便携式血压计的设计

摘 要

现代社会的迅速发展，导致环境日益恶化，不健康的生活习性与不科学的饮食习惯，导致人类疾病越来越多的出现。其中，有着人类第一无形杀手称号的高血压病，已逐渐上升到人类疾病危害排行榜的前几名，长期危害着人体健康，让饱受高血压折磨的患者痛不欲生。如何便捷有效地测量与监控高血压，从而有效预防与治疗高血压，成为人们对抗高血压病的首要问题。于是，设计一台便捷的测量血压的装置，成为重中之重。
家用电子血压计，主要是用于家庭。家庭医疗保健已成为现代人的医疗保健时尚。过去人们测量血压必须到医院才行，而今只要拥有了家用电子血压计，坐在家里便可随时监测血压的变化，如发现血压异常便可及时去医院治疗，起到了预防脑出血、心功能衰竭等疾病猝发的作用。本文将详细介绍我们设计的智能型血压测量装置。

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.
