The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, multifunctional respiration signal detecting catheter 18 described in the utility model is made up of 10 the identical electrode 1-10 of length, sacculus 22, far-end macropore 14 and catheter proximal end joints.Sacculus 22 far-ends and respiration signal detecting catheter 18 have a sacculus far-end junction 16, and balloon proximal and respiration signal detecting catheter 18 have a balloon proximal junction 17.One distance 15 is arranged between sacculus 22 and the electrode 10.

As shown in Figure 2, multifunctional respiration 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 electrode cable tubule chamber 20 that power supply polar conductor 24 passes.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 chamber 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 10 is used for ground connection as the reference electrode, and all the other 9 is recording electrode 1-9.One distance 15 is arranged between proximal electrode and the sacculus.A gap 11 is arranged between proximal electrode 10 and the near-end recording 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 electrode cable 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 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 signal detecting catheter are between the 5-10cm, and girth is about the gap 15 that a 1cm is arranged between 2cm. sacculus 22 and the proximal electrode 10.Each electrode length is 1cm, and gap 11 is 2cm between reference electrode 10 and the recording electrode 9, and the gap 12 between the adjacent recording electrode 1-9 is below the 1mm.Nine recording electrodes are formed five and led: leads I is made up of electrode 1 and electrode 5, and 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, and the V that leads is made up of electrode 5 and electrode 9.Each two distance between electrodes of leading is 3.4cm.When placing electrode, each diaphram myoelectric amplitude that leads and write down of Real Time Observation, 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 target 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, diaphram moves less than 1.5cm, and the gap of 1mm is only arranged between the adjacent recording electrode, thus if recording electrode 5 is placed in the diaphragmatic level of esophagus, much no matter amplitude of respiration has, 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 macropore 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.
