Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
From Fig. 1 and Fig. 2, the sphygomanometer of the present embodiment comprises blood pressure measurement module, data acquisition transport module, smart mobile phone control treatment display module.Smart mobile phone end sends instruction to single-chip microcomputer (being preferably STM32 single-chip microcomputer in the present embodiment) by bluetooth, Single-chip Controlling air-pump inflating, simultaneously pressure transducer is started working, and closes, start venting and image data when pressure transducer records air pump when pressure reaches 200mmHg.Data are turned round and stretched out the hand machine by Bluetooth transmission by single-chip microcomputer.Mobile phone terminal also demonstrates waveform in real time by software parses data, and pressure transducer records pressure to be stopped gathering lower than single-chip microcomputer during 40mmHg, and gather and terminate, mobile phone terminal software demonstrates pressure value, and just provides some of the recommendations according to blood pressure.Mobile phone terminal software, with the function of preservation data, can be selected this locality to preserve and also can select send shared with the doctor of oneself stored in high in the clouds or social software or supply oneself to contrast for a long time.
As shown in Figure 1, the blood pressure measurement module of the present embodiment comprises cuff, air pump, vent valve and pressure transducer, and wherein cuff is connected with pressure transducer with air pump, vent valve respectively.Air-pump inflating terminates rear vent valve and starts venting, and pressure transducer starts Measure blood pressure data.
As shown in Figure 3, be the mixed signal of pulse signal and static pressure signal from pressure transducer signal out, be also mingled with from the High-frequency Interference in the external world and direct current or low frequency component.Static pressure signal belongs to low frequency signal, and frequency is less than or equal to 0.04Hz, and pulse signal frequency is generally about 1Hz.Although pressure transducer can have enlarging function, limited to the amplification of pulse oscillator signal, therefore mainly static pressure signal.Mixed signal is divided into two parts.One tunnel is directly connected to STM32 Chip Microcomputer A/D C acquisition port 1, obtains static pressure signal data; Separately lead up to 40Hz low-pass filtering amplifying circuit with extraneous High-frequency Interference such as elimination arm and cuff frictions, again by 0.4Hz high pass filter elimination low-frequency disturbance, finally by 100 times of amplifying circuits, the pulse signal data cube computation be amplified is to STM32 Chip Microcomputer A/D C acquisition port 2.
As shown in Figure 4, HK4100F relay is preferably selected in air pump control circuit in the present embodiment, the base stage B of PNP type triode receives the I/O mouth 1 of STM32 single-chip microcomputer bluetooth module, the emitter E of audion receives one end of relay coil, the other end of coil is received on the power supply of+5V, the two ends of relay coil also meet a diode IN4148, the inverse electromotive force produced during for absorbing release relay coil blackout, prevent reverse potential from puncturing audion and disturb other circuit; Resistance Rf2 and LED form a relay status indicating circuit, and when relay adhesive time, LED diode is lighted, and so just can see air-pump inflating state intuitively.
When single-chip processor i/o mouth sends high level, relay adhesive, LED diode is lighted, and air pump starts inflation, and pressure transducer is synchronously started working when air pump is started working.Send low level when recording single-chip processor i/o mouth when static pressure reaches 200mmHg, relay disconnects, and LED diode extinguishes, and air pump stops inflation, and single-chip microcomputer starts to gather blood pressure data and is sent to mobile phone terminal by bluetooth simultaneously.
In the present embodiment, data acquisition transport module STM32 single-chip microcomputer and an integrated gained of bluetooth module.This module has two ADC acquisition port and two I/O mouths, and ADC acquisition port gathers static pressure signal and pulse wave signal respectively, and I/O mouth is used for controlling air pump.Signal is sent to bluetooth module by serial communication by single-chip microcomputer, then is sent to mobile phone terminal by Bluetooth wireless transmission.
Present mobile phone charging interface is all Micro USB substantially, carries unnecessary charger to not increase user, can power with upper module by direct current 5V Micro USB, namely directly adopts charger for mobile phone to power.
Data by receiving in the present embodiment can be sent to the external treatment system such as portable client (such as smart mobile phone) be connected with single-chip microcomputer and carry out Data Analysis Services and shown by graphical data.
Can be such as that bluetooth is connected or other modes connect with the connected mode of external treatment system.
Data calculated by the algorithm editted, namely can obtain systolic pressure and the diastolic pressure of measured, the data collected, also with functions such as data preservations, can be saved in this locality and check for contrast by software.
This utility model also has replaceability.As long as the smart mobile phone with Bluetooth function can be installed compiled software and communicate with slave computer and carry out blood pressure measurement, provide very large convenience and versatility.
Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
