The output sides of OR1 to EOR5 are connected to voltage dividing resistors R32 to R36 for dividing the light emission signals applied to the light emission signals of the light emitting diodes DP1 to DP5.

Incidentally, the impedance detecting means 2
The sum of the resistance values of the voltage dividing resistors R18 to R23 at 0 is
The impedance value between the electrodes 3 and 3 in the drinking water for the mammal to be measured, for example, tap water, well water or water having the same electrical resistance, is set to be slightly smaller. Since the temperature is 0.5 ° C., the electrodes 3 and 3 are immersed in water at 38.5 ° C., which is slightly smaller than the equivalent impedance value between the electrodes 3 and 3 at that time and is about 2.14 kΩ. Specifically, when the electrodes 3 and 3 are immersed in water at 38.5 ° C.,
The light emitting diode DP1 is set to light up.

The voltage dividing resistor R23 is set to be substantially equal to the equivalent impedance value of the blood of the mammal to be measured. For example, in the case of a pig, it is about 0.78 kΩ. When the electrodes 3, 3 are immersed in blood, the light emitting diode DP1 is set to be turned off.

Further, the sum of the resistance values of the partial pressure resistors R19 to R23 is equal to the equivalent impedance value in the vaginal mucosa at a time suitable for injecting the liquid sperm into the uterus of the mammal to be measured. For example, in the case of a pig, it is set to about 1.88 kΩ.

Further, the voltage dividing resistors R20 to R23
Is set to be equal to the equivalent impedance value in the vaginal mucosa at a time suitable for injecting frozen sperm into the uterus of the mammal to be measured. For example, in the case of a pig, 1 It is set to about .644 kΩ.

The sum of the resistance values of the voltage dividing resistors R21 to R23 is set so as to be substantially equal to the maximum equivalent impedance value of the mucous membrane in the vagina at the time of non-ovulation of the mammal to be measured at the time of non-ovulation. For example, in the case of a pig,
It is set to about 1.00 kΩ.

Further, the sum of the resistance values of the partial pressure resistors R22 and R23 is substantially equal to the lower half of the equivalent impedance value of the mucous membrane in the vagina at the time of non-ovulation in the non-ovulatory period of the mammal to be measured. For example, in the case of a pig, it is set to about 0.867 kΩ.

Next, the basic process of detecting the ovulation timing of an individual by the above-described apparatus for measuring the ovulation timing of a mammal will be described. First, the gripper main body 1 is gripped and the rod-shaped detector 2 is moved to the individual. Inserted into the vagina and the electrode 3,
3 is pressed against the mucous membrane in the vagina.

When the operation switch 22 of the gripper body 1 is turned on in this state, a voltage generated according to the value of the impedance equivalent circuit 21 between the electrodes 3 and 3 is generated by the diode D.
1, the operational amplifiers OP1 to OP6 are input to the non-inverting input terminals of the operational amplifiers OP1 to OP6.
The voltage divided by the resistors R17 to R23 is applied to the inverting input terminal 6 to thereby obtain the voltage value from the impedance equivalent circuit 21 and the operational amplifiers OP1 to OP6.
Each voltage value is compared, and the comparison result is input to each of the exclusive OR circuits EOR1 to EOR5.

At this time, the voltage input to the inverting input terminal of each of the operational amplifiers OP1 to OP6 is applied from the operational amplifier OP6 to OP1 in the form of a stepwise large value according to the resistances R23 to R17. At the same time, each of the exclusive OR circuits EOR1 to EOR5 is
In order to take the exclusive OR of the neighbors of P1 to OP6,
One of the light emitting diodes DP1 to DP5 is turned on according to the value of the impedance equivalent circuit 21.

The sum of the resistance values of the voltage dividing resistors R18 to R23 in the impedance detecting means 20 is set to be substantially equal to the impedance value in water, and the sum of the resistance values of the voltage dividing resistors R19 to R23 is determined in the vagina. Since the equivalent impedance value of the mucous membrane is set equal to the value in a state suitable for injecting liquid sperm, the state in which the light emitting diode DP1 is lit indicates the time for injecting frozen sperm, and similarly, When the light emitting diode DP2 is turned on, it indicates a time suitable for injecting liquid sperm.

When the impedance value between the electrodes 3 and 3 is equal to the equivalent impedance value in water, signals are input from both the operational amplifiers OP1 and OP2 to the exclusive OR circuit EOR1, so that the light emitting diode DP1 is turned off. By immersing the electrodes 3 and 3 in water using such an operation, it is possible to check (diagnose) the device itself.

Further, the sum of the resistance values of the voltage dividing resistors R21 to R23 in the impedance detecting means 20 is set to be equal to the maximum impedance value of the impedance equivalent circuit 21 in the mucous membrane in the vagina of the individual at the time of impotence in a non-ovulatory state. Therefore, when the light emitting diode DP4 or DP5 is turned on, it indicates a time when the child cannot be pregnant.

The light-emitting diode DP4 represents a high-level impedance value during the period of non-fertility, and the light-emitting diode DP5 represents a low-level impedance value during the period of non-fertility. In the case of the gestation period, it is possible to determine whether “the ovulation time is short” or “the ovulation has been completed”. In this case, the light emitting diode DP3 is in the middle of the fertile or non-fertile period. , The so-called “gray zone” is shown.

On the other hand, since the resistance value of the voltage dividing resistor R23 in the impedance detecting means 20 is set to be slightly larger than the impedance value of the blood of the mammal to be measured, the electrodes 3, 3 are connected to the blood of the individual. When immersed in the light emitting diode DP5, the light emitting diode DP5 is turned off.

That is, as described above, by immersing the electrodes 3 and 3 in water or a liquid equivalent to the blood of an individual, it is possible to perform a zero level check of the ovulation timing measuring device.

FIG. 4 shows the measured data of the individual animal consisting of mammals, for example, a sow, in which the equivalent impedance value of the vaginal mucosa from the non-ovulation period to the ovulation period changes over time. The equivalent impedance value of the vaginal mucosa at the time of non-ovulation,
It begins to increase from 42 to 32 hours before the ovulation period, approaches the equivalent impedance value of water without limit, becomes almost equal to the equivalent impedance value of water immediately before the ovulation period, and decreases rapidly thereafter, It has a pattern that has a minimum value over time.

In order to perform artificial insemination of pigs, when ordinary liquid sperm is injected, the injection is performed about 7 to 5 hours before ovulation.
By setting the time when 2 lights up as about 7 to 5 hours before ovulation, and when injecting frozen sperm, the time when the light emitting diode DP1 lights up is set as 2 hours before ovulation, The timing of semen injection is determined, and therefore, when any of the light emitting diodes DP3 to DP5 is lit, it can be determined that "no pregnancy".

However, the time course of the equivalent impedance value from the non-ovulation period to the ovulation period of the mucosa in the vagina of a target mammal, for example, a pig, depends on the nutritional intake, the manner of growth, and the genetics. Since the relationship between the equivalent impedance value of the vaginal mucosa and the time is not always constant due to differences, etc., applying measurement data of only one pig to all other pigs requires ovulation timing, That is,
The timing of semen injection may be missed and artificial insemination cannot be performed accurately and reliably.

Therefore, in the ovulation timing apparatus according to the present invention, as shown in FIG.
The storage control means 51 connected to the impedance detection means 20 by classifying the measurement data associated with the temporal change of the equivalent impedance value in the period from the non-ovulation time to the ovulation time in the vaginal mucosa of the individual detected by 0 The measurement data stored in the measurement data storage means 52 is further output from the data output means 53 in consideration of the elapsed time for each individual.

In this case, as the measurement data of the individual stored in the measurement data storage means 52, for example, data on 100 individuals can be collected. It may be displayed directly on the digital display unit 50 of the device, or may be connected and displayed on a personal computer or the like. The display form on the display unit 50 may be, for example, image display, scroll display, numerical display or graph display. There is.

An automatic storage means 54 is connected between the impedance detection means 20 and the measurement data storage means 52 via the storage control means 51. The automatic storage means 54 controls the impedance detection means. 2
In addition to determining the rate of change of the impedance value in the vaginal mucosa of the individual detected by 0, the impedance value when the value falls below a predetermined set value is stored in the measurement data storage means 52 as measurement data. ,And,
The end of the measurement is displayed by lighting a light emitting diode or the like. Note that this measurement end display may be displayed by electronic sound such as a beep, vibration, or the like.

In this case, the automatic storage means 54 is activated by pressing the measurement start button 19 provided on the grip portion main body 1, and operates as described above.

Further, a reference data storage means 55 is connected to the storage control means 51. The reference data storage means 55 has a periodic data stored in the measurement data storage means 52 which is detected by the impedance detection means 20 and stored in the measurement data storage means 52. The change of the impedance value in the vaginal mucosa of a plurality of individuals during the period from the non-fertility period to the fertile ovulation period is stored as a reference data sequence, and the plurality of changes stored in the reference data storage unit 55 are stored. A reference data column,
The ovulation timing prediction output unit 56 compares the impedance value in the vaginal mucosa of any individual newly detected by the impedance detection unit 20 and stored in the measurement data storage unit 52 by the ovulation timing prediction output unit 56, so that the ovulation timing of any individual Is predicted and output to the digital display unit 50.

Therefore, in the ovulation timing measuring apparatus according to the present invention, the impedance value in the vaginal mucous membrane of any individual detected by the impedance detecting means 20 and stored in the measurement data storing means 52 is stored in the reference data storing means. By comparing with the reference data sequence stored in 55, the ovulation timing can be predicted and determined for each individual.

That is, during the first artificial insemination, the impedance is measured by the impedance detection means 20 and stored in the measurement data storage means 52 during the period from the period of repetition of the individual that is not able to become pregnant to the time of ovulation when it can be fertile. By recording the change of the impedance value in the detailed vaginal mucosa in the reference data storage means 52 as a reference data sequence, at the time of the second or subsequent artificial insemination of the individual, once or at an appropriate time before ovulation Several measurements are performed by the impedance detecting means 20 and stored only in the measured data storage means 52, and thereafter, the impedance values stored in the measured data storage means 52 and the reference data storage means 55 are stored. By comparing the reference data sequence with the ovulation time prediction output means 56, Eggs time it is possible to easily and accurately predict and determine.

The display mode of the digital display section 50 is switched and displayed by mode switching means (not shown).

The reference data storage means 55 stores a plurality of, for example, three to five, changes in the impedance value in the mucous membrane in the vagina of the individual during the period from the period of repetition that cannot be fertilized to the period of ovulation that can be fertile. In the case of mammals that can be classified into types, data on individuals showing changes representing each type is stored as a reference data string, and the impedance detection means 20 newly detects and stores the measurement data storage means 52 By comparing the impedance value in the vaginal mucosa of any individual stored in the above with the plurality of reference data strings stored in the reference data storage means 55 by the ovulation timing prediction output means 56, The ovulation timing of a similar individual may be predicted and output to the digital display unit 50.

In other words, the ovulation timing measuring device according to the present invention having the above-described configuration uses the ovulation timing prediction output means 56 to
The impedance value in the mucous membrane in the vagina of any individual detected by the impedance detection means 20 and stored in the measurement data storage means 52 is stored in the reference data storage means 55
The ovulation timing is predicted and determined for each individual by comparing with a reference data sequence of a similar type stored in the storage device.

Therefore, in the ovulation timing measuring apparatus according to the present invention, the ovulation timing is measured at the time of the first artificial insemination,
The type of change in impedance value is determined and recorded based on detailed measurement data stored in the measurement data storage means 52 during the period from the period of repetition of the individual that cannot be fertilized to the period of ovulation at which it can be fertile. By doing so, at the time of the second or subsequent artificial insemination of the individual, one or several measurements are performed by the impedance detection means 20 at an appropriate time before ovulation, and the measurement is simply stored in the measurement data storage means 52. Ovulation timing prediction output means 5
6, the ovulation time of any individual can be easily and accurately predicted and determined.

Incidentally, it goes without saying that the ovulation timing measuring apparatus according to the present invention can also be used for, for example, contraception or uterine diagnosis.
