Problems solved by technology

[0005] Find by analysis, the prior art of existing electrolytic oxidation potential disinfection water mainly concentrates on aspects such as the design of electrolysis device and preparation of alkaline drinking water and drinking water disinfection, still can not meet the needs of medical treatment to disinfection and cleaning: 1, there is no special aim at Medical cleaning solution for disinfection and cleaning of wounds and wounds
The existing electrolyzed water technology, its preparation method, technological process, electrolysis conditions, etc. are designed mainly for the use in agriculture, daily life, etc., and cannot be used for cleaning and disinfecting wounds and wounds in medical treatment.
2. Insufficient purification of water treatment
Conventional methods such as multi-stage filtration cannot remove impurities such as ions and organic matter in water, and are easy to clog and difficult to clean
The water for cleaning and disinfecting wounds must meet certain purity requirements. The existence of bacteria, organic matter and impurity ions will affect the service life of the equipment, the purity of the disinfection cleaning solution, the cleaning and disinfection effect, the storage life, and even cause secondary damage to the human body.
3. There is an osmotic pressure difference between ordinary oxidation potential disinfectant water and the wound, and the pain is stronger when disinfecting and cleaning the wound, causing additional pain to the wounded

Embodiment 1

[0044] figure 1 It is a schematic structural diagram of an isotonic disinfection cleaning solution preparation equipment according to Embodiment 1 of the present invention.

[0045] As can be seen from the figure, the preparation equipment for the isotonic disinfection cleaning solution of this embodiment includes: a raw water treatment system, an electrolysis system, and an isotonic adjustment system sequentially connected by pipelines from the direction of water outlet, and the raw water treatment system includes: sequentially connected by pipelines from the direction of water inlet Ultrafilter 1, activated carbon filter 2, microfilter 3 and reverse osmosis unit, ultrafilter 1 is two groups, in order to ensure that the water produced by the ultrafiltration membrane module can meet the requirements of the permeable membrane module, the system can use ultrafiltration The membrane modules are divided into two groups, and the two groups of ultrafilters are connected in parallel....

Embodiment 2

[0055] The difference between this and Example 1 is that the conductivity of the raw water used in this example is 860 μS / cm, the flow rate of II-level reverse osmosis product water is 600 L / h, the concentration of NaCl aqueous solution in the electrolyte adjustment kit is 80 g / L, and the dosage is automatically adjusted The delivery volume of the pump is such that the concentration of the mixed electrolyte is 700mg / L, and the flow rate of the anode and cathode chambers is distributed at a flow ratio of 2:1, and then enters the electrolysis device, that is, the anode chamber inlet flow is 400L / h, and the cathode chamber inlet flow is 400L / h. The water flow rate is 200L / h, the electrolysis voltage is 32V, and the current is 90A. It can obtain a disinfection cleaning solution with a pH value of 2.59, an oxidation-reduction potential (ORP) of 1186mV, and a total oxide content of 70.3mg / L. It is pre-configured in the isotonic liquid adjustment medicine box 120g / L pharmaceutical gra...

Abstract

The invention discloses a method and equipment for preparing an isosmotic disinfection cleaning solution. The method for preparing the isosmotic disinfection cleaning solution comprises the following steps of: performing ultrafiltration, active carbon filtering, micro-filtration and reverse osmosis treatment on raw water to obtain purified water; mixing the purified water with an NaCl aqueous solution to obtain electrolyte, feeding the electrolyte into an anode chamber and a cathode chamber of an electrolysis unit and continually applying direct current to the anode and the cathode of the electrolysis unit to electrolyze, wherein water with the pH value of greater than 7 is produced in the cathode chamber, and a disinfection cleaning solution with the pH value of smaller than 7 is produced in the anode chamber; and mixing the disinfection cleaning solution produced in the anode chamber with the NaCl aqueous solution and filtering with a terminal to obtain the isosmotic disinfection cleaning solution. The preparation method disclosed by the invention is scientific and reasonable, various defects existing in the prior art are overcome, continuous, stable, quick and efficient preparation of the isosmotic disinfection cleaning solution is realized, and the isosmotic disinfection cleaning solution can be applied to cleaning, disinfection and the like of medical instruments and environments such as wounds, wound surfaces, sickrooms, sick beds, clothes, endoscopes, dialysis machines and the like.

Description

technical field [0001] The invention relates to the technology of disinfection and cleaning solution, in particular to a preparation method and equipment of isotonic disinfection and cleaning solution. Background technique [0002] In the medical treatment of public health emergencies, natural disasters and wars, the use of disinfectants and wound cleaning solutions is large, and it is used in a large dose in a short period of time. Most of the disinfectants and cleaning solutions currently used are liquid formulations, which are inconvenient to transport and difficult to supply urgently. In addition, the preparation of water for solid disinfectants is also a problem. Using impure water sources to dissolve and dilute solid disinfectants will greatly reduce the disinfection efficiency. Therefore, there is an urgent need for a high-efficiency, quick-acting, broad-spectrum, non-toxic, non-residue, non-polluting, harmless to personnel, animals, soil, plants, and non-irritating ...
