The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, multifunctional respiration cardiac electricity signal detecting catheter 18 of the present invention is made up of 11 identical electrode 1-10 of length and 31, sacculus 22, far-end macropore 14 and catheter proximal end joint.Sacculus 22 far-ends and multifunctional respiration cardiac electricity signal detecting catheter 18 have a sacculus far-end junction 16, and sacculus 22 near-ends and multifunctional respiration cardiac electricity signal detecting catheter 18 have a balloon proximal junction 17.One distance 15 is arranged between sacculus 22 and the electrode 10.Electrode 31 and sacculus 22 have a gap 32.
As shown in Figure 2, multifunctional respiration cardiac electricity signal detecting catheter 18 is made up of three not connected tube chambers.One is for measuring the tubule chamber 19 that esophagus is pressed in the conduit.Esophagus presses tubule chamber 19 to communicate with sacculus 22, and another is the tubule chamber 20 that power supply polar conductor 24 passes, and another is the big tube chamber 21 of nasal feeding.The big tube chamber 21 of nasal feeding communicates with the macropore 14 of far-end, is used for nasal feeding.
As shown in Figure 3, sacculus 22 presses the aperture 23 on the tubule chamber 19 to communicate with tubule 19 by measuring esophagus, and the tubule chamber 19 of measuring the esophagus pressure joins by bifurcated 26 and tee T union joint 30 again, presses thereby measure sacculus.Proximal electrode 31 is used for ground connection as the reference electrode, and all the other 10 is recording electrode 1-10.One distance 15 is arranged between electrocardioelectrode 10 and the sacculus.A gap 11 is arranged between electrocardioelectrode 10 and the electrode 9.Small clearance for insulation 12 is arranged between the recording electrode.Recording electrode 1 has a distance 13 with the far-end macropore 14 of conduit.Each electrode respectively with tubule chamber 20 in lead 24 join, and extend to the terminal 28 of catheter proximal end, thereby derive the diaphragm muscle signal of telecommunication by bifurcated 25.The far-end of multifunctional respiration cardiac electricity signal detecting catheter has a plurality of macropores 14, communicates with the big tube chamber 21 of nasal feeding in the conduit, and joins by conduit bifurcated 27 and stomach tube joint 29, is used for nasal feeding.
As shown in Figure 4, as preferred embodiment, sacculus 22 length of multifunctional respiration cardiac electricity signal detecting catheter are that girth is about 3cm between the 5-10cm.Gap 15 between sacculus 22 and the electrode 10 is 1cm.Gap 32 between sacculus 22 and the electrode 31 is 1cm.Each electrode length is 1cm, and gap 11 is 2cm between electrocardioelectrode 10 and the diaphram electromyographic electrode 9, and the adjacent segment 12 between the electrode 1-9 is about 1mm.Ten recording electrodes are formed six and led: leads I is made up of electrode 1 and electrode 5, leads I I is made up of electrode 2 and electrode 6, and leads I II is made up of electrode 3 and electrode 7, and leads I V is made up of electrode 4 and electrode 8, the V that leads is made up of electrode 5 and electrode 9, and the VI that leads is made up of electrode 9 and electrode 10.Leads I-V is used to write down the diaphram myoelectricity, two about 3.4cm of distance between electrodes that each leads.The VI that leads is used to write down the esophagus electrocardiogram, and two distance between electrodes are 2cm.When placing electrode, the diaphram myoelectric amplitude that Real Time Observation leads I-V is write down, to record amplitude similar and during than the big signal of other signal amplitude of writing down of leading as leads I and the V that leads, and pointing out electrode 5 is diaphragmatic level at esophagus.At this moment leads I II is because two electrodes equate that with the diaphram distance current potential is offset, and only records a very little diaphragm muscle signal of telecommunication about it.Because during the maximum breathing motion, the esophageal displacement of diaphram is moving less than 1.5cm, and the gap of 1mm is only arranged between the adjacent recording electrode, so if recording electrode 5 is placed in the diaphragmatic level of esophagus, no matter amplitude of respiration has much, there is an electrode to be in diaphragmatic level all the time.For example, lung capacity increase or diaphram shrink and cause diaphram to move down 1cm when air-breathing, and originally the electrode 5 in diaphragmatic level leaves diaphram, and at this moment 6 of recording electrodes become in the diaphragmatic level of esophagus.By in 5 are led, dynamically selecting maximum diaphram myoelectricity, just look like to have an electrode to move following diaphram all the time.So just in diaphragm muscle electrographic recording process, eliminated respiratory movement or diaphram moves the interference that is caused.Because the diaphram plane of esophagus is from cardia 2-3cm, when electrode 5 is in the diaphram plane of esophagus, distal end of catheter aperture 14 under one's belt, the stomach tube joint by near-end can carry out nasal feeding smoothly.At this moment sacculus 22 hypomere in esophagus can be measured esophagus and presses, and can be used for trigger breathing machine and supply gas.
