Description

[Detailed description of the invention] The present invention is a cap-shaped cold storage device that can cover the patient's skull in a cap-like manner. This invention relates to a cold storage device that can be worn over the body.

Some drugs have a side effect that causes hair loss in patients receiving the drug.

Although this side effect can be prevented by forcibly cooling the skull during the medication period, the cold storage devices on the market today are column-shaped or bag-shaped, such as water pillows and ice packs. Even with cold packs containing organic cold packs, which are being used in place of water pillows and ice packs, they are plate-shaped or band-shaped at most, so it is difficult to use them to cover the entire circumference of a patient's skull. Very difficult.

Furthermore, even in cases other than preventing side effects caused by drugs, it is still preferable to cool the entire cranium in order to ease the pain of a patient with a high fever or to alleviate the symptoms.

However, until now there has been no cold storage device that can be used for this purpose.

The present invention seeks to meet the problem of providing a convenient means for keeping the entire cranium cool.

The essence of the present invention is that the cold insulator that runs over the cranium in a cap-like manner is divided into a plurality of flap-like unit pieces, and each unit piece is connected centripetally and movably at one end of each unit.

Specifically, this concept is realized through the following two types.

(1) A method of movably connecting a plurality of unit cold insulating body pieces radially around a cold insulating body piece that covers the top of the head.

(II) A method in which petal-shaped unit cold insulator pieces are arranged radially and movably connected at their sharp points.

In the first type, a cold insulator piece that covers the top of the head is formed into a circular, quasi-circular, or polygonal shape, and a plurality of cold insulator pieces are attached radially around the cold insulator piece.

The easiest method for attachment is to use the web portions around each unit cold insulator piece and weld the web portions together.

Each unit piece should be composed of at least four unit pieces, one for the frontal region, one for the left and right temporal regions, and one for the occipital region. It is preferable that each of the unit pieces for the head part and the occipital part be divided into about two pieces.

The lower edge of the frontal cooler piece generally does not reach below the eyebrow line of the person or at least below the eyes.

The temporal segment is the superficial temporal artery (which branches off from the carotid artery and ascends).
It is preferably long enough to cover the lower cheeks, as cooling of the temporal arteries is particularly effective in preventing hair loss.

However, in this case, the cooling piece will cover the ear fins, but since the ear fins are susceptible to frostbite due to cooling, holes are drilled in the cooling piece attached to the ear fins to cover the ear fins. It is preferable to avoid contact with the parts.

The cold insulator piece for the back of the head should also be made as long as possible so that it can cover the entire back of the head.

Each of the above pieces can be made into a cap shape by abutting opposite side edges and fastening with tape, or by connecting the opposite side edges with a fastening means such as a zipper hook, button, snap or surface-adhesive fastener. Complete the cold insulator.

If desired, a string or band may be attached to the outer end of the temporal region cold insulator piece and used as a neck strap, allowing the cold insulator to be more completely attached.

In type 1I, each unit cold insulator piece is shaped like a petal and joined together at their sharp points.

Incidentally, the term "pilot valve shape" here refers to a contour formed by two symmetrical positive curved arcs and a straight line connecting points equidistant from the intersection of the arcs, or something similar.

In this case, when the opposing side edges of each unit piece are joined together, a cap-like body similar to a tulip cap is formed, so there is no need to provide a cold insulator piece for the top of the head as in the previous type.

The cold insulating material used in the cold insulating body of the present invention may be exactly the same as that of conventional cold insulating bodies.

That is, a W10 type emulsion in which a hydrophilic hydrogel is encapsulated in a synthetic polymer material with little change in plasticity due to temperature is used. Machine oil and styrene
The material, which is formed by pouring a W10 type emulsion obtained by emulsifying butadiene-styrene teleblock elastomer with water in the presence of an emulsifier, into a hot mold does not lose its softness even when cooled in a freezing room. Therefore, it is suitable for devising purposes.

These materials are formed into a suitable shape, placed inside a flexible sheet of polyethylene, polyvinyl chloride, etc., and then heat-welded around the sheet to form a unit cold insulator piece.

However, since the cold storage device of the present invention is intended to cover the head, it is preferable that it be formed thinly, with a thickness of 1 cm or less, even if it sacrifices some heat capacity.

In addition, it is preferable that the interval between each cold insulator is a certain amount of leeway so that it can correspond to the shape, size, etc. of each individual's head.

Hereinafter, embodiments of the invention will be specifically described using drawings, but these are merely examples and are not directly related to the technical scope of the invention.

FIG. 1 is a plan view (developed view) showing an example of a device belonging to type (2).

The entire cold pack 1 consists of cold pack pieces 1 b and 1 b' for the top of the head.
, a pair of left and right temporal head cold insulator pieces 1c, lc' and two pieces 1
It is made from a total of seven unit pieces, including a set of cold insulator pieces 1d and 1d' for the back of the head.

The cold insulator piece for the top of the head has a substantially regular hexagonal shape, and web portions 2 b , 2 b', 2 C, 2 C' on each side thereof.
, 2d and 2d', corresponding webs 3b, 3b', 3C, 3C', 3d and 3d of the trapezoidally shaped cold insulator pieces for the frontal region, the temporal region and the occipital region, respectively. ' are welded to each other (see Figure 2A).

Note that ear holes 4, 4' are bored in the ear wing contact portions of the left and right temporal head cold insulator pieces 1c, 1c'.

The above-mentioned cold storage device 1 is cooled in advance in an expanded state in a freezer compartment, and then
Fold the top of head cold insulator piece 1a along the joint 5 of each other cold insulator piece and place it over the head of the patient P (Fig. 3A,
(see B), tape the opposing side edges of each cold insulator piece with adhesive tape 6.
(See also Figure 2B).

As a result, the patient's head, excluding the face and jaw area, including the most important superficial temporal artery area (temple area), is completely covered by the ice pack along the curved surface of the head. Therefore, not only hair loss can be effectively prevented, but also there is no fear that the ear wings will suffer from frostbite.

In addition, it is comfortable for patients to wear, and there is no risk of it falling off during use.

Moreover, since it is easy to attach and detach from the head and does not take up much space during cooling and storage, it is easy to handle in hospitals, homes, etc.

Note that if the entire attached cold storage device is further covered with a heat insulating sheet such as urethane foam, the cold storage effect will be even better, and the time until replacement will be greatly extended.

FIG. 4 shows a specific example of a device belonging to type II.

In this example, all the cold insulator pieces are 1b for the forehead and 1b for the left and right sides of the head.
It consists of four sheets: c, lc', and 1d for the back of the head.

The base pieces are petal-shaped and are bound together at the web portion of their sharp parts 7 (if necessary, cut the sheet that wraps the cold insulating material into a shape connected at the tips of each sharp part, and insert A petal-shaped unit cold insulation material may be wrapped.

). The usage, function, and effects of this cold pack are the same as those of the previous example, but in this case, since it is equipped with chin straps 9 and 9',
Compared to the previous example, the cold pack can be attached more securely.

FIG. 5 shows an example in which surface-adhesive fasteners (for example, those commercially available under the trade name ``Velcro Tape'') 8.8' are attached to the front and back surfaces of the facing web in the example shown in FIG.

In this example, since the opposing webs can be easily joined using a fastener, attachment and detachment operations are easier.

Of course, the present fastener may be replaced by equivalent means such as buttons, hooks, snaps, line-adhesive fasteners (common fasteners), etc.

The above description has been given of the cold pack as a means to prevent hair loss caused by side effects of drugs, but the cold pack of the present invention can of course also be used to cool the heads of ordinary fever patients.

In this case, since forced cooling of the superficial temporal artery is generally not necessary, it is sufficient that the temporal region cooling body piece has a length that reaches the upper edge of the ear wing.

As detailed above, the present invention can be used as a head cooler because it is easy to put on and take off, and because it fits the head and does not come off when worn, it provides effective cold insulation. This completely solves the above-mentioned problems, such as requiring no time or space for storage.
