Description
Technical field
The utility model belongs to medical teaching equipment, particularly demonstrates the teaching aid of acute renal insufficiency.
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 illustrative teaching skill (like the model teaching aid demonstration) in teaching
[1], getting in touch between pathological change of student's indigestion and the clinical manifestation.Someone provides urine to form demonstrator
[2], simulated the physiology course that urine forms, but the cause of disease of acute renal insufficiency, pathophysiological mechanism and corresponding clinical manifestation
[3], fail to relate to like oliguresis, anuria etc.
The utility model content
The purpose of the utility model provides a kind of simulation acute renal insufficiency 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 by cardiac module, afferent glomerular arteriole model, glomerulus blood vessel U type loop model, mesangial region model, crescent model, renal tubular necrosis model, a matter pond, pressurized renal tubule model, hypertrophy of the prostate model.Efferent glomerular arteriole model, capsula glomeruli model, renal tubule model, urine pond are formed, and 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.The mesangial region 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 the glomerular filtration membrane ceasma jointly with capsula glomeruli internal layer aperture.Between implantable capsula glomeruli of crescent model and the U type loop, renal tubular necrosis model ceasma is corresponding with a matter pond, and pressurized renal tubule model places a bottom, matter pond, and the hypertrophy of the prostate model connects with urinary tract terminal, gets into the urine pond at last.
A specific embodiment of the utility model that provides through Figure of description below further describes its structure.

Referring to accompanying drawing; The cardiac module 1 of this device is communicated with afferent glomerular arteriole model 2; Glomerulus blood vessel U type loop model 5 one ends link to each other with afferent glomerular arteriole model 2; The other end and efferent glomerular arteriole model 13 join, and mesangial region model 4 is embedded between the glomerulus blood vessel U type loop 5, and glomerulus blood vessel U type loop model 5 forms filtration membrane ceasma 16 jointly with the capsula glomeruli internal layer.Glomerulus blood vessel U type loop model is placed in capsula glomeruli model 15 inner chambers.Between crescent 17 implantable capsula glomerulis 15 and the blood vessel U type loop 5.Renal tubular necrosis model 9 one ends communicate with capsula glomeruli 15, and the other end and pressurized renal tubule model 10 join, matter pond 18 between its ceasma 19 correspondences.In this device; It is pink (simulate blood color) that cardiac module 1, afferent glomerular arteriole model 2, glomerulus blood vessel U type loop model 5, efferent glomerular arteriole 13 adopt transparent material and outward appearance, and capsula glomeruli model 15, renal tubular necrosis model 9, a matter pond 12, pressurized renal tubule 10, hypertrophy of the prostate model 21 and urine pond 12 are transparent material (simulation urine color when water passes through).Mesangial region model 4 is used for fixing blood vessel U type loop 5.Capsula glomeruli model 15 is a double-decker, is mainly used in fixedly glomerulus blood vessel U type loop model 5.Crescent 17 is the first quarter moon shape, and little ceasma 16 is arranged, and plants between capsula glomeruli 15 and blood vessel U type loop 5.
Embodiment
During use, add clear water at cardiac module 1, turn on afferent glomerular arteriole model switch 3, represent blood flow to get into glomerulus U type blood vessel loop 5, liquid filters from glomerulus blood vessel U type loop filtration membrane ceasma 16, and crude urine forms.Acute renal insufficiency can be divided into following three kinds of situation according to pathogenic factor
[3]: (1) before kidney takes place during the property renal insufficiency, as lose blood greatly, severe dehydration, acute heart failure etc., effective circulating blood volume is reduced, renal blood flow is not enough, glomerular filtration rate(GFR descends and causes oliguresis or anuria etc.The caused by factors effective circulating blood volume descends before simulating kidney this moment, and scalable afferent glomerular arteriole switch 3 causes renal blood flow deficiency, filtration rate to descend, and the production process of demonstration oliguresis or anuria; (2) when kidney property renal insufficiency takes place; Common reason has: 1. the acute glomerulonephritis pathological change is that glomerulus endothelial cell, the obvious hyperplasia of mesangial cell cause U type blood vessel loop pressurized and narrow; Block even; Scalable blood vessel U loop by-pass cock 6 is simulated acute glomerulonephritiss at this moment; Narrow because endothelial cell, proliferation of mesangial cells make glomerulus blood vessel U type loop 5 pressurizeds, cause that renal blood flow reduces, filtration rate descends, and the production process of demonstration acute renal insufficiency oliguresis or anuria.2. the crescentic glomerulonephritis pathological change is that capsula glomeruli parietal layer epithelial hyperplasia formation crescent is oppressed the blood vessel loop; Make capsula glomeruli inaccessible; Glomerular filtration rate(GFR descends and oliguresis anuria even, this moment crescent model 17 is implanted between capsula glomerulis 15 and the U type loop 5, regulates crescent by-pass cock 7 simultaneously; Cause that capsula glomeruli is inaccessible, blood vessel U type loop 5 pressurized filtration membrane ceasmas 16 are narrow, make crude urine form barrier, hypourocrinia or anuria.3. the renal tubular necrosis renal ischaemia can make renal tubular necrosis, and cell detachment blocks renal tubule, and this moment, scalable renal tubule by-pass cock 8, renal tubule is blocked increase the weight of.The matter between kidney because basilar memebrane fracture, urine footpath breach are backflowed and oedema, the pressure compressing renal tubule that raises blocks renal tubule to increase the weight of oliguresis more obvious.This moment is corresponding with a matter pond 18 through renal tubule ceasma 19, make former vesicoureteric reflux arrive between matter pond 18, pressure raise to be oppressed the pressurized renal tubule model 10 under it and is made oliguresis more serious.(3) after kidney takes place during the property renal insufficiency, how block and cause by urinary tract, like hypertrophy of the prostate, ureteral calculi etc.Join hypertrophy of the prostate model 21 and urethra end this moment, regulates urethra by-pass cock 11 simultaneously, urethra is squeezed and forms urinary obstruction, and hypourocrinia is anuria even.
In a word, acute renal insufficiency mainly is common or effect successively through factor before the kidney, behind kidney property and the kidney, causes that renal blood flow is not enough, and renal tubular necrosis causes former vesicoureteric reflux, and renal tubule blocks and causes that filtration rate descends, hypourocrinia anuria even.More than demonstrated its pathophysiological processes.
See that from the above-mentioned teaching plan of the utility model this apparatus structure is simple, easy to operate, visual in image.Make the acute renal insufficiency pathophysiological processes, to dynamically, look like specifically by taking out by static state.Can dynamically understand the incidence and development process of acute renal insufficiency, improve the ability of observation of students problem analysis.
