Specific implementation process of the present utility model is as follows:
When this sensing device carries out blood oxygen saturation mensuration, make use of Lambert-Bear law.According to Lambert-Bear law, when being incident in dactylus with a specific wavelength, transmitted light intensity is characterized primarily by two parts, a part is constant basis, main reflection muscle, skeleton, fat, moisture, venous blood etc. are for the absorption of light, another part is pulsating quantity, follows heartbeat and changes, and in main reflection arterial blood, deoxyhemoglobin and HbO2 Oxyhemoglobin are to the absorption of light.
Use and during this sensing device, finger is stretched in device, now, at rubber parcel cover with under the combined effect of resiliency supported net, the first infrared-emitting diode of the first photoelectric sensor and the second infrared-emitting diode are right against the middle-end dactylus abdominal part of finger, and with finger skin close contact; First infrared photosensitive reception audion is right against the middle-end dactylus back of finger, and with finger skin close contact.Finger position is fixed rear outside timesharing drive circuit and is allowed the first infrared-emitting diode and the second infrared-emitting diode by certain time interval and distinguish with lower dutycycle luminous, and peripheral circuit gathers the signal passed back in the first infrared photosensitive reception audion.According to Lambert-Bear law, when the first infrared-emitting diode launches 660nm infrared light, the signal D of reflection transmitted light intensity constant basis in the first infrared photosensitive reception audion, can be detected
660with the signal A of reflection transmitted light intensity pulsating quantity
660; When the first infrared-emitting diode launches 940nm infrared light, the signal D of reflection transmitted light intensity constant basis in the first infrared photosensitive reception audion, can be detected
940with the signal A of reflection transmitted light intensity pulsating quantity
940.HbO2 Oxyhemoglobin and the deoxyhemoglobin ratio for the trap change of different wavelengths of light can be obtained thus
according to formula S pO after obtaining Q
2=A+BQ calculates blood oxygen saturation, and wherein A and B represents that first, second demarcates constant respectively.Whole blood oxygen saturation measures about 30 seconds consuming time of process.
When this sensing device carries out blood pressure and heart rate measurement, arteriotony is Development pattern fluctuation with the contraction of ventricle and diastole, and when ventricular systole, the maximum of arteriotony is called systolic pressure; During ventricular diastole, the minima of arteriotony is called diastolic pressure.When using this sensing device, finger is stretched in device, now, at rubber parcel cover with under the combined effect of resiliency supported net, 3rd infrared-emitting diode of the second photoelectric sensor and the second infrared photosensitive reception diode are right against the far-end dactylus abdominal part of finger, and with finger skin close contact.After finger position is fixing, the inflation of inflation finger ring given by the inflator pump of external pressure adjusting device, until the pressure that gas pressure sensor records in inflation finger ring reaches 200mmHg, at this moment inflates finger ring and presses finger blood vessel, finger interior blood is not flowed.
Pressure-regulating device mainly comprises electric inflating pump, ventilating control electromagnetic valve, venting Controlling solenoid valve.Wherein, the gas outlet of electric inflating pump is connected with ventilating control electromagnetic valve one end by trachea, and the ventilating control electromagnetic valve other end is connected with inflation finger ring inflation inlet; Venting Controlling solenoid valve one end is connected with inflation finger ring gas vent by trachea, and the other end is connected with atmospheric environment.When the inflation of inflation finger ring given by needs, electric inflating pump is opened, and ventilating control electromagnetic valve is opened, and venting Controlling solenoid valve is closed.After force value reaches setting value in inflation finger ring, close electric inflating pump and ventilating control electromagnetic valve simultaneously.When the venting of inflation finger ring given by needs, open venting Controlling solenoid valve.When pressure drops to setting value in inflation finger ring, close venting Controlling solenoid valve.
After inflation terminates, control pressure in inflation finger ring by external pressure adjusting device and decline with the speed of 3 ~ 5mmHg, gas pressure sensor measures the pressure in inflation finger ring all the time simultaneously.Meanwhile, the second photoelectric sensor is started working, and namely the 3rd infrared-emitting diode launches infrared light, and the second infrared photosensitive reception diode detects whether receive reflects infrared light in real time.
When in inflation finger ring, pressure is greater than systolic pressure, because finger blood vessel constriction is compeled thus internal blood stopping flowing, now the second infrared photosensitive reception diode can't detect reflects infrared light, namely can't detect pulse signal; In inflation finger ring, pressure continues to decline, when reaching systolic pressure, finger inner blood starts Generation-Atomic Fluorescence Spectrometry, now the second infrared photosensitive reception diode detects reflects infrared light, namely pulse signal is detected, this signal is gathered by peripheral circuit, and the inflation finger ring pressure that now gas pressure sensor is measured is systolic pressure; When in inflation finger ring, pressure continues to decline, reach diastolic pressure, now do not suffer oppression owing to pointing interior blood vessel, blood flow is even, second infrared photosensitive reception diode can't detect reflects infrared light, namely pulse signal disappears, and when peripheral circuit detects this state, the inflation finger ring pressure that gas pressure sensor is measured is diastolic pressure.
Be certain linear relationship owing to pointing systolic pressure and the diastolic pressure of tremulous pulse and aortal systolic pressure with diastolic pressure, the systolic arterial pressure that correction is pointed and diastolic pressure, obtain blood markers accurately.When calculating heart rate, only need to carry out counting to the pulse signal recorded and calculate in proportion obtaining heart rate after pulse signal being detected within the set time.
Above-mentioned detailed description of the invention is used for explaining and this utility model is described; instead of this utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make this utility model and change, all fall into protection domain of the present utility model.
