Description

[Detailed description of the invention] This invention is a head cooling device that can be placed over the patient's skull like a hat for medical treatment. The bag is filled with an organic cold-retaining material, which is then cooled in a household refrigerator and then used to store certain types of medicine using a type of cold pack that is applied to the patient's forehead or other affected areas. This invention relates to a head cooling device that can be effectively applied to the head to treat side effects caused by.

Some drugs that have been developed in recent years have a side effect that causes the patient receiving the drug to lose their hair, but as long as the side effect is not fatal, such as the hair loss mentioned above, the outstanding medicinal efficacy is Therefore, continuous administration of medication is often desired. Therefore, research is being conducted into ways to reduce the above-mentioned side effects as much as possible, and a clinical case has recently been reported in which the above-mentioned side effects can be prevented by forcibly cooling the patient's skull during the medication period.

The cold packs available on the market today are pillow-shaped or hanging bag-shaped, such as water pillows and ice packs, so they can only keep the cranium locally cool, and they can only be used when the patient is lying down. It can only be used in this condition. Furthermore, even if a cold storage device is made by filling a plastic sheet bag with chemical substances such as organic cold packs, which have recently been used in place of the aforementioned water pillows and ice packs, it is at best a headband type, so it retains cold locally. Even if it is possible to cover the entire circumference of the patient's skull, it cannot provide a complete cooling effect against the side effects of drugs as mentioned above, and moreover, it does not cover the entire circumference of the patient's skull, and it also does not allow it to fall off from the head when turning over or doing other movements. If I did that, I would have a lot of flaws.

In response to requests from the nursing community, the applicant has developed a head that can effectively keep the entire cranium cold in order to prevent the aforementioned side effects, and that does not cause pain to patients even when used for a long period of time. Request for cold storage equipment in 1984.
It was proposed in No. 6929 and Utility Application No. 56-62013, and its usefulness is being recognized clinically.
The inventor of the present invention has developed the present invention as a result of conducting studies aimed at further improving the cold preservation effect of the above-mentioned cold storage device.

Therefore, the purpose of this invention is to be able to more effectively insulate the entire skull, to prevent condensed water droplets from dripping, to prevent the hair and scalp from getting wet, and to prevent the wearer from coming off unnecessarily. The objective is to provide an easy-to-use head cooling device.

The gist of this invention is a cooling system consisting of a polygonal or circular unit cooling body piece that covers the top of the head, and a plurality of unit cold insulation pieces that cover the frontal, temporal, and occipital areas attached radially. A peripheral belt that brings the unit cold insulator pieces that cover the frontal, temporal and occipital areas into close contact around the cranium, and a parietal cold insulator piece. The upper and lower belts that can be hung on the chin to fit tightly against the top of the head, and the above-mentioned cold storage device prevent cold air from escaping to the outside as much as possible.
A hat-shaped insulating cap with a chin belt that is placed over the main body of the cold storage device to block outside air; a central part of the insulating cap is attached to the forehead, and both ends are attached to both sides of the insulating cap. It consists of a sizing band that engages with a locking part provided on the holder.

The main body of the cold storage device of the present invention is constructed so that it can cover the entire cranium when worn, and is always worn on the cranium. Furthermore, prior to installation, the main body of the cooling device is strongly cooled in a refrigerator. Therefore, if the internal ice pack has the property of freezing due to cooling, it will cause pain to the patient and other wearers.
Furthermore, it is difficult to fit the device closely to the cranium. Therefore, it is preferable that the ice pack mainly used in the cold storage device of the present invention does not lose its appropriate flexibility even when cooled in the freezer compartment. A suitable material is, for example, a hydrophilic hydrogel as disclosed in the invention disclosed in Japanese Patent Publication No. 52-48895, which is wrapped in a synthetic polymer material in the form of a W/O emulsion with little plasticity change due to temperature. It is something. Of course, any other known ice pack that retains its appropriate flexibility even with intense cooling may be used.

The above-mentioned cold pack is sealed and sealed in a bag made of a flexible sheet such as polyethylene or polyvinyl chloride to form a unit cold pack.

The main body of this cooling device can cover the entire skull when worn, and can be easily worn as it matches the dimensions of each person's skull.On the other hand, it can be folded to the minimum volume when cooled in a refrigerator/freezer. It is preferable that the configuration be such that it is possible to do so. Therefore, the main body of the cooler according to the present invention is divided into a plurality of unit cooler pieces as described above.

In addition, since the above-mentioned cold insulator is intended to be strongly cooled and installed, during use, moisture in the outside air condenses on the outer surface of each unit cold insulator piece due to the temperature difference with the outside air. Causes condensation. In order to eliminate the discomfort caused by dew condensation adhering to the hair and scalp, or dripping and wetting clothes, each unit cold insulator piece of the present invention is housed in a mesh bag made of flexible and water-repellent chemical fibers. inserted into. The size of the mesh of this mesh bag is such that condensed water droplets do not pass through the mesh due to their surface tension, but are forced onto the inner surface of the bag. In addition, each unit cold insulator can be inserted into and taken out from the mesh bag, allowing for replacement in the event of deterioration in the function of the cold pack or breakage of a piece of the cold insulator, as well as allowing it to be housed in a refrigerator with a lower bulk. Therefore, they can be taken out individually from the mesh bag and housed in a separated state. If each unit cold insulator piece is taken out from the mesh bag and cooled only in this way, dew condensation on the surface of the mesh bag can be avoided. Therefore, the mesh bag has a pocket-like form with an entrance and exit. Of course, the mesh bag is divided into the parietal region, frontal region, temporal region, and occipital region corresponding to each unit cold insulator piece, and one side below the forehead is radially arranged around the mesh bag in the parietal region. Sewn on.

Each of the mesh bags sewn radially around the top of the head has dimensional flexibility by being self-stretchable to a certain extent so as to fit different sizes of the patient's skull; If necessary, elastic strips may be attached to the side edges of the pericranial mesh bag.
In addition, in order to join the side edges together and completely surround the skull, for example, surface-adhesive fasteners commercially available under the names of Velcro Fastener (registered trademark) or Magic Fastener (registered trademark) may be used on the sides. Can be attached to the edge. Slide fastener instead of the above-mentioned surface-adhesive fastener,
Other known fasteners such as hooks, buttons or snaps may optionally be used.

In the main body of the cooling device of the present invention, the lower edge of the cold insulating piece for the forehead generally does not reach below the eyebrow line or at least the eyes of the person. The temporal cooling body piece should be long enough to cover the lower part of the cheek, as cooling of the superficial temporal (so-called temple area) artery, which branches from the carotid artery and ascends, is particularly effective in preventing scalp hair loss. It is preferable to have However, in this case, the temporal head cold insulator pieces will cover the ear wings, and the ear wings are susceptible to frostbite due to cooling, so holes should be provided in the cold insulator pieces that come into contact with the ear wings. It may be possible to avoid contact with this area, but since the position and size of the ear flaps vary from person to person, it is recommended to place several pieces of gauze or absorbent cotton in the ear flaps. It seems safer to apply them one after the other. The cold insulator piece for the back of the head is also made as long as possible so that it can cover the entire back of the head.

When the main body of the cooling device according to the present invention is worn, it is tightly attached to the skull using two elastic belts.

Both of these two elastic belts are made by joining elastic cloth onto sponge or felt.
It has a structure in which locking tools are provided at both ends, and is used with a sponge or felt surface as the inner surface. As a result, it closely engages with the net-like bag that is the main body of the cold insulator and does not slip against each other, thereby preventing it from falling off or slipping. The aforementioned fastening device is preferably the surface-adhesive type fastener described above, but other known fasteners such as buckles, hooks, and snaps can be used as desired. One of the above two elastic belts is for tying each cold insulator piece around the skull in a headband shape from the forehead to the back of the head,
The other one is used from the top of the head to the chin in order to bring the cold insulator piece for the top of the head into close contact with the top of the head.

The proposed head cooler is mainly composed of two coolers as described above.
In addition to being attached with a book's elastic belt, an insulating cap is placed over the outer surface of the main body of the cold storage device in order to further enhance the cold storage effect. The insulating cap is lightweight, flexible, and durable, prevents cold air from escaping as much as possible, blocks outside air, is shaped like an integrated hat that can cover the entire skull, and is prevented from falling off by a chin belt. Further, a portion of a band-shaped size-adjusting band is sewn onto the outer periphery of the truncated conical portion of the heat-insulating cap. Then, by adjusting the engagement position of the locking member attached to the free end of the dimension adjustment band to the locking portion provided on the outer periphery of the truncated conical portion of the heat insulating cap, the inside of the truncated conical portion can be adjusted. The size can be adjusted to fit the patient's head circumference. The above-mentioned heat-insulating cap has an inner surface made of a plastic foam sheet (approximately 1 mm thick) made of polyethylene, polystyrene, polyurethane, etc.
A plastic sheet composite having an aluminum vapor-deposited film on the outer surface is bonded to the plastic sheet composite, or one reinforced by interposing a mesh of thread between the plastic sheet and the aluminum vapor-deposited film. A layer coated with a mixture of urethane and acrylic is provided on the outer surface of the 100% nylon taffeta layer. It is constructed by laminating plastic foam sheets such as polyethylene, polystyrene, polyurethane, etc., and then applying a covering cloth layer such as nylon to the inner surface of the foam sheet layer.

Hereinafter, the present invention will be explained with reference to the embodiments shown in the drawings.

FIG. 1 is a developed plan view of the main body A of the cold storage device of the present invention, in which 1 is a mesh bag for the parietal region, 2 and 3 are mesh bags for the forehead, 4 and 5 are mesh bags for the temporal region, Reference numerals 6 and 7 denote mesh bags for the back of the head, and in each mesh bag, unit cold insulator pieces 1a to 7a each consisting of a plastic film bag b filled with an ice pack a are inserted and removed from the entrances and exits 1b to 7b, respectively. It has been inserted as possible. Although the mesh bag 1 for the top of the head is shown as having a hexagonal shape in FIG. 1, it may be circular or any polygonal shape. Further, the length of the mesh bags for the forehead 2 and 3 is shorter than the mesh bags for the temporal region 4 and 5 and the mesh bags for the occipital region 6 and 7, and extends to above the eyes. The mesh bag 1 for the top of the head and the surrounding mesh bags 2 to 7 are sewn together as shown in FIG. And entrance/exit 1b~ formed in each mesh bag 1~7
Although 7b may be formed at any arbitrary position, the position shown in FIG. 1 is preferable in order to facilitate the insertion and removal of each of the unit cold insulator pieces 1a to 7a and to prevent them from falling off. Moreover, it seems better for each of the entrances and exits 1b to 7b to have their mouth edges overlapped to some extent as shown in FIG.
Each of the unit cold insulating body pieces 1a to 7a inserted into each of the net bags 1 to 7 has the same shape or a similar shape to the shape of each net bag, and the surrounding pieces are approximately rectangular or rectangular. However, depending on the situation, it may be shaped like a fan or barrel.

Figure 3 shows the elastic belt B ₁ used in this invention.
It is a perspective view of B ₂ , in which the inside is made of sponge or felt fabric 8 and the outside is made of a suitable stretchable fabric 9, and both are integrally joined so that the whole has elasticity, and at both ends. Male and female fasteners 10 and 11 of surface adhesive type fasteners are attached.

Figures 4 and 5 show a heat insulating cap C used in the present invention, in which the upper part from the lower edge of the frontal part 12 is approximately a truncated conical part 13, and the part below it has a constricted rear lower end. A skirt-like part 14 that extends from both sides of the cheeks and covers the back of the head is formed, and the face part 15 has a notched helmet-shaped hat shape, and at the bottom of both sides of the face part 15, there are male and female hooks with surface-adhesive fasteners attached to the ends. Chin belts 18, 19 to which implements 16, 17 are attached, respectively, are integrally formed below the skirts 14, 14. 20 is insulation cap C
This is a dimension adjustment band attached to the forehead part 12 of the truncated conical part 13 in order to adjust the inner diameter of the truncated conical part 13. As shown in FIG. 5, the size adjustment band 20 has its center portion sewn to the forehead portion 12 of the truncated conical portion 13 of the heat insulating cap.
Furthermore, slightly longer surface-adhesive fasteners 23, 24 are attached to both ends 20a, 20b, which engage with surface-adhesive fasteners 21, 22 attached to both sides of the truncated conical portion 13 of the heat insulating cap. be. Then, determine the engagement position of the surface-adhesive fasteners 23 and 24 attached to both ends of the dimension adjustment band 20 to the surface-adhesive fasteners 21 and 22 attached to both sides of the truncated conical portion 13 of the heat-insulating cap. By adjusting and narrowing the frontal portion 12 of the heat insulating cap C, the diameter of the frusto-conical part 13 of the heat insulating cap can be adjusted.

The position where the dimension adjustment band 20 is sewn onto the heat insulating cap C is not limited to the frontal portion 12 of the heat insulating cap C, as described above, but can also be attached to the heat insulating cap C.
It can be on the side of the head or on the back of the head.

As mentioned above, the material constituting the heat insulating cap C is a foamed sheet on the inside and a suitably colored outer cover (having ventilation blocking properties) on the outside. And overall flexibility.

Next, the procedure for wearing the head cooling device of the present invention will be explained. The pre-cooled cold pack main body A is placed on the wearer's head with the front and back directions determined, and first, the peripheral area is tightened with a peripheral elastic belt B ₁ in the manner of a headband as shown in Fig. 6. At this time, apply gauze or absorbent cotton to an appropriate thickness on the wings of the ear. In addition, to suit the size, length, hairstyle, etc. of the wearer's skull, it can be rolled up and down, pulled up and down, or pulled back and forth and left and right to cover the entire skull evenly. Do it like this. Then, use the upper and lower elastic belt _B2 to firmly tighten the top of the head to the chin. As a result, the cold insulator piece at the top of the head is brought into close contact with the top of the head, and the surrounding cold insulator pieces are also brought into close contact with the periphery of the skull and fixed. Next, as shown in FIG. 7, the outer periphery of the main body A of the cold storage device is covered with an insulating cap C, and the truncated conical insulating cap of the surface-adhesive fasteners 23 and 24 attached to the ends of the size adjustment band 20 is The frusto-conical part 13 of the heat insulating cap C is adjusted by adjusting the engagement position with the surface-adhesive fasteners 21 and 22 attached to both sides of the heat insulating cap C and squeezing the frontal part 12 of the heat insulating cap C.
is brought into close contact with the main body A of the cold storage device. Finally, the locking tool 1 attached to the chin belt 18 on one side of the insulating cap C
6 is engaged with the locking tool 17 attached to the other chin belt 19, thereby bringing the heat insulating cap C into closer contact with the main body A of the cold storage device, and at the same time preventing the heat insulating cap C from falling off from the head. , finish wearing the head cooler. In this way, by tightening the size adjustment band 20 and the chin belts 18 and 19, the heat insulating cap C can be brought into close contact with the main body A of the cold pack. Of course, this will prevent cold air from escaping, block outside air, and enhance the cold insulation effect. Also, the truncated conical part 1 of the heat insulating cap C
3 is a size adjustment band 20 sewn on its outer periphery.
Due to this effect, it is possible to reliably fit the wearer's cranium in close contact with the wearer's head regardless of the size of the wearer's head circumference. Therefore, it is possible to prevent the heat insulating cap C from shifting when the wearer turns over or walks.

In addition, although the above example was explained as being used to prevent side effects caused by a certain type of drug,
The present invention can of course be used to cool the heads of patients with general fever.

As explained above, the head cooling device of the present invention has a shape in which the main body of the cooling device is composed of the top of the head and the peripheral portions arranged and connected in a radial manner. can be absorbed and adapted to all humans. In addition, each unit cold insulator piece has appropriate flexibility even when subjected to strong cooling, so that it can easily follow the shape of the skull. Furthermore, since each unit cold insulator piece is inserted into the mesh bag, condensed water droplets do not pass through the mesh due to their surface tension, and are prevented from adhering to the hair or scalp or dripping and wetting clothes. Does not cause pleasure. In addition, the main body of the cold pack can be folded into a small size and placed in a freezer/refrigerator. The main body of this cooler is tightened and fixed to the wearer's entire skull using two elastic belts, one for the periphery and one for the top and bottom, which improves the cooling effect and prevents it from falling off the head. Of course, it especially prevents shifting movement. Furthermore, the heat insulating cap maintains the cooling effect of the cold insulator pieces for a long time, and by tightening the size adjustment band and chin belt, each unit cold insulator piece is brought into closer contact with the skull. It has a hat-like shape and hides the main body of the internal cooling device in a fashionable manner, does not make the wearer feel uncomfortable, prevents the internal cooling body pieces from shifting when sleeping, especially when turning over, etc., and can remain in the worn state. It has the advantage of being able to move freely.
