[0002]

2. Description of the Related Art A patient who is temporarily or permanently unable to pass defecation from the anus has a hole in the abdomen of the human body, that is, an artificial anus, which is placed in the human body so that defecation can be performed from the artificial anus. A pipe or the like is provided. Then, as one of the minimum requirements for this patient to return to society, an ostomy appliance that accommodates defecation from an ostomy is used.
This colostomy device is provided with a bag-shaped container having a defecation inlet, and can be attached to a human body with an adhesive tape or the like so that the defecation inlet is located in the colostomy. However, if you defecate on an ostomy appliance,
A bad odor such as defecation odor or urine odor leaked from the gap between the colostomy device and the human body and was released into the living space through the clothes, which could cause discomfort to the patient and others.

In order to solve this, the applicant of the present application first applied for a deodorizing device connectable to a device requiring deodorizing (Japanese Patent Application No. 6-136190). This deodorizing device has a substantially cylindrical shape and has a connecting portion at at least one end thereof and a gas passage inside, and the gas passage is formed to have a cross-sectional shape substantially the same as the gas passage cross section of the case. The deodorizing filter thus arranged is provided, and gas is taken in from one end and passed through the deodorizing filter to be discharged from the other end of the case.

By the way, the deodorizing technology has hitherto been decomposed (for example, oxidative decomposition, biological decomposition, etc.) and adsorbed (for example,
Technical development has been carried out mainly for industrial applications such as physical adsorption method, chemical adsorption method, etc.), but in recent years, it has also been used for appliances and the like necessary for daily life.

For the decomposition, there are means such as ozone decomposition and combustion oxidative decomposition, but the "latest adsorption technology (Comprehensive Technology Center)"
As also introduced in the article, since a device for generating ozone, heating, etc. is required, there is a problem that it is too large for an ordinary person to carry.

The physical adsorption method, which is one of the adsorption methods, has activated carbon as a typical means thereof. As described in "Activated carbon (Kodansha)", the activated carbon is hydrogen sulfide or mercaptan. Although it has excellent adsorption performance for sulfur odors, it has a disadvantage for adsorption of low molecular weight gases such as ammonia. Further, as another means of the physical adsorption method, there is a composition in which a metal oxide (for example, zinc oxide, copper oxide, etc.) is contained in an inorganic substance of a cordierite composition, and a metal chloride is combined. The substance has an effect of deodorizing both ammonia and hydrogen sulfide.

Further, at a portion of the colostomy device 1 which is filled with the defecation gas Y, a connecting cylinder portion 13 which is connected to the deodorizing device 2 and guides the defecation gas Y to the deodorizing device 2 is formed in a substantially cylindrical shape. In addition, here, the diameter of the opening end face of the connecting tube portion 13 is set to about 8 mm.

The deodorizing device 2 has a substantially annular base 22 having a gas intake port 21 in the substantially center thereof, and a substantially circular case provided above the base 22 so as to form five chambers therein. A main body 23 and a case having a substantially flat box shape are formed, and a deodorizing filter 24 is arranged inside the case, so that the gas taken in from the gas inlet 21 is transferred from the first chamber 25 to the second chamber 26 and the third chamber. The chamber 27, the fourth chamber 28, and the fifth chamber 29 are advanced to the outside through a gas discharge port 30 provided in the upper portion of the fifth chamber 29. The base 22 and the case body 23 are coupled to each other by ultrasonic welding or the like. In addition, the arrow in FIG. 1 has shown the direction which gas advances.

The deodorant filter 24 is made by kneading zinc oxide in cordierite composition and firing it with zinc chloride added, and is filled inside the case body 23. In addition,
Here, the deodorizing filter 24 is set to about 1.5 cc.

Between the gas inlet 21 and the first chamber 25,
A porous member 31 is arranged to prevent the deodorant filter 24 from falling off. The porous member 31 has a function of preventing the deodorizing filter 24 from falling off, and when the deodorizing filter 24 is partially or wholly composed of a large number of powders or an aggregate of particles, it is powdery. It has a function of preventing the body or granular body from coming out of the case body 23, and enables the deodorant filter 24 to be used for a long time.

On the lower surface of the base 22, there is provided a connecting portion 32 which has an opening at a position corresponding to the gas intake port 21 and which is formed in a substantially annular shape by an adhesive material. The connecting part 32 is attached to the colostomy device 1 when the connection tube part 13 is fitted into the gas intake port 21, and the defecation gas Y is discharged from the gap between the colostomy device 1 and the case body 23 to the outside. Prevent leaks. Further, the connecting portion 32 is protected by the peeling member 33 having substantially the same shape before being attached to the ostomy appliance 1.

Next, the operation of this embodiment will be described.
The defecation gas Y filling the inside of the colostomy device 1 enters the inside of the deodorizing device 2 from the gas intake port 21 into which the connecting tube portion 13 is inserted, passes through the porous member 31 and the deodorizing filter 24, and becomes a gas.

The gas intake port 21 and the gas discharge port 30 are each formed in a substantially cylindrical shape so as to also serve as a connection part, and one end of the tube 41 is press-fitted to the gas intake port 21 to connect the tube part of the ostomy appliance 1. By connecting the other end of the tube 41 to 13 by press fitting, the defecation gas Y inside the colostomy device 1 is introduced into the deodorizing device 2. Further, another tube 41 can be connected to the gas discharge port 30 if necessary. Reference numeral 42 is a partition for making the gas passage non-linear and partitioning the inside of the case body 23 into a plurality of chambers.

On the outer surface of the case body 23, as shown in FIG. 5, a substantially plate-shaped clip 43 is attached so as to have a gap between the clip body 43 and the case body 23 and the clip 43. The deodorizing device 2 can be attached to clothes or the like by inserting clothes or the like into the space between the deodorizing device 2 and the clothes.

Inside the case main body 23, a porous member 31 is arranged in the vicinity of the gas intake port 21 and in the vicinity of the gas discharge port 30, and the deodorizing filter 24 is filled inside the porous member 31. The deodorant filter 24 is obtained by kneading zinc oxide in the cordierite composition and adding zinc chloride after firing.
It is composed of activated carbon with a particle size of about 3 mm, and each uses about 2.5 cc.

Next, the operation of this embodiment will be described.
The defecation gas Y filling the inside of the colostomy device 1 is connected to the deodorizing device from the gas inlet port 21 via the connecting tubular portion 13 and the tube 41.

As described above, in the present embodiment, as in the first embodiment, the defecation gas Y filling the inside of the colostomy device 1 is discharged to the outside through the deodorizing device 2, so that the colostomy device 1 is It is possible to make it difficult for the user and the people around it to feel uncomfortable due to the odor of the defecation gas Y.

Further, in this embodiment, the gas passage is made non-linear inside the case. Therefore, the dimension in one direction is larger than that of the case where the gas passage is formed in a straight line. Therefore, the overall shape can be reduced.

In this embodiment, the deodorizing device 2 is replaced with a tube.
Since it is possible to connect to the colostomy device 1 via 41, the deodorizing device 2 can be installed at an optimum position.

In this embodiment, the deodorizing device 2 is clipped.
Since it can be held at an appropriate position by 43, for example, at a position where movement of the body is not hindered, it is easy to use.

Next, a sensory test conducted to confirm the deodorizing effect of the first and second embodiments will be described. The sensory test was conducted on the first and second examples and their comparative examples. As a comparative example, a commercially available stoma filter in which activated carbon is impregnated on a foamed urethane sheet is approximately disc-shaped (diameter 15 mm, thickness 3 mm).
And was attached to the connecting tube portion 13 of the colostomy device 1.

The method of the sensory test is as follows.
(1) First, about 50c of defecation X is placed inside the colostomy device 1.
c House. (2) Next, the defecation inlet 11 is sealed with a Teflon sheet so that the internal space of the colostomy device 1 is about 100 cc. (3) Next, when the artificial anus brace 1 is lightly pressed so that the defecation gas Y filling the inside passes through the deodorizing device 2 and is released to the outside, when the space inside the colostomy 1 is reduced to some extent, The Teflon sheet is peeled off, air is introduced so that the internal space of the colostomy device 1 becomes about 100 cc, and the defecation inlet 11 is sealed again with the Teflon sheet. (4) The operation of (3) is repeated. (5) When the operation of (3) is the 10th time, a sensory test of a six-step odor intensity display method is performed by 10 general men and women (referred to as panelists). The distance between the nose of the panel and the gas outlet 30 is about 20 cm.
Evaluate as.

As a result of the sensory test, the average odor intensity was about 0.0 in the first and second examples and 2.0 in the comparative example. Here, the smaller the value of the odor intensity, the closer to odorless it is, and the larger the value, the stronger the odor. The odor intensity of 4 indicates a very strong odor, and the odor intensity of 5 indicates an extremely strong odor.

Therefore, it can be seen that the average odor intensity of the first and second examples is much lower than that of the comparative example and is almost odorless.

Next, a third embodiment of this embodiment will be described with reference to FIG. It should be noted that members having substantially the same functions as those of the first and second embodiments described above are designated by the same reference numerals and description thereof will be omitted.
