便攜式血壓計(jì)的設(shè)計(jì)

摘 要

現(xiàn)代社會(huì)的迅速發(fā)展，導(dǎo)致環(huán)境日益惡化，不健康的生活習(xí)性與不科學(xué)的飲食習(xí)慣，導(dǎo)致人類疾病越來(lái)越多的出現(xiàn)。其中，有著人類第一無(wú)形殺手稱號(hào)的高血壓病，已逐漸上升到人類疾病危害排行榜的前幾名，長(zhǎng)期危害著人體健康，讓飽受高血壓折磨的患者痛不欲生。如何便捷有效地測(cè)量與監(jiān)控高血壓，從而有效預(yù)防與治療高血壓，成為人們對(duì)抗高血壓病的首要問(wèn)題。于是，設(shè)計(jì)一臺(tái)便捷的測(cè)量血壓的裝置，成為重中之重。
家用電子血壓計(jì)，主要是用于家庭。家庭醫(yī)療保健已成為現(xiàn)代人的醫(yī)療保健時(shí)尚。過(guò)去人們測(cè)量血壓必須到醫(yī)院才行，而今只要擁有了家用電子血壓計(jì)，坐在家里便可隨時(shí)監(jiān)測(cè)血壓的變化，如發(fā)現(xiàn)血壓異常便可及時(shí)去醫(yī)院治療，起到了預(yù)防腦出血、心功能衰竭等疾病猝發(fā)的作用。本文將詳細(xì)介紹我們?cè)O(shè)計(jì)的智能型血壓測(cè)量裝置。

THE DESIGN OF PORTABLE BLOOD PRESSURE MONITOR

ABSRACT

The rapid development of modern society, leading to deteriorating environment, unhealthy living habits and unscientific eating habits, leading to the emergence of an increasing number of human diseases. Which has one invisible killers of the human hypertension, and has gradually risen to the top ranks of human disease, a long-term hazard to human health, so that patients suffering from hypertension pain. How convenient and effective measurement and monitoring hypertension, and thus effective prevention and treatment of hypertension, a confrontation hypertension is the most important issue. Therefore, design a convenient measurement of blood pressure devices, has become a priority. This article will detail the design of our intelligent blood pressure measuring devices.
Home Blood Pressure Monitor, mainly for home. Home health care has become a fashionable modern health care. Measuring blood pressure in the past people have to go to the hospital for the job now as long as the electronic blood pressure monitor has a home, sit at home monitoring of blood pressure can be at any time, such as abnormal blood pressure can be found in time to the hospital for treatment, prevention plays a cerebral hemorrhage, heart failure The role of diseases such as burst.
