DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel for preventing body fluid from leaking into a body cavity of a corpse, and a method for preventing body fluid from leaking using the gel.

[0002]

2. Description of the Related Art The human body may leak body fluids such as gastric juice, lung fluid, ascites and excrement after death. For this reason, for example, in hospitals, after confirming death, the mouth, nose, ears, anus,
2. Description of the Related Art Gauze, cotton wool, and the like are loaded into a body cavity such as a woman's vagina to prevent leakage of body fluid. Similar measures are taken at the opening of the corpse after an accident or surgery.

It is known that a highly water-absorbent resin powder is loaded into the mouth, nose, ears, throat and the like in place of gauze, absorbent cotton and the like. For example, in Japanese Patent Application Laid-Open No. 7-26567, it is known that a water-absorbent resin powder containing stabilized chlorine dioxide is used as it is in the throat while being wrapped in a water-soluble sheet for the ear and nostrils. Also, as in Japanese Patent Application Laid-Open No. 10-298001, it is known that a mouth, a nose, and an ear are loaded with a superabsorbent resin powder using a syringe.

[0004]

According to the general method of loading gauze, cotton wool or the like into the body cavity such as the mouth, nose and ears of a corpse, if there are many leaked bodily fluids, gauze, cotton wool or the like is used. Inadequate and leaking out of the body.
When treating the leaked body fluid, there is a risk of infection with pathogenic bacteria,
Disliked by workers. In addition, it is necessary to replace with new gauze, absorbent cotton, or the like, which is not only troublesome, but also involves a risk of infecting with pathogenic bacteria through body fluids, and there is a problem that, at the time of replacement, a stench of the leaked body fluid remains around.

[0005] Even if the throat is to be loaded with the superabsorbent resin powder as disclosed in Japanese Patent Application Laid-Open No. Hei 7-265367, there is no means for loading the powder in a body cavity at a narrow interval such as the throat or anus. It is difficult.

Japanese Patent Application Laid-Open No. 10-298001 describes that a fine powder of a superabsorbent polymer is used in order to ensure fluidity as much as possible. However, if it is put in the entrance of the nostrils or ear canal, it can be filled even if the fine powder is injected with a cylinder like a syringe as in this publication,
It cannot be filled to the back. In particular, to fill to the back,
When the cylinder is moved rapidly, the fine powder coming out of the tip just scatters, but only contaminates around the body.

That is, in the method of filling powder into a body as it is, as disclosed in Japanese Patent Application Laid-Open Nos. Hei 7-26567 and Hei 10-298001, even if the powder is pressed, only the density of the powder itself increases. Since it does not flow smoothly through the inside, it is difficult to fill even if a cylinder is used.
In addition, since the popping powder is diffused, it is difficult to solidify the powder and keep the powder at a place where a plug is desired, and in some cases, the powder may go out of the body and stain the area around the body. Furthermore, when the powder is directly loaded into the body, there is a possibility that the fine powder may spill out or the gel may melt and leak to the body with little body fluid.

[0008] In particular, as a powder, various resin powders have been developed with an emphasis on absorbing body fluid and swelling. Both are hydrophilic resin powders, and this kind of resin powder has an excellent function of absorbing body fluid, swelling and gelling. However, this type of resin powder becomes a sol when the amount of absorption is large, and is often melted as it proceeds further. In addition, if the body fluid contains a strongly acidic body fluid such as gastric acid or an alkaline body fluid such as bile, the gel state cannot be maintained in many cases.

[0009] Since simply loading the resin powder into the body as it is does not work, in actual practice, emergency treatment is still performed only with gauze or absorbent cotton, and realization of a body fluid leakage prevention technology replacing gauze and absorbent cotton is strongly desired. ing.

A first object of the present invention is to develop a novel body fluid leakage preventive agent since the body fluid cannot be prevented from leaking by the conventional resin powder. In particular, it is characterized by the development of a resin capable of maintaining a gel state for a long period of time regardless of the amount of body fluid and sealing a body cavity.

A second object of the present invention is to seal a body cavity by using a resin gel that can maintain a gel state even when an alkaline or acidic body fluid or the like is contained and can seal the body cavity. Features. In particular, a feature of the present invention is a method in which a resin having both hydrophilicity and hydrophobicity (or lipophilicity), that is, an amphiphilic gel is loaded into a body cavity as a body fluid sealing agent, and the body cavity is sealed.

[0012]

In order to achieve the above object, the invention according to claim 1 is characterized in that the body fluid leakage preventive loaded in the body cavity of the corpse is made of an amphiphilic gel, so that gastric acid or stomach acid is contained in the body fluid. Even if an acidic or alkaline liquid such as bile is contained, the gel state can be maintained without melting. Further, when the amphiphilic gel absorbs liquid to a certain point and swells, it becomes more difficult to absorb the liquid, and the gel strength is strong, so that it plays a sufficient role as a sealing stopper.

According to a second aspect of the present invention, since the amphiphilic gel is mainly composed of dimethylacrylamide, the amphiphilic gel is nonionic and has a higher P-absorbency than a highly absorbent gel.

It is more stable to PH than a superabsorbent gel, and can maintain the gel state without dissolving even if the body fluid contains an acidic or alkaline liquid such as gastric acid or bile.
Further, when the amphiphilic gel absorbs liquid to a certain point and swells, it becomes more difficult to absorb the liquid, and the gel strength is strong, so that it plays a sufficient role as a sealing stopper.

Although the present invention has been described in the embodiment in which the throat is introduced through the nostrils, the present invention may be applied to the oral cavity of the body, the nares itself, the ear canal, the urethra, the anus, and the female vagina. Further, the present invention may be applied to a wound or an opening of a corpse after an accident or an operation.

Although not shown, a body fluid leakage preventive made of an amphiphilic gel is prepared by being wrapped in a water-soluble film, or the body fluid leak preventive made of an amphiphilic gel is swelled from the tip in a smooth shape. Thereafter, it may be formed in a capsule shape having a small diameter smoothly toward the rear, and a lubricant may be applied to the surface of the capsule. In order to enhance the shape holding function, a stretchable net may be covered, and a lubricant may be applied thereon, or a stretchable net containing a lubricant may be covered. In particular, the anus and the female vagina / urethra can be loaded with the sensation of inserting a suppository, and the work is relatively easy.

[0068]

According to the present invention, the amphiphilic gel is a bodily fluid leakage preventive composed of an amphiphilic gel, especially the amphiphilic gel containing dimethylacrylamide as a main component. Therefore, the amphiphilic gel is nonionic and has high absorption. It is more stable to PH than a sexual gel, and can maintain a gel state without dissolving even if the body fluid contains an acidic or alkaline liquid such as stomach acid or bile. Further, when the amphiphilic gel absorbs liquid to a certain point and swells, it becomes more difficult to absorb the liquid, and the gel strength is strong, so that it plays a sufficient role as a sealing stopper.

The method for preventing body fluid leakage using an injector or a pressure accumulator can introduce and stop the amphiphilic gel at a predetermined position in the body cavity without scattering.
