Description
Technical field
The present invention relates to medical auxiliary equipment fields, more particularly to a kind of multifunctional blood pressure cuff and air charging system.
Background technique
Blood pressure is clinically particularly important vital sign, and it is considered as non -invasivetesting that mercury sphygmomanometer, which measures blood pressure,
Goldstandard.It has been known that there is the more multifactor accuracys that can influence blood pressure measurement:
Wherein inappropriate cuff selection is the most common reason for causing blood pressure measurement error.American Heart Association
(American Heart Association, AHA) new blood pressure measurement guide is pointed out, in order to accurately measure blood pressure, is reduced and is surveyed
Measure error, it is desirable that cuff air bag at least covers the 80% of upper arm upper-arm circumference, and width is at least up to the 40% of upper-arm circumference.Therefore will with it is upper
The cuff air bag institute measuring blood pressure that arm matches could represent actual blood pressure, avoid because cuff select it is improper caused by false hypertension
Or false low blood pressure.The previous sphygmomanometer of mesh is conventional only with an adult model cuff (balloon size is 12cm × 22cm), gas
Capsule size is fixed, and measured crowd (22-26cm of upper-arm circumference, small idiotype are adult) target compares limitation, and actual environment is more personal
Height increases, physique is larger, upper-arm circumference and calf circumference belong to big type adult or adult OS OVER SIZE, and existing blood pressure cuff air bag is not
Matching upper-arm circumference, brachium and cause blood pressure measurement error.
But the previous sphygmomanometer of mesh only matches a cuff air bag, how showing according to only one existing cuff air bag
Reality condition accurately to measure blood pressure to be that we will solve the problems, such as at present.
The inflating balloon size of existing blood pressure cuff standard configuration is relatively small, and aeration speed is slow, is easy aging, and gas outlet uses
Screw thread mouth nut elasticity adjusts gas outlet size, and the control of screw thread mouth elasticity is more difficult, cannot accurately control the speed of discharge quantity
