Problems solved by technology

Therefore, the whole process takes more than half a year, or even ten months, which is a big problem for medical research; meanwhile, because acetone and silica gel are relatively expensive, the cost of plasticizing materials remains high. The plastification material of an adult specimen needs about 20,000 yuan. If the cost of equipment such as vacuum steel tanks is added, the cost will be even greater. This is unbearable for ordinary schools or units. a puzzle in research

Embodiment Construction

[0013] The treated human specimens are dehydrated with alcohol in gradients at 35%, 55%, 75%, 95%, 100%, and then 100%. Each level of dehydration takes 1 to 2 days, and the dehydration time is also acceptable. Depending on the size of the specimen, this is much cheaper than dehydrating with acetone; dissolve not less than 15% foam in chloroform, usually 20% foam in chloroform; place the human specimen in The chloroform solution is soaked in a sealed tank, and the specimen is taken out when the plasticizer is about to be completely solidified; then the soaked specimen is fixed or shaped, and it is naturally cured and air-dried in a well-ventilated environment until There is no smell, and the whole process takes less than a month.

[0014] When soaking, it can also be soaked in a thicker plastic bag that can extract air, the effect is better, and the amount of plasticized materials can also be reduced.

[0015] The chloroform used in this technology is a substance with certain ...

Abstract

A process for preparing the plasticized the specimen of human anatomy includes such steps as gradient dewatering of human specimen in alcohol, dissolving the foam plastic in chloroform, immersing the treated human specimen in the chloroform solution in sealed condition until the plasticizer will be fully coagulated, and drying the human specimen in the air.

Description

technical field [0001] The invention relates to a method for making plasticized specimens of human anatomy. Background technique [0002] Before the present invention, the plasticizing material used for human plastination specimens was silica gel, that is, the human body specimens were dehydrated in a gradient manner with acetone, and the dehydration time would take several months; It takes more than 10 days to infiltrate the plasticized material. After the plasticized material penetrates into the human body specimen, it will be shaped and finally cured. Therefore, the whole process takes more than half a year, or even ten months, which is a big problem for medical research; meanwhile, because acetone and silica gel are relatively expensive, the cost of plasticizing materials remains high. The plastification material of an adult specimen needs about 20,000 yuan. If the cost of equipment such as vacuum steel tanks is added, the cost will be even greater. This is unbearable f...
