Abstract
The invention relates to a model for demonstrating secondary hydronephrosis of renal calculus. The model can vividly demonstrate a pathological process of the secondary hydronephrosis of the renal calculus for students. The technical scheme includes that the model comprises a human body urinary system simulation model consisting of a kidney model, a ureter model, a bladder model and a urethra model, the kidney model comprises a renal tuberculosis cavitation and a renal pelvis, the ureter model comprises a fibroplasia model and a caseous necrosis focus, one end of a ureter is communicated with the renal pelvis, the other end of the ureter is communicated with a bladder, a prostate model is located around a urethra, and adjusting switches are respectively arranged at the lower end of the renal tuberculosis cavity and the outer side of the ureter. The model is simple in structure and convenient to realize, visually and vividly displays the pathological process of the secondary hydronephrosis of the renal calculus, and can impress students deeply.
Description
Technical field
The present invention relates to a kind of teaching and use the teaching aid teaching aid, renal tuberculosis secondary nephredema demonstrating model.
Background technology
In the pathology teaching, when lecturing renal tuberculosis, the nephrophthisis solubilized is sent out.Because the caseous necrosis thing is discharged from urine in a large number, causes ureter, bladder to be got involved in succession, can make the narrow secondary nephredema of ureteral lumen.The assistant teaching aid that adopts in the instruction is a multimedia and sample substantially, has following shortcoming: multimedia show can not Direct observation, and the student can not operate in person; Sample can not be showed dynamic process substantially, and carries inconvenience.
Summary of the invention
Summary of the invention:
The technical matters that the present invention will solve provides the teaching aid of a kind of demonstrating visual, image, is convenient to understand renal tuberculosis and causes nephrydrotic pathologic process.For solving the problems of the technologies described above; The present invention adopts following technical scheme: said renal tuberculosis secondary nephredema liquid demonstrating model; Comprise the human body urinary system realistic model that kidney model, ureter model, bladder model and urethra model are formed, said kidney model comprises nephrophthisis cavity model, renal papilla caseous necrosis kitchen range and renal plevis model, and said ureter model comprises fibroplasia model and caseous necrosis kitchen range; Ureter model one end and renal plevis model are connected; The other end and bladder model are connected, and the prostate model is positioned at around the urethra model, and renal papilla cheesy necrosis kitchen range lower end and ureter model are respectively arranged with by-pass cock.
The present invention provides a kind of renal tuberculosis secondary nephredema demonstrating model teaching aid, has the following advantages:
(1) demonstrates continuous dynamic process, lifelike image;
(2) be able to understand the image of renal tuberculosis
ureter tuberculosis ?
ureter mucosal damage and fibrosis
? stenosis
hydronephrosis secondary to the occurrence of the development process;
(3) simulated operation is repeatable.

Embodiment:
For the technological means that the present invention is realized, purpose of reaching and effect consistance below in conjunction with concrete demonstration, further specify the present invention.
Renal tuberculosis is many send out voluntarily by primary pulmonary tuberculosis due to; pathology originates in renal papilla, because the caseous necrosis thing is discharged from urine in a large number, causes ureter, bladder to be got involved in succession; mucous membrane of ureter destroys, and proliferation of fibrous tissue can cause ureterostenosis and the secondary nephredema.
Based on above-mentioned principle; Demonstrating model provided by the invention is as shown in Figure 1, and is existing with reference to accompanying drawing 1, explains as follows in conjunction with embodiment: renal tuberculosis secondary nephredema demonstrating model of the present invention; Comprise the human body urinary system realistic model that kidney model 1, ureter model 5, bladder model 7 and urethra model 9 are formed; It is characterized in that said kidney model 1 comprises nephrophthisis cavity model 2, renal papilla caseous necrosis kitchen range 3 and renal plevis model 4, said ureter model 5 comprises fibroplasia model 6 and ureter caseous necrosis 12; Ureter model 5 one ends and renal plevis model 4 are connected, and the other end and bladder model 7 are connected; Prostate model 8 is positioned at around the urethra model 9, and renal papilla caseous necrosis kitchen range 3 lower ends and ureter model 6 are respectively arranged with by-pass cock 11,13.
Such structure can image the structure that demonstrates urinary system, renal papilla caseous necrosis kitchen range 3 lower ends are provided with by-pass cock 11 scalable cheesy necrosis things with the descending speed of urine, the pathologic process of sending out with the demonstration renal tuberculosis of lifelike image.Ureter by-pass cock 13 scalable ureter models 5 be because proliferation of fibrous tissue can make luminal stenosis, narrowly make that urine is descending is obstructed when serious, and cause renal plevis 4 ponding.
The concrete presentation process of exemplary model that obtains according to technique scheme is following:
During use; In caseous necrosis thing 2, liquid 10 (simulation urine) nephrophthisis of packing into cavity 2; Open renal papilla caseous necrosis kitchen range by-pass cock 11 then; Make to be advanced into renal plevis model 4, ureter model 5, bladder model 7 and urethra model 9 under weak yellow liquid 10 (simulation urine) and the caseous necrosis thing and to discharge, the caseous necrosis thing can involve the ureter rose of Sharon 5 and bladder model 7 simultaneously, and can make ureter wall proliferation of fibrous tissue 6; Cause ureter model 5 luminal stenosis, urinary tract is narrow to simulate, obstruction causes nephredema for scalable ureter model by-pass cock 13 at this moment.
More than simulated the pathologic process of renal tuberculosis secondary nephredema demonstration.
Claims (2)
