Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
A kind of multi-parameter life sign measuring device comprise temperature sensor, Photoelectric sphygmograph sensor, respiration pickup, cuff, for cuff inflation air pump, for control the gas discharging in cuff vent valve, for detecting the pressure transducer of the gas pressure in cuff, pressure sensor signal treatment circuit, Photoelectric sphygmograph sensor signal processing circuit, respiration pickup signal processing circuit, A/D change-over circuit, communication module and controller.Adopt after technique scheme, namely can realize the measurement to the blood pressure embodying human body vital sign, temperature, heart rate and breathing with a kind of device, decrease medical personnel's workload, improve work efficiency, structure chart is as Fig. 1.
This utility model adopts a controller by blood pressure, body temperature, heart rate, breathes these 4 parameter acquisitions and to show on host computer in real time.Wherein pressure transducer adopts MPS2107 sensor, blood pressure measurement adopts oscillographic method, the judgement of systolic pressure and diastolic pressure adopts amplitude coefficient method, on the basis of great many of experiments, this programme has carried out certain improvement to amplitude characteristic ratios method, do not adopt fixed proportion coefficient, but the proportionality coefficient different according to mean pressure different set.Body temperature trans adopts DS18B20, and heart rate sensor adopts the integrated pulse transducer of HK-2000 series, and respiration pickup adopts HKH-11B respiratory wave sensor.Communication module adopt serial communication, controller to the flow process of 4 large parameter measurements as Fig. 2.
Wherein, blood pressure measurement adopts oscillographic method, and the judgement of systolic pressure and diastolic pressure adopts amplitude coefficient method, on the basis of great many of experiments, this programme has carried out certain improvement to amplitude characteristic ratios method, does not adopt fixed proportion coefficient, but the proportionality coefficient different according to mean pressure different set.
Wherein, body temperature trans adopts DS18B20, and its collection temperature survey and A/D are transformed in one, directly export digital quantity, therefore are connected with controller and do not need additional A/D circuit, and controller directly can process the digital quantity of its output.
Wherein, the measurement of heart rate adopts photoplethysmograph, and when the light beam irradiation of certain wavelength is to finger tip skin surface, light beam will be sent to photelectric receiver by reflection mode.In the process owing to being subject to the attenuation by absorption effect of finger tip integumentary musculature blood, the light intensity that detector detects will weaken.Wherein integumentary musculature, tissue etc. are keep invariable to being absorbed in whole blood circulation of light, and the change in pulsation under key role of the volumetric blood in skin, peripheral blood capacity is maximum when the heart contracts, and absorbing amount is also maximum, and the light intensity detected is minimum; And
When diastole, just in time on the contrary, the light intensity that the most ambassador's optical receiver of the light intensity detected the receives change in pulsating nature thereupon.Convert this intensity variation signal to the signal of telecommunication, just can obtain the change of volume pulse blood.
Wherein, the measurement of breathing adopts pressure transducer, and pressure transducer is also referred to as strain gauge transducer.During respiratory movement, along with exhaling and the periodic transformation of air-breathing, corrugated hose and thorax abdomen all can produce periodic deformation.Pressure transducer is exactly from this phenomenon, manages this cyclic deformation experiencing corrugated hose and abdominal part when breathing, measures respiratory frequency with this.
The output signal of piezoelectric transducer is very faint, generally needs just can detect after signal of telecommunication amplification.According to the operation principle of piezoelectric transducer, what sensor exported is voltage signal or charge signal, and therefore preamplifier also has two kinds of forms; One is voltage amplifier, and its output voltage is directly proportional to input voltage, the so-called impedance transformer of this amplifier; Another kind is charge amplifier, and its output voltage is directly proportional to input charge amount.According to hydrodynamics and thermodynamic principles; people is when breathing; because of the flowing of gas; the gas of flowing can to producing instantaneous pressure around; if placement force sensor on corrugated hose; breath signal can be converted to voltage signal by this pressure transducer, then by amplification, detection and A/D conversion, or recorded again and date processing by power amplification; Also pressure transducer can be placed on chest or abdominal part, alternately change according to the expansion in thoracic cavity and the rhythmicity that reduces, cause chest, the fluctuations of back and abdominal part produces voltage signal, then carry out processing and amplifying, can breath signal be obtained.
