JPH05123324A - Pad for judging amniorrhexis of amniotic fluid - Google Patents

Abstract

PURPOSE:To tell the amniorrhexis of amniotic fluid by installing a pad to a pregnant woman similarly to a sanitary pad. CONSTITUTION:A pH indicator sheet 6 having an impregnating sheet piece 7 impregnated with a bromothymol blue(BTB) the color tone of which is changed by the contact with the waters is provided. At amniorrhexis of amniotic fluid, thus, an absorptive pad body absorbs the fluid to change the color of the pH indicator sheet, and a pregnant woman herself can immediately tell the amniorrhexis.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an amniotic fluid rupture discrimination 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, "acidity test method", "hair proof method", "vernix proof method" for mucus collected from the vagina of pregnant women in hospitals, etc. A "dendrite proof method" is known.

[0003]

In all of the conventional methods, the pregnant woman cannot discriminate the amniotic fluid rupture by the pregnant woman, so that she cannot go to the hospital or be admitted to the hospital for diagnosis by a doctor.
Any discrimination of water rupture is not reliable unless it is done within 1 hour from the time when it is considered to be water rupture. For example, bleeding after admission due to threatened abortion, premature labor, or at rest at home,
In addition, when amniotic fluid ruptures, it becomes an important factor for life and death of the fetus, but definitive diagnosis of rupture of the amniotic fluid becomes difficult at the time of visit to the outpatient clinic or when amniotic fluid leakage is small. In the diagnosis of rupture of pregnant women before parturition, many patients do not come to the hospital if there are few symptomatic ruptures with few subjective symptoms, and there are patients who have visited the hospital 24 hours after the rupture. In this case, it often takes time to prepare for hospitalization, etc., and more than 1 hour has passed since the water rupture, making it difficult for a doctor to distinguish cervical mucus from amniotic fluid. Also, after the water broke,
If the head of the fetus plugs the uterine ostium and the rupture of the fluid stops, or if the rupture of the fetus is high, there is no leakage of amniotic fluid at the time of visit, making it difficult for the doctor to diagnose. Furthermore, pregnant women are most likely to rupture around the 38th week of pregnancy, but there are individual differences in the amount of rupture, which is often mistaken for urine, and in the case of rupture, emergency treatment is required. . Therefore, in any case, there was a problem that the doctor had to go to the hospital for the time being.

The present invention has been made in view of the above-mentioned problems, and a pregnant woman can immediately know the state of water rupture by wearing it in the same manner as a sanitary pad, and is also suitable for medical treatment by a doctor. The purpose of the present invention is to provide an amniotic fluid rupture discrimination pad.

[0005]

The amniotic fluid rupture discrimination pad of the present invention has a pH obtained by impregnating an impregnable sheet piece with bromthymol blue (BTB) whose color tone changes due to contact with amniotic fluid.
It is equipped with an indicator sheet.

[0006]

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 the pH in the vagina is generally 3. It is kept at about 4 to 4.5, and amniotic fluid has a pH of 7.5.
Since the pH is 8.4, the bromine thyme blue is discolored from yellow to blue by the amniotic fluid absorbed by the pH indicator pad body due to the water rupture, and the pregnant woman can immediately know the water rupture.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the amniotic fluid rupture discrimination pad of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes an absorbent pad main body, which is an absorbent body 2 in which cotton-like pulp is laminated, a non-woven fabric 3 wrapping the absorbent body 2 and superposed on the lower surface thereof, from the lower surface of the non-woven fabric 3 to both side surfaces and upper surface thereof. It is composed of a waterproof laminated paper 4 which is partially wrapped to leave the central portion, and a non-woven fabric 5 which is wrapped around the outer side of the laminated paper 4 and is laminated on the lower surface.

[0009] 6 is a sheet piece 7 made of paper cotton or cloth, PH
A pH indicator sheet impregnated with bromthymol blue (hereinafter referred to as BTB) which is an indicator, and a width along the length direction of the pad body 1 between the central portion of the upper surface of the nonwoven fabric 3 of the pad body 1 and the nonwoven fabric 5 One 50 mm sheet piece 7 or 2 to 4 thin sheet pieces 7 having a width of 0.5 cm to 1.5 cm are inserted in parallel.

In the production, the absorbent body 2 made of laminated cotton-like pulp is wrapped with a non-woven fabric 3, the non-woven fabric 3 is overlaid with a pH indicator sheet 6 and the whole is squeezed with a press roller, and then the pH is adjusted.
The whole of the indicator sheet 6 is wrapped with the laminated paper 4 so as to leave the portion, and the whole is further wrapped with the non-woven fabric 5, both ends in the length direction are heat-sealed, and the lower surface has a width of 3 mm and a length of 60.
mm shift prevention adhesives are applied in two rows at intervals of 25 mm, and the release paper 8 is pressure-bonded to the adhesive surface.

The pH indicator BTB has the following structural formula, and the color change range is from pH 6.0 (yellow) to PH7.6 (blue).

[0012]

[Chemical 1]

BT with which the PH indicator sheet 6 is impregnated
The concentration of B is ^{10mg / m 2 ~1000mg / m 2} .

Next, the operation of this embodiment will be explained by a pregnant woman wearing the sanitary absorbent pad in the same manner.
When the amniotic fluid is absorbed by the absorbent pad body 1 by the membrane rupture,
At the same time, the pH indicator sheet 6 absorbs amniotic fluid and is impregnated with BT
Reacts with B and turns from yellow to blue. Therefore, the water breakage can be immediately known.

[0015]

According to the present invention, when the amniotic fluid is ruptured, the absorbent pad body absorbs the amniotic fluid and the pH indicator sheet is discolored so that the pregnant woman can immediately know the rupture of the fluid, thus treating imminent abortion and premature labor. It is possible to promptly and accurately make a diagnosis of rupture of water during pregnancy and a diagnosis of rupture of a pregnant woman before delivery.
