Abstract
The invention discloses a method for preparing a simulated human body rectum model, which comprises the following steps of: firstly, pouring a prepared mixture in a mold which is coated by a demolding agent; then, putting the mold in a baking oven for baking, carrying out rotational molding, cooling after being taken out, and demolding; and finally, trimming and coloring the model. The mixture comprises the following ingredients in parts by weight: 100 parts of polyvinyl chloride (PVC) resin, 5 PHR of acrylate copolymer, 4 PHR of non-toxic organic stabilizer, 3 PHR of chlorinated polyethylene, 0.3 PHR of paraffin organic stabilizer, 1.5 PHR of methyl methacrylate-butadiene-styrene copolymer, 1.5 PHR of butyl stearate, 50 PHR of dioctyl phthalate, right amount of PVC or ethylene-vinyl acetate (EVA) copolymer, 5 PHR of epoxidized soybean oil and 20 PHR of nitrile rubber. The model prepared through the method has the advantages that: the model has high degree of simulation, and the texture and the hand feeling are approximate to those of the rectum of a human body; and meanwhile, the model has excellent physical properties and is applicable to the simulated training of digital rectal examination by teachers and students of medical colleges.
Description
Technical field
The invention belongs to the manufacture field of medical educational model, relate in particular to a kind of preparation method of simulated humanbody rectum model.
Background technology
Digital rectal examination is exactly that the doctor puts in patient's anus with a finger, is a kind of simple and easy to do very important method of clinical analysis that checks disease.When clinic and practice, the medic can not pay attention to the class with classroom by light, needs the actual examination per rectum training of starting to carry out, and knowwhy could be attached in practice and go.Yet, owing to not doing one's exercises on live body, therefore need the human body rectum model of a kind of emulation of exploitation preparation, highly the simulated humanbody rectum, have good physicals simultaneously, the energy Reusability is applicable to teaching and practice.
Summary of the invention
The object of the invention is to propose a kind of preparation method of simulated humanbody rectum model, make the model emulation degree of preparing high, have more practicality, be beneficial to teaching.
The present invention is achieved by the following technical programs:
A kind of preparation method of simulated humanbody rectum model comprises the following steps:
Step 1: the batching configured is poured in the mould that scribbles releasing agent;
Step 2: mould is put into to baking oven and toast, rotation molding, cooling, the demoulding after taking out;
Step 3: model is modified and painted processing, obtained checking assembling after finished product;
Above-mentioned batching comprises following component, is by ratio of weight and the number of copies: 100 parts of polyvinyl chloride (PVC) RESINS; Acrylate copolymer 5PHR, non-toxic organic thing stablizer 4PHR, chlorinatedpolyethylene 3PHR, paraffin organism stablizer 0.3PHR, MBS 1.5PHR, butyl stearate 1.5PHR, dioctyl phthalate (DOP) 50PHR, epoxy soybean oil 5PHR, paracril 20PHR.
Further, also comprise appropriate polyvinyl chloride or ethylene-vinyl acetate copolymer (EVA) in the middle of above-mentioned batching.
Further, the suspension level of above-mentioned polyvinyl chloride (PVC) RESINS is 6 grades, vinyl chloride monomer (VCM) content<1PPM.
Again further, the condition of above-mentioned rotation molding is: 240 ℃ of temperature, time 15-25 minute.
The model prepared according to the method for the invention has high emulation, and weave construction and feel are all approximate with the human body rectum, have good physicals simultaneously, and the energy Reusability, be applicable to the teachers and students of medical college simulated training digital rectal examination, is beneficial to teaching and practice.
Embodiment
Below by specific embodiment, the present invention is described in further detail.
(1) allocation sheet
(2) prepare simulated humanbody rectum model
Comprise following step:
1. the batching that will configure according to the ratio of weight and number of allocation sheet in () is poured in the mould that scribbles releasing agent;
2. mould is put into to baking oven and toast, at 240 ℃ of temperature, rotation molding 15-25 minute, cooling, the demoulding after taking out;
3. model is modified and painted processing, obtained checking assembling after finished product.
The model of preparation has high emulation according to the method described above, and handle effect approaches live body, has good physicals simultaneously, and the energy Reusability, be applicable to the teachers and students of medical college simulated training digital rectal examination, is beneficial to teaching and practice.
Claims (1)
