Along with the development of hospital modernization and domestic medicine service and tele-medicine, handheld device is applied in medical treatment more and more, such as, panel computer or smart mobile phone.How to realize communicating by letter between electric sphygmomanometer and smart machine, become the developing important topic of sphygomanometer.
The utility model content
This utility model is intended to propose a kind of electric sphygmomanometer that possesses the Bluetooth transmission function, utilize present smart machine or computer etc. usually to have the characteristics of bluetooth communication capability, realize communicating by letter between electric sphygmomanometer and smart machine or computer, the blood pressure data that sphygomanometer is detected sends to smart machine or computer terminal is stored, shows or processes.
The electric sphygmomanometer that possesses the Bluetooth transmission function of the present utility model comprises: power supply, on-off circuit, control unit, pressure transducer, bluetooth unit, air pump, vent valve, cuff; Power supply, on-off circuit, mu balanced circuit, control unit, pressure transducer, bluetooth unit, air pump, vent valve, cuff; Power supply is connected to pressure transducer, control unit, bluetooth unit after via on-off circuit and mu balanced circuit; Pressure transducer, air pump, vent valve, bluetooth unit are connected with control unit respectively; Air pump is controlled by control unit and is the cuff inflation; Vent valve is controlled by control unit and the gas in cuff is emitted; Pressure transducer is used for the pressure of sensing cuff inside; Pressure transducer is delivered to control unit with the pressure data that records; Control unit will be delivered to bluetooth unit from the pressure data that pressure transducer receives; Bluetooth unit will certainly be controlled the pressure data that the unit receives and send to the outside.
Preferably, described pressure transducer is the MMR901 load cell of MITSUMI company.
Preferably, further comprise the OLED display unit, be connected to described control unit, the pressure data that indicative control unit receives.
Preferably, described bluetooth unit is bluetooth 4.0 transport modules.
The electric sphygmomanometer that possesses the Bluetooth transmission function of the present utility model can be with bluetooth approach easily and carry out Bluetooth communication between panel computer, PDA, smart mobile phone or computer, conveniently blood pressure data is sent to panel computer, PDA, smart mobile phone or computer shows, stores or process.Because the electric sphygmomanometer that possesses the Bluetooth transmission function of the present utility model has adopted the MMR901 load cell, possess the good advantage of pressure and the magnitude of voltage linearity, and solved each problem of calibrating respectively of the poor needs of concordance between existing sphygomanometer.
Description of drawings
From the following description to preferred embodiments and drawings that purport of the present utility model and use thereof are described, above and other objects, features and advantages of the present utility model will be apparent, in the accompanying drawings:
Fig. 1 is the principle assumption diagram that possesses the electric sphygmomanometer of Bluetooth transmission function of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the electric sphygmomanometer that possesses the Bluetooth transmission function of the present utility model is described in detail.
As shown in Figure 1, the electric sphygmomanometer that possesses the Bluetooth transmission function of the present utility model mainly comprises pressure transducer, control unit, bluetooth unit.Here, control unit can be single-chip microcomputer, DSP or other processor with I/O function.Power supply is respectively pressure transducer, control unit, bluetooth unit power supply after via on-off circuit and mu balanced circuit.Here, on-off circuit refers to electrical switch or electric switch.
Control unit is connected to air pump and vent valve, controls air pump and vent valve and cuff is inflated or exitted.When needing inflation, control unit sends the inflation instruction to air pump, and air pump is started working, and inflates to cuff.When needs were exitted, control unit sent the venting instruction to vent valve, and vent valve is started working, and cuff is communicated with outside, and the cuff internal gas is discharged to the outside.Here, although do not draw, those skilled in the art should be understood that air pump and vent valve all drive by drive circuit.
Pressure transducer is used for measuring the pressure in cuff, is in particular pressure transducer and is communicated with cuff by trachea.The blood pressure data that pressure transducer measures is delivered to control unit.What select here, is the MMR901 load cell of MITSUMI company.It is high that this sensor has integrated level, and the linearity between pressure and voltage is high, and whole MMR901 load cell is chip piece, and therefore, the concordance of product is better, do not need to resemble existing pressure transducer respectively with hardware mode Circuit tuning parameter.
Control unit can transmit described pressure data to bluetooth unit, sends pressure data by bluetooth unit to the outside, carries out communication with external equipment, as panel computer, smart mobile phone, computer, PDA etc.Here, bluetooth unit can be bluetooth 2.0 transport modules, can be also bluetooth 3.0 transport modules or bluetooth 4.0 transport modules.Be preferably bluetooth 4.0 transport modules.
Control unit can also be connected with display unit, is preferably the OLED display unit, to show pressure data.
During use, cuff is wrapped in person's to be tested upper arm, the turn on-switch circuit is sent out to air pump by control unit and is inflated instruction, and air pump begins to inflate to cuff, beats when subscribing pressure, and air pump quits work.Pressure in the pressure sensor senses cuff is delivered to control unit with the pressure data that records, and control unit is delivered to bluetooth unit with pressure data, has bluetooth unit that pressure data is transferred to external equipment.Control unit can demonstrate it after receiving pressure data in the OLED display unit.After completing surveying work, control unit sends instruction to vent valve, and vent valve is released to the gas in cuff in atmosphere after connecting.
Cuff during this use is novel refers to the cuff with air bag, is the cuff cuff that is used for sphygomanometer of routine.
Although illustrated and described the preferred embodiments of the present invention, it is contemplated that, those skilled in the art can design various modifications of the present utility model in spirit and scope of the present utility model.
