Embodiment 1

[0025] Sodium hydroxide 1g / L, sodium metabisulfite 1g / L, edetate disodium 1g / L, glucose 3g / L were prepared into a solution, then 3g / L thymol and perfume 0.5mL / L were added, and The alcohol concentration will be adjusted to 30%.

[0026] A method of using the above solution for anatomical specimens, as follows:

[0027] 1. Prepare the specimens for anatomy teaching, and then soak the specimens of each system in the upper liquid for about one week to ten days according to the order of teaching. After taking them out, you can get formaldehyde-free and a small amount of fragrance. specimen.

[0028] 2. After removing the skin of the human specimen, use this liquid to soak the human specimen for ten to twenty days to remove the formaldehyde, and then proceed to the fine preparation of the specimen, so that the specimen can be basically free from the smell of formaldehyde. Stimulate the impact to achieve the purpose of protecting the health of technicians.

Abstract

The invention relates to preparation of specimen making solution, in particular to preparation of solution capable of removing formaldehyde from a human system anatomic specimen. The soaking preservation solution for removing the formaldehyde from the human anatomic specimen comprises the following components: 1 to 3g / L of sodium hydroxide, 1 to 3g / L of sodium metabisulfite, 1 to 3g / l of ethylene diamine tetraacetic acid, 3 to 5g / L of glucose, 3 to 5g / L of thymol, 0.5 to 1g / L of perfume and the balance of 30 to 40 percent of alcohol. Through a plurality of experiments, the solution newly prepared at one time can soak 5 to 7 batches of specimens, the specimens cannot mildew for 2 to 3 months after being taken out, and the specimens can also be preserved in the solution for a long time and cannot decay; therefore, a good teaching environment for anatomy without formaldehyde odor can be created, so teachers and students can easily teach and learn the anatomy, which accords with the thought of human-oriented scientific outlook on development.

Description

technical field [0001] The invention relates to preparation of a solution for making specimens, in particular to a preparation of a solution capable of removing formaldehyde in anatomical specimens of human body systems. Background technique [0002] Anatomy is one of the most basic courses taught in medical schools and is a must for any medical major. Anatomy teaching specimens have been fixed and soaked in 4% formaldehyde for many years. Formaldehyde is a chemical substance that is volatile and has many hazards to the human body. During the learning and teaching of anatomy, the stimulation of formaldehyde Taste and toxic effect make numerous anatomy teachers and students suffer from it. For many years, people have not found a harmless chemical substance that can replace formaldehyde. Therefore, people try to reduce the harm of formaldehyde by various methods. For example, the method of making plasticized specimens can not only permanently preserve anatomical specimens, ...
