Problems solved by technology

[0003] At present, the plasticization technology needs to use fresh specimens and special biological plasticizers, and impregnate them in large-scale vacuum tanks. The fresh specimens are obtained from less sources and in small quantities, resulting in time-consuming and labor-intensive production methods and higher costs. The application scenarios of large equipment, such as museums and medical schools, are not easy to promote
Moreover, at present, major medical colleges waste a lot of old specimens that have been fixed for a long time, and the decomposed specimens used in daily teaching are greatly wasted.

Embodiment 1

[0040] The preparation method of the old biological plasticized specimen of the present embodiment is carried out according to the following steps:

[0041] (1) Selection and processing of old specimens:

[0042] Select old specimens, process the old specimens into the required specimen shape, expose the specimen structure, wash the surface dirt and residual formalin with clean water, for solid organs or muscle layers, and thicker skin, it is advisable to remove the capsule and use fine The needle is punched in a hidden place, which is convenient for subsequent processing;

[0043] (2) Bleaching of old specimens:

[0044] Use hydrogen peroxide with a mass concentration of 30% to soak the old specimens for 7 days. The bleaching is based on the obvious whitening of the color. When the hydrogen peroxide no longer produces active oxygen, change the liquid and continue soaking; it is not suitable for deep color specimens to be completely bleached. Add glacial acetic acid to the b...

Abstract

The invention belongs to the technical field of biological plasticization, and particularly relates to a manufacturing method and device of an old biological plasticized specimen. According to the method, the waste old specimens are used, the novel plasticizer and the impregnation technology are adopted, large vacuum equipment is not needed, the preparation cost of the plasticized specimens is greatly reduced, the technological process is simple and convenient, the plasticized specimens can be manufactured by themselves in general medical college laboratories, and the plasticized specimens can be manufactured without professional technicians and professional equipment.

Description

technical field [0001] The invention belongs to the technical field of biological plasticization, and in particular relates to a method and a device for making an old biological plasticization specimen. Background technique [0002] Bioplastination is a special technology that can preserve tissues like a living body. It uses a vacuum process to infiltrate biological specimens with active polymers such as silicone rubber and epoxy resin. The polymers used are The species determines the optical properties (transparent or opaque) and mechanical properties (soft and tough) of the soaked specimen. Plastination technology can keep the surface of the specimen in its original state and preserve the cell structure at the microscope level. The plasticized specimen is dry, odorless, durable, can be stored for a long time, and is easy to learn. [0003] At present, the plasticization technology needs to use fresh specimens and special biological plasticizers, and impregnate them in lar...
