Description

  The present invention relates to a corpse treatment apparatus for preventing body fluid leakage by injecting and sealing a two-component foamed urethane composition into a body cavity of a corpse, particularly a body cavity such as an anus or a female vagina.

  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 absorbent cotton, gauze, etc. is loaded into the body cavity of the corpse by an employee or nurse before the body becomes rigid 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, in place of absorbent cotton, gauze, etc., a method of inserting a molded body made of a water-absorbing fiber mixed with a highly water-absorbent resin into a body cavity to suppress leakage of filth in the body has been performed (patent) Reference 1). However, this method is problematic in terms of hygiene because a molded body made of water-absorbing fibers is inserted into a body cavity by an employee or a nurse. Moreover, the operation of rounding the tip of the molded body made of water-absorbing fibers so as to be easily inserted into the body cavity is complicated. There is also known a method in which a molded body made of water-absorbing fibers is put into a cylindrical member and extruded into a body cavity. However, since all of them have a low water absorption capacity, there is a problem that filth often leaks.

  In order to solve the problems as described above, it has been recently proposed to use a jelly-like body fluid leakage preventing agent. For example, a cylindrical main body having a discharge port portion formed in a substantially hemispherical shape by a plurality of tongue pieces extending outwardly curved toward the center in the radial direction at the front end, 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 2 and Patent Document 3) is known.

  However, when only the jelly-like body fluid leakage prevention agent is injected and loaded into the anus or vagina 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 body fluid is likely to leak. Therefore, in order to seal the anus and vagina, as described in the above-mentioned patent document, 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 It is necessary to plug the part with a fibrous filler. 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.

  In addition, as another device for sealing the remains of the anus and vagina, an elastic rubber member is wound around the outer periphery of the core member, and a fluid introduction passage for inflating the elastic rubber member is formed inside the core member. An insertion member and an injector containing an amphiphilic gel are prepared, the insertion member is loaded into a body cavity, and the injector is set in an opening that opens to the outside of the body cavity of the introduction passage. A bodily fluid leakage prevention method characterized in that a medium gel is filled into the elastic rubber member through the core member, and the elastic rubber member is inflated to adhere to the inner wall of the body cavity to seal the body cavity (Patent Document) 4) has also been proposed. However, in such a method, the insertion member and the syringe containing the amphiphilic gel are connected, the insertion member is loaded into the body cavity, and the amphiphilic gel in the syringe is filled into the elastic rubber member. In addition to the problem that the workability is poor and it is difficult to quickly perform a body fluid leakage operation, and the number of devices is high and the cost is high, the elastic rubber member is inflated to adhere to the inner wall of the body cavity. Since it is a method of sealing a body cavity, there is a problem that it is difficult to prevent body fluid leakage effectively and reliably.

JP 2003-111830 A (Claims) Japanese Patent No. 4029106 (FIGS. 7 and 8) Japanese Patent No. 4081498 (FIGS. 7 and 8) JP 2001-288002 A (Claim 11)

A nozzle part in which a branch channel forming a channel is formed, and preferably disposed at a position corresponding to the bifurcated channel of the connecting part, on the discharge cylinder part side of each injector There are two needle-like connecting tubes formed with sharp tips toward the top, and are slidably disposed within the tip of the cylindrical body. On the other hand, each of the injectors has a discharge cylinder portion, which is covered with a protective cap made of an easily breakable thin film at the tip portion. Therefore, at the start of use, the nozzle device is pushed and slid to the injector side, and the connecting portion of the nozzle device is simply connected to the two injectors. A protective cap made from a thin film that is easy to break is pierced so that each injector can be easily communicated with the branch flow path, and the operability at the start of use is excellent.

  In another preferred embodiment, the cylindrical main body has a substantially dome-shaped tip cover portion having an opening at the tip, and extends in parallel in the axial direction on the upper inner surface and the lower inner surface of the tip cover portion. The nozzle device includes guide pins protruding at two locations on the upper surface and the lower surface of the connection portion, respectively, so that each guide pin is in sliding contact with the inner surface of the guide rib.

The piercing and communication between each injector and the branch channel can be performed easily and reliably.

  In still another preferred aspect, a baffle plate is provided at a predetermined angle with respect to the axial direction on the inner surface of the discharge channel of the branch channel of the nozzle unit. Due to the presence of the baffle plate portion, the liquid A and the liquid B are mixed in the discharge flow path of the branch flow path of the nozzle portion, and the mixed two-component foamable urethane composition becomes an anus of the corpse. Since it is injected into a body cavity such as the vagina or the vagina, the reaction between the liquid A containing polyol as a main component and the liquid B containing an isocyanate component as a main component is accelerated, and can be reacted and foamed quickly.

  In another preferred embodiment, a substantially disc-shaped pressing portion is formed at the rear end of each piston, and the pressing portion of the other piston facing each other is formed at the base of the pressing portion of each piston. Engagement pieces that protrude so as to extend below the respective portions are formed. With such a configuration, even if one of the pressing portions is pressed, the engaging piece of the other pressing portion that extends to the bottom 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 injectors can be engaged and operated simultaneously, and the two-component type can be realized by a single pressing operation.

In addition, by providing the above-described collar portion, it is possible to hook a finger on this, so that the injection operation is facilitated.

  In a preferred embodiment, the liquid A 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, by dispersing the highly water-absorbent resin powder in the liquid A, it is possible to increase the amount of foaming and to increase the water retention amount after foaming. 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.

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 device is provided for simultaneously injecting and foaming the two liquids of the foamed urethane composition into the body cavity of the corpse and sealing the anus and / or vagina of the corpse. 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 body having an opening at the tip;
Two injectors that are slidably inserted into the two cylindrical guide bodies disposed in the cylindrical main body from the rear end side so that the respective pistons can be operated simultaneously. , Two injectors containing the liquid (A) in one of them and the liquid (B) in the other,
It is necessary to provide a nozzle device which is disposed in the distal end portion of the cylindrical main body and can communicate with the cylindrical guide body of the injector.

  According to such a corpse treatment apparatus of the present invention, 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 anus and vagina of the corpse react immediately and foam, forming urethane foam consisting of innumerable fine bubbles, preferably open cells. Can be filled without any gaps, and can adhere to the wall surface in the body cavity and immediately harden to form a rigid urethane foam, which can completely seal the body cavity.

  The nozzle device can be previously communicated with the cylindrical guide body of the injector, and the tip discharge port of the nozzle device can be covered with a peelable seal sheet in order to prevent liquid leakage. 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 nozzle device includes a tubular connection portion connected to the two injectors, and a joint portion connected to the connection portion, and a bifurcated flow path is combined to form a tip portion. Each of the injectors, preferably arranged at a position corresponding to the bifurcated flow path of the connecting portion. It has the structure which has two needle-like connection pipes in which the acute angle tip was formed toward the discharge cylinder part side, and was slidably arranged in the tip part of the cylindrical main part. On the other hand, each of the injectors has a discharge cylinder portion that is covered with a protective cap made of a thin film that is easy to break at the tip. By adopting such a configuration, it is possible to easily break the needle-shaped connecting tube covered by the discharge cylinder portion by simply connecting the connecting portion of the nozzle device to two injectors. A protective cap made of a thin film is pierced so that each injector can be easily communicated with the branch flow path, and the operability at the start of use can be improved.

  As the configuration in which the nozzle device is slidably disposed in the distal end portion of the cylindrical main body, any configuration that can be appropriately adopted by those skilled in the art can be adopted, but preferably, the cylindrical main body has an opening at the distal end. And having two guide ribs extending in parallel in the axial direction on the upper inner surface and the lower inner surface of the tip cover portion, and the nozzle device includes the connection And a guide pin projecting at two locations on the upper surface and the lower surface of the portion, and the guide pin is slidably disposed along the guide rib so that the guide pin is in sliding contact with the inner surface of the guide rib. preferable. In the case of such a configuration, the needle-like connecting tube is made from an easily breakable thin film covered with the discharge cylinder portion by simply pushing the nozzle device toward the injector and sliding it at the start of use. The protective cap thus pierced can be easily and reliably communicated between each injector and the branch channel.

  Further, as will be apparent from Test Example 1 described later, in order to react and foam quickly after injection, the liquid A and the liquid B of the two-pack type urethane foam composition are stirred and mixed in the body cavity of the body. It is preferable to inject. For this purpose, it is preferable that the discharge port portion of the processing apparatus has a structure in which the A liquid and the B liquid are stirred and mixed. As such a stirring / mixing mechanism, preferably, the baffle plate portion, preferably the pair of baffle plate portions, are arranged in the axial direction on the inner surface of the discharge flow passage of the branch flow passage of the nozzle portion. On the other hand, it is possible to adopt a configuration that projects at a predetermined angle. In addition, a spiral baffle plate portion may be formed on the inner surface of the discharge flow channel of the nozzle portion to generate a vortex. 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. Since it is injected into body cavities such as the anus and vagina of the corpse, the reaction between the liquid A containing polyol as a main component and the liquid B containing an isocyanate component as a main component is accelerated, and can be reacted and foamed quickly.

  As described above, in order to simultaneously inject and foam the two liquids A and B of the two-pack type urethane foam composition into the body cavity of the dead body, the two liquid injectors are inserted into each cylindrical guide body. Each piston slidably inserted from the end side needs to be engaged in a state where it can be operated simultaneously. This engagement state may employ any configuration that can be appropriately selected by those skilled in the art, but preferably, a substantially disc-shaped pressing portion is formed at the rear end of each piston, It is preferable that the base is formed with engaging pieces that protrude so as to extend to below the pressing portions of the other pistons facing each other. With such a configuration, even if one of the pressing portions is pressed, the engaging piece of the other pressing portion that extends to the bottom 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 injectors can be engaged and operated simultaneously, and the two-component type can be realized by a single pressing operation. The liquid A and liquid B of the foamed urethane composition can be simultaneously and easily injected into the body cavity with good workability.

  Also, the two injectors need to be fixed so as not to move into the cylindrical body. This can be realized by various conventionally known fixing methods such as screwing and bonding. Preferably, an annular recess is formed in the inner peripheral portion of the rear end portion of the cylindrical body, and each of the injectors A flange portion that is fitted into the annular recess is formed at the rear end of the cylindrical guide body, and the flange portion is fitted into the annular recess.

  In addition, as described above, when a conventional injection device is inserted into the anus or vagina, there is a problem that it is difficult to insert so that the discharge port portion is always located at a fixed application site, and it is easy to touch without touching the body. It is desirable to be able to perform the injection operation. In order to position the discharge port portion at a fixed application site, a method of applying a colored mark at a predetermined position of the cylindrical body inserted into the anus or vagina can be adopted. It is desirable to provide 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 the body fluid leakage preventing agent with the discharge port portion reliably positioned at a constant application site without touching the body. 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 preventing agent is injected and loaded, but generally it is formed at a substantially intermediate portion of the cylindrical main body. Is preferred.

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. For example, a polyol is used as a main component. A two-component foaming urethane material composed of a liquid A having a main component and a liquid B having a polyisocyanate compound as a curing agent as a main component, and a foaming agent and, if necessary, a catalyst added to the liquid A. Can be mentioned. The reaction ratio of the main agent and the curing agent can be variously changed, but usually the equivalent ratio of the active hydrogen (OH group) of the main agent to the NCO group of the curing agent is 1: 0.8 to 10, preferably 1: 0. 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. Rigid urethane foam foams in a few seconds and hardens in a few seconds, so it is optimal for the intended purpose of preventing the body fluid leakage of the present invention.

  Moreover, according to the suitable aspect of the bodily fluid leakage preventive agent of 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 highly water-absorbent resin powder dispersed in the injected urethane foam absorbs and swells body fluids more quickly and effectively and solidifies into a solid jelly (solid gel) with no fluidity. Therefore, it is possible to more reliably prevent the body fluid from leaking. 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 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.

  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) is preferably a powder having an average particle size of about 18 mesh to 160 mesh (according to Tyler display), more preferably about 30 mesh to 140 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 preventing agent of the present invention, as shown in Test Example 3 to be described later, by adding a fragrance (D) to the A liquid mainly composed of the polyol, It is possible to increase the amount of foaming. 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 preventing agent of the present invention may further contain a small amount of other additives such as a bactericidal agent, a fungicide / antiseptic agent, and a deodorant 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. In general, these additives are preferably added to the liquid A if they are reactive, and may be added to either the liquid A or the liquid B if they are not reactive.

  The amount of filling and filling the body fluid leakage preventing agent of the present invention into the body cavity can be appropriately set depending on the application site, and may be a foaming amount sufficient to prevent leakage of body fluid from the body cavity, and is particularly limited. It is not something.

  Hereinafter, preferred embodiments of a corpse treatment apparatus according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.

1 to 9 show a preferred embodiment of a treatment apparatus for injecting and loading the body fluid leakage preventing agent into the anus and / or vagina. The corpse treatment apparatus is used as an injection device 1 of a double syringe type. It is configured.
The injection device 1 has a cylindrical body 10 made of a plastic such as high-density polyethylene, polypropylene, polyester, polyamide, ABS resin, or acetal resin, and is clearly shown in FIGS. And two injectors (hereinafter referred to as syringes) 20 disposed in the cylindrical main body 10 and a nozzle device 40 disposed in the distal end portion of the cylindrical main body 10.

  As shown in FIG. 1, the cylindrical main body 10 is a combination of an upper member 10 a and a lower member 10 b which are divided into two parts, a substantially dome-shaped tip cover portion 12 having an opening 11 at the tip, The middle portion has a cap-shaped stopper portion 13, and the rear end portion has a pair of hook portions 14 for hooking fingers protruding outward in the radial direction so as to be slightly curved forward. 4-6, the flange part 24 formed in the rear-end part of the cylindrical guide body 21 of the syringe 20 fits in the rear-end inner peripheral part of the upper member 10a and the lower member 10b. An annular recess 19 is formed to fit in. As shown in FIG. 7, the upper member 10 a and the lower member 10 b are formed with stepped portions on the end surfaces of the respective peripheral walls, each of which has a recessed outer edge side and a protruding inner edge portion 15 on the inner edge side. The other peripheral wall is formed with a step portion having a concave inner edge portion 16 having a cross-sectional shape corresponding to the protruding inner edge portion 15 by projecting the outer edge portion side and the inner edge portion side being recessed, and a predetermined position of one end face of the peripheral wall. Pins 17 are provided upright at a plurality of positions, and holes 18 are formed at a plurality of predetermined positions corresponding to the pins 17 on the other peripheral wall end face. The positional relationship among the protruding inner edge 15, the concave inner edge 16, the pin 17, and the hole 18 in the upper member 10a and the lower member 10b in the opened state is the same. Further, as shown in FIGS. 6 and 8, two guide ribs 50 extend in parallel in the axial direction at predetermined positions in the tip cover portion 12 in the upper member 10a and the lower member 10b, respectively. A stopper rib 51 is provided at the rear end of the guide rib 50 and is erected at a right angle in the axial direction located in the vicinity of the cylindrical guide body 21 of the syringe 20. In addition, the code | symbol 52 shown by FIG. 6 is the some support rib erected at right angles with respect to the axial direction in order to support the cylindrical guide body 21 of the syringe 20, and to reinforce the cylindrical main body 10. FIG. The upper end surfaces thereof are formed in a substantially arc shape corresponding to the elliptical outer shape of the cylindrical guide body 21.

  As shown in FIGS. 3 to 6, the two syringes 20 arranged in the cylindrical main body 10 are each made of a plastic such as high-density polyethylene, polypropylene, polyester, polyamide, ABS resin, or acetal resin. It is comprised from the cylindrical guide body 21 and piston 30 which were made. One cylindrical guide 21 contains a liquid A mainly composed of polyol, and the other cylindrical guide 21 contains a liquid B mainly composed of isocyanate. The distal end portion of the cylindrical guide body 21 is reduced in diameter to have a discharge cylinder portion 22 having an outer diameter and an inner diameter smaller than that of the main body, and an annular flange portion 24 protruding in the radial direction is formed at the rear end portion. . The discharge cylinder portion 22 is covered with a protective cap 23 made of an easily breakable thin film so as to cover the opening. In the present embodiment, the cross-sectional shape of the cylindrical guide body 21 is an elliptical shape as clearly shown in FIG. 7, but it may be a circular shape, or may be a hexagonal shape or an octagonal shape. It may be square. However, when arranged in the cylindrical main body 10 having a circular cross section as in the present embodiment, the cylindrical guide body 21 having an elliptical cross section is preferable from the viewpoint of effective space utilization (fillability).

  On the other hand, the piston 30 is slidably inserted into the cylindrical guide body 21 of each syringe 20 from the rear end side. The length of the piston 30 is designed to be longer than the length of the cylindrical guide body 21 so that the entire body fluid leakage preventing agent can be pushed out. As shown in FIG. 5, the piston 30 has a piston rod 31 having a substantially cross-shaped cross section. Around the mushroom-shaped flange portion 32 formed to protrude from the front end surface, an elastomer, a soft synthetic resin, rubber, etc. The gasket 33 made from is crowned. In addition, a substantially disc-shaped pressing portion 34 that touches the finger is formed at the rear end of the piston rod 31 so that the piston rod 31 can be easily pressed with the finger (see FIG. 9). The piston 30 is configured to slide in a state in which the gasket 33 is in contact with the inner peripheral surface of the cylindrical guide body 21 when inserted into the cylindrical guide body 21 of the syringe 20 from the rear end side. . In this embodiment, the piston rod 31 has a substantially cross-shaped cross section, but may have a rod shape such as a circular cross section.

  Further, the width of the upper and lower pieces 35 of the cross-shaped cross section of each piston rod 31 is narrower than the width of the left and right pieces 36 as is apparent from FIGS. In the vicinity, the width of the upper and lower pieces 35 is narrowed to be the same as the width of the left and right pieces 36. Further, two flat ribs 37 project from the pressing portion 34 in parallel so as to extend from the pressing portion 34 to the respective end surfaces of the upper and lower pieces 35 having a cross-shaped cross section whose width is narrow. As shown in FIG. 9, at the base portion of the pressing portion 34 on the side of the opposed flat plate rib 37, the other piston rod 31 is located between the upper flat plate rib 37 and the left and right pieces 36 in one piston rod 31. Then, an engaging piece 38 is formed between the left and right pieces 36 and the lower flat plate rib 37 so as to extend to below the opposing pressing portions 34. Therefore, even if one pressing portion 34 is pressed, the engaging piece 38 of the other pressing portion 34 extending to the lower side is also pressed, so that the two pistons are pressed simultaneously. That is, the presence of the engagement piece 38 allows the two pistons to engage and operate simultaneously.

  The nozzle device 40 disposed in the distal end portion of the cylindrical main body 10 is joined to the connection portion 41 having a substantially elliptical cross section connected to the discharge cylinder portion 22 of the syringe 20 and the connection portion 41, and is bifurcated. The nozzle part 42 is formed with a branch channel 43 having a discharge channel formed at the front end portion to form one discharge flow channel, and the nozzle portion 42 has a substantially mushroom-shaped discharge tip. An outlet 44 is provided. As clearly shown in FIG. 10, two needles each having an acute tip formed toward the discharge tube portion 22 side of the syringe 20 at a position corresponding to the bifurcated flow path of the connection portion 41. A connecting pipe 45 is provided. The connecting part 41 and the two needle-like connecting pipes 45 may be integrally molded, or a separate needle-like connecting pipe is inserted into the hole of the connecting part in which holes are formed at two predetermined positions, and an adhesive is used. You may join. In addition, guide pins 46 protrude from two predetermined positions on the upper surface and the lower surface of the connection portion 41.

  On the other hand, the nozzle part 42 is formed by assembling and joining members divided into upper and lower parts, and a protrusion 47 is formed on one peripheral wall end face of each of the two divided parts, and a groove 48 is formed on the other peripheral wall end face. Then, the protrusion 47 of one member is fitted into the connecting portion 41 while being fitted into the groove 48 of the other member, and the two divided members of the nozzle portion 42 and the connecting portion 41 are bonded to each other, thereby the nozzle device 40. Assemble. In this embodiment, the nozzle portion 42 is formed by assembling and joining two divided members, but it may be integrally formed. Further, as shown in an enlarged view in FIG. 6, a predetermined height (a bodily fluid leakage preventing agent) is formed on a partial inner peripheral surface of the nozzle portion 42 where the bifurcated flow passage is combined to form one discharge flow passage. The pair of baffle plate portions 49 are preferably about 1/2 or less of the inner diameter of the discharge flow path so as to prevent the outflow of the discharge flow path from each other and at a predetermined angle with respect to the axial direction. (Approximately 30 to 60 °, preferably about 40 to 50 ° is desirable). Alternatively, a short spiral baffle plate portion may be formed. By providing such a baffle plate part 49, the liquid A mainly composed of polyol and the liquid B mainly composed of isocyanate can be stirred by the nozzle part 42, so that rapid foaming after injection occurs. . However, since an agitation effect due to the uneven surface of the inner wall of the body cavity can be expected, such a baffle plate portion 49 may be omitted.

  When the injection device 1 is assembled, the two syringes 20 are disposed in the lower member 10b (or the upper member 10a) of the cylindrical main body 10, and the nozzle device 40 is disposed on the distal end side. The two syringes 20 are flange portions formed at the rear end portion of the cylindrical guide body 21 of the syringe 20 in the annular recess portion 19 formed at the inner peripheral portion of the rear end portion of the lower member 10b (or the upper member 10a). It arrange | positions so that 24 may fit (refer FIG. 6). In the nozzle device 40, two guide ribs 50 extend in the axial direction at predetermined positions in the lower member 10b and the upper member 10a of the cylindrical main body 10 as shown in FIG. Therefore, along the guide ribs 50, the guide pins 46 projecting at two predetermined positions on the upper surface and the lower surface of the connecting portion 41 of the nozzle device 40 are in sliding contact with the inner side surfaces of the two guide ribs 50. Place it slidably. When the nozzle device 40 is slid toward the syringe 20, the guide pin 46 comes into contact with the stopper rib 51 formed in the cylindrical main body 10, and when the nozzle device 40 is further pressed, the guide pin 46 is The connection between the nozzle device 40 and the syringe 20 is completed by overcoming the stopper rib 51, but the stopper rib 51 prevents the nozzle device 40 from coming off the syringe 20. Thereafter, the upper member 10a (or the lower member 10b) is fitted into the lower member 10b (or the upper member 10a), and the protruding inner edge 15 formed on one peripheral wall is fitted into the concave inner edge 16 formed on the other peripheral wall, In addition, the pins 17 erected at a plurality of predetermined positions on one end face of the peripheral wall are fitted into holes 18 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. Generally, 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, but only the syringe 20 is disposable and the cylindrical body 10 is to be reused, The upper member 10a and the lower member 10b may be assembled by fitting into the hole 18 of the pin 17 so that they can be separated again. In this assembled state, the needle-like connecting tube 45 of the nozzle device 40 has not yet been inserted through the protective cap 23 into the discharge cylinder portion 22 of the syringe 20 and is in the state shown in FIG.

  When using the injection device (corporal treatment device) 1 for injecting and loading the body fluid leakage preventing agent into the anus and / or vagina, first, the nozzle portion of the nozzle device 40 protruding from the tip of the cylindrical body 10 is used. The nozzle device 40 is slid toward the syringe 20 until the guide pin 46 of the nozzle device 40 gets over the stopper rib 51, and the needle-like connection tube 45 is discharged from the syringe 20. The needle-like connecting tube 45 is inserted into the discharge cylinder part 22 through a protective cap 23 made of a thin film which is covered with the cylinder part 22 and easily breakable. Thereby, the insides of the two syringes 20 are in communication with the branch flow paths 43 of the nozzle device 40, respectively. Next, the distal end portion of the injection device 1 is inserted into, for example, the anus or vagina, and the insertion is stopped when the stopper portion 13 hits the outside of the anus or vagina. At this time, in order to reduce the insertion resistance, a lubricant may be applied to the substantially dome-shaped tip cover portion 12 of the injection device 1 or a cylindrical portion reaching the stopper portion 13. Then, the piston 30 of the syringe 20 is pushed, and the liquid A mainly composed of polyol and the liquid B mainly composed of isocyanate contained in the two syringes 20 are simultaneously injected into the anus and vagina. Thereafter, the injection device 1 is extracted from the anus and vagina. The injection device 1 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 10 is, the easier it is to insert and the easier it is to use. Therefore, it is desirable to set the outer diameter of the cylindrical main body 10 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 10 to the stopper portion 13 is desirably set within a range of about 30 to 70 mm, preferably about 40 to 60 mm, and the stopper portion 13 is separated from the outer peripheral surface of the cylindrical body 10. 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. In addition, the stopper part 13 does not necessarily need to be in the shape of a cap as in this embodiment, and a member that can ensure that no further insertion can be performed at a position where the injection device 1 is inserted into the anus or vagina for a predetermined length. Alternatively, it may be a mark, for example, a disk shape, or a mark that can be easily visually confirmed. Moreover, the front-end | tip part of the collar part 14 is curving a little forward, so that a finger can be easily caught. It is preferable that the height of the collar portion 14 from the outer peripheral surface of the cylindrical main body 10 is set within a range of about 5 to 25 mm, and the degree of curvature of the tip portion 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. . Further, for example, by coloring the cylindrical main body 10 or the piston 30 or by coloring the color different from the color of other members to make a colorful injection device, the application place can be clearly grasped. It is also 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. The amount of the superabsorbent resin powder added is at most about 10 wt%, preferably 5 wt% or less, with respect to the liquid A containing the polyol component as a main component.

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.
