Abstract
A medical high strength bending resistant cable provided by the utility model comprises conductors, a peripheral core wire, an outer shielding layer used for wrapping the conductors and the peripheral core wire, and an outer insulating layer used for wrapping the outer shielding layer, wherein each conductor comprises at least two conducting wires, inner insulating layers used for wrapping the conducting wires respectively, an inner shielding layer used for wrapping the inner insulating layers and an inner sheath used for wrapping the inner shielding layer; the peripheral core wire comprises at least two core wires, insulating layer used for wrapping the core wires respectively and a sheath used for wrapping the insulating layer; fillers are filled in the gaps between the outer shielding layer and the conductors and between the outer shielding layer and the peripheral core wire. By the structure improvement, the medical high strength bending resistant cable of the utility model enables the strength to be improved effectively and the insulating tensile strength to be increased, is not fatigued after being bent and stretched many times, and has a good insulating effect.
Description
Technical field
The utility model relates to a kind of for Medical Devices inside or outside cable.
Background technology
Medical Devices instrument cable used may be used to provide electric current, data-signal or have both two kinds of functions simultaneously.The cable that Medical Devices are used must keep consistency and reliability in the extremely wide environment of scope, all must consider mechanicalness, as pliability, resistance to extruding or tensile strength etc. during every kind of cable design.Adopt tough and tensile material can protect the conductor in cable to be difficult for being fractureed.Due to the particularity of medical instruments and equipment environment of living in, need to adapt to its different purposes and improve material and the structure of cable; Under environment as high in ionising radiations such as X-ray film making, CT film makings, the cable that equipment is used requires shield effectiveness superior, and anti-external interference ability is strong; And as the stube cable of Gastrointestinal Endoscopes, need to disinfect, so cable is difficult for being sterilized liquid and corrodes, and also to its pliability, requires very high simultaneously.Therefore, the Medical Devices transmission cable of highly-specialised should possess the superperformances such as safety, stable, tension.Existing normal cable is generally comprised of insulation sheath clad metal core, and its shield effectiveness and bad mechanical strength, easily cause the aging breakage of external insulation sheath, also has the defects such as bending performance is poor, useful life is short simultaneously.
Summary of the invention
Main purpose of the present utility model is to overcome that existing cable shield is poor, bad mechanical property, the poor shortcoming of bending performance, pass through structural improvement, effectively improved the intensity of cable, increased insulation tensile strength, make cable repeatedly bend and stretch after there will not be fatigue, there is good insulation effect.
The technical solution adopted in the utility model is: the resistance to bending cable of a kind of medical high strength, comprise conductor, peripheral heart yearn, for the outer shielding layer of coated this conductor and this periphery heart yearn and for being coated the external insulation layer of this outer shielding layer, wherein, this conductor comprises at least two wires, inner insulating layer for coated each root wire, for the internal shield of coated this inner insulating layer and for being coated the inner sheath of this internal shield, this periphery heart yearn comprises at least two heart yearns, for the insulating barrier of coated each root heart yearn and for being coated the sheath of this insulating barrier, this outer shielding layer and this conductor, gap between this periphery heart yearn is filled with filler.
This wire is zinc-plated alloyed copper wire.
This inner insulating layer adopts PE layer.
This external insulation layer is PVC layer.
This internal shield and this outer shielding layer are tinned copper braid.
The beneficial effects of the utility model are: the utility model structurally comprises conductor, peripheral heart yearn, for the outer shielding layer of coated this conductor and this periphery heart yearn and for being coated the external insulation layer of this outer shielding layer, wherein, this conductor comprises at least two wires, inner insulating layer for coated each root wire, for the internal shield of coated this inner insulating layer and for being coated the inner sheath of this internal shield, this periphery heart yearn comprises at least two heart yearns, for the insulating barrier of coated each root heart yearn and for being coated the sheath of this insulating barrier, this outer shielding layer and this conductor, gap between this periphery heart yearn is filled with filler.The utility model by structural improvement, has improved the intensity of cable effectively, has increased insulation tensile strength, make cable repeatedly bend and stretch after there will not be fatigue, there is good insulation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
