Description

[Detailed Description of the Invention] Field of Use in Concubine The present invention relates to a predictive detection device for ovulation in mammals, which is used in the field of mass storage, etc., particularly to increase the probability of pregnancy when performing artificial insemination. It is.

Structure of the conventional example and its problems Conventional methods for predicting and detecting ovulation include continuous measurement of basal body temperature, for example,
Proposed methods include focusing on changes in the chemical properties of secretions and analyzing their components using gas chromatography, and methods of obtaining instructions through chemical reactions using reagents.

However, the analysis method using gas chromatography requires an apparatus that requires complicated procedures, and as a result, it has the disadvantage that only experts can operate it. Furthermore, the device 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, reference numeral 1 denotes an alternating current generator consisting of an astable multivibrator, a positive/negative pulse amplifier, etc., and 2 a plurality of alternating current generators inserted into the detected part of the mammal and for applying alternating current to the detected part. electrodes, 3 a level determination device composed of a plurality of voltage comparators, 4 a display device, and this display device 4 connects a light emitting diode or the like to the level determination device 3 to display information according to each level. It is composed of

5 is a power supply battery, 6 is a booster for boosting the voltage up to 8 voltage using an inverter circuit, etc., and 7 is 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. be.

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 screws. 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 electrode 2 and the electric circuit.

Note that the electrode 2 protrudes from the end surface of the tip 9 of the rod-shaped detection section 8 by 0.5 to 4 mm.

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 when using this 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). 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 section 8, and when the electrode 2 comes into contact with the detected section, the isolateral abdominal flow resistance of the detected section is increased. A potential is generated. 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 ovulation can be predicted and detected based on this level.

However, in the device configured as described above, since the electrode 2 protrudes from the end surface of the distal end 9 of the rod-shaped detection section 8, the electrode 2 may come into contact with the vaginal wall, or may not touch the vaginal wall due to the shape of the mammal's vagina.
There was a problem in that the measurement accuracy was not good and the measurement accuracy was not good, as the large value of the measurement value varied greatly by 1.

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 holder for holding the electrodes, a level determination device connected to the electrodes, and a display device operated by the level determination device, A groove is provided, and the electrodes are exposed from the sides of the groove in a facing state. According to this configuration, even if there are irregularities in the vagina, which is the detection area of the mammal, the vaginal wall is not affected. Since the surface of the holder comes into contact with the electrode and the electrode does not come into direct contact with the vaginal wall, vaginal secretions that have entered the groove come into contact with the electrode, so it depends on the shape of the vagina. It is possible to improve measurement accuracy without

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figures 3a and 3b show an embodiment of the present invention. In Figures 3a and 3b, the same parts as those in the device shown in Figure 2 are given the same numbers, and only the differences are noted. explain. In FIGS. 3a and 3b, reference numeral 11 denotes a holder attached to the rod-shaped detection part 8 by screwing, and this holder 1
A plurality of electrodes 2 for applying alternating current to the detected portion are insert-molded in 1. Reference numeral 12 denotes a groove provided in the holder 11, and the electrode 2 is exposed from the side surface of the groove 12 in a facing state. Further, the width of the groove 12 is set to 3 squares or less.

According to the above configuration, even if there are irregularities in the vagina, which is the detection target part of the mammal, the surface of the holder 11 comes into contact with the vaginal wall, and the electrode 2 does not come into direct contact with the vaginal wall. Not,
Since the vaginal secretions that have entered the groove 12 come into contact with the electrode 2, measurement accuracy can be improved regardless of the shape of the vagina. Further, the width of the groove 12 is 3
Since the particles are divided into smaller particles, the vaginal wall does not enter the groove 12, and only vaginal secretions are stored.

FIGS. 4a and 4b show other embodiments of the present invention, and in these FIGS. 4a and 4b, 13 is a rod-shaped detection section 8.
This holder 13 is attached by screwing to the holder 13, and a plurality of electrodes 2 for applying alternating current to the detected part are insert-molded into the holder 13. Reference numeral 14 denotes a groove provided in the holder 13, and the electrode 2 is exposed from the side surface of the groove 14 so as to face each other. In this case, the width of the groove 14 at the portion of the opposing electrode 2 is narrowed to three ornaments or less.

According to the above configuration, even if there are irregularities in the vagina, which is the detection target part of the mammal, the surface of the holder 13 comes into contact with the vaginal wall, and the electrode 2 does not come into direct contact with the vaginal wall. , groove 1
Since the vaginal secretions that have entered the vagina come into contact with the electrode 2, measurement accuracy can be improved regardless of the shape of the vagina. Furthermore, the exposed surfaces of the electrodes 2 can be easily cleaned because the width of the groove 14 other than between the opposing electrodes 2 is wide.

Effects of the Invention As described above, according to the present invention, a groove is provided in the holder that holds the electrode, and the electrode is exposed from the side surface of the groove in a state where it faces the detected part of the mammal. Even if there are irregularities in the vagina, the surface of the retainer will come into contact with the vaginal wall, and the electrode will not come into direct contact with the vaginal wall, and vaginal secretions that have entered the groove will be absorbed by the electrode. As a result, measurement accuracy can be improved regardless of the shape of the vagina.
