Embodiment 1

[0031] In this embodiment, the method for making a biological plastinated specimen that opens from the back and shows the positional relationship of the viscera includes the following steps:

[0032] 1) Selection of materials: select human specimens with intact bones, no fractures, and no lesions.

[0033] 2) Antiseptic treatment, using 20% ​​formalin to perfuse the human specimen, the specific perfusion method is: through the large blood vessels, including the femoral artery, carotid artery, etc., perfuse the formalin into various parts of the human specimen, After the perfusion is completed, the human body specimen is soaked in formalin with a volume concentration of 10% for 5 months to obtain an embalmed human body specimen.

[0034] 3) Dissection, remove the skin, superficial fascia, and deep fascia from the antiseptic treated human specimens, retain the superficial muscles, blood vessels and nerves, cut the ribs at the scapular line of the back, and separate the sacrum an...

Embodiment 2

[0043] In this embodiment, the method for making a biological plastinated specimen that opens from the back and shows the positional relationship of the viscera includes the following steps:

[0044] 1) Selection of materials: select human specimens with intact bones, no fractures, and no lesions.

[0045] 2) Anti-corrosion treatment, using 30% formalin to perfuse the human specimen, the specific perfusion method is: through the large blood vessels, including the femoral artery, carotid artery, etc., perfuse the formalin into various parts of the human specimen, After the perfusion is completed, the human body specimen is soaked in formalin with a volume concentration of 15% for 6 months to obtain an embalmed human body specimen.

[0046] 3) Dissection, remove the skin, superficial fascia, and deep fascia from the antiseptic treated human specimens, retain the superficial muscles, blood vessels and nerves, cut the ribs at the scapular line of the back, and separate the sacrum ...

Embodiment 3

[0055] In this embodiment, the method for making a biological plastinated specimen that opens from the back and shows the positional relationship of the viscera includes the following steps:

[0056] 1) Selection of materials: select human specimens with intact bones, no fractures, and no lesions.

[0057] 2) Anti-corrosion treatment, using 25% formalin to perfuse the human specimen, the specific perfusion method is: through the large blood vessels, including the femoral artery, carotid artery, etc., perfuse the formalin into various parts of the human specimen, After the perfusion is completed, the human body specimen is soaked in formalin with a volume concentration of 12% for 5 months to obtain an antiseptic treated human body specimen.

[0058] 3) Dissection, remove the skin, superficial fascia, and deep fascia from the antiseptic treated human specimens, retain the superficial muscles, blood vessels and nerves, cut the ribs at the scapular line of the back, and separate t...

Abstract

The invention relates to a biological plasticized specimen capable of being opened from back to display the visceral positional relationship, and a preparation method thereof, and belongs to the technical field of biological plasticization. The preparation method comprises the following steps: 1, breaking ribs of a preservative-treated human body specimen from the back to expose visceral organs from the back, separating the sacrum and the hip bone at the sacroiliac joint in a manner of complete separation at one side and ligament reservation at the other side, bleaching the human body specimen, soaking the dissected human body specimen in an acetone solution for 60-80 d, putting the dehydrated and degreased human body specimen in a mixed solution of silica gel and a silica gel catalyst ina vacuum pressure cabin, standing for 50-60 d, adjusting the pressure of the vacuum pressure bin from 0.1-0.3 kPa to 0.9-1.2 kPa during standing, shaping and repairing the impregnated human body specimen, putting the human body specimen in a curing box, and curing the human body specimen by using organic peroxide and aliphatic nitrogen compound steam to obtain the biological plasticized specimen.The biological plasticized specimen displays the shape and position relation of visceral organs from the back, so later specimen observation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of bioplastination, and in particular relates to a bioplastination specimen which is opened from the back to display the positional relationship of viscera and a preparation method thereof. Background technique [0002] The plasticized specimen technology has been applied to the field of biological anatomy specimens for nearly 20 years. The biologically plasticized specimens produced by the plasticized technology have the advantages of non-toxic, odorless, long-term storage, convenient use, and long-term storage in the air. [0003] At present, the commonly used biological plastination specimens for teaching and learning in schools include opening the chest and abdominal wall from the front to display visceral plastination specimens, and opening the chest and abdominal wall from the front to display visceral plastination specimens can only show the positional relationship of the internal organs in the front o...
