As shown in Figure 1, cardiac diagnosis lead-line of the present invention, its core is that the human heart electric wave is transmitted to the electrocardio conductor 1 on electrocardiograph, this electrocardio conductor 1 is axle centered by line feeder 2, by many fine copper wires side by side by S just as the time spiral winding (also claiming oblique winding) on line feeder 2, form electrocardio conductor 1.
As shown in Figure 2, be covered with the propylene class insulating resin of hard on electrocardio conductor 1, and form electrocardio inductor 4.The line feeder 2 use fibers of this electrocardio inductor 4 twist into, more than Tensile strength can reach 20kg.Be wound in fine copper wire self softness on line feeder 2, can support to such an extent that live strong bending.Cardiac diagnosis lead-line needs directly with human body, to contact, so be not suitable for the harder electric wire of employing, and being configured on bending resistance curvature and stretching resistance of this fine copper wire has obvious advantage, but says and be used in that cardiac diagnosis lead is best suited for above.The present invention can adopt the fine copper wire of all size, such as the fine copper wire that adopts the standard that diameter is 0.1mm, by the fine copper wire spiral winding more than two or two on line feeder 2, this design no matter on bending resistance, tension or in the signal transmission, obviously is better than the single condctor that copper cash and fiber are wrapped up side by side.This design can adopt the copper cash of sizes, the diameter of copper cash can be between 0.05mm～1mm or larger size all can.
As shown in Figure 3, at electrocardio, induce in the manufacturing process of electric wire, electrocardio inductor 4 outsides are covered with to ethene carbon resin 5, with the electromagnetic wave of covering outer.Be wound around many copper cash with the S type simultaneously on the crust 5 of ethene carbon resin, form electromagnetic shield 6.Then be covered with soft insulation vinyl 7 in the outside of electromagnetic shield, electrocardio induces electric wire 8 just substantially to complete.This electrocardio is induced electric wire 8 to carry out two-layer electromagnetic shielding and is processed, so can accomplish not to be subject to the impact of external electromagnetic ripple fully.The copper cash that forms electromagnetic shield 6 is wound around with the S type, so greatly strengthened the anti-curved anti-advantage of pulling on.
As shown in Figure 4, induce the front end of electric wire 8 to peel the insulating resin crust of 25mm off electrocardio, remove electromagnetic shield 6 and conductive layer 5, expose electrocardio inductor 4.Peel the insulated hull of electrocardio inductor 4 off 15mm and expose electrocardio conductor 1.Electrocardio conductor 1 is inserted to pressing in mouth of human body splicing ear 9, as shown in Figure 5 that terminal and the upper and lower crimping of conductor is solid.
Use the resin of hard that the semi-finished product in the Fig. 5 connected are carried out to one-shot forming, make continue terminal 9 and electrocardio of human body induce electric wire 8 composition that is connected to be connected the cardiac diagnosis lead-line end 10 of human body.Then, use soft resin to carry out post forming to this end 10, the connecting portion of existing like this hard resin protection terminal 9 and electric wire 8, have again soft resin protection electric wire at an end of electric wire.And S also withstands alternating bending to the electrocardio conductor be wound around.Wherein, described one-shot forming, post forming are the technique of utilizing resin (comprising hard resin and soft resin) to be applied parts, and moulding is called as one-shot forming first usually, then by that analogy.Fig. 6 be in crimping human body splicing ear 9 and induce electric wire 8 through the electrocardio after twice moulding.
As shown in Figure 7, before the electrocardio conductor 1 by bosom carries out crimping with human body splicing ear 9, first the electrocardio conductor is made a call to a knot 18, then will be carried out crimping with terminal as shown in Figure 5 with knot 18 electrocardio conductor 1, use as shown in Figure 6 hard, soft insulating resin moulding.Like this, even electrocardio induces electric wire 8 to be subject to strong pullling from both direction, and the situation that also not there will be broken string, comes off by alternating bending.If human body splicing ear 9 and electrocardio conductor 1 fully do not connect, because the situation that terminal 9 and electrocardio conductor 1 are separated can not occur middle this knot 18 yet.In addition because this knot existence of 18, though crooked or pull electrocardio and induce electric wire frequently, other connecting portion situation such as also can not come off.
Fig. 8 has showed the relaying position that electrocardio induces electric wire 8 to be connected and to form with a wire terminations 14 of a resistance 11 and circular multiple core cord 13.By the connection shown in Fig. 6 the electrocardio of human body splicing ear 9 induce electromagnetic shield 6, ethene carbon resin layer 5 and the insulating resin layer of the other end end of electric wire 8 to remove, then utilize the resistance 11 phase crimping that crimp type terminal A12 is 35K Ω by electrocardio conductor 1 and resistance.And at the opposite side of resistance, via crimp type terminal B15 by each wire terminations 14 of the circular electromagnetic shielding line 13 of multicore respectively with its crimping, form the relay connection section formed by crimp type terminal A12, resistance 11, crimp type terminal B15.The circular electromagnetic shielding line of 10 cores of commonly using of take is example, and required resistance 11 and electrocardio induce electric wire 8 quantity to be 10, form 10 relay connection sections.
The resistance of relay, be to use AED to carry out moment during up to the defibrillation of 5000V high pressure at the human heart all standing, or while using the occasion such as the electric scalpel of high frequency waves, in order to stop high-tension electricity, lead to electrocardiograph setting.
Then also need each relay connection section mutually insulated, and the relay connection section of mutually insulated is carried out to shielding processing.For the situation of 10 relay connection sections, adopt the rectangular fixed head 21 with 10 grooves 20, but fixed head 21 single faces also can be two-sided with 10 grooves with 10 grooves, what Fig. 9 provided is the situation of single face with 6 grooves.The relay connection section that Fig. 8 is described puts into groove 20 and guarantees to insulate and fix.Induce electric wire to put into respectively in the groove of fixed head upper and lower surface 10 radical center electricity, the 6 radical center electricity that connect chest in 21 li assemblings of groove of the wherein one side of fixed head are induced the relay connection section of electric wire 8 fixing, at 4 radical center electricity of 21 li assembly and connection foots of groove of another side, hand, induce the relay connection section of electric wire fixing.The fixed head assembled is covered to upper and lower cover plates 22.Namely the relay connection section shown in Fig. 8 is assembled in fixed head, covers cover plate 22 and form the relaying inner box that relay connection is housed.
