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 animal husbandry and the like to increase the probability of pregnancy, particularly when performing artificial insemination.

Structure of conventional examples and their problems Conventional methods for predicting and detecting ovulation focus on, for example, changes in the chemical characteristics of secretions that occur before ovulation, in addition to continuous measurement of basal body temperature. Proposed methods include analyzing the components using gas chromatography, and obtaining instructions through chemical reactions.

However, the analysis method using gas chromatography requires an apparatus that requires complicated procedures, and as a result, there is an electrical point that only experts can operate. Also, the device itself is a first-year high school student.

In addition, the method of obtaining instructions through chemical reactions is difficult to handle, and the instructions are determined based on color changes, etc., which has the drawback of being difficult to judge.

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 alternating current generator consisting of an astable multivibrator, a positive/negative pulse amplifier, etc., and 2 is the number of nuclei inserted into the detected part of the complement animal and for applying alternating current to the detected part. , 3 is a level judgment device composed of a plurality of voltage comparators, 4 is a display device, and this display device 4 connects a light emitting diode or the like to the level judgment device 3 to display information according to each level. It is configured as follows.

Reference numeral 5 denotes a power supply battery, 6 a booster for boosting the voltage to the required voltage using an inverter circuit, etc., and 7 a voltage comparison device connected to the power supply battery 6, which is used to check the voltage drop of the power supply battery 6. .

FIG. 2 shows the configuration of the main body of this device. Reference numeral 8 denotes a rod-shaped detection section made of a flexible material such as polyethylene or hard polyethylene. It is attached by screwing it on. 'Furthermore, an electrode 2 for applying an alternating current to the detected part is fixed to the tip part 9.' 10 is a lead wire that connects the electrode 2 and the electric circuit.

The electrode 2 protrudes from the end surface of the tip 9 of the rod-shaped detection section 8 by 0.5 to 41 rrrn.

In general, it is known that the acidic content in the vaginal secretions of many female complement animals increases before ovulation; for example, before ovulation, acids such as lactic acid and acetic acid is secreted in large quantities,
The electrical resistance of vaginal secretions changes, so when using this device, first insert the rod-shaped detection section 8 into the vagina of the mammal you want to examine, and then turn on the switch (not shown). Positive and negative pulses generated by the alternating current generating means 1 are applied to the electrode 2 that is properly attached to the tip 9 of the rod-shaped detection section 8, and when the electrode 2 comes into contact with the detected section, the potential is increased due to the equivalent DC resistance of the detected section. occurs. And this potential is level judgment device m
3, and this output causes the light emitting diodes constituting the display device 4 to emit light according to the 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 rod-shaped detection part 8 and the tip part 9 to which the electrode 2 is fixed have the same diameter, when the rod-shaped detection part 8 is pushed into the vagina of a sentinel mammal, the detected part There is a problem in that the mucus near the vaginal opening must be pushed in before the electrode 2 reaches it, and as a result, accurate measurements cannot be made.

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;
It has a plurality of electrodes for applying alternating current to the detected part, a level judgment device connected to these electrodes, and a display device operated by this level judgment device, and the electrode is attached to the tip of the rod-shaped detection part. is arranged so as to protrude from the end face of the rod-shaped detection part, and the body diameter of the tip part of the rod-shaped detection part is made larger than the body diameter of the rod-shaped detection part, and a vertical groove is provided in this body part. For example, when a rod-shaped detection part is pushed into the vagina of a mammal, mucus near the vaginal opening can escape through the vertical groove provided in the body of the tip, so it is not pushed into the vagina. As a result, the mucus in the back of the vagina can be measured, allowing accurate 8IIJ determination.

Description of Leprosy Example A leprosy example of the present invention will be described below with reference to FIGS. 3a and 3b. In FIGS. 3a and 3b, reference numeral 11 denotes a tip portion attached to the rod-shaped detection portion 8 by screwing, and an electrode 2 for applying alternating current to the detected portion is connected to the tip portion 11.
It is fixed and protrudes from the end face of 1. Further, the body diameter of the tip end portion 11 is larger than the body diameter of the rod-shaped detection portion 8, and several M longitudinal grooves 12 are provided in this body portion.

According to the above configuration, when the rod-shaped detection part 8 is pushed into the vagina of a mammal, the mucus near the vaginal opening can escape through the vertical groove 12 provided in the body of the tip part 11. As a result, the mucus deep inside the vagina can be measured, allowing for accurate measurements.

Effects of the Invention As described above, according to the present invention, at the tip of the rod-shaped detection part,
A heavy weight is disposed so as to protrude from the end face of the tip, and the body diameter of the tip of the rod-shaped detection section is made larger than the body diameter of the rod-shaped detection section, and a vertical groove is provided in the force control section. Because there are
When the rod-shaped detection part is pushed into the vagina of a mammal, the mucus near the vaginal opening can escape through the vertical groove provided in the body of the tip, and as a result, the mucus near the vaginal opening enters the vagina. Since it is not pushed in and the mucus deep within the embryo can be determined, accurate measurements can be made.
