Problems solved by technology

However, the effectiveness of treating chemical burns with water is limited by two factors
The first is time, washing with water must occur within ten seconds of burns, otherwise, it is still possible to cause varying degrees of damage
And this condition proved to be difficult to meet in many accidents; the second is that a large ...

Embodiment 1

[0018] Embodiment 1 decontamination solution of the present invention is to the buffering action of acid-base

[0019] (1) decontamination solution of the present invention is to the buffering action of strong acid

[0020] Precisely configure 0.5mol / l H 2 SO 4 solution. Add the configured H into two 50ml beakers respectively 2 SO 4 Solution 5ml, then respectively add 0, 5, 10, 15, 20, 30ml of decontamination liquid and pure water that the present invention makes, measure its pH value after fully mixing, and each batch of experiments is repeated 3 times.

[0021] The decontamination solution of the present invention is to H 2 SO 4 The buffering effect of the solution is shown in Table 1. The results show that the decontamination solution prepared by the present invention has a good effect on H 2 SO 4 The solution has obvious buffering effect.

[0022] The decontamination solution that the present invention makes of table 1 is to H 2 SO 4 The buffering effect of the...

Embodiment 2

[0029] Embodiment 2 skin irritation test

[0030] Rabbits: 8, half male and half male, weighing 1.5-2.5Kg.

[0031] Observe that the decontamination solution of the present invention has no irritating effect on the damaged skin and damaged skin of rabbits. The evaluation criteria for erythema and edema were carried out according to the "skin irritation reaction score and skin irritation intensity" in the "Compilation of Preclinical Guidelines for New Drugs".

[0032] The results show that the decontamination solution of the present invention is non-irritating to the skin in Table 3.

[0033] Table 3 Rabbit skin irritation test results

[0034]

Embodiment 3

[0035] Embodiment 3 animal skin decontamination effect experiment

[0036] (1) Preparation of decontamination solution

[0037] The weight ratio of the decontamination solution is: tetraethylenepentaminediacetic acid 7%, glucose 1%, polyethylene glycol 0.3%, glycerol 1.5%, boric acid 0.4%, glutamic acid 0.3%, cysteine ​​1.5% , aspartic acid 0.5%, sodium chloride 1%, water 86.5%. The pH of the decontamination solution was 6.5.

[0038] (2) Decontamination effect test

[0039] The back of the rabbit was depilated before the test, and then the filter paper sheet soaked in concentrated sulfuric acid and sodium hydroxide solution was used to stick it on the exposed skin of the rabbit's back. Fluterine) were used to wash the burned skin at the same speed, and the comparison of the actual wound healing effect of the burned skin is shown in the schematic diagram of the photo. The results show that the decontamination solution of the present invention has a good protective effect o...

Abstract

The invention relates to human body decontamination liquid in the field of industrial safety protection. The human body decontamination liquid can protect human bodies from being burned by chemical substances. The human body decontamination liquid comprises chelating agents, sugar, alcohol, complexing agents, univalent metal salt and water. The human body decontamination liquid which is a composition has the advantages that chemical hazardous articles such as acid, alkali, oxidizing agents, reducing agents, complexing agents and solvents can be converted into products which are harmless to the human bodies and environments, and accordingly secondary injury and pollution can be prevented; the composition has merits and potential in the aspects of chemical hazardous article decontamination potency, safety and the like as compared with products with single corrosion-resistant components on markets; the human body decontamination liquid is suitable for emergency protection and rescue during industrial production, so that burning and erosion on the human bodies due to the chemical substances can be relieved.

Description

technical field [0001] The invention relates to a human body decontamination solution used in the field of industrial safety protection, and is particularly suitable for protecting human body from being burned by chemical substances. Background technique [0002] In modern production and life, people use more and more chemicals. According to statistics, there are more than 35 million chemical species registered in the International Chemicals Agreement, and they are still growing at an extremely fast rate. How to prevent and control the risk of using chemicals and take remedial measures to reduce the damage to people caused by the risk has been a topic that people have been working on for a long time. Among chemical risks, chemical burns are one of the most common and commonly occurring risks. It causes human molecules, cells or skin tissues to be stimulated or corroded by chemicals, and partially or completely destroyed. Chemical burns occur when a person's eyes or skin c...
