Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an apparatus for predicting and detecting ovulation in mammals, which is used in the field of animal husbandry and the like to increase the probability of pregnancy, particularly in artificial insemination.

Conventional Structure and Four Points Conventional methods for predicting and detecting ovulation include, in addition to continuous measurement of basal body temperature, for example, detection of changes in the chemical characteristics of secretions that occur before ovulation. Proposed methods include focusing on the component and analyzing it using gas chromatography, or obtaining instructions through a chemical reaction using a reagent.

However, the analysis method using gas chromatography requires an apparatus a that requires complicated procedures, and as a result, only an expert can operate it. Furthermore, the equipment itself is expensive.

Furthermore, the method of obtaining instructions through chemical reactions has the disadvantage that it is difficult to handle, and the instructions are difficult to judge because they are determined by color changes and the like.

Therefore, in order to solve the above problems, the present inventors
We have developed an ovulation prediction and detection device as shown in FIGS. 1 and 2. That is, in FIG. 1, 1 is an AC generator consisting of an astable multivibrator, 1 a positive/negative pulse amplifier, etc., 2 is inserted into a detected part of a mammal,
and an electric current (-13) for applying alternating current to the detected part
Reference numeral 4 indicates a level determination device composed of a Nubu voltage comparator, and 4 a display device.This display device 4 is configured to connect a light emitting diode or the like to the level determination device 3, and display information according to each level. are doing.

6 is a power supply battery, 6 is a booster for boosting the voltage to the required voltage by an inverter circuit, etc., 7 is a voltage ratio control device connected to the power supply battery 5, and is used to check the voltage drop of the power supply battery 6. It is something.

Fig. 2 shows the structure of the main body of the leather case a, where 8 is a rod-shaped detection section made of a flexible material such as polyethylene or hard polyethylene, and the tip 9 of this rod-shaped detection a is a rod-shaped detection section. 8 by screwing. Further, an electrode 2 for applying alternating current to the detected portion is fixedly attached to the tip portion 9.

10 is a lead wire that connects the electric @2 and the electric circuit. Note that the electrode 2 is located at a distance of 0 from the end surface of the tip 9 of the rod-shaped detection section 8.
．． It protrudes 5 to 4 meters.

In general, it is known that the acid content in the vaginal secretions of many female mammals increases before ovulation. For example, before ovulation, large amounts of acids such as lactic acid and acetic acid are secreted. %The electrical resistance of vaginal secretions changes, so the water device TF: When using the device, first insert the rod-shaped detection part 8 into the vagina of the mammal you want to examine, and then turn on the switch (not shown). Then, the positive and negative pulses generated by the alternating current generating means 1 are applied to the electrode 2 fixed to the tip 9 of the rod-shaped detection part 8, and when the electrode 2 comes into contact with the detected part, etc. Stains occur due to restricted flow resistance. Then, this potential is applied to the level determination device 3, and the light emitting diode constituting the display device 4 emits light according to the output level, and it is possible to perform predictive detection of ovulation based on this level.

However, in the device configured as described above, since the electrode 2 protrudes from the end surface of the tip 9 of the rod-shaped detection part 8, the electrode 2 may or may not come into contact with the vaginal wall due to the shape of the mammal's vagina. However, there were problems in that the measured values varied widely and the ij determination accuracy was poor.

OBJECTS OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide an ovulation prediction and detection device with high measurement accuracy.

Structure of the Invention In order to achieve the above object, the present invention includes an alternating current generator;
A plurality of electrodes that apply alternating current to the detected part.

It has a level judgment device connected to this level judgment device and a display device operated by this level judgment device, and each of the plurality of electrodes is covered with a cover, and this cover is arranged so that the opposing electrode portions are exposed. According to this configuration, even if there are irregularities in the vagina, which is the detection area of the mammal, the cover will come into contact with this vaginal wall, and the electrode will not directly touch the vaginal wall. Since there is no contact between the electrodes and vaginal secretions come into contact with the electrodes, measurement accuracy can be improved regardless of the shape of the vagina.

DESCRIPTION OF ACTUAL WINDING EXAMPLE An actual winding example of the present invention will be described below based on M3 diagrams a and b. In FIGS. 3a and 3b, parts that are the same as those in the device shown in FIG. 2 are numbered the same, and only the differences will be explained. In the first example, an electric current 2 for applying an alternating current to the detected portion is fixed to the end portion of the tip portion 11 so as to protrude from the end face of the tip portion 11 . Reference numeral 12 denotes a cover that covers the plurality of electrodes 2, and this cover 12 is in contact with the electrodes 2 and is partially opened so that the opposing electrodes 2 are exposed. The space formed between two opposing electrodes is: 31!
It is set below Il+.

According to the above configuration, even if there are irregularities in the vagina, which is the detected part of the mammal, the cover 12 will come into contact with the M wall, and the electrode 2 will not come into direct contact with the vaginal wall. Since vaginal secretions that have entered the space formed between the opposing electrodes 2 come into contact with the electrodes 2, measurement accuracy can be improved regardless of the shape of the vagina.

Effects of the Invention As described above, according to the present invention, the +Ad potential for applying alternating current to the detected portion is absorbed by each cover.

In addition, this cover is opened to expose the opposing electrode portions, so even if there are irregularities in the vagina, which is the detection area of the mammal, the cover will come into contact with the vaginal wall. Therefore, secretions come into contact with the electrode without the electrode directly contacting the vaginal wall, so that the measured JffI degree can be improved regardless of the shape of the vagina.
