Technical solution of the present invention is as follows: a kind of medical electrode conduit, including reference electrode, body, impedance ring, antimony electrode and adapter, the front end of described body is connected with reference electrode, rear end is connected with adapter, it is characterized in that: on described body, be installed with impedance ring and antimony electrode retainer ring, antimony electrode retainer ring arranges antimony electrode；Described body is multi-lumen tube, has multiple mutually isolated tract, is all equipped with copper conductor in each tract.
Further, tract in described body is divided into first tract the same number of with reference electrode, second tract the same number of with impedance ring and threeth tract the same number of with antimony electrode, first tract wears the first copper conductor, the front end of this first copper conductor is connected with reference electrode, the rear end of the first copper conductor is connected with adapter, described second tract wears the second copper conductor, the front end of the second copper conductor passes from the through hole tube body wall, and connect with corresponding impedance ring, the rear end of the second copper conductor is connected with adapter, described 3rd tract wears the 3rd copper conductor, the front end of the 3rd copper conductor is connected with antimony electrode, the rear end of the 3rd copper conductor is connected with adapter.
Adopt above technical scheme, body is a kind of multi-lumen tube structure, impedance ring and antimony electrode Fixing shrink ring are outside multi-lumen tube, copper conductor is through in independent tract respectively, it is isolated from each other between copper conductor, the risk loosely easily leaked because of viscose glue when so efficiently solving background technology every section series connection, also improves the structural strength of whole electrode catheter simultaneously；Copper conductor is separated in independent tract by multi-lumen tube, it is to avoid the risk of copper conductor adhesion short circuit.Meanwhile, The present invention reduces technological process, reduce production cost, improve product yields, improve production efficiency.
Described body and copper conductor, by one-body molded, so solve the problem that background technology threading is difficult.
The front end of described second copper conductor is spirally wound on body, and with impedance ring tight fit.The front end of above structure the second copper conductor is connected firmly on body, and the good reliability that the second copper conductor turns on impedance ring.
In order to simplify assembling, it is ensured that the fixing that impedance ring is installed, the rear and front end of described impedance ring is placed on body admittedly by closing up.
In order to simplify structure, it is simple to install, described antimony electrode is arranged on antimony electrode retainer ring and body in the corresponding hole, location offered, and antimony electrode and the 3rd copper conductor weld mutually, and antimony electrode is connected by viscose glue is fixing with body and antimony electrode retainer ring.
In order to simplify structure, convenient for assembly, it is ensured that the fixing that antimony electrode retainer ring is installed, the rear and front end of described antimony electrode retainer ring is placed on body admittedly by closing up.
In order to make reference electrode engage closely with body, it is firm to connect, and described reference electrode and the first copper conductor weld, and the rear end of reference electrode is inserted in the front port of body, and both are fixed by viscose glue.
The invention has the beneficial effects as follows:
1) impedance ring, antimony electrode Fixing shrink ring are loaded on outside body, the risk loosely easily leaked because of viscose glue when solving tradition every section series connection, also improve the structural strength of whole electrode catheter simultaneously.
2) multi-lumen tube and copper conductor change one-shot forming into, the problem solving tradition threading difficulty.
3) copper conductor is separated in independent tract by multi-lumen tube, it is to avoid the risk of copper conductor adhesion short circuit.
4) reduce technological process, reduce production cost, improve product yields, improve production efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present embodiment is made up of reference electrode 1, body 2, impedance ring 3, antimony electrode retainer ring 4, antimony electrode 5, copper conductor and adapter 7 etc..The present embodiment is to configure according to the structure of a reference electrode, eight impedance rings, an antimony electrode, impedance ring, antimony electrode, antimony electrode retainer ring, the quantity of copper conductor, order and distance can be changed adjustment according to different demands by this structure accordingly, meet various demand.
Annexation between the present embodiment parts is: the rear end of reference electrode 1 is inserted in the front port of body 2, and both are fixed by viscose glue, and the rear end of body 2 is connected with adapter 7.Setting gradually eight impedance rings 3 on body 2 from front to back, each impedance ring 3 is all set on body 2, and the rear and front end of impedance ring 3, by closing up to body 2 crimp, makes impedance ring 3 admittedly be placed on body 2.Arranging antimony electrode retainer ring 4 between two impedance rings 3 wherein, antimony electrode retainer ring 4 is set on body 2, and the rear and front end of antimony electrode retainer ring 4, by closing up to body 2 crimp, makes antimony electrode retainer ring 4 admittedly be placed on body 2.
