The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, diaphragmatic function detected catheter described in the utility model is made up of conduit 11, proximal balloon 12, distal balloon catheter 13 and 10 identical electrode 1-10 of length.Be separated by by 10 electrodes between proximal balloon 12 and the distal balloon catheter 13.Distal balloon catheter 13 invests the end of conduit 11.Proximal electrode 10 is used for ground connection as the reference electrode, and all the other 9 is recording electrode 1-9.Distance between proximal electrode and the proximal balloon is 1cm.Distance between proximal electrode and the recording electrode gone up most is 2cm.Clearance for insulation between the recording electrode is 0.05cm..Recording electrode and the distance between the distal balloon catheter are 2cm.
Long 10 centimetres of proximal balloon, 2.04 centimetres of girths, be positioned at the head end of detected catheter and communicate by a plurality of apertures 21 with the conduit tube chamber: distal balloon catheter 13 long 5.2 centimetres, 2.04 centimetres of girths are positioned at the terminal of diaphragmatic function detected catheter and communicate by a plurality of apertures 20 with the conduit tube chamber.Proximal electrode 10 and recording electrode 1-9 equal in length.Proximal electrode 10 is used for ground connection as the reference electrode.All the other 9 adjacent recording electrodes are sequentially arranged one by one, keep a small clearance for insulation 15 mutually.9 recording electrodes are formed 5 records and are led, and all have three electrodes to be separated by between each two recording electrode that lead.In 9 recording electrodes, being arranged in intermediary electrode is two common electrodes of leading.
Leads I is made up of recording electrode 1 and recording electrode 5, leads I I is made up of recording electrode 2 and recording electrode 6, leads I 11 is made up of recording electrode 3 and recording electrode 7, and leads I V is made up of recording electrode 4 and recording electrode 8, and the V that leads is made up of recording electrode 5 and recording electrode 9.
As preferred embodiment, the parameter of this diaphragmatic function detected catheter is: two sacculus that material is identical, proximal balloon 12 long 10cm, girth 2.04cm.The gap 17 that an Icm is arranged between proximal balloon 12 and the proximal electrode 10.Distal balloon catheter 13 long 5.2cm, girth 2.04cm the terminal of conduit and and far-end recording electrode 9 between the gap 14 of a 2cm is arranged.Each electrode length is Icm, and gap 16 is 2cm between reference electrode 10 and the recording electrode 1, and the gap 15 between the adjacent recording electrode 1-9 is 0.05cm.Each two distance between electrodes of leading is 3.2cm.When placing electrode, each diaphram myoelectric amplitude that leads and write down of Real Time Observation, when lead 1 and the V that leads to record amplitude similar and during than the big signal of other signal amplitude of writing down of leading, pointing out target 5 is diaphragmatic level at esophagus.At this moment leads I 11 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 0.05cm is only arranged between the adjacent recording electrode, so if the intermediate record electrode 5 of recording electrode 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 balloon catheter 13 under one's belt, proximal balloon 12 is just at esophagus.
As shown in Figure 2, proximal balloon 12 is positioned at the head end of diaphragmatic function detected catheter and communicates with conduit tube chamber 18 by a plurality of apertures 21.Distal balloon catheter 13 is positioned at the terminal of diaphragmatic function detected catheter and communicates with conduit tube chamber 19 by a plurality of apertures 20.Lead and 1 be made up of electrode 1 and electrode 5, lead and 11 be made up of electrode 2 and electrode 6, leads I 11 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.
