technical field
[0001] The present invention relates to an inductor, in particular to an inductor for a breath plethysmograph. Background technique
[0002] Respiratory plethysmography is a method that can non-invasively measure ventilation and perform quantitative analysis. The main structure of the measurement device is to wrap two insulated sensing coils around the chest and abdomen of the subject through elastic bandages or other methods. Breathing movement can lead to contraction of the chest and abdomen, resulting in changes in the cross-sectional area of the corresponding parts of the chest and abdomen. Driven by the elastic band, the cross-sectional area surrounded by the insulating sensing coil also changes, resulting in The coil senses the change of the volume of the coil, and the respiratory plethysmograph detects the change of the cross-sectional area of the corresponding parts of the chest and abdomen by detecting the change of the self-inductance of the sen...
