Human body plasticization is a technique that replaces waterin human organs and tissues with liquid silicone compounds andtransforms the human body into specimens that can bepermanently preserved. Invented by Gunther von Hagens, anexpert in German anatomy.

Expand edit this paragraph overview
He is a teaching aid for anatomy. . . . . . He was inspired by theworks of Renaissance anthropologists.
Most of hisbodyis inChineseplasticized specimens (it is saidthat he hired 200 workers Chinese) , this technology requiresa lot of labor, but also very time-consuming, a year can onlymake a specimen (his patent expires, this technology byAmerican D. Corelle is changed, only the original 1/10 time) .Plasticizing requires cleaning the body first (just as in ahuman bath) , then soaking it in acetone, removing moisture fromthe tissues and preparing for injecting silicone polymersAfter the whole body was soaked into the body is plasticizedby reducing the pressure inside, the acetone into gasevaporated from polymer in the body, was pressed in finally theskin coated with catalyst, beginning two days of curingBody building costs about $50000.
Biological plasticization is a special technique that keepstissues as alive. It uses a vacuum process of biologicalspecimens were infiltrated with silicone rubber, epoxy resinand other active polymer, the type of polymer, determines theoptical properties of soaked specimen (transparent or opaque)and mechanical properties (soft and tough) . The plasticizingtechnique allows the surface of the specimen to remain in itsoriginal state, and preserves the structure of the cell at themicroscopic level. The plasticized specimens are dry,
tasteless, durable, and can be preserved for long periods oftime and easy to learn.
Edit the four steps of plasticizing technology in this section
(1) fixed
Faure Marin is mainly used for fixed.
(2) dehydration and degreasing
Acetone is used as dehydrating agent, degreasing agent andintermediate solvent in vacuum.
(3) forced infiltration;
Under vacuum conditions, acetone is replaced with silicone,epoxy and other polymeric liquids.
(4) polymerizati on
The polymers were polymerized by gas, light, or heating.Edit the technical category of this section
(1) silicon rubber impregnation technology is mainly used inthe manufacture of teaching specimens. The soft and toughspecimens are the most widely used;
(2) poly emulsion technology is mainly used in the manufactureof wooden products and thick body fracture specimens (>1cm) in
archaeology. The specimens are opaque and hard;
(3) the epoxy resin technique, which is mainly used for makingspecimens of thin bodies and organs, is transparent and ofdifferent tissue colors;
(4) polyester copolymer technology, originally used mainly forthe manufacture of brain specimens, which can distinguish thegray matter from white matter, has now replaced epoxy resintechnology.
Edit the process of the whole process of plasticizationFirst, storage
After a concentration of 20% Faure Marin perfusion, and thenin the vacuum packaging Faure Marin placed at least 4 monthstime, and then can be dissected or transported. Faure Marin' srole here is fixed, bactericidal.
The two is anatomy
The body muscle tissue, such as rotting fat, were eliminated,exposing the nervous system, muscles and bones. It takes anaverage of 15002000 hours to clean up a human specimenThree is dehydration
The dissected bodies were soaked in boxes for dehydration.Before that, the body had been contaminated by Faure Marin, soit was necessary to remove Faure Marin from acetone in a low
temperature acetone solution and replace it with acetone.Four is slicing stereotypes
In frozen conditions, the body canbe cut into 3.5 thick sliceswith a saw. These sections can be used to distinguish betweendamaged and normal organs, such as the difference betweensmoking lung and normal lung, and the difference between fattyliver and normal liver. The body was frozen and sliced intovarious shapes. The staff with a small clip, needle, needle,wood and other utensils to dehydration of the body a little putinto shape. This specimen of human body muscle, dry andastringent, not a little flexibility, a red blood vessels andmuscle tissue is clearly visible.
Five is the vacuum replacement
The human body is 70%. The use of liquid plastic sampletechnology, can make the body tissue fluid through a specialvacuum process by activated plastics such as silicone rubber,epoxy resin or polymer resin replacement out. But theobservation of human cells and human' s original appearance evenunder the microscope are still maintain their last state. Thisthe process includes four steps: fixed. Dehydration. Forcedinfiltration. After hardening. Acetone replacement specimenswere placed in the cabin, 4 months with silicone rubber in thecatalyst and gas fumigation, under negative pressure, theacetone is slowly by organic silicon replacement, eventuallybecome non-toxic, tasteless, can be a long time save thefinished specimen.
Plasticizing technology is a German medical doctor professorHagens invented in 1978, it solved the problem of anatomycircles for hundreds of years, since its birth, derived fromthis technology has many application methods, plasticizingtechnology applies not only to human specimens, also suitablefor animal, plant specimen. Plastination technique is widelyused in anatomy, embryology, biology, pathology, clinicalimaging, biomechanics, forensic science and Museum and otherdisciplines and fields.
Plastination to save the body from the formalin, specimenswithout stimulation, with dry and tasteless, durabilitycharacteristics, fault samples high transparency, finestructure, local structure can be studied in a completelynatural condition. The polymer with good physicochemicalproperties. Silicone rubber specimens can have its unique theanatomical structure of display method can be applied inmedical teaching, scientific research and medical sciencepropaganda. Plastination technique can also be applied in thefield of archaeology, anthropology and biology. To effectivelypreserve archaeological data, anthropological data and rareplants and animals of the original. This is very beneficial forscientific research. At present, in our country Guangzhou,Shanghai, Nanjing, Qingdao, Shenzhen, Tai'an and other placesthere are many biological plastic plant specimens.
