With this configuration, "Effect B: The surface member 2 has a heat insulating performance that performs at least one of the functions of suppressing heat conduction in the front and back directions of the surface member 2 and the function of blocking heat by radiation." Due to the structure of the flexible surface member 2a, it not only has the above-mentioned effect (long-term cooling maintenance/comfortable wearing effect), but also has the "long-term cooling maintenance/comfort effect" which has particularly significantly improved long-term cooling performance. "Comfortable wearing effect and further cooling maintenance performance effect" can be obtained.

In general, the thermal conductivity of ordinary plastic materials such as polyethylene, polystyrene, polyurethane, silicone rubber, etc. is about 0.15 W/mK to about 0.35 W/mK, whereas foaming these plastics The thermal conductivity of a porous plastic foam material having a large number of microscopic cells is about 0.025 W/mK to about 0.08 W/mK. That is, the plastic foam molded material has a lower thermal conductivity than a normal non-foamed plastic molded material, and is used as a thermally conductive heat insulating material that has excellent heat insulation performance. For example, polyethylene has a thermal conductivity of about 0.2 to about 0.3 W/mK, and silicone rubber has a thermal conductivity of about 0.3 to about 0.4 W/mK.
Additionally, in general, nonwoven fabrics and woven fabrics made of fibers made from polyester, polyamide, polyacrylic, etc., and natural fibers such as wool, cotton, etc., have fine voids as these fibers intertwine with each other. Due to this, it has a lower thermal conductivity than bulk molded materials of these materials, and has excellent heat insulation performance.

(iii) As the laminated nonwoven fabric material formed by laminating a plurality of nonwoven fabrics, a laminated nonwoven fabric material formed by laminating two or more nonwoven fabrics made of the above short fibers can be used.
In addition to the above, for example, a micropore-forming fiber material can be used, which is made by knitting fibers (long fibers) with microscopic cavities in a desired weaving or knitting method.
Such a heat conductive heat insulating material has a property of suppressing heat conduction in the front and back directions of the sheet. Therefore, sheets made of thermally conductive and insulating materials have the effect of trapping the cold air from the cooling medium inside due to the low thermal conductivity of the thermally conductive and insulating materials and suppressing the cold air escaping to the outside. B: A head cooling device which has effect (a) and also has excellent long-term cooling maintenance performance, provides long-term cooling maintenance and comfortable feeling of wearing, and has further cooling maintenance performance effects.

In addition, the metal sheet formed into a smooth plane has radiant properties that reflect heat. Therefore, sheets made of radiant heat conductive heat insulating material have the effect of trapping the cold air from the cooling medium caused by the heat conductive heat insulating material inside due to the low thermal conductivity of the heat conductive heat insulating material, and suppressing the cold air escaping to the outside. , by uniformly conducting the cold air emitted from the cooling medium in the plane direction on the metal surface due to the metal film radiation insulation material, it suppresses the variation in the plane direction of the cold air, and the cold air from the cooling medium is transferred internally by radiation from the metal surface.

In general, when a human body part (e.g., a hand) is inserted into a container with an air atmosphere at a low temperature of about 0°C, it is necessary to endure the coldness and keep the hand in the low-temperature atmosphere for about 5 minutes or more. I can do it. However, if a human body part (for example, a hand) comes into contact with the surface of a plastic molding material at a low temperature of about 0°C, the coldness will become unbearable and the surface of the plastic molding material will touch the surface for more than about 1 minute. It is difficult to maintain contact. In this way, when cold air comes into contact with the human head, cold air from a gas such as air can withstand the cold air for a longer period of time than cold air from a solid material such as a molded material. , the cold sensation felt in the human head tends to be suppressed. That is, the direct transmission of cold air from the cooling medium is suppressed, and the effect that the cold air on the side of the human head can be maintained at a desired cold air temperature for a long period of time is obtained.

That is, when the supercooling suppression void forming member 82 is constructed of a mesh plastic molded material formed in a mesh shape (r), [Effect rule-r: due to mesh-shaped through holes] The air layer in the void has the effect of suppressing the direct transfer of cold air from the cooling medium, so that if the cold air temperature of the cooling medium is too cold, below about 2°C, the cold air of the cooling medium will be transferred to the plastic. In addition to preventing direct contact with the scalp of the head through the solid body, the intervening air created by the mesh-shaped through holes allows the cold air to remain at a temperature of about 2℃ to 15℃, which is comfortable for the human head, for a long time. It becomes possible to feel the time, and as a result, the effect of maintaining the cold air on the side of the human head at a temperature of about 2°C to 15°C, which feels comfortable, for a long time is obtained.
In addition, as the supercooling suppression void forming member 82, (s) a plastic molded material having flexibility enough to be bent and having through holes formed therein, and/or (v) formed in a mesh shape. [Effect rule-sv: Effect rule-r mentioned above (the air layer caused by the through holes suppresses the direct transmission of cold air from the cooling medium) ) effect, and also has flexibility to the extent that it can be bent, so that the supercooling suppressing head side inner surface member 8 can be deformed according to the shape of the human head and can be attached to the human head. Thus, the wearer does not feel the hardness caused by the supercooling suppressing head side inner surface member 8, and the wearer can enjoy a comfortable wearing feeling even when worn for a long time.

In addition, as the supercooling suppression void forming member 82, (t) a flexible and/or elastic mesh plastic made of a plastic foam molded material and having flexibility and/or elasticity and formed in a mesh shape. When the molding material is configured, [Effect rule-t: the above-mentioned effect rule-r (the air layer caused by the through hole suppresses the transmission of cold air from the cooling medium) effect, and the effect rule-s (By having flexibility to the extent that it can be bent, the supercooling suppressing head side inner surface member 8 deforms according to the shape of the human head, and can be attached to the human head, giving the wearer a supercooling effect.) It is possible to obtain a comfortable wearing feeling even when worn for a long time without feeling the hardness caused by the restraining head-side inner surface member 8, and it also makes contact with the human head. The mesh skeleton is made of a plastic foam molded material, which has insulation properties, which further suppresses the transmission of cold air from the cooling medium, thereby suppressing the excessively cold feeling of cooling to the wearer. Furthermore, it is possible to obtain a comfortable wearing feeling even when worn for a long time.

In addition, when the void forming member 82 for overcooling suppression is composed of (w) a void forming fiber material having a raschel-like and/or double raschel-like through hole, [effect rule w: as described above] The effect of rule-r (the air layer caused by the through holes suppresses the transmission of cold air from the cooling medium), and the effect of rule-s (by having flexibility to the extent that it can be bent, it suppresses supercooling) The head side inner surface member 8 deforms according to the shape of the human head, and can be attached to the human head, so that the wearer does not feel the hardness caused by the overcooling suppressing head side inner surface member 8. A comfortable wearing feeling can be obtained even when worn for a long period of time.In particular, voids having relatively thick raschel-like and/or double raschel-like voids can be obtained. By configuring the member made of formed fibers, it is possible to suppress the excessively cold feeling of cooling to the wearer, and furthermore, it is possible to obtain a comfortable wearing feeling even when worn for a long time.
In addition to the void-forming fiber member having russell-like through holes, a mesh-like breathable fiber material having air permeability and/or voids made of a non-woven fabric having air permeability and coarse bulk density may be used. An air-permeable void-forming fiber material formed by laminating formed fiber materials, etc., having voids and having air permeability, can also be preferably implemented. As a result, the effect of ``effect rule-aw: a head cooling tool that optimally exhibits the above-mentioned effect rule-w'' can be obtained. In particular, by configuring a laminated mesh-like breathable fiber member having a desired mechanical strength, a head that has the desired mechanical strength and optimally exhibits the above-mentioned "effect rule W" is used. A cooling device is obtained.

In addition, as the overcooling suppression void forming member 82, without being limited to the above, (x) an uneven forming sheet material formed by forming a large number of convex portions and concave portions on the surface of a cloth or plastic film sheet may be used. A head cooling device with a cooling member can also be preferably implemented, and with this configuration, [Effect rule At the same time, the air layer caused by the recesses suppresses the direct transmission of cold air from the cooling medium, suppressing the too cold feeling of cooling to the wearer, and furthermore, even when worn for a long time. , the effect of making it possible to obtain a comfortable wearing feeling] can be obtained.

- More preferably, a head cooling device for cooling the scalp of a user to whom a therapeutic agent used in the treatment of diseases such as cancer treatment has been administered, which when worn on the human head cools the cooling medium. However, it is preferable to use a head cooling device which is formed so as to be able to be worn over at least the human head, including the area where hair grows, and which is formed so as to be able to cool the scalp.

With the configuration of [Subordinate configuration 53], [Effect 2: With the configuration formed to be able to cool the scalp of the human head, when it is attached to the human head, cold air caused by the cooling medium escapes from the surface member 2. The cooling performance for cooling the scalp is suppressed, efficiently cooling the human scalp, and maintaining cooling performance for a long period of time. It has the effect of "maintaining cooling for a long time and feeling comfortable to wear", such as not restricting the user's movements and feeling comfortable to wear.
In particular, when used as a head cooling device to cool the scalp of the user who has been administered therapeutic drugs during treatment with therapeutic drugs such as anti-cancer drugs, it is said to have the effect of maintaining cooling for a long time and feeling comfortable to wear. ”, and in particular efficiently cools the entire head region including the parietal region, frontal region, occipital region, left temporal region, right temporal region, etc., and/or the head surface where hair grows and/or the scalp. As a result, the blood vessels near the hair follicles and/or hair roots are constricted, reducing the blood flow that flows near the hair follicles and/or roots. The amount of the anticancer drug used can be reduced, thereby providing a head cooling device that can be expected to have a "hair loss suppressing effect that suppresses hair loss caused by anticancer drugs."

When the head cooling device is used as a head cooling device for cooling the scalp of a user to whom a therapeutic agent used in the treatment of a disease such as cancer treatment has been administered, the following configuration is preferable.
- When attached to the human head, it is possible to cool the entire head, and the surface temperature of the inner surface of the head cooling device located on the scalp side and/or hair side of the human head is about 2 to about 2. A head cooling device that is configured to maintain a temperature in the range of 15° C. for 120 minutes or more is preferred and practicable.
- Preferably, the surface temperature of the inner surface of the head cooling device located on the scalp side and/or hair side of the human head is preferably 13°C or lower, more preferably 10°C or lower.

It is also known that hair loss is inhibited by inhibiting the absorption of hair into the skin.
When the head cooling device is attached to the human head, the effect of suppressing hair loss improves as the temperature of the scalp side on the inner surface of the head cooling device decreases. However, the temperature of the head cooling device If the temperature becomes too low, the wearer tends to find the cold air of the cooling medium "uncomfortable" and find it difficult to wear it for a long time.
According to medical professionals or known literature, it has been reported that by cooling the scalp temperature to about 19° C., the effect of suppressing hair loss on the scalp can be suitably obtained. It has also been reported that when a head cooling device is attached to the human head and the surface temperature of the head side of the head cooling device is approximately 15°C or lower, the scalp temperature drops to approximately 19°C or lower. ing.
It has been confirmed that by cooling the scalp temperature to about 15° C. or lower, hair loss can be suppressed. It has also been reported that, particularly preferably, by cooling the scalp temperature to about 13° C. or lower, the effect of suppressing hair loss is even more pronounced.

It is known that it is possible to reduce the amount of anticancer drugs administered to patients, thereby achieving a hair loss suppressing effect that suppresses hair loss caused by anticancer drugs. /Or as the temperature of the scalp increases, the constriction of blood vessels decreases, reducing the amount of anti-cancer drugs administered for chemical treatment of cancer patients that flow near the hair follicles and/or hair roots. It is also known that the hair loss suppressing effect that suppresses hair loss caused by cancer drugs tends to decrease.
As a request from medical professionals, when the head cooling device is attached to the human head, the surface temperature of the inner surface of the head cooling device located on the scalp side and/or hair side of the human head is approximately There is a need for a head cooling device that is configured to maintain a temperature in the range of 2 to about 15° C. for 120 minutes or more.
As the surface temperature of the inner surface of the head cooling device located on the scalp side and/or hair side of the human head becomes lower than about 15°C, the head surface where hair grows and/or the scalp are efficiently cooled. As a result, the blood vessels near the hair follicles and roots of the scalp are constricted, reducing blood flow, and the anticancer drugs administered for chemical treatment of cancer patients flowing near the hair follicles and hair roots. It is said that the effect of suppressing hair loss caused by anticancer drugs tends to increase.
