Description
Technical field
This utility model belongs to the armarium technical field, is specifically related to a kind of device on the monitor human body respiration being measured.
Background technology
On the monitor of the prior art, the measurement of breathing is to be attached on the human body appropriate location by at least two cube electrode sheets, reach the purpose of respiration measurement by the variation of electrode slice induction human body resistance when breathing, but the electrode slice quantity that this measuring method is used is more, and troublesome poeration, algorithm are also complicated.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, the respiratory wave single electrode sheet measuring device that a kind of consumptive material uses less, measuring accuracy is high to be provided.
Technical scheme: a kind of respiratory wave single electrode sheet measuring device described in the utility model, comprise electrode slice, the electric capacity Acquisition Circuit, the signal filtering treatment circuit, CPU and display, described electrode slice is connected with the electric capacity Acquisition Circuit, described electric capacity Acquisition Circuit is connected with the signal filtering treatment circuit, described signal filtering treatment circuit is connected with the input of CPU, and described electric capacity Acquisition Circuit also is connected with the input of described CPU, and the outfan of described CPU also is connected with display.
Described electrode slice quantity is one.
Described electrode slice lower end also is provided with a sheet metal, and described sheet metal directly contacts with body surface.
This utility model is affixed on sheet metal on the body surface first when using, when breathing, impel the body surface motion, the quantity of electric charge on the electrode slice is changed, thereby can be so that the capacitance in the related circuit changes, measure capacitance by the electric capacity Acquisition Circuit thus, capacitance after recording gets breath data after processing through signal filter circuit, and breath data Output Display Unit after the CPU calculation process shows breathes numerical value.
As seen from the above, need not send corresponding detection signal during this utility model work, as long as just can obtain corresponding breathing state data by the variation that gathers sheet metal appearance value, the measurement gradual change is quick and measurement data is accurate.
Beneficial effect: this utility model has solved two cube electrode sheet measuring operation trouble in the prior art, algorithm complexity, has measured coarse problem, has improved again measuring accuracy when having saved consumptive material.
