Description

Detailed Description of the Invention (Industrial Application Yf) This invention is used in obstetrics and gynecology. The present invention relates to a pregnancy calendar calculation and display device configured to calculate the pregnancy calendar days of a pregnant woman, such as the number of days and expected delivery date, and to display the calculated pregnancy calendar days.

(Prior art) As this type of device, conventionally,
As seen in the publication, by reading the examination date and LMP, the number of days of pregnancy and expected delivery date (hereinafter abbreviated as EDC) up to the present time (at the time of examination) are calculated, and the calculated current A device is known in which the pregnancy elapsed date (hereinafter abbreviated as GA) is displayed in weeks and the LMP is displayed in months and days.

(Problems to be Solved by the Invention) According to the conventional pregnancy calendar calculation and display device as described above, it is possible for a doctor or the like to calculate and display a pregnant woman's pregnancy calendar by simply operating a switch. Compared to analog calculation and display devices such as slide rule style and peach ring style that were used up until now, there are no operational complications, misreadings, or errors due to scale misalignment, making it easier to determine the predetermined pregnancy calendar date. Although it has the advantage of being able to be calculated and displayed quickly and accurately, it is very important to evaluate the fetal growth status for a pregnant woman to give birth normally. It is not possible to understand the progress of pregnancy, such as growth rate, weight gain, blood pressure, and fetal weight in relation to the current GA, and these fetal growth status evaluation factors are measured separately from the pregnancy calendar calculation. However, it is necessary to evaluate the progress by comparing it with the calculated pregnancy history, so it is not only time-consuming and troublesome to evaluate the growth status of many pregnant women at each GA, but also a time-consuming process. Moreover, there was a possibility that incorrect evaluations could occur, such as misunderstanding measurement data between pregnant women.

This invention was made in view of the above circumstances, so in addition to the original pregnancy calendar calculation display function such as GA and EDC, pregnancy is based on the normal values and normal ranges of the growth status evaluation factors measured on each pregnant woman's side. It is an object of the present invention to provide a pregnancy calendar calculation and display device that allows the progress to be easily and accurately grasped periodically.

(Means for Solving the Problems) In order to achieve the above object, the pregnancy calendar calculation and display device according to the present invention reads the medical examination date and the first day of the pregnant woman's last menstrual period, and calculates the pregnancy progress up to the medical examination date. In a pregnancy calendar calculation/display device that is equipped with a means for calculating the number of days and displaying the weekday, as well as calculating and displaying the expected day of delivery, the uterine fundus length value, abdominal circumference increase value, weight increase value, A memory that periodically measures fetal growth status evaluation factors such as blood pressure values and fetal weight values, and stores the measured data by inputting it, and a memory card that stores the above measured data for recognition by each pregnant woman. and a means for automatically creating and displaying a pregnancy progress chart for each pregnant woman based on the data stored in the memory and the memory card. Features.

(Operation) According to the present invention, at the time of medical examination, a doctor or the like inputs the medical examination date and LMP for each pregnant woman, thereby automatically calculating and displaying at least the calendar dates of pregnancy such as GA and EDC. At the same time, fetal growth status evaluation factors such as uterine fundus length, abdominal circumference increase, weight gain, blood pressure, and fetal weight are measured on each side of the pregnant woman at regular intervals. The measurement data is stored in the memory and in the memory car for recognition on each side of the pregnant woman. Then, based on the data measured and input on the first examination day and the previous data stored in the memory card and read out, the kE pregnancy progress chart for each side of the pregnant woman is calculated based on the normal values and the normal values. By displaying the information along with a guideline indicating the range, it is possible to clearly observe the progress related to each of the above factors and use it for screening for, for example, growth retardation due to intrauterine assisted light, multiple gestation, macrosomia, polyhydramnios, etc.

In other words, the main fetal growth status evaluation factors that are measured regularly, such as every few weeks, are a pregnant woman's fundal length, interlayer increase, weight gain, blood pressure, and fetal weight. Other possible causes include the pregnant woman's urine protein level, urine sugar level, and fetal heart sounds. Among these, the fundal length value is determined by directly measuring the tomographic image obtained from ultrasound scanning, and the fetal weight is also determined by directly measuring the ultrasound tomographic image. Calculated from the diameter of the head (pi).

In addition, the subject matter, weight, blood pressure, etc. are usually measured using common measuring instruments.
