Description
Technical field
The present invention relates to a kind of cable making method, relate in particular to a kind of cable making method for medical device.
Background technology
Electric wire has been widely used in the detection of medical treatment, industrial production, communications and transportation, architectural engineering and facility, modern agriculture and scientific research, engineer equipment or military installations, space, ocean at present, and has reached ubiquitous state.Along with socioeconomic activity description is carried out the development of step great-jump-forward from the degree of depth to the range, the electric wire kind is brought in constant renewal in and is perfect, and output continues to increase.For example, implement the cable that the transmission signals of the used Medical Devices of highly difficult operation was saved and carried out to open-air malpractice; Building the high-intelligentization building needs for hundreds of, thousands of computer network cable that electronic computer divides cascade network to use; Build the public cable television network in city, the whole city and even all banks of the whole nation banking procedure where deposits and withdrawals are processed at any branch bank, carry out online economic interaction and information interchange etc. and must install the broad band cable net that high reliability transport is used; Realize that the emission of military artillery or antiaircraft artillery group remote control procedure need design the control cable that is fit to field extreme environment.
The application of electric wire mainly is divided into three major types: electric power system, the information transmission system and engineering equipment and instrument and meter system.The electric wire product that electric power system adopts mainly contains built on stilts bare wire, bus-bar (bus), power cable, rubber cover cable, aerial insulated cable), branch cable (replacing the part bus), electromagnetic wire and power equipment be with the electrical equipment electric wire etc.The electric wire that is used for the information transmission system mainly contains local cable, camera cable, electronic cable, radio frequency cable, fiber optic cable, data cable, electromagnetic wire, power communication or other composite cables etc.In engineering equipment, the instrument and meter system except that built on stilts bare wire almost other all products application is all arranged, but mainly be power cable, electromagnetic wire, data cable, instrument and meter cable etc., cable for medical apparatus relates to above-mentioned three major types electric wire.
Medical Devices are at the medical applications of highly-specialised and design, so the employed cable of Medical Devices also must carry out particular design and just can provide optimum performance.By selecting suitable material and method for designing, can provide the cable solution that satisfies present and following high-tech medical treatment designing requirement fully.The medical grade cable can be very simple, also may be very complicated.Cable in the Medical Devices may be used to provide the either large or small electric current of power, send signal, transmits data or finish these functions simultaneously.The cable that Medical Devices use must keep consistency and reliability in the extremely wide environment of scope.All must consider mechanical property during every kind of cable design, as flexibility, flex life, anti-extrusion performance or draw and dial intensity etc.Adopt tough and tensile material can protect the conductor in the cable to preserve from.The cable of using as transmission signals many times all is the most directly to be exposed in the residing diversified external environment condition of Medical Devices, so cable design teacher need understand the environment that cable will use, cable for medical apparatus may also need particular processing and packing simultaneously, such as special processings such as sterilization and lucifuges, so cable for medical apparatus, not only real-time and the accuracy for signal all has high requirements, and for the mechanical property of cable itself very high requirement arranged also.In addition, cable for medical apparatus uses under some special environment usually, and operational environment very severe, temperature pressure change difference are subjected to the irradiation of X ray etc. greatly and directly, so cable for medical apparatus is easily aging and damaged, thereby causes equipment fault.Simultaneously, the serving of existing normal cable causes environmental pollution in case aging breakage can produce halogen etc. usually.Common cable can not satisfy several essential conditions of the cable for medical apparatus that bending property is good, the life-span is long, anti-aging and nontoxic simultaneously at present.
Therefore, demand urgently providing a kind of bending property cable making method for medical device good, that the life-span is long, anti-aging and nontoxic that can produce to overcome above defective.
Summary of the invention
The object of the present invention is to provide a kind of improved cable making method for medical device, the cable for medical apparatus bending property that is made by described manufacture method is good, the life-span is long, anti-aging and nontoxic, and can satisfy the harsh conditions that are operated in the residing diversified external environment condition of Medical Devices.
For achieving the above object, technical scheme of the present invention is: a kind of cable making method for medical device is provided, and its step is as follows: (1) with medical grade non-toxic plastic extrusion molding one layer insulating, forms lead on conductor; (2) provide some described leads to gather twisted wire and form the cable cable core; (3) outside the cable cable core, hold film, form thin layer; (4) weave with anti-elater in the thin layer periphery, form anti-elater braid, described anti-elater braid is to be formed by Fanglun 1414's braiding; And (5) use the nontoxic silica gel of medical grade extrusion molding one deck serving outside described anti-elater braid.
Preferably, described thin layer is a polytetrafluoroethylplastic plastic, and described insulating barrier is the nontoxic polyfluorinated ethylene plastic of medical grade, and described conductor is a silver-coated copper wire.
Preferably, the density of described anti-elater braid braiding be 18 orders/cun.
Preferably, in the described step (2), provide ten in lead altogether, the set twisted wire is to carry out stranded between the lay between the 60mm to 70mm.
Compared with prior art; by the made cable of cable making method for medical device of the present invention; because described thin layer coats described cable cable core; have good seal and ageing resistance; can effectively protect the insulation property of cable cable core; described anti-elater braid is woven in described thin layer periphery; has good bending; make that cable is anti-turns round anti-drawing; prolonged useful life; described serving coats described anti-elater braid; and described serving is the nontoxic silica gel of medical grade; improved the serviceability of extrusion capability and equipment, also satisfied the avirulence requirement of Medical Devices simultaneously, therefore cable of the present invention can satisfy the harsh conditions that are operated in the residing diversified external environment condition of Medical Devices.
