Description

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

Some drugs that have been developed in recent years can cause hair loss in patients as a side effect, but their continued administration is often desired due to their outstanding medicinal efficacy. .

Therefore, various methods are being researched to reduce the above side effects as much as possible.Recently, a clinical case has been reported showing that the above side effects can be prevented by forcibly cooling the patient's skull during the medication period. has been done.

However, the cold packs on the market today are pillow-shaped or hanging types, such as water pillows and ice packs.
It can only cool the skull locally and can only be used when the patient is lying down.

Furthermore, even if a cold pack is made by filling a plastic sheet bag with a chemical substance such as organic cold packs, which have recently been used in place of water pillows and ice packs, it is at most headband-shaped, so it cannot be used locally. However, even if it is possible to cool the entire circumference of the patient's skull, it cannot provide a complete cooling effect sufficient to counteract the side effects of the drugs mentioned above. It had the disadvantage of falling out of the group.

Therefore, in response to requests from the nursing community, the present applicant has developed a head cooling device that can effectively keep the entire cranium cool and that does not cause pain to the patient even when used for a long period of time. It was proposed based on the invention of Mine No. 56-692 and Utility Application No. 56-62013.

To roughly explain the structure of these head cooling devices devised earlier, the cooling body pieces arranged in a radial manner or the covered pieces for storing the cold body pieces so as to be removable and removable are provided with surface-adhesive fasteners or other locking means. They are connected to each other so that their dimensions can be adjusted to form a cap shape.

Although this ice pack has already been used clinically and its usefulness has been recognized, the inventor of the present invention has carried out studies aimed at further improving the cold retention effect of this cold pack. This led us to come up with an idea.

Therefore, the purpose of the present invention is to provide a head cooling device that can keep the entire cranium cool even more effectively. A heat insulating cap is placed on the outer surface of the cap-shaped cooling body, in which the cover pieces, which accommodate the pieces in a removable manner, are connected to each other and are configured to cover the cranium in a crown-like manner.

The head cooling device of the present invention is configured to cover the entire operculum and is always attached to the cranium.

Furthermore, the proposed ice pack is strongly cooled in the freezer before being worn, so if the ice pack inside solidifies during cooling, it will not only be difficult to wear but also painful for the wearer. bring about.

Therefore, it is preferable that the ice pack used in the cold storage device of the present invention maintains its appropriate softness 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.
It is packaged in a synthetic polymer material in the form of a Type 10 emulsion with little change in plasticity due to temperature, but of course any other known cold pack that does not lose its appropriate softness even with strong cooling can be used. .

The above ice pack is enclosed in a bag made of a flexible sheet made of plastic such as polyethylene or polyvinyl chloride to form a unit cold pack piece.

This cooling device can cover the entire cooling device when worn, and is easy to fit as it matches the size of each person's cranium.On the other hand, it can be folded to the minimum volume when cooling in the freezing room. It is preferable that the structure is such that it can be used.

Therefore, according to a preferred embodiment of the present invention, a plurality of cold insulators are arranged around a polygonal or circular unit cold insulator piece that covers the top of the head, as shown in FIG. 2 or FIG. It is formed by attaching unit cold insulating body pieces radially, or by arranging petal-shaped unit cold insulating body pieces radially and connecting them to each other at the tip of each cold insulating body piece as shown in Fig. 5. Ru.

The simplest method for joining the unit cold insulator pieces together to form a hat shape is to utilize the web portions around each body piece and weld the web portions together.

However, in this case, it is necessary to make caps of several different sizes to match the different sizes of the patient's skull.

Therefore, size flexibility can be provided by attaching elastic cloth pieces between adjacent webs of each unit cold insulator piece.

In addition, in order to provide dimensional flexibility and simplify the installation process, the web portion of each unit cold insulator piece is commercially available under the name Velcro Fastener (registered trademark) or Magic Fastener (registered trademark). By attaching surface-adhesive fasteners, the cold insulator pieces can be connected to each other.

Other known fasteners such as slide fasteners, hooks, buttons or snaps can optionally be used in place of the above-mentioned fasteners (surface-adhesive type).

In the head cooling device configured as described above, the lower edge of the frontal cooling body piece generally does not reach below the eyebrow line of the person or at least below the eyes.

The temporal region cooler piece preferably has a length sufficient to cover the lower part of the cheek, since cooling of the superficial temporal artery, which branches from the carotid artery and ascends, is particularly effective in preventing head hair from falling off.

However, in this case, the temporal head cold insulator piece will cover the ear fins, but since the ear fins are susceptible to frostbite due to cooling, holes are punched in the cold insulation piece that comes into contact with the ear fins. It is preferable to avoid touching this part.

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.

According to another preferred embodiment of the present invention, a plastic with excellent low temperature properties is used instead of the structure in which a plurality of cold insulator pieces themselves are arranged radially and bonded to each other to form a cap shape as described above. A plurality of flexible materials such as a polyester film, a honeycomb woven fabric of polyester fibers, a cloth material or a plastic film laminated or vapor-deposited with aluminum foil are used to form a plurality of radially arranged polyester fibers as shown in FIGS. 2 and 5. The above-mentioned cold insulator pieces may be loaded into pockets provided on the inner surface of each of the covered pieces so that they can be taken in and taken out.

In this case as well, the adjacent peripheral edges of each covered piece may be connected to each other by any locking means such as surface-adhesive fasteners, but according to the present invention, as will be described in detail later, the cap-shaped cold insulator Furthermore, since the outer surface is covered with an insulating cap,
With emphasis on ease of installation, the strings inserted through the lower edges of the temporal and occipital cold insulation pieces are tightened under the chin as shown in Figure 6, so that they can be attached to the skull. It can be fixed in place.

According to the present invention, in order to further enhance the cooling effect of the cap-shaped cooling body configured as described above, an insulating cap is placed on the outer surface of the cooling body.

The heat insulating cap is formed into a cap shape using a flexible heat insulating material such as a plastic foam sheet such as polyethylene, polystyrene, or polyurethane, a cloth material laminated or vapor-deposited with aluminum foil, or a plastic film.

Further, the cap may be formed into a cap shape by arranging a plurality of unit covering pieces in a radial manner and connecting each unit piece so that they can be separated from each other, as in the case of the cap-shaped cooling body described above. In order to simplify the process of attaching the tool to the head,
It is preferable that the cap is integrally molded into a hat shape by a casting method or any processing method such as sewing or welding.
