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 storage, etc., particularly to increase the probability of pregnancy during artificial insemination. It is something.

Conventional technology In addition to continuous measurement of basal body temperature, conventional methods for predicting and detecting ovulation include, for example, focusing on changes in the chemical properties of secretions that occur before ovulation and detecting their components. Methods of analysis using gas chromatography and methods of obtaining instructions through chemical reactions using reagents have been proposed.

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. 3 and 4. That is, in FIG. 3, 1 is an alternating current generator consisting of an astable multivibrator, 1 a positive/negative pulse amplifier, etc., 2 is inserted into the detected part of a clear mammal,
and a plurality of electrodes for applying alternating current to the detected portion; 3, a level determination device composed of a plurality of voltage comparators; 4f';
i. A display device. This display device 4 is configured to connect a light emitting diode or the like to the level determining device 3 and display information according to each level.

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

Fig. 4 shows the configuration of the main body of this device, where 8 is a holding tube made of a flexible material such as hard polyethylene, and a tip 9 is attached to this holding tube 8 by screwing. . An electrode 2 for applying alternating current to the detected portion is attached to the tip 9. 10 is a lead wire that connects the electrode 2 and the electric circuit. Note that the electrode 2 is made to protrude from the end surface of the distal end portion 9 of the holding tube 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. 1.
The electrical resistance of the paddle secretion changes, so when using this device, first insert the holding tube 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 AC generating means 1 are applied to the electrode 2 fixed to the tip 9 of the holding tube 8, and when the electrode 2 comes into contact with the vaginal wall, a potential is increased due to the isoinversion flow resistance of the detected part. Occur. This potential is then 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.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, the holding tube 8 does not have sufficient elasticity.
If it is necessary to increase the length of the electrode 2, the measurement point will not be stable, and as a result, the angle at which the electrode 2 hits will change, resulting in variations in measurement values and poor measurement accuracy. was.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an ovulation prediction and detection device with high measurement accuracy.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention consists of a holding tube that holds a plurality of electrodes made of a resin with excellent chemical resistance, and a resin with excellent elasticity inside the holding tube. It is provided so that a holding rod is inscribed therein.

Function According to the above structure, the presence of the holding rod with excellent elasticity makes it possible to provide sufficient elasticity to the holding tube that holds a plurality of electrodes. Even in cases where the length needs to be increased, the measurement point becomes stable, and as a result, measurement accuracy can be improved.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, the same parts as those in the device shown in FIG. 4 are given the same numbers, and only the different points will be explained. That is, in FIGS. 1 and 2, reference numeral 11 is a holding tube made of a resin with excellent chemical resistance such as polyethylene, and a plurality of electrodes 2 are attached to the tip 12 screwed onto the holding tube 11. It's stuck. 13 is the holding tube 11
This is a holding rod located inside the holding rod 13.
is made of elastic resin such as polyurethane, and is provided so as to be inscribed in the holding tube 11 .

In the above configuration, since the holding rod 13 made of elastic resin is inscribed in the holding tube 11 holding the plurality of electrodes 2, the holding tube 11 has sufficient elasticity, and as a result, In particular, even in animals such as cattle, where the length of the holding tube 11 needs to be increased, the measuring points are stable, so that the measurement accuracy is improved. Furthermore, since the holding tube 11 is made of resin with excellent chemical resistance, its durability is improved. Further, the holding rod 13 is provided with a groove 14, and by passing the lead wire 1o of the electrode 2 through this groove 14, breakage of the lead wire 1o is prevented.

Effects of the Invention As described above, according to the present invention, since the holding tube that holds a plurality of electrodes is made of a resin with excellent chemical resistance, its durability can be improved, and the inside of the holding tube can be Since a retaining rod with excellent elasticity is provided inscribed in the retaining tube, sufficient elasticity can be imparted to the retaining tube.
As a result, even in cases where the length of the holding tube needs to be increased, such as in the case of cattle, the measurement points can be stabilized, so that measurement accuracy can be improved.
