Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] The scheme of the hand-held four-electrode acquisition impedance information implemented by the present invention is as follows: figure 1 As shown, the impedance information and respiration information are measured by the four-electrode hand-held contact method. N+ and N- are the generating electrodes and receiving electrodes of the excitation current, and I+ and I- are the measuring electrodes, that is, the excitation currents of different frequencies are output from N+ and N-, and then converted into impedance by measuring the voltage signal between I+ and I- Signal, and then extract the ...

Abstract

The invention discloses a handheld multi-frequency-band impedance respiration signal measuring system and method. The system comprises four handheld electrodes, a sine excitation signal generating module, a sampling signal amplification circuit and a calculation, analysis and processing module. The four handheld electrodes are the excitation electrode N+, the measuring electrode I+, the measuring electrode I- and the receiving electrode N- respectively, the excitation electrode N+ is connected to the output end of the sine excitation signal generating module, and the receiving electrode N- is connected to the input end of the sine excitation signal generating module. The measuring electrode I+ and the measuring electrode I- are connected to the sampling signal amplification circuit. According to the measuring system and method, after the strong influence of baseline drift is effectively removed, through establishment and comparison of amplitude monitoring motion information and a standard respiration template, baseline drift and motion interference can be more accurately eliminated, and therefore respiration signals and the respiration rate are accurately measured.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to an impedance type respiratory signal measurement system. Background technique [0002] With the popularization and application of BIA (Bioelectrical Impedance) technology, there are more and more products to detect human health status by obtaining body composition parameters through BIA, and the way of collecting impedance information has also evolved from 2 electric levels to With 4 electrodes and 8 electrodes, the excitation current has also increased from single frequency to multi-frequency band analysis, and the detection parameters have become more and more abundant. Not only can the impedance value be detected, but also various body components can be calculated and obtained to provide more accurate and useful information for healthy life. Reference, and can also obtain respiratory signals through upper limb impedance information, providing an additional layer of s...
