Description
The present invention relates to a kind of packaging method for making human-body specimen, specifically anticorrosion fixing human body specimen envelope is embedded in the transparent matrix that condensable forms, sample is hedged off from the outer world, thereby reaches the purpose of long preservation human body specimen.The envelope that it is widely used in various biologies and herbarium is buried and the making of handicraft, and teaching and medical research are all had very important use value.
Current store method to the soft sample of human body is also very backward, both uneconomical, and also science not at home and abroad also all is to adopt traditional moist preservation method, i.e. impregnating fluid infusion method.Soft sample is put into vial or lucite container, and the preparation formalin soaks, and not only places occupations of land side, and the easy polymerization of formalin and precipitating, and needs constantly replacing liquid, has the formaldehyde pernicious gas unavoidably to spill the murder by poisoning human body.China for a long time just the someone want to improve the store method of the soft sample of human body, but all do not have successfully.Enter the eighties, the anatomy expert of indivedual countries is arranged in West Europe, once buried human body specimen with the plastics envelope, and obtained progress, but because technology is simple, the sample profile that envelope is buried is very not attractive in appearance, the sample shrinkage is obvious, poor transparency, and actual use value is little.
Purpose of the present invention is exactly that a kind of new method that adopts the resin envelope to bury human body specimen is provided in order to overcome weak point of the prior art, it can make the sample holding time long, transparency good, teaching, view and admire more directly perceived, higher to the diagnosis of CT and operation, clinical medicine, medical research using value especially.
Purpose of the present invention can reach by following measure:
One, the preparation of sample: want the conscientious preservative treatment of carrying out with sealing the sample that buries, shave then except that hair, pubes, whole body and carry out preserved skin, again with washing powder, refer to that brush scrubs repeatedly, clear water washes down, airing, stamps markings by the desire section.
Two, the freezing and saw blade of sample: cadaver sample is freezing in-30~40 ℃ environment, freeze " thoroughly " after, be firmly fixed on the workbench freezing good corpse, saw down piecewise by the fixed signal line, after both sides of plane part is smooth, number consecutively.
Three, the flushing of sample and pruning: after sample is sawn into sheet, cross-section specimen is soaked in the square plate of filling running water piecewise, naturally thaw, with hairbrush Dissolve things inside in the enteric cavity and intravascular coagulation piece are cleared up, scrub clean, and then be placed on this face with the bottom surface of another square plate and overturn, in the same way another side is also scrubbed clean.Repeated multiple times like this, till the clear thoroughly no-sundries of water, the water floating method is all wiped out the fine hair shape floating thing on sample two sides.
Four, sample dehydration: because resin is very little with the mutual solubility of water, so and mist-like bleary can take place after water contacted, do not see after sample is imbedded, when the envelope of wet sample is buried, should note the dehydration of sample, and method after dewatering and time to be noted grasp; Its method is as follows:
(1) dehydration is that sample is put into 45~55% alcohol for the first time, and adds 8~15% glacial acetic acid, and sample is 40~50 hours resting periods in alcohol.
(2) dehydration for the second time be with sample from last liquid, takes out afterwards blot with blotting paper after, be put into again in 55~65% alcohol, ice acetic acid 8~15% again, park after 40~50 hours and take out sample.
(3) dehydration is after sample is taken out from last liquid for the third time, after blotting with blotting paper, sample is put into 65~75% alcohol again, adds glacial acetic acid 8~15% again, parks 40~50 hours.
(4) the 4th dehydrations are after sample is taken out from 65~75% alcohol, after blotting with blotting paper, sample are put into 80%~90%~100%~100% alcohol again, cross twice in 100% alcohol.
(5) treat above dehydration several times after, after sample taken out from 100% alcohol, airing, with blotting paper with the alcohol on surface blot clean after, shaping, prune and labelled (or explanation) after stand-by.
Five, the making of mould:
Mould design, to make according to size and form, the thickness of sample, the material of mould can adopt galvanized iron sheet, glass and steel plate to make, then mould is placed on the glass plate, post with adhesive plaster or paper all around, prevent that resin from leaking outside, after drying, with brush one deck release agent in the mould, prevent demoulding difficulty.
Six, envelope is buried:
According to the size of mould, determine the resin aequum.
(1) an amount of resin is poured in the beaker, after stirring with glass bar, added that 0.5~2% initator is proceeded to stir, and then add promoter 0.5~6% and stir.
(2) mixed resin is poured in the mould felt secure, treat that the end puts into sample after condensing, pour second layer resin again into, generally divide 3~5 layers of perfusion to be advisable.
Room temperature must remain on 20~40 ℃ when (3) envelope was buried.
Envelope is buried used primary raw material-resin, is a kind of unsaturated polyester resin.This unsaturated polyester resin can be done promoter gel and curing under room temperature with the methyl ethyl ketone peroxide cobalt.
Seven, the demoulding and polishing:
After polymerization is finished, take out polymeric block, the envelope of taking out is buried piece polish, till polishing flat according to the form of design.The envelope that to tie is buried piece with waterproof abrasive paper water mill repeatedly from coarse to fine then, is ground to till the no line always.
Eight, polishing:
To polish with the polishing wheel that calico is made behind the water mill, will use antiscuffing paste on the cloth wheel, polish repeatedly, throwing as the natural water spar bright till.
Nine, dress box:
According to the size and form of sample, thickness designs the making of brocade box.After box makes, sample is put into box get final product.
The present invention has following advantage compared to existing technology:
1, this method has been exempted the burden of using specimen bottle and preserving liquid in the wet preservation method, and can prevent the murder by poisoning of formaldehyde pernicious gas to human body.
2, can condense in human body specimen in the residuite, sample is hedged off from the outer world, thereby reach the purpose of long preservation.
3, the sample that adopts this method to make, transparency is strong, and good seal performance is easy to use, and teaching and scientific research are all had very significant values.
