Abstract
The invention discloses a continuous blood pressure measurement device consisting of a pulse sensor and a mainframe, wherein the pulse sensor is a piezoelectric film sensor used for collecting pulse signals of a human body; and the mainframe is used for carrying out process and analysis computation on output signals of the pulse sensor to obtain the blood pressure value. The continuous blood pressure measurement device disclosed by the invention solves the problems that the current sphygmomanometer needs a pressure air pump, does not have continuous working capability and is easy to make a user uncomfortable, has the advantages of simpleness in use, capability of continuous working and capability of processing measurement results in real time, and is very suitable for being applied to long-term and continuous blood pressure measurement.
Description
[technical field]
The present invention relates to the blood pressure measurement technical field, be specifically related to a kind of novel blood pressure measuring device, need not to add compression pump, can be used in long-term continuous blood pressure monitoring.
[background technology]
The lateral pressure that when blood pressure refers to that blood flows in blood vessel blood vessel wall is applied, it is the important physical signs of reflection cardiovascular function.Blood pressure measurement mainly adopts cuff formula electric sphygmomanometer at present, and need add compression pump and come the cuff inflation, and can only the single measurement pressure value.Owing to human blood-pressure along with physiological period, personal mood, the external world and inherent various stimulations change, have tangible undulatory property, so the single measurement blood pressure has occasionality, can not reflect the change situation of human blood-pressure value and blood pressure exactly.And continuous blood pressure is measured variation and the rule that can reflect blood pressure, has great importance in clinical and medical research.
[summary of the invention]
Main purpose of the present invention provides a kind of blood pressure measuring device that need not to add compression pump, can carry out long-term continuous blood pressure measurement.
Technical solution of the present invention is:
A kind of continuous blood pressure measuring device is made up of pulse transducer and main frame.Described pulse transducer is piezoelectric film sensor, is used for the pulse of induction human body, and exports the corresponding signal of telecommunication.Described main frame comprises signal conditioning circuit, microprocessor and the liquid crystal display screen that connects successively.The outfan of described pulse transducer is connected with the input of described signal conditioning circuit.
Further, described signal conditioning circuit is used for the output signal of telecommunication of described pulse transducer is amplified and Filtering Processing, obtains pulse signal.Described microprocessor extracts characteristic parameter from the output pulse signal of described signal conditioning circuit, goes out pressure value according to calculation of characteristic parameters then.
The invention has the beneficial effects as follows:
1, continuous operation.Do not inflate when this blood pressure measuring device does not need to measure in advance, can measure incessantly.
2, measure in real time.This monitoring of blood pressure instrument is gathered the pulse of human body in real time, and handles in real time and analytical calculation obtains measurement result, demonstration in real time on liquid crystal display screen.
3, easy to use.This blood pressure measuring device does not need to inflate, and only need paste a sensor at wrist and get final product, and can sensor 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 of blood pressure measuring device of the present invention, is made up of pulse transducer and main frame, and main frame comprises signal conditioning circuit, microprocessor and liquid crystal display screen.Pulse transducer is used for the pulse of induction human body, and exports the corresponding signal of telecommunication, signal conditioning circuit to this signal of telecommunication amplify, Filtering Processing, obtain pulse signal, carry out analytical calculation by microprocessor again, obtain pressure value, show by display screen.
Fig. 2 is the use sketch map of this blood pressure measuring device, and pulse transducer can directly stick on wrist, also can be fixed on wrist by comfortable elastic fabric.Pulse transducer is wired to main frame, and main frame enters to handle and analytical calculation to the output signal of pulse transducer, obtains pressure value.
Above content be in conjunction with a kind of embodiment to further describing that the present invention does, 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.
