Description
Technical field:
This utility model belongs to medical Instrument field, is specifically related to a kind of new Digital sphygomanometer.
Background technology:
Along with the growing interest of people to physical condition, the blood pressure monitoring has entered into daily life with measurement.Existing a variety of digital blood pressure meters on the market are owing to the good favor that is subjected to ordinary consumer of its intuitive.
Wherein a kind of commodity arteries and veins ephemeris (MediWatch) can non-intervention type measurement intra-arterial blood pressure waveform, and then obtain systolic pressure and diastolic pressure, and its measurement result satisfies the requirement (2001) of AAMI and BHS. its operation principle: 1) use tonometry (tonometry) (passing through pressure transducer) to obtain radial artery (radial artery) impulse waveform; 2), further obtain actual systolic pressure and diastolic pressure by calibration to this impulse waveform.Structure and operation: 1) piston is pressed into wrist, until the radial artery radius half, guarantees that pressure transducer can both be experienced pulse in any case; 2) variation of vibrating diaphragm place will cause the variation of the output voltage of pressure transducer; 3) 3 fixed systems: a) under the gauge outfit, b) radius band, and c) the ulna band.MediWatch has utilized the linear relationship of radial artery pressure impulse waveform and actual blood pressure ripple, thereby by blood pressure measurement is carried out in the calibration of radial artery pressure impulse waveform.Its main contribution is that its Machine Design (piston, 3 fixed system designs) can obtain stable radial artery pressure impulse waveform.Deficiency is: piston need be pressed in the wrist, and long-time measurement may cause discomfort; Need calibration.
The Vasotrac system need not calibration, need not cuff and just can measure systolic pressure and diastolic pressure. and the FDA that it obtains the U.S. in nineteen ninety-five authenticates.Primary structure: 1) hydraulic regulating device: be used to change the external pressure that is added in the wrist place; 2) pressure transducer: be used to obtain pressure waveform.Concrete operations and measuring principle: 1) find out optimum pressure pick off putting position :-pick off is probably placed the radial artery place, change pressure, wave recording;-find the external pressure PO of amplitude peak waveform place correspondence;-keep external pressure PO constant, change sensing station, wave recording;-find corresponding sensor position, amplitude peak waveform place, be the optimum position.2) change external pressure, wave recording.Select near the several waveforms the amplitude peak waveform, find out characteristic parameter (such as amplitude, etc.) from waveform.3) set up blood pressure estimate equation: F according to characteristic parameter and represent (non-) linear function, P representation feature parameter, C is a coefficient.Usually, C can carry out the acquisition of (non-) linear fit to clinical data.4) obtain systolic pressure and diastolic pressure.Advantage: Vasotrac/Vasotrax can need not cuff, the measurement blood pressure that need not to calibrate.Under different clinical conditions, its measurement result is in close proximity to the insertion type measurement result.Deficiency is: user needs certain experience just can find best pick off putting position; Vasotrac/Vasotrax is very sensitive to motion artifact; The blood pressure measurement of beat-to-beat can not be provided.
