Description

  The present invention relates to a cool structure with a simple structure capable of temporarily storing an object to be cooled in a low temperature state. In particular, since a dead body needs autopsy for various reasons, it cannot be temporarily accommodated in its original form. It is suitable for storage and storage of corpses, etc., is lightweight and convenient to carry, has high cooling efficiency, prevents the odor of the corpses from being diffused, and prevents the corpses from being damaged.

  In the event of an accident associated with an earthquake, fire, flood, or other disaster, or a fatal accident such as a traffic accident, the body must be transported from the place of death to a place where payment or autopsy is performed. In addition, there may be cases where the body cannot be immediately housed in its original form, such as burial, for inspection after transportation, etc. In such a case, the body is surrounded by a blanket or sheet and placed on a stretcher or in a sleeping bag shape. It was stored in a bag and stored in a temporary morgue. However, in the case of a body that has received various injuries, such as an accident body due to various disasters, or under severe weather conditions such as high temperatures in summer, it is necessary to prevent the body from being painful.

In such a case, the simplest measure to prevent the pain of the corpse conventionally is to place the corpse in a closed space such as a bag and put a coolant such as a heat storage agent or lump dry ice in the tub to cool the inside of the jar at a low temperature. Was to keep on.
However, in order to achieve a sufficient purpose, frequent replenishment of the coolant is necessary, particularly in the high temperature period, which increases the labor and cost. In addition, dry ice must be handled with care because it will be damaged if it is brought into direct contact with the body, and it must be taken out immediately before cremation because dry ice is difficult to burn. There were problems such as excessive release of carbon.

Various devices including a cooling device with a refrigerant compressor using a cooling cycle based on refrigerant compression and expansion have been proposed.
Examples of such devices include, for example, Patent Document 1 (Japanese Patent Laid-Open No. 1-97455), Patent Document 2 (Japanese Patent Laid-Open No. 2-95366), Patent Document 3 (Japanese Patent Laid-Open No. 4-244153), and the like.
All of these apparatuses are of a type in which cold air is produced by the cooling device, the cold air is supplied into or around the cage containing the body, and the body in the cage is cooled.

In Patent Document 4 (Japanese Patent Laid-Open No. 9-253141), a cool air source (specifically, cooling using a cooling cycle by compression / expansion of a refrigerant) is applied to a body storage storage bag having heat insulation and airtightness. A dead body introduced into the storage bag by introducing cool air from a device, or an electronic cooling device utilizing the Peltier effect), and introducing a deodorizing and sterilizing fluid such as ozone into the storage bag from the deodorizing and sterilizing fluid forming means Means for preventing pain are disclosed.
Further, in Patent Document 5 (Japanese Patent Laid-Open No. 9-286701), an inert liquefied gas such as liquefied carbon dioxide gas or liquefied nitrogen is injected from a liquefied gas source into a body storage bag having heat insulation and airtightness, A storage method is disclosed in which the inside of the bag is made substantially oxygen-free and the body is rapidly cooled by the adiabatic expansion phenomenon during injection.

JP-A-1-97455 Japanese Patent Laid-Open No. 2-95366 JP-A-4-244153 JP-A-9-253141 JP-A-9-286701

However, since the devices disclosed in Patent Documents 1 and 2 are of a type in which cold air is blown into or around the cage, the inside of the cage is in a pressurized state, and the odor of the remains is diffused to the outside together with the cold air. There is a problem.
In addition, since the basket and the refrigeration apparatus are housed in one protective case, there is a problem that the weight of the protective case increases, which is inconvenient for transportation and other handling.

In addition, the apparatus disclosed in Patent Document 3 stores a cage in which a body is stored and a refrigeration apparatus in a single protective case as in Patent Document 1, and sets an evaporator in which the refrigerant of the refrigeration apparatus circulates under the fence. It is arranged on the floor of the protective case located on the side, and has a configuration in which the dead body is cooled and held by cold air from the evaporator. Since the cooling effect is reduced because the body is cooled from the outside of the casket in which the body is stored, and the casket and the refrigeration device are stored in one protective case, the overall weight is increased, and transportation is carried out. Inconvenient.
Further, when the basket and the refrigeration apparatus are separated into separate units, only the evaporator remains on the tub side, and there is a problem that it takes a long time to start the operation after connecting the evaporator and the refrigeration apparatus main body.

  In addition, since the device disclosed in Patent Document 4 is of a type in which cold air is blown into the body storage storage bag, it has a return pipe of the cold air supplied to the storage bag, but as in Patent Documents 1 and 2, There is a problem that the odor of the corpse is diffused to the outside along with the cold air.

Further, in the storage method disclosed in Patent Document 5, when a liquefied gas in a high pressure state is injected into the bag body, a valve operation controlled extremely gently is required. For example, the volume of liquefied carbon dioxide expands about 280 times.
Therefore, since the internal pressure of the bag body may suddenly increase and rupture, it is necessary to add an accurate flow rate adjustment function or an excessive flow rate protection function to the open / close valve of the high pressure cylinder, and careful operation is required. There is a problem that the apparatus is complicated and expensive.

  In view of the problems of the prior art, the present invention is temporary when a cold object that needs to be kept at a low temperature, particularly a corpse, needs to be examined for various reasons and cannot be accommodated in its original form. It is suitable for storage and storage, etc., and has a heat insulating property, confidentiality, or more flexibility, is a lightweight storage container that is lightweight, easy to transport and handle, and has an odor An object of the present invention is to realize a cold insulation device having a simple cooling unit having a function of maintaining and maintaining the inside at a low temperature without being diffused.

In the cold / hot water outgoing pipe 722, the hot water pipe 722 a and the cold water pipe 722 b are connected to the heat transfer pipe 721 via the mix valve 726, and based on the temperature detection value of the temperature sensor 724 installed at the arrangement position of the heat transfer pipe 721. The thermo switch 725 is configured to control the temperature of the thermal mat 72 by operating the mix valve 726 to change the ratio of hot water and cold water flowing into the heat transfer tube 721.

As an example of use with such a device, if the upper body is warmed, the lower body is cooled, or the right arm is burned, the right arm is cooled, or only the abdomen is dieted. If you want to warm up or sweat, use only to warm up the abdomen.
As described above, in the third embodiment, the temperature of each thermal mat 72 can be freely controlled, so that the heating temperature or the cooling temperature for each part of the human body can be freely controlled. ) Is effective.

  According to the present invention, it is suitable for a case where a body is temporarily stored and kept at the time of autopsy, etc., and can prevent the body from being damaged and the odor of the body from being diffused. Therefore, it is possible to realize a cold insulation device that is lightweight and convenient to carry and has a simple structure and high cooling efficiency.
