Abstract
The non-invasive sphygmomanometer analyzer includes one dynamic blood pressure simulator to simulate the blood pressure change of human body and to apply one dynamic blood pressure to the air bog of the sphygmomanometer adaptor and one standard pressure measuring device for the dynamic analysis of sphygmomanometer.
Description
Technical field
This patent belongs to sphygomanometer and analyzes the measurement technology category, and the analysis and the appraisal procedure of the dynamic characteristic of sphygomanometer is provided, and is applicable to occasions such as sphygomanometer metering, calibrating and quality inspection.
Technical background
Hypertension diagnosis conventional equipment is a sphygomanometer, and its performance test and quality control are the important assurances of quality of medical care.But, static method of testing is only adopted in sphygomanometer Performance Detection and analysis at present, and only be applicable to minority simulation sphygomanometer, as mercurial sphygmomanometer, and can't test for the digital blood pressure meter of those lash methods, oscillographic method, and widely used clinical non-invasive blood pressure monitor commonly used and family's electric sphygmomanometer commonly used all are digital sphygmomanometers, and it is significant therefore to measure this class sphygomanometer.At present, the method and apparatus that does not also have a kind of effective sphygomanometer dynamic analysis.
The dynamic dynamic analysis system of complete sphygomanometer should comprise two parts: i.e. ambulatory blood pressure emulator and sphygomanometer adapter.These two devices are coupled together the dynamic property of measuring and analyze sphygomanometer by computer.
Summary of the invention
This patent has been invented a kind of sphygomanometer kinetic analyzer, has designed the ambulatory blood pressure emulator of simulation human blood-pressure dynamic change, and the blood pressure that this ambulatory blood pressure emulator can apply emulation for the sphygomanometer airbag is used to measure and analyze the characteristic of sphygomanometer.

Specific embodiments
The ambulatory blood pressure emulator buries the emulation blood vessel of putting one or more among Fig. 1 in emulation arm, wrist, also can put or not blood-letting pipe outside it, and it is fixed to come as required.The blood vessel two ends connect by many communications and liaison junctor, and serial connection is impacted pump and pump in tremulous pulse emulation blood vessel, is used for producing in blood vessel network ambulatory blood pressure.The pump that produces constant pressure also can adopt a Pressure Actuated Device to replace.Its position also can be placed on and the homonymy that impacts pump.
Computer among Fig. 2 is being controlled the startup shutoff and the duty of electromechanical device by the Electromechanical Control circuit, and one of them is the electromagnetic valve in the sphygomanometer adapter, and two other is the pump in the ambulatory blood pressure emulator and impacts pump.Computer is also gathered emulation blood vessel and interior pressure and the dynamic pressure of airbag by two pressure transducers and supporting signal conditioning circuit and digital analog converter thereof.
The sphygomanometer adapter is used to connect sphygomanometer to be determined among Fig. 3, can also gather ambulatory blood pressure process in the airbag simultaneously, has been used for sphygomanometer is analyzed, compared and examines and determine.Its electromagnetic valve can save.Usually, in the detected sphygomanometer vent valve is arranged.
Implementation result
At first, the airbag with the sphygomanometer adapter is rolled on the emulation arm or wrist of ambulatory blood pressure emulator.Then, under computer program control, the pump of ambulatory blood pressure emulator applies a preset pressure in its blood vessel, the impact pump of ambulatory blood pressure emulator applies a default fluctuation pressure in its blood vessel, thereby has produced an ambulatory blood pressure process identical with human body in emulation arm or wrist.At last, start the blood pressure that sphygomanometer is measured the ambulatory blood pressure emulator, computer data acquisition is also analyzed data.
