Description

  The present invention relates to a deodorizer for a colostomy pouch.

  An artificial anus is applied to the abdomen of a patient whose anus has been removed during surgery such as colorectal cancer. Since the colostomy cannot control defecation, a bag-like defecation pouch is attached to the colostomy so that feces excreted from the colostomy are accommodated in the defecation pouch.

  This defecation pouch is affixed to the abdomen and attached to the artificial anus. By integrating the defecation pouch with the human body, there is no hindrance to activities in daily life, and social recovery is facilitated.

  However, even if the defecation pouch is formed in a sealed bag shape, it is difficult to confine the defecation odor in the defecation pouch, and there is a possibility that the defecation odor leaks from the connection site between the artificial anus and the defecation pouch.

  If the odor leaks from the defecation pouch in this way, it will be released into the living space through clothes, causing discomfort to the people around it, which will be a mental burden on the surroundings, and the colostomy patient will return to society It was a big hindrance to doing.

  So far, the deodorant pouch has an exhaust hole and a deodorant is attached to the exhaust hole, and the deodorant is deodorized by exhausting the deodorizer through the deodorizer through the deodorizer. Has been proposed (see, for example, Patent Documents 1 and 2).

It is a schematic explanatory drawing which shows the test apparatus used in the Example.

  Hereinafter, the form for carrying out the invention will be given and the deodorizer for colostomy pouch of the present invention (hereinafter simply referred to as “deodorizer”) will be described in more detail.

  Fig.1 (a) is a schematic perspective view which shows the deodorizing tool of one Embodiment of this invention, FIG.1 (b) is a schematic cross-sectional enlarged view.

  As shown in FIGS. 1 (a) and 1 (b), the deodorizer 1 of the present embodiment is attached to the exhaust hole of a defecation pouch attached to the colostomy. And it is the molded object 2 which carry | supported the catalyst 4 which has a metal oxide as a main component on the porous mat 3, or is provided with the said molded object at least.

As the porous mat 3, a thermoplastic resin nonwoven fabric or foam can be used. As the nonwoven fabric of thermoplastic resin, any nonwoven fabric of thermoplastic resin having air permeability can be used without particular limitation. Examples of these include non-woven fabrics made of thermoplastic resin whose material is nylon fiber, polypropylene fiber, polyester fiber, polyolefin fiber, rayon fiber or the like. In addition, although the air flow rate of the nonwoven fabric of thermoplastic resin can be adjusted with the fabric weight of a fiber and can be suitably determined according to the specification of the deodorizer 1, it is usually 10 to 30 g / m ² . The amount is desirable.

As the foam, any foam can be used as long as it is a foam that communicates with air and has air permeability. Examples thereof include urethane foam, polyethylene foam, and activated carbon foam in which activated carbon is applied to urethane foam. A density of 10 to 30 g / m ² is desirable. As the activated carbon foam obtained by impregnating activated carbon with urethane foam, for example, Kuraray Chemical Co., Ltd., Kurasheet (registered trademark) is available.

  The catalyst 4 is a catalyst 4 having a metal oxide as a main component that exhibits a deodorizing function at room temperature (5 to 35 ° C.). Examples of the main component metal oxide include copper oxide, manganese dioxide, and four. Examples thereof include tricobalt oxide.

  The odor generated from the stool includes the odor of sulfur-based gas such as hydrogen sulfide and methyl mercaptan and the odor of nitrogen-based gas such as ammonia and trimethylamine. Of these odors, manganese dioxide is suitable as a metal oxide that deodorizes the odor of sulfur-based gas, and copper oxide is suitable as a metal oxide that deodorizes the odor of nitrogen-based gas.

  Therefore, it is desirable that the catalyst 4 contains at least one of copper oxide and manganese dioxide. Moreover, these metal oxides may be used individually by 1 type, and may be used in combination of 2 or more types. Moreover, in addition to a metal oxide, non-powdered activated carbon can be blended as a subcomponent. By blending powdered activated carbon, the deodorizing effect can be further improved.

  In addition, other components such as a colorant and a fragrance can be added to the catalyst 4 as necessary, as long as the effects of the present invention are not impaired.

  On the other hand, since the catalyst 4 cannot be fixed to the porous mat 3 and formed into the molded body 2 as it is, the catalyst 4 is dispersed in a binder or the like, applied to the porous mat 3 as a slurry, and dried to obtain a filter-like shape. The molded body 2 can be obtained.

  Any binder can be used without particular limitation as long as it does not impair the effects of the present invention. Examples thereof include colloidal silica, acrylic emulsion, vinyl acetate emulsion, and styrene emulsion.

  The molded body 2 can be used as the deodorant tool 1 as it is. However, the molded body 2 can be used with the deodorant tool 1 by attaching a filter-like sheet for adjusting the air flow rate to the surface of the molded body 2. You can also

  Further, the pressure-sensitive adhesive layer 5 can be formed on one surface of the deodorant tool 1. By forming the pressure-sensitive adhesive layer 5, it can be easily attached to and detached from the exhaust hole. When forming the pressure-sensitive adhesive layer 5, it is desirable to form it on the edge of the deodorizer 1 or to use an air-permeable pressure-sensitive adhesive in consideration of air permeability.

  The thickness, size, and shape of the deodorizer 1 can be appropriately determined according to the size, shape, etc. of the exhaust hole of the defecation pouch to be attached. It is desirable that the thickness is 10 mm, more preferably 2 to 4 mm, and the size is about 5 to 30 mm.

  According to such a deodorant tool 1, it is possible to make the deodorizer 1 easy to operate when worn on the human body by maintaining a deodorizing effect, making it compact and thin, and providing flexibility. Can do.

  Hereinafter, the state in which the deodorizer 1 is mounted on the defecation pouch will be described in detail with reference to the drawings.

  Fig.2 (a) is a schematic sectional side view of the defecation pouch in the state where the deodorizing tool of one embodiment of the present invention is attached, and Fig.2 (b) is a schematic front view.

  As shown in FIGS. 2A and 2B, the defecation pouch 6 is, for example, a soft plastic bag, and holds an opening 7 for introducing feces into the interior, and the opening 7. The flange 8 and the opening 7 are provided with an exhaust hole 9 opened on the opposite side of the defecation pouch 6. The flange 8 is joined to the flange of the colostomy portion of the colostomy patient, and is disposed on the upper portion of the defecation pouch 6. Further, the deodorizer 1 is mounted so as to cover the exhaust hole 9 with the adhesive layer 5.

  The exhaust hole 9 is provided at a position above the defecation pouch 6 so as not to overlap the position of the opening 7. By arranging the exhaust holes 9 in this arrangement, it is possible to prevent the deodorizer 1 from being contaminated by the introduced stool.

  FIG. 3 is a schematic cross-sectional view showing an image of deodorizing odors by the deodorizing tool of one embodiment of the present invention.

  The stool 10 introduced from the opening 7 accumulates in the lower part of the defecation pouch 6, and the generated odor in the defecation pouch 6 passes through the deodorizing tool 1 attached to the exhaust hole 9 by pressure of clothing or the like, and at that stage Deodorized and released to the outside.

  As mentioned above, although the deodorizing tool 1 of this invention was demonstrated based on one embodiment, the deodorizing tool 1 of this invention is not limited to said embodiment, In the range which does not deviate from the summary, it is various. It can be changed.

  For example, in the deodorizer 1 having the configuration shown in FIGS. 2A and 2B, the pressure-sensitive adhesive layer 5 is formed on one side and mounted so as to cover the exhaust hole 9. An attachment member for the deodorizer 1 may be provided separately at the outlet of the deodorizer 1 and the deodorizer 1 may be attached by this attachment member.

  For example, as illustrated in FIG. 4, a plastic attachment member 11 having a U-shape is illustrated. In this case, the deodorizer 1 can be mounted by inserting it into the deodorizer 1 from the open side of the attachment member 11.

  FIG. 4 is a schematic view showing an embodiment of an attachment member for mounting the deodorant tool 1.

EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, this invention is not limited to these Examples at all.
<Example 1>
(Production of deodorant tools)
As a catalyst, 80 parts by mass of manganese dioxide with respect to 20 parts by mass of copper oxide was put in a stainless beaker, and 700 parts by mass of ion-exchanged water was added thereto, followed by stirring with a disbar for 20 minutes to prepare a dispersion.

  Next, 1.8 parts by mass of acrylic emulsion (manufactured by DSM Japan Co., Ltd., styrene acrylic resin emulsion) is added to 100 parts by mass of this dispersion, and the mixture is stirred for 10 minutes. A slurry in which the catalyst was dispersed was prepared.

A non-woven fabric made of polypropylene fibers with a basis weight of 20 g / m ² is immersed in this slurry, and then immediately pulled up to remove the excessively adhered slurry, and then dried to a constant weight with a dryer at 80 ° C. Thus, a molded body having a thickness of 3 mm was obtained.

This molded body was cut into a circle having a diameter of 20 mm to produce a deodorant tool. This deodorizer was thin and flexible.
(Deodorization ability test)
The produced deodorant tool was attached to the test apparatus shown in FIG.

  FIG. 5 is a schematic explanatory diagram showing the test apparatus used in the examples.

  First, 3 L of gas whose hydrogen sulfide gas concentration is adjusted to 10 ppm is injected into the odor bag 12 of the test apparatus, and the gas after passing through the deodorizer 1 is positioned downstream of the deodorizer 1. One gas was taken out from the gas outlet 13 and the gas concentration was measured. The gas concentration was measured according to the gas detector tube method (JIS K 0804).

  Under an initial load condition in which the odor bag 12 was filled with 3 L of gas, the hydrogen sulfide gas concentration from the first gas outlet 13 was a low concentration below the detection limit of the detector tube.

Since the suction capacity per one time of the gas detection tube is 100 mL, all the gas in the odor bag 12 is passed through the deodorizer 1 by repeating the suction from the first gas outlet 13 30 times. Also in this maximum load test, the gas concentration of hydrogen sulfide from the first gas outlet 13 was below the detection limit.
<Example 2>
Next, the same deodorizing ability test was conducted for methyl mercaptan.

  The deodorizer 1 produced in Example 1 was attached to the test apparatus of FIG. 5, and 3 L of gas having a methyl mercaptan gas concentration of 2 ppm was injected into the odor bag 12 to start the test.

  Under an initial load condition in which the odor bag 12 is filled with 3 L of gas, the gas concentration from the first gas outlet 13 located on the downstream side of the deodorizer 1 is below the detection limit. Further, in the test of the maximum load after passing 3 L through the deodorizer 1, the gas concentration of methyl mercaptan was below the detection limit.

  From these results, it was confirmed that the deodorizer of the present invention is a thin and highly flexible deodorizer while maintaining a high deodorizing effect.

  In the test apparatus of FIG. 5, the gas before passing through the deodorizer 1 is taken out from the second gas outlet 14 located on the upstream side of the deodorizer 1 and the gas concentration is measured. The gas after passing can be taken out from the first gas outlet 13 located on the downstream side of the deodorizer 1, the gas concentration can be measured, and the deodorization rate can be obtained from each gas concentration.
