Description

Technical Field

[0001] The present invention relates to a cleaning and deodorizing method at a special cleaning site. More specifically, the present invention relates to a cleaning and deodorizing method at a body discovery site such as a site of a solitary death in an apartment or a single-family house, which is a special cleaning site in a narrow sense.

Background Art

[0002] At the site of special cleaning, various things that are not usually considered remain. That is, the body discovered after death decomposes and emits a strong stench of death. In addition, the body is covered with pests such as flies, maggots, and cockroaches, and the decomposed flesh has become lumps.

[0003] In such a case, regardless of the type of body, the body itself is taken away and disposed of by the police. On the other hand, the decomposed skin, the flowing putrefaction fluid and blood, and the fallen hair that have fallen off are left at the site as they are. Therefore, the disposal of these remaining things and the cleaning of the room contaminated by the remaining things must be carried out by the bereaved family or the house owner. Normally, at such a site, in addition to the mental shock, there are often a strong smell and a poor hygienic environment. In addition, the putrefaction fluid and blood emitted from the body often penetrate into the walls, floorboards, and under the floor, which causes the smell to never go away or pests to occur. Due to these circumstances, it is extremely difficult to take appropriate measures at the site of special cleaning without being an expert, and it can be said that it requires advanced technology. A technique related to a deodorizing method at such a special cleaning site is disclosed (Patent Document 1).

Embodiments for Carrying Out the Invention

[0014] The cleaning and deodorizing method at the special cleaning site of the present invention will be described. The cleaning and deodorizing method at the special cleaning site of the present invention includes a disinfectant treatment step of spraying and spreading a liquid disinfectant on the residues at the target location, a residue fixation step of spreading a fixing agent on the target location to fix the residues, a fixed residue removal step of collecting and removing the fixed residues, a sterilization cleaning step of spraying a liquid disinfectant on the target location for sterilization cleaning, a penetration step of spraying a liquid disinfectant on the target location to penetrate it, a disinfectant wiping step of wiping off body fluids and the like that are blown out together with the penetrated liquid disinfectant by warming the target location, a stain remover penetration step of applying a stain remover and allowing it to penetrate after sufficiently drying the target location, a stain remover wiping step of wiping off the stain remover, a neutralization cleaning step of performing neutralization cleaning of the stain remover with a cleaning agent, and a space deodorizing step of deodorizing the indoor space at the target location, and is characterized by comprising these steps. According to the present invention, without using ozone, it has the effect of being able to efficiently and safely perform hygienic treatment and removal of residues, decomposition and sterilization treatment of body fluids and the like, restoration of the original state and sterilization of the appearance of the target location, and deodorization of the indoor area.

[0015] The cleaning and deodorization method for special cleaning sites according to the present invention will be explained with reference to Figure 1. <<Hygienic handling and removal of remaining items (S1 to S4)>> In the present invention, a series of steps for hygienically treating and removing the remaining material include a disinfectant treatment step S1, a material solidification step S2, a solidified material removal step S3, and a disinfection and cleaning step S4.

[0016] The disinfectant treatment process S1 is a process of spraying or scattering a liquid disinfectant onto the remaining objects in the target area (hereinafter, spraying or scattering will be referred to as "spraying, etc."). In other words, although the body itself is taken away by the police, the place where the body was found and its surroundings (hereinafter referred to as the "target area") are left behind as remnants such as decomposed and crumbling skin, leaked putrefactive fluids and blood, and fallen hair. The remnants themselves and their surroundings emit a foul odor and are in an extremely unsanitary state due to bacteria and viruses. For these reasons, the disinfectant treatment process is carried out as a preliminary measure to roughly remove any remaining materials by spraying disinfectants or similar methods.

[0017] The liquid disinfectant used in the disinfectant treatment process S1 is not particularly limited as long as it is a disinfectant that can exert a strong bactericidal effect against bacteria and viruses contained in the remaining material, and various types can be used. As such liquid disinfectants, for example, chlorophenol-based disinfectants, alcohol-based disinfectants, and chlorhexidine-based disinfectants can be used, and chlorophenol-based disinfectants are preferred. Chlorophenol-based disinfectants such as orthobenzyl-parachlorophenol, orthophenylphenol, and para-tertia-amylphenol can be used individually or in combination. Alcohol-based disinfectants can be used, for example, ethanol, isopropyl alcohol, etc., either alone or in combination. Chlorhexidine-based fungicides, for example, chlorhexidine gluconate and chlorhexidine can be used alone or in combination.

[0018] The residual object fixing process S2 is a process in which a fixing agent is sprayed onto the residual object to fix it in place. In other words, a liquid disinfectant is sprayed onto the remaining material, and then a fixing agent is applied and stirred to turn the material into a muddy or solid state. The material fixing process is performed as a preliminary measure to allow the fixed material to be scraped up and removed all at once using a scraper or similar tool. The process of fixing the remaining materials does not need to be particularly limited as long as it is possible to fix the remaining materials, and various fixing agents can be used. As a fixing agent, one that mainly consists of a water-absorbing compound can be used. Examples of water-absorbing compounds include sodium polyacrylate, sodium polyacrylate, polyvinyl alcohol, polyacrylamide, diatom silica, and zeolite, and these can be used individually or in combination. The adhesive preferably contains a sterilizing component. This allows for more effective sterilization of the remaining material, and enables more hygienic subsequent treatment.

[0019] The solidified residue removal process S3 is a process for collecting and removing the solidified residue, which has become muddy or solidified while being sterilized by the sterilization treatment process S1 and the residue solidification process S2. The process for removing fixed debris is not particularly limited as long as it allows for the collection and removal of the fixed debris, and various methods can be used. In the process of removing solidified residue, this can typically be done by scraping up the solidified residue with a scraper and then removing it using a dustpan.

[0020] The sterilization and cleaning process S4 is a process in which a disinfectant is used as the cleaning solution to clean and sterilize the target area. In other words, after roughly removing the solidified residue, any remaining small pieces are collected and removed, and a liquid disinfectant is used during the collection and removal process to ensure complete removal of the residue and disinfection of the target area. The liquid disinfectant used in the sterilization and cleaning step S4 may be the same as that used in the disinfectant treatment step S1 described above. In the sterilization and cleaning process S4, the liquid antimicrobial agent is sprayed and wiped away. Depending on the condition of the target area, these spraying and wiping processes may be repeated to clean and sterilize the area. Furthermore, in the sterilization and cleaning process S4, cleaning can be performed by spraying a liquid disinfectant, using a launcher, brush, etc. to remove wax, or by collecting and removing material with a scraper.

[0021] <<Decomposition and sterilization of bodily fluids, etc., after disposal of remaining items (S5, S6)>> In the present invention, after processing the remaining material, steps for decomposing and sterilizing bodily fluids, etc. at the target site include a disinfectant penetration step S5 and a bodily fluid wiping step S6.

[0022] The disinfectant penetration step S5 is a process for disinfecting and cleaning not only the surface but also the deeper layers of the target area by penetrating it with a liquid disinfectant. It is also performed as a preliminary measure to wipe away any bodily fluids that have penetrated deep into the target area. In the disinfectant penetration process S5, a liquid disinfectant is applied and a treatment is performed to allow it to penetrate. As a measure to address this, one can apply a disinfectant and then allow a certain amount of time to pass through to allow the disinfectant to penetrate. Furthermore, in the disinfectant penetration step S5, it is preferable to cover the area with a sheet after applying the disinfectant and leave it to stand (sheet coating step). This allows the disinfectant to penetrate more easily, which has the effect of making the extraction of bodily fluids, etc., described later, more efficient. The sheet can be any type of material as long as it allows for penetration of the disinfectant. Various types can be used. Preferably, a disposable sheet can be used, and typically, a paper sheet can be used.

[0023] The bodily fluid wiping process S6 is a process in which the bodily fluids are extracted (extraction treatment process) along with the impregnated disinfectant and then wiped away. In other words, by performing the extraction procedure, the body fluids that are released along with the penetrating disinfectant are wiped away, while deep cleaning, disinfection, and deodorization are carried out. One method for extracting such bodily fluids is to perform a heating treatment (heating treatment process). That is, by heating the area where the disinfectant has been impregnated with a heat gun or the like, the bodily fluids will be forced out along with the disinfectant that has penetrated the interior. By wiping away these forced-out bodily fluids with a paper sheet or the like, the bodily fluids can be removed. Furthermore, if the area in question is a tatami mat, a sheet is placed over the area, and vibrations are applied using a vibrator (vibration treatment process), causing bodily fluids to spurt out. Since the spurted bodily fluids soak into the paper sheet, this series of operations effectively removes and wipes away bodily fluids.

[0024] <<Restoration and sterilization of the affected area's appearance>> In the present invention, steps for restoring the appearance of the target area to its original state and sterilizing include a stain remover penetration step S7, a stain remover wiping step S8, and a neutralization washing step S9.

[0025] The stain remover penetration step S7 is a preliminary step performed to penetrate the target area with a stain remover in order to remove the stain. In other words, after the disposal of remaining items and the decomposition and sterilization of bodily fluids, the target area is often discolored. Therefore, by removing stains from the discolored area, the appearance of the area is restored to its natural state (original condition), while also sterilization and deodorization are performed. In the stain removal process S7, after the decomposition and sterilization of bodily fluids, etc., following the treatment of remaining materials (after the bodily fluid wiping process S6), the target area is thoroughly dried before applying the stain remover, covering it with a sheet, and leaving it to stand. While checking under the sheet as needed, once sufficient stain removal is confirmed, the stain remover is wiped off (stain remover wiping process S8). The duration of this standing period can typically be 20 to 120 minutes, preferably 30 to 90 minutes, more preferably 30 to 80 minutes, particularly preferably 30 to 70 minutes, and most preferably 30 to 60 minutes. As for stain removers, there is no particular need to limit them as long as they can remove the stain; various stain removers can be used. As long as the stain remover is suitable for use on wooden floors, tatami mats, concrete, etc., there is no particular limit to the type of stain remover that can be used, and various stain removers can be used. Preferably, caustic soda, hydrogen peroxide, etc., can be used as such a stain remover.

[0026] After wiping off the stain remover, neutralization cleaning is performed (neutralization cleaning step S9). Neutralization cleaning can be performed by washing the area with water and drying it thoroughly.

[0027] <<Space Deodorization Process S10>> The spatial deodorization process S10 is a process in which, after the disposal of remaining items and the restoration of the target area to its original state, spatial deodorization is performed in the room where the target area is located (hereinafter simply referred to as "the room"). In other words, even after intensive sterilization and deodorization treatment has been carried out on the target area, odors usually remain in the room. Therefore, after the disposal of any remaining items, deodorization treatment is carried out again, which also serves to sterilize the room.

[0028] In the space deodorization process, this can be carried out by fumigation treatment using chlorine dioxide water (chlorine dioxide fumigation treatment process). In other words, it can be done by following the series of steps below. (1) Close the windows and make the room airtight. (2) Heat the room using an air conditioner or spot heater until the indoor humidity is around 15 to 20%. Maintain a temperature of approximately 30 to 35°C. (3) After confirming that the humidity has decreased sufficiently, open the windows in the room and ventilate for about 20 minutes. If necessary, use a circulating fan to expel any odors from the room to the outside. (4) Depending on the odor situation, repeat steps (1) to (3) (odor discharge process) two to three times. (5) Close the windows to make the room airtight, and use a spot heater or similar device to raise the indoor temperature and lower the indoor humidity. (6) Spray chlorine dioxide solution to fumigate the entire room. (7) After fumigation is complete, open the windows to allow for ventilation and use a circulating fan to dry the room for several days (2 to 3 days).

[0029] In the air deodorization process, this can also be carried out by spraying an agent whose main component is an oxidation catalyst. In other words, it can be carried out by the following series of steps (treatment step with a chemical containing a lamp oxidation catalyst). (1) A chemical agent is prepared by adding water to titanium iron oxide and an activator, and mixing it with an oxidation catalyst. (2) With the windows closed, apply the chemical from (1) thoroughly to the entire room. (3) After application, open the windows to allow for ventilation. Then, use a circulating fan to dry the room for two to three days. [Examples]

[0030] The present invention will be further explained with reference to the drawings.

[0031] Figures 2 to 6 illustrate the process of performing the cleaning and deodorizing method of the present invention at a special cleaning site.

[0032] 1. A powerful liquid disinfectant is sprayed onto the target area on the tatami mat (Figure 2, a). The powerful disinfectant used is an agent whose main components are orthobenzyl parachlorophenol and orthophenylphenol (product name: Tectrol, manufactured by von Schrader Japan Co., Ltd.). 2. Next, the adhesive is applied (Figure 2, b), and then mixed with a scraper to create a muddy consistency (Figure 2, c). The adhesive used contains sodium polyacrylate, silica silicate, and a fungicide (product name: Sanitia, manufactured by STAINSHEILED). 3. Use a scraper to gather up the muddy residue and remove it using a dustpan (Figure 2, d). 4. After removing the remaining objects, spray a liquid disinfectant to clean the surface of the area (Figure 2, e). Although the remaining objects have been removed, stains remain on the area (Figure 2, f).

[0033] 5. Spray the liquid disinfectant onto the target area and place a paper sheet on top (Figure 3, g). 6. Next, place a paper sheet on top and use a vibrator to vibrate and wipe away any bodily fluids that have soaked into the tatami mat, along with a disinfectant (Figure 3, h). 7. After removing bodily fluids, apply the stain remover (Figure 4, i), place a paper towel over it (Figure 4, j), and check the stain removal progress periodically. You can see that the stain has disappeared after stain removal (Figure 5, k). Caustic soda and hydrogen peroxide are used as stain removers (product names: Stain Remover A, Stain Remover B. Manufactured by iPS Corporation).

[0034] 8. Figure 5 shows the process of heating using a heat gun. While heating with the heat gun, wipe away any bodily fluids that spurt out with paper towels or rags.

[0035] 9. Figure 5 shows the deodorization process using a lamp oxidation catalyst solution. After evenly spraying the solution onto walls, ceilings, etc. (o,p), ventilation is performed using a circulating fan (q). The lamp oxidation catalyst used consists of titanium dioxide, apatite, peroxide, citric acid, and water (product name: Ecolala Megaclean / Ecolala Hybrid, manufactured by Global Ecology Co., Ltd.).

[0036] 10. Figure 6 shows the process of fumigation with chlorine dioxide solution. After removing odors from the room and drying it thoroughly, chlorine dioxide solution is sprayed and fumigation is performed. After fumigation, ventilation is carried out using a circulating fan or similar device.
