Description

  The present invention is a treatment of a corpse for preventing leakage of a body fluid by injecting a two-component foamed urethane composition into a body cavity such as the mouth, nose, ear, anus, or vagina of a woman and foaming and sealing the body. Relates to the device.

  In general, after death of a human or animal, muscles in various parts of the body cavity are relaxed, and body fluids such as gastric fluid, lung fluid, ascites, and excreta are often leaked. In particular, the sphincter is relaxed in the anus, and internal dirt often leaks when the anus opens. In addition, the body may leak due to relaxation of muscles around the body cavity of the lower body such as the vagina of a woman. Along with that, problems such as bad odor, surrounding pollution, and post-mortem infection due to pathogenic bacteria have become problems. For this reason, for example, in hospitals, after confirming death, conventionally, a large amount of cotton wool, gauze, etc. is loaded into the body cavity of the corpse by an employee or nurse before rigor occurs after death to prevent leakage of filth in the body cavity. ing. However, loading work of absorbent cotton, gauze, etc. into the body cavity is complicated and unsanitary, and absorbent cotton, gauze, etc. have low water absorption capacity, so that filth often leaks during or after work. During work, there was a possibility of postmortem infection due to this spilled substance, and there was a strong need for a solution.

  For this reason, it is known that high water-absorbent resin powder is loaded into the mouth, nose, ears, throat, etc. instead of gauze, absorbent cotton, etc. A method of loading a water-absorbent resin powder (see Patent Document 1), or a method of using a water-absorbent resin powder containing stabilized chlorine dioxide wrapped in a water-soluble sheet in the ear throat and nostril while the powder remains in the throat. Patent Document 2) is known. However, even if such a superabsorbent resin powder is to be loaded, it is difficult to load a narrow body cavity such as the throat and anus because of poor fluidity. Moreover, if it is only the entrance part of a nostril or an ear canal, such fine powder can be filled with an injector like a syringe, but it cannot be filled to the back. Also, if you try to fill while moving the injector to fill the depths, the fine powder that comes out of the tip will scatter and only dirty around the body.

  In recent years, it has been proposed to use jelly instead of powder in order to solve problems such as poor filling properties and workability of such a highly water-absorbent resin powder and scattering. A method using a powdered polymer dissolved in an appropriate amount of water and mixed appropriately to form a jelly (see Patent Document 3), or a method using an amphiphilic gel containing dimethylacrylamide as a main component (Patent Document 4) And a method using a high-water-absorbing polymer powder dispersed in a jelly containing alcohol as a main component (see Patent Document 5). In addition, a cylindrical main body having a discharge port portion formed in a substantially hemispherical shape by a plurality of tongue pieces extending curved outward toward the center in the radial direction, and sliding from the rear end side to the cylindrical main body. Using a treatment device for a corpse in which a fibrous filler such as a jelly-like body fluid leakage preventing agent and a swellable fiber is contained inside the cylindrical body of an injector having a piston that is movably inserted, The tubular body is inserted into the anus and / or vagina, and a jelly-like body fluid leaks from an opening formed by a plurality of tongue pieces at the discharge port at the distal end of the tubular body and a slit between the tongue pieces. A method of extruding an inhibitor and a fibrous filler (see Patent Document 6 and Patent Document 7) is known.

  The jelly-like body fluid leakage preventing agent as described above has fluidity, has an advantage that it is easily filled even in a narrow body cavity such as a nostril or an ear hole, and does not scatter even if it is press-fitted with an injector. However, when only the jelly-like body fluid leakage preventing agent is injected and loaded into the body cavity of the corpse with an infusion device, it takes a relatively long time to absorb and expand the body fluid. There is a problem that it is easy to leak. Therefore, in order to seal the anus and vagina in particular, the fibrous filler is extruded together with the jelly-like body fluid leakage preventing agent, and the opening of the anus and vagina immediately after the injector is pulled out is plugged with the fibrous filler. There is a need. Therefore, after filling the cylindrical body with the jelly-like body fluid leakage preventing agent, it is necessary to fill the fibrous filler in a compressed state. However, the filling operation of the fibrous filler is performed manually. Therefore, the filling operation of the jelly-like body fluid leakage preventing agent and the fibrous filler into the injector is extremely cumbersome, resulting in poor workability and high cost.

  The corpse treatment apparatus of the present invention is a two-component foaming system comprising two liquids: (A) a liquid containing polyol (hereinafter referred to as liquid A) and (B) a liquid containing isocyanate (hereinafter referred to as liquid B). A treatment apparatus for simultaneously injecting and foaming the two liquids of a urethane composition into a body cavity of a corpse and sealing the body cavity of the corpse, the injection instrument comprising: a cylindrical body; Two cylindrical guide bodies each having a discharge cylinder portion that is covered with an easily breakable closed end surface, preferably a protective cap, at the front end portion, and from the rear end side in each cylindrical guide body Two pistons inserted slidably in a state where they can be operated simultaneously, and the liquid A is accommodated in one of the two cylindrical guide bodies, and the B is contained in the other one The connecting member that contains the liquid and is disposed in the cylindrical connecting member is the rear end. Has two needle-like connection tubes formed at an acute angle, and the cylinders are oriented so that the sharp end of each needle-like connection tube is oriented toward the closed end face (protective cap) side of each cylindrical guide body. Arranged in the connecting member. Therefore, at the start of use, an acute angle between the two needle-like connecting pipes of the connecting member can be obtained by a simple operation of connecting the connecting member to which the insertion pipe is connected to the distal end portion of the cylindrical body via the cylindrical connecting member. The end portion penetrates the closed end face of each cylindrical guide body, preferably the protective cap of the discharge cylinder portion, and the two flow paths of the insertion pipe connected to the needle-shaped connecting pipe communicate with the cylindrical guide bodies. It is in a state and has excellent operability at the start of use. Thereafter, the two pistons inserted into the two cylindrical guide bodies from the rear end side so as to be slidable are simultaneously operated and pushed to be accommodated in one of the two cylindrical guide bodies. The A liquid and the B liquid contained in the other one can be simultaneously injected into the body cavity of the body through the insertion tube and foamed, and the body cavity of the body can be sealed with urethane foam. Therefore, liquid A and liquid B of the two-component foamed urethane composition can be simultaneously and easily injected into the body cavity of the corpse with good workability, hygienically, quickly and effectively preventing body fluid leakage. It can be performed.

  In addition, the two-component foamed urethane composition (a body fluid leakage prevention agent) composed of two liquids of a liquid A containing polyol and a liquid B containing isocyanate used in the present invention is liquid in both liquid A and liquid B. In addition to being excellent in injectability with an injection device, when two liquids are injected into the body cavity of the body at the same time, it immediately reacts and foams to form urethane foam consisting of countless fine bubbles, even on the uneven parts of the body cavity It can be filled without any gaps, can be intimately adhered to the wall surface in the body cavity and hardened immediately, and the body cavity can be completely sealed. At this time, in order to absorb and retain the body fluid in the urethane foam and more effectively prevent the body fluid from leaking out, it is preferable that the A liquid and the B liquid generate a rigid urethane foam having open cells. The body fluid leakage prevention agent comprising the two-component foamed urethane composition used in the present invention is a two-component foamable urethane composition that produces a urethane foam having a high expansion ratio. In addition, since it is liquid, it can be easily injected into narrow body cavities using an injection device, so it is easy to seal body cavities such as the throat of the corpse, the anus, and the vagina. Thus, the body fluid leakage can be prevented hygienically, quickly and effectively.

  In a preferred aspect, the insertion tube has two tubes constituting the two flow paths therein, and the distal ends of the two tubes are connected to the distal ends of the insertion tubes. And a nozzle member in which one discharge flow channel communicating with the connection tubular portion is formed. By adopting such a configuration, compared to the case where the two flow paths are integrally formed in the insertion pipe, the manufacture of the insertion pipe having the two flow paths is facilitated and the manufacturing cost can be reduced. The liquid A and liquid B pushed out through one tube merge at one discharge flow path of the nozzle member and become agitated, so the liquid A and liquid B react, foam, and harden quickly, and immediately pass through the body cavity. It can be sealed. In addition, in the case of an insertion tube having a curved portion formed in a curved shape from the tip portion by a predetermined length, it can be easily inserted from the mouth of the body, and a body fluid comprising a two-component foamed urethane composition in the throat portion (throat portion) It is possible to quickly inject and load the leakage prevention agent. In particular, according to a preferred aspect in which the bending portion has a flat annular cross section whose dimension in the direction toward the bending center is smaller than the dimension in the direction perpendicular thereto, it can be inserted very smoothly from the mouth of the corpse, so that a quick treatment can be performed. This makes it possible to quickly prevent fluid leakage from the body's mouth. Further, in the case of a preferred embodiment having a stopper portion protruding radially outward at or near the connecting portion of the insertion tube, further insertion is prevented when the stopper portion hits the end of a body cavity such as a nostril or mouth. Therefore, without requiring skill in inserting the insertion tube, it is possible to inject and load the bodily fluid leakage prevention agent made of the two-component foamed urethane composition with the discharge port portion being surely positioned at a constant application site.

In another preferred embodiment, the cylindrical main body has a pair of hooks for hooking fingers protruding outward in the radial direction at or near the rear end thereof. By providing such a buttocks, it is possible to hook a finger on this, so that the injection operation is facilitated.
On the other hand, at the rear end of each piston, a pressing portion extended in the lateral direction is formed, and at the base of each pressing portion, a means for engaging with the other piston facing each other is provided, Preferably, an engaging piece projecting so as to extend below the pressing portion of the other piston facing each other and a hole portion into which the engaging piece is inserted are formed. With such a configuration, even if one pressing portion is pressed, the other engaging pressing portion is also pressed, so that the two pistons are pressed simultaneously. That is, with such a simple structure, it is possible to realize a state in which the pistons slidably inserted into the two cylindrical guide bodies can be engaged and operated simultaneously, and the two liquids can be operated by a single pressing operation. The liquid A and B of the foamed urethane composition can be simultaneously and easily injected into the body cavity with good workability.

  In a more preferred embodiment, the liquid A containing the polyol further contains a superabsorbent resin powder (C) and / or a fragrance (D). Since the superabsorbent resin powder (C) is dispersed in the liquid A, the superabsorbent resin powder dispersed in the injected urethane foam can absorb and swell body fluid more quickly and effectively, It is possible to more reliably prevent the body fluid from leaking. Further, the presence of the fine water-absorbent resin particles on the cell walls of the open-cell urethane foam makes it possible to absorb body fluid more quickly and effectively. Furthermore, as will be apparent from the test examples described later, by dispersing the highly water-absorbent resin powder in the liquid A, an effect of increasing the amount of foaming and increasing the amount of water retained after foaming can be obtained. This is thought to be because if the superabsorbent resin powder is mixed, the amount of foam increases because the liquid A and the liquid B are mixed well. Although it is thought for the same reason, the effect that the amount of foaming increases can also be obtained by adding the fragrance (D) to the liquid A.

  Furthermore, a corpse treatment device as a set for injecting and loading a two-component foamed urethane composition composed of two liquids, liquid A containing polyol and liquid B containing isocyanate, is inserted from the nostril or mouth. A treatment device for injecting and loading the throat and a treatment device for injecting and loading the anus and / or vagina, preferably for preventing leakage of body fluid from the ear canal, nostril, mouth, etc. Because it is equipped with at least one type of fiber sealing material for loading the ear hole, nostril, or mouth, it can be configured as a corpse treatment kit with all the necessary treatment tools in the container. This makes it possible to perform corpse treatment more quickly. Furthermore, by providing a fiber sealing material for preventing leakage of body fluid from the ear and / or nostril and a fiber sealing material for loading in the mouth, body fluid leakage due to relaxation of muscles in each part of the body cavity after death is further improved. It can be surely prevented.

  In particular, a treatment device for injecting and loading a bodily fluid leakage prevention agent comprising a two-component foamed urethane composition into the anus and / or vagina, which is preferably used in a corpse treatment device as a set, is inserted into the anus and / or vagina. A cylindrical main body having an opening at the tip formed in such a manner, and a discharge cylindrical portion disposed in the cylindrical main body, each of which is provided with an easily breakable closed end face, preferably a protective cap And two pistons that are slidably inserted into the respective cylindrical guides so as to be simultaneously operable from the rear end side. Two injectors in which one of the bodies contains the A liquid and the other one contains the B liquid; and two injectors disposed in the distal end of the cylindrical body. Because it has a nozzle device that can communicate with the cylindrical guide body Has excellent insertion operability into bodies of anal and / or vaginal, hygienically and quickly, it is possible to perform the leakage preventing fluid and filth from the body of the anus and / or vaginal effectively.

  In a preferred embodiment of the treatment apparatus for sealing the anus and / or vagina, the cylindrical main body has a substantially dome-shaped tip cover part having an opening at the tip, and the nozzle device is A tubular connecting portion connected to one cylindrical guide body, and a branch channel joined to the connecting portion, and a bifurcated channel is combined to form one discharge channel at the tip. Two needle-like connections formed at an acute angle toward the closed end face (protective cap) of each cylindrical guide body at a position corresponding to the bifurcated flow path of the connection portion Since the tube is disposed and the nozzle device is slidably disposed in the tip cover portion of the cylindrical main body, by simply pressing and sliding the nozzle device toward the injector at the start of use, The needle-shaped connecting tube is an easily breakable closed end surface of the tip of the cylindrical guide body, preferably Alternatively, it is possible to easily and reliably connect each injector to the above branch flow path through the easily breakable protective cap that is covered by the discharge cylinder at the tip of the cylindrical guide body. Excellent in properties. Further, in a preferred aspect in which the cylindrical main body has a stopper portion at a substantially intermediate portion and a pair of buttocks for hooking fingers protruding outward in the radial direction at the rear end portion, When the stopper part hits the opening part of the vagina or the vagina, further insertion is prevented, so that the discharge part is surely located at a constant application site and the body fluid leakage prevention agent consisting of a two-component foamed urethane composition In addition, by providing the above-described collar portion, it is possible to hook the finger on this, so that the injection operation is facilitated.

In order to solve the problems of the prior art as described above, the present invention is a corpse treatment apparatus according to a new method, which is composed of two liquids of liquid A containing polyol and liquid B containing isocyanate. A treatment apparatus for sealing a body cavity of a dead body by injecting the two liquids of the foamed urethane composition into the body cavity of the body and foaming them simultaneously is provided. In order to simultaneously inject and foam the two liquids of the two-component foamed urethane composition, liquid A and liquid B, into the body cavity of the body,
A cylindrical main body having two cylindrical guide bodies each having a discharge end portion having a cleavable closed end face at the tip portion and preferably covered with a protective cap; Two pistons inserted slidably in a state where they can be operated simultaneously from the rear end side, and the liquid (A) is accommodated in any one of the two cylindrical guide bodies, An injection device in which the liquid (B) is contained in the other one;
A tubular connecting member whose rear end is connected to the distal end of the tubular body;
It has two needle-like connecting pipes whose rear end portions are formed at an acute angle, and the sharp end portions of the needle-like connecting pipes are oriented toward the closed end face (protective cap) side of each cylindrical guide body. It is necessary to provide a connecting member disposed in the cylindrical connecting member.
Further, in a corpse treatment apparatus for injecting and loading a bodily fluid leakage prevention agent made of a two-component foamed urethane composition into the throat by inserting through the nostril or mouth, the two needle-like connecting tubes of the connecting member are further provided. It is necessary to provide the insertion pipe which has two flow paths connected to each front-end | tip part of this, and has a connection part connected to the said cylindrical connection member in a rear-end part.

  According to such a corpse treatment apparatus of the present invention, two cylinders are formed by simultaneously operating and pushing two pistons that are slidably inserted into the two cylindrical guide bodies from the rear end side. The A liquid contained in any one of the guide bodies and the B liquid contained in the other one can be simultaneously injected into the body cavity of the corpse through the insertion tube. Accordingly, the liquid A and the liquid B of the two-component foamed urethane composition can be simultaneously and easily injected into the body cavity of the corpse with good workability. The isocyanate and polyol injected into the body cavity such as the throat, anus, and vagina of the corpse react immediately to foam, forming urethane foam consisting of numerous fine bubbles, preferably open cells, and the uneven surface in the body cavity. It fills even fine parts without gaps, adheres to the wall surface in the body cavity and hardens immediately, becomes a rigid urethane foam, and can completely seal the body cavity.

  In order to reliably prevent liquid leakage from the two cylindrical guide bodies containing the A liquid and B liquid of the two-component foamed urethane composition during storage, the cylindrical guide body is discharged before use. It is preferable that the opening of the cylindrical portion is sealed and the insertion tube is communicated with the cylindrical guide during use. Therefore, the tip of each of the two cylindrical guide bodies into which the pistons are slidably inserted in a state where the pistons can be operated simultaneously from the rear end side is made an easily breakable closed end surface, preferably on the tip discharge cylinder portion. The connecting member disposed in the cylindrical connecting member to which the insertion tube is connected is formed with an acute angle at the rear end, while being disposed in the cylindrical main body in a state of being covered with an easily breakable protective cap. Two needle-shaped connecting pipes, and the sharp end portions of the needle-shaped connecting pipes are oriented toward the closed end face (protective cap) side of the cylindrical guide bodies. Arrange. By adopting such a configuration, at the start of use, the connection member to which the insertion tube is connected can be connected to the distal end portion of the cylindrical main body via the cylindrical connection member. The sharp ends of the two needle-like connecting pipes penetrate the closed end surfaces (protection caps of the discharge cylinders) of the respective cylindrical guide bodies, and the two flow paths of the insertion pipe connected to the needle-like connecting pipe are the above-mentioned It will be in a communication state with each cylindrical guide body. As a form of the protective cap, a form covered with a peelable seal sheet, a form in which the discharge cylinder part of the cylindrical guide body is covered with a thin plastic film and bonded by adhesion, heat shrinkage, etc., or a soft shape previously formed into a cap shape A form in which a protective cap made of plastic is fitted or joined is possible, but from the viewpoint of the workability of filling A liquid or B liquid, the workability of attaching the protective cap, etc. The form to join is preferable.

  The insertion tube has two flow paths connected to the respective tip portions of the two needle-like connection tubes of the connection member, and has a connection portion connected to the cylindrical connecting member at the rear end portion. There is no limitation to a specific form. For example, two flow paths are integrally formed inside the insertion tube, and a tubular portion connected to each tip of the two needle-like connection tubes of the connection member protrudes from the two flow channels. Alternatively, an insertion tube having two tubes constituting two flow paths inside may be used. Among them, the insertion tube having two flow paths is easy to manufacture, the manufacturing cost can be reduced, and from the viewpoint of connection operability to the respective tip portions of the two needle-like connection tubes, the inside of the insertion tube is 2 inside. An insertion tube having two tubes constituting one flow path is preferable.

  In addition, the liquid A and the liquid B of the two-component foamed urethane composition may be discharged simultaneously from the ends of the two flow paths, but as will be apparent from Test Example 1 described later, the liquid is reacted and foamed immediately after injection. For this purpose, it is preferable to inject the liquid A and the liquid B of the two-component foamed urethane composition into the body cavity of the corpse in a state of being stirred and mixed. For this purpose, it is preferable to have a structure in which the liquid A and the liquid B pushed out through the two flow paths merge at one discharge flow path of the nozzle member. As such a structure, a connecting tubular portion to which the distal ends of the two tubes or flow paths are connected and a single discharge flow channel communicating with the connecting tubular portion are formed at the distal end of the insertion tube. A form in which the nozzle member is inserted is preferable.

By providing such a stirring / mixing mechanism in the discharge flow path of the nozzle portion, the liquid A and the liquid B are mixed in the discharge flow path, and the two-component foamable urethane composition in a mixed state is obtained. Because it is injected into body cavities such as the throat, anus, and vagina of the corpse, the reaction between the liquid A, which is mainly composed of polyol, and the liquid B, which is based mainly on the isocyanate component, can be quickly reacted and foamed. it can.

  In addition, the shape of the insertion tube can be a flexible or flexible straight tubular shape or a curved portion formed by a predetermined length from the distal end so that it can be inserted into a narrow body cavity such as a nostril or mouth. It can be set as any form of having. In particular, in the case of an insertion tube inserted from the mouth, a form having a curved portion formed in a curved shape by a predetermined length from the distal end portion is preferable. By adopting such a form, the insertion tube can be easily inserted from the mouth of the corpse, and the bodily fluid leakage prevention agent composed of the two-component foamed urethane composition can be quickly injected and loaded into the throat (throat). In particular, in the case where the bending portion has a flat annular cross section whose dimension in the direction toward the bending center is smaller than the dimension in the direction perpendicular thereto, it can be inserted very smoothly from the mouth of the body, so that a quick treatment can be performed. Fluid leakage from the mouth can be prevented quickly. Furthermore, without requiring skill in inserting the insertion tube, the discharge port portion is always located at a fixed application site so that a body fluid leakage preventing agent made of a two-component foamed urethane composition can be injected and loaded. For this purpose, an insertion stop mark, a color display, or the like can be added at a predetermined position, but it is preferable to provide a stopper portion protruding radially outward at or near the connection portion of the insertion tube.

Further, the two cylindrical guide bodies of the injection device need to be fixed so as not to move into the cylindrical main body. This can be realized by various conventionally known fixing methods such as screwing and bonding, but preferably, a substantially annular recess is formed in the inner peripheral portion of the rear end portion of the cylindrical body, It can be realized by a simple structure in which a flange portion to be inserted into the concave portion is formed at the rear end portion of the cylindrical guide body of the injector, and the flange portion is fitted into the concave portion.

  By appropriately setting the thickness and length of the insertion tube described above, it can be used not only for sealing the nostrils and mouth but also for body cavities such as the ear canal. It can also be used as a treatment device for injecting and loading a bodily fluid leakage prevention agent comprising a two-component foamed urethane composition into the vagina. However, a treatment device for injecting and loading a body fluid leakage prevention agent comprising a two-component foamed urethane composition into a more suitable anus and / or vagina with a reduced number of parts is preferably inserted into the anus and / or vagina. A cylindrical main body having an opening at the formed tip; and a discharge cylindrical part disposed in the cylindrical main body, each of which is provided with an easily breakable closed end surface, preferably a protective cap.

The other includes two injectors in which the liquid B is accommodated; and a nozzle device that is disposed in the distal end portion of the cylindrical main body and communicates with the cylindrical guide body of the injector. . That is, the nozzle device is used in place of the cylindrical connecting member, the connecting member, and the insertion tube, thereby reducing the number of parts and the manufacturing cost, and the two-part type to the anus and / or vagina of the corpse. The injection operability of the body fluid leakage preventive agent comprising the foamed urethane composition is also excellent.

  The nozzle device is in communication with the cylindrical guide body of the injector in advance, and in order to prevent liquid leakage, the tip discharge port of the nozzle device is covered with a peelable seal sheet, or in a cap shape in advance. It is also possible to fit a molded soft plastic protective cap. However, in order to reliably prevent liquid leakage during storage, it is preferable that the nozzle device is not in communication before use and the nozzle device is in communication with the cylindrical guide body of the injector during use. In a preferred aspect of such a configuration, the cylindrical main body has a substantially dome-shaped tip cover portion having an opening at the tip, and the nozzle device is a tubular connecting portion connected to the two injectors. And a nozzle portion formed with a branch channel that is joined to the connection portion and has a bifurcated flow channel combined to form one discharge flow channel at the tip, and the bifurcated portion of the connection portion. Two needle-like connecting pipes that are disposed at positions corresponding to the flow channels and have sharp tips toward the discharge cylinder side of each of the injectors, and in the tip cover part of the cylindrical body It is preferable to be configured to be slidably disposed on the surface. On the other hand, it is preferable that each of the injectors has a discharge cylinder portion that is covered with an easily breakable protective cap at the tip portion. By adopting such a configuration, the needle-like connecting tube is covered with the discharge cylinder by simply sliding the nozzle device and connecting the connection to the discharge cylinder of the two injectors. The protective cap made from a thin film that can be easily broken is pierced, and each injector can be easily communicated with the above branch flow path, and should have excellent operability at the start of use. Can do.

  As the configuration in which the nozzle device is slidably disposed in the distal end cover portion of the cylindrical main body, any configuration that can be appropriately employed by those skilled in the art can be adopted, and preferably, the upper inner surface of the distal end cover portion and The lower inner surface has two guide ribs extending in parallel in the axial direction, and the nozzle device has guide pins protruding at two locations on the upper surface and the lower surface of the connecting portion, and each guide It is preferable that the pin is slidably disposed along the guide rib so that the pin is in sliding contact with the inner surface of the guide rib. In such a configuration, the needle-like connecting tube is pushed by the operation of simply pushing and pushing the nozzle device toward the injector at the start of use, and the easily breakable protective cap covered with the discharge tube portion is pushed. In addition, the communication between each injector and the branch channel can be performed easily and reliably.

  In addition, in order to insert the cylindrical main body into the anus or vagina so that the discharge port portion is located at a fixed application site, a method of placing a colored mark at a predetermined position of the cylindrical main body inserted into the anus or vagina However, it is preferable that the cylindrical main body is provided with a stopper portion, preferably a cap-shaped stopper portion, at a substantially intermediate portion. Due to the presence of such a stopper portion, it is possible to inject and load a body fluid leakage prevention agent made of a two-component foamed urethane composition with the discharge port portion positioned reliably at a constant application site without touching the body. it can. Furthermore, in order to improve operability, it is preferable to provide a pair of hooks for hooking fingers protruding outward in the radial direction at the rear end of the cylindrical main body. By providing such a buttocks, it is possible to hook a finger on this, so that the injection operation is facilitated. The stopper portion may be formed at a position away from the tip of the cylindrical main body by a predetermined distance depending on the site where the body fluid leakage prevention agent made of the two-component foamed urethane composition is injected and loaded. It is preferable to form in the substantially middle part of the main body.

  Furthermore, since the conventional injector for body fluid leakage prevention agent has a similar external shape to a general syringe, there is a possibility that a nurse may mistake a general syringe in a hospital. In the unlikely event that it is mistaken for a general syringe, it will be a serious medical accident and must be avoided. Since the injection device of the present invention has a special structure called a double injector, there is little risk of being mistaken for a general syringe, but only the cylindrical body of the injection device is colored or its color is different from the color of other members. By coloring the colorful injection device, it is possible for the nurse to easily discriminate it from a general syringe at the hospital or to clearly grasp the application place.

The two-component foamable urethane composition used in the present invention is not limited to a specific composition as long as it can react, foam and cure as quickly as possible.

What is necessary is just to select so that it may become in the range of 9-5.
Urethane foams include soft, hard, and semi-rigid products, but it is preferable to use rigid urethane foam because soft urethane foam and semi-rigid urethane foam take time to start foaming.

Use a mixture of the above. The amount of the foaming agent used is preferably adjusted so that the specific gravity of the formed urethane foam is 0.6 to 0.01, preferably 0.5 to 0.03.

  Examples of the catalyst (usually blended in the liquid A as the main agent) include, for example, amine-based catalysts (triethylenediamine, pentamethylenediethyltetramine, N-ethylmorpholine, diethylethanolamine, 1,8-diazabicyclo (5.4.0)).

Furthermore, alkylene oxide adducts of these amine compounds may also be used.

  Moreover, according to the suitable aspect of the two-pack type urethane foam composition used by this invention, a super absorbent polymer powder (C) is disperse | distributed to the A liquid which has the said polyol as a main component. As a result, the superabsorbent resin powder dispersed in the injected urethane foam absorbs and swells the body fluid more quickly and effectively, and solidifies into a non-flowable jelly (solid gel). Therefore, the body fluid leakage prevention of the corpse can be made more reliable. Moreover, by adding the highly water-absorbent resin powder, as shown in Test Example 2 described later, the amount of foaming increases and the amount of water retained after foaming increases. If the superabsorbent resin powder is mixed, it is considered that the amount of foaming increases because the liquid A and the liquid B are mixed well. However, if the superabsorbent resin powder is added excessively in order to increase the water retention amount, it is not preferable because it becomes difficult for the liquid to come out from the injection device. The amount of the superabsorbent resin powder added is about 0.01% by mass or more, about 30% by mass or less, preferably 20% by mass or less, more preferably 10% by mass with respect to the liquid A mainly composed of a polyol component. The following are appropriate.

  As the superabsorbent resin powder (C) used in the present invention, conventionally known superabsorbent resin powders can be used and are not limited to specific ones. Among them, polyvinyl acrylate, polyacrylic Acid salt, alginate, crosslinked acrylic acid graft copolymer, vinyl alcohol-polyacrylic acid copolymer, polyethylene glycol polymer, polyacrylamide resin, polyacrylic acid-maleic acid copolymer, polyethylene oxide polymer, And at least one selected from the group consisting of polyalginate-based polymers can be suitably used. The superabsorbent resin powder (C) preferably has a mean particle size of about 18 mesh to 200 mesh (in terms of Tyler), more preferably about 30 mesh to 200 mesh.

  When the superabsorbent resin powder (C) is dispersed in the liquid A containing a non-aqueous foaming agent, in order to increase the liquid absorption speed, a liquid polyethylene glycol having a heat generating action when contacted with water ( The average molecular weight of the degree of polymerization is about 200 to 600) and a small amount of nonionic surfactant can be used in combination. That is, in general, the water absorption rate of the highly water-absorbent resin powder (C) tends to increase as the temperature rises. Therefore, due to the exothermic action of the polyethylene glycol or nonionic surfactant when in contact with body fluid, The liquid absorption speed of the water absorbent resin powder (C) can be increased, whereby the highly water absorbent resin powder can quickly absorb and swell the body fluid and solidify into a solid jelly having no fluidity. Nonionic surfactants that generate heat when mixed with water and are liquid at room temperature include coconut oil fatty acid monoethanolamide, coconut oil fatty acid diethanolamide, polyoxyethylene coconut oil fatty acid monoethanolamide, lauric acid diethanolamide, polyoxyethylene. Lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene higher alcohol ether, polyoxyethylene polyoxypropylene glycol (a pluronic nonionic surfactant obtained by adding ethylene oxide to polypropylene glycol), polyoxyethylene alkyl (alkyl group carbon) Formula 12-14) Polyoxyethylene alkyl ether type such as ether (addition mole number of ethylene oxide: 7-12 mol), sorbitan fatty acid ester type, polyoxyethylene Surfactants such as sorbitan fatty acid esters and the like, can be used alone or in combination of two or more.

  Various dispersion stabilizers and thickeners can also be added to maintain uniform dispersibility of the highly water-absorbent resin powder (C) and adjust the viscosity of the liquid. The addition of these dispersion stabilizers and thickeners makes it easy to adjust the viscosity and widen the design tolerance for preventing liquid leakage from the injection device. That is, when the viscosity of the liquid is low, a tight seal mechanism is required to prevent liquid leakage from the extruding member (piston) side of the injection device, but in the case of a highly viscous liquid, the liquid leaks relatively. Since it becomes difficult, the sealing mechanism does not have to be so tight, and by adjusting the viscosity, it is possible to widen the design tolerance for preventing liquid leakage from the injection device. The dispersion stabilizer is preferably a polyalkylene oxide-based thermoplastic nonionic water-absorbing resin, but a carboxyvinyl polymer of an acrylic acid copolymer, a carboxyvinyl polymer / alkali neutralizing agent of an acrylic acid copolymer, Oily smectite, synthetic hectorite, natural hectorite, bentonite and the like can also be used. Examples of the thickener include sodium carboxymethyl cellulose, carboxymethyl cellulose, methyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone, sodium alginate and the like.

  Moreover, according to the other suitable aspect of the bodily fluid leakage prevention agent which consists of a two-component foaming urethane composition of this invention, it adds later by adding a fragrance | flavor (D) to the A liquid which has the said polyol as a main component. As shown in Test Example 3, the amount of foaming can be increased. It is thought that the amount of foaming increases because the liquid A and the liquid B are mixed well when a fragrance is mixed. However, it is not preferable to add an excessive amount of fragrance because it is difficult for the liquid to come out from the injection device or a sufficient foaming ratio cannot be obtained. The addition amount of the fragrance is about 0.001% by mass or more and about 10% by mass or less, preferably 5% by mass or less, with respect to the liquid A containing the polyol component as a main component. Examples of the fragrance include various natural and artificial fragrances such as floral, citrus, fruity, woody, fresh note, mixed flavor, green and mint.

  The body fluid leakage preventive agent comprising the two-component foamed urethane composition of the present invention can further contain a small amount of other additives such as bactericides, fungicides / preservatives, and deodorants as required. Moreover, it is also possible to contain a coloring agent (pigment, dye, pigment), and it is not particularly limited, such as selection of the blending amount and color tone, and can be arbitrarily set. Furthermore, if necessary, additives such as ordinary foam stabilizers, plasticizers, fillers, flame retardants, anti-aging agents, and antioxidants may be added in an appropriate amount range. About 0.001-8 mass% of the liquid to add is suitable for the compounding quantity of these additives, Preferably it is about 5 mass% or less. These additives are preferably added to the liquid A containing the polyol as a main component.

  The amount of the body fluid leakage prevention agent comprising the two-component foamed urethane composition of the present invention injected into the body cavity and filled can be appropriately set according to the application site, and sufficient foaming to prevent leakage of body fluid from the body cavity. The amount is not particularly limited as long as it is an amount.

At this time, since the guide rib 36 formed on the distal end connecting portion 32 of the cylindrical main body 3 slides in the notch recess 88 of the connecting member 8, it can be smoothly inserted. By inserting further, the sharp end of each needle-like connecting tube 84 of the connecting member 8 penetrates the protective cap 52 covered by the discharge cylinder portion 51 of each injector 4, and each tube 100 and each injection The inside of the cylindrical guide body 5 of the vessel 4 is in a communicating state, and the protrusion 48 formed at the distal end connecting portion 32 of the cylindrical main body 3 is fitted into the central opening 76a formed in the cylindrical connecting member 7, It will be locked.

  In the above state, the insertion tube 9 is inserted from the nostril toward the throat, and the insertion is stopped when the stopper portion 93 is located at the tip of the nose. At this time, in order to reduce the insertion resistance, a lubricant may be applied to the insertion tube main body 91 and the nozzle member 94. Then, the piston 6 of each injector 4 is pressed, and the liquid A of the two-component foamed urethane composition accommodated in one injector and the liquid B accommodated in the other injector are inserted into the insertion tube. 9 is simultaneously injected into the body cavity (throat) of the corpse through 9 and foamed, and sealed with urethane foam.

And B liquid react quickly and foam, forming urethane foam consisting of innumerable fine bubbles, preferably open cells, filling fine portions of uneven surfaces in body cavities without gaps, and sticking to wall surfaces in body cavities It can be cured immediately and the body cavity can be completely sealed. After filling with the urethane foam, the insertion tube 9 is extracted from the nostril. Alternatively, as another method, the insertion tube 9 in which the connecting member 8 and the cylindrical connecting member 7 are previously incorporated is inserted from the nostril toward the throat, and in this state, the distal end connecting portion of the cylindrical main body 3 of the injection device 2 is inserted. 32 may be inserted and connected from the rear side of the cylindrical connecting member 7, but the method described above is preferable from the viewpoint of workability.

  FIGS. 22 to 26 show another embodiment of an insertion tube suitable for injecting and loading a body fluid leakage preventing agent comprising a two-component foamed urethane composition into the throat (throat) after being inserted from the mouth. The connecting member 8 is shown connected to a cylindrical connecting member 7 mounted inside. The insertion tube 9a of this embodiment is different from the embodiment shown in FIGS. 18 to 21 in that the insertion tube main body 91a has a curved portion formed in a curved shape by a predetermined length from its distal end portion. The insertion tube body (curved portion) 9a has a flat annular cross section and is formed in a curved shape that approximates the shape of a human palate. In the case of the present embodiment, the entire insertion tube main body 91a is formed in a curved shape, a tapered connection portion 92 that opens rearward is formed at the rear end portion, and the front flange portion 74 of the cylindrical connecting member 7 is formed. Although functioning as a stopper portion, a straight tube portion may be provided between the insertion tube main body (curved portion) 91a and the connection portion 92, or a stopper portion 93 similar to the insertion tube 9 may be further provided.

  A nozzle member 94 is fitted into the distal end of the insertion tube main body (curved portion) 91a in the same manner as the embodiment shown in FIGS. 18 to 21. In this embodiment, the nozzle member 94 is different from the embodiment. The member 94 is formed in a two-part form, and by fitting a plurality of pins (not shown) formed on their end faces into a plurality of holes (not shown) formed on the other end face. Although assembled, it may be integrally molded. In addition, the connecting tubular portion 98 of the nozzle member 94 has an inner dimension larger than the total outer dimension of the two tubes 100 unlike the above-described embodiment, and the tube 100 is fitted into the inner peripheral portion of the rear end portion. A guide protrusion 98a is formed, and is a substantially oval inner peripheral surface formed by a pair of opposing guide protrusions 98a provided on the two-divided member equal to the total outer dimension of the two tubes 100? The inner dimensions are slightly smaller, and the two tubes 100 are inserted therein. In the illustrated embodiment, there is one guide protrusion 98a, but two or more guide protrusions may be provided at a predetermined interval.

  On the other hand, the connecting portion 92 at the rear end of the insertion tube 9a is provided at a predetermined angle at the rear end of the insertion tube main body (curved portion) 91a. The same as the embodiment shown in FIG. The bending direction of the insertion tube main body 91a, the directions of the flange portions 74 and 75 of the cylindrical connecting member 7, and the directions of the pair of flange portions 34 and the flange portion 35 of the cylindrical main body 3 are the same direction (shown in FIG. 24). In the state, it is oriented in the vertical direction) so that it can be easily inserted and injected through the mouth of the corpse, and the insertion tube 9a, the cylindrical connecting member 7 and the cylindrical main body 3 are assembled. The positioning is simple and the assembly can be easily performed. The assembling method of the insertion tube 9a, the two tubes 100, the cylindrical connecting member 7 and the connecting member 8 is the same as in the above-described embodiment.

  The insertion tube 9a is made of a relatively rigid plastic such as high-density polyethylene, polypropylene, polyester, polyamide, etc., and has an overall translucency, but may be colored so that the inside is not visible, It can also be made from any other plastic material. In addition, the insertion tube main body (curved portion) 91a has a certain amount so that even if the curved shape of the palate of the corpse to be treated is slightly different, it can be easily inserted smoothly from the corpse's mouth following the curved shape. It is preferable to have the flexibility. The front flange portion 74 of the cylindrical connecting member 7 with which the connecting portion 92 of the insertion tube 9a abuts functions as a stopper portion when the insertion tube main body (curved portion) 91a is inserted from the body's mouth toward the throat portion, Alternatively, since it functions as an insertion stop position display section, the entire length from the tip nozzle member 94 to the connection section 92 is the same as the length (insertion length) that the tip of the nozzle member 94 reaches the throat through the mouth. The outer diameter of the major part of the flat annular section of the curved portion is about 8 to 25 mm, preferably about 10 to 15 mm, and the outer dimension of the minor diameter is about 5 to 15 mm, preferably about 7 to 10 mm. It is. Further, a plurality of hole portions serving as preliminary openings when the discharge port (discharge flow path 97) of the nozzle member 94 at the front end is clogged can be provided on the side of the front end portion of the nozzle member 94.

The sharp end of the needle-like connecting tube 84 penetrates the protective cap 52 covered with the discharge cylinder 51 of each injector 4, and the tubes 100 and the inside of the cylindrical guide body 5 of each injector 4 communicate with each other. At the same time, the protrusion 48 formed at the distal end connecting portion 32 of the cylindrical main body 3 is fitted into the central opening 76a formed in the cylindrical connecting member 7 to be locked.

  In this state, the bending portion 91a of the insertion tube 9a is inserted from the body's mouth toward the throat. At this time, since the front flange portion 74 of the cylindrical connecting member 7 functions as a stopper portion, it can be inserted so that the discharge port is always located at a fixed application site without requiring skill in inserting the insertion tube. In order to reduce insertion resistance, a lubricant may be applied to the insertion tube main body 91a and the nozzle member 94. Then, the piston 6 of each injector 4 is pressed, and the liquid A of the two-component foamed urethane composition accommodated in one injector and the liquid B accommodated in the other injector are inserted into the insertion tube. It is simultaneously injected into the body cavity (throat part) of the body through 9a and foamed, and sealed with urethane foam. At this time, since one discharge flow path 97 is formed in the nozzle member 94 at the tip of the insertion tube 9a, the A liquid and the B liquid are merged, mixed, and discharged at this portion. And B liquid react quickly and foam, forming urethane foam consisting of innumerable fine bubbles, preferably open cells, filling fine portions of uneven surfaces in body cavities without gaps, and sticking to wall surfaces in body cavities It can be cured immediately and the body cavity can be completely sealed. After filling with the urethane foam, the insertion tube 9a is extracted from the mouth. Alternatively, as another method, the insertion tube 9a in which the connection member 8 and the cylindrical connecting member 7 are previously incorporated is inserted from the mouth toward the throat portion, and in this state, the distal end connection portion of the cylindrical main body 3 of the injection device 2 32 may be inserted and connected from the rear side of the cylindrical connecting member 7, but the method described above is preferable from the viewpoint of workability.

  In each of the above-described embodiments, each of the flange portions 34, 74, 75 and the flange portion 35 is substantially elliptical, but can be formed in an arbitrary shape such as a polygon such as a hexagon or an octagon. In addition, for example, the cylindrical main body 3 of the injection device 2 is colored or the color thereof is different from the color of other members so that the nurse can easily discriminate it from a general syringe at the hospital. By using a colorful and colorful injection device, it is possible to clearly grasp the place of application.

27 and 28 show a corpse treatment apparatus of the present invention provided with an insertion tube for injecting a body fluid leakage preventing agent made of a two-component foamed urethane composition into the throat (throat) after being inserted from the nostril or mouth. The other component is the same as the case of the said embodiment except the structure of the piston and the structure of the rear-end part of a cylindrical main body differing from the case of the said embodiment.
In this embodiment, as shown in FIG. 27, a circular flange 62a having a diameter slightly larger than the cross-sectional dimension of the piston rod is formed at the tip of the piston rod 61 having a cross-shaped cross section of the piston 6a. However, unlike the above-described embodiment, the front end surface of the circular flange portion 62a is not formed with a substantially mushroom-shaped flange portion, and the contents are pushed out directly at the front end surface of the circular flange portion 62a. It is configured. Therefore, the piston 6a can be integrally formed with a soft synthetic resin such as low-density polyethylene or silicone resin, and is advantageous over the above-described embodiment in that cost and assembly work are not required. Further, as shown in FIG. 28, the rear end portion of the cylindrical main body is covered with a cover portion 49 so that the ribs 44 cannot be seen, and has a clean appearance. In addition, the top end surface of the cover part 49 has a shape in which two semicircles are connected such that the outer periphery of the cylindrical guide body 5 is divided into two.

The other peripheral wall is formed with a stepped portion having a concave inner edge portion 116 having a cross-sectional shape corresponding to the protruding inner edge portion 115, the outer edge portion projecting and the inner edge portion side being recessed, and a predetermined position of one peripheral wall end surface Pins 117 are erected at a plurality of positions, and holes 118 are formed at a plurality of predetermined positions corresponding to the pins 117 on the other peripheral wall end face. The positional relationship of the protruding inner edge 115, the concave inner edge 116, the pin 117, and the hole 118 in the upper member 110a and the lower member 110b in the opened state is the same. Further, as shown in FIGS. 34 and 36, two guide ribs 151 extend in parallel to the axial direction at predetermined positions in the tip cover portion 112 inside the upper member 110a and the lower member 110b, respectively. A stopper rib 152 is provided at the rear end of the guide rib 151 and is provided in the vicinity of the cylindrical guide body 121 of the injector 120 so as to stand perpendicular to the axial direction. Note that reference numeral 153 shown in FIG. 34 denotes a plurality of support ribs erected at right angles to the axial direction in order to support the cylindrical guide body 121 of the injector 120 and reinforce the cylindrical main body 110. These top end surfaces are formed in a shape in which two semicircles corresponding to the elliptical outer shape of the cylindrical guide 121 are connected.

  As shown in FIGS. 31 to 34, the two injectors 120 arranged in the cylindrical main body 110 are each made of plastic such as high-density polyethylene, polypropylene, polyester, polyamide, ABS resin, acetal resin or the like. The cylindrical guide body 121 and the piston 130 are configured. One cylindrical guide 121 contains a liquid A mainly composed of polyol, and the other cylindrical guide 121 contains a liquid B mainly composed of isocyanate. The distal end portion of the cylindrical guide body 121 is reduced in diameter to have a discharge cylinder portion 122 having an outer diameter and an inner diameter smaller than the main body, and an annular flange portion 124 that protrudes in the radial direction is formed at the rear end portion. . The discharge cylinder 122 is covered with a protective cap 123 that is easy to break so as to cover the opening. In this embodiment, the cross-sectional shape of the cylindrical guide body 121 is elliptical as clearly shown in FIG. 35, but may be circular. Alternatively, it may be a polygon such as a hexagon or an octagon. However, when the amount of contents to be accommodated in the cylindrical guide body 121 is large, the cylindrical guide having an elliptical cross section is used when it is arranged in the cylindrical main body 110 having a circular cross section as in this embodiment. The body 121 is preferable from the viewpoint of effective space utilization (fillability). On the other hand, when the amount of contents to be accommodated in the cylindrical guide 121 is small, a circular shape is preferable from the viewpoint of easy manufacture. The cylindrical guide body 121 can be provided with a scale indicating at what position the capacity of the content is. In this embodiment, the discharge cylinder 122 at the tip of the cylindrical guide body 121 is covered with the easily-breakable protective cap 123, but easily breakable by a needle-shaped connecting tube 145 described later. For example, a thin film that is easy to break can be attached to the end surface of the discharge port or crowned on the discharge tube portion 122, but from the aspect of productivity and assembly, etc. It is preferable to use an easily breakable protective cap 123. Further, as a crowning method of the protective cap 123 to the discharge cylinder portion 122, any means such as fitting, adhesion, and screwing can be adopted.

  On the other hand, the piston 130 is slidably inserted into the cylindrical guide body 121 of each injector 120 from the rear end side. The length of the piston 130 is designed to be longer than the length of the cylindrical guide body 121 so that the entire contents can be pushed out. The piston 130 has a piston rod 131 having a substantially cross-shaped cross section, and as shown in FIG. 33, around a substantially mushroom-shaped flange portion 132 formed so as to protrude from the front end surface thereof, polytetrafluoroethylene or the like is provided. A gasket 133 made of soft synthetic resin such as fluorine resin, silicone resin, low density polyethylene, propylene copolymer, various elastomers such as polyester elastomer and polyurethane elastomer, rubber, etc. is covered. In addition, as a gasket material for the piston rod inserted into the cylindrical guide body containing the liquid B containing highly reactive polyisocyanate, fluorine resin such as polytetrafluoroethylene having excellent chemical resistance, silicone resin It is preferable to use a soft synthetic resin such as low-density polyethylene or propylene copolymer. Further, at the rear end of the piston rod 131, a substantially disk-shaped pressing portion 134 for touching the finger is formed so that the piston rod 131 can be easily pressed with the finger (see FIG. 37). The piston 130 is configured to slide in a state where the gasket 133 is in contact with the inner peripheral surface of the cylindrical guide body 121 when inserted into the cylindrical guide body 121 of the injector 120 from the rear end side. Yes. In this embodiment, the piston rod 131 has a substantially cross-shaped cross section, but may have a rod shape such as a circular cross section. Further, although the piston rod 131 and the gasket 133 of each piston 130 are separate bodies, they may be integrally formed, for example, a structure as shown in FIG. Furthermore, as in the case of the injection device 2 of the above-described embodiment, a ring-shaped ridge that slightly protrudes inward is formed on the inner peripheral surface in the vicinity of the rear end of the cylindrical guide body 121, and this ridge. It is also possible to provide a circular flange portion at the tip of the piston rod so as to hit the portion so that the piston 130 does not easily come out of the cylindrical guide body 121.

  Further, the width of the upper and lower pieces 135 of the cross-shaped cross section of each piston rod 131 is wider than the width of the left and right pieces 136 as is apparent from FIGS. In the vicinity, the width of the upper and lower pieces 135 is narrowed to be the same as the width of the left and right pieces 136. Further, two flat ribs 137 project from the pressing portion 34 in parallel so as to extend from the pressing portion 134 to the respective end faces of the upper and lower pieces 135 having a cross-shaped cross section whose width is narrow. 37, at the base of the pressing portion 134 on the side of the opposed flat plate rib 37, the piston rod 131 on the other side of the piston rod 131 between the upper flat plate rib 137 and the left and right pieces 136 is provided. Then, an engagement piece 138 is formed between the left and right pieces 136 and the lower flat plate rib 137 so as to protrude below the pressing portions 134 facing each other. Therefore, even if one of the pressing portions 134 is pressed, the engaging piece 138 of the other pressing portion 134 extending to the lower side is also pressed, so that the two pistons are pressed simultaneously. That is, the presence of the engagement piece 138 allows the two pistons to engage and operate simultaneously. The engaging means is a pair of upper and lower pairs of a cylindrical portion that opens to one piston rod side and a pin that is formed to protrude to the other piston rod side, as in the above-described embodiment. May be.

  The nozzle device 140 disposed in the distal end portion of the cylindrical main body 110 includes a connection portion 141 having a substantially elliptical outer shape having two cylindrical hole portions connected to the discharge cylinder portion 122 of the injector 120, and The nozzle portion 142 is joined to the connecting portion 141 and is formed with a branch channel 143 in which a bifurcated channel is combined to form one discharge channel 150 at the tip. Has a discharge port portion 144 formed in a substantially mushroom shape. As clearly shown in FIG. 38, two needles each having a sharp tip toward the discharge tube 122 side of the injector 120 are formed at the position corresponding to the bifurcated flow path of the connecting portion 141. A connecting pipe 145 is provided. The connection part 141 and the two needle-like connection pipes 145 may be integrally molded, or separate needle-like connection pipes are inserted into the holes of the connection part in which holes are formed at two predetermined positions, and bonded with an adhesive. May be. In addition, guide pins 146 protrude from two predetermined positions on the upper surface and the lower surface of the connecting portion 141, respectively.

  On the other hand, the nozzle part 142 is obtained by assembling and joining members divided into upper and lower parts, and as shown in FIGS. 31 and 32, a protrusion 147 is provided on one end face of each peripheral wall of the two parts. A groove 148 is formed on the end surface of the other peripheral wall, and the protrusion 147 of one member is fitted into the groove 148 of the other member while being fitted into the connection portion 141 and connected to the two divided members of the nozzle portion 142. The nozzle device 140 is assembled by bonding the part 141. In this embodiment, the nozzle portion 142 is formed by assembling and joining two divided members, but it may be integrally formed. Further, as shown in an enlarged view in FIGS. 34 and 38, the portion of the inner peripheral surface of the nozzle portion 142 where the bifurcated flow passages are combined to form one discharge flow passage 150 has two front and rear portions. A pair of baffle plate portions 149 having a predetermined height (preferably not more than about ½ of the inner diameter of the discharge flow channel 150 so that the outflow of the contents is not difficult) are opposed to each other, and A pair of baffle plates 149 on the front side and a pair of baffle plates 149 on the rear side are projected at a predetermined angle (about 30 to 60 °, preferably about 40 to 50 ° is desirable) with respect to the axial direction. Is shifted in the circumferential direction by an angle of 90 °. Alternatively, only a pair of baffle plate portions may be used, or a short spiral baffle plate portion may be formed. By providing such a baffle plate part 149, the nozzle part 142 can stir the liquid A mainly composed of polyol and the liquid B mainly composed of isocyanate, so that rapid foaming after injection occurs. . However, since the agitation effect due to the uneven surface of the inner wall of the body cavity can also be expected, there is no problem even if such a baffle plate portion 149 is not provided.

  When assembling the corpse treatment apparatus 1a, the two injectors 120 are disposed in the lower member 110b (or the upper member 110a) of the cylindrical main body 110, and the nozzle device 140 is disposed on the distal end side. The two injectors 120 have a flange formed at the rear end portion of the cylindrical guide body 121 of the injector 120 in an annular recess 119 formed at the inner peripheral portion of the rear end portion of the lower member 110b (or the upper member 110a). It arrange | positions so that the part 124 may fit (refer FIG. 34). Further, as shown in FIG. 36, the nozzle device 140 has two guide ribs 151 extending in the axial direction at predetermined positions in the lower member 110b and the upper member 110a of the cylindrical main body 110, respectively. The guide pins 146 projecting at two predetermined positions on the upper surface and the lower surface of the connecting portion 141 of the nozzle device 140 slide along the guide ribs 151 so as to be in sliding contact with the inner surfaces of the two guide ribs 151. Arrange freely. When the nozzle device 140 is slid toward the injector 120, the guide pin 146 comes into contact with the stopper rib 152 formed in the cylindrical main body 110, and when the nozzle device 140 is further pressed, the guide pin 146 However, the stopper rib 152 is configured to prevent the nozzle device 140 from being detached from the injector 120. Thereafter, the upper member 110a (or the lower member 110b) is fitted into the lower member 110b (or the upper member 110a), and the protruding inner edge 115 formed on one peripheral wall is fitted into the concave inner edge 116 formed on the other peripheral wall, In addition, the pins 117 erected at a plurality of predetermined positions on one end face of the peripheral wall are fitted into holes 118 formed at a plurality of predetermined positions on the end face of the other peripheral wall, and bonded with an adhesive as necessary. Assemble as shown in FIG. In general, since the corpse treatment device is a disposable product, after assembling as described above, it is bonded and assembled so that it cannot be disassembled. However, if only the injector 120 is disposable and the cylindrical body 110 is to be reused, The upper member 110a and the lower member 110b may be assembled by fitting into the hole 118 of the pin 117 and separated again. In this assembled state, the needle-like connecting tube 145 of the nozzle device 140 is not yet inserted through the protective cap 123 into the discharge cylinder portion 122 of the injector 120, and is in the state shown in FIG.

  When using the injection device (corporal treatment device) 1a for injecting and loading the body fluid leakage prevention agent comprising the two-component foamed urethane composition into the anus and / or vagina, first, from the tip of the cylindrical main body 110 Push the mushroom-shaped discharge port 144 at the tip of the nozzle part 142 of the protruding nozzle device 140, and slide the nozzle device 140 toward the injector 120 until the guide pin 146 of the nozzle device 140 gets over the stopper rib 152. The needle-like connecting tube 145 is inserted through the protective cap 123 covered with the discharge cylinder portion 122 of the injector 120, and the needle-like connecting tube 145 is inserted into the discharge cylinder portion 122. Thereby, the inside of the two injectors 120 is in communication with the branch flow path 143 of the nozzle device 140, respectively. Next, the distal end portion of the cylindrical main body 110 of the corpse treatment apparatus 1a is inserted into the anus or vagina, for example, and the insertion is stopped when the stopper portion 113 hits the outside of the anus or vagina. At this time, in order to reduce insertion resistance, a lubricant may be applied to the substantially dome-shaped tip cover portion 112 of the tubular body 110 of the corpse treatment apparatus 1a or further to the tubular portion reaching the stopper portion 113. Then, the piston 130 of the injector 120 is pushed, and the liquid A mainly composed of polyol and the liquid B mainly composed of isocyanate contained in the two injectors 120 are simultaneously injected into the anus and vagina. Then, the cylindrical main body 110 of the corpse treatment apparatus 1a is extracted from the anus and vagina. The corpse treatment apparatus 1a in a state after the injection is in a state as shown in FIG.

  If a cylindrical injection device with a large outer diameter is inserted into the anus or vagina after the death until it stiffens, the anal canal and the ostium of the vagina will open greatly, and it will take time to contract, causing leakage of bodily fluids. Further, the thinner the cylindrical body 110, the easier it is to insert and the easier it is to use. Therefore, it is desirable that the outer diameter of the cylindrical main body 110 is set within a range of about 15 to 30 mm, more preferably about 20 to 25 mm. Further, the distance from the tip of the cylindrical body 110 to the stopper portion 113 is desirably set within a range of about 30 to 75 mm, preferably about 40 to 60 mm, and the stopper portion 113 is separated from the outer peripheral surface of the cylindrical body 110. The height is preferably set within a range of about 5 to 30 mm so that it can easily stop at the anus or vaginal opening. Note that the stopper 113 does not necessarily have a cap shape as in this embodiment, and can be further inserted at a position where the cylindrical body 110 of the corpse treatment apparatus 1a is inserted into the anus or vagina by a predetermined length. Any member or mark can be used as long as it can be ensured, and for example, it may be disk-shaped or a mark that can be easily visually confirmed. Moreover, the front-end | tip part of the collar part 114 is curving a little forward so that a finger can be easily caught. The height of the flange 114 from the outer peripheral surface of the cylindrical main body 110 is preferably set within a range of about 5 to 25 mm, and the degree of curvature of the tip is within a range of 0 to 50 °.

  As mentioned above, although the suitable embodiment was shown about the corpse treatment apparatus concerning this invention, it is not restricted to the corpse treatment apparatus of an above described aspect, A various design change is possible unless it deviates from the summary of this invention. . In addition, for example, by coloring the cylindrical body or piston, or by coloring the color different from the color of other members to make a colorful injection device, it is possible to clearly grasp the application place. Is possible.

  Although the test example which confirmed the effect of this invention concretely is shown below, of course, this invention is not limited to the following test examples.

Test example 1
Quantitatively sample A liquid containing the polyol component as a main component and B liquid containing the isocyanate component as a main component in a two-component foamed urethane product manufactured by Nippon Paphtem Co., Ltd. at a ratio of 1: 1, respectively. At the same time, the graduated cylinder was gently shaken 4-5 times to measure the foaming start time, the foaming capacity, and the water retention after foaming when the liquid was mixed and when the liquid was not mixed. The foaming capacity is the capacity of the foam in the graduated cylinder, and the water retention amount is the amount of water added until water does not come out of the foam even if the graduated cylinder is inverted after adding water after foaming. Moreover, the room temperature at the time of measurement was 18-20 degreeC.
The test results are shown in Tables 1 and 2. In addition, the test result was shown by the average value tested repeatedly 3 times.

  As is clear from the test results shown in Tables 1 and 2 above, when the liquid A mainly composed of the polyol component and the liquid B mainly composed of the isocyanate component are mixed well, the reaction becomes faster and foaming is improved. If not mixed, the specific gravity of the liquid A and the liquid B is different, so two layers are formed, and since the reaction occurs gradually, the foaming deteriorates and the foaming start time becomes very slow. Incidentally, the specific gravity of A liquid is 1.10 (liquid temperature 20 degreeC), and the specific gravity of B liquid is 1.23 (liquid temperature 20 degreeC). Moreover, the hard foamed urethane after foaming was hardened and solidified in 6 to 8 seconds after foaming. From the above results, the discharge port of the injection device has a structure that stirs liquid A and liquid B. For example, a nozzle mechanism is provided so that liquid A and liquid B are stirred and mixed into the body cavity of the body. It can be seen that it is preferable to react and foam quickly.

Test example 2
Using a two-component foamed urethane product manufactured by Nippon Paphtem Co., Ltd., a superabsorbent resin powder with a ratio of 5 wt% to the liquid A mainly composed of polyol component (trade name “AQUAKEEP” manufactured by Sumitomo Seika Co., Ltd.) ) And B liquid mainly composed of isocyanate component in a ratio of 1: 1, respectively, are quantitatively sampled into syringes and simultaneously poured into a graduated cylinder, and then gently shaken the graduated cylinder 4-5 times. In the same manner as in Test Example 1, the foaming start time, foaming capacity, and water retention after foaming were measured. In addition, the room temperature at the time of measurement was 18-20 degreeC.
The test results are shown in Table 3. In addition, the test result was shown by the average value tested repeatedly 3 times.

  As is clear from the comparison of the test results shown in Table 3 above with the test results shown in Table 1, a liquid in which a superabsorbent resin powder is mixed in a liquid A containing a polyol component as a main component and an isocyanate component as a main component. When the liquid B was shaken and mixed, the foaming improved, the amount of foaming increased, and the amount of water retained after foaming increased because the amount of foaming increased and the superabsorbent resin powder was mixed in. . If the superabsorbent resin powder is mixed, it is considered that the amount of foaming increases because the liquid A and the liquid B are mixed well. However, if the superabsorbent resin powder is added excessively in order to increase the water retention amount, it is not preferable because it becomes difficult for the liquid to come out of the syringe.

Test example 3
Using a two-component foamed urethane product manufactured by Nippon Paphtem Co., Ltd., a fragrance at a ratio of 4 wt% to the liquid A mainly composed of a polyol component (manufactured by Kofu Co., Ltd., “trade name Deodorant 942-6189”, liquid ) And B liquid mainly composed of isocyanate component in a ratio of 1: 1, respectively, are quantitatively sampled into syringes and simultaneously poured into a graduated cylinder, and then gently shaken the graduated cylinder 4-5 times. The foaming start time and foaming capacity when mixing were measured in the same manner as in Test Example 1. In addition, the room temperature at the time of measurement was 18-20 degreeC.
The test results are shown in Table 4. In addition, the test result was shown by the average value tested repeatedly 3 times.

  As is clear from the comparison of the test results shown in Table 4 above with the test results shown in Table 1, a liquid in which a fragrance is mixed in a liquid A mainly composed of a polyol component and a liquid B mainly composed of an isocyanate component. When the liquid was mixed by shaking, the amount of foaming increased. This is thought to be because the liquid A and the liquid B easily become familiar with the addition of the fragrance.
