Description

  The present invention relates to a method for storing and storing a dead body after confirming death by a simple method until cremation.

In Japan, when a person dies, it is usually buried after being cremated. The cremation is done after more than 24 hours have passed since the death confirmation by the doctor, so if left unattended during this time, the decay of the corpse will progress, the generation of off-flavor and the dirt from the mouth, nose or anus Leakage occurs.

  Therefore, generally when death is confirmed, each dead body opening is blocked with absorbent cotton, etc., and a large amount of dry ice is placed around the abdomen to maintain the body at a low temperature, thereby suppressing the progress of decay. Measures are taken.

Currently, the cooling of dead bodies by dry ice, which is generally adopted, actually has many problems. The first is that dry ice must be replenished several times before the cremation process. That is, since dry ice is vaporized and dissipated over time, it is essential to replenish it in order to maintain the cold insulation capacity. To replenish this, the bereaved family or funeral company staff have the disadvantage that they must be assigned 24 hours a day. Furthermore, there are many opportunities to touch the dead body at the time of fulfillment, there is a risk of infection by pathogenic bacteria, and it is necessary to be careful about wearing rubber gloves and discarding it, but it may cause discomfort to the bereaved family. Careful consideration is required, especially in summer, as dry ice supplements increase.

  The second problem when using dry ice is inconvenience during cremation. Normally, the dead body is stored, and the inside of the cage is filled with dry ice, so if you try to incinerate it in the crematorium heating furnace, the rise in the furnace temperature is delayed due to the cold insulation effect of dry ice However, it is inevitable that the incineration time will be greatly extended. In addition, there is a risk that sometimes poisonous dioxins are generated due to the effect of a decrease in the furnace temperature.

  There are further inconveniences associated with the use of dry ice, for example, because the dead body freezes here, the bereaved family feels uncomfortable, and dry ice condenses moisture and the surrounding area of the dead body is excessive The person who moves to the body and moves the body still feels uncomfortable, or it is not easy to arrange dry ice in a depopulated area.

  Another problem in the use of dry ice is carbon dioxide, which is regarded as a problem as a greenhouse gas, and has a sense of resistance to use in large quantities. For this reason, it is desired to significantly reduce the amount used or to develop a technology that does not use it.

  The present inventors have conducted various studies on a method for preventing corruption until the body after the death confirmation is subjected to cremation treatment, with the aim of developing a technology to replace dry eye ice cooling that currently includes many problems. As a result, it was found that the internal organs of the corpse can be easily inhibited by heat treatment by irradiation of electromagnetic waves such as microwaves and high frequencies.

  According to the present invention, it is possible to suppress the progress of decay by simply irradiating the body with electromagnetic waves for a short time, eliminating the troubles of replenishing dry ice or reducing the furnace temperature during cremation in the conventional method, and extremely saving labor and energy It is a processing method of a corpse.

  In contrast to the conventional method of suppressing decay by cooling a corpse, the method of the present invention is characterized by heat-treating a corporal portion that is exactly opposite. The present inventors first performed a detailed analysis on the decay process of biological bodies. As a result, it was confirmed that the part where rot occurred at an early stage was the so-called internal organs called five viscera and six viscera, and other parts did not rot rapidly. In addition, it was understood that the visceral part liquefaction or swelling occurred during this decaying process, resulting in a strange odor around the body, and further liquid leakage from the mouth, nose, anus and other openings due to increased abdominal pressure. . Therefore, it has been found that in order to suppress the decay of the corpse, it is only necessary to suppress the decay and alteration of the internal organs.

  Therefore, the present inventors have conducted various experimental studies on methods for inhibiting the decay of animal viscera such as livestock, and the viscera of animals are generally sensitive to heat treatment, and when heated, they easily condense and become non-aggregated. It became dynamic and found that subsequent corruption could be prevented. Therefore, if the corpse part is heat-treated in this manner, it is possible to stably prevent corruption without special treatment until cremation.

  However, when this heat treatment is applied to the human body, it is important that the skin on the outer surface is not burned out so as not to harm the feelings of the bereaved family.

  An electromagnetic wave having a frequency of about 3 MHz to 300 GHz is called a high frequency or microwave, and has a function of selectively acting on a specific substance and directly heating them. Household microwave ovens apply this principle.Since pottery dishes and plastics filled with rice do not absorb microwaves, the temperature does not change. ) Is heated because it absorbs microwaves. The present inventors examined various heating conditions of the internal organs by directly irradiating high-frequency waves and microwaves from the upper part of the skin using a carcass of a domestic animal simulating a human corpse. As a result, it was found that if these electromagnetic waves were used, the internal organs could be heated and passivated without damaging the surface skin, and as a result, the progress of decay was suppressed. In this case, the internal organ heating temperature is preferably 40 ° C. or higher in order to sufficiently obtain the effect of inhibiting corruption. There is no particular upper limit to the temperature, but there is almost no need to raise it to 80 ° C or higher.

  The high frequency or microwave frequency used here is not particularly limited in the present invention. Also, the microwave irradiation method is not particularly limited, and either a continuous or intermittent method may be used. Since there are individual differences in actual bodies, it is practically useful to install, for example, an optical fiber thermometer at the heating target position in order to increase the accuracy of the heat treatment.

According to the present invention, it is possible to suppress the decay and decay of the corpse by simply irradiating an electromagnetic wave such as high frequency or microwave for a short time, and it is possible to safely place the corpse until the cremation process. In addition, the effects of the present invention will become stronger if preservatives and the like are appropriately injected into the internal organs after irradiation with electromagnetic waves. Furthermore, if sterilization and sterilization of bacteria or the like that parasitize or inhabit the inside of the body or the surface using, for example, alcohol, ozone, ultraviolet light, etc. are performed at the same time, it is possible to suppress infection of pathogenic bacteria.
Hereinafter, the effects of the present invention will be described in more detail with reference to examples.

An agar jelly with a size of 320 x 280 x 200 mm (water content 96%) simulating the human internal organs between the electrode plates in a high frequency heating device with a frequency of 13.56 MHz having upper and lower electrode plates with a cooling function like a water pillow made of rubber This was continuously irradiated at an output of 2000 W, and the temperature rise conditions at the center (depth 100 mm) and surface layer (depth 20 mm) were measured using a fiber thermometer. As a result, there was almost no difference between the temperatures of the two parts during the temperature rise, and the central part reached 45.8 ° C. and the surface layer part reached 45.1 ° C. 19 minutes after the start of the temperature rise. In addition, since the agar surface part at this time was cooled by the water pillow, the temperature was kept at the cooling water circulation temperature (10 ° C.).
Therefore, from this simulation experiment, it can be confirmed that the internal organs can be heat-treated without burning the surface skin even when the human internal organs are directly irradiated with high frequency.

Using the same high-frequency heating apparatus as in Example 1, a chicken farm immediately after death with the feathers removed between the upper and lower electrode plates was set and a heating test was performed. When the high frequency output was continuously radiated at a constant 1000 W, the fiber thermometer reading inserted at a position 55 mm from the chicken skin increased almost linearly from the start of temperature increase, and reached 49.5 ° C. 10 minutes after the temperature increase. By the way, high-frequency irradiation was stopped. After finishing the heating, the chicken was taken out from between the electrode plates and observed for appearance, but no abnormality was observed in the epidermis. On the other hand, when the abdomen was opened and the inside was observed, it was confirmed that the internal organs such as the intestine were condensed and passivated.

A heating test was performed in the same manner as in Example 2 except that the high frequency output was 1500 W. As a result, the temperature of the internal organs of chicken reached 42 ° C. after 4 minutes of irradiation. After the irradiation, the same observation as in Example 2 was performed. As a result, the visceral part was condensed and passivated while the epidermis portion was not different from that before the irradiation.

Using the variable output microwave oven (frequency 2450 MHz), the same chicken farm heating test as that used in Example 2 or 3 was performed. At this time, the microwave was irradiated for 15 minutes in a pulse state of 1 second irradiation / 4 second pause at an output of 1500 W. The optical fiber thermometer inserted in the chicken belly indicated 46 ° C. at the end of microwave irradiation.
The chicken after heating was taken out from the microwave oven and the appearance was observed. As a result, there was no noticeable discoloration, burning, etc., and there was almost no influence of microwave irradiation on the surface skin. On the other hand, when the abdominal part was opened and the visceral part was observed, the subcutaneous fat part was not particularly changed, whereas the internal organs such as the intestine were condensed and passivated.

A chicken farm similar to that in Example 4 was set in the same microwave oven as in Example 4, and microwaves with an output of 600 W were continuously irradiated for 9 minutes. At this time, the optical fiber thermometer inserted in the chicken belly indicated 45 ° C.
The heated chicken was taken out of the microwave oven and the appearance was observed in the same manner as in Example 4. As a result, there was no noticeable discoloration, scorching, or the like. On the other hand, the viscera observed by opening the abdomen were coagulated and passivated as in Example 4.

The heat-treated chicken obtained in Examples 2 to 5 and the non-heat-treated chicken for comparison were placed in a temperature-controlled room at a constant temperature of 24 ° C. for 72 hours. After that, when the rotting situation of each chicken was observed, the non-heat-treated one gave off a strong off-flavor, the internal organs rotted and became muddy, and the filth that seemed to be part of the rot was exuded from the anus. Was. On the other hand, for the heat-treated chicken, there was almost no spoilage or off-flavor, and there was no particularly significant change with time in the surface skin.
