Description

  The present invention relates to a container for housing a jaw-relaxation prevention device that reliably prevents mouth opening due to relaxation of jaw muscles of a corpse by a simple operation, and a chin relaxation for a corpse comprising a combination unit of the jaw-relaxation prevention device and the container The present invention relates to a prevention device.

  In general, the first phenomenon that occurs immediately after human death is muscle relaxation. Regarding the jaw, the genioglossus muscle, the geniohyoid muscle, and the geniohyoid muscle are relaxed, the lower jaw is depressed, and as a result, the body's mouth is opened. “Postmortem stiffness” of human temporomandibular joints usually develops after 1-2 hours, begins to disappear after 30-40 hours, and muscles relax. However, from an aesthetic point of view, the jaws must be pushed upward so that the mouth does not open, and the mouth remains closed.

  Usually, in order to solve this problem, a bandage is used, or a headrest part and a belt-like body having a chin pad that can be slidably adjusted with respect to the belt-like body, and one end of the belt-like body is one side of the headrest part. A jaw loosening prevention device, which is detachably fixed to the side by a hook-and-loop fastener, a so-called jaw band (see Patent Document 1), and a front portion outer periphery of a neck portion below the jaw, and configured to grip the front portion outer periphery. A chin support portion having a substantially U-shaped arm portion, and a lower support portion that comes into contact with the chest or clavicle of the corpse, and an elastic flange projecting forward from the chin support portion to support the chin upward. It is generally performed to use a chin support device (trade name: Chin collar) (see Patent Document 2).

When the bandage or chin band is used, the bandage or chin band is applied to the lower part of the lower jaw of the body, stretched along both sides of the cheek, tied to each other at the top of the head, or fastened with a detachable hook-and-loop fastener. However, these treatment methods have the following drawbacks.
-These procedures are usually performed by the hands of employees, nurses, etc., but the work of the procedures is cumbersome and requires two employees or nurses to obtain satisfactory results.
-The bandage or chin band is loosened or detached.
-Relatives want to make the body a little aesthetically beautiful, but with this method, the cheek is wrapped with a bandage or chin band from the chin and the hair is pressed down. It's hard to say.

  The chin support device (trade name: Chin collar) has a substantially U-shaped arm part firmly fixed to the neck of the body, an elastic flange part is applied to the lower part of the lower jaw, and the lower jaw is supported upward by the elastic flange. Because it is a thing, the support part of the neck and mandible is congested and becomes black. It is hard to say that it is an aesthetically pleasing method when a relative sees a blackened aza or a state where the neck is tightened with a substantially U-shaped arm.

In addition, as another method for preventing jaw relaxation, an inner fixing member connected to the jaw relaxation prevention tool so as to straddle the central incisor, side incisor, upper and lower dentitions or gums of the canine, It is sandwiched between the outer fixing members and adhered to the upper and lower teeth or gums with the adhesive material layer provided on the outer surface of the inner fixing member and the inner surface of the outer fixing member, or fixed by the ratchet mechanism of the connecting member. Has been proposed (see Patent Document 3).
However, since the upper and lower dentitions or gums of humans usually do not overlap, it is very difficult to fix the upper and lower dentitions in this way. Moreover, since it fixes with the dentition or gum of the front part of a mouth of a dead body, a lip is not closed beautifully, the form of a dead body worsens, and there exists a problem from an aesthetic viewpoint. In addition, the treatment is complicated and it is difficult to put it in the body's mouth.

  Further, the above-described jaw relaxation prevention device is easily noticeable and impairs the dignity of the corpse, so that it is usually removed when the corpse is stored. However, the corpse remains rigid after death, and muscle relaxation occurs again after one or two days, so it opens again on the funeral day, and the treatment with the above instruments is useless. There are many.

The upper and lower dentitions are bonded with an agent to prevent opening due to relaxation of the jaw.

  In accommodating the above-mentioned chin sag prevention device in the container, the bifurcated bifurcated portion of the chin relaxation preventing device is sandwiched between the lid portion of the bifurcated bifurcated portion accommodation space of the lid of the container and the main body portion. The pair of plate-like portions of the jaw relaxation prevention tool are accommodated so as to have a gap between the lid portion of the plate-like portion accommodation space of the lid portion of the container. In order to stably house the cadaveric loosening prevention tool for corpses in the container, the bifurcated branching of the chin resting prevention tool for corpses between the lid portion of the bifurcated branching portion accommodating space of the container lid and the main body portion For this purpose, various modes can be adopted. Preferably, the lower end portion of the bifurcated branch portion of the bifurcated joint member is placed on the main body portion of the container. A desirable mode is one in which a recess is formed and a groove for mounting the lower end portions of the left and right wall portions is formed. Thereby, at the time of incorporating the chin relaxation preventing apparatus for a corpse, the jaw relaxation preventing tool can be stably placed on the main body of the container. More preferably, a concave groove having a shape corresponding to the bifurcated branch portion of the bifurcated joint member is formed in the lid portion of the bifurcated branch portion accommodating space of the lid portion. Thereby, the bifurcated branch portion of the jaw relaxation prevention tool can be more stably sandwiched between the lid portion of the bifurcated branch portion accommodation space of the lid portion of the container and the main body portion.

  In addition, even if the release sheet is not further bonded to the adhesive layer on the upper and lower surfaces of the plate-like part, the chin relaxation prevention tool for the corpse does not adhere to the lid of the container. In order to be able to be accommodated in the container, the pair of plate-like portions of the jaw relaxation prevention tool should have a gap between the lid portion of the plate-like portion accommodating space of the lid portion of the container. is necessary. This eliminates the need for the release operation of the release paper when the release paper is further bonded to the adhesive layer on the upper and lower surfaces of the plate-like portion.

Each is formed. Note that an adhesive layer is applied and formed on the upper and lower surfaces of the plate-like portion 34 that come into contact with the molar teeth. However, for easy understanding, the adhesive layer is shown in FIGS. 3 and 4. Is omitted. The bifurcated bifurcated portion (connecting portion) 33 has a recessed portion 36 formed at the center portion from a slightly curved central side wall portion 39 and left and right side wall portions 37 curved inwardly toward the central side wall portion 39. The central side wall portion 39 and the left and right side wall portions 37 forming the portion 36 are formed in a tapered shape slightly projecting forward from the bottom to the top, and three protrusions 38 are formed on the outer surfaces of the left and right side wall portions 37, respectively. Therefore, it is easy to hold it with fingers.

  Therefore, it is easy to hold the jaw relaxation preventing device 30 by sandwiching a slightly curved portion inside the left and right side wall portions 9, 9 with fingers, and it is easy to push and bend so that the interval between the left and right wall portions 32 is slightly narrowed, Inserting and mounting the corpse into the mouth can be performed more easily. In addition, the plate-like portion 34 may be horizontal as shown in the figure, but in a curved shape in which the front and rear end portions are slightly warped so as to correspond to the top surface of the molar (molar and molar). It is preferred to fit closely to the top surface of the molars (molars and molars) when formed and mounted.

  As a material of the above-mentioned jaw relaxation preventing tool 30, a relatively elastic plastic or metal can be used. However, in countries where it is customary to cremate dead bodies, the metal remains unburned and is preferably made of plastic.

  In the use of the above-described chin relaxation preventing tool 30, for example, a pair of left and right joining members 31 are sandwiched between fingers, are bent so that the distance between the left and right wall portions 32 is slightly narrowed, and inserted into the mouth of the body. After the insertion, when the finger is released, the left and right wall portions 32 expand due to the elasticity of the bifurcated branch portion 33 bent in a substantially U shape, and come back to the original state and come into contact with the inner side surface of the molar. Thereafter, by closing the relaxed jaw, the upper and lower molars are bonded and fixed by the adhesive layer 40 on the upper and lower surfaces of the plate-like portion 34 as shown in FIG. In the above-mentioned jaw relaxation prevention tool 30, since the through-hole 35 is formed in the plate-like portion 34, the viscosity provided on the upper surface of the plate-like portion 34 when inserted and meshed between upper and lower molars. The adhesive layer 40 and the adhesive layer 40 provided on the lower surface are integrated through the through hole 35. Therefore, the upper and lower molars can be bonded and fixed with a strong bonding strength, and the opening of the mouth due to the relaxation of the jaw can be more reliably prevented.

  As mentioned above, although the suitable aspect of the chin relaxation prevention apparatus for corpses of this invention was demonstrated, this invention is not limited to an above described aspect, Arbitrary design changes are possible. For example, in the above-described embodiment, the left and right wall portions (inner lower wall portions) are formed so as to hang substantially perpendicularly to the inner edge portions of the pair of plate-like portions. It is also possible to form an inner upper wall portion that is erected substantially vertically upward. Alternatively, it further includes an outer upper wall portion that is erected upward substantially perpendicularly to an outer edge portion of the plate-like portion and / or an outer lower wall portion that is formed to hang downward, on both sides of these plate-like portions. The inner lower wall portion and the outer lower wall portion are configured to straddle the lower jaw dentition, and / or the inner upper wall portion and the outer upper wall portion on both sides of the plate-shaped portion are configured to straddle the upper jaw dentition. You can also.

  As the adhesive layer, various conventionally known adhesives, in particular, an ointment-type adhesive can be used, and the adhesive layer is not limited to a specific adhesive. Examples of the ointment-type adhesive include alcohol-based organic solvents (A) such as monohydric alcohols and polyhydric alcohols having a carbon number of 5 or more that are liquid at room temperature, carboxyvinyl polymers, and carboxyvinyl polymers. Acrylic acid polymers such as alkali salts or cross-linked acrylic acid polymers, polyethyleneimine, polyvinylpyrrolidone, polyvinyl methyl ether, polyethylene oxide, polyalkylene oxide-based thermoplastic nonionic water-absorbing resins, synthetic lipophilic smectites, starches Sugar [D. E. A viscous liquid base containing at least one thickener (B) such as (dextrose equiv. Is 50% or less)], and fibers such as plastic fiber, glass fiber, silk fiber, pulp fiber, cotton, sepiolite, etc. An ointment-type adhesive containing at least one filler (C) such as clay mineral can be suitably used.

  As the alcohol-based organic solvent (A), any alcohol solvent having 5 or more carbon atoms that is liquid at room temperature can be used and is not limited to a specific one. For example, monohydric alcohols include amyl alcohol, hexyl alcohol, Examples include green leaf alcohol, heptyl alcohol, octyl alcohol, nonyl alcohol, decyl alcohol, benzyl alcohol and the like. Examples of the polyhydric alcohols include ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, glycerin, polyethylene glycol (average molecular weight of polymerization degree is 500 or less) and the like. These alcohol-based organic solvents (A) can be used alone or in combination of two or more.

  The content of the alcoholic organic solvent (A) is preferably about 20 to 90% by mass, more preferably 25 to 85% by mass, and further preferably 30 to 80% by mass of the total amount of the ointment-type adhesive. If the content of the alcoholic organic solvent (A) exceeds 90% by mass, the ointment-type adhesive becomes soft and can firmly adhere and fix the upper and lower jaw teeth or gums. Since it disappears, it is not preferable. On the other hand, if the content of the alcohol-based organic solvent is too low, the ointment-type adhesive becomes hard and the adhesive strength is lowered, which is not preferable.

  The content of the thickener (B) is preferably about 10 to 80% by mass, more preferably 12 to 70% by mass, based on the total amount of the ointment-type adhesive. When the content of the thickener (B) exceeds 80% by mass, the ointment-type adhesive is hardened, the flexibility is lowered, the adhesive force is deteriorated, and the use is hindered. . Further, it is not preferable from the viewpoint of economy. On the other hand, if the content of the thickener (B) is too low, the ointment-type adhesive becomes soft, the adhesive force is lowered, and it becomes impossible to firmly adhere and fix the upper and lower jaw teeth or gums. Therefore, it is not preferable.

  The alkali salt of the carboxyvinyl polymer as the thickener (B) is obtained by neutralizing the carboxyvinyl polymer with an alkaline substance, and the viscosity is remarkably increased by neutralization. Examples of the alkali neutralizer include diethanolamine, triethanolamine, diisopropanolamine, di-2 (ethylhexyl) amine, amines such as triamylamine, dodecylamine, morpholine, sodium hydroxide, potassium hydroxide, water Examples thereof include inorganic salts such as ammonium oxide, aqueous ammonia, and the like. Among them, amines are preferable because they are easy to handle.

  The content of the filler (C) is preferably 0 to 50% by mass, more preferably 1 to 35% by mass, based on the total amount of the ointment-type adhesive. When the filler (C) content exceeds 50% by mass, the ointment-type adhesive becomes hard, the flexibility is lowered, the adhesive force is deteriorated, and the upper or lower jaw dentition or gum This is not preferable because it causes problems such as poor adhesion and opening of the mouth. On the other hand, if the filler (C) is not contained or its content is too low, the ointment-type adhesive becomes soft and the adhesive strength is lowered, and the upper and lower jaw teeth or gums are firmly adhered and fixed. This is not preferable because it becomes difficult to do this.

Furthermore, in order to maintain the said ointment-type adhesive agent stably, at least 1 sort (s), such as antioxidant (D) and antifungal and antiseptic | preservative (E), can be contained as a stabilizer.
As the antioxidant (D), various conventionally known antioxidants can be used, and are not limited to specific ones. Among them, α-tocopherol, nordihydroguaiaretic acid (NDGA), Examples thereof include butylhydroxyanisole (BHA), dibutylhydroxytoluene (BHT), gallic acid ester, isopropyl citrate, sodium L-ascorbate, L-ascorbic acid, isoascorbic acid and the like. These can be used alone or in combination of two or more.

  Examples of the fungicide / preservative (E) include sodium benzoate, sodium paraoxybenzoate, butyl paraoxybenzoate, propyl paraoxybenzoate, isobutyl paraoxybenzoate, sodium propionate, thiabendazole, and isothiazolone. These can be used alone or in combination of two or more.

  The content of the antioxidant (D) and the fungicide / preservative (E) maintains the desired effect of each component, and occupies the whole ointment-type adhesive from the viewpoint of safety and good economic efficiency. In proportion, the antioxidant (D) and the fungicide / preservative (E) are each preferably about 0.001 to 10% by mass, more preferably about 0.005 to 8% by mass.

Hereinafter, the present invention will be described more specifically with reference to prescription examples and test examples of an ointment type adhesive, but the present invention is not limited thereto.
Examples of ointment-type adhesives:
In the mixing ratio shown in Table 1, the antioxidant (dibutylhydroxytoluene) (D) is dissolved in the alcohol-based organic solvent (propylene glycol) (A), and further the thickener (carboxyvinyl polymer) (B) is dissolved. A viscous liquid base was prepared. A filler (glass fiber) (C) was added to this viscous liquid base and stirred well to prepare an ointment-type adhesive.

Test example:
A mortuary jaw relaxation prevention tool was prepared in which the ointment-type adhesive agent prepared as described above was fixed to the upper and lower surfaces of the plate-like portion shown in FIG.
When the obtained cadaveric loosening prevention tool for a corpse was attached to a replica occlusion model (made by Nissin Co., Ltd.) having a dentition, gums and temporomandibular joint as a substitute for a corpse, The jaws could be bonded and fixed together.
