Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a detection device for predicting ovulation when performing artificial insemination in the field of livestock farming.

Configuration of conventional example and its problems The conventional method of predictive detection of J11 eggs is as follows:
In addition to continuous measurement of basal body temperature, for example, there are methods that focus on changes in the chemical characteristics of secretions that occur before ovulation and analyze their components using gas chromatography, or methods that use reagents to generate instructions through chemical reactions. One method has been proposed to obtain it.

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

The method of obtaining by changing the pH due to chemical reaction requires handling.
It is difficult to judge the instructions, and it is difficult to judge the color change etc. with PH paper.
ζ It is difficult to judge. PH1-1 is an expensive device and has the disadvantage of poor accuracy as a single egg detection device.

As shown in FIG. 1, an electrode 101 is inserted into the vaginal orifice of a mammal to be detected.
The predictive detection device configured on the side of 02 is also a conventional example, but by collecting urine etc. from the urethral opening near the vaginal opening,
The measurement accuracy is low and, in practice, there is a large variation.

Purpose of the Invention The present invention solves these conventional problems and improves operability as a compact and handy type. The object of the present invention is to provide a low-cost and highly accurate ovulation detection device that does not deteriorate measurement accuracy due to urine etc.

Structure of the Invention The ovulation prediction and detection device of the present invention is operated by an alternating current generating means, a plurality of electrode sections for applying alternating current to a detection target section, a level determining device connected to the electrode section, and the level determining device. It consists of an electrical configuration with a display device, a detection unit with an electrode provided at the tip of a rod, and a configuration covered with a thin film cover to prevent the electrode from becoming dirty.

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

2 and 3 show the electrical configuration of the ovulation prediction and detection device. Reference numeral 1 designates an alternating current generating means consisting of an astable multi-by-break-9 positive/negative pulse amplifier, 2 an electrode for applying alternating current to the detected part, and 3 an isolateral flow resistance of the detected part.

Reference numeral 4 denotes a level determination device composed of a plurality of voltage ratio 11R devices, and 6 is a display device, which is configured to connect a light emitting diode or the like to the level determination device and display information according to the level.

Reference numeral 6 denotes a power supply battery, 7 a booster for increasing the external voltage at a necessary voltage level using an inverter circuit, etc., and 8 a voltage comparator connected to the power supply battery 6, which is used to check voltage drop of the power supply battery. Reference numerals 9 and 10 indicate operation switches, and when checking the voltage, the check switch 9 is turned on, and when determining the level, the level switch 10 is turned on.

FIG. 4 shows the structure of the main body including the display device 6 and operation switches 9 and 1°, and FIG. 5 shows details of one detecting section.

In FIG. 4, 11 is a rod-shaped detection part, 12i is a main body incorporating an electric circuit, and 13 is a mounting base for holding a polyethylene bag 14 into which the rod-shaped detection part 11 is inserted.
1 so that it can slide freely. 15 is a polyethylene bag 14
The number of screws 16 is a pectoral muscle plate with several screws at the mounting screws 16.

In FIG. 4, reference numeral 2 denotes the electrode described above, which is made of corrosion-resistant gold wood. Reference numeral 17 is a base for fixing several electrodes attached to the rod-shaped detection part 11, and reference numeral 18 is a lead wire for connecting the electrode 2 and the electric circuit. The operation will be described below.〇The rod-shaped detection part 11 covered with a polyethylene bag 14 is inserted into the vagina 19.
Insert inside. Since the depth of the vagina can be estimated in advance, the length A of the polyethylene bag 14 is set to a length of % to % of L with respect to the length of the vaginal opening 20 and the chest bottom 21.

When the rod-shaped detection part 11 is inserted and the chest plate 16 comes into contact with the vaginal opening 20, the polyethylene bag 14 is pushed against the electrode fixing base 17, and the electrode 2 comes off from the covering at the tip and is exposed to the inside of the vagina 19. Preparations for the electric resistance to be constant by i)+1 are completed.

When the electrode 2 contacts the chest base g21 as shown in Fig. 6,
When the level switch 10 is pressed, the positive and negative pulses generated by the AC generator are transmitted to the electrode 2 fixed to the tip of the rod-shaped detection part 11.
The electric potential generated by the isolateral flow resistance 3 of the detected part of the chest bottom 21 is applied to the level determination device 4, and the output causes the light emitting diode constituting the display device 6 to emit light according to the level. Ovulation can be predicted and detected based on the level.

This device integrates a rod-shaped detection section 11 and a main body 12,
Since the electric circuit is housed within the main body, it can be made smaller, lightweight, and easy to operate.

Furthermore, since the rod-shaped detection part 11 is made of flexible material such as polyethylene or hard polyethylene, the detection part 11 is not inserted into the womb of the mammalian subject during use. Therefore, even if the animal moves or raises itself, the detection section can be bent gently, so safety 111: is ensured.

This is the installation base 13 to which the polyethylene bag 14 is attached. (=1 screw 16) The vaginal patch plate 16 can be attached to the main body 12 using a fastener 4th for easy storage.

Effects of the Invention As is clear from the above embodiments, the ovulation detecting device d1 of the present invention is small and easy to operate, and can be manufactured and provided at low cost.

By covering the rod-shaped detection part and the electrode with a thin film cover, urine from the urethra near the vaginal opening (=J) can reach the electrode in a clean state at the bottom of the chest without getting wet. This allows for highly accurate measurements.
