Abstract
The invention discloses a preparation method of a simulative human body bone tissue model. The preparation method comprises the following steps of: 1, preparing semi-rigid polyurethane foams from a first ingredient, wherein the semi-rigid polyurethane foams are taken as osteoporotic tissues; and 2, preparing a polyurethane integral skin from a second ingredient, wherein the polyurethane integral skin is taken as an appearance bone tissue; the first ingredient comprises the following components in parts by weight: 100 parts of polyester polyol PS2352, 1.5 parts of a surfactant B 8471, 2.2 parts of PELAT 9540, 0.5 part of POLYCAT 46 (Potassium Acetate), 0.5 part of water, 30.0 parts of foamed HCFC-141b (Hydrochlorofluorocarbons-141b), and 250 parts of isocyanate; and the second ingredient comprises the following components in parts by weight: 100 parts of the polyester polyol PS2352, 1.5 parts of the surfactant B 8471, 2.2 parts of the PELAT 9540, 1.5 parts of the POLYCAT 46, 1.0 part of N,N-dimethyl cyclohexylamine, 0.50 part of pentamethyl diethylene triamine, 0.5 part of water, 40.5 parts of the foamed HFC-245Fa, and 250 parts of the isocyanate. The model prepared with the preparation method has a high simulation degree, the tissue structure and the hand feeling of the model are similar to those of human body bone tissues, and simultaneously, the model has good physical properties, can be used repeatedly, and facilitates teaching simulation.
Description
Technical field
The invention belongs to the manufacturing field of medical educational model, relate in particular to a kind of simulated humanbody osseous tissue Preparation of model method.
Background technology
In medical teaching, dissect in order to teach skeleton, training orthopaedics surgical operation usually needs skeleton specimen, existing skeleton specimen many from live body, not only Financial cost is high, and makes and preserve that all operation is complicated.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of simulated humanbody osseous tissue Preparation of model method, makes that the model emulation degree of preparing is high, has more practicality, is beneficial to teaching.
The present invention is achieved through following technical scheme:
A kind of simulated humanbody osseous tissue Preparation of model method comprises: one, according to batching one preparation polyurethane semihard foam, as the osteoporosis tissue; Two, prepare urethane from skinning according to batching two, as the appearance osseous tissue, said batching one comprises following component; Be by ratio of weight and the number of copies: 100 parts of polyester polyol PS2352,8,471 1.5 parts of surfactant B, 9,540 2.2 parts of PELAT; 46 0.5 parts of POLYCAT; 0.5 part in water, 30.0 parts of foaming HCFC-141b, 250 parts of isocyanic ester; Said batching two comprises following component, is by ratio of weight and the number of copies: 100 parts of polyester polyol PS2352,8,471 1.5 parts of surfactant B; 9,540 2.2 parts of PELAT, 46 1.5 parts of POLYCAT, N; 1.0 parts of N-dimethylcyclohexylamines, 0.50 part of five methyl diethylentriamine, 0.5 part in water; 40.5 parts of foaming HFC-245Fa, 250 parts of isocyanic ester.
Further, the slippery of the pure and mild isocyanic ester of polyester polyols is 26 ± 3 in the above-mentioned batching.
Model according to the method for the invention preparation has high emulation, and weave construction and feel can both be approximate with body bone tissue, have good physicals simultaneously, can use repeatedly, are beneficial to teaching simulation.
