Description

Technical Field

[0001] This invention belongs to the field of public health and disinfection technology, specifically relating to a method for disinfecting scabies-affected environments using insecticidal fumigants (finished products). Background Technology

[0002] Scabies is a highly contagious skin disease caused by the scabies mite (Sarcoptes scabiei). It is commonly found in densely populated and relatively enclosed environments, such as nursing homes, boarding school dormitories, prisons, and military barracks. The scabies mite spreads through direct contact with the skin of infected individuals or indirectly through contact with contaminated clothing, bedding, and other items. Its transmission is extremely rapid; once an infection occurs, it can easily spread quickly within a group, causing large-scale outbreaks. This not only seriously affects the physical health of residents and students but also significantly impacts their daily lives, studies, and mental well-being, and may even trigger social panic and instability.

[0003] Traditionally, methods for eliminating scabies include high-temperature steaming, chemical spraying, and ultraviolet (UV) irradiation. However, these methods have many limitations in practical application. While high-temperature steaming is effective in killing scabies mites, the process is cumbersome, requires a large amount of heat and time, and may damage clothing, bedding, and other fabric materials, shortening their lifespan. Chemical spraying poses problems such as pesticide residue, pungent odor, and potential harm to the environment and human health, especially for children, the elderly, and those with sensitive constitutions, as it can easily trigger allergic reactions or other adverse effects. Although UV irradiation has a killing effect on some microorganisms, its effectiveness against scabies mites is not significant, and it requires long irradiation times and specific equipment conditions.

[0004] Even more serious is that under conditions where high-temperature disinfection is limited (such as a lack of sufficient heat sources or power supply) or in unfavorable weather (such as the rainy season or cold season), the difficulty and cost of implementing traditional disinfection methods will increase significantly, and they may even fail to achieve the expected disinfection effect. In addition, long-term reliance on chemical agents for disinfection may lead to drug resistance in scabies mites, further exacerbating the difficulty of disinfection work.

[0005] Therefore, finding a low-toxicity, efficient, economical, and easy-to-operate method for scabies eradication is of great significance for controlling the spread of scabies and protecting public health. Especially in densely populated areas, developing a disinfection technology suitable for large-scale application can not only effectively block the transmission chain of scabies but also reduce disinfection costs and potential harm to the environment and human health, demonstrating broad application prospects and social value. Summary of the Invention

[0006] To address the problem of effective disinfection during scabies outbreaks in densely populated areas with heavy clothing, unfavorable weather, and limited high-temperature disinfection conditions (such as nursing homes, boarding school dormitories, and prisons), this invention provides a method for environmental disinfection using a fumigant containing 5% cypermethrin. The method involves applying the fumigant to a contaminated, enclosed environment to kill scabies mites. Cypermethrin, the active ingredient in the fumigant, is a highly effective and low-toxicity pyrethroid insecticide commonly used for controlling agricultural and sanitary pests. Through the volatility of the agent or the formation of an aerosol by spraying, the active ingredient diffuses within the enclosed space, acting on the nervous system of the pests and causing their death. Prior to this invention, there was a lack of efficient, economical, and easy-to-operate methods for disinfecting scabies-affected environments in densely populated areas with limited high-temperature disinfection conditions. This invention utilizes the high-temperature fumigation properties of cypermethrin to effectively kill scabies mites in a closed environment. It has the advantages of low toxicity, short disinfection time, simple operation, and low time and economic costs. Practical verification shows that, without external input, there was no recurrence after a 6-month follow-up, demonstrating a significant disinfection effect.

[0007] This invention discloses a method for disinfecting scabies-affected environments using a fumigant insecticide. The fumigant insecticide commonly used is a fumigant insecticide containing 5% cypermethrin, selected according to the product instructions.

[0008] This invention also discloses specific procedures for disinfecting scabies-affected environments using a fumigant containing 5% cypermethrin, including disinfection materials, pre-disinfection preparation, the disinfection process, and post-disinfection treatment. Disinfection materials include a fumigant containing 5% cypermethrin, a lighter, and an ignition stick.

[0009] Preparations before disinfection include:

[0010] (1) Clean up the site: Remove food, tableware, pets, etc., cover or move electrical appliances and precision instruments, turn off the power and gas, and ensure that there are no flammable or explosive materials in the disinfection environment.

[0011] (2) Plan escape routes: Determine the placement point of the smoke insecticide (choose the center of the room, away from flammable materials such as curtains and sofas), reserve a passage for quick exit, and set up obvious warning signs.

[0012] (3) Personal protection: Operators must wear masks, gloves and long-sleeved clothing to avoid direct contact of smoke with the skin and respiratory tract.

[0013] The disinfection process includes:

[0014] (1) Calculate the amount: Calculate the amount of smoke insecticide required based on the size of the space. Generally, one smoke insecticide is needed for every 20 cubic meters of space.

[0015] (2) Ignition and Placement: Lay the smoke insecticide on its side, ensuring the bottom hole is open. Use a lighter to light the ignition rod and then ignite the smoke agent. If an open flame appears, extinguish it immediately; it will then produce smoke. Place the lit smoke insecticide in the center of the room, away from food, electrical appliances, and sources of heat.

[0016] (3) Close doors and windows: Ensure all entrances and exits are sealed to allow the smoke to diffuse fully indoors. The fumigation time is generally 2-4 hours.

[0017] Post-disinfection treatment includes:

[0018] (1) Ventilation to dissipate smoke: After the action time is reached, open the outdoor windows and doors first, keep the ventilation for at least 2 hours, and enter the room only after the smoke has completely dissipated.

[0019] (2) Clean the environment: After entering, wipe the tabletop, countertop and other high-frequency contact areas with a damp cloth, and clean the tableware and kitchen utensils to avoid residual chemicals.

[0020] (3) Dispose of residue: After the smoke insecticide has completely cooled, put the residue into a sealed bag and discard it as hazardous waste or according to the product instructions.

[0021] Post-disinfection effectiveness evaluation: After disinfection, a detailed physical examination and follow-up are conducted to ensure that no scabies reinfection occurs in the disinfected room. The follow-up period is generally as follows: the first post-disinfection evaluation is conducted on the 5th, 12th and 19th day after treatment, and then once a month for a total of 6 months.

[0022] This invention also discloses a method for disinfecting scabies-affected environments using a fumigant insecticide, comprising applying a fumigant insecticide containing 5% cypermethrin to a contaminated, enclosed environment to kill scabies mites. Cypermethrin kills the scabies mites by acting on their nervous system.

[0023] Cypermethrin belongs to the pyrethroid insecticide class. Its chemical structure contains specific active groups that can bind to sodium ion channels on the nerve cell membrane of scabies mites, interfering with the transmission of nerve impulses, causing scabies mites to become overexcited, spasm, and eventually die.

[0024] In one embodiment of the present invention, preferably, the smoke insecticide (finished product) is a 5% smoke agent, which facilitates the calculation of dosage and operation.

[0025] In one embodiment of the present invention, preferably, the smoke insecticide is laid on its side during operation to ensure that the bottom cavity is open.

[0026] In one embodiment of the present invention, preferably, during operation, the ignited smoke insecticide is placed in the center of the room to facilitate full diffusion.

[0027] In one embodiment of the present invention, preferably, during the operation, the room is kept well sealed to avoid leakage of the agent and affecting the disinfection effect.

[0028] In one embodiment of the present invention, it is preferable that the fumigation time be kept at 2-4 hours to facilitate thorough disinfection.

[0029] This invention also discloses the application of a fumigant for environmental disinfection in scabies cases, specifically in densely populated areas such as nursing homes and dormitories of fully residential schools. In practice, in 18 densely populated areas (16 nursing homes and 2 schools), with 1095 patients, 1000 beds, and 270 rooms, three rounds of disinfection were conducted (on the 5th, 12th, and 19th days of treatment, respectively). A 6-month follow-up showed no recurrence without external exposure.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] (1) High efficiency: Fog insecticide containing 5% high efficiency cypermethrin can quickly kill scabies mites and cut off the transmission route.

[0032] (2) Low toxicity: It has low toxicity to the human body and will not cause serious harm to human health under normal use. It is especially suitable for the elderly with weak immunity and students whose bodies are still developing.

[0033] (3) Easy to operate: No complicated equipment and technology are required. The dosage can be determined according to the instructions, which reduces the difficulty and intensity of disinfection work.

[0034] (4) Low cost: Both time and economic costs are relatively low, making it suitable for large-scale environmental disinfection work.

[0035] The method for disinfecting scabies-affected environments using the fumigant insecticide of the present invention is flexible in operation and adaptable to different locations and environmental needs.

[0036] This invention provides a method for eliminating scabies-contaminated environments. Effective elimination can be achieved by directly applying a fumigation agent (finished product), avoiding the problems of complex operation, high cost, and stringent environmental requirements that may exist in traditional elimination methods. It can quickly and efficiently complete the elimination task in densely populated and limited places, reducing the risk of scabies transmission. Attached Figure Description Figure 1 The first step is to close the windows tightly, and cover them with plastic film if necessary. Figure 2 The second step is to ignite the smoke insecticide bombs in each room and place them stably on a flat surface. Figure 3The third step is to open windows and doors to ventilate the room after the smoke insecticide is finished, allowing the smoke and odor to dissipate completely. Detailed Implementation

[0037] To make the implementation of this scabies disinfection solution clearer and more understandable, the specific implementation method of the scabies disinfection solution of the present invention will be described in detail below with reference to the specific operation steps.

[0038] The following description details each step of the disinfection process and the required materials to facilitate a full understanding and implementation of the invention. Those skilled in the art can make appropriate adjustments based on actual circumstances without departing from the spirit of the invention; therefore, the invention is not strictly limited to the specific implementation steps disclosed below.

[0039] Among existing scabies disinfection methods, high-temperature disinfection is subject to significant limitations, especially in densely populated areas with heavy clothing and inclement weather, such as nursing homes and boarding school dormitories, where it is difficult to implement. Traditional methods may suffer from incomplete disinfection, complex operation, or high costs.

[0040] To address the aforementioned problems, this invention employs an insecticidal fumigant (taking a fumigant containing 5% cypermethrin as an example) for environmental disinfection. This method has advantages such as low toxicity, short disinfection time, simple operation, and low time and economic costs, and is particularly suitable for scabies disinfection in enclosed environments.

[0041] This invention provides a specific implementation method for scabies disinfection, which effectively kills scabies mites in the environment through cypermethrin fumigation, reducing the risk of scabies transmission. This method not only avoids the limitations of high-temperature disinfection but also greatly reduces the risks and operational difficulties during the disinfection process, and demonstrates significant clinical disinfection effects.

[0042] Furthermore, it should be noted that the smoke insecticide used in this invention (containing 5% high-efficiency cypermethrin) belongs to the class of highly effective and low-toxic pyrethroid insecticides. Compared with other pest control products in the prior art, it has better volatility and diffusion, and can more effectively kill scabies mites hidden in the environment.

[0043] In one embodiment, the present invention provides the following specific operating steps for using a fumigation method with a smoke insecticide (finished product) for scabies disinfection:

[0044] 1. Preparation before use: Clean up the site, including removing food, tableware, pets (including fish, birds, etc.), covering electrical appliances and precision instruments, and turning off the power and gas. Plan an escape route by determining the placement point of the smoke bomb (choose the center of the room, away from flammable materials such as curtains and sofas), and leaving a passage for quick evacuation. Personal protection: Disinfection personnel must wear masks, gloves, and long-sleeved clothing to avoid direct contact of smoke with the skin and respiratory tract.

[0045] 2. Ignition and Evacuation: Ignite the smoke bomb according to the product instructions (usually by igniting the fuse or pressing the start valve), immediately place it on a stable surface, and quickly evacuate the room. Close all doors and windows tightly, ensuring all entrances and exits are sealed, allowing the smoke to fully diffuse indoors. The effective time is as indicated on the product label (generally 2-4 hours).

[0046] 3. Post-use disposal: After the activation time has elapsed, open outdoor windows and doors to maintain ventilation for 1-2 hours, and wait until the smoke has completely dissipated before entering. Once inside, wipe frequently touched areas such as tabletops and countertops with a damp cloth, and wash tableware and kitchen utensils to avoid residual chemicals. After the smoke bomb has completely cooled, place the residue in a sealed bag and dispose of it as hazardous waste or as per the product instructions.

[0047] 4. Disinfection Plan and Implementation: Comprehensive disinfection will be carried out in densely populated areas (such as nursing homes and boarding school dormitories) three times, on the 5th, 12th, and 19th days of treatment. A designated person will be responsible for the disinfection work to ensure standardized and safe procedures. Detailed records will be kept of the time, location, dosage, and effectiveness of each disinfection session for follow-up tracking and evaluation.

[0048] 5. Safety Precautions: Do not use in areas where people or pets are present. Operators must wear rubber gloves to avoid direct skin contact with the disinfectant. During disinfection, ensure food, drinking water, and personal belongings are kept away from the disinfection area to prevent contamination. Keep away from fire sources and high-temperature environments. After disinfection, ensure thorough ventilation to avoid irritation or harm from residual disinfectant. If fumes are accidentally inhaled or come into contact with skin, immediately move to a well-ventilated area. If symptoms are severe, seek medical attention promptly. Elderly individuals, children, and those with respiratory illnesses should be temporarily moved to a safe area during disinfection.

[0049] 6. Effectiveness Evaluation and Follow-up: After disinfection, the effectiveness of disinfection will be evaluated through subsequent case monitoring. Follow-up visits will be conducted within 6 months after disinfection to confirm no recurrence of scabies without external source input.

[0050] Through the above specific implementation methods, the present invention provides a scientific, reasonable and easy-to-operate scabies disinfection solution, which aims to ensure effective control of the spread of scabies in densely populated places and protect the health and safety of people.
