Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bodily fluid leakage prevention device that is loaded into a hole of a corpse in order to prevent humor leakage from the corpse.
[0002]
[Prior art]
The human body may leak bodily fluids such as gastric fluid, lung fluid, and ascites after death. For this reason, for example, in hospitals, after confirming death, gauze, absorbent cotton, etc. are loaded into the mouth, nose, etc. of the corpse to prevent leakage of bodily fluids.
[0003]
It is also known to load a highly water-absorbing resin powder into the mouth, nose, ears, throat and the like.
[0004]
For example, in JP-A-7-265367, it is known to use a water-absorbent resin powder containing stabilized chlorine dioxide as a powder in the throat, wrapped in a water-soluble sheet in the ear and nostrils.
[0005]
Further, as disclosed in JP-A-10-298001, it is known to use a syringe to load a superabsorbent resin powder into the mouth, nose and ears.
[0006]
[Problems to be solved by the invention]
In the method of loading gauze, cotton wool, etc. to the mouth, nose, etc. of the corpse that is generally performed, if there are a lot of leaking body fluids, gauze, cotton wool, etc. are insufficient and may leak outside. Yes. Moreover, it is necessary to replace with new gauze, absorbent cotton or the like, which is not only troublesome, but there is a risk that pathogens may be transmitted through the body fluid, and there is a problem that a bad odor of the leaked body fluid remains in the vicinity at the time of replacement.
[0007]
Even if an attempt is made to load the resin powder into the throat part as disclosed in JP-A-7-265367, it is difficult to load the resin powder up to the throat part without means for loading.
[0008]
Japanese Patent Application Laid-Open No. 10-298001 describes the use of a highly water-absorbing polymer fine powder in order to ensure fluidity as much as possible. However, if it is put in the entrance part of the nostril or ear canal, it can be filled even if the fine powder is put in a cylinder such as a syringe as in this publication, but it cannot be filled to the back. In particular, if the cylinder is moved rapidly in order to fill the interior, only the fine powder from the tip is scattered, and the body remains only dirty.
[0009]
That is, in the method of filling the body with the powder as it is as in JP-A-7-265367 and JP-A-10-298001, the density of the powder itself is increased even if the powder is pressed, and the inside of the filling device is smoothed. Therefore, it is difficult to fill even if a cylinder is used. In addition, since the powder that pops out diffuses, it is difficult to fix the powder and fix the powder where it is desired to be plugged, and in some cases, it may go out of the body and stain the periphery of the body. Further, when the powder is directly loaded on the corpse, there is a possibility that fine powder may spill out or the gel may dissolve and leak out from the corpse with less body fluid.
[0010]
Since the powder cannot be loaded just as it is, it is not always successful in the actual site, and it is still only a first aid with gauze or cotton wool, and it is strongly desired to realize a body fluid leakage technique replacing gauze or cotton wool.
[0011]
The first object of the present invention is to fill the body with a little liquid added to the body fluid leakage preventive agent, paying attention to the fact that the body fluid leakage cannot be prevented by simply filling the body with the fine powder as it is. Is. In particular, water is added to the body fluid leakage preventing agent during use, but the body fluid leakage preventing agent is maintained in a fine powder state when not in use and is not mixed with moisture.
[0012]
The second object is characterized in that the body fluid leakage preventing agent is smoothly filled by adding moisture to the body fluid leakage preventing agent at the time of filling and filling it using a compressed gas.

[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0026]
FIG. 1 shows an embodiment in which a bodily fluid leakage preventing apparatus according to the present invention is inserted from the nose of a dead body to prevent bodily fluid leakage at the throat. The pressure accumulator 1 contains a jet gas and a liquid inside, and has a jet port 2 at the top. The pressing member 3 includes a pressing portion 4 that presses the ejection port 2, a communication duct 5 that has one end connected to the ejection port 2 and the other end connected to the outside, and a fitting portion 6 that fits in the upper portion of the pressure accumulator. The pressing member 3 is covered with a lid member 7 in order to prevent the pressing portion 4 from being inadvertently pressed.
[0027]
The container 8 has a main body 10 containing a body fluid leakage preventing powder 9 and an elongated capsule shape having an inlet portion 11 and an outlet portion 12 at both ends of the main body 10. A sponge-like stopper 13 as a first temporary sealing mechanism is disposed at the inlet 11 of the container and is connected to the other end of the communication duct 5. The spongy plug 13 prevents the bodily fluid leakage prevention powder 9 from flowing out to the communication duct 5 and the jet outlet 2 when the inlet 11 of the container 8 is directed downward, and allows the gas in the pressure accumulator 1 to pass therethrough. It is a body. The stopper 13 may be removed and brought into the container body 10 when the gas in the pressure accumulator 1 passes. In this embodiment, a spongy plug is used because it is easy to handle. However, the present invention is not limited to a sponge plug, and any function may be used as long as the above function is achieved. For example, a thin film or a one-way valve may be used.
[0028]
Between the inlet 12 of the container 8 and the communication duct 5. In order to ensure the degree of freedom of the direction of the container 8 relative to the pressure accumulator 1, a bellows tube 14 is provided.
[0029]
The outlet portion 12 of the container 8 is formed in a tapered shape, and a protective cap 15 made of rubber is provided on the tapered portion to prevent the body fluid leakage preventing powder 9 from flowing out when the outlet portion 12 of the container 8 is directed downward. It is covered.
[0030]
The supply pipe is composed of an elongated pipe-like insertion pipe 16 inserted into the nose, and the intermediate portion 16a rotates once. A connecting portion 17 with the outlet portion 12 of the container is formed at one end, and an injection hole 18 is formed at the other end. The connecting portion 17 is formed with an extrapolation tube portion 19 that is extrapolated to the outlet portion 12 of the container 8, and a packing 20 is disposed on the step portion of the extratubation tube portion 19. A groove 19a is provided to facilitate alignment. The groove 19 a may be provided at the outlet portion 12 of the container 8.
[0031]
At the time of use, the protective cap 15 of the outlet portion 12 of the container 8 is removed, and the outlet portion 12 is inserted into the outer insertion portion 19 of the insertion tube 16 until the tip of the insertion portion 16 contacts the packing 20. Thereby, the container 8 and the insertion tube 16 are connected. Since the protective cap 15 is removed, the body fluid leakage preventing powder 9 in the container 12 flows into the insertion tube 16 when the outlet 12 of the container 8 is directed downward, but the intermediate portion 16a rotates once. The body fluid leakage preventing powder 9 does not flow out from the insertion tube 16 to the outside.
[0032]
In this embodiment, the second temporary sealing mechanism is constituted by the protective cap 15 when the container 8 and the insertion tube 16 are not connected, and by the one-turn portion 16a of the insertion tube 16 when the container 8 is connected. The configuration of the second temporary sealing mechanism is not limited to this embodiment. For example, a sponge-like stopper 13 may be provided similarly to the inlet portion 11, or a thin film and a one-way valve may be provided. When such a stopper is provided, the bodily fluid leakage prevention powder 9 does not flow out carelessly, and therefore it is not necessary to provide the part 16a rotated once in the middle part of the insertion tube 16. In addition, instead of connecting the container 8 and the insertion tube 16 at the time of use as in this embodiment, a configuration in which the container 8 and the insertion tube 16 are integrally formed may be prepared.
[0033]
As shown in FIG. 2, the injection hole 18 formed at the other end of the insertion tube 16 is tapered so as not to damage the inner wall of the nostril. The injection hole 18 includes a first injection hole 18a formed at the tip and four second sealing holes 18b formed at the side portions. The second injection hole 18b is a circular hole in which two holes facing each other are provided 90 degrees out of phase. The first injection hole 18a and the second injection hole 18b are provided so that the bodily fluid leakage preventing powder 9 is introduced from the other injection hole into the throat even when one of the injection holes is closed.
[0034]
Therefore, as long as this purpose is not deviated, the number of the second injection holes 18b is not limited to four, and the position and shape are not limited to the above embodiment.
[0035]
A mark 21 is provided in the middle of the insertion tube 16. This mark 21 is a mark indicating whether or not the injection hole 18 of the insertion tube 16 has reached the throat.
[0036]
If the inner diameter of the insertion tube 16 is large, the body fluid leakage preventing powder 9 tends to flow, but it becomes difficult to insert the insertion tube 16 into the nostril. If the inner diameter is small, the insertion tube 16 can be easily inserted into the nostril. Therefore, as a result of testing tubes of various diameters, the inner diameter of the insertion tube was 2 to 8 millimeters, preferably 4 to 6 millimeters. In that case, the outer diameter was good up to the inner diameter plus 1 mm.
[0037]
The ratio of the jet gas and the liquid put into the pressure accumulating body 1 is that the body fluid leakage preventing agent 9 does not flow smoothly through the insertion tube 16 if the amount of liquid is too small. There was a case of leakage from the nostril without gelation in the throat. If there is too much liquid, gelation may proceed in the container 8 or the insertion tube 16 and clogging may occur in the insertion tube 16. As a result of the test, the volume ratio of the jet gas and the liquid was 1: 1 to 5 and particularly the ratio of 1.5 to 3 was good.
[0038]
Moreover, there is a concern about bacterial contamination from the corpse, and it is preferable to introduce a bactericidal agent together with the body fluid leakage preventing agent 9. In the present example, as a result of testing, it was preferable that the liquid had a sterilizing liquid and water in a volume ratio of 1: 2 to 6.
[0039]
As the body fluid leakage preventing agent 9, a highly water-absorbing polymer is known. In the present invention, this known material may be used. However, the use of amphiphilic gel powders or fine particles, especially amphiphilic gel powders mainly composed of dimethylacrylamide, not only absorbs body fluids and gels, but also against body fluids including gastric juice and bile. The gel state could be maintained.
[0040]
When the discharge pressure of the jet gas is weak, the bodily fluid leakage preventing agent is not introduced into the corpse, and conversely, when the pressure is high, the gas is blown out from the nostril and there are cases where the bodily fluid leaks. Therefore, it is necessary to adjust the gas discharge pressure, but the supply speed of the body fluid leakage preventing agent is set to 2 to 10 ml / sec. In particular, when adjusted to 4 to 8 ml / sec, the body fluid leakage preventing agent was smoothly supplied from the nostril to the throat, and there was no leakage of gas or body fluid.
[0041]
The operation of this embodiment will be described.
[0042]
The outlet portion 12 of the container 8 in which the pressure accumulator 1 is integrated is directed upward, the body fluid leakage preventing agent 9 in the container 8 is maintained so as not to leak, and the protective cap 15 is removed. Then, the outer insertion tube portion 19 of the insertion tube 16 is connected to the outlet portion 12. Thereafter, the insertion tube 16 is inserted through the nostril of the corpse. In some cases, a lubricant such as oil, jelly, or glycerin may be applied to the insertion tube 16 to facilitate insertion.
[0043]
Insertion is stopped when the mark 21 of the insertion tube 16 reaches the tip of the nose. When the lid member 7 of the pressure accumulator 1 is removed and the pressing portion 4 is pushed, the gas and liquid of the pressure accumulator 1 are sent to the container 8 containing the bodily fluid leakage preventing agent 9, and these mixtures are inserted into the insertion tube 16. It is injected into the throat through the injection hole 18 at the tip. Since it is injected from the first injection hole 18a at the tip and the second injection hole 18b at the side, even if any of the injection holes is clogged or difficult to come out, it can be concentrated quickly without being scattered in the throat. be introduced.
[0044]
FIG. 3 shows the insertion tube 16 formed with a stopper 22 instead of the mark 21. If the stopper 22 is used, the insertion position can be prevented from being varied by the inserter, and the insertion tube 16 is supported by the nose, and the position of the insertion tube 16 is stabilized. Therefore, when the body fluid leakage preventing agent 9 is sealed, the operation is easy. Yes, anyone can handle it the same way.
[0045]
Dimethyl ether, butane, propane, nitrogen, carbon dioxide, etc. are used as the compressed gas to be put into the pressure accumulator 1.
[0046]
Although the present invention has been described in the embodiment in which it is introduced through the nostril and the throat is sealed, the present invention may be applied to the oral cavity of the corpse, the nostril itself, the ear canal, the urethra, the anus, and the female vagina. Moreover, you may apply also to the wound and opening part of a corpse after an accident or an operation.
[0047]
【The invention's effect】
In the present invention, a liquid is added to the bodily fluid leakage preventive agent so that the body is filled, and in particular, water can be added to the bodily fluid leakage preventing agent during use. It is held in a fine powder state so that it does not mix with moisture. Therefore, when not in use, moisture and body fluid leakage preventive agent do not mix inadvertently, and during use, body fluid leakage prevention agent can be injected into the body with moisture and compressed gas, so body fluid leakage prevention agent can smoothly flow through the supply pipe. It flows and is introduced into the body.
[0048]
When the tip of the insertion tube is tapered, the body is not damaged at the tip when inserted into the body, and injection holes are formed in the front and side of the insertion tube. Can also be injected.
[0049]
Since the mark is provided in the portion corresponding to the length at which the distal end portion of the insertion tube reaches the throat portion, variation in insertion work by the operator can be prevented. When the stopper is provided, the insertion tube and the container are stably held in the nostrils, so that the work can be stably performed when the body fluid leakage preventing agent is injected using the pressure accumulator.
[0050]
When the amphiphilic gel powder is used as a body fluid leakage preventing agent, the amphiphilic gel powder introduced into the corpse can be gelled by the body fluid to prevent body fluid leakage and is insoluble in water. Even if the corpse is left unattended, the gel state can be maintained without dissolving against body fluids and moisture.
