Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1, the low-noise blood oxygen wire provided by this embodiment includes two sets of signal wire bodies distributed in parallel and an outer protective layer 1 covering the two sets of signal wire bodies to form a non-circular structure with a radial cross-section, where each set of signal wire body includes a cabling core formed by twisting two conductor wire cores 3 each having an insulating layer 2 coated on the outer periphery thereof and a shielding layer 4 covering the outer periphery of the cabling core. In view of the fact that the conventional blood oxygen wire is structured by adopting a round wire structure, in order to ensure the low noise performance of the wire, a large amount of shielding materials are often needed, which easily causes the series of problems of over-thickness of the wire, over-heavy weight and the like, in the embodiment, two groups of signal wire bodies are uniformly coated by an outer protective layer 1 to form a structure body with a non-circular overall radial cut-off surface, so that not only can each group of signal wire bodies be integrated, but also the signal interference and shielding isolation between the signal wire bodies are realized through respective insulating layers 2 and shielding layers 4, the anti-interference capability in the signal sending and receiving processes is effectively enhanced, and structural conditions are created for reducing the using amount of the shielding materials while ensuring the low noise performance of the.
