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 the electrocardiograph; This electrocardio conductor 1 is to be central shaft with line feeder 2, with many fine copper wires side by side by S just as the time spiral twine (also claiming oblique winding) on line feeder 2, form electrocardio conductor 1.
As shown in Figure 2, on electrocardio conductor 1, be covered with the propylene class insulating resin of hard, and form electrocardio inductor 4.The line feeder 2 usefulness fibers of this electrocardio inductor 4 twist into, and stretching resistance intensity can reach more than the 20kg.Be wound in fine copper wire self softness on the line feeder 2, can support to such an extent that live strong bending.Cardiac diagnosis lead-line needs directly to contact with human body, so be not suitable for adopting harder electric wire, and being configured in of this fine copper wire all has remarkable advantages on bending resistance curvature and the stretching resistance, but says to be used in and be best suited for above the cardiac diagnosis lead.The present invention can adopt the fine copper wire of all size; Such as adopting diameter is the fine copper wire of the standard of 0.1mm; Fine copper wire spiral more than two or two is wound on the line feeder 2; This design no matter on bending resistance, the tension still in the signal transmission, obviously be superior to the single condctor that copper cash and fiber are wrapped up side by side.This design can be adopted the copper cash of multiple size, the diameter of copper cash can be between 0.05mm～1mm or bigger size all can.
As shown in Figure 3, induce in the manufacturing process of electric wire at electrocardio, electrocardio inductor 4 outsides are covered with ethene carbon resin 5, with the electromagnetic wave of covering outer.On the crust 5 of ethene carbon resin, twine many copper cash simultaneously, constitute electromagnetic shield 6 with the S type.Be covered with soft insulation vinyl 7 then in the outside of electromagnetic shield, electrocardio induces electric wire 8 just to accomplish basically.This electrocardio is induced electric wire 8 to carry out two-layer electromagnetic shielding and is handled, so can accomplish not receive the influence of external electromagnetic ripple fully.The copper cash that constitutes electromagnetic shield 6 twines 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 pressing in the mouth of human body splicing ear 9, as shown in Figure 5 that crimping about terminal and the conductor is solid.
Use the resin of hard that the semi-finished product among the Fig. 5 that connects are carried out one-shot forming, make the human body terminal 9 that continues induce electric wire 8 to fuse with electrocardio to form the cardiac diagnosis lead-line end 10 that is connected human body.Then, use soft resin that this end 10 is carried out post forming, existing like this hard resin is protected the connecting portion of terminal 9 and electric wire 8, and the resin protection electric wire of softness is arranged again at an end of electric wire.And S also withstands alternating bending to the electrocardio conductor that twines.Wherein, described one-shot forming, post forming are to utilize resin (comprising hard resin and soft resin) to the technology that parts apply, moulding is called as one-shot forming first usually, then by that analogy.Fig. 6 be in the 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 with the bosom carries out crimping with human body splicing ear 9; Earlier the electrocardio conductor is made a call to a knot 18, will carry out crimping with terminal with the electrocardio conductor of knot 18 1 is as shown in Figure 5 then, use hard as shown in Figure 6, soft insulating resin moulding.Like this, even electrocardio induces electric wire 8 to receive strong pullling from both direction, and the situation that breaks, come off can not appearred by alternating bending yet.If human body splicing ear 9 does not fully connect with electrocardio conductor 1, because the situation that terminal 9 and electrocardio conductor 1 are separated can not take place middle this knot 18 yet.In addition because this knot existence of 18, though frequent crooked or pull electrocardio and induce electric wire, other connecting portion situation such as also can not come off.
Fig. 8 has showed the relaying position that electrocardio induces an electric wire 8 and a wire terminations 14 of resistance 11 and circular multiple core cord 13 to be connected and to form.With the connection shown in Fig. 6 the electrocardio of human body splicing ear 9 induce terminal electromagnetic shield 6, ethene carbon resin layer 5 and the insulating resin layer of electric wire 8 other ends to remove, utilize crimp type terminal A12 with electrocardio conductor 1 and the resistance 11 mutually crimping of resistance then for 35K Ω.And at the opposite side of resistance, via crimp type terminal B15 with each wire terminations 14 of the circular electromagnetic shielding line 13 of multicore respectively with its crimping, form the relaying connecting portion of forming by crimp type terminal A12, resistance 11, crimp type terminal B15.With the circular electromagnetic shielding line of 10 cores commonly used is example, and then required resistance 11 induces electric wire 8 quantity to be 10 with electrocardio, forms 10 relaying connecting portions.
The resistance of relay is to use AED to carry out moment during up to the defibrillation of 5000V high pressure at the human heart all standing, perhaps uses the electric scalpel of high frequency waves etc. fashionable, leads to electrocardiograph setting in order to stop high-tension electricity.
Also need then, and the relaying connecting portion of mutually insulated is carried out shielding processing each relaying connecting portion mutually insulated.For the situation of 10 relaying connecting portions, adopt the rectangular fixed head 21 that has 10 grooves 20, but having 10 grooves, fixed head 21 single faces also can two-sidedly have 10 grooves, what Fig. 9 provided is the situation that single face has 6 grooves.The relaying connecting portion of Fig. 8 description is put into groove 20 guarantee insulation and fixing.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 in 21 li assemblings of groove of the wherein one side of fixed head, connect chest are induced the relaying connecting portion of electric wire 8 and fixing, and the 4 radical center electricity that connect foot, hand in 21 li assemblings of groove of another side are induced the relaying connecting portion of electric wire and fixing.The fixed head that assembles is covered cover plate 22 up and down.Just relaying connecting portion shown in Figure 8 is assembled in the fixed head, covers cover plate 22 and form the relaying inner box that the relaying connection is housed.
Metal clad plate, metal tape, metal forming etc. in the outside of relaying inner box, to shield extraneous obstacle electromagnetic wave, naturally, shield is wanted ground connection (this omits diagram); In packing the relaying inner box into relaying box 16 shown in figure 10 then, promptly accomplish processing to relay.
Shown in figure 10, at the opposite side of the circular electric wire 13 of 10 cores the plug 24 that is connected with electrocardiograph is installed, this plug is the joint of 10P, transmits the electrocardio ripple of human body to electrocardiograph through it; Perhaps adopt USB plug, upload the electrocardio ripple of the body of making a gift to someone to PC with electrocardiograph function through it.The electromagnetic wave influence that electrocardio induces electric wire to shield fully to transmit in the external world, but electrocardio induce electric wire and the circular electric wire of 10 cores in the process of operating since can be bent mobile, so electric wire self can generate electromagnetic waves.For the electromagnetic wave that electric wire self is produced is removed, annular magnetosphere 15 is installed in the position near plug 24 of the circular electric wire 13 of 10 cores.Then, with insulating resin molding plug is fixed again.
Between electrocardio conductor 1 and multicore electromagnetic shielding line 13, be provided with signal amplifier and A/D converter successively; Amplifier can adopt existing operational amplifier; Can be with being enlarged into the electric current of the three ten-day period of hot season through 10 operational amplifiers from the weak current of 10 electrodes output, A/D converter can be converted into digital signal by the electrocardiosignal that amplifier amplifies.Being sent to electrocardiograph by the digital signal after the conversion perhaps is sent on the PC with electrocardiograph function through USB plug.The PC that electrocardiograph perhaps has the electrocardiograph function makes electrocardiogram based on these digital signals.Use the feasible PC of USB plug also can make electrocardiogram at an easy rate through usual use.
Shown in figure 10, indicator light 23 is set on relaying box 16, when human body splicing ear 9 contacts with the patient well, when the electrocardio wave energy of human body enough normally was sent to cardiograph, the indicator light 23 of relay will be lighted.If loose contact, indicator light will extinguish.If human body splicing ear 9, electrocardio are induced the each several part loose contact of electric wire 8, resistance 11, circular 10 core electric wires 13, plug 24, indicator light 23 also can extinguish.Just can confirm through the warning of indicator light 23 whether the electrocardio ripple normally is sent to cardiograph.
More than explanation, through this technological means, the human heart electric wave can guarantee to be sent to accurately above the cardiograph, has solved because of the inaccurate problem that does not cause mistaken diagnosis of heart electric wave.
