Abstract
The utility model discloses a medical equipment cable which comprises a cable core, a shield and a protective layer; the cable core comprises two signal lines and three power cords as well as two or three filled cores, wherein the two signal lines comprise two coaxial cables; the inner jack of each signal line is made of semi-conductive material; the shield adopts an aluminum foil layer and a woven layer to shield and has strong anti-electromagnetic interference capability; the woven layer is made of a tinned copper wire and has good corrosion resistance; the outer protective layer is made of wear and bending resistant jack material, thereby improving the weather resistance of the medical cable and prolonging the service life thereof; and the medical equipment cable solves the problems of serious weak signal transmission attenuation, poor anti-electromagnetic interference capability and the like of the prior art.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of cable that is applied to field of medical.
Background technology
Along with science and technology in military affairs, industry, various fields such as medical treatment all are faced with the measurement problem of small signal, for example: be used to measure " sonar " system of sound under water in the naval vessels, measure radioactive probe in the atomic energy industry, measure the thermocouple thermometer of reactor internal temperature, measure the piezoelectric element vibrometers such as vibratory impulse of boats and ships, aircraft, rocket, impact metre, accelerometer, therapeutic medical electrocardiograph, brain electricity meter or the like.The development of medical technology, the improvement of Medical Devices medically faces a lot of difficult medical problem and is implemented step by step now, and Medical Devices are faced with the measurement problem of small signal, are connected by cable between detecting head and the Medical Instruments.Measuring all is to search small signal with a probe, be transferred to the high impedance high-gain amplifier by a coaxial cable, realize that through amplifier signal amplifies, if the pulse signal that cable itself produces will produce noise greater than 5 millivolts, this noise signal is more strong in mechanical movement, therefore cable design and cable performance require to influence testing level to a great extent, thereby influence the medical science level.
The utility model content
The purpose of this utility model is to provide a kind of Medical Devices cable, solves problems such as the serious and anti-electromagnetic interference capability difference of the small-signal transmission attenuation that exists in the prior art.
In order to achieve the above object, the utility model adopts following technical scheme: described Medical Devices cable is made up of cable core, shielding and sheath, cable core comprises two holding wires and three power lines, and two or three filled cores, wherein two holding wires are made of two coaxial cables, this holding wire can transmit low frequency signal, and the inner sheath of holding wire adopts semiconductive material to constitute.
Further, holding wire adopts coaxial configuration, and transmitted test signal, power line are finished the input to device current, have realized having concurrently simultaneously the comprehensive transmission performance of transmission signals and electric current.
Further, aluminium foil and braiding double layer screen are adopted in described shielding, and anti-electromagnetic interference capability is strong, and braiding adopts is tinned copper wire, so good corrosion resistance.
Further, described outer jacket adopts wear-resisting, and the sheath material of anti-bending has improved the weatherability of medical cable, has prolonged its useful life.
Compare with prior art, the utlity model has following advantage:
1, weatherability is strong: sheath adopts with wear-resisting, the sheath material of anti-the bending, and weatherability is significantly improved;
2, anti-electromagnetic interference capability is strong: screen adopts aluminium foil and braiding double layer screen, and anti-electromagnetic interference capability is significantly improved;
3, decay resistance is strong: the braid in the screen adopts tinned copper wire, and decay resistance is improved.

Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
The Medical Devices cable that the utility model relates to is made up of cable core, shielding and sheath, cable core comprises two holding wires and three power lines, and two or three filled cores, wherein two holding wires are to be made of two coaxial cables, this holding wire can transmit low frequency signal, the inner sheath of holding wire adopts semiconductive material to constitute, and holding wire adopts coaxial configuration; Aluminium foil and braiding double layer screen are adopted in shielding, and anti-electromagnetic interference capability is strong, and braiding adopts is tinned copper wire, good corrosion resistance; It is wear-resisting that outer jacket adopts, and the sheath material of anti-bending has improved the weatherability of medical cable, has prolonged its useful life.
More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, any those skilled in the art can think variation, all should drop in the protection range of this patent.
