The teaching aid mainly comprises a heart model, an afferent glomerular arteriole model, a glomerular capillary u-shaped loop model, a mesangial region saccus model, an efferent glomerular arteriole model, a renal capsule model, a renal tubule model, a urine pool and a blood pool, thereby forming a model system for demonstrating the pathological clinical correlation of acute glomerulonephritis. The device is simple in structure and convenient to operate, and has high visuality and understandability in the teaching process. Besides, the device facilitates students to foster the observation and problem analysis capabilities.
Description
Technical field
The invention belongs to medical teaching equipment, particularly demonstrate the teaching aid of acute glomerulonephritis pathological change.
Background technology
In theory of medicine teaching, medical knowledge is complicated often abstract, depends merely on to tell about to be difficult to let the student understand easily, mainly adopts multimedia teaching in recent years and has ignored the effect of demonstration mode teaching skill (like the model teaching aid demonstration) in teaching
[2]Main through observing pathological section in experimental teaching, understand pathological characteristic under the glomerulonephritis mirror, getting in touch between pathological change of student's indigestion and the clinical manifestation.Someone provides urine to form demonstrator
[1], simulated the physiology course that urine forms, but glomerulonephritis pathological characteristic and corresponding clinical manifestation fail to relate to like oliguresis, albuminuria, blood urine.
Summary of the invention
The purpose of this invention is to provide a kind of simulation acute glomerulonephritis pathological change demonstrating model.Simple in structure, easy to operate, the teaching visual and understandable, make abstract knowledge become vivid, and can demonstrate the incidence and development process of disease.
Realize that this practical new technique scheme is: mainly be made up of cardiac module, afferent glomerular arteriole model, glomerulus U type blood vessel loop model, mesangial region air bag model, efferent glomerular arteriole model, capsula glomeruli model, renal tubule model, urine pond and blood pool, cardiac module is communicated with the afferent glomerular arteriole model.Glomerulus blood vessel U model, an end links to each other with the afferent glomerular arteriole model, and the other end and efferent glomerular arteriole model join.Mesangial region air bag model is embedded in the middle of the glomerulus blood vessel U type loop, and glomerulus blood vessel U type loop model is placed in the capsula glomeruli mould impression, and glomerulus blood vessel U-shaped loop model pipe is provided with aperture, forms glomerular filtration membrane jointly with capsula glomeruli internal layer aperture.The renal tubule model is connected with the capsula glomeruli model, and the other end gets into the urine pond, and the efferent glomerular arteriole model gets into blood pool.

Embodiment
A specific embodiment of the present invention that provides through Figure of description below further describes its structure.
Referring to accompanying drawing 1; The cardiac module 1 of this device is communicated with afferent glomerular arteriole model 2; Glomerulus blood vessel U type loop model 3 one ends link to each other with afferent glomerular arteriole model 2, and the other end and efferent glomerular arteriole model 7 join, and mesangial region air bag model 5 is embedded between the glomerulus blood vessel U type loop 3; Glomerulus blood vessel U type loop model 3 is placed in capsula glomeruli model 8 inner chambers, and glomerulus blood vessel U-shaped loop model 3 is provided with aperture 6.Renal tubule model 9 is connected with capsula glomeruli model 8, and the other end gets into urine pond 11.The efferent glomerular arteriole model 7 last blood pool 12 that get into.In this device; Cardiac module 1, afferent glomerular arteriole model 2, glomerulus blood vessel U type loop model 3; Efferent glomerular arteriole model 7; It is pink (simulate blood color) that blood pool 12 adopts transparent material and outward appearance, and capsula glomeruli model 8 renal tubule models 9 and urine pond 11 are transparent material (simulation urine color when water passes through).Mesangial region air bag model 5 balloon surface patterns are that (inflation increases simulation endothelial cell, proliferation of mesangial cells for endothelial cell, mesangial cell and matrix synoptic diagram.Capsula glomeruli model 8 is a double-decker, and profile is the flask shape, and internal layer has aperture 4, is mainly used in fixedly glomerulus blood vessel U type loop model 3 and filtration is arranged.
During use, add clear water at cardiac module 1, turn on afferent glomerular arteriole model switch 13, represent blood flow to flow into glomerulus U type blood vessel loop 3, liquid filters from glomerulus blood vessel U type loop aperture 6, leaches through capsula glomeruli model 8 internal layer apertures 4 then, and crude urine forms.Simultaneously, partially liq gets into blood pool 12 through efferent glomerular arteriole 7 in the glomerulus blood vessel U type loop 3.When acute diffuse glomerulonephritis takes place when; Endothelial cell, proliferation of mesangial cells; This moment mesangial region model air bag 5 inflation (simulation endothelial cell, mesangial cell hyperplasia hypertrophy) is made glomerulus blood vessel U type loop 3 pressurizeds and narrow, cause that clear water expands capsula glomeruli model internal layer apertures 4 from glomerulus blood vessel U type loop aperture 6 and leaches minimizings (the simulation glomerular filtration rate(GFR reduces) and formation oliguresis anuria even.Then red blood cell model 15, protein model 16 are added cardiac module 1, leach from glomerulus blood vessel U type loop aperture 6 and capsula glomeruli internal layer aperture 4 along with liquid is descending, simulation acute glomerulonephritis albuminuria, blood urine form.
See that from the above-mentioned teaching plan of the present invention this apparatus structure is simple, easy to operate, visual in image.Make acute glomerulonephritis pathological change, clinical pathology contact, to dynamically, look like specifically by taking out by static state.Can dynamically understand the incidence and development process of acute glomerulonephritis, improve the ability of observation of students problem analysis.
