Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a predictive detection device for ovulation in mammals, which is used in the field of livestock farming to increase the probability of pregnancy, especially when performing artificial insemination. .

Configuration of the conventional example and its problems Proposed methods include focusing on changes in the chemical properties of the secreted material and analyzing its components using gas chromatography, and methods that obtain instructions through chemical reactions using reagents.

However, the analysis method using gas chromatography has the disadvantage that it requires an apparatus that requires complicated procedures and cannot be operated by experts. Furthermore, the equipment itself is expensive.

Similarly, the method of obtaining an indication by a chemical reaction has the disadvantage that it is difficult to handle and the indication is difficult to judge because it is based on a color change or the like.

OBJECTS OF THE INVENTION The present invention belongs to a method that focuses on the chemical changes in secretions that occur before ovulation in mammals, and it solves the conventional problems as described above, is miniaturized, and improves operability. The present invention provides a rational ovulation prediction and detection device that can be applied to various animals.

The ovulation prediction and detection device of the present invention comprises an alternating current lifetime means and a plurality of electrode parts that apply alternating current to the detected part. B.

4. From the level judgment device connected to the pole and the display device that operates many times depending on the level judgment device. It consists of an electrical configuration, and a mechanical configuration in which a Kiyoaki detection unit provided with an electrode part and a main body housing an electric circuit part are removably fastened.

Description of the real sister example The following is a description of the real sister example of the real sister 1j based on the accompanying drawings.

In Fig. 1 and Fig. 21, 1 is an AC generating means consisting of an astable multivibrator-1 positive/negative pulse amplifier, etc., 2il-j is an electrode for applying alternating current to the detected part, 3 is the part to be detected, etc. 04-1, which is a side flow resistance, is a level judgment device made up of a plurality of voltage comparators; 5 is a display device; a light emitting diode, etc. is connected to the level judgment device 4, and a display is made according to each level; It is configured to do so.

6 is a power supply battery, 7 is a booster equipment for boosting the voltage to the required voltage for an inverter circuit, etc., 8 is a voltage comparison device connected to the power supply battery 6, and 7 is a voltage comparator connected to the power supply battery 6.
This is something that should not be checked.

9.10 is the operation switch, and if you want to use the power switch, turn on switch 9, and if you want to judge the level, turn on switch 9.
Turn on switch 10.

Figures 3 and 4 show the structure of the main body of this embodiment, and 11 is a rod-shaped detection part with a length A and a diameter B with an electrode 2 at its tip, and a fastening part 12 at the base. By the way, main body 13
The agreement has been concluded. The main body 13 houses electric circuit parts other than the electric circuit WL2, and is equipped with operation switches 9, 10 and a display device 5, and determines the egg season depending on the display position of the display device 6.

For the fastening part 12i, as shown in FIG.
There is a socket part 15 fixed by 4, and a screw is threaded on the outer periphery of the socket part 15 to be screwed into a cover 16 at the base part. Inside the socket part 15, a connector 18 is attached on an insulating plate 17, and this insulating plate 17 is attached to the boss at the center of the socket part 16 with a screw 19.) 20 is a rod-shaped detection part. Eleven electrode pins are fitted into the connector 18 to establish electrical connection.

A lead wire 21 connects the electrode pin 20 and the electrode 2.

FIG. 5 is an enlarged sectional view of the tip A1, 1 of the rod-shaped detection section 11, and the electrode section 2 is a tip member 2 screwed onto the rod-shaped detection section 11.
It is stuck on 2-h.

In general, it is known that the acid content in the vaginal secretions of many female mammals increases before ovulation. is secreted in large quantities, and therefore the electrical resistance of vaginal secretions changes. This resistance corresponds to the equivalent resistance 3.

The operation in the above configuration will be explained. First, when the rod-shaped detection section 11 is inserted into the vagina of the mammal to be examined and the switch 10 is turned on, positive and negative pulses generated by the alternating current generating means 1 are transmitted to the tip of the rod-shaped detection section 11 (KI).

When the applied voltage is applied to the attached electrode 2 and the electrode 2 comes into contact with the detected part, the stain position -AC5>/
-fZ, -;r to r) Sauce! erIrr+/bear1-.
ul+;6AgIlpA&rf:lIi+u, and a Y: diode forming the display device 5 is generated at this output according to the Urelevel, and it is possible to perform predictive detection of set eggs based on this level.

In the apparatus of this embodiment, the rod-shaped detection section 11 and the main body 13 are integrated and placed inside the main body 13. U: Since the air circuit part is housed, it can be downsized and is handy and easy to operate. Further, when checking the voltage of the power supply battery 6, it is possible to turn on the switch 9 and check whether one light emitting diode lights up or not.

Since the electrode 2 is provided on the end face of the tip of the rod-shaped detection part 11, it can be pressed against the vaginal floor, which is the part to be detected, with a constant pressure, thereby enabling stable detection and measurement.

The rod-shaped IJ sauce 91511 has a removable structure, with the base part 15 screwed to the cover 16, so the length and diameter B in Fig. 3 are We have decided to prepare multiple rod-shaped detection parts with different shapes depending on the type of mammal that we want to investigate.
It can accommodate various types of animals.

In the embodiment described in ``-'', the level of the level determination device 40 and the number of display elements are set to 6, but the number is not limited to this and may be increased or decreased from 1 to 1 as appropriate. It is something that

Effects of the Invention As is clear from the above actual case, the 4'll egg predictive detection device of the present invention is small, easy to operate, and can be manufactured and delivered at low cost.

In addition, by making the rod-shaped detection part equipped with the electrode part detachable, it is possible to use the detection 7r and IH, which are compatible with multiple (Φ class mammals), once a month and replace them as needed. You will be able to do it.
