Medical cable assembly, medical cable and manufacturing method thereof

Abstract

The invention provides a medical cable assembly, a medical cable and a manufacturing method thereof, the medical cable comprises a cable core and a plurality of layers of jackets wrapping the periphery of the cable core, and the cable core is composed of a plurality of steel wire fibers. According to the medical cable assembly, the medical cable and the manufacturing method of the medical cable, due to the fact that the steel wire fibers are adopted as the cable cores, the bending life of the medical cable assembly can reach ten times of that of a cable in the existing market, the bending life of the medical cable assembly can reach 120 thousand times and is far larger than that of a good foil wire cable in the existing market, and the tensile strength of the medical cable assembly can also reach 200-300 N, which is far greater than 50-150 N of a foil wire cable; meanwhile, the steel wire fibers have good heat conduction and corrosion resistance, the conductive impedance is very small, the ohm / m level can be reached, the conductive impedance is about 1-50 ohm / m, the technical requirements of the electrocardio lead wire are met, by improving the performance, the stability and accuracy of electrocardiosignal drawing are effectively improved, and the expected service life is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical cable assembly, a medical cable and a manufacturing method thereof. Background technique [0002] Among the external application accessories of the ECG machine, the ECG lead wire is a necessary medical accessory used with the ECG machine. The ECG lead wire is also a medical device with independent sales. It can be seen that the use value of the ECG lead wire and Quality reliability is an important index to measure the ECG lead wire. [0003] The main components of the lead wire are: plug end, main cable, branch cable, junction box end (YOKE end), and patient application electrode end. Terminal and patient application electrode terminal reliability wire harness processing technology is a key indicator for evaluating ECG lead wires. [0004] The specifications and structures of the existing ECG lead wire cables are all non-standard cable designs, and the materia...
