Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an amniotic fluid rupture distinguishing pad which can be worn by a pregnant woman to judge the amniotic fluid rupture.

[0002]

2. Description of the Related Art Conventionally, as a method for judging the rupture of amniotic fluid in pregnant women, there are "acidity test method", "hair proof method" , and "vernix testimony" for judging mucus collected from the vagina of pregnant women in hospitals. Method ” and “ dendrite proof method ”are known.

All of these conventional methods are pregnant.
The woman herself could not identify the amniotic fluid rupture,
This is something that must be admitted to a doctor for diagnosis, and
All of the conventional methods for identifying water rupture are at the time when it seems to be water rupture.
It is not reliable unless done within 1 hour. And this
Is most likely to occur from around the 38th week of pregnancy.
However, there are individual differences in the amount of water rupture, and it may be mistaken for urine.
Is also common.

For example, at the time of hospitalization due to threatened abortion or premature labor
And subsequent bleeding, or at rest at home, or even amniotic fluid
When the water ruptures, it becomes an important factor in the life and death of the fetus.
Therefore, in case of water breakage, it is necessary to take emergency measures.
In addition, at the time of outpatient treatment or when there is little amniotic fluid leakage,
Definitive diagnosis of water becomes difficult. And the rupture of the pregnant woman before delivery
Even in water diagnosis, in the case of small amount of water disruption with few subjective symptoms
Is, patients who do not visit also rather high, even after the rupture of the membranes as was admitted 24
Some patients have passed the time, and moreover, pregnant women cannot be seen from remote areas.
If you are hospitalized, spend time preparing for hospitalization, etc.
Often more than 1 hour after, the doctor
And amniotic fluid becomes difficult to identify. Also, after rupture of water, the fetus is placed in the cervix
When the head becomes a plug and the rupture stops, or when the high rupture occurs,
There is no leakage of amniotic fluid at the time of visit, making it difficult for the doctor to diagnose.

Therefore , in any case, for the time being, the hospital
There is a problem that I have to go to a doctor to get medical treatment .

On the other hand, as an apparatus for identifying amniotic fluid rupture,
For example, the one described in Japanese Utility Model Laid-Open No. 3-33604 is available.
It

This is described in Japanese Utility Model Laid-Open No. 3-33604.
The amniotic fluid rupture identification device is a probe made of a transparent material.
A hole into which amniotic fluid can flow near the closed head on one end
The probe is equipped with a pH indicator on the inner or inner cylindrical surface of this probe.
Is provided.

[0008] And, in using this amniotic fluid rupture identification device
Insert the head side near the posterior fornix of the vagina and
Penetrates into the probe through the hole and moves from the head to the other end
Flowing, reacting by contact with pH indicator, pH indicator
The medicine discolors. And to compare with the colorimetric scale
Judge whether amniotic fluid has flown out due to water rupture.

[0009]

[Problems that the Invention is to provide a method of identifying traditional amniotic fluid, none of which can be pregnant women themselves to distinguish the rupture of the amniotic fluid, either case must undergo a doctor's clinic to go to anyway hospital We have problems.

Further , the above-mentioned Japanese Utility Model Publication No. 3-33604.
According to the amniotic fluid rupture identification device described in,
Although it is possible to identify the rupture of water, the amniotic fluid identification device is inserted in the vagina.
Must be input, resistance to the use by such as the use discomfort
There is a sensation, and if used incorrectly, it may scratch or damage the vaginal wall.
It may induce water and cannot be used easily. Furthermore
In addition, in order to distinguish the water rupture, the probe should be
Has to be inserted into the
There is no subjective symptom of water rupture while discrimination cost increases.
In some cases, it may be necessary to leave the broken water as it is without performing discrimination.
There is Also, insert the probe into the vagina and measure the pH.
To determine the pH of the cervical mucus in the uterus
Will cause erroneous judgment.

Further , a head is provided on one end side with a transparent material.
Form a double-digit probe and place a pH indicator inside the probe.
Therefore, there is a limit to the improvement of manufacturing and the manufacturing cost increases.
I have a problem to do.

The present invention has been made in view of the above problems, and a pregnant woman can easily and inexpensively immediately know the state of water rupture by wearing it in the same manner as a sanitary pad, and can be treated by a doctor. It shall be the object of providing a membrane rupture discrimination pad amniotic fluid capable sake of accurately also.

[0013]

The amniotic fluid rupture discrimination pad of the present invention is an absorbent pad having an opening capable of being absorbed on one surface.
The main body is provided with a pH indicator sheet in which an impregnable sheet piece is impregnated with bromthymol blue (BTB) whose color tone changes by contact with amniotic fluid facing the opening .

[0014]

In the amniotic fluid rupture discrimination pad of the present invention, the pH indicator, bromthymol blue, has a discoloration range from yellow to blue at pH 6.0 to pH 7.6, and generally the pH in the vagina is 3. due to its self-cleaning action. It is maintained at about 4 to 4.5, and amniotic fluid has a pH of 7.5.
Since pH is 8.4, it contains bromthymol blue.
Capable of absorbing pH indicator sheet impregnated in dipping sheet pieces
Since it is provided on the absorbent pad body facing the opening, it can be used by pregnant women.
Just by wearing it like a physical pad, the amniotic fluid absorbed by the absorbent pad body will cause the pH indicator sheet to impregnate the bromthymol blue color from yellow to blue, making it easier for pregnant women themselves to break water. It is possible to know immediately at a cheap price <br/>. In addition, the structure is simple and can be manufactured at low cost, so it can be always worn.
Disruption of water is also cheaper.
