As depicted in figs. 1 and 2, the making of the present embodiment Nephron model is:
(One)Prepare material:The white Drexel bottle of the sharp mouth of 1 band;The white clear Coke bottle that 2 capacity are 2L;2 capacity For 0.5L white clear mineral water bottle;4 rubber tubes, wherein 1 thicker a length of 20cm white rubber tube(Hereinafter referred to as A number pipe), 1 thicker a length of 10cm red rubber tube(Hereinafter referred to as No. two pipes), 1 thicker a length of 30cm red Rubber tube(Hereinafter referred to as No. three pipes), a length of 55cm 1 thinner or so red rubber tube(Hereinafter referred to as No. four pipes);1 A length of 50cm or so red electric wire;1 15cm or so thin wire;3 Y-shaped three-way pipes(First three-way pipe 1, the second threeway The three-way pipe 8 of pipe 7 and the 3rd);3-5 root capillary syrings;1 No. 5 rubber stopper;1 segment glass tube;Multi-use mucilage;NaOH particles;It is dilute HCl;Methyl orange;Cotton etc..
(Two)Preparation method and step:
(a)Make glomerulus:Two white clear mineral water bottles are cut from bottom 10cm or so place, band bottom of bottle is left Part, bore the caliber size of one and the first output end 12 of the first three-way pipe 1 white clear mineral water bottle bottom Identical big hole(Through hole 311), many apertures being evenly arranged are bored in another white clear mineral water bottle bottom(Filter bores 312), then two mineral water bottles with bottom of bottle part are sticky at sheared edge(Filter vat 31 is made), finally from great circle 50cm red electric wire is inserted at hole(Coil 32), glomerulus is made(Filter element 3), NaOH is loaded into filter vat 31 Grain.
(b)Make capsula glomeruli:Two white clear Coke bottles are cut from from bottle neck 1/3rd, left with bottle neck In part, the cavity that the glomerulus completed is fitted into one of Coke bottle so that the big hole of glomerulus is directed at this can The bottle neck of happy bottle, upward, the first output end 12 of the first three-way pipe 1 sequentially passes through the bottle neck of the Coke bottle to the bottle neck of the Coke bottle (Housing inlet port 21)In the big hole of glomerulus insertion filter vat 31 inner chamber, by two Coke bottles with mouth portion from shearing It is bonded together at mouthful, the capsula glomeruli outside glomerulus is made(Housing 2).
(c)Make renal tubule:The bottle neck of another Coke bottle is sealed with No. 5 rubber stoppers(Housing outlets 22), the Coke bottle Bottle neck down, and using insertion No. 5 rubber stoppers in glass tube draw No. one pipe, renal tubule is made(Woven hose 5).
(d)Connect blood vessel:As shown in figure 1, the second output end 13 is managed with No. two respectively by the second three-way pipe 7(Segmental arc 412)Receiving terminal and No. three pipe(Second connecting pipe 42)Receiving terminal connection, by No. two No. Guan Yusi manage(Spiral section 411) Connection, and by No. four pipes with spiral wrap on a pipe, have gap between No. four Guan Yuyi pipes, load 1 in No. four pipes Root 15cm or so thin wire so that the helical form of No. four pipes keeps sizing, then by the defeated of the output end of No. three pipes and No. four pipes Go out end to connect by the 3rd three-way pipe 8.
(e)By 3-5 root capillary syrings(Mozzle 6)A number Guan Yusi pipe is connected.
(f)A little cotton is filled in into pipe lower end inner chamber.
The specific operation process of the present embodiment Nephron model is:
(1)The relatively low methyl orange solution of configuration concentration, now the color of methyl orange solution is in faint yellow, by the first configured Base orange solution is mounted in the white Drexel bottle of the sharp mouth of band, then adds a few dilute HCl of drop, the methyl orange added after dilute HCl toward methyl orange solution Solution becomes red, red liquid simulation blood.
(2)To input 11(Afferent glomerular arteriole)Pour into(1)The red liquid of middle making, a part of red liquid passes through Two output ends 13(Efferent glomerular arteriole)The connecting pipe 42 of segmental arc 412 and second is flowed into, some red liquid passes through the One output end 12 is flowed into filter vat 31, by becoming faint yellow with the red liquid after the NaOH particle reactions in filter vat 31 (Red methyl orange solution after NaOH particle reactions with becoming faint yellow)And uniformly flowed into by filter bores 312 in the inner chamber of housing 2, Weak yellow liquid in the inner chamber of housing 2 flows into woven hose 5 by housing outlets 22 again.Red liquid becomes light by filter vat 31 The filtration of glomerulus of the process simulation of yellow liquid, at the same illustrate glomerulus to blood filtering when, it is red in blood Cell is not filtered across.
(3)When weak yellow liquid in the inner chamber of housing 2 flows into woven hose 5 by housing outlets 22, due to the lower end of woven hose 5 The effect of cotton so that weak yellow liquid flows downward to be hindered by cotton, thus most light yellow liquids in woven hose 5 Body flows into spiral section 411 by multiple mozzles 6 and mixed with the red liquid flowed into from segmental arc 412 in spiral section 411, Mixed eventually through the 3rd three-way pipe 8 with the red liquid in the second connecting pipe 42, from only having that the lower end of woven hose 5 is flowed out Sub-fraction weak yellow liquid, simulates the reabsorption of renal tubule.
The concentration of the methyl orange solution configured in the present embodiment is low so that the color of methyl orange solution is in faint yellow, and to It is optimal that methyl orange solution, which becomes cerise, after a small amount of dilute HCl of methyl orange solution addition;It is put into filter vat 31 appropriate NaOH particles, it is optimal with slight surplus after dilute HCl reactions to make it.
The Nephron model of the present embodiment it is simple in construction, be easy to make, in teaching process, students can take action on one's own The Nephron model is made, the raw material used is made and mainly utilizes the Coke bottle and mineral water bottle discarded in daily life, not only It is with low cost, and defective work can be recycled, there is environmental protection, meanwhile, the Nephron model can lively shape As the filtration and reabsorption of the simulation nephron, abstract knowwhy is intuitively changed, visualized, can build light Loose happy academic environment, can enhance memory, students is quickly grasped the filtration and reabsorption of the nephron again Knowledge, beneficial to improving the quality of teaching.In addition, filtration and reabsorption of the Nephron model in simulation urine is formed When, all can the amount of having change and the change of color, wherein, the change of analog quantity, it is necessary to by means of the relevant knowledge in physics, Analog color changes, it is necessary to by means of the relevant knowledge of soda acid in chemistry, that is to say, that in the making of the model, known with biology Knowledge is served as theme, the subject knowledge such as organic infiltration physics, chemistry, and the knowledge of application has stronger subject convergence, therefore can be complete Improve the quality of science of students, the knowledge integration ability of training student in face.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment.To those of ordinary skill in the art, the gained under the premise of the utility model technical concept is not departed from To modifications and variations also should be regarded as protection domain of the present utility model.
