Inductor for respiratory volume kinescope

Abstract

The invention relates to an inductor for a respiratory volume kinescope. The inductor has a wave-type symmetrical winding structure and comprises a first part and a second part, wherein the first part and the second part are symmetrical about an axial mirror image of the inductor; the first part comprises a first tap, a plurality of coil wave valves and a first connecting part; the plurality of coil wave valves are positioned between the first tap and the first connecting part; the second part comprises a second tap, a plurality of coil wave valves and a second connecting part; the plurality of coil wave valves are positioned between the second tap and the second connecting part; the number of the coil wave valves in the first part and the number of the coil wave valves in the second part are same; the first tap and the second tap are positioned on the same side of the coil and are electrically connected with a plug; and the first connecting part and the second connecting part are mechanically and electrically connected together. Because the two taps are positioned on the same side of the coil and are connected with the plug, the inductor can be connected with a detector or a coupler only by single plugging operation. Therefore, the experimental operation is simple and convenient, and the success rate is high.

Description

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...

AI Technical Summary

Problems solved by technology

Since the area of ​​the chest (abdominal circumference) of the test object is different, and manual winding cannot guarantee consistency, the parameter consistency of this inductor is not good. When such an inductor is used in a respiratory plethysmograph, due to the parameters of each inductor are all different, so each pneumoplethysmograph needs to adjust the parameters separately, which brings a lot of trouble to the debugging work
