Abstract
The utility model belongs to a novel medical instrument, which is an intelligentized instrument. The utility model has both functions of an automatic blood-pressure meter and a dynamic electrocardio-monitor. The instrument is controlled by a computer central processor, proceeding to measure blood pressure and heart rate, which analyzes and processes the electrocardio-signals and stores the signals into a solid state memory. The amplifier of electrocardio-signals and blood pressure signals has the characteristics of automatic gain control and filters. The synchronous real time data of blood pressure, electrocardiograms and heart rate within the 24 hours are monitored in the free activity of patients. The utility model adopts printers, monitors and microcomputers to replay the information and the complete instrument adopts a CMOS large scale integration. The utility model has the advantages of low power consumption, high reliability and convenience for carrying.
Description
This utility model belongs to Medical Instruments
Existing ambulatory blood pressure monitoring instrument only carries out independent monitoring to patient's blood pressure information, and single blood pressure data is provided.Existing dynamic electrocardioscanner also only carries out independent monitoring to patient's ecg information, and single electrocardio data also only is provided.These two kinds of dynamic monitoring instruments all can not be synchronous blood pressure and Electrocardiographic real-time monitoring materials be provided.And blood pressure and ECG information are closely-related physiologic informations.Provide asynchronous blood pressure and two kinds of data of electrocardiogram when providing real-time, synchronous blood pressure and ecg data to want score, clinical diagnosis is had prior meaning.It is the difference that essence is arranged that the real time data of blood pressure and electrocardiogram synchronization gain is compared with asynchronous blood pressure and two kinds of data of electrocardiogram.Synchronous blood pressure and electrocardiogram real time data reflect the objective variation of these two kinds of relevant informations really, not only make things convenient for the doctor, handle the diagnosis data, and main is associated change and the intrinsic contact that the doctor obtains blood pressure and electrocardio two aspect information.More valuable to clinical diagnosis.This is the advantage that existing ambulatory blood pressure monitoring instrument and dynamic electrocardioscanner do not possess.
The purpose of this utility model
Provide real-time synchronous monitoring patient's blood pressure of a kind of energy and Electrocardiographic instrument--ambulatory blood pressure electrocardio and heart rate comprehensive monitor, the active patient of freedom is carried out 24 hours monitoring of whole day provides real-time blood pressure and the synchronous data of electrocardio (comprising heart rate), as the important evidence of doctor's clinical diagnosis, direction of medication usage, observe the curative effect, the capsule information that give emergency treatment to a patient and medical research.
This utility model is to be controlled by central processing unit, and blood pressure, electrocardio and heart rate signal are amplified, and is transformed into digital signal through A/D, is stored in the solid memory.The playback data is exported through equipment such as display, printers through the standard I-O interface circuit.Central processing unit rationally and dexterously is combined into one automatic sphygmomanometer and dynamic electrocardiogram instrument, constitutes intelligentized comprehensive monitor.Wherein dynamic electrocardiogram instrument structural shape is identical with " dynamic ecg monitoring device " (88214533.9 applyings date 880927 of the patent No.).Complete machine adopts the CMOS integrated circuit, and consumed power is few, does not have mechanical wear and problem of aging.Volume is little in light weight, and is easy to carry, the reliability height.Remove and to utilize printer, drawing apparatus playback, all right and microcomputer network.
