Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing apparatus suitable for deodorizing a bad odor generated in an artificial anus, and is used by connecting to the artificial anus.

[0002]

2. Description of the Related Art A colostomy is a device for protecting an opening (called a stoma) formed in the abdominal wall by a surgical operation such as colostomy or ileotomy, and collecting excrement from the abdominal cavity. And is known to accept naturally discharged stools.

As an artificial anus, there is known an artificial anus including a housing having a flange adhered to the skin around the stoma and a bag (referred to as a pouch) attached to the housing. In the colostomy,
The housing is fixed to the abdomen by sticking it with an adhesive layer (a double-sided tape may be used) provided on the surface of the flange. Since the pouch is hermetically sealed so that the odor does not leak outside, the gas from the intestine gradually accumulates in the pouch. Then, when the gas pressure gradually rises and it starts to regurgitate toward the intestine, the patient feels uncomfortable.Therefore, patients using a colostomy conventionally go to the toilet etc. to eliminate discomfort. After making a hole in the pouch with a needle to release the gas, I either closed the hole with tape or replaced the pouch with a new one.

[0004]

However, such degassing and replacement of the pouch are inconvenient, and
The discomfort caused by the gas filling was unbearable to the patient. Then, in order to eliminate the discomfort caused by such an increase in the internal pressure of the pouch, if a hole is made in a part of the pouch and connected to the atmosphere with a flexible tube, the internal pressure of the pouch becomes equal to the atmospheric pressure, so that the gas reverse flow Comfortably,
Natural defecation is performed smoothly, but this situation is a problem because odor leaks to the outside. Therefore, it is considered that a tube is provided with a deodorizer to deodorize, or a pouch is provided with a vent hole with a hydrophobic filter and a deodorant is placed in this portion to deodorize.

It is an object of the present invention to provide a small and lightweight deodorizing device capable of substantially completely eliminating the odor of an artificial anus.

[0006]

In order to solve the above problems, the present invention is a device for deodorizing a bad odor in a pouch connected to a pouch of an artificial anus, comprising a deodorizing filter, the deodorizing filter and the pouch. It comprises a tube connected in communication, a pressure switch and a small solenoid valve arranged on the tube in this order, and a fan mechanism arranged on the downstream side of the deodorizing filter, so that the pressure of gas in the pouch has a predetermined value. It employs a deodorizing device for an artificial anus that activates when the value exceeds a certain value and deodorizes gas forcibly releasing it into the atmosphere. A small battery can be used as a drive source for the deodorizing device.

[0007]

According to the above construction, when the gas pressure in the pouch of the colostomy reaches a predetermined value or more, the pressure switch is turned on, the small solenoid valve that has been closed until then is opened, and the motor of the fan mechanism is driven to drive the fan. Turning the. Then, the gas accumulated in the pouch reaches the deodorizing filter through the tube, is deodorized there, and is forcibly discharged outside by the fan.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic explanatory view of a deodorizing apparatus of the present invention, and FIG. 2 is a view showing a state in which the deodorizing apparatus of FIG. 1 is attached to an artificial anus.

As shown in FIG. 1, the deodorizing device A of the present invention.
Is a deodorizing filter 1, a tube 2 that connects the deodorizing filter 1 and the pouch (P in FIG. 2) to each other, a pressure switch 3 and a small solenoid valve 4 arranged on the tube 2 in this order, and a deodorizing filter. 1 includes a fan mechanism 5 arranged on the downstream side, and when the pressure of the gas in the pouch P exceeds a predetermined value, the small solenoid valve 4 opens to introduce the gas into the deodorizing filter 1 for deodorization. The deodorized gas is forcibly discharged into the atmosphere by the fan mechanism 5. The deodorizing filter 1, the pressure switch 3, the small solenoid valve 4, and the fan mechanism 5 are usually housed in a case 6.

In the deodorizing apparatus A of the present invention, a connector 21 provided at the tip of the tube 2 has an artificial anus O as shown in FIG.
Used by connecting to the pouch P of. Gas from the pouch P passes through the tube 22 and the pressure switch 3 housed in the case 6, and through the tube 23 the small solenoid valve 4
Reach The small solenoid valve 4 is normally closed, and is opened only when the pressure switch 3 is turned on. Therefore, if the pressure switch 3 is turned on when the gas pressure in the pouch P is a certain value (hereinafter, referred to as a predetermined value) or more, it is not necessary to drive the fan mechanism 5 all day, Further, if the predetermined value is set to a gas pressure within a range in which the gas in the pouch does not flow back into the intestine, the patient will not suffer discomfort.

The case 6 is partitioned by a partition wall 61 into a chamber 63 in which the pressure switch 3, the small solenoid valve 4, and the deodorizing filter 1 are accommodated, and a chamber 64 in which the fan mechanism 5 is accommodated. A window 62 for discharging the deodorized gas to the outside is formed.

When the pressure switch 3 is turned on, the small solenoid valve 4 is opened and the fan mechanism 5 consisting of the motor 51 and the fan 52 starts to drive. Then, the gas is introduced into the deodorizing filter 1 through the tube 24, where it is deodorized and enters the chamber 64. Then, the deodorized gas in the chamber 64 is forcibly discharged from the window 62 by the fan 52 to the outside.

The partition of the case 6 is not limited to this embodiment. Further, the fan mechanism 5 may be driven manually.

Any kind of deodorizing filter 1 may be used, but when a deodorizing filter that cannot completely remove the malodor of the artificial anus is used alone, usually, a plurality of different deodorizing filters are connected in series. Stuff used. Those with strong deodorizing ability, such as nickel, cobalt as deodorizing agents,
In the case of a deodorizing filter filled with a composite of halogen compounds of copper and zinc, it may be used alone.

As the deodorizing agent to be filled in the deodorizing filter 1, activated carbon, iron ascorbic acid salt, metal halides, and various other materials can be used.

[0017]

As is apparent from the above description, by adopting the deodorizing apparatus of the present invention, the malodor of the artificial anus can be almost completely deodorized.
