Background art:

For diseases caused by hypoimmunity such as psoriasis, hormone (dexamethasone prednisone dermatitis Pingfutong, etc.) is used, although temporarily effective, to destroy the immune function. The most important treatment for psoriasis is to use drugs, and hormone and immunosuppressant drugs are not used for treatment, and the drugs inhibit the release of vivotoxin, but after the drugs are stopped, most of the drugs relapse or even aggravate, and have great side effects on the body. Psoriasis is a chronic disease and affects the life of patients greatly because the psoriasis affects a wide range of people. Itching, scaling and visible plaques are major problems that afflict patients. Current treatments, while effective, are still unsatisfactory because of the lack of long-term radical treatment. The development of specific, safe, effective long-term treatments remains a challenge.

The common skin disinfectant ethanol can be used for quickly sterilizing the skin, but has no lasting (residual) activity, and the ethanol has a synergistic antibacterial effect when being matched with other chemical antibacterial agents, such as ethylene oxide, and has residual pollution.

Iodine is a skin disinfectant widely applied in clinic, iodine molecules can quickly permeate cell walls, and protein synthesis is difficult and cell membranes are changed by forming amino acid and unsaturated fatty acid, so that secondary pollution exists.

chlorhexidine has a slower immediate antibacterial activity than ethanol. It has good gram-positive bacteria resistance, weak gram-negative bacteria and fungi resistance, small effect on mycobacteria and no effect on spores. In vitro tests have shown efficacy against viruses with membranes such as herpes virus, HIV, cytomegalovirus, influenza virus and RSV, but clearly less effective against viruses without membranes such as rotavirus, enterovirus and adenovirus.

the antibacterial agent of quaternary ammonium salts such as benzalkonium bromide and the like has strong bacteriostatic action but narrow bactericidal spectrum, namely, the antibacterial agent has poor action on gram-negative bacteria such as pseudomonas aeruginosa and the like and basically has no effect on mycobacterium tuberculosis and bacterial spores; can only inactivate lipophilic viruses, but has poor effect on hydrophilic viruses.

Triclosan is a highly effective broad spectrum antimicrobial agent. Triclosan has a certain antimicrobial spectrum but is biased towards bacteriostasis. Triclosan acts more strongly on gram-positive bacteria (including M RSA) than on gram-negative bacilli, particularly Pseudomonas aeruginosa. Triclosan has some activity against mycobacteria and candida, but is less active against filamentous fungi. Numerous studies have shown that the reduction in colony count after hand washing with triclosan is lower than that of chlorhexidine, povidone-iodine and ethanol products.

Patent CN02817591.3 antibacterial wound dressing is an antibacterial wound dressing used with silver ions attached to some but not all of the exchangeable sites and having a substantially uniform silver ion distribution over the exchangeable sites or made of gel-forming fibres such as carboxymethylcellulose or alginate fibres. Silver-coated fibres for use in wound dressings may be produced by contacting a set of precursor gel-forming fibres having exchangeable sites with a solution containing silver ions in an amount to link silver ions to some but not all of the exchangeable sites, without causing irreversible gelling of the fibres, all of the set of precursor gel-forming fibres being contacted with all of the solution containing silver ions substantially simultaneously.

When in use, the packaging bag is torn, the medicine bag is torn from the medical cotton gauze, then the medicine bag is torn, the medicine is coated on the medical cotton gauze according to the dosage specification, and then the medical cotton gauze is applied to the affected part.

Patent CN2004200562829 discloses a medical ozone therapeutic apparatus. Relates to a medical treatment instrument. The ozone generator is small in size, can continuously generate gaseous ozone with certain concentration and pressure in high quality, directly sprays high-concentration ozone gas to a body surface wound or a wound surface to form a relatively closed space and diffusion force, does not increase the pain of a patient, does not hurt the patient, and reduces treatment cost. The device comprises a shell, a ceramic ozone generator, a control circuit, a micro gas suction pump, a spray pipe and a closed cover; wherein, a ceramic ozone generator, a control circuit and a micro air compressor are arranged in the shell; the nozzle interface on the shell is connected with the spray pipe, and the spray pipe is connected with the closed cover; the sealing cover is an elastic cover; the control circuit includes an alternating current circuit and a direct current circuit. The sealing cover is covered on the wound or the wound surface, the micro gas suction pump and the ceramic ozone generator continuously work, and the ozone continuously enters the sealing cover through the spray pipe to form certain diffusion force. The bacteria and virus can be quickly inactivated.
