The teaching aid mainly comprises a heart model, an afferent glomerular arteriole model, a U-shaped glomerular vascular loop model, a mesangial region balloon model, an efferent glomerular arteriole model, a renal capsule model, a renal tubule model, a urine pool and a blood pool, which form a model system clinically relevant to the pathological change of the acute glomerulonephritis. The model is simple in structure, convenient to operate, visual and intelligible in teaching, and conductive to the training of the problem observing and analyzing capability of a student.
Description
Technical field
The utility model belongs to medical teaching equipment, particularly demonstrates the teaching aid of acute glomerulonephritis pathological change.
Background technology
In theory of medicine teaching, medical knowledge is complicated abstract often, depends merely on to tell about to be difficult to allow the student easily understand, and mainly adopts multimedia teaching in recent years and has ignored the effect of demonstration mode teaching skill (as the model teaching aid demonstration) in teaching
[2]Main by observing pathological section in experimental teaching, understand pathological characteristic under the glomerulonephritis mirror, contacting between the pathological change of student's indigestion and clinical manifestation.Someone provides urine producing demonstrator
[1], simulated the physiology course that urine forms, but glomerulonephritis pathological characteristic and corresponding clinical manifestation fail to relate to as oliguresis, albuminuria, blood urine.
The utility model content
The purpose of this utility model is to provide a kind of demonstration model for simulating pathological change of acute glomerulonephritis.Simple in structure, easy to operate, the teaching visual and understandable, make abstract knowledge become vivid, and can demonstrate the carcinogenesis of human of disease.
Realize that this practical new technique scheme is: mainly be comprised of cardiac module, afferent glomerular arteriole model, the U-shaped blood vessel loop of glomerulus 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 is connected 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 U-shaped loop of glomerulus blood vessel, and the U-shaped loop model of glomerulus blood vessel is placed in the capsula glomeruli mould impression, and glomerulus blood vessel U-shaped loop model pipe is provided with aperture, jointly forms glomerular filtration membrane with capsula glomeruli internal layer aperture.The renal tubule model is connected with the capsula glomeruli model, and the other end enters the urine pond, and the efferent glomerular arteriole model enters blood pool.

Embodiment
The cardiac module 1 of this device is communicated with afferent glomerular arteriole model 2, U-shaped loop model 3 one ends of glomerulus blood vessel are connected with afferent glomerular arteriole model 2, the other end and efferent glomerular arteriole model 7 join, mesangial region air bag model 5 is embedded between the U-shaped loop 3 of glomerulus blood vessel, the U-shaped loop model 3 of glomerulus blood vessel 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 enters urine pond 11.Efferent glomerular arteriole model 7 enters blood pool 12 at last.In this device, cardiac module 1, afferent glomerular arteriole model 2, the U-shaped loop model 3 of glomerulus blood vessel, efferent glomerular arteriole model 7, it be pink (simulate blood color) that blood pool 12 adopts transparent materials and outward appearance, and capsula glomeruli model 8 renal tubule models 9 and urine pond 11 are transparent material (water by time simulate urine color).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 schematic diagram.Capsula glomeruli model 8 is double-decker, and profile is the flask shape, and internal layer has aperture 4, is mainly used in fixedly the U-shaped loop model 3 of glomerulus blood vessel and filtration is arranged.
During use, add clear water at cardiac module 1, turn on afferent glomerular arteriole model switch 13, represent that blood flow flows into the U-shaped blood vessel loop 3 of glomerulus, liquid filters from the U-shaped loop aperture 6 of glomerulus blood vessel, then leaches by capsula glomeruli model 8 internal layer apertures 4, and crude urine forms.When acute diffuse glomerulonephritis occurs when, endothelial cell, proliferation of mesangial cells, this moment mesangial region model air bag 5 inflation (simulation endothelial cell, mesangial cell increase hypertrophy) is made U-shaped loop 3 pressurizeds of glomerulus blood vessel and narrow, cause that clear water expands that capsula glomeruli model internal layer apertures 4 leach minimizings (reduction of analogue kidney glomerular filtration rate) and formation oliguresis anuria even from the U-shaped loop aperture 6 of glomerulus blood vessel.Then red blood cell model 15, protein model 16 are added cardiac module 1, leach and form blood urine, albuminuria from the U-shaped loop aperture 6 of glomerulus blood vessel and capsula glomeruli internal layer aperture 4 along with liquid is descending.
From the above-mentioned teaching plan of the utility model, this apparatus structure is simple, and is easy to operate, visual in image.Make acute glomerulonephritis pathological change, Clinicopathologic Correlation,, looked like specifically by taking out to dynamically by static state.Can dynamically understand the carcinogenesis of human of acute glomerulonephritis, improve the ability of observation of students problem analysis.
