Problems solved by technology

However, ε-polylysine is prone to cross-linking reaction with glutaraldehyde, which reduces the antiseptic and bactericidal effect of the preservation, thereby reducing the preservation effect of human specimens; this preservation solution cannot be used for obese and slightly corrupted corpses. Protect
[0007] To sum up, the body is prone to flatulence after use of the existing preservation solution, and the internal organs are prone to blackening, and the preservation time of the body is not long, etc.
In addition, there is currently no special preservation solution and preservation method for obese and slightly corrupted corpses, and the antiseptic preservation solution we have studied before also has the problem of short preservation period

Embodiment 1

[0037] A method for preserving an anatomical specimen, comprising the following steps:

[0038] Step 1. The specimen is flushed by injecting a pretreatment solution through the artery; the pretreatment solution consists of the following components in mass percentage: 45% ethanol, 6% aluminum sulfate, 4% potassium dichromate, and the balance is water.

[0039] Step 2. Perfuse the gastrointestinal tract through a gastric tube and soak in a preservation solution 2 to 3 times its volume for 10 hours, in order to prevent the spoilage bacteria in the digestive tract from damaging the gastrointestinal tract;

[0040] Step 3. Directly pressurize and perfuse the preservation solution into the specimen through the heart cavity, so that the preservation solution can fully penetrate into various tissues and organs of the whole body through repeated circulation through the vascular system to achieve a reliable antiseptic effect; then accommodate the specimen and preserve it. The liquid con...

Embodiment 2

[0047] A method for preserving an anatomical specimen, comprising the following steps:

[0048] Step 1. The specimen is flushed by injecting a pretreatment solution through the artery; the pretreatment solution consists of the following components in mass percentage: 40% ethanol, 8% aluminum sulfate, 3% potassium dichromate, and the balance is water.

[0049] Step 2. Perfuse the gastrointestinal tract through a gastric tube and soak in a preservation solution 2 to 3 times its volume for 8 hours, in order to prevent the spoilage bacteria in the digestive tract from damaging the gastrointestinal tract;

[0050] Step 3. Directly pressurize and perfuse the preservation solution into the specimen through the heart cavity, so that the preservation solution can fully penetrate into various tissues and organs of the whole body through repeated circulation through the vascular system to achieve a reliable antiseptic effect; then accommodate the specimen and preserve it. The liquid cont...

Embodiment 3

[0057] A method for preserving an anatomical specimen, comprising the following steps:

[0058] Step 1. The specimen is flushed by injecting a pretreatment solution through the artery; the pretreatment solution consists of the following components in mass percent: 50% ethanol, 5% aluminum sulfate, 5% potassium dichromate, and the balance is water.

[0059] Step 2. Perfuse the gastrointestinal tract through a gastric tube and soak in a preservation solution 2 to 3 times its volume for 12 hours, in order to prevent the spoilage bacteria in the digestive tract from damaging the gastrointestinal tract;

[0060] Step 3. Directly pressurize and perfuse the preservation solution into the specimen through the heart cavity, so that the preservation solution can fully penetrate into various tissues and organs of the whole body through repeated circulation through the vascular system to achieve a reliable antiseptic effect; then accommodate the specimen and preserve it.

Abstract

The invention discloses a method for preserving an anatomy specimen. The method comprises the following steps of injecting a pretreatment liquid into the specimen via an artery to flush; flushing andcleaning the pretreatment liquid by clean water, filling into a gastrointestinal tract via a gastric tube, and soaking into a preserving liquid for 8 to 12h, wherein the volume of the preserving liquid is equal to 2 to 3 times of the volume of the specimen; directly pressurizing and filling the preserving liquid into the specimen via a heart intercavity, and enabling the preserving liquid to repeatedly circulate via a vascular system and fully permeate into each tissue organ of the whole body; then, sealing a container which is used for containing the specimen and the preserving liquid, and placing. The method has the advantage that the thrombus in the fat and slightly rotted corpse can be well removed. The preserving liquid for the specimen has the advantages that the problems of wrinkling, expansion, mildewing and the like of the specimen can be solved by the preserving liquid, the preserving is convenient, the irritative odor is avoided, the mildew-proof denaturation is strong, theoriginal shape, texture and color of the specimen can be maintained, and the elasticity is better; the bacteria-inhibiting rate is high.

Description

technical field [0001] The invention belongs to the field of medical anatomy teaching, and in particular relates to a method for preserving anatomical specimens. Background technique [0002] Human anatomy is a highly intuitive morphological science, and its experimental teaching activities are inseparable from cadaver specimens. In anatomy courses, teachers mainly use specimens to teach and explain, and students learn by watching specimens. The human specimens used are free bulk specimens, which are mainly preserved with preservation solution. [0003] Existing preservation solution is mainly formalin preservation solution, and formalin solution injection in the blood vessel of human body can prevent the corruption of corpse. Formalin specimen preservation solution has a good fixation effect, which is due to the large amount of formaldehyde combined with the functional groups of the specimen protein, and after long-term storage, it further polymerizes to form paraformaldeh...
