Description
Technical field
The present invention is a kind of pressing-vibrating type sphygomanometer, espespecially a kind of construction arm-rest belt characteristic shrinks pressure ratio value and diastolic pressure ratio to adjust, and according to the contraction pressure ratio value after adjusting and diastolic pressure ratio, find the pressing-vibrating type sphygomanometer measuring arm-rest belt characteristic of systolic arterial pressure and auterial diastole pressure.
Background technology
1733, British scientist Stephen Hales inserts the tremulous pulse of horses with the vertical brass pipe of both ends open, glass window from copper pipe is watched blood and is climbed raw height and measure mean pressure again, within 1828, Poiseuille instead of the long copper pipe of inconvenience with mercury column, the tremulous pulse mean pressure of horses can be measured through the hydrargyrum pillars of 20 centimeters, and this kind inserts the internal mode measuring blood pressure, it is referred to as intrusive mood blood pressure (Invasive Blood Pressure, it is called for short IBP), this kind of IBP measures mode and extensively applied for about halfth century, but, owing to this kind of blood pressure measuring method is the most inconvenient, therefore, medical circles thirsted for having a kind of non-intrusion type and the convenient blood pressure measuring method used always at that time.
Until late nineteenth century, Riva Rocci and Branard invention simultaneously is in terms of the non-invasion blood pressure that cuff (cuff) is made (Sphygmomanometer), the mercurial sphygmomanometer that namely we are used at present, and defined pulse tone and the relation shunk between pressure and diastolic pressure by N.S.Korotkoff in 1905.
At present in non-invasion blood pressure meter, there is a kind of pressing-vibrating type sphygomanometer, its principle is: brachial artery belongs to deep artery, its caliber about 3～4mm, but the diameter of upper arm about 7～15cm, when the blood pressure ripple (shrink pressure and diastolic pressure) in brachial artery changes out corresponding change in volume through the elasticity of tremulous pulse, and this change in volume passes through upper arm muscles, tissue etc., inwall material at the arm-rest belt through sphygomanometer reaches in arm-rest belt, according to elastic characteristicVolume change and pressure variety are proportional relations, therefore the volume change of blood vessel, and the pressure in arm-rest belt can be caused to change, and the change of this pressure is referred to as pressure and shakes ripple.
Arm-rest belt is in pressure leak process, the intrinsic pressure of arm-rest belt can diminish always, if the most endarterial blood pressure keeps constant, then transmission pressure can taper into along with pressure leak process, when transmitting pressure and being 0, represent the mean blood pressure equal to tremulous pulse of the external pressure suffered by tremulous pulse, according to the relation of arterial pressure-volume, now tremulous pulse has a volume change of maximum, corresponding also can produce a maximum pressure in arm-rest belt and shakes ripple.
Find in the pressure of bleeding process shakes ripple and shrink pressure and the feature of diastolic pressure, it is based on maximum pressure shakes wave-amplitude (Ampmax), its corresponding arm-rest belt pressure is tremulous pulse mean blood pressure (MAP), according to contraction pressure ratio value (Ratiosys) set and diastolic pressure ratio (Ratiodia), find in the pressure higher than mean blood pressure shakes ripple and shrink pressure amplitude (Ampsys), its corresponding arm-rest belt pressure is systolic arterial pressure (SysP), diastolic pressure amplitude (Ampdia) is found in the pressure lower than mean blood pressure shakes ripple, its corresponding arm-rest belt pressure is auterial diastole pressure (DiaP), wherein, this contraction pressure amplitude (Ampsys) and this diastolic pressure amplitude (Ampdia) are defined as follows:
Contraction pressure amplitude (Ampsys)=press wave-amplitude (Ampmax) * that shakes to shrink pressure ratio value (Ratiosys)
Diastolic pressure amplitude (Ampdia)=pressure is shaken wave-amplitude (Ampmax) * diastolic pressure ratio (Ratiodia)
Arm-rest belt characteristic includes arm-rest belt inwall material characteristic and arm muscles and the characteristic of tissue, although the inwall material characteristic of arm-rest belt is fixing, but the characteristic of everyone arm muscles and tissue is different, therefore, the gas of arm-rest belt loses heart speed can be different from muscle and tissue characteristics and have different disappointing speed according to everyone thickness of arm, it can thus be appreciated that in arm-rest belt bleeding process, pressure in arm-rest belt wave envelope mark characteristic of shaking is inherently different with people, cause shrinking pressure ratio value and diastolic pressure ratio is affected by arm-rest belt characteristic and produces change, now, if pressing-vibrating type sphygomanometer uses fixing contraction pressure ratio value and diastolic pressure ratio, its pressure value measured necessarily is forbidden.
