Abstract
The invention relates to the electrical connection technology field of , in particular to an internal connection line of a medical electronic instrument. The connection line is composed of an outer insulating layer, an outer shielding layer made by twining a PTFE film, conducting and signal wires coated with insulation layer and a filling wire. The conducting wire, the signal wire and the filling wire are arranged through the interior of the outer shielding layer; the outer surface of the outer shielding layer is coated with an outer insulating layer; the conducting wires coated with the insulating layer have two ones; the signal wires coated with the insulating layer have four ones, and the outsides of the four signal lines are provided with inner shielding layers made of a winding copper wire with a plated cover. The composite connection line has the properties of resistance to X-ray and to magnetic interference of electric wave, high sensibility, good stability and uniformity, nice flexibility, good flame retardance, good resistance to acid and alkali, and resistance to external pulling force, etc. Moreover, the composite connection line has gross structure with softness, small volume and is suitable for connection line used in interior of equipment.
Description
Technical field:
The present invention relates to medical instruments and equipment and be electrically connected technical field, particularly a kind of lines for medical electronic instrument internal connection.
Background technology:
Medical Devices are important tool of current diagnosis and treatment disease, it needs higher accuracy, sensitivity and stability, particularly when equipment need be used in place under some particular surroundingss, picture uses in the place that is subjected to X ray, magnetic or wave interference, or use shaken, under the tension, situation about being turned round, also or use, all need normal use in place near naked light, contact acid alkaloid substance.This is just all higher to the requirement of equipment various aspects, need use the accuracy of detection of the equipment that can both guarantee under various environment.The inside that is used in Medical Devices at present connects uses line, because defectiveness in the combination of the structure and material of line use and be subjected to environmental limitations, and comprehensive mechanical property is poor, interference free performance is poor.The good electric wire of some not affected by environment and anti-electromagnetic interference is not durable because comprehensive mechanical property is bad again.Particularly when the Medical Devices that are used for specific (special) requirements are electrically connected, might cause the connection status instability through long-term use, influence the normal operating conditions of instrument and equipment, diagnosis or medical treatment are caused harmful effect, for avoiding described phenomenon, flexibility, excellent flame-retardant performance, acid and alkali-resistance, the anti-external pull performance that this just needs a kind ofly have that opposing X ray and Electromagnetic Interference, sensitivity are higher, stability and uniformity are better, good is good etc. uses line being connected of performance.
Summary of the invention:
The objective of the invention is to provide a kind of lines for medical electronic instrument internal connection of performances such as having opposing X ray and Electromagnetic Interference, sensitivity is higher, stability and uniformity are better, good flexibility, excellent flame-retardant performance, acid and alkali-resistance, anti-external pull performance are good at the deficiencies in the prior art.
For achieving the above object, the present invention adopts following technical scheme:
A kind of lines for medical electronic instrument internal connection, outer shielding layer, the lead that is coating insulating barrier and holding wire, interstitial wire that it includes the insulation serving, is entwined by the PTFE film, wherein said lead, holding wire and interstitial wire are located in the inside of outer shielding layer, and the insulation serving then is arranged on the outer surface of outer shielding layer with the form that coats; The described lead that is coating insulating barrier is two; The described holding wire that is coating insulating barrier is four, also is provided with the internal shield that the copper cash of a coating is entwined outside four holding wires.
Described lead is bare copper wire or copper alloy wire.
Described four holding wires have two to be bare copper wire, and other two is copper alloy wire.
Described interstitial wire is shellproof yarn.
The described insulating barrier that is coating lead and holding wire is the fluorine material layer.
Described insulation serving is the TPE thermoplastic elastic material.
Beneficial effect of the present invention is: because the outer shielding layer of this connecting line is the PTFE plastic film, can resist X ray and magnetic, wave interference effectively; The transmission line group adopts the copper constantan combination, and thermo-electromotive force is bigger, and sensitivity is higher, and stability and uniformity are better; The lining material of serving is an environment friendly medical level TPE plastic cement, has good flexibility, anti-flammability, acid and alkali-resistance etc.; The ballistic resistant yams fiber that evenly is filled in inside of the present invention have stretching resistance strong, be easy to bending and stretch and draw and electric wire is not had damage, had effect the present invention of shellproof yarn to have good anti-external pull performance.Performances such as flexibility, excellent flame-retardant performance, acid and alkali-resistance, the anti-external pull performance that opposing X ray and Electromagnetic Interference, sensitivity are higher so the present invention has, stability and uniformity are better, good is good, and it is good that general structure shows as flexibility, and volume is little, is suitable for device interior connection line.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is a profile of the present invention
Embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing, see accompanying drawing 1,2, a kind of lines for medical electronic instrument internal connection, outer shielding layer 2, the lead 4 that is coating insulating barrier 7 and holding wire 5, interstitial wire 3 that it includes insulation serving 1, is entwined by the PTFE film, outer shielding layer 2 is the PTFE plastic film, can resist X ray and magnetic, wave interference effectively.Wherein said lead 4, holding wire 5 and interstitial wire 3 are located in the inside of outer shielding layer 2,1 outer surface that is arranged on outer shielding layer 2 with the form that coats of insulation serving, interstitial wire 3 is shellproof yarn, make stretching resistance of the present invention strong, be easy to bending and stretch and draw and electric wire is not had damage.The described lead 4 that is coating insulating barrier 7 is two bare copper wires or copper alloy wire.The holding wire 5 that is coating insulating barrier 7 is four, wherein there are two to be bare copper wire, other two is copper alloy wire, outside four holding wires 5, also be provided with the internal shield 6 that the copper cash of a coating is entwined, this copper constantan combination thermo-electromotive force is bigger, sensitivity is higher, and stability and uniformity are better and can resist X ray and electric wave, magnetic disturbance effectively.The described insulating barrier 7 that is coating lead 4 and holding wire 5 is environment-friendly type FEP polyfluorinated ethylene plastic layer, and material non-toxic can be recycled.Described insulation serving 1 is an environment friendly medical level TPE thermoplastic elastic material, and hardness is 60 degree, has good flexibility, anti-flammability, acid and alkali-resistance etc.Insulation serving 1 is made black, and the insulating barrier 7 of four holding wires 5 is made stamen redness, stamen white respectively, and the insulating barrier 7 of two leads 4 is made black and Lan Se respectively to show difference.The anti-external pull performance of general structure is good, and flexibility is good, and volume is little, is suitable for device interior connection line.
