Referring to fig. 1, fig. 1 is a schematic diagram of a physiological data acquisition device 30 according to an embodiment of the present application. The physiological data acquisition device 30 is used for acquiring physiological data of a monitored object. The physiological data acquisition device 30 includes an acquisition box 31, a lead wire 32 and a measurement end 33. The lead wire 32 is connected between the collecting box 31 and the measuring terminal 33. Each of the lead lines 32 includes at least one or more first lead lines 322 having an impedance greater than a predetermined threshold. The measuring end 33 is adapted to be fitted to the body of a patient to obtain a measuring signal. The first lead wire 322 is used for reducing the voltage of the measurement signal, and the collection box 31 is used for processing the reduced voltage measurement signal to obtain physiological measurement data.

Therefore, the self impedance of the first lead wire 322 is adopted as a defibrillation protection component, the high voltage is defibrillated by a human body through the process that the first lead wire 322 enters the acquisition box 31, because the first lead wire 322 has proper impedance, the high voltage reduction processing of the defibrillation can be realized, no additional discrete high-power voltage resistance device is needed to realize high-voltage protection, the requirement on the interface is low, the acquisition box 31 is miniaturized, and the defibrillation protection performance can meet the standard requirement while the better comfort is provided.

The present application selects the core wire material of the first lead wire 322The material can meet the requirements of defibrillation protection of the circuit. Wherein the material is selected mainly considering the resistivity and power parameters of the material, for example, the length of the lead wire is 0.3m, and the cross-sectional area of the lead wire is 0.16mm²For example, to achieve a 40k Ω resistance, the resistivity of the material required is calculated to be not less than 21.3m Ω m, and the power required to be tolerated is not less than 400W. Therefore, since the resistivity of the common metal wire is too small to meet the impedance requirement, the core wire of the first lead wire 322 needs to be made of other materials, for example, a polymer conductive composite material including a carbon fiber composite material, conductive PVC, etc.

Specifically, in one embodiment, at least a portion of the core of the one or more first lead wires 322 is made of a polymer conductive composite.

Further, in one embodiment, the polymer conductive composite material comprises a mixture of a conductive polymer matrix material and a conductive filler, wherein the conductive polymer matrix material is used for firmly bonding the conductive particles together, so that the conductive filler has stable conductivity and also endows the material with processability; the conductive filler provides a carrier function, and its morphology, properties and amount directly determine the conductivity of the material.

In one embodiment, the conductive filler is conductive particles, that is, the polymer conductive composite material is implemented by doping conductive particles, and when the filler concentration of the conductive particles is low, the conductive particles of the filler are dispersed in the polymer, and contact with each other very little, and the conductivity is very low. With the increase of the filler concentration of the conductive particles, the probability of the filler particles contacting with each other is increased, the conductivity is gradually increased, when the filler concentration reaches a certain critical value, the filler particles in the system contact with each other to form a wireless network chain, and the network chain penetrates through the polymer like a metal network to form a conductive channel, so the conductivity is increased sharply, and the polymer becomes a conductor.

Further, in one embodiment, the conductive polymer matrix material includes any one or more of the following: polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS, epoxy resin, acrylate resin, phenol resin, unsaturated polyester, polyurethane, polyimide, silicone resin, butyl rubber, styrene-butadiene rubber, nitrile rubber, and natural rubber.

Specifically, in the scheme that the core wire of each lead wire 32 is replaced by a polymer conductive composite cable, the core wire of the whole lead wire 32 may be replaced by the polymer conductive composite cable, that is, each lead wire 32 only includes the first lead wire 322; alternatively, as shown in fig. 1, the core wire of the entire lead wire 32 may be replaced with a polymer conductive composite cable, for example, the core wire of the lead wire 32 has a mixed structure of the conductive wire 320 and the first lead wire 322 including the polymer conductive composite cable. Further, in one embodiment, the conductive wire 320 and the polymer conductive composite cable may be connected by crimping. That is, each conductive line 32 is formed by splicing one or more segments of the first conductive line 322 and one or more segments of the conductive line 320.

Therefore, one or more sections of the self impedance of the first lead wire 322 are used as a defibrillation protection component through the splicing, when the defibrillation high voltage enters the acquisition box 31 through one or more sections of the first lead wire 322 by a human body, because one or more sections of the first lead wire 322 have proper impedance, the defibrillation high voltage can be completed to reduce the voltage, and the high voltage protection is realized without an additional discrete high-power resistor device, so that the monitoring system 100 has a simple structure, has low requirement on interface voltage resistance, and is very convenient for the wearable type and other miniaturized ECG measurement devices or the defibrillation protection design of the measurement devices directly electrically coupled with the monitored object.

The lead wire 32 may be a single core wire or a multi-core wire. When the lead wire 32 is a single core wire, the core wire of the lead wire 32 may be entirely replaced with the polymer conductive composite cable, or partially replaced with the polymer conductive composite cable.
