Description
Technical field
the utility model relates to a kind of controlling of blood pressure device, especially a kind of heart blood circulation experiment controlling of blood pressure device.
Background technology
the causing circulatory of human body comprises heart, blood vessel and lymphatic system, between them, interconnect, form " piping system " for sealing substantially, its cardiac is for driving sanguimotor motive power, blood vessel comprises artery, vein, blood capillary, wherein systemic arterial blood pressure is called for short blood pressure (blood pressure, BP).Blood pressure is blood while flowing in blood vessel, the wall pressure that unit area vascular wall is applied, and it is to promote blood mobile power in blood vessel.Ventricular contraction, blood flows into artery from ventricle, and now blood is the highest to the pressure of artery, is called systolic pressure (systolic blood pressure, SBP); Ventricular diastole, arteries elastical retraction, blood still slowly continues to flow forward, but blood pressure drops, pressure is now called diastolic pressure (diastolic blood pressure, DBP).Normal heart is as a strong muscular organ, just as a water pump, it around the clock, have the rhythm and pace of moving things and beating, one one contracting of heart streams past in an endless flow blood in causing circulatory.When blood flows in blood vessel, no matter heart contraction or diastole, all produces certain pressure to vascular wall.Pressure when heart contraction in main artery is the highest, and blood is at this moment called " high pressure "; During LV Diastolic, the pressure in main artery is minimum, therefore be called " low pressure ".
normal blood pressure is the mobile prerequisite of blood circulation, and blood pressure keeps normal under many factors regulates, thereby provides each histoorgan with enough blood volumes, uses and maintains normal metabolism.Hypopiesia too high (low blood pressure, hypertension) all can cause serious consequence, and blood pressure disappearance is simultaneously dead omen, and this all illustrates that blood pressure has extremely important biological significance.
in medical teaching process, teacher often simulates the blood circulation of heart by pneumatic pump, but can only make the red liquid in heart blood circulation demonstrating model at the uniform velocity mobile by air pump, the low high variation of the blood pressure one that brings in the time of cannot simulating one contracting of heart, thereby the lively sense of shortage, make student understand difficulty, affect results of learning; Also there are some teachers to heart blood circulation demonstrating model, to inflate to simulate the variation of blood pressure by inflator manually, but inflation manually easily causes simulation high blood pressure low amplitude unstable, the low high variation of the blood pressure one that brings in the time of equally also cannot simulating one contracting of heart completely; Also there are some teachers to connect heart blood circulation demonstrating model by lung ventilator and simulate blood pressure change simultaneously, but along with one of lung ventilator is exhaled a suction, there is backflow phenomenon in the red liquid in heart blood circulation demonstrating model, the low high variation of the blood pressure one that brings in the time of also cannot simulating one contracting of heart.
Summary of the invention
the utility model object is: provide a kind of can the cyclic process of perfect simulation heart blood in the heart blood circulation experiment controlling of blood pressure device of human body actual blood pressure.

preferably, described simulation blood pressure amplitude device comprises the stepper motor being connected with described control device, the depression bar being connected with described stepper motor, and be located on described depression bar and along with depression bar swings up and down and the hollow elasticity spheroid that compresses, expand, the top of described hollow elasticity spheroid is communicated with described multiport valve.
preferably, described simulation blood pressure amplitude device is lung ventilator, and described lung ventilator is connected with described multiport valve by conduit.
preferably, this controlling of blood pressure device also comprises simulation blood pressure monitoring device, and described simulation blood pressure monitoring device is connected with described multiport valve by conduit or is connected with the outlet of described heart blood circulation demonstrating model by conduit.
preferably, described control device comprises single-chip microcomputer, and the control panel being connected with described single-chip microcomputer, and described single-chip microcomputer is connected with described pneumatic pump by a solenoid valve simultaneously.
more preferably, described solenoid valve is speed-regulating valve.
the utility model has the advantages that: this heart blood circulation experiment can perfectly be simulated human body actual blood pressure in heart blood cyclic process with controlling of blood pressure device, and vivid and interesting, facilitates student to understand, and improves results of learning.
