Description

A kind of novel intelligent sphygomanometer

Technical field

This utility model relates to the novel household medical instruments field, particularly relates to a kind of novel intelligent sphygomanometer.

Background technology

The Measurement accuracy of blood pressure is the prerequisite of dysarteriotony reason quantitative analysis.The factor that affects human blood-pressure is a lot, as volumetric blood, sclerosis of blood vessels degree, cardiac function, endocrine, motion, emotion etc., but which factor is arranged actually, and impact has muchly actually, must rely on the Measurement accuracy of blood pressure.If, but the bigger error of blood pressure measurement own is enough to cover these influence factors, the prerequisite of dysarteriotony reason quantitative analysis is fallen and has not been existed.The Measurement accuracy of blood pressure will provide important evidence for the treatment of cardiovascular and cerebrovascular disease.Dysarteriotony, mean the existence of cardiovascular and cerebrovascular disease usually, and on clinical medicine, pressure value is as important Human's health parameters, for the treatment of cardiovascular and cerebrovascular disease provides foundation.If but the blood pressure measurement bigger error, or even wrong measurement result, must cause the mistake of diagnosis, the mistake that must cause Therapeutic Method and take medicine.Current sphygomanometer adopts the intermittently sphygmomanometry such as Ke Shi sound method mostly, and these methods can only record measured's pressure value of a certain particular moment, generally only have two values of systolic pressure and diastolic pressure, the blood pressure of therefore can't continuous monitoring often fighting.

Although also occurred as Portable Electronic Blood Pressure Monitor in recent years, although can complete the measurement of blood pressure, but this Portable Electronic Blood Pressure Monitor is utilized micro air pump pressurization rubber pneumatic bag, each measurement all needs the process of a pressurization and decompression, exist bulky, add the decompression process and have the shortcomings such as the degree of accuracy of discomfort, pulse detection is low, and can detect only have index parameter of blood pressure.Monitor and realize certain economic results in society for the variation that meets health of people information, therefore need research and development can on limited hardware resource platform, realize the mancarried device of pulse pressure automatic signal detection and analysis.The continous way measurement method is Measure blood pressure continuously in a certain amount of time, it can detect often fight blood pressure and continuous arterial pressure waveform, extracts its calculation of parameter by arterial pressure waveform and goes out diastolic pressure and systolic pressure, there is no the process of pressurization, very hommization, and the pressure value of measuring is also very accurate.

Summary of the invention

The technical problem that this utility model mainly solves is to provide a kind of novel intelligent sphygomanometer, can avoid the anthropic factor in measuring process, more science is comfortable to make measuring process, and measurement result is more accurate, for further realizing monitoring in 24 hours and the remote monitoring condition that provides the foundation.

For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of novel intelligent sphygomanometer is provided, this novel intelligent sphygomanometer comprises acp chip module, signal condition module, LCD display, pulse transducer and power module, described acp chip module, signal condition module, LCD display, pulse transducer all are connected to power module, and described pulse transducer, signal condition module, acp chip module are connected successively with LCD display;

Preferably, described acp chip module adopts the TMS320F2812 chip to do acp chip;

Preferably, described signal condition module adopts the AD620 instrument amplifier;

Preferably, described pulse transducer is HK2000A type pulse transducer.

The beneficial effects of the utility model are: a kind of novel intelligent sphygomanometer of this utility model, improved the method that blood pressure detects, can pressurize by measuring the pulse of human body self, then calculate pressure value by calculating, avoided the anthropic factor in the measuring process, more science is comfortable to make measuring process, and measurement result is more accurate, for further realizing monitoring in 24 hours and the remote monitoring condition that provides the foundation.

The specific embodiment

Below in conjunction with accompanying drawing, to this utility model, preferred embodiment is described in detail, thereby so that the advantage of utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1 to Fig. 3, this utility model embodiment comprises:

A kind of novel intelligent sphygomanometer, this novel intelligent sphygomanometer comprises acp chip module 1, signal condition module 2, LCD display 3, pulse transducer 4 and power module 5, described acp chip module 1, signal condition module 2, LCD display 3, pulse transducer 4 all are connected to power module 5, and described pulse transducer 4, signal condition module 2, acp chip module 1 and LCD display 3 are connected successively; Described acp chip module 1 adopts the TMS320F2812 chip to do acp chip; Described signal condition module 2 adopts the AD620 instrument amplifier; Described pulse transducer 4 is HK2000A type pulse transducer.

During this utility model work, the blood pressure in human body starts to propagate and produce pulse wave along whole Arterial system from aortic root section with the form of ripple.Therefore, the propagation characteristic of pulse wave be with cardiovascular system in mechanics parameter change closely-relatedly, it not only is subject to the impact of heart, also is subject to the impact of the factors such as arteries characteristic, blood parameters, muscle, skin simultaneously.That is to say, a series of cardio-vascular parameters such as blood pressure, blood flow, vascular resistance, blood vessel elasticity and blood viscosity change, can be reflected in the amplitude and wave form varies of pulse wave, therefore study the mutual relation between pulse characteristics parameter and blood pressure, according to the relatively judgement of the pulse wave of normal health situation and abnormal disease situation, just likely by cardiovascular disease potential danger be diagnosed as early as possible; Need not pressurize, by sensor, detect pulse wave, then according to waveform parameter, by corresponding algorithm, calculate diastolic pressure and systolic pressure, show on LCD display.

The novel a kind of novel intelligent sphygomanometer of this utility model, improved the method that blood pressure detects, can pressurize by measuring the pulse of human body self, then calculate pressure value by calculating, avoided the anthropic factor in the measuring process, more science is comfortable to make measuring process, and measurement result is more accurate, for further realizing monitoring in 24 hours and the remote monitoring condition that provides the foundation.This intelligent sphygmomanometer has adopted this chip of TMS320F2812, can well carry out filtering and fourier series matching to signal.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
