Description

  The subject of the present invention is a device for family planning and contraception.

  Various contraceptive methods have been developed and used so far. The most widely used methods are mechanical methods such as condoms or IUD, hormonal methods (pills) and methods with chemical properties such as suppositories, creams and foams. A device for contraception and family planning has recently been developed that can assess fertility on a particular day. Female fertilization varies over the female cycle and matures to an extent that an egg is excreted and fertilized by the ovaries about every 28 days. Egg shedding is an event known as ovulation. Eggs fertilize after only about 12 hours to at most 24 hours after ovulation. However, sperm cells live on average in a woman's body for about 72 hours or, in exceptional cases, up to 5 days. Therefore, the maximum fertilization time starts about 72 hours before ovulation and ends after about 12 hours. Therefore, all known methods for determining the fertilization stage attempt to predict the time of ovulation because the possibility of fertilization is most likely around the time of ovulation. Within the cycle, many parameters such as female body temperature or basal body temperature, LH hormone concentration and uterine mucus characteristics and quantity vary as a function of the stages of the cycle. It is theoretically possible to develop a method that allows the determination of ovulation time and female fertilization date based on these parameters.

  It is known that the female cycle is affected by complex hormonal regulation. The average duration of the cycle is 28 days, but varies between 24 and 32 days and may be irregular. A known method for determining the fertilization time of a woman is the so-called calendar method, which assumes that ovulation occurs regularly in the middle of the cycle. In this case, it is assumed that the cycle duration is 28 days and that ovulation occurs on the 14th day after the first day of the last cycle. However, since each cycle is subject to certain fluctuations, the calendar method is inadequate and is therefore not suitable for reliable contraception or family planning. WO 01/36212 describes an apparatus for determining the time of ovulation and the time of fertilization of women based solely on the calendar method.

  Furthermore, measurement of basal body temperature is a widely used method for determining ovulation. A sex hormone, gestagen is formed after each ovulation. This has the property of acting on the thermoregulatory center and increases body temperature by about 0.4-0.6 ° C. As a result, the average body temperature in the first half of the cycle (before ovulation) is lower than the average body temperature in the second half of the cycle (after ovulation). Since gestagens are formed only when ovulation has already occurred, an increase in body temperature can be considered as a reliable sign of ovulation. However, when elements such as chills or migraines are present, these elements can cause an increase in body temperature, making it difficult or impossible to determine the time of ovulation. This indicates that the use of the basal body temperature method has a low degree of accuracy and ovulation cannot be predicted.

  EP 0195207 has a temperature measuring device for measuring body temperature, the temperature measuring device is housed in a housing that can be inserted into the body, this housing has a data memory, and the data memory is adjusted by a timer. A device for regulating contraception is described, wherein a device for transmitting and receiving is provided for accumulating temperatures at defined intervals and for sending data to a data memory in response to an external command signal.

  WO 87/02876 discloses a device for measuring body core temperature, an analysis device and a display and work unit, and optionally a clock and alarm function capable of storing and analyzing daily measured body core temperature values in correlation with measurement data Describes a device for determining a basal body temperature curve and determining the date of fertilization, and for determining the time of contraception, the analysis unit may first pre-select the number of consecutively measured temperature values, Compared to the starting temperature value determined by the unit from the column of temperature values measured at the start of the cycle, more than half of the measured value d of the temperature value at the start of the cycle is at least 0. 0 less than the starting temperature value. Use a second temperature value that is 0.1 ° C higher than the starting value if it is 1 ° C lower and more than half of the most recently measured temperature values in this row are greater than the starting value. Due to the temperature value sequence moved from the start of the cycle to the end of the cycle and / or to the current measurement data, more than half of the measured temperature values are equal to or greater than the second temperature value for the first time. A new column in which the analysis unit checks and measures the measured data of the first temperature value in this column at least at the level of the second temperature value, the minimum value representing the day of ovulation is calculated If there are many minimum values, the closest day to the end of the cycle is considered the day of ovulation.

  Another method for determining ovulation is the uterine mucus method developed by Professor Billing. At the beginning of the cycle, after menstruation, a small amount of uterine mucus is drained. Around the time of ovulation, the uterine gland produces mucus, which is initially thick, gradually becoming transparent, and becoming liquid after a few days. It is assumed that the fertilization day starts with the appearance of mucus and continues for several days. Subsequently, the mucus becomes viscous again and the fertilization interval ends. However, the original characteristics of uterine mucus can be altered by the use of chemical contraceptives or other situations. In addition to uterine mucus, saliva changes during these cycles and this change can be used as a basis for determining whether ovulation has occurred.

  WO 1/06932 describes a device that can test saliva or uterine mucus to determine fertilization time.

  Ovulation can be detected by determining the concentration of luteinizing hormone (LH) in the urine, and many devices are commercially available using this method. LH increases around the time of ovulation, and LH is a good indicator of the time of ovulation. The apparatus for determining LH concentration includes a test strip having a monoclonal antibody that is specific for LH. Subsequent ELISA or EMIT methods allow determination of LH concentration based on color changes. With daily use of this method, it is possible to determine whether the LH concentration increases from one day to the next. EP 0 383 619 describes a kit having a test strip for determining the urinary concentration of LH. Although this method is more reliable than the method described at the outset, it is complicated to use and the test strips are expensive.

All the above methods can be used to determine whether ovulation has occurred. However, none of these methods alone can accurately predict the time of ovulation. Thus, commercially available devices have one or more devices that allow the implementation of multiple methods of predicting when the next ovulation will be. The reliability of contraceptive methods is indicated by the pearl index, and many commercially available devices produce values with a pearl index of 0.5-7 (the lower the value, the more reliable the device). The accuracy of the available equipment depends on the measurement method used. The problem is that the method is fairly complex to use if it has a low degree of reliability or a high degree of accuracy is required.
WO01 / 36212 European Patent No. 0195207 WO87 / 02876 WO1 / 06932 European Patent No. 0383619

  The object of the present invention is to provide a device that combines simple handling and great accuracy in predicting and determining ovulation and does not require expensive parts such as test strips with monoclonal antibodies to perform It is to be. The object of the present invention is to provide such a device.

  The device of the present invention combines the following methods to determine the estimated time of ovulation: calendar method, basal body temperature method and saliva method.

  The problem is solved by the method of claim 1.

The arrangement of claim 1 is a device for family planning and / or contraception, the device comprising:
A device for measuring basal body temperature (1), a device for inputting the first day of the cycle (7), a device for inputting saliva characteristics (8), and a data usable by the devices (1, 7, 8). A device (13), a storage device (14) that accumulates at least a portion of the available data, and a display device (4), each of which has a conclusion on the fertility of a woman on a given day It is determined as a function of at least a portion of the data that can be used by the device, and this conclusion is designed to be displayed by a display device (see FIG. 1).

  For example, in the first stage of the use of the device according to the invention, the basal body temperature of the first cycle or the first and second cycle can be achieved in order to achieve the greatest possible certainty regarding the conclusion regarding female fertilization on a given day. Only data can be considered. In an advantageous embodiment, the display device has a fixed value at the start of use of the device, for example four possible non-fertilization days, and subsequently a possible fertility or non-fertilization date on which a conclusion cannot be made on a woman. The number of days is displayed (see FIG. 2).

  In another advantageous embodiment, fixed values are used up to and including the fifth period of time prior to ovulation. As a conclusion regarding female fertilization on a given day from the sixth period, the regularity of the start of the period (input of the first day of the female period) is considered. For example, this can be done by calculating at least 6 days back from the expected date of ovulation, depending on the regularity of the beginning of the cycle.

  In another advantageous embodiment, a fixed value of the time after ovulation occurs in addition to a fixed value of the time before ovulation. This may be, for example, 2 days (ovulation + 1 day). This is obtained, for example, as a conclusion regarding female fertilization, resulting in fertilization days that can occur on at least 8 consecutive days.

  Data on saliva characteristics can be considered from the second period. However, the input of data on saliva characteristics can be used only for the user's habits without affecting the analysis of the corresponding month. In other configurations, saliva measurements can affect the conclusion regarding female fertilization any day from the third cycle, for example, reducing the number of possible fertilization days after ovulation.

  The device of claim 1 is characterized in that the data processing device is configured such that the data is evaluated differently when determining a conclusion regarding female fertilization, in which case the evaluation of the data is available It can vary as a function of previously stored data.

  According to one special configuration, the device of the present invention is a data that can be used by the device (1) for determining the basal body temperature from the data that can be used by the device (7) for entering the first day of the female cycle. The data that can be used by the device (7) that inputs the first day of the female cycle has a greater influence on the conclusion regarding fertilization of women than the data that can be used by the device (8) that inputs saliva characteristics. It is characterized by that.

  According to another special configuration, the device according to the invention makes the evaluation of the data usable by the device (1) for measuring basal body temperature advantageously 50-90%, particularly preferably 60-80% The evaluation of the data that can be used by the device (7) for inputting the day is preferably 5 to 35%, particularly preferably 10 to 30%, and the evaluation of the data that can be used by the device (8) for inputting the characteristics of saliva It is preferably 2 to 20%, particularly preferably 5 to 15%.

  The calendar method is rated lower than the temperature method due to this special configuration, because the calendar method is less reliable than the temperature method due to the natural variation of the period. Even if the calendar method is not very reliable, the calendar method is an objective method and the saliva test method is very subjective, so the weight of the saliva test method is lower than that of the calendar method.

  By a combination of the three methods, the device of the present invention can recognize temperature fluctuations caused by other factors such as chills or migraines instead of depending on the cycle, and the possible fertilization date and / or This data due to temperature fluctuations can be discarded when determining the non-fertilization date.

  One special feature of the device of the present invention is that not every measurement needs to be performed daily. In one particular configuration, the device of the present invention is characterized by having a device for measuring time and an interactive device for instructing the user to input data after a predetermined time has elapsed. In other configurations, the device of the present invention requires the input of saliva volume and characteristics, preferably 5-10 times per cycle, in particular 6-8 times per cycle by the interactive device.

  In other configurations, the device can automatically recognize the period and in particular the duration and / or progress of the period. Thus, maximum accuracy is preferably achieved before the sixth or seventh period, particularly preferably before the fifth period.

  The advantages of the device of the invention have simple handling, clear error-free display and indication and the fact that it is controlled by a new microprocessor.

  The present invention further includes applications and methods using the apparatus of the present invention.

  This device is used to determine the ovulation stage by comparing these values using the calendar method, basal body temperature method and saliva method. This device is used to prevent family planning, ie contraception or to meet the demands of children. This device is preferably used several times a week, in particular once a day.

  This device is used to process data so that conclusions regarding female fertilization can be distinguished between possible and non-fertilized dates, and the possible and non-fertilized dates are displayed in different ways visually. A display device is provided which advantageously indicates possible fertilization dates in red and possible non-fertilization dates in green.

  This device is characterized by a so-called transition date as a conclusion regarding female fertilization. This is the day when there is no distinction between a possible fertilization date and a possible non-fertilization date, and the transition date is displayed visually different from the possible fertilization date and the non-fertilization date. In an advantageous configuration, the display device displays the transition date in yellow.

  In another configuration, the device is characterized by a device that recognizes an increase in temperature from data that can be used by the device (1) for measuring basal body temperature, and the cycle at the beginning of the cycle in determining a conclusion regarding female fertilization And the second stage of the period after the temperature rise is detected.

  The terms first period of the cycle and second stage of the cycle are understood in the sense that the first phase of the cycle is the first time of time from the start of the cycle. The first phase of this cycle includes a possible non-fertilization date and a transition date to a possible fertilization date. The second phase of the cycle includes a transition date from a possible fertilization day to a non-fertilization day that can occur after the temperature rise has occurred (see FIG. 3).

  In another configuration of the device, the number of fertilization days that can occur as a conclusion regarding female fertilization at the second stage of the cycle until the end of the second period recorded by the device, for example, is preselected. The number of fertilization days that can occur after the first period is determined as a function of the analysis of the data accumulated as a conclusion regarding female fertilization in the second phase of the cycle.

  In one advantageous configuration, the device is derived from accumulated data with an indication of the duration of the cycle and / or the regularity of the course of the cycle, the number of possible non-fertilization days being determined as a function of this indication and / or Alternatively, the number of periods recorded by the device is determined as a conclusion regarding fertilization of women in the second stage of the period.

  The display according to the present invention is, for example, the standard deviation (sigma, Φ) of the day with respect to the day of ovulation (temperature rise e). The day when ovulation of the next cycle occurs correlates with the average of the days when ovulation of the preceding cycle occurred (FIG. 4). “Good” indicates an average sigma of 0.8, “Bad” indicates a sigma greater than 2.0, and “Standard” indicates a sigma of 0.8-2.0. The sigma is preferably calculated after the fourth period. There is no limit to the number of days on which ovulation occurs. It is advantageous to accumulate the last 6 to 24 cycles, preferably the last 15 cycles.

  In other configurations, the number of possible fertilization days is determined and / or influenced as a function of data that can be used by the device (8) to enter saliva characteristics as a conclusion regarding fertilization of the second stage of the cycle.

  In another configuration, the device of the invention is pre-selected as a conclusion regarding the fertilization of women in the first stage of the cycle, until the end of the fifth period recorded by the device, eg, the end of the fifth cycle recorded by the device. Preferably, the number of non-fertilization days that can occur after the second period is determined as a function of the analysis of the data accumulated as a conclusion regarding female fertilization in the first stage of the cycle.

  In one particularly advantageous configuration, the device of the present invention is derived from the accumulated data of the characteristic elements and, after the second period, the conclusion regarding the fertilization of women in the first stage of the cycle is the number of possible non-fertilization days. Is determined as a function of the characteristic element and / or the number of times recorded by the device is determined as a function of any data from the device (7) entering the first day of the period.

  The characteristic element is calculated by the computer program of the present invention (ixP2) and is an indication of homeostasis of the time of ovulation for all measured cycles ranging from 0-7. For example, if ovulation always occurs on the 14th, it is a very high characteristic element, ie, the characteristic element is 7.

  0 ≦ ixP2Φ <0.5 results in the characteristic element 7, and 0.5 ≦ ixP2Φ <1.0 results in the characteristic element 6. The low characteristic factor is an indication of a large variation in the time of ovulation. 3.0 ≦ ixP2 <3.5 yields characteristic element 1 and 3.5 ≦ ixP2Φ yields characteristic element 0.

  This method uses calendering, basal temperature and saliva methods to determine female ovulation stages and / or for family planning, and then measures female body parameters and then compares these values To do. The measured parameters preferably include body temperature and saliva and / or uterine mucus consistency, body temperature is advantageously measured by mouth, and saliva consistency is advantageously measured outside the body. This data is subsequently accumulated, preferably using a microprocessor.

  The present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram of the apparatus of the present invention.

  FIG. 2 shows the transition part No. 1 during use over several cycles. Transition part No. 1 is the first part of the cycle at the start of the cycle (exactly bleeding occurred).

  The user will not fertilize for 3 days and the display will display “probably not fertilized” for 4 days, including day 0 (before the first temperature measurement). From day 4 on, for example when using this device for contraception, a function where there should be a transition to “probably fertilized” to produce the most reliable and reliable conclusion regarding female fertilization There is a transition from a “probably not fertilized” display to a “probably fertilized” display over a period of several days. This data is processed for a very large possible certainty. It is assumed that the sperm has a survival time of 5 days and the egg cell is fertilizable up to 2 days after ovulation. The period start data of the previous period is used to determine when there should be a statistical change to “probably fertilized”.

  FIG. 3 shows, for example, the progress of the cycle stage in the display device of the device according to the invention.

  Transition part No. 1 is the first part of the cycle at the start of the cycle. For example, three possible non-fertilization dates are displayed. There will continue to be a change from a non-fertilization day that can occur, for example, over a period of 10 days to a fertilization day that can occur. Transition part No. 2 is the part of the cycle during which there is a change from a possible fertilization day after ovulation to a possible non-fertilization day. For example, the possible non-fertilization date period displayed may be 12 days.

  FIG. 4 shows one example in which an indication of the regularity of the duration of the period is derived to determine the transition part No. 2.

  FIG. 5 is a diagram of one advantageous configuration of the process-controlled minicomputer of the present invention for determining ovulation and / or for family planning. Advantageously, the three tested methods of Natural Family Planning (NFP), a calendar method, a basal body temperature method and a saliva method, are combined appropriately and analyzed using algorithm software. The result can be displayed on the display (4) and recalled at any time by starting the function key (5). The first day of the last menstrual bleeding is entered using the key (7) for cycle entry, and this device has a first calculation basis by a calendar method to give the user a group of cycles . This input can be confirmed 3-5 days after the start of the menstrual cycle. At the latest after the fifth period, preferably after the third period, the device reaches maximum efficiency, the device becomes more accurate with longer use and reaches the pearl index 0.5-2.
