Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As it is shown in figure 1, a kind of device for detecting obstructive respiration obstacle, including acceleration transducer, analogue signal Pretreatment circuit, A/D converter, Skin resistance sensor and single-chip microcomputer, described analogue signal pretreatment circuit includes simulation letter Number amplifying circuit and analogue signal filter circuit;Described acceleration transducer is for gathering the human body breast/abdominal part under sleep state Respiratory movement analogue signal, described analogue signal pretreatment circuit for described respiratory movement analogue signal is amplified and Filtering Processing, described Skin resistance sensor is used for gathering skin resistance signal, and described A/D converter will be for believing through simulation The respiratory movement analogue signal of number pretreatment processing of circuit is converted into digital signal, and described single-chip microcomputer is for believing according to skin resistance Number and digital signal carry out obstructive respiration obstacle judgement, described single-chip microcomputer connects A/D converter and Skin resistance sensor.
Wherein, acceleration transducer is single shaft or multi-axial sensor, specially 3-axis acceleration sensor.
Skin resistance sensor is two metal electrodes contacted with human body, and its effect is to measure Skin Resistance.
Also include the button inputted for external information and external control instruction and for exporting the display screen of monitoring result, Described button and display screen all electrically connect with single-chip microcomputer.
Also including the carrier for fixing acceleration transducer, time specifically used, carrier is for for by acceleration transducer Be attached to human body breast/abdominal part binding agent or for described acceleration transducer is fixed on human chest/abdominal part bandage or Adhesive tape, described bandage is elastic bands, wears conveniently.
This method of testing being used for detecting the device to test sleep quality breath state of obstructive respiration obstacle:
(1) respiratory movement analogue signal and the skin resistance signal of abdomen/chest of the breast/abdominal part of human body are gathered;
(2) the respiratory movement analogue signal of breast/abdominal part is converted into digital signal by A/D converter;
(3) according to the relation between the digital signal in step (2) and the skin resistance signal of abdomen/chest, human body is slept Dormancy breath state judges.
The application describes the use principle of this detection device as a example by single-axis sensors:
As in figure 2 it is shown, the body surface motor message containing respiration information of the human body under collection sleep state: acceleration is passed Sensor, directly against being attached to breast/abdominal part or being fixed on breast/abdominal part with bandage, utilizes acceleration transducer to sense chest/abdomen when breathing The change of acceleration in portion's motor process, obtains respiratory movement analogue signal, and this respiratory movement analogue signal is clear through display screen Demonstrate respiratory movement waveform, for the monitoring of sleep-respiratory.
The pair of electrodes of Skin resistance sensor is fixed on the abdomen/chest of human body, utilizes Skin resistance sensor to sense The change at respiratory middle impedance of abdomen/chest during breathing, obtains skin resistance signal, and this skin resistance signal is through display screen Clearly show that respiratory waveform, for the reference value of acceleration transducer sensing gained respiratory movement waveform.
In this acquisition mode, utilize that acceleration transducer senses is the acceleration of motion of the tested measuring point of breast/abdominal part, During human body air-breathing, human abdomen is moved upward by minimum point, first half section be acceleration upwards and gradually decrease to 0 acceleration fortune Dynamic, the second half section is the retarded motion that acceleration is downward, and when the speed moved upward is kept to 0, the displacement moved upward is maximum, inhales Gas process completes;During human exhaled breath, human abdomen is moved downward by peak, and first half section is that acceleration downwards and is gradually reduced to The accelerated motion of zero, the second half section is acceleration running slowly upwards, when downward speed is kept to 0, the displacement moved downward Maximum, exhalation process terminates.
Having periodically owing to breathing under normal circumstances, therefore corresponding accelerating curve is also rendered as cyclically-varying Curve, it can be considered that become reverse from maximum forward or backwards on curve or forward is maximum, by reverse or forward is maximum Become being a breathing cycle forward or backwards to the maximum.
Described analogue signal pretreatment circuit includes amplifying circuit of analog signal and analogue signal filter circuit, due to simulation Signal pre-processing circuit volume is little, low in energy consumption, use acceleration transducer and analogue signal pretreatment circuit, A/D converter and Single-chip microcomputer is together located in described carrier, to save installing space, in order to reduce the volume that equipment is overall.
Described single-chip microcomputer includes at the analysis for analyzing, process described respiratory movement analogue signal and skin resistance signal Reason module.
As shown in Figure 4, during concrete use, the respiratory movement analogue signal warp of described acceleration transducer output Cross that respiratory movement analogue signal is amplified by analogue signal pretreatment circuit, input a/d converter carries out mould after Filtering Processing Number conversion, then uploads to the digital signal through analog digital conversion the analysis and processing module of single-chip microcomputer, passes through analysis and processing module In ICA algorithm carry out the analysis of blind source, can extract easily acceleration transducer sensing breathe time breast/abdominal exercise process In the respiratory movement analogue signal that obtains due to acceleration change and the skin resistance signal of Skin resistance sensor sensing, And clearly show that respiratory movement waveform and respiratory waveform by display screen, utilize acceleration transducer to accurately detect To small acceleration change, good output waveform, it is possible to accurately measure the process of breathing.
