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. .

Structure of conventional examples and their problems Conventional methods for predicting and detecting ovulation include continuous measurement of basal body temperature, as well as detection of changes in the chemical characteristics of secretions that occur before ovulation. Proposed methods include focusing on the components and analyzing them using gas chromatography, and methods of obtaining υ instructions through chemical reactions using reagents.

However, the analysis method using gas chromatography requires an apparatus that requires complicated procedures, and can only be operated by experts. Furthermore, the device itself is expensive.

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

Purpose of the Invention The present invention relates to a method for observing the chemical changes in the secretions of mammals that occur before ovulation. VC1 provides a highly safe and easy-to-use ovulation prediction and detection device.

Structure of the Invention The ovulation prediction and detection device of the present invention comprises an alternating current generating means, a plurality of electrode sections for applying alternating current to a detected section, a level determining device connected to the electrode section, and a display device operated by the level determining device. and a mechanical structure such as a main body in which a rod-shaped detection part provided with an electrode part is formed of a flexible phase material such as ijj material, and an electric circuit part is housed. Further, the rod-shaped detection section is made of a material such as polyethylene or hard polyethylene.

DESCRIPTION OF EMBODIMENTS One embodiment C of the present invention will be described below with reference to the accompanying drawings.

In Figures 1 and 2, 1d is an AC generating means consisting of an astable multivibrator-1 positive/negative pulse amplifier, 2 is an electrode for applying AC to the detected part, 3 is the etc. of the detected part, etc. It is the measured flow resistance.

4 is a level determination device composed of a plurality of voltage comparators, 6
1 is a display device, which is configured to connect a light emitting diode or the like to the level determining device 4 and display information according to each level.

6 is a power source battery, 71-J is a booster to raise the voltage to the required voltage using an inverter circuit, etc., and a voltage comparator device connected to the 8 it two power source batteries 6.
This is a useless thing to check for voltage drop.

Reference numeral 9.10 is an operation switch, and when checking the voltage, the switch 9 is turned on, and when the level is to be judged, the switch 10 is turned on.

FIGS. 3 and 4 show the structure of the main body of this embodiment. Reference numeral 11 indicates a rod-shaped detection portion made of a rigid material such as polyethylene or hard polyethylene. As shown in FIG.
It has been reprinted with screws. At the tip 12, an electrode 2 for applying alternating current to the detected part is attached with a 1 inch diameter. I'm here.

Reference numeral 13 denotes a counterbore portion with an incompletely threaded portion removed so that 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 second electrode and the electric circuit.

Reference numeral 16 denotes a main body housing electric circuit parts other than the electrodes 2, and is equipped with operation switches 9, 10 and a display device 5. The timing of ovulation is determined based on the display position of the display device 5.

In general, it is known that the acidic content present in the vaginal secretions of many female mammals increases before ovulation. It is secreted in large quantities, thus changing the electrical resistance of vaginal secretions. This resistance corresponds to the equivalent resistance 3.

The operation in the above configuration will be explained. When the rod-shaped detection part 11 is inserted into the vagina of a mammal and the switch 10 is turned on, positive and negative pulses generated by the alternating current generating means 1 tc are applied to the electrode 2 fixed to the tip of the rod-shaped detection part 11. When the voltage is applied and the electrode 2 comes into contact with the detected part, a potential is generated by the isometric flow resistance 3 of the detected part. This potential is applied to the level determining device 4, and the light emitting diode constituting the display device 6 emits light according to the output level, and ovulation can be predicted and detected based on this level.

In the device of this embodiment, the rod-shaped detection section 11 and the main body 16 are integrated, and the electric circuit portion is housed within the main body 15, so that it can be miniaturized and easily operated by a handheld device.

-1 When checking the voltage of the power supply battery 6, it can be checked by turning on the switch 9 and checking 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 bottom of the chest, which is the part to be detected, with a constant pressure, thereby allowing stable detection and measurement.

Furthermore, since the rod-shaped detection part 11 is made of a flexible material with toughness such as polyethylene or hard polyethylene, the 8 dimensions in FIG.
Even though it is long and thin, it does not cause any inconvenience such as breaking in the middle.

In addition, when the rod-shaped main detection part 11 is inserted into the womb of a mammalian subject during use, safety is ensured because the main detection part flexes even if the animal moves or breaks open. Do t.

Effects of the Invention As is clear from the above examples, the]''
- The knowledge detection device has a small size and is easy to operate, and can be manufactured and provided at low cost.

By forming a rod-shaped detection part with a YIi polar part on a flexible material such as polyethylene or hard polyethylene, it can be detected in the womb of the oil hole animal being tested during use. Place the Uj object on the platform where it is inserted. Safety is ensured even when the equipment is used.
