The present disclosure provides a method and an apparatus for assessing a physiological signal quality based on an IABP device, and relates to the technical field of medical instruments. The method includes: acquiring, in the operation process of an IABP device, physiological signal of a patient treated by the IABP device, where the physiological signal include an electrocardiographic signal and/or an arterial blood pressure signal; extracting signal parameter values of the physiological signal, where the signal parameter values include: a first kurtosis, a skewness, an effective signal ratio, a second kurtosis, and a dominant frequency; performing signal quality assessment on the physiological signal based on the signal parameter values; and implementing, based on the physiological signal, intra-aortic balloon counterpulsation in response to a signal quality assessment result represents that the signal quality of the physiological signal satisfies a preset signal quality requirement.

Method and apparatus for assessing a physiological signal quality based on an IABP device

Disclosed are a stress-resistant, creep-resistant, high-temperature resistant and high-insulation sheath material for a maglev train cable, and a manufacturing method and use thereof. A multiple chemical crosslinking structure is constructed by blending a functional polyvinylsilicone grease with ultra-high molecular weight polyethylene (UHMWPE) and a ceramicized silicone rubber as a cable material matrix and using electron beam irradiation. In addition, organic/inorganic fillers in the matrix can form physical crosslinking points in the material. A physical-chemical dual crosslinking structure is constructed in the matrix, which can limit the motion and relaxation of molecular chains and improve the interaction between the insulation layer and sheath layer and refractory layers such as fillers and mica tapes to avoid the relative displacement during the laying and operation and improve the high-temperature resistance, creep resistance and stress relaxation resistance of a UHMWPE cable sheath material.
