Abstract
The utility model discloses a low noise medical cable, including the sheath of outside-in arranging in proper order, weaving layer, outer shielding layer, insulating layer, internal shield layer to and the conductor. 2 shielding layers are adopted, so that the EMC performance is high; the semiconductor carbon nanotube dispersion liquid coated on the surfaces of the inner and outer shielding layers can block water, so that the influence of electric noise on signal transmission is smaller, and the requirements of high-end medical low-noise cables are met.
Description
Technical Field
The utility model relates to a low noise medical cable.
Background
In the development of the current medical industry, a stricter requirement is required for the accuracy of signal transmission of medical equipment, under the action of external factors such as bending, vibration, impact, temperature change and the like, a certain amount of electrostatic signals (or called cable structure noise) are generated by a cable, the cable with the cable structure noise smaller than 5mV is generally called as a low-noise cable, the medical cable is used as indispensable communication equipment, the accuracy of signal transmission and the anti-interference capability of the medical cable have great influence on the overall performance of the medical equipment, the current medical cable is complex in manufacturing and high in cost due to the fact that the medical cable is provided with multiple layers of shielding layers, and the cable with the single layer of shielding layer cannot be used for medical treatment.
