Description

  The present invention uses a body fluid leakage preventing agent injection insertion tube for preventing body fluid leakage from a body by loading and sealing the body cavity of a body, particularly a body cavity such as the mouth, nose, and ear, and the same. The present invention relates to a corpse treatment apparatus.

  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, causing malodor and infection by pathogenic bacteria. For this reason, for example, in hospitals, after confirming death, a large amount of gauze, absorbent cotton, etc. are loaded into body cavities such as the mouth, nose, ears, anus, and female vagina to prevent leakage of bodily fluids. Similar measures are also taken for the opening of the body after an accident or surgery. However, many of the operations for loading gauze, absorbent cotton, etc. into the body cavity are often performed by the hands of employees and nurses, etc., and at the same time the gauze, absorbent cotton, etc. have low water absorption capacity Therefore, there is a problem that body fluid often leaks during or after work, and there is a possibility of post-mortem infection due to this leaked substance during work, and there has been a strong demand 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).

  A filling method for filling such a jelly-like body fluid leakage preventing agent in, for example, the throat of the nostril will be described with reference to FIG. 1. As described in Patent Document 5, a jelly-like body fluid leakage prevention agent is described. The injector 1 in which the agent 2 is accommodated has a piston 3 slidably inserted from the rear end thereof, and has an injection port 4 covered with a protective cap 5 at its tip, and is a film pack (not shown). ) Wrapped and sealed. The insertion tube 6 to be inserted into a body cavity such as the throat B has a connection portion 7 connected to the injection port 4 of the injector 1 at one end and an opening portion 8 inserted into the nostril A at the other end.

  Next, a method for using the corpse treatment apparatus prepared in this way will be described. In FIG. 1, A is a nostril, B is a throat part, C is a tongue, D is a trachea, E is an esophagus. At the time of use, the injector 1 is taken out from the film pack, the protective cap 5 of the inlet 4 of the injector 1 is removed, and the connecting portion 7 of the insertion tube 6 is fitted to the inlet 4 to connect the insertion tube 6. Next, the opening 8 of the insertion tube 6 is inserted from the nostril A toward the throat B, and the insertion is stopped when the stopper portion 9 of the insertion tube 6 hits the nose tip B. Then, the piston 3 of the injector 1 is pressed, and the jelly-like body fluid leakage preventing agent 2 in the injector 1 is injected into the throat B through the insertion tube 6. After the body fluid leakage preventing agent 2 in the injector 1 is extruded and filled, the injector 1 and the insertion tube 6 are removed from the nostril A.

The jelly-like body fluid leakage preventing agent as described above has a high fluidity and is easily filled even in a narrow body cavity such as a nostril or an ear canal, and has an advantage that it does not scatter even if it is press-fitted with an injector. In particular, in the case of a jelly in which a large number of highly water-absorbing polymer powders are dispersed, the water-absorbing performance is high, and it is possible to prevent the polymer from absorbing body fluid leaking from the body cavity and leaking to the outside. However, in the case of the combination of the conventional injector and the insertion tube, there is a problem in its operability, and since there is a mark or a stopper portion indicating the insertion stop position in the middle portion of the elongated insertion tube, the insertion of the insertion tube However, there is a problem that it is difficult to reliably inject and load the body fluid leakage preventing agent at a constant application site. In addition, since there is an opening at the distal end of the insertion tube, there is also a problem that it is blocked when the distal end opening comes into contact with the application site and it is difficult to inject the body fluid leakage preventing agent.

  Therefore, the object of the present invention is excellent in operability, without requiring skill in inserting the insertion tube, and can always inject and load the body fluid leakage preventing agent with good workability into a fixed application site. It is an object of the present invention to provide an insertion tube for injecting a body fluid leakage preventing agent and a corpse treatment apparatus using the same.

  In order to achieve the above object, according to the present invention, there is provided a body fluid leakage preventing agent injection insertion tube for a corpse, the first aspect of which is a flexible synthetic resin insertion tube, And a discharge cylinder portion of a body fluid leakage prevention agent injector provided at the rear end portion of the insertion tube main body, and the insertion tube main body having a plurality of apertures on the side surface. And a stopper portion protruding outward in the radial direction at a predetermined position on the insertion tube main body side of the connection portion.

Further, the second aspect is a flexible synthetic resin insertion tube, the tip portion of which is formed in a substantially hemispherical shape by a plurality of tongue pieces extending outwardly curved toward the radial center. An insertion tube body in which an opening formed by an opening formed by the tips of the plurality of tongue pieces and a slit between the tongue pieces is formed, and injection of a body fluid leakage preventing agent provided at the rear end portion of the insertion tube body And a stopper portion protruding radially outward at a predetermined position on the insertion tube main body side of the connecting portion.
According to a preferred aspect of any of the above, the insertion tube main body has a curved portion at a position away from the tip by a predetermined distance.

Furthermore, according to the present invention, the insertion tube for injecting the body fluid leakage prevention agent; a discharge cylinder portion for connecting to the connection portion of the insertion tube at the tip, and a radially outer side for hooking a finger to the rear end portion And a body fluid leakage preventing agent injector having a cylindrical main body having a flange protruding to the bottom and a piston slidably inserted into the cylindrical main body from the rear end side. A corpse treatment device is provided.
In a preferred aspect, the cylindrical main body of the injector for body fluid leakage prevention agent comprises a cylindrical member having a discharge cylindrical portion at the tip and a cover member covered on the outer periphery thereof, and the collar portion is the above-mentioned The cover member is provided, and the piston is slidably inserted into the cylindrical member.

  According to the first aspect of the insertion tube for injecting a bodily fluid leakage preventing agent for a dead body according to the present invention, the distal end portion of the flexible synthetic resin insertion tube main body is formed in a substantially hemispherical shape, and Since there are multiple openings on the side, the insertion tube can be inserted smoothly from the nostril to the throat, and it is difficult to inject the body fluid leakage prevention agent when the tip opening contacts the application site. There is no problem, and the body fluid leakage preventing agent can be injected and loaded smoothly. In addition, it has a connection part for connecting to the discharge cylinder part of the injector for injecting bodily fluid leakage preventing agent provided at the rear end part of the insertion pipe main body, and radially outside the predetermined position on the insertion pipe main body side of this connection part The length of the insertion can be shortened compared to the case where a stopper is provided in the middle of the elongated insertion tube, and the insertion tube can be inserted smoothly without requiring skill. In addition, it is possible to inject and load the bodily fluid leakage preventing agent with the opening portion being surely positioned at a constant application site.

  On the other hand, according to the second aspect of the insertion pipe for injecting a bodily fluid leakage preventing agent for a dead body according to the present invention, the distal end portion of the flexible synthetic resin insertion pipe body is curved outward toward the radial center. A plurality of tongue pieces extending in a substantially hemispherical shape and an opening formed by an opening formed by the tips of the plurality of tongue pieces and a slit between the tongue pieces are formed. When the body fluid leakage preventing agent is pushed out by the piston, the body fluid leakage preventing agent pushes out the plurality of tongue pieces and also comes out of the slits between the widened tongue pieces, so that the surface area is increased. Therefore, when it comes into contact with the body fluid in the body cavity, it quickly absorbs liquid and becomes a solid gel without fluidity, and it becomes possible to prevent body fluid leakage more effectively and quickly. In addition, it has a connection part for connecting to the discharge cylinder part of the injector for injecting bodily fluid leakage preventing agent provided at the rear end part of the insertion pipe main body, and radially outside the predetermined position on the insertion pipe main body side of this connection part The length of the insertion can be shortened compared to the case where a stopper is provided in the middle of the elongated insertion tube, and the insertion tube can be inserted smoothly without requiring skill. In addition, it is possible to inject and load the bodily fluid leakage preventing agent with the opening portion being surely positioned at a constant application site.

  Further, according to a preferred aspect of the insertion tube for injecting a bodily fluid leakage preventive agent for a corpse, the insertion tube body has a curved portion at a position away from the tip by a predetermined distance, and therefore is inserted from the nostril to the back of the pharynx. At this time, the insertion tube can be inserted smoothly without resistance.

  Furthermore, the corpse treatment device of the present invention has the above-described insertion tube for injecting a body fluid leakage preventive agent; and a discharge cylinder portion for connecting to the connection portion of the insertion tube at the tip, and hooks a finger on the rear end portion. A body fluid leakage preventive injector having a cylindrical main body having a flange projecting radially outward and a piston slidably inserted into the cylindrical main body from the rear end side. Therefore, it has the effect of using the insertion tube as described above, and has a buttocks for hooking a finger to the rear end of the cylindrical main body, so that the operation of injecting the body fluid leakage preventing agent into the body cavity of the corpse can be performed more easily. It can be performed with good workability.

  Furthermore, in a preferred embodiment of the corpse treatment apparatus, the cylindrical main body of the body fluid leakage preventing agent injector comprises a cylindrical member having a discharge cylinder portion at the tip and a cover member covered by the outer periphery thereof. The flange portion is provided on the cover member, and the piston is slidably inserted into the cylindrical member, so that a cylindrical body can be easily manufactured at a lower cost than in the case of integral molding. A nurse in a hospital can make a colorful syringe by making the cover member into a polygonal cross-section, coloring the cover member, or coloring it differently from the color of other members. However, it can be easily discriminated without making a mistake with a general syringe, or the application place can be clearly grasped.

  The first feature of the insertion tube for injecting a bodily fluid leakage preventive agent according to the present invention is that the distal end portion of the flexible synthetic resin insertion tube body is formed in a substantially hemispherical shape. The insertion tube can be inserted smoothly from the nostril to the throat. According to the first aspect, the distal end portion of the insertion tube main body is formed to be closed in a substantially hemispherical shape and has a plurality of opening portions on the side surface thereof, so that the body fluid is blocked when the distal end opening abuts. There is no problem that it becomes difficult to inject the leakage preventing agent, and the body fluid leakage preventing agent can be sufficiently injected.

  On the other hand, in the second aspect, the distal end portion of the insertion tube main body is formed in a substantially hemispherical shape by a plurality of tongue pieces extending outwardly curved toward the radial center, and the distal ends of the plurality of tongue pieces The opening part which consists of a slit between the opening and tongue piece formed by is formed. Therefore, the bodily fluid leakage prevention agent can be sufficiently injected, and when the bodily fluid leakage prevention agent filled in the injector is pushed out by the piston, the bodily fluid leakage prevention agent pushes out a plurality of tongue pieces and comes out, Since it also comes out from the slit between the expanded tongue pieces, its surface area becomes large. Therefore, when it comes into contact with the body fluid in the body cavity, an additional effect is obtained that the fluid is quickly sucked into a solid gel without fluidity, and the body fluid leakage can be prevented more effectively and quickly.

  The second feature common to any of the above-described insertion pipes for injecting bodily fluid leakage prevention agent is connected to the discharge cylinder of the bodily fluid leakage prevention agent injector provided at the rear end of the insertion tube body. And a stopper portion protruding radially outward at a predetermined position on the insertion tube main body side of the connection portion. For this reason, the length between insertions can be shortened compared to the case where a stopper is provided in the middle part of the elongated insertion tube, the insertion tube can be inserted smoothly without requiring skill, and always constant. The opening portion is surely positioned at the application site, and the body fluid leakage preventing agent can be injected and loaded. Further, when inserting from the nostril to the back of the pharynx, it is preferable to provide a curved portion at a position away from the distal end of the insertion tube main body by a predetermined distance so that the insertion tube can be smoothly inserted without resistance. The insertion tube main body and the connection portion may be integrally formed or may be separate. In the case of a separate body, the connecting portion is preferably formed of a rigid synthetic resin, and the connecting portion and the insertion tube main body are joined by appropriate means such as an adhesive or welding. Further, the stopper portion 44 may be formed at the tip of the connection portion, or may be formed at an intermediate portion of the connection portion.

  Furthermore, the corpse treatment apparatus of the present invention has the first feature of using the above-described insertion tube for injecting bodily fluid leakage preventive agent, but as the second feature, the cylindrical body of the infusion device for bodily fluid leakage preventing agent is used. It is in the point which has the collar part projected on the radial direction outer side for hooking a finger | toe at a rear-end part. By providing such a buttocks, a finger can be hooked on this, so that the injection operation is facilitated.

  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. For that purpose, it is preferable to divide the cylindrical main body of the injector for body fluid leakage preventing agent into a cylindrical member having a discharge cylindrical portion at the tip and a cover member covered with the outer periphery thereof. As a result, in addition to the advantage that the cylindrical main body can be easily manufactured at a lower cost than in the case of integral molding, the cover member has a polygonal cross-sectional shape, the cover member is colored, or the color is different. By making it a colorful injector by coloring it differently from the color of the member, it is possible for the nurse to easily distinguish it from a general syringe in the hospital or to clearly grasp the application place Can do.

Hereinafter, specific examples of each aspect of a body fluid leakage preventing agent injection insertion tube and a corpse treatment apparatus using the same will be described with reference to the accompanying drawings.
2 to 5 show a treatment apparatus for injecting and loading the body fluid leakage preventing agent into the throat by inserting from the nostril. FIGS. 2 to 4 show the injector 10 and FIG. The tube 40 is shown, and the symbol X indicates the body fluid leakage preventing agent accommodated in the injector 10.

  2 to 4 show the injector 10, FIG. 4 shows a cross-sectional view of the state rotated by 90 ° around the center line from the state shown in FIG. 2. As shown in FIGS. 2 to 4, the injector 10 includes a cylindrical main body 20 and a piston 30 each made of a plastic such as high-density polyethylene, polyester, and polyamide. The cylindrical main body 20 includes a cylindrical member 21 having a discharge cylinder portion 22 at the tip, and a cover member 25 that is covered with an outer periphery thereof.

  As is clear from FIG. 2, the cover member 25 is a cylinder having an octagonal cross section. The cover member 25 is configured so that a nurse can easily discriminate it from a general syringe in a hospital, and the tip side is slightly tapered. It is formed in a tapered shape so that it does not easily fall off when the cylindrical member 21 is inserted. In addition, it is also possible to make it possible to clearly grasp the application place by coloring the cover member or coloring the cover member so that it is different from the color of other members to form a colorful injector. As clearly shown in FIG. 4, the cover member 25 has a pair of flange portions 26 protruding outward in the radial direction for hooking a finger to the rear end portion. The distal end portion of the collar portion 26 is curved in the direction of the discharge cylinder portion 22 so that the finger can be easily caught. It is preferable that the height of the collar portion 26 from the outer peripheral surface of the cylindrical member 21 is set within a range of about 5 to 18 mm, and the degree of curvature of the tip portion is within a range of 0 to 50 °. Further, a pair of convex locking portions 23 are formed at the rear end of the cylindrical member 21, and when the collar portion 26 comes into contact with the locking portion 23, a finger is hooked on the collar portion 26 and injected. When the operation is performed, the cover member 25 is configured not to move backward from the rear end of the cylindrical member 21. Moreover, the protective cap 29 is removably crowned at the distal end opening of the discharge cylinder portion 22 after the body fluid leakage preventing agent of the present invention is filled in the injector 10. In this embodiment, the cylindrical member 21 and the cover member 25 are formed separately, but may be integrally formed.

  On the other hand, the piston 30 is slidably inserted into the cylindrical member 21 of the cylindrical main body 20 from the rear end side. The length of the piston 30 is designed to be longer than the length of the cylindrical member 21 so that the whole body fluid leakage preventing agent X of the contents can be pushed out. The piston 30 has a piston rod 31 having a cross-shaped cross section, and a circular flange portion 32 having a diameter slightly larger than the cross-sectional dimension of the piston rod is formed at the tip portion thereof. A gasket 34 made of synthetic resin, rubber or the like is crowned around the flange portion 33 formed so as to protrude from the circular flange portion 32. In addition, a disc-like portion 35 for touching 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. When the piston 30 is inserted into the cylindrical member 21 of the cylindrical main body 20 from the rear end portion side, the piston 34 passes through the cylindrical member 21 with the gasket 34 in contact with the inner peripheral surface of the cylindrical member 21 of the injector 10. It is configured to slide. Further, a ring-shaped ridge portion 24 protruding slightly inward is formed on the inner peripheral surface in the vicinity of the rear end portion of the cylindrical member 21, and the circular flange portion of the piston rod 31 is formed on the ridge portion 24. The piston 30 is configured not to easily come out of the cylindrical main body 20 when it hits 32. In this embodiment, the piston rod 31 has a cross-shaped cross section, but may have a rod shape such as a circular cross section.

  The insertion tube 40 is made of a flexible synthetic resin such as a polyester elastomer, a soft vinyl chloride resin, or a rubber having a flexibility of bending along the shape of the nasal cavity when inserted into the nostril. As shown in FIG. 5, the insertion tube 40 includes an insertion tube main body 40a and a connection portion 43, and the distal end portion 41 of the insertion tube main body 40a is formed in a substantially hemispherical shape so as to be easily inserted from the nostril and is closed. In addition, a pair of opening portions 42 in the direction perpendicular to each other are provided at two positions shifted on the side surface, and connected to the discharge cylinder portion 22 of the injector 10 at the rear end portion. A tapered connecting portion 43 that is slightly expanded is provided on the rear side. Further, a stopper 44 having a circular cross section protruding outward in the radial direction so as to surround the outer periphery is formed at a predetermined position on the insertion tube main body side of the connection portion 43 (preferably the tip position of the connection portion 43). The diameter of the stopper portion 44 needs to be sized so as not to be inserted into a desired body cavity such as a nostril.

  The opening 42 at the distal end of the insertion tube 40 can be a hole having a desired shape such as a circle or an ellipse, and the position is preferably a distance of about 5 to 30 mm from the distal end of the insertion tube. Moreover, although the number of the aperture parts 42 is four in this embodiment, it may be an arbitrary number of about 2 to 6. The stopper portion 44 determines the length (injection position) that the opening portion 42 reaches when the insertion tube main body is inserted into the pharynx through the nostril, but from the distal end of the insertion tube main body 40a. The length is preferably about 100 to 140 mm, and the outer diameter of the insertion tube main body 40a is preferably about 3.5 to 7 mm, and the inner diameter is preferably about 2 to 5 mm.

  When using the corpse treatment apparatus, first, the protective cap 29 of the discharge tube portion 22 of the injector 10 is removed, and the discharge tube portion 22 is fitted into the connection portion 43 of the insert tube 40 to connect the insert tube 40 and the injector 10. Connecting. Next, the insertion tube main body 40a is inserted from the nostril A (see FIG. 1) toward the throat B, and the insertion is stopped when the stopper portion 44 of the insertion tube 40 hits 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 40a. Then, the piston 30 of the injector 10 is pressed, and the jelly-like body fluid leakage preventing agent X in the injector 10 is injected into the throat B through the insertion tube 40. After the body fluid leakage preventing agent X in the injector 10 is extruded and filled, the injector 10 and the insertion tube 40 are extracted from the nostril A. In the above operation method, the insertion tube 40 is inserted into the nostril A while being connected to the injector 10, but the insertion tube 40 is first inserted into the nostril A, and then the injector 10 is connected to the insertion tube 40. Also good.

FIG. 6 shows a modification of the distal end portion of the insertion tube for injecting a body fluid leakage preventing agent according to the present invention.
In this modification, as shown in FIG. 6, the distal end portion of the insertion tube main body 40a is formed in a substantially hemispherical shape by a plurality of tongue pieces 45 extending outwardly curved toward the radial center, and An opening formed by an opening formed by the tips of the plurality of tongue pieces 45 and a slit between the tongue pieces is formed. Each tongue 45 has a flexibility that can be bent outward. Therefore, when the fluid leakage preventive agent filled in the injector is pushed out by the piston, the fluid leakage preventing agent pushes out the plurality of tongue pieces and also comes out from the slits between the expanded tongue pieces. Its surface area is increased.

FIG. 7 shows another embodiment of an insertion tube for injecting a body fluid leakage preventing agent according to the present invention.
In this embodiment, the insertion tube main body 40a is the same as the insertion tube shown in FIG. 5 except that the insertion tube main body 40a is bent at a predetermined position from the distal end portion. By forming such a curved portion 46, when inserting from the nostril to the back of the pharynx, it can be smoothly inserted without resistance. The bending position is preferably an arbitrary portion having a distance of about 22 to 45 mm, more preferably about 20 to 30 mm from the distal end of the insertion tube main body 40a, and the bending angle is preferably 0 to 95 °, more preferably 30 to 30 mm. 70 °.

In each of the above-described embodiments, the connection portion 43 is integrally formed at the rear end portion of the insertion tube main body 40a. However, the connection portion 43 may be a separate body. An example is shown in FIG.
The insertion tube main body 40a and the connection portion 43 are prepared separately in advance, but the rear end portion 47 of the insertion tube main body 40a is inserted into the recessed portion 48 formed at the distal end portion of the connection portion 43, for example, adhesive, welding It joins by appropriate means, such as. Thus, when the insertion tube main body 40a and the connection part 43 are made into a different body, it is preferable to form the connection part 43 with a rigid synthetic resin. In the case of this embodiment, the stopper portion 44 is formed at the tip of the connection portion 43.

  As the bodily fluid leakage preventing agent to be injected and loaded into the body cavity such as the mouth, nose, and ear of the corpse by the corpse treatment apparatus of the present invention described above, various conventionally known jelly-like bodily fluid leakage preventing agents can be used. Preferably, a viscous liquid containing a liquid nonionic surfactant (A) which is exothermic when mixed with water and quickly soluble in water, and a specific dispersion stabilizer (B) which is dissolved in the liquid is described below. It is desirable to use an oil jelly-like body fluid leakage preventing agent in which the superabsorbent resin powder (C) is dispersed in the base. When such a bodily fluid leakage prevention agent is used, the heat-absorbing speed of the superabsorbent resin powder (C) is increased by the exothermic action of the nonionic surfactant (A) when in contact with bodily fluids. It can quickly absorb and swell body fluid to solidify into a solid jelly with no fluidity, effectively preventing body fluid leakage.

  Nonionic surfactant (A) which is liquid at room temperature includes coconut oil fatty acid monoethanolamide, coconut oil fatty acid diethanolamide 1: 1 type, coconut oil fatty acid diethanolamide 1: 2 type, polyoxyethylene coconut oil fatty acid monoethanol Amide, lauric acid diethanolamide, polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene higher alcohol ether, polyethylene glycol (average molecular weight of polymerization degree 600 or less), polyoxyethylene polyoxypropylene glycol (polypropylene glycol) Pluronic-type nonionic surfactant obtained by adding ethylene oxide to polyoxyethylene alkyl (alkyl group having 12 to 14 carbon atoms) ether (addition mole number of ethylene oxide: 7 to 12 moles) Polyoxyethylene alkyl ether and the like, sorbitan fatty acid esters, surfactants such as polyoxyethylene sorbitan fatty acid esters and the like, may be used in combination either alone or in combination. Among these nonionic surfactants (A), liquid polyethylene glycol (average molecular weight of polymerization degree is about 200 to 600) is preferable.

  These liquid nonionic surfactants (A), particularly liquid polyethylene glycol (average molecular weight of polymerization degree is about 200 to 600) are dispersion stabilizers (B) described below, particularly polyalkylene oxide thermoplastic nonions. The mold water-absorbing resin powder can be easily dissolved at a low temperature (about 30 ° C. to 50 ° C.), and when mixed with water, as shown in the following test examples, it generates heat when it comes into contact with water. In addition, the water temperature rises (about 10 ° C to 12 ° C rises), and since it is a surfactant, it has good compatibility with water and can be easily mixed and dissolved with water to increase the water absorption rate of the superabsorbent resin as described above. It can quickly solidify into a solid jelly with no fluidity to prevent leakage of bodily fluids.

Test example (exothermic temperature measurement test of test material)
Test method:
10 g of each raw material shown in Table 1 was weighed into a 30 ml beaker, and then the exothermic temperature of the mixed solution when 8 g of ion-exchanged water was injected was measured under the following conditions.
Measuring instrument: Temperature sensor for liquid of DATA COLLECTOR manufactured by Anritsu Keiki Co., Ltd.
Room temperature at the time of measurement: 22.3 ° C.
The test results are also shown in Table 1.

上記表１に示すように、液状のノニオン性界面活性剤であるＰＥＧ２００の場合、水と混和すると直ちに発熱し、速やかに水に可溶となり、またその温度レベルをある程度の時間維持できた。これに対して、アルコール系溶剤である無水グリセリン、エチレングリコール、エチルアルコールの場合、水と混和した後に僅かに発熱するが、その温度レベルがかなり低い。このことから、液状のノニオン性界面活性剤であるＰＥＧ２００は、高吸水性樹脂の吸水速度を高め、速やかに流動性の無い固いゼリー状に固化して体液漏出防止を図る体液漏出防止剤の基剤として最適であることがわかる。

As shown in Table 1 above, in the case of PEG200, which is a liquid nonionic surfactant, heat was generated immediately when mixed with water, and it quickly became soluble in water, and the temperature level could be maintained for a certain period of time. In contrast, anhydrous glycerin, ethylene glycol, and ethyl alcohol, which are alcohol solvents, generate a slight amount of heat after being mixed with water, but their temperature level is considerably low. Therefore, PEG200, which is a liquid nonionic surfactant, is a body fluid leakage preventing agent that increases the water absorption rate of the highly water-absorbent resin and quickly solidifies into a solid jelly with no fluidity to prevent fluid leakage. It turns out that it is optimal as an agent.

  The content of the nonionic surfactant (A) is preferably about 10 to 85% by mass, more preferably about 20 to 80% by mass, and further preferably about 30 to 70% by mass of the total amount of the body fluid leakage preventing agent. is there. When the content of the nonionic surfactant (A) exceeds 85% by mass, there is no problem with the dispersibility of the superabsorbent resin powder, but it is difficult to form a jelly and the liquid state is an aqueous solution. It is not preferable because it is close to. On the other hand, if the content of the nonionic surfactant (A) is too low, it is difficult to obtain a good jelly state. Further, in addition to the above-described nonionic surfactant (A), an anionic surfactant can be contained as necessary in a quantitative ratio that does not impair the above-described effects.

  The dispersion stabilizer (B) is for maintaining a uniform dispersion state of the highly water-absorbent resin powder, and can absorb various electrolyte aqueous solutions and is hardly affected by the electrolyte concentration. From thermoplastic nonionic water-absorbent resin, carboxyvinyl polymer of acrylic acid copolymer, carboxyvinyl polymer / alkali neutralizer of acrylic acid copolymer, lipophilic smectite, synthetic hectorite, natural hectorite, and bentonite At least one selected from the group consisting of Among these dispersion stabilizers (B), a polyalkylene oxide-based thermoplastic nonionic water-absorbing resin is preferable, and this resin can absorb various aqueous electrolyte solutions and is hardly affected by the electrolyte concentration. Absorption of alkaline aqueous solution is possible.

  The content of the dispersion stabilizer (B) is preferably about 0.5 to 40% by mass, more preferably about 1 to 30% by mass, based on the total amount of the body fluid leakage preventing agent. If the content of the dispersion stabilizer (B) is too low, it becomes difficult to maintain the uniform dispersibility of the superabsorbent resin powder. On the other hand, even if it is added in a large amount exceeding 40% by mass, the effect is further improved. Is not preferable from the viewpoint of economy.

  As the superabsorbent resin powder (C), conventionally known superabsorbent resin powders can be used, and are not limited to specific ones. Among them, polyvinyl acrylate, polyacrylate, Alginate, cross-linked acrylic acid graft copolymer, copolymer of vinyl alcohol and polyacrylic acid, polyethylene glycol polymer, polyacrylamide resin, polyacrylic maleic acid copolymer, polyethylene oxide polymer, and poly At least one selected from the group consisting of alginate 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.
In addition, the content of the superabsorbent resin powder (C) must be a necessary amount to immediately absorb and expand the body fluid from the body without leaking from the body cavity to create a non-flowable gel. The content of the superabsorbent resin powder is preferably about 5 to 50% by mass, more preferably about 15 to 35% by mass, based on the total amount of the body fluid leakage preventing agent.

  Further, the body fluid leakage preventing agent is an alcohol-based organic solvent (D) such as ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, glycerin, methyl alcohol, ethyl alcohol, isopropyl alcohol, etc., which is further soluble in water as an auxiliary solvent. Viscosity adjustment is easy by containing either or both of thickeners (E) such as sodium carboxymethylcellulose, carboxymethylcellulose, methylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, sora gum, sodium alginate, etc. for improving fluidity Thus, fluidity can be improved, and even a narrow body cavity such as a throat can be injected and loaded more smoothly. Furthermore, by containing at least one selected from the group consisting of bactericides, fungicides / antiseptics, deodorants and fragrances, these desired effects can also be exhibited.

The viscosity of the body fluid leakage preventing agent containing the above components is preferably about 6,000 to 50,000 cPs, more preferably about 10,000 to 40,000 cPs in order to have good fluidity. is there.
In addition, the viscosity here uses a viscometer (manufactured by Brookfield, USA, “Digital Viscometer” model: DV-1 +), spindle No. Although it is the value measured on the measurement conditions of 07, rotation speed: 20rpm, use body fluid leakage prevention agent temperature: 20 degreeC, it is not limited to this, What is necessary is just the measurement value measured on the same conditions.
The lower the content of the nonionic surfactant (A), the higher the content of the superabsorbent resin powder (C), the shorter the time in which the bodily fluid leakage preventing agent becomes jelly-like, and the liquid Therefore, by adjusting the amount of these components, it is possible to adjust the liquid viscosity according to the time required for the jelly and the desired application (application site).

  The amount of the body fluid leakage preventing agent injected and filled into the body cavity can be appropriately set according to the application site. In addition, depending on the water absorption performance of the superabsorbent resin contained in the oil jelly-like body fluid leakage preventing agent, 3,000 ml of water is gelled and has a water absorption capability to prevent leakage of body fluid from inside the body cavity. It may be to some extent, generally 5 to 60 g is preferable, and more preferably 10 to 40 g. For example, the filling amount of the bodily fluid leakage preventive agent (containing 5 to 50% by mass of the superabsorbent resin) to be injected into the throat from the nostril of the corpse is preferably about 8 to 40 g, more preferably about 10 to 25 g. When the injection amount of the oil jelly-like body fluid leakage preventing agent is too large, the injection device becomes large, so that it is difficult to handle and the cost increases. On the other hand, when the injection amount is too small, it is difficult to harden the body fluid in a gel state, and there is a risk of the body fluid leaking out, which is not preferable.
