Abstract

The utility model relates to an improved design for a cardiac module, which is characterized in that the blood-pumping function of the cordis is displayed by utilizing the flow of the liquid in a simulated cordis via nonreturn valve structures arranged at the juncture of the atrium-shaped cavity and the ventricle-shaped cavity and the juncture of the starting end of the arterial canal and the ventricle-shaped cavity. The nonreturn valve structures can completely simulate the setting of the cardiac valve shape. The utility model has the advantages of low cost, simple operation. The cardiac module can visually display the pumping blood process and the physiological mechanism of the cordis, and solves the difficulties and the key points in the teaching.

Description

Blood function demonstrator of heart pump
The utility model is about a kind of human organ type teaching demonstration device.
At present the used teaching aid in biology teaching in junior middle school aspect is with the model of static state, wall chart is main, not lively, only manifest form and structure and probably can not demonstrate the biosome physiological function, we also once designed a kind of heart collecting moving and blood-circulation model, the patent No. is 89206481.1, it on the structure activity of controlling heart with a sheave, before go a step further than static model, can demonstrate the cardiac cycle of heart, blood flow direction and blood circulation approach in the chambers of the heart can be manifested with the light that flashes, but still the authentic activity state and the valve bascule mechanism of inner each function of the chambers of the heart can not be demonstrated.
The purpose of this utility model is will overcome the defective that prior art exists and provide a kind of chambers of the heart of simulating fully movable and can intuitively show the cardiac pumping function demonstration device of its cardiac pumping physiology course and physiological Mechanism.
This cardiac pumping function demonstration device utilizes liquid to flow in the heart in simulation to show the cardiac pumping function, has flexible matrix simulation ventricle, shape chamber, atrium, moving, duct of Arantius, architectural features such as base plate are installed, characteristics of the present utility model are to be provided with one-way valve structures at shape chamber, atrium and ventricle shape chamber intersection and arterial top and ventricle shape chamber intersection, atrium and the ventricular contraction and the diastole activity of the manual extruding of operation demonstrator action simulation heart, make each retaining valve open and close liquid in the simulation heart from atrium → ventricle → artery folk prescription to flowing, solved and be difficult to difficult point and the emphasis demonstrating and explain in the present teaching, thoroughly changing in the past, the student can only listen the teacher to say, the phenomenon that the contrast books are memorize mechanicallyd, even learning, the student understands, learn logical, learn and live, be convenient to teacher's explanation again, demonstration.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is a cardiac pumping function demonstration device example structure view.
As shown in the figure, the present embodiment cardiac module only is the left half side of normal human's heart, shape chamber, atrium (8) is made by rubber-plastics material with ventricle shape chamber (1), the contraction diastole activity of atrium and ventricle is simulated in available manual extruding action, moving, duct of Arantius (5,6) make by glass-tube and be convenient to observe the liquid flow situation, shape chamber, atrium (8) and ventricle shape chamber (1), ventricle shape chamber (1) can be the marble spring structure with the retaining valve of arterial (5) top intersection setting, it also can be the retaining valve plug structure that flexible sheet constitutes, and the one-way valve structures in the present embodiment is also simulated the setting of cardiac valves features of shape, be that shape chamber, atrium (8) is made of two to three membranaceous flexible membranes of cusp (9) with the retaining valve that ventricle shape chamber (1) intersection is provided with, diaphragm (9) extends in the ventricular chamber lower end and is fixed on prominence (11) from the atrium inwall and is inverted triangle strainer shape, this prominence (11) is equivalent to the papillary muscle structure, and the retaining valve that is provided with arterial (5) top intersection in ventricle shape chamber (1) is made of the artery flap bag film (4) that three openings make progress, abide by the setting of human heart model fully and then be adjacent to sealing mutually during three artery flap bag films (4) liquid turgor, three bag films (4) lower end combination of shapes is umbrella shape and opens.It is true to nature in the true heart planform that above-mentioned one-way valve structures is provided with shape, hereby in shape chamber, atrium (8), ventricle shape chamber (1) and arterial (5) top intersection cut a mouth, and seal by translucent cover (2), also available fluid sealant gummed beyond derivet (3) clenches, locate to be provided with a tensimeter (10) in ventricle shape chamber (1) and be connected the variation that can directly show the ventricular chamber internal pressure with it, installing plate among the figure (7) is used for fixing to install to be used.The present embodiment demenstration method is described below according to the bioconversion medium term:
From " pulmonary vein " to half " heart " perfusion fluid, liquid reaches at " pulmonary vein " respectively certain altitude in " sustainer ", the demonstrator pushes " ventricle " tip with manual control, the simulation ventricular contraction, make " ventricle " interior voltage rise height, owing to fill liquid in " heart " chamber, this moment, liquid upwards impacted " atrioventricular valve ", make " atrioventricular valve " front and back two or three jam-packeds, opening between the sealing " atrium " and " ventricle ", the simulation ventricular contraction, intraventricular pressure raises, when intraventricular pressure during greater than atrial pressure, atrioventricular valve is closed.Strengthen pinching power, make to press more in " ventricle " and raise, then three bag shapes " arterial valve " of original full of liquid are extruded by liquid, bag is flattened, and promptly " arterial valve " opened, and liquid level rises at this moment visible " sustainer " glass-tube, the simulation ventricular contraction, intraventricular pressure is during greater than angiosthenia, and arterial valve is opened, and main liquid is by ventricle → artery, gradually unclamp ventricle, the simulation ventricular diastole, intraventricular pressure reduces, when being reduced to a certain degree, fill with liquid in three bags of " arterial valve ", three free surfaces paste mutually, sealing artery internal orifice, and the simulation arterial valve is closed.The hand of pinching " ventricle " continues to loosen, and makes to press in " ventricle " to continue to descend, and (is lower than intra-atrial pressure) when being reduced to a certain degree, two are opened before and after " atrioventricular valve ", the simulation atrioventricular valve is opened, and blood is by atrium → ventricle, and this moment, the liquid level of visible " pulmonary vein " glass-tube descended.Pressure gauge can be observed the variation of " intraventricular pressure ".The utlity model has following advantage:
Cost is low; Simple to operate; Can show cardiac pumping process and physiological Mechanism thereof intuitively, solve difficult point, the emphasis in the teaching; Class demonstration, review after class all can be used (but because repetitive operation).
