Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jaw loosening prevention device for a corpse, and more particularly, to a mortal body which is used by being inserted into the mouth of the corpse to prevent opening of the mouth due to relaxation of jaw muscles. The present invention relates to a jaw loosening prevention device.

[0002]

2. Description of the Related Art When a person dies, stiffness starts due to coagulation of muscle protein, and when the person is completely stiff, it is no longer possible to move joints. Usually, post-mortem stiffness starts at the upper joints such as the jaw and neck muscles, and then moves to the upper and lower limb joints. Muscles relax once after death, but rigidity is 1 after death
Begins after ~ 3 hours and spreads throughout the body in 6-7 hours.

Therefore, if the corpse is left in a natural state lying on its back, the mouth is opened due to the weight of the body. If the body is rigid, it is difficult to close the mouth.
If the body's mouth is left open, the dignity of the body will be impaired and the family members will be uncomfortable, so measures are usually taken to close the mouth just before hardening.

[0004] Various methods have been conventionally proposed in order to take measures to close the mouth just before hardening as described above.
For example, Japanese Patent Publication No. 5-83260 and Japanese Patent Laid-Open No. 7-21
Japanese Patent No. 3568 discloses a pillow for the dead. In this pillow for the dead, one or two detachable pillows are provided on the side of the pillow body.
A column of books is provided. Place the head of the corpse on the pillow body, and use the detachable strut located next to the head,
Stretch a string-shaped jaw tension member. By hanging the tension member on the tip of the chin, the mouth is kept closed.

On the other hand, JP-A-8-71112 discloses that
A jaw loosening prevention device for a dead person is disclosed, which comprises a band-shaped body having a hat-shaped headrest and a slide-adjustable chin pad. In the case of using this preventive device, a head support is placed on the head of the corpse, and a band with a chin pad having one end connected to one side of the head support is provided on the other side of the head support via the jaw. Fix it detachably. In this way, the mouth of the corpse is fixed in a closed state.

[0006] All of the above-mentioned prior art devices for closing the mouth of a corpse have been devised for the purpose of holding the jaw closed until stiffness is completed after death. When caskets are to be stored in the body, the jaw-relaxation devices are usually removed because they are more visible and impair the dignity of the body.

[0007] However, once stiffness occurs after death,
Rather than staying stiff, one to five to six days later, muscle protein relaxes as muscle protein degradation progresses. Therefore, depending on the corpse, the mouth is reopened on the day of the funeral, and the treatment with the above-mentioned instrument is often wasted.

[0008]

In order to simply prevent the mouth from opening, a plastic or hardening-reactive clay-like or paste-like joining material is applied to the upper and lower jaw teeth or gums to form the upper and lower jaws. A method of bonding and fixing, or a method of foaming and spraying various bonding materials dissolved in a low boiling point solvent into the mouth, filling gaps between upper and lower jaw dentitions or gums, and fixing upper and lower dentitions or gums. And so on.

[0009] However, in these methods, the dignity of the corpse is significantly impaired in order to impair the aesthetic appearance of the corpse. Furthermore, if it becomes necessary to remove the joining material, it takes a lot of trouble to return to the original state, and in some cases, the dead body may be damaged.

It is an object of the present invention to prevent the opening of a corpse with a simple operation without impairing the feelings of the deceased and maintaining the dignity of the corpse. It is an object of the present invention to provide a chin-relaxation preventing device for a corpse, which can be removed to the original state and can return the corpse to its original state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific embodiment of a jaw loosening prevention device for a corpse according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic cross-sectional view showing a use state of a jaw loosening prevention device for a corpse according to a first embodiment of the second invention of the present application, and FIG. 2 shows an appearance of the jaw relaxation preventing device. It is a perspective view.

As shown in FIG. 1, the jaw relaxation preventing device 1 for a corpse is inserted into the mouth 3 of the corpse 2, and the upper and lower jaws 4, 5 are integrally anchored and fixed to relax the jaw muscle. Acts to prevent the opening of the mouth.

As shown in FIGS. 2 and 3 (a) to 3 (c), the jaw relaxation prevention device 1 includes a first fixing member 6 disposed on the outer surface of upper and lower teeth or gums, and a first fixing member 6; And a second fixing member 7 disposed on the inner surface side of the upper and lower teeth rows or gums. First fixing member 6
Is configured to straddle the upper dentition or gum and the lower dentition or gum on the outer surface of the upper and lower dentition or gum. On the other hand, the second fixing member 7 is configured to straddle the upper dentition or gum and the lower dentition or gum on the inner surfaces of the upper and lower teeth or gums.

In FIG. 2, the first and second fixing members 6 and 7 are formed of substantially rectangular plate-like members having a curved surface in the lateral direction so as to straddle the upper and lower tooth rows or gums. .
The reason why the lateral directions of the first and second fixing members 6 and 7 are curved is to conform to the curved surface of a human dentition or gum. However, since the first and second fixing members do not necessarily need to extend over the entire length of the dentition or gum, the lateral dimensions of the first and second fixing members 6 and 7 are not particularly limited. If it is configured to be attached only to the central part of the rows or gums, it need not necessarily be curved in the lateral direction. Further, the second fixing member 7 may have a protruding portion along the palate of the upper jaw or the tongue of the lower jaw.

In the center of the first fixing member 6, a through hole 6a
Are formed. On the other hand, one connecting member 8 extends forward from the front center of the second fixing member 7. In the present embodiment, the second fixing member 7 and the connecting member 8 are integrally formed by integral molding of a synthetic resin. However, the connecting member 8 is prepared as a separate member, and one end thereof is the second fixing member. It may be fixed to the front center of the member 7 with an adhesive or the like. Further, two or more connecting members may be provided.

On the upper surface of the connecting member 8, a ratchet 8a is formed. The ratchet may be provided on the lower surface or both surfaces. The ratchet 8a has a plurality of protrusions 8b. The protrusion 8b is formed so as to reach both ends in the width direction of the connecting member 8. As shown in the side sectional view of FIG. 4, the projection 8b has a front inclined surface 8c and a rear substantially vertical surface 8d. The height of the projection 8b is equal to the through hole 6a.
, But is selected such that the vertical surface 8 d is locked to the front surface of the fixing member 6 around the through hole 6 a of the first fixing member 6. That is, when the first fixing member 6 is to be moved forward with respect to the second fixing member 7,
The height dimension of the through hole 6a and the height of the protrusion 8b of the ratchet 8a are selected so that the forward movement of the first fixing member 6 is locked by the vertical surface 8d.

Next, a method of using the jaw loosening prevention device 1 of the present embodiment will be described. As shown in FIG. 1, the jaw loosening prevention tool 1 is inserted into the mouth of the corpse from the second fixing member 7 side. Then, the second fixing member 7 is located at the back of the upper and lower teeth or the gums. On the other hand, the first fixing member 6 is located in front of the upper and lower dentitions or gums. In this case, the distance between the first and second fixing members 6 and 7 is set to be smaller than the distance between the inner surface and the outer surface of the upper and lower teeth or the gum in advance. Set to be larger.

Next, the distal end side of the connecting member 8 is held by the fingers, and the first fixing member 6 is slid backward by the other fingers. Insert the dentition or gums. In this case, the rear surface of the first fixing member 6 is in contact with the upper and lower tooth rows or the front surfaces of the gums, and the front surface of the second fixing member 7 is in contact with the upper and lower tooth rows or the inner surfaces of the gums. In this state, the first fixing member 6
Is pressed backward, and the projection 8 b of the connecting member 8 is inserted into the through hole 6.
a. That is, the vertical surface 8d is locked to the front surface of the first fixing member 6 at the periphery of the through hole 6a.

Thus, the upper dentition or gums of the body,
The lower dentition or gums are connected to the first and second fixing members 6,
7, the upper and lower jaws are moored and fixed integrally. Therefore, even if re-relaxation immediately after stiffness after death begins, opening of the mouth of the corpse can be prevented.

Although the materials forming the first and second fixing members 6 and 7 and the connecting member 8 are not particularly limited, the cost and the weight can be reduced by using a synthetic resin. In addition, when the connecting member 8 is long, the extra length portion in front of the connecting member 8 may be cut after the chin relaxation prevention device 1 is attached, and thereby the dignity of the corpse is not impaired. Therefore, preferably, the connecting member 8
Is made of a synthetic resin material that can be easily cut.

More preferably, the first fixing member 6
A viscoelastic layer or a foam layer is provided on the rear surface of the second fixing member 7 and the front surface of the second fixing member 7. By providing the viscoelastic layer or the foam layer, the first and second fixing members 6 and 7 are brought into close contact with the upper and lower dentitions and gums even if the dentition and gums have defects or irregularities. And the upper and lower jaws can be more securely moored and fixed. The viscoelastic layer is not particularly limited. For example, JIS K721
A material having a hardness A of 100 or less is preferably used.

Instead of the viscoelastic layer or the foam layer, an irregular pattern may be provided on the rear surface of the first fixing member 6 and on the front surface of the second fixing member 7. By providing the pattern, similarly, when there are irregularities or defects on the surface of the upper and lower teeth and the gums, the upper and lower jaws can be more securely fixed by the slip prevention effect due to the irregularities.

In the jaw loosening prevention device 1 of the first embodiment, the ratchet 8a is formed on the upper surface of the connecting member 8.
As shown in a plan sectional view in FIG. 5A, a plurality of projections 8e for forming a ratchet may be formed on a pair of side surfaces. In this case, as shown in FIG.
The through hole 6a provided in the fixing member 6 has a two-stage structure with different opening widths, and is configured so that the rear surfaces 8f of the plurality of projections 8e are locked on the narrow side of the through hole 6a. Good.

The connection of the first and second fixing members 6 and 7 by the connecting member 8 is not limited to the one using the ratchet. For example, as shown in a side sectional view in FIGS. 6A and 6B, a connecting member 18 made of a stretchable elastic material having a larger cross-sectional shape than the through-hole 6a may be used.
Here, since the connecting member 18 is made of a stretchable elastic material, the jaw relaxation preventing device is attached to the mouth, and after closing the mouth, the first fixing member 6 is pressed against the front of the dentition or the gum. Meanwhile, the connecting member 18 is pulled out of the mouth. As a result, the connecting member 18 expands and becomes thin, so that the through-hole 6a
And the first and second fixing members 6, 7
The distance between them is reduced, and the upper and lower rows of teeth or gums are sandwiched between the first and second fixing members 6 and 7. Thereafter, when the pulling force of the connecting member 18 is released, the connecting member 18 becomes thicker due to shrinkage. Therefore, as shown in FIG. 6B, the connecting member 18 is locked by the through hole 6a. As a result, the first and second
The upper and lower gums or dentition are sandwiched between the fixing members 6 and 7, and the state in which the upper and lower jaws are moored and fixed is maintained.

The first and second fixing members 6, 7 and the connecting members 8, 18 are preferably made of a material that can be incinerated. For example, it can be constituted by using an appropriate resin of thermoplasticity, thermosetting or chemical curability, or a viscoelastic elastomer or a foam thereof, or by appropriately combining these.

The method of manufacturing the first and second fixing members 6 and 7 and the connecting members 8 and 18 is not particularly limited. For example, when made of synthetic resin, known injection molding, insert molding, vacuum molding, and mold molding are used. Alternatively, press molding or the like can be used.

However, in order to increase the productivity,
The second fixing members 6, 7 and the connecting members 8, 18 are desirably made of a thermoplastic resin or a viscoelastic elastomer. Also, the workability of mounting on a corpse or the easiness of removal in case of an emergency is taken into consideration. Then, since it is desirable to have appropriate flexibility, olefin-based polymers such as polyethylene and polypropylene; acrylonitrile / butadiene / styrene-based copolymer or ethylene-vinyl acetate-based copolymer, olefin-α-olefin-based polymer Thermoplastic resins such as copolymers; furthermore, olefinic, styrenic,
Injection molding or insert molding of various thermoplastic elastomers rich in viscoelasticity, such as ester and urethane, is preferred.

FIGS. 7 (a) and 7 (b) are a plan view and a side view for explaining a jaw loosening prevention device according to another embodiment of the second invention of the present application. Jaw loosening prevention device 21 of the present embodiment
Is configured similarly to the jaw loosening prevention tool 1 of the first embodiment, except that a frame-shaped member 22 is provided on the rear surface of the second fixing member 7. Therefore, the same portions are denoted by the same reference numerals, and detailed description thereof will be omitted by using the description performed in the first embodiment.

On the rear surface of the second fixing member 7, a frame-shaped member 22
Are integrally formed. In the present embodiment, a through hole 7a is formed at the center of the second fixing member 7, and the connecting member 8 extends rearward through the through hole 7a.
An upper frame member 22a and a lower frame member 22b having a substantially rectangular planar shape are provided so as to extend rearward from above and below the second fixing member 7. Upper frame member 22a
The lower frame member 22b is connected to the connecting member 8 on the rear end side. Further, the upper frame member 22a and the lower frame member 22b are inclined so as to approach toward the rear.

The frame member 22 is formed integrally with the second fixing member 7, but may be formed as a separate member and bonded to the back surface of the second fixing member 7 by bonding or the like. Further, the frame-shaped member 22 includes first and second fixing members 6 and 6.
7 can be made of the same material.

Attachment may be performed in the same manner as the chin relaxation prevention device 1 of the first embodiment. However, in the present embodiment, the frame-shaped member 22 is inserted into the mouth. Therefore, when the connecting member 8 is pulled and the first fixing member 6 is moved toward the second fixing member 7 to sandwich the upper and lower teeth or gums, the frame-like member 2 is pulled out as the connecting member 8 is pulled out.
2 elastically deforms and swells up and down. Due to this elastic deformation,
A force for pulling the connecting member 8 backward is generated.

Therefore, when the connecting member 8 is locked to the first fixing member 6 using the ratchet of the connecting member 8, the first and second fixing members are elastically restored by the frame-like member 22. The force for urging the 6, 7 to approach each other acts. Therefore, the rear surface of the first fixing member 6 and the front surface of the second fixing member 7 can be strongly pressed against the front surface and the rear surface of the dentition or the gum, and the dentition by the first and second fixing members 6 and 7 can be obtained. Alternatively, the force for pinching the gums can be prevented from loosening over time. Therefore, according to the second embodiment, the upper and lower jaws can be more securely anchored and fixed together more securely than the jaw loosening prevention device of the first embodiment.

Preferably, an adhesive material layer is provided on the outer surfaces of the upper frame member 22a and the lower frame member 22b. In this case, since the outer surfaces of the upper frame member 22a and the lower frame member 22b adhere to the palate, the integral anchoring of the upper and lower jaws can be further enhanced.

The lateral direction is curved backward. The curvature is designed to correspond to the curvature of the upper and lower dentitions or the anterior surfaces of the gums. However, the jaw relaxation prevention device 31 does not necessarily need to be formed over the entire length of the upper and lower dentitions or gums. For example, it may be arranged only in the central part of the dentition or gums, in which case it is not necessary to provide a curved portion in the lateral direction.

As for the material and manufacturing method of the fixing member 32, the same material and manufacturing method as those of the first and second fixing members 6 and 7 in the second embodiment of the present invention can be used.

The adhesive layer 33 is configured to have a softness and a thickness that can follow irregularities on the surface of the teeth or gums. The material constituting the adhesive layer 33 is not particularly limited, and a material having slight tackiness, that is, a material having slight tackiness can be used.
For example, an appropriate anti-inflammatory analgesic cataplasm, total denture fixative, denatured cellulose, acrylic acid, maleic anhydride, vinyl acetate, etc., which is widely used in electrodes of electrocardiographs, or pressure-sensitive adhesive A conventionally well-known adhesive material such as an adhesive can be used. These adhesives are
