Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a card for calculating menstrual days.

[Conventional technology]

Conventionally, for the purpose of contraception or pregnancy, methods have been implemented to check the days that are appropriate for each. This method includes the Ogino calculation method and the method of measuring basal body temperature.

[Problem that the invention attempts to solve]

When using the above-mentioned conventional Ogino calculation method or method of measuring basal body temperature, or even the vaginal discharge method, it is complicated to implement, and there are cases where errors in calculation occur and the effect is not always fully demonstrated. . In addition, there are dial versions of the Ogino calculation method mentioned above, dial versions of the method for measuring basal body temperature, dial versions of the vaginal discharge method, and dial-type menstrual date calculation cards that combine these methods. These dial-type menstrual date calculation cards have been available for a long time (for example, see Utility Application No. 59-124506 and Utility Model Application No. 54-25108). The configuration was complicated, making it cumbersome and inconvenient to use. Therefore, there has been a need for a menstrual date calculation card that allows anyone to very easily confirm the period suitable for contraception or pregnancy.

This invention does not use the conventional Ogino calculation method to measure basal body temperature, and also does not rely on the vaginal discharge method.
It is an object of the present invention to provide a portable menstrual date calculation card that can solve the above-mentioned problems and meet the above-mentioned demands.

[Means for solving problems]

The means of the present invention to solve the above problems consists of a business card-sized mount and a circular rotating paper rotatably attached to the mount. The circular rotating paper is placed below the explanation column, and the date written with numbers from 1 to 30 along the circumference is written on the mount of the ring-shaped part adjacent to the outside of the circumference of the rotating paper. There is a column of numbers to display, and the annular part adjacent to the outside of the circumferential part of the rotary paper has period A, period A, related to menstruation, respectively.
A field is provided along the circumference to display B, C, and D, and among A, B, C, and D, A is the period during menstruation, B is the period when pregnancy is possible, and C is the period during which pregnancy is possible. indicates a period during which pregnancy is easy, and D indicates a period during which pregnancy is difficult; A, B, C, and D above correspond to the dates in the numerical column displaying the date; and during period A during menstruation. This is a menstrual date calculation card with a triangular mark to match the menstrual start date.

[Effect]

By rotating the rotary paper on the mount and checking the menstrual dates, it is very easy to check the due date for each menstruation.

〔Example〕

Next, the present invention will be described by way of examples with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the present invention;
FIG. 2 is a plan view of FIG. 1. In these figures, a circular rotating paper 2 is rotatably attached to a business card-sized mount 1 at the center by a stopper 3 as shown by an arrow R. A usage instruction field 4 is provided on the upper surface of the mount 1. The rotary paper 2 is provided below the usage instruction column 4. The mount 1 portion of the annular portion 8 adjacent to the outside of the circumferential portion 6 of the rotary paper 2 is provided with 1 or 2 along the circumferential portion 6 of the rotary paper 2.
A number consisting of 30 (in other words, representing one month) is written, and the number field 5 is used to display the date. On the other hand, an annular portion 7 is provided adjacent to the inner side of the circumferential portion 6 of the rotary paper 2, and periods A, B, C, and D related to menstruation are arranged along the circumference of the annular portion 7. They are divided and provided corresponding to the date numbered 5 in the number column. That is, A indicates the period during menstruation, B indicates the period during which pregnancy is possible, C indicates the period during which pregnancy is likely, and D indicates the period during which pregnancy is difficult. Furthermore, a triangular mark Aa is provided in the area displaying the period during A's menstruation.

When using this card, the triangle mark at A
If you match Aa to the first day of your period (here, the 1st),
Each period of B, C, and D can be confirmed very easily. Of course, there are individual differences in menstrual cycles, so users need to consider their individual characteristics when using the product. This card is made of paper the size of a business card, so it is extremely easy to carry.

[Effect of idea]

As explained above, the present invention uses the Ogino calculation method or the method of measuring basal body temperature, and
Without using the vaginal discharge method, by matching the numerical column containing the date with the period related to menstruation and aligning the triangle mark with the start date of menstruation, it is extremely easy to know the period suitable for contraception or pregnancy. be able to. In addition, the present invention is easy to carry, and since there is a space for instructions on how to use it on the top of the mount, it has the effect of making it easy to learn how to use it.
