Description

A kind of fish blood circulation demonstration device

The utility model relates to a kind of bioconversion medium demonstration instrument, particularly a kind of fish blood circulation demonstration device.

At present in the bioconversion medium, when the blood circulation of explanation human body, animal, understand for ease of the student, generally teaching aid chromatic colour blood circulation wall chart of Cai Yonging and photoelectricity blood circulation demonstration device, from teaching efficiency for many years, colored blood circulation wall chart is inflexible, not vivid, lively, and it is not dark that the student learns the back impression; Though photoelectricity circulation demonstration device is vivid than wall chart, but because it is to replace flowing of blood with moving of photoelectricity, therefore there is feeling of unreality in the demonstration, in order to remedy these defectives of above-mentioned teaching aid, the someone had invented the blood circulation demonstration device of demonstrating the blood circulation process with flowing of red liquid successively in recent years, though the demonstration device progress that these novel demonstration devices are more original many, but have following these defectives:＜1〉can not fully demonstrate the contraction and the diastole in ventricle and atrium,＜2〉complex structure, the student is not easy to operate.

The purpose of this utility model is to provide a kind of fish blood circulation demonstration device, and this demonstration device can be demonstrated contraction and the diastole and the whole fish blood circulation process of heart lively, vivid, intuitively, truly, and simple in structure, easy to operate.

For achieving the above object, the solution that the utility model adopts is: this blood circulation demonstration device comprises the simulation ventricle, the simulation atrium, simulation valve and the simulate blood recycle circuit that constitutes by transparent hose, wherein simulate valve and comprise arterial valve, venous valve and atrioventricular valve, its special character is: simulation ventricle and simulation atrium are made of compressible and elastic component diastole, link to each other by transparent hose between them, the simulate blood recycle circuit is from ventricle, successively through arteries, gill capillary, the back arteries, get back to the atrium behind thin blood vessel of chaeta and the vein blood vessel, the simulation valve is made of retaining valve, they are installed in respectively between ventricle and the arteries, between atrium and the vein blood vessel and between ventricle and the atrium.

Small-sized balloon inflation pump can be adopted in above-mentioned simulation ventricle and simulation atrium.

In the above-mentioned demonstration device, on the back side of the lower semisection of the lower semisection of arteries, vein blood vessel, gill capillary and the thin blood vessel of chaeta, scribble blue lacquer, stream venous blood in the expression; On the back side of the upper semisection of the upper semisection of back arteries, gill capillary and the thin blood vessel of chaeta, scribble red lacquer, stream arterial blood in the expression; On the front in ventricle and atrium, scribble blue lacquer, fill venous blood in the expression.

Above-mentioned demonstration device can be installed on the model of fish.

The utility model compared with prior art has following advantage:＜1〉because this demonstration device is to fill red liquid in making by compression simulation ventricle and simulation atrium to flow, thereby it can be truly, very see contraction and diastole and the whole sanguimotor process that ventricle and atrium be demonstrated in ground;＜2〉simple in structure, easy operating, student's experiment of can doing yourself.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the scheme of installation of retaining valve in the utility model.

As shown in Figure 1, the utility model comprises simulation ventricle 1, simulation atrium 2, simulation valve and simulate blood recycle circuit, in the present embodiment, what adopted in simulation ventricle 1 and simulation atrium 2 is small-sized balloon inflation pump, this inflator pump is when compressible on time with subordinate, then resile immediately after decontroling hand, therefore can fully demonstrate the contraction and the diastole of heart, link to each other by transparent hose between Fig. 1 centre chamber 1 and the atrium 2 with this inflator pump; The simulate blood recycle circuit is made of transparent hose, it is from ventricle 1, behind arteries 3, gill capillary 4, back arteries 5, the thin blood vessel 6 of chaeta and vein blood vessel 7, get back to atrium 2 successively, between above-mentioned gill capillary 4 and arteries 3, the back arteries 5, link to each other by three-way pipe between the thin blood vessel 6 of chaeta and vein blood vessel 7, the back arteries 5, fluid seepage when preventing to use scribbles super glue at each interface (except the interface at can red liquid place).The simulation valve comprises arterial valve 8, venous valve 9 and atrioventricular valve 10 among Fig. 1, in the present embodiment, they all adopt retaining valve to constitute, wherein arterial valve 8 is installed between arteries 3 and the ventricle 1, venous valve 9 is installed between vein blood vessel 7 and the atrium 2, atrioventricular valve 10 is installed between ventricle 1 and the atrium 2 (as shown in Figure 2), and above-mentioned three valves can effectively prevent the refluence of red liquid.

In order to make the student understand the blood circulation system of fish better, in the present embodiment, promptly scribbling blue lacquer on student's the one side dorsad on the back side of the lower semisection of arteries 3, vein blood vessel 7 and gill capillary 4 and the thin blood vessel 6 of chaeta, stream venous blood in the expression, on the back side of the upper semisection of back arteries 5, gill capillary 4 and the thin blood vessel 6 of chaeta, promptly scribble red lacquer on student's the one side dorsad, stream arterial blood in the expression, promptly on student's one side, scribbling blue lacquer on the front in ventricle 1 and atrium 2, fill venous blood in the expression.

Simulation ventricle 1 in the utility model and simulation atrium 2 are except that adopting above-mentioned small-sized balloon inflation pump, the elastic component that can adopt other to make also by plastics or rubber, better as the elastic properties of materials that is adopted, shock mount not in it, relatively poor as the elastic properties of materials that is adopted, then need load onto spring within it, so that simulation ventricle 1 and simulation atrium 2 can the elasticity diastoles.

For vivid, lively, true to nature more, the utility model can be fixed on the model 11 of fish.

The utility model is to use like this: take the junction between gill capillary 4 and the back arteries 5 apart (also can select other places for use) earlier, then red liquid is packed in the recycle circuit sebific duct, half-full until ventricle 1 and atrium 2, and discharge gas in the chambers of the heart simultaneously, make the chambers of the heart be in the half easypro state that contracts, connect then and go up gill capillary 4 and back arteries 5, can demonstrate.During demonstration, press down ventricle 1, represent that promptly ventricle 1 shrinks, at this moment red color visible liquid flows to arteries 3 from ventricle 1, gets back to atrium 2 at last along arteries 3, gill capillary 4, back arteries 5, the thin blood vessel 6 of chaeta, vein blood vessel 7, can see atrium 2 diastoles this moment, press down atrium 2 then, promptly represent atrium 2 contractions, visible ventricle 1 diastole this moment, red liquid does not flow in the recycle circuit sebific duct, shows that the blood in atrium 2 has flowed into ventricle 1.After demonstration finishes, the red liquid in the chambers of the heart all be poured out, and the air-dry chambers of the heart, be got rusty to prevent the spring in the chambers of the heart, follow the string, what adopt as the chambers of the heart is above-mentioned small-sized balloon inflation pump, because spring is not equipped with in inside, then can red liquid not poured out.
