Abstract

The invention discloses a blood pressure monitor, which consists of a blood pressure sensor and a main machine, wherein the blood pressure sensor is a pressure or vibration sensor for sensing the pulse (pressure or vibration) of the artery of a human body on the surface of the human body and outputting a corresponding electric signal. The main machine is used for processing, analyzing and computing an electric signal output by the blood pressure sensor to obtain the value of the blood pressure. Compared with the conventional sphygmomanometer, the blood pressure monitor has the characteristics that: a booster air pump is not required; and the pulse signal of the artery on the surface of the human body is acquired in a normal state and the pulse signal is analyzed and computed to obtain the value of the blood pressure. The blood pressure monitor solves the problems of needing inflation, lacking continuous working capability, making a user discomfort of the conventional sphygmomanometer are solved, has the advantages of simple use, continuous working capability and real-time processing of monitoring results, and is very suitable for continuously monitoring blood pressure for a long time.

Description

A kind of monitoring of blood pressure instrument
[technical field]
The present invention relates to the monitoring of blood pressure technical field, be specifically related to a kind of novel monitoring of blood pressure instrument, this monitoring of blood pressure instrument need not to add compression pump, can be used in long-term continuous blood pressure monitoring.
[background technology]
Non-invasive blood pressure measuring method of the prior art has auscultation and oscillographic method.Auscultation is by listening Ke's formula sound to differentiate systolic pressure, diastolic pressure, and its reading is subjected to doctor's emotion, audition, environment noise, measured's the influence of series of factors such as anxiety, easily introduces subjective error.Present electric sphygmomanometer has adopted oscillographic method, differentiates blood pressure by the relation of setting up systolic pressure, diastolic pressure, mean pressure and cuff pressure Sasser.These two kinds of methods all need at first cuff to be inflated when measuring blood pressure, therefore, are not easy to carry out long-term continuous blood pressure monitoring.
[summary of the invention]
Main purpose of the present invention provides a kind of monitoring of blood pressure instrument that need not to add compression pump, can carry out long-term continuous blood pressure monitoring.
Technical solution of the present invention is:
A kind of monitoring of blood pressure instrument is made up of pressure transducer and main frame.Described pressure transducer is pressure or shaking sensor, is used to respond to beating of body surface tremulous pulse, and exports the corresponding signal of telecommunication.Described main frame comprises signal conditioning circuit, A/D change-over circuit, microprocessor and liquid crystal display screen.
Further, described signal conditioning circuit is used for that the output signal of telecommunication to described pressure transducer amplifies, Filtering Processing, obtains pulse signal.Described A/D change-over circuit changes this pulse signal into digital signal, carries out analytical calculation by described microprocessor, obtains pressure value, shows by liquid crystal display screen.
The invention has the beneficial effects as follows:
1, continuous operation.Do not inflate when this monitoring of blood pressure instrument does not need to measure in advance, can measure incessantly.
2, monitoring in real time.This monitoring of blood pressure instrument is gathered the signal of beating of body surface tremulous pulse in real time, and handles in real time and analytical calculation obtains monitoring result, demonstration in real time on liquid crystal display screen.
3, easy to use.This monitoring of blood pressure instrument does not need to inflate, and only need paste a pick off at wrist and get final product, and can pick off be fixed on wrist by comfortable elastic fabric yet.
[specific embodiment and description of drawings]
The application's feature and advantage will be by embodiment, in conjunction with the accompanying drawings.
Fig. 1 is the sketch map that the present invention recommends a kind of pressure transducer of selecting for use, is made up of shell, lead-in wire, upper/lower electrode and high polymer piezoelectric material, and high polymer piezoelectric material is filled between top electrode and the bottom electrode.This pressure transducer can be made the thin film that arbitrary shape and area do not wait as required.
Fig. 2 is the structural representation of monitoring of blood pressure instrument of the present invention, is made up of pressure transducer and main frame, and main frame comprises signal conditioning circuit, A/D change-over circuit, microprocessor and liquid crystal display screen.Pressure transducer is used to respond to beating of body surface tremulous pulse, and exports the corresponding signal of telecommunication.Signal conditioning circuit to this signal of telecommunication amplify, Filtering Processing, obtain the pulse signal of wrist.The A/D change-over circuit changes this pulse signal into digital signal, carries out analytical calculation by microprocessor, obtains pressure value, shows by display screen.
Fig. 3 is the long-term continuous blood pressure monitoring system schematic that adopts this monitoring of blood pressure instrument, and pressure transducer adopts film like piezoelectric transducer shown in Figure 1.This pick off can directly stick on wrist, also can be fixed on wrist by comfortable elastic fabric.Beating of pressure transducer induction wrist tremulous pulse exported the corresponding signal of telecommunication, and the processing and the analytical calculation of process main frame draw pressure value.
Above content be in conjunction with a kind of embodiment to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
