Blood pressure is an important symbol whether health or not . it is significant to design intelligent sphygmomanometer which applied to both family member and doctor 因此，研制既适合家庭保健人员又适合专业人士智能型血压计具有重要的意义。
Calibration will be performed by applying known pressures to the sphygmomanometer under test , and thereby the sphygmomanometer is required to have a pressure inlet for pressure input 校正时血压计会引入已知的压力，所以被校正的血压计要有引入压力的接口。
Main products : bedsore prevention mattress , vertebra rebractor , mercurial sphygmomanometer , stethoscopes , oxygen regulator , effective nebulizer , health care case , forehead lens , etc . 主要产品:防褥疮床垫颈椎牵引器血压计表听诊器氧气吸入器雾化器保健箱额镜出诊箱等产品。
The sphygmomanometer both can be used simple blood pressure measure and be multifunctionally used through connected to a personal computer . it can save blood pressure wave , result , including doing real time analysis and retrospective analysis 对家庭保健人员来说可以记录每次血压测量的结果、显示每次血压的波形；可以借助于血压分析软件对自己血压的不正常进行原因分析，也可以通过网络连接网上医院进行求诊。
Abstract : a portable digital instrument for multi - using ( multi - parameter ) is introduced . it includes the function of vacuometer , atmospheric pressure altimeter , thermometer ( environment ) and pressuremeter ( for example the standard pressuremeter of sphygmomanometer calibration ) 文摘:介绍一种便携、数字式的多用途仪器，它具有真空度计、气压高度计、 （周围环境）温度计以及压力计(例如可作为校准血压计的标准器)等功能。
This article use pic singlechip " pic16f874 " as the sphygmomanometer ' s kernel , which is prevalent at present . pressure which blood oppress vein is translated to electric signal . through pic16f874 ' s a / d translation modul it is be transformed digital signal 本文以目前较为流行的pic单片机pic16f874为血压测量计的核心，利用motorola公司的压力传感器将血液对血管壁的压力转换为电信号，并送入单片机中集成的a d转换模块将血压信号转换为数字信号后进行显示、存储、传输等处理。
New methods for noninvasively detecting pulmonary pressure and left ventricular end - diastolic pressure manometer that measures megative pressure in mmhg was connected with the examined subject through a mask . the manometer is a remodeled sphygmomanometer for routine peripheral arterial blood pressure measurement that is market - available . the examined subjects were asked to carry out muller maneuver slowly so that the intrathoracic pressure decreases gradually while the blood flow of the right ventricular outflow tract observed with pulsed doppler echocardiography at the parasternal short - axis view of the great vessels in the two - dimensional echocardiography 肺动脉压和左室舒张末压无创测定新方法随机选取有肺动脉瓣返流受检者，根据我们提出的假说，人为地降低胸内压（附加胸腔负压） ，当降到肺动脉内压力等于或小于右室压时，肺动脉瓣即可开放，用多普勒超声心动图法可以探查到肺动脉瓣上的前向血流，此时的肺动脉压应该为附加胸腔负压的绝对值加上右室压。
