Abstract
The invention discloses a medical teaching aid for indicating the shape and color of excrement and a preparation method of the medical teaching aid. The medical teaching aid comprises, by weight, 100000-300000 parts of fine gypsum powder, 6-18 parts of polyvinyl alcohol and 24-72 parts of acrylic amide. The excrement model teaching aid enables students to make a judgment visually according to the shape and color of the excrement, clearly understand the relation between pathological change and change of the shape and color of the excrement, and quickly grasp diagnosis knowledge.
Description
Technical field
The present invention relates to a kind of medical science teaching aid, be specifically related to medical science teaching aid showing stool shape, color and preparation method thereof.
Background technology
Clinical diagnose by inquiring patient, observing, the means such as inspection, obtain state of an illness information, and accordingly identification carried out to patient health state and pathology essence, illness is judged.Tcm theory is summarised as prestige diagnostic method, hears, asks, cuts " four methods of diagnosis ".Observe the excremental shape of patient, look, matter, amount in observation, therefrom noting abnormalities is one of conventional method of the diagnosis state of an illness.In medical teaching in the past, medical students ' learning diagnostic knowledge, with the word picture of teaching material literature record and teacher, can only understand stool shape, color change, infers the pathological change of health abstractively.Lack intuitively, perception cognition.If there is teaching aid demonstration intuitively, just this situation can be changed.
Summary of the invention
The object of the present invention is to provide a kind of medical science teaching aid of show to defecate shape, color, shape, the color of stool can be observed intuitively, allow student with the naked eye can observe directly the form of stool, and rapidly, accurate understanding and grasp dependent diagnostic knowledge.Meanwhile, feeling sick and detesting and rejecting of classmates caused by clinical true excreta is avoided.
Technical solution of the present invention is in order to achieve the above object: a kind of medical science teaching aid showing stool shape, color, makes: meticulous gesso 100000 ~ 300000, polyvinyl alcohol (PVA) 6 ~ 18, acrylamide 24 ~ 72 by the weight portion of following ingredients.
Optimum ratio: meticulous gesso 200000 ~ 230000, polyvinyl alcohol (PVA) 12 ~ 14, acrylamide 48 ~ 55.
Further optimum ratio: meticulous gesso 200000, polyvinyl alcohol (PVA) 12, acrylamide 48.
Show a method for making for the medical science teaching aid of stool shape, color, comprise the steps:
1, prepare gesso, gesso is crossed 200 mesh sieves, landplaster particle≤75 μm;
2, prepare glue, add water, polyvinyl alcohol (PVA), acrylamide in a reservoir, stir, the proportions of 100000: 6: 24 pressed by water, polyvinyl alcohol (PVA), acrylamide;
3, shaping, by prepare glue, gesso in the ratio of 5: 10, pour in container and stir, be modulated into thick gypsum paste; Gypsum paste is loaded in soft plastic bottle, with fashion of extrusion, allows gypsum paste flow out from bottleneck, gypsum paste is contained in disk, by stool shape, at ambient temperature, dry 48 hours, white stool model can be obtained.
4, dye, cause all kinds of colors of stool color change according to the change of common clinical reason, with propylene dyeing, after drying and moulding, the stool model teaching aid of medical teaching can be become.
Advantage of the present invention: this stool model teaching aid can allow student judge according to shape, color intuitively, grasps diagnostic knowledge rapidly.Model of such as normally defecating is yellow, in soft cylindric or strip; Pathology dry feces, dry as sheep dung, black, in graininess; Patients with Jaundice stool model is canescence, potter's clay shape; Dysentery patient model of defecating is purulence color, mucus shape; Gastrorrhagia patient model of defecating is black, as pitch shape; Hemorrhoid patients stool surface is scarlet color, fine strip shape.
