Description
Technical field
The utility model relates to a kind of communications field, specifically a kind of medical cable.
Background technology
Medical cable is mainly used in, into Medical Instruments carry high frequency digital signal, having the following disadvantages at present:
1, medical cable generally adopts the mode transfer signal of 2 core+3 cores, and the continuous progress of science and technology makes the performance of Medical Instruments progressively promote, and current signal transmission pathway cannot meet the demand that device upgrade is regenerated;
2, the ground connection copper cash (being arranged in order wire) in medical cable easily produces interference to adjacent wires, and the tensile strength of this ground connection copper cash is lower, easily ruptures after using a period of time.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, and provide a kind of medical equipment high-frequency transmission cable, this cable should have the feature that signal transmission pathway is wide, signal disturbing is little, tensile strength is high.
The technical solution of the utility model is: a kind of medical equipment high-frequency transmission cable, comprises inner sandwich layer, outer shielding layer, waterstop and oversheath from inside to outside successively; Described inner sandwich layer comprises two strands of gasket for packings, some outer conductors and holding wire; Shown holding wire comprises two wires, screen and sheaths; It is characterized in that: described earth connection comprises inner wire and inner sheath for eliminating the earth connection of static electricity on human body to be also provided with two in the screen of described holding wire, described inner wire is that conduction PVC makes.
The quantity of described outer conductor is four.
Described outer shielding layer and screen are metal mesh shield layer.
The beneficial effects of the utility model are:
1, in order wire, arrange that two earth connections are for eliminating static electricity on human body, ground connection copper cash (existing ground connection copper cash is not easily bending and tensile strength is poor) simultaneously in cancelling signal line, adjacent wires not only can be avoided to be interfered (static electricity on human body's generation current is less can not produce interference signal), can prevent again static electricity on human body from damaging Medical Instruments, the circularity of holding wire can also be improved simultaneously;
2, an outer conductor (being provided with three outer conductors in prior art) is arranged again, this outer conductor not only can be used for signal transmission but also can be used for using as earth connection, thus add signal path, the upgrading of Medical Instruments can be adapted to, meet consumers' demand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cross section.
Fig. 2 is the structure for amplifying schematic diagram of holding wire cross section in the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of medical equipment high-frequency transmission cable, comprises inner sandwich layer, outer shielding layer 31, waterstop 32 and oversheath 33 from inside to outside successively.
Described inner sandwich layer comprises two strands of gasket for packings 21, some outer conductors 22 and holding wire 4; Described outer conductor is for connecting the instruments such as BOLD contrast, B ultrasonic, electrocardiogram, electroencephalogram (EEG), and its quantity is four; Not only the outer conductor set up can be used for signal transmission but also can be used as earth connection use (substituting original ground connection copper cash); Described gasket for packing is nylon yarn and density is 3000-5000D (preferred 4000D).
Described holding wire comprises two wires 11, two earth connections, screen 12 and sheaths 13; Wherein, described earth connection comprises inner wire 41 for eliminating static electricity on human body and coated inner sheath 42 in the conductor, and inner wire is made (conduction PVC buyable obtains) for conduction PVC.Described screen and sheath are coated on wire from inside to outside successively and earth connection is outside.
Described outer conductor and wire are generally single core tinned wird and outside is all coated with insulating sleeve (omitting concrete structure in figure).Described outer shielding layer, screen are generally metal mesh shield layer.Described outer shielding layer, waterstop and oversheath are coated on inner sandwich layer from inside to outside successively.
Claims (3)
1. a medical equipment high-frequency transmission cable, comprises inner sandwich layer, outer shielding layer (31), waterstop (32) and oversheath (33) from inside to outside successively; Described inner sandwich layer comprises two bursts of gasket for packings (21), some outer conductors (22) and holding wire (4); Shown holding wire comprises two wires (11), screen (12) and sheath (13); It is characterized in that: be also provided with two in the screen of described holding wire for eliminating the earth connection of static electricity on human body, described earth connection comprises inner wire (41) and inner sheath (42), and described inner wire is that conduction PVC makes.
2. a kind of medical equipment high-frequency transmission cable according to claim 1, is characterized in that: the quantity of described outer conductor is four.
