Portable blood pressure monitor

Abstract

The invention provides a portable blood pressure monitor which comprises a microcontroller, a Bluetooth communication module, a power module, a clock module, a pressure sensor module, a driving circuit module and an amplification circuit module. The pressure sensor module completes conversion of air pressure signals to pressure signals and generates voltage signals, and after the voltage signals are amplified and modulated by the amplification circuit module, two paths of analog quantity signals of pulse wave signals and sleeve band static pressure are obtained and then transmitted to the microcontroller; the microcontroller processes and stores the pulse wave signals and the sleeve band static pressure, and the Bluetooth communication module and a short distance wireless communication module provide transmission and / or reading of information; the short distance wireless communication achieves normal reading and transmission of blood pressure information under the condition of powering on / powering off and network availability / network unavailability. An existing display screen is omitted, the weight and size of equipment are greatly reduced, portability is improved, information reading and transmission can also be carried out under the condition of network unavailability, and the portable blood pressure monitor is more convenient to use.

Description

technical field [0001] The invention relates to a medical device for detecting blood pressure, in particular to a portable blood pressure detection device with wireless communication function. Background technique [0002] With the development and progress of science and technology, smart wearable devices are showing a trend of rapid development year by year. In 2012, the market size of mobile medical care has reached 1.86 billion yuan. It is estimated that by 2017, the market size of China's mobile medical care will reach 12.5 billion yuan. At present, China's mobile medical industry is in a state of development, and the field of mobile medical applications has a broad imagination space. [0003] On the other hand, with the continuous improvement of people's living standards, people pay more and more attention to health. Especially among the elderly, the incidence of high blood pressure is extremely high. Most empty-nest elderly not only do not have the habit of measuring b...

Problems solved by technology

However, the patent mainly emphasizes the communication method based on the protocol, and does not emphasize the performance and portability of the blood pressure device, nor does it emphasize the power consumption of the device and the specific transmission method

In addition, the device relies on the Internet and does not have certain effectiveness, and it cannot complete the synchronization of the information of the blood pressure instrument on the mobile terminal without the network and power supply
