Description

[Detailed Description of the Invention] Industry-1-Field of Application The present invention is applicable to 4.1j in the field of livestock farming, etc. Used to increase the probability of pregnancy when performing yu insemination.

There is one related to a predictive detection device for ovulation in mammals.

The structure of the conventional example and its problems.
7 Wife and 1. In addition to continuous measurement of basal body temperature, for example, there are methods that focus on changes in the chemical properties of substances that occur before ovulation and analyze their components using gas chromatography. A method of obtaining an instruction through a chemical reaction using a reagent has been proposed2.

However, Gas Chroma! - The wisdom is that the graphical analysis method requires a device 6 that requires complicated procedures and can only be operated by experts. It's a long time, the kesa [1
``'r Hakushu Body High (ilTi).

Similarly, methods for obtaining instructions through chemical reactions are difficult to handle! ! IfI L, <The 'I' and iJ constants of the instructions also had the disadvantage that it was difficult to judge them based on the judgment of color changes, etc.

OBJECTS OF THE INVENTION The present invention solves these conventional problems, and provides an ovulation prediction and detection device that is miniaturized, has improved operability as a handy type, and is designed to reduce costs.

Structure of the Invention The ovulation detection device of the present invention includes an alternating current generating means, a plurality of electrodes for applying alternating current to a detected part, a level determining device connected to the electrodes, and a display device operated by the level determining device. The level determination device has an electrical configuration including means for varying a reference voltage, and the rod-shaped detection member provided with electrodes is configured to be detachable from the main body housing the electric circuit.

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

The electrical configuration of the present invention is shown in FIGS. 1 and 2, in which 1 is an astable multivibrator, 9 is an alternating current generating means consisting of a positive/negative pulse amplifier, etc., and 2 is an alternating current generating means that is 3 is the isolateral flow resistance of the detected part. 4 is a level determination device constituted by a plurality of voltage comparators, which determines the level of the potential at both ends of the isolateral flow resistance 3. 5 is a switch for switching the reference voltage of the level determination device 4, and 6, 7.8 is a series-connected resistor group that generates the reference voltage.Depending on the 91 dH level,
This is a display device consisting of a light emitting diode or the like that emits light, and the user can use this display device to predict and detect ovulation.

Reference numeral 10 denotes a power source battery, which is boosted at a necessary voltage level by a suction device including an inverter circuit 11 and used as a power source. Reference numeral 12 denotes a voltage comparison device connected to the power battery, and is used to check the voltage drop of the power battery. 13.
14 is an operation switch; when checking the battery voltage, switch 13 is turned on; when determining the level,
Turn on switch 14.

3 to 5 show the structure of the main body of this embodiment. Reference numeral 15 denotes a rod-shaped detection portion in which an electrode 2 is disposed on a tip member 16, and is fastened to the main body 18 at a fastening portion 17 at the base. has been done.

As shown in FIG. 4, the fastening portion 17 has a socket portion 20 fixed to the main body 18 with screws 19. On the outer periphery of the socket portion 20, a cover 2 at the base of the rod-shaped detection portion 15 is provided.
The screw to be screwed into 1 is threaded. Rod-shaped detection part 15
It is fastened to the main body 18 with a tobacco screw. Inside the socket part 20, the connector 23 is attached to the insulating plate 22-4-, and the connector 23 is attached to the boss of the socket 1 and part 20 using the screw 24 of the insulating plate 22. 251; J, Electrode Hi.

It is fitted with the connector 23 (7) and an electrical connection is made. 26 () is a lead wire and is connected to the electrode 2 (10).

51'; A is an enlarged sectional view of the rod-shaped detection part 15;
The electrode 2 is screwed onto the rod-shaped detection part 15 and the electrode 2 is screwed onto the tip member 16.
1st place.

To explain the operation in the above configuration, AC generating means 1
The positive and negative generated ζζ soot is placed at the tip of the rod-shaped detection unit 16 and applied to the electrode 2. t:, 1Vtj 2i
j.

The electric potential generated by the tongue-like direct current resistor 3 of the detected area is applied to the detected area at the base of the chest in advance, and is applied to the level judgment device 4, and the output of this is applied to the level determining device 4. The diode emits light and this level allows the user to perform predictive detection of 4-1 eggs.

f -1', the value of bamboo grain 3 is approximately 200 Ω for raw material using the electrode of this example, and 350 Ω for pig material.
and the fΦ class of mammals: the values are different.

Therefore, by switching the reference voltage j1- with the switch 5, making it removable, and replacing the rod-shaped detection part, predictive detection of cane eggs of I and R class mammals can be performed with one device. Effects of the Invention As is clear from the above embodiments, the ovulation prediction and detection device of the present invention is small and has good operability, and can be manufactured and provided at a low cost.

First, the reference voltage of the level determination device is configured to be variable.The predictive detection of cane eggs of multiple scale mammals can be performed with a single device.
