Description of drawings
Fig. 1 is the utility model simulation model of arteriovenous blood circuit circulating system structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated.
With reference to Fig. 1, simulation model of arteriovenous blood circuit circulating system is comprised of three parts: circuit control module, liquid road module, model person, described three parts connect successively, wherein
Circuit control module: comprise control circuit, keyboard, liquid crystal display shows, power supply.Control circuit is take AVR single chip computer AT MEGA32A as processing core, and whole function control and data are processed.The liquid crystal display demonstration is used for demonstration "current" model state, comprises pulse intensity and pulse frequency, and the user can arrange pulse intensity and frequency by keyboard.Power unit is taked entrance voltage 12V, and the 12V power supply can be used for turbine and solenoid valve, it is depressurized to 3.3V is used for the single-chip microcomputer power supply.
Liquid road module: comprise turbine, solenoid valve, liquid storage box and silicone tube.By circuit control turbine, the blood in the silicone tube is circulated with certain pressure, by the break-make of control solenoid valve, the realization pulse is beaten simultaneously.
Model person: this part is carried out the flexible pipe layout according to human body major arteries and venous locations, also can carry out layout according to customer requirements.At corresponding point of puncture, use silicone tube, simulate blood is arranged in the silicone tube, can guarantee on the one hand after the puncture not can leakage, on the other hand, and because its elasticity is better, the abundant emulation pulse effect of beating.
Principle of the present utility model is as follows:
Pulse is beaten: after by circuit control turbine being powered on, turbine is started working.In the situation that solenoid valve is opened, whole bloody path begins to circulate, behind shut electromagnetic valve, the bloody path circulation is blocked, but turbine is still in work, so that the blood pressure in the closed bloody path increases, with the emulsion tube jack-up of point of puncture, probably continue to open solenoid valve behind the 500ms, it is normal that endovascular pressure recovers, emulsion tube also resets by expanding into, thereby realizes the effect that pulse is beaten.
Pulse frequency: according to the realization principle of previous step, pulse frequency is the make-and-break time interval by the Timer Controlling solenoid valve in the adjustment single-chip microcomputer, thereby makes pulse frequency adjustable.
Pulse intensity/blood flow: this parameter is to be decided by endovascular pressure size.By changing secondary speed, realize the change of blood pressure size, secondary speed is faster, and pressure is larger in the bloody path, otherwise, less.Realize by the square-wave voltage of giving the certain dutycycle of turbine when changing secondary speed, dutycycle is larger, and secondary speed is faster, and dutycycle is less, and secondary speed is less.The dutycycle square wave is by the PMW circuit output of single-chip microcomputer.
The concrete steps of the utility model when concrete operations are:
The first step: with corresponding the linking to each other of artery and vein vascular of model person and liquid storage box, circuit is controlled power lead be inserted in the 220V supply socket.
Second step: with the Electronic Control Box power supply opening, after system powered on, liquid crystal display showed that main interface will show the title of this product and the Logo of Beijing Yimo Technology Co., Ltd..Then system's display interface that automatically gets the hang of.Displaying contents comprises: systolic pressure, diastolic pressure, heart rate, pulse intensity.The default value of heart rate and pulse intensity is respectively 60B/MIN, and 60%.System begins to start working according to the default setting value, and namely artery begins to beat with the frequency of 60 per seconds, beats with 60% of total intensity.Vein begins circulation.
The 3rd step: according to requirement of experiment, systolic pressure, diastolic pressure, heart rate, pulse intensity are adjusted.Method of adjustment enters the interface is set by keyboard ' setting ' key, presses continuously ' setting ' key again and can adjust the preset parameter.Adjust the parameter size by upper and lower key, cursor is adjusted to return press up and down that key can be back to state interface.
The 4th step: after parameter adjusted by requirement of experiment, can be according to the puncture requirement of step of medical science, the point of puncture of model person is carried out puncture procedure.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
