, a preferred example is shown is 0.2mm.
The height of partition wall 55 (distance from the cardinal extremity edge to top edge) need to be higher than the top end face 50A of adapter 50 and the standoff distance of insulating properties pipe (the 1st insulating properties pipe 26 and the 2nd insulating properties pipe 27), when this standoff distance was 7mm, the height of partition wall 55 for example was 8mm.On the partition wall of height less than 7mm, the cardinal extremity that its top edge is positioned at than insulating properties pipe leans on tip side.
According to such formation, can be reliably and fitly isolation consist of the wire 41(of the 1st wire group 41G from the cardinal extremity part of the extended wire 41 of cardinal extremity opening of the 1st insulating properties pipe 26) and the wire 42(of formation the 2nd wire group 42G from the cardinal extremity part of the extended wire 42 of cardinal extremity opening of the 2nd insulating properties pipe 27).
In the situation that does not possess partition wall 55, wire 41 and wire 42 fitly can't be isolated (division), might cause their swinging cross.
And, thereby the wire 41 of formation the 1st wire group 41G of different voltage and the wire 42 that consists of the 2nd wire group 42G are mutually isolated by partition wall 55 and can not contacted mutually to be applied in polarity, therefore when using defibrillation probe 100, even apply the required voltage of intracardiac defibrillation, in the cardinal extremity part of the wire 41(that consists of the 1st wire group 41G from the extended wire 41 of cardinal extremity opening of the 1st insulating properties pipe 26) and the wire 42(of formation the 2nd wire group 42G from the cardinal extremity part of the extended wire 42 of cardinal extremity opening of the 2nd insulating properties pipe 27) between can not be short-circuited yet.
In addition, when making the defibrillation probe, in the situation about when wire and pin terminal are connected and fixed, making a mistake, for example in the situation that the wire 41 that will consist of the 1st wire group 41G has been connected with pin terminal in the 2nd terminal group zone, this wire 41 can be found the mistake that connects thus easily across next door 55.
In addition, consist of the wire 43(pin terminal 53 of the 3rd wire group 43G) with wire 42(pin terminal 52) in the lump by partition wall 55 from wire 41(pin terminal 51) isolation, but be not limited to this, also can with wire 41(pin terminal 51) in the lump by partition wall 55 from wire 42(pin terminal 52) isolation.
In defibrillation probe 100, the cardinal extremity that the top edge of partition wall 55 is positioned at than the cardinal extremity of the 1st insulating properties pipe 26 and the 2nd insulating properties pipe 27 all leans on tip side.
Thus, from the extended wire of cardinal extremity opening (consisting of the wire 41 of the 1st wire group 41G) of the 1st insulating properties pipe 26 with between the extended wire of cardinal extremity opening (consisting of the wire 42 of the 2nd wire group 42G) of the 2nd insulating properties pipe 27, partition wall 55 always exists, and can prevent reliably that wire 41 from contacting the short circuit that causes with wire 42.
As shown in Figure 8, from the cardinal extremity opening of the 1st insulating properties pipe 26 extend and 8 wires 41 being connected and fixed with the pin terminal 51 of adapter 50, from the cardinal extremity opening of the 2nd insulating properties pipe 27 extend and 8 wires 42 being connected and fixed with the pin terminal 52 of adapter 50, from the cardinal extremity opening of the 3rd insulating properties pipe 28 extend and 4 wires 43 being connected and fixed with the pin terminal 53 of adapter 50 around fixed by resin 58, separately shape keeps fixing thus.
Keep the resin 58 of the shape of wire to form and cylindric with the footpath of adapter 50, in the inside of this resin molded body, be in the base end part of pin terminal, wire, insulating properties pipe and the state that partition wall 55 is embedded into.
And, be embedded into the formation of the inside of resin molded body according to the base end part of insulating properties pipe, extend out to be connected with the pin terminal from the cardinal extremity opening of insulating properties pipe and be fixed as wire (cardinal extremity part) integral body of ending and covered fully by resin 58, the shape of wire (cardinal extremity part) fully can be kept fixing.
In addition, the height of resin molded body (distance from the cardinal extremity face to top end face) preferably is higher than the height of partition wall 55, and the height of next door plate 55 is the situation of 8mm, for example is made as 9mm.
Here, be not particularly limited as the resin 58 that consists of resin molded body, but preferred thermosetting resin or the ray hardening resin of using.Particularly, can illustration ammonia ester the hardening resin of system, epoxy system, ammonia ester-epoxy system.
According to formation as described above, because the shape of wire is kept fixing by resin 58, so when making defibrillation probe 100 (at the inside of handle 20 mounted connector 50 time), can prevent the situation (for example, the coated with resin fracture of wire) of twining or causing with the EDGE CONTACT of pin terminal damaging from the extended wire of the cardinal extremity opening of insulating properties pipe.
As shown in Figure 1, the defibrillation probe 100 that consists of the probe system of present embodiment possesses and has probe sequence storage part 111, the memorizer 110 of first link information storage part 112 and event information storage part 113.
The memorizer 110 that defibrillation probe 100 possesses for example is made of the memory chip of the inside that is contained in handle 20.

(2) measurement of the 1DC electrode group 31G of defibrillation probe 100 and the resistance value between the 2DC electrode group 32G,
(3) after the employed supply unit of event that defibrillation probe 100 carries out is removed, this defibrillation probe 100 is connected again the operation of identical or different supply units.
When having carried out defibrillation by defibrillation probe 100, the information of setting value, the actual output voltage that applies and the output time of the electric energy that will apply between the resistance value (intracardiac resistance value) between 1DC electrode group 31G and the 2DC electrode group 32G, the above-mentioned electrode group is written into event information storage part 113 in the lump with the sequence information of the supply unit that the moment of carrying out this defibrillation and this moment are connected.
For example, in the structure of the memorizer 110 shown in the above-mentioned table 1, in the event 2 of event information storage part 113, as event, the serial number (10011) of the supply unit that the moment (December was 10: 06: 12 on the 5th in 2009) that the resistance value between the electrode group (75 Ω), energy settings value (15J), output voltage (300V) and output time (13.5msec) and defibrillation are carried out and this moment are connected is writing events information storage part 113 in the lump with defibrillation.In addition, for event 3,4 and 7 too.
For the measurement of the resistance value between 1DC electrode group 31G and the 2DC electrode group 32G, usually owing to before defibrillation, carry out, although so can be included in the event of defibrillation, but in the situation that defibrillation does not carry out afterwards, the measurement of resistance value is identified as independent event, and the sequence information of measured resistance value and the moment of measurement and the supply unit that is connected is written into event information storage part 113 in the lump.
For example, in the structure of the memorizer 110 shown in the above-mentioned table 1, in the event 1 of event information storage part 113, the resistance value between the electrode group (75 Ω) is written into event information storage part 113 in the lump with the serial number (10011) of measuring the supply unit that is connected the moment (December was 10: 05: 00 on the 5th in 2009) and this moment.
In addition, in event 6, the resistance value between the electrode group (79 Ω) is written into event information storage part 113 in the lump with the serial number (10032) of measuring the supply unit that is connected the moment (December was 10: 53: 22 on the 5th in 2009) and this moment.
In the probe system of present embodiment, when having connected supply unit to defibrillation probe 100, in the situation of initial connection in this connection, the sequence information of this moment and this supply unit is written into first link information storage part 112, and when again connecting identical or different supply units, these information are written into event information storage part 113.
For example, in the structure of the memorizer 110 shown in the above-mentioned table 1, in the event 5 of event information storage part 113, the serial number (10032) of the moment (December was 10: 40: 08 on the 5th in 2009) that again connects and the supply unit that again connects is written into event information storage part 113.
In addition, in event 8, the serial number (10055) of the moment (December was 11: 30: 00 on the 6th in 2009) that again connects and the supply unit that again connects is written into event information storage part 113.

Here, having connected the method that the situation of supply unit 700 detects as subtend defibrillation probe 100 is not particularly limited, for example can enumerate to be arranged on when connecting and flow through the such circuit of weak current, perhaps the probe adapter 72 of supply unit 700 be arranged the method for physical switch and so on.
In addition, for " initial " connects or again connect for being connected in this defibrillation probe 100 of supply unit 700, arithmetic processing section 75 is with reference to the first link information storage part 112 in the memorizer 110 of this defibrillation probe 100, being judged as when not storing information in the first link information storage part 112 is that " initial " connects, and being judged as when storing information in the first link information storage part 112 is again to connect.
Arithmetic processing section 75 is when utilizing defibrillation probe 100 to carry out defibrillation, obtain the resistance value (the intracardiac resistance value that measures first when carrying out defibrillation) between 1DC electrode group 31G and the 2DC electrode group 32G, the setting value (input value of energy settings switch 742) of the electric energy that will apply between 1DC electrode group 31G and the 2DC electrode group 32G, the information of output voltage and output time (the actual voltage that applies and time) writes the sequence information (sequence information that memorizer 752 is stored) of these information and the moment of carrying out this defibrillation (moment of internal clocking 753) and the supply unit 700 that is connected event information storage part 113(in the memorizer 110 of defibrillation probe 100 in the lump with reference to the event 2 of above-mentioned table 1,3,4,7).
In addition, when after the 1DC electrode group 31G of defibrillation probe 100 and the resistance value between the 2DC electrode group 32G are measured, not carrying out defibrillation, arithmetic processing section 75 is identified as event with the measurement of resistance value, the sequence information of moment of the resistance value of measuring and the measurement of having carried out resistance value and the supply unit 700 that is connected is write in the lump the event 1,6 of the above-mentioned table 1 of event information storage part 113(reference in the memorizer 110 of defibrillation probe 100).
Thus, also can record the data of the intracardiac resistance value when not carrying out defibrillation.
And, arithmetic processing section 75 is after the supply unit of the event of carrying out for defibrillation probe 100 is removed, when again connecting identical or different supply units 700 to this defibrillation probe 100 (with storing defibrillation probe 100 constantly in the first link information storage part 112 at memorizer 110 and being connected), this is identified as event, the sequence information of moment of again connecting and supply unit 700 is write event information storage part 113(in the memorizer 110 of defibrillation probe 100 with reference to the event 5,8 of above-mentioned table 1).
Thus, can record the resume of (exchange) that again connect supply unit.
According to the probe system of present embodiment, can record the resume of the event (measurement of the resistance value between defibrillation, electrode group, the again connection of supply unit) that defibrillation probe 100 carries out.And, the information that these events relate to is not to be stored in the supply unit side, but be stored in event information storage part 113 in the memorizer 110 of defibrillation probe 100, even therefore carry out the event of 1 defibrillation probe 100 with a plurality of supply units, the information that these events relate to can not be distributed to a plurality of supply units yet.

Below describe according to a flow chart shown in Figure 11 example to the defibrillation therapy of the intracardiac defibrillation probe system of present embodiment.
(1) at first, connect supply unit 700 to defibrillation probe 100.Particularly, utilize connector-cable C1 with probe adapter 72 bindings (with reference to Step1, Fig. 9 of Figure 11 A) of adapter 50 with the supply unit 700 of defibrillation probe 100.
(2) detect the probe sequence storage part 111 of arithmetic processing section 75 from the memorizer of defibrillation probe 100 of this supply unit 700 that has connected the situation of supply unit 700 to defibrillation probe 100 and read sequence information, and it is initial the connection or the again connection of identical or different supply units in order to judge that this is connected in this defibrillation probe 100, with reference to the first link information storage part 112 in the memorizer 110, judge the information that wherein whether has been written into, do not enter Step3 when in first link information storage part 112, having writing information, when having write information, enter Step4(with reference to Step2, Figure 12).
When (3) in first link information storage part 112, not having writing information, the arithmetic processing section 75 of supply unit 700 will connect moment (moment of internal clocking 753) of supply unit 700 and supply unit 700 in Step1 sequence information (sequence information that memorizer 752 is stored) writes the first link information storage part 112 in the memorizer 110 of defibrillation probe 100, and enters Step5(with reference to Step3, Figure 12).
When (4) in first link information storage part 112, having write information, the arithmetic processing section 75 of supply unit 700 will connect moment of supply unit 700 and supply unit 700 in Step1 sequence information writes the event information storage part 113 in the memorizer 110 of defibrillation probe 100, and enters Step5(with reference to Step4, Figure 12).
(5) in radioscopic image, confirm the position of the electrode (the formation electrode of 1DC electrode group 31G, 2DC electrode group 32G and base end side potential-measuring electrode group 33G) of defibrillation probe 100, and select to invest from heart potential measuring unit 900(note the electronic pads of surface) input to the part of the heart potential information (12 lead electrocardiogram) of ecg scanning instrument 800, and from the arithmetic processing section 75(Step5 of electrocardiogram input connector 77 input power devices 700).At this moment, the part of the heart potential information of input arithmetic processing section 75 is shown in heart potential information display section 78(with reference to Figure 13).
In addition, from the formation electrode of the 1DC electrode group 31G of defibrillation probe 100 and/or 2DC electrode group 32G via probe adapter 72, switching part 76, ecg scanning instrument adapter 73 input to the heart potential information of ecg scanning instrument 800, the heart potential information that inputs to ecg scanning instrument 800 via probe adapter 72, ecg scanning instrument adapter 73 from the formation electrode of the base end side potential-measuring electrode group 33G of defibrillation probe 100 is shown in ecg scanning instrument 800 monitor (omitting diagram omits).
(6) then, input is as the mode selector switch 741(Step6 of external switch 74).Supply unit 700 in the present embodiment is " heart potential measurement pattern " in original state, and switching part 76 is selected the 1st contact, thus the path of guaranteeing to arrive via switching part 76 from probe adapter 72 ecg scanning instrument adapter 73.
(7) when mode selector switch 741 is transfused to, the arithmetic processing section 75 of supply unit 700 judges that the moment of the first link information storage part 112 from the memorizer 110 that writes defibrillation probe 100 begins elapsed time till the moment of last writing events information storage part 113 and whether surpassed the use binding hours of the probe that the memorizer 752 of arithmetic processing section 75 stores, enter Step8 when surpassing being judged as not, be judged as above the time, can't carry out later action and become " end " (Step7).
Here, being connected in this defibrillation probe 100 when being initial connection of the supply unit 700 in Step1 (via Step2,3,5,6 situation) owing to do not have writing information in event information storage part 113, therefore can enter Step8.On the other hand, being connected in this defibrillation probe 100 of supply unit 700 in Step1 is (via Step2,4,5,6 situation) when again connecting, and the moment of last writing events information storage part 113 becomes the moment that again connects supply unit 700 that writes in Step4.
In addition, when turning back to Step6 from Step22 described later (via Step22,6 situation), the moment of last writing events information storage part 113 becomes the moment that applies (defibrillation) of having carried out electric energy in Step17 described later.
(8) when being judged as the elapsed time that begins from the moment that writes first link information storage part 112 till the moment of last writing events information storage part 113 when surpassing the use binding hours of probe, arithmetic processing section 75 switches to " defibrillation mode " (Step8 of Figure 11 B) with the pattern of supply unit 700 from " heart potential measurement pattern ".
(9) as shown in figure 14, when thereby mode selector switch 741 is transfused to when switching to defibrillation mode, control signal according to arithmetic processing section 75, the contact of switching part 76 is switched to the 2nd contact, guaranteed to be cut off (Step9) from probe adapter 72 via the path that switching part 76 arrives ecg scanning instrument adapters 73 from the path of probe adapter 72 via switching part 76 arrival arithmetic processing section 75.When switching part 76 has been selected the 2nd contact, therefore heart potential information from the formation electrode of the 1DC electrode group 31G of defibrillation probe 100 and 2DC electrode group 32G can't input to ecg scanning instrument 800(, also this heart potential information can't be sent to arithmetic processing section 75.)。But the heart potential information from the formation electrode of base end side potential-measuring electrode group 33G via switching part 76 is not input to ecg scanning instrument 800.
(10) when the contact of switching part 76 is switched to the 2nd contact, measure the 1DC electrode group (31G) of defibrillation probe 100 and the resistance value (Step10) between the 2DC electrode group (32G).Can be shown in the lump heart potential information display section 78(with reference to Figure 14 from probe adapter 72 with the part from the heart potential information of heart potential measuring unit 900 of input arithmetic processing section 75 via the resistance value that switching part 76 is input to arithmetic processing section 75).
(11) contact of switching part 76 is switched to the 1st contact, recovers (Step11) from probe adapter 72 via the path that switching part 76 arrives ecg scanning instrument adapter 73.
In addition, (above-mentioned Step9~Step10) for example is between 1 second the contact of switching part 76 time of being selected to the 2nd contact.
(12) arithmetic processing section 75 judges whether the resistance value of measuring surpasses certain value in Step10, when not surpassing, enter next Step13(for the preparation that applies DC voltage), when surpassing, return the location confirmation of the electrode of Step5(defibrillation probe 100) (Step12).
Here, when resistance value has surpassed certain value, mean that 1DC electrode group and/or 2DC electrode group do not have fully and regulation position (for example the tube wall of Coronary vein, the inwall of right ventricle) butt, therefore need to return the position that Step5 adjusts electrode again.
Like this, can be only just apply voltage during butt fully at the 1DC electrode group of defibrillation probe 100 and 2DC electrode group and regulation position (for example, the tube wall of Coronary vein, the inwall of right ventricle), therefore can carry out effective defibrillation therapy.
Apply energy (Step13) when (13) input is set defibrillation as the electric energy configuration switch 742 of external switch 74.
According to the supply unit 700 in the present embodiment, applying energy can set with the 1J scale between from 1J to 30J.
(14) input is as the built-in capacitance charging (Step14) to DC power supply unit 71 of the charge switch 743 of external switch 74.
(15) after charging finished, input applied switch 744(Step15 as the electric energy of external switch 74).
(16) when electric energy applies switch 744 input, by arithmetic processing section 75 contact of switching part 76 is switched to the 2nd contact, guaranteed to have cut off the path (Step16) that arrives ecg scanning instrument adapters 73 from probe adapter 72 via switching part 76 from the path of probe adapter 72 via switching part 76 arrival arithmetic processing section 75.
(17) after the contact of switching part 76 is switched to the 2nd contact, from accepting to apply polarity mutually different DC voltage (with reference to Step17, Figure 15 of Figure 11 C) to the 1DC electrode group of defibrillation probe 100 with 2DC electrode group via output circuit 751, switching part 76 and the probe adapter 72 of arithmetic processing section 75 from the DC power supply unit 71 of the control signal of arithmetic processing section 75.
Here, arithmetic processing section 75 is carried out calculation process and is transmitted control signal to DC power supply unit 71 so that with via the heart potential synchronous waveform of electrocardiogram input connector 77 input apply voltage.
Particularly, in the heart potential waveform of inputting one by one to arithmetic processing section 75 (from the part of 12 lead electrocardiogram of heart potential measuring unit 900), detect 1 R ripple (peak-peak), and obtain this peak height, then, begin to begin to apply through after the certain hour (for example, about 1/10 of the peak width of R ripple utmost point short time) in the moment of 80% the height (triggering level) that arrives this peak height from potential difference (when next R ripple rises).
Figure 16 is that expression utilizes defibrillation probe 100 in the present embodiment to give the regulation electric energy (figure of the potential waveform of measuring when for example setting output=10J).In the figure, the transverse axis express time, the longitudinal axis represents current potential.
At first, according to passing through later on certain hour (t so that the potential difference in the heart potential waveform of input arithmetic processing section 75 arrives triggering level 0) after, 1DC electrode group 31G becomes-utmost point, and 2DC electrode group 32G becomes+mode of the utmost point, and between applies DC voltage, and thus, electric energy is supplied to measures the current potential (V that rises 1It is the crest voltage of this moment.)。Passing through certain hour (t 1) after, according to so that 1DC electrode group 31G becomes+utmost point, 2DC electrode group 32G becomes-mode of the utmost point, between applies and reversed ± DC voltage, thus, electric energy is supplied to and measures the current potential (V that rises 2It is the crest voltage of this moment.)。
Here, from arriving triggering level to the time (t that begins to apply 0) be 0.01~0.05 second for example, it is 0.01 second that a preferred example is shown, time (t=t 1+ t 2) be 0.006~0.03 second for example, it is 0.02 second that a preferred example is shown.
Thus, can synchronously apply voltage with the heart potential waveform (being the R ripple of peak-peak) of input arithmetic processing section 75, can carry out effective defibrillation therapy.
Crest voltage (the V that measures 1) for example be 300~600V.
(18) potential difference in the heart potential waveform arrives triggering level and has passed through later on certain hour (t 0+ t) after, stop apply (Step18) from the voltage of DC power supply unit 71 thereby accept control signal from arithmetic processing section 75.
(19) after applying of voltage stops, the record that applies (the heart potential waveform during applying as shown in Figure 16) is shown in heart potential information display section 78(Step19).As displaying time, for example be between 5 seconds.
(20) arithmetic processing section 75 of supply unit 700 is when utilizing defibrillation probe 100 to carry out defibrillation, setting value (input value of energy settings switch 742), the output voltage (V of Figure 16 of the electric energy that obtain resistance value (the intracardiac resistance value of measuring first when carrying out defibrillation) between 1DC electrode group 31G and the 2DC electrode group 32G, will apply between 1DC electrode group 31G and 2DC electrode group 32G 1The shown actual voltage that applies) and the information of output time (the actual time that applies shown in the t of Figure 16), the sequence information (sequence information that memorizer 752 is stored) of these information and the moment of carrying out this defibrillation (moment of being determined by internal clocking 753) and supply unit 700 is written into event information storage part 113(in the memorizer 110 of defibrillation probe 100 in the lump with reference to Step20, Figure 17).
(21) contact of switching part 76 is switched to the 1st contact, recover via the path that switching part 76 arrives ecg scanning instrument adapters 73 from probe adapter 72, be input to ecg scanning instrument 800(with reference to Step21, Figure 13 from the heart potential information of the formation electrode of the 1DC electrode group 31G of defibrillation probe 100 and 2DC electrode group 32G).
(22) to the monitor that is shown in ecg scanning instrument 800, observe from the heart potential information (electrocardiogram) of the formation electrode (the formation electrode of 1DC electrode group 31G, 2DC electrode group 32G and base end side potential-measuring electrode group 33G) of defibrillation probe 100 and from the heart potential information (12 lead electrocardiogram) of heart potential measuring unit 900, " if normally " then finish, when " undesired (ventricle trembles and do not cure) ", return Step6(Step22).
Probe system according to present embodiment, utilize 1DC electrode group 31G and the 2DC electrode group 32G of defibrillation probe 100, can directly provide electric energy to the heart that has occured to tremble, sufficient electricity irritation (surge) that can defibrillation therapy is required only provides reliably to heart.
And, owing to can directly provide electric energy to heart, do not burn wound so can not produce at patient's body surface.
In addition, can record the resume of the event (measurement of the resistance value between defibrillation, electrode group, the again connection of supply unit) of defibrillation probe 100.
Thus, for example in use the defibrillation probe has occured when unusual, the event resume can be used for seeking the unusual reason that occurs.
And, the information that these events relate to is stored in the memorizer 110(event information storage part 113 of defibrillation probe 100), even therefore carry out the event of 1 defibrillation probe 100 with a plurality of supply units, the information that these events relate to can not be distributed to a plurality of supply units yet.Therefore, can carry out the management of event record information by the defibrillation probe 100 of being determined by sequence information.
In the probe system of present embodiment, the parts that relate to first link information and event record information and be arranged at defibrillation probe 100 only have memorizer 100(memory element), because the task of these information of processing is by arithmetic processing section 75 burdens of supply unit 700, so can not occuring, the defibrillation probe do not maximize, perhaps the situation of its complex structure.
In addition, the information that writes the memorizer 110 of defibrillation probe 100 can be read by suitable information read device.
According to the probe system of present embodiment, the defibrillation probe as disposable (Disposable) product only can be used within the time no problem from the viewpoint of its performance and safety.
In addition, because the connection that will write the first link information storage part 112 in the memorizer 110 of defibrillation probe 100 is constantly as the Fixed Initial Point of the use binding hours of defibrillation probe 100, even so identical or different supply units is connected again with defibrillation probe 100, when beginning through after the use binding hours from the connection moment (with the initial moment that connects of supply unit) that writes first link information storage part 112, when having carried out certain event by defibrillation probe 100, also make this defibrillation probe 100 not carry out next event.
In addition, consist of heart potential information that electrode 33 measures from probe adapter 72 not via switching part 76 but input to ecg scanning instrument 800 via ecg scanning instrument adapter 73 by base end side potential-measuring electrode group 33G, and, be connected with heart potential measuring unit 900 at this ecg scanning instrument 800, therefore even (switching part 76 is switched to the 2nd contact when ecg scanning instrument 800 can't be obtained defibrillation therapy from the heart potential of the 1DC electrode group 31G of defibrillation probe 100 and 2DC electrode group 32G, when being cut off from the path that probe adapter 72 arrives ecg scanning instrument adapters 73 via switching part 76), ecg scanning instrument 800 also can be obtained the heart potential information of being measured by base end side potential-measuring electrode group 33G and heart potential measuring unit 900, can monitor that at ecg scanning instrument 800 heart potential (supervision) is Yi Bian carry out defibrillation therapy on one side.
And, the arithmetic processing section 75 of supply unit 700 is carried out calculation process and is come DC power supply unit 71 is controlled, so that apply voltage (after the potential difference arrival triggering level in the heart potential waveform through beginning to apply behind the certain hour (for example 0.01 second)) with heart potential synchronous waveform ground via electrocardiogram input connector 77 input, can to the 1DC electrode group 31G of defibrillation probe 100 and 2DC electrode group 32G and heart potential synchronous waveform apply voltage, can carry out effective defibrillation therapy.
And, arithmetic processing section 75 is controlled to be when only the resistance value between the electrode group of defibrillation probe 100 does not surpass certain value, namely, the position of 1DC electrode group 31G and 2DC electrode group 32G and regulation (for example, the tube wall of Coronary vein, the inwall of right ventricle) fully during butt, just enters be used to the preparation that applies DC voltage, therefore can carry out effective defibrillation therapy.
In the probe system of present embodiment, the arithmetic processing section 75 of supply unit 700 also can have following function (intervalometer), namely, termly with reference to the moment shown in the internal clocking 753, constantly begin through after the memorizer 752 use binding hours of storing in the connection from the first link information storage part 112 of the memorizer 110 that writes defibrillation probe 100, be controlled to be and make defibrillation probe 100 not carry out event.
By also using intervalometer, for example in the time will passing through the use binding hours, undertaken after the event by defibrillation probe 100, even passed through at the state that is connected with supply unit 700 in the situation of long period, also can stop the execution of " next " event of this defibrillation probe 100.
