Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for predicting and detecting ovulation in mammalian animals, which is used in the field of livestock farming to increase the probability of pregnancy, especially when performing human insemination. It is something.

Structure of the conventional example and its problems The conventional method of predicting and detecting ovulation is that the 7th crystal of the basal body is the first to be born; Methods have been proposed, such as focusing on changes in the chemical properties of secretions and analyzing their components using gas chromatography, and methods for obtaining indications of chemical reactions using reagents.

However, the analysis method using gas chromatography requires a device that requires visual procedures and can only be operated by experts. be.

Similarly, methods for obtaining instructions through chemical reactions must be handled carefully! F71C L <The instruction has the disadvantage that it is difficult to judge the instruction based on the judgment of color change, etc.

Purpose of the Invention The present invention (d) belongs to a method that focuses on chemical changes in secretions that occur before ovulation in mammalian animals, which solves the conventional problems as described above, reduces the size, and improves operability. ,
The object of the present invention is to provide an ovulation prediction and detection device that aims to reduce the number of ovulations.

Structure of the Invention The ovulation prediction and detection device of the present invention has an electrical structure including:
An alternating current generating means, a plurality of electrodes that apply alternating current to the detected part, and a level determination device 1'≦ connected to this voltage (4'yi).
1'' and a display device operated by this level determination device.

The electrode is arranged at the tip of a rod-shaped detection section, and the level determination device i'N and circuit sections such as a display device are housed in a main body to which the rod-shaped detection section is fixed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the downstream drawings.

In FIGS. 1 and 2, 1 is an alternating current generating means consisting of an astable multi-by-break-1 positive/negative pulse amplifier, etc.;
2 applies an alternating current to the detected part.

4 is a level determination device h1 composed of a plurality of voltage comparators.
Reference numeral 6 denotes a display device, which is configured such that a light emitting diode or the like is connected to the level determining device 4 to display a display according to the level of the item 1. 6d,'l [1, source battery, 7 is booster foil L' for boosting the voltage to the necessary voltage size by impark circuit etc., 8 is voltage ratio 1-bit device Mt connected to Ylf source tun oil 6 This is for checking the voltage drop of the power supply battery 6. Reference numerals 9 and 10 indicate operation switches, and when checking the voltage, switch 9 is turned on, and when determining the level, switch 10 is turned on.

3 and 4 show the structure of the main body of this embodiment, which is an 11tri rod-shaped detection section. Tip γ of rod-shaped detection part 11? ] 112, <11 in FIG. 4, is attached to the rod-shaped detection part 11 by screwing. At the tip 12,
A tortoise 4'M2 for applying an alternating current to the detected part is fixedly attached. Reference numeral 13 indicates a countersunk portion, and the incompletely threaded portion is removed, and the rod-shaped detection portion 11 and the tip portion 12 are brought into close contact with each other. 14 is a lead wire that connects the 'K 41g 12 part and the electric circuit. 151'l: 'i4(
The main body houses the air circuit and is equipped with operation switches 9 and 10 and a display device 5.
The timing of ovulation is determined by 1°'1゛.

Generally, the town of many mammalian animals is Jul: Before the eggs,
It is known that the acidic content present in the vaginal secretions increases, for example, before eggs are laid, a large amount of acids such as lactic acid and acetic acid are secreted, and the electrical resistance of the vaginal secretions changes accordingly. This 1'' (resistance) corresponds to an equiaxed resistance of 3.

3. When the rod-shaped detection section 11 is inserted into the vagina of the mammal to be closely examined and the switch 10 is turned on, the alternating current generating means 1 generates a negative pulse or the rod-shaped detection section When it is fixed at the tip of 11 (1v2 is applied, and when 2 is in contact with the detected part),
``, riichi', (z'f) is generated in the equal image flow resistance 3 of the detected part. 1?blasphemy/
The light emitting diodes 1' and 5 emit light, and depending on this level, predictive detection of υ1]1 can be performed.

In the example device, the rod-shaped detection part 11 and the main body 15 are integrated (~, the electric circuit part is housed in the main body 15, and the size can be reduced by 4"). It is handy and easy to operate.When checking the IL pressure of the ton source 6, it is possible to turn on the switch 9 and make a single nick.

Since ili: 4iυi2 is provided on the end face of the tip of the rod-shaped detection part 11, it can be pressed against the detected part of the vagina 11'' (part) with a constant J→-1 force, thereby stabilizing the detection part. 7 detection measurements can be made.

Incidentally, in the above embodiment, the level grouping fi<f4 and the number of display elements are set to 6, but the number is limited to 1. r, (,i may be increased or decreased as needed).

Effects of the Invention From the above example of cans, it is very clear.
Predictive detection of 1 egg; Placement (+: 1, small, easy to operate, low f1111 rating, ■yuzo) is something that can be provided.

It is stable by installing the 7IL God i part at the tip.
This level determination result can also be input.
