Abstract
The invention discloses a respiration sensor which comprises a housing, a leading wire, conductive electrodes and a high-polymer piezoelectric material filled between the electrodes. When the sensor is used for sensing the respiration of a human body, and thoracic and abdominal telescopic motion can enable the pressure on the high-polymer piezoelectric material to change. The high-polymer piezoelectric material can transform the changes in the pressure to electric charge signals, and respiration signals can be further obtained through a follow-up processing circuit. The respiration sensor has excellent properties of fast response speed, high sensitivity and good linearity, and can be made into a thin film or a cable or other shapes according to needs and be applied to infant respiration monitoring, sleep respiration monitoring, respiration monitoring under medical research and special operations and the like, so that the respiration sensor is an universal sensor for getting the respiration signals.
Description
[technical field]
The present invention relates to sensor technical field, be specifically related to a kind of respiration pickup that is used for monitoring of respiration.
[background technology]
The pick off that is used for monitoring of respiration at present mainly contains three kinds.First kind is the heat-sensitive type pick off, and the variations in temperature that causes through breathing obtains breath signal; Second kind is differential pick off, and the air pressure change that causes through breathing obtains breath signal; The third is to adopt to tie up to the peripheral elastoresistance band of breast abdominal part, and the resistance variations that causes through breathing obtains breath signal.The signal of first kind of pick off is easy to influenced by ambient temperature, and second kind of pick off requires user to wear mask, and the signal of the third pick off has very big null offset.
[summary of the invention]
Main purpose of the present invention provides a kind of simple and effective monitoring of respiration means.
Be to realize above-mentioned purpose, the present invention provides a kind of respiration pickup, is made up of shell, lead-in wire, conductive electrode and the high polymer piezoelectric material that is filled between the electrode.High polymer piezoelectric material comprises Kynoar (PVDF), polyvinyl fluoride (PVF), polrvinyl chloride (PVC) etc., is a kind of flexible piezoelectric material.This piezoelectric can produce charge signal when being under pressure.During human body respiration, the breast abdomen can carry out periodic stretching motion, this motion of respiration pickup sensing, and the pressure that makes high polymer piezoelectric material receive changes.High polymer piezoelectric material is a charge signal with the change transitions of this pressure, is drawn by lead-in wire, and the treatment circuit through follow-up can obtain breath signal.
This pick off can be processed shapes such as thin film or cable as required, can be applied to monitoring of respiration under infant breathes monitoring, sleep-respiratory monitoring, medical research and the special operation etc., is a kind of general purpose transducer that is used to obtain breath signal.
Capable beneficial effect of the present invention really is:
This respiration pickup adopts high polymer piezoelectric material as sensing material, has the good characteristic that response speed is fast, highly sensitive and the linearity is good, has guaranteed the accuracy and the accuracy of monitoring of respiration.Simultaneously, this respiration pickup is prone to process sheet or the pipe that arbitrary shape and area do not wait, and produces simple.
[specific embodiment and description of drawings]
The application's characteristic and advantage will be through embodiment, in conjunction with the accompanying drawings.
Fig. 1 is the sketch map of film like respiration pickup, is made up of shell, lead-in wire, upper/lower electrode and high polymer piezoelectric material, and high polymer piezoelectric material is filled between top electrode and the bottom electrode.The respiration pickup of this film shape is extremely thin; And very soft, it is attached to the front, the pressure that the respiratory movement meeting of human body receives thin film changes; High polymer piezoelectric material is a charge signal with this pressure change transitions; Drawn by lead-in wire, the processing of circuit through follow-up just can obtain breath signal.
Fig. 2 is the sketch map of cable shape respiration pickup, is made up of shell, lead-in wire, screen layer, internal and external electrode and high polymer piezoelectric material, and between electrode and the external electrode, screen layer was used for shielding extraneous interfering signal in high polymer piezoelectric material was filled in.As shown in Figure 3; The respiration pickup of this cable shape is placed in the thin pad equably, fills up last time when the people lies in to approach, the pressure that the respiratory movement meeting of human body receives cable changes; High polymer piezoelectric material is a charge signal with this pressure change transitions; Drawn by lead-in wire, the processing of circuit through follow-up just can obtain breath signal.
Above content is to combine a kind of embodiment to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
