DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing a probe 1 used in the labor alarm system of the present invention. The shape and size of the probe 1 differ depending on the animal species, but the description will be given below using a cow as an example. A temperature sensor 2 for detecting the temperature is provided inside the probe 1. The temperature sensor 2 is, for example, a platinum resistance temperature detector. An outer cylinder 3 having a predetermined diameter is provided at the tip of the temperature sensor 2. The outer cylinder 3 has a diameter that allows it to be inserted into the vagina 30 of a cow described below and does not easily fall off, and the tip portion 3a is formed in an arc shape. A filling material such as resin is provided inside the probe 1 to fix the temperature sensor 2.

Further, as shown in the side sectional view of FIG. 2, the probe 10 may be constructed such that an auxiliary plate 7 having the above-mentioned predetermined diameter is provided coaxially with the temperature sensor 2. The auxiliary plate 7 has a screw groove 2a formed on the outer periphery of the temperature sensor 2.
The screw hole 7a is provided by screwing. As shown in the plan view of FIG. 3, a cut portion 7b is symmetrically provided in a part of the circumference of the auxiliary plate 7, so that the insertion can be facilitated and the fall can be prevented.

Next, FIG. 4 is a block diagram showing an electric circuit configuration of the labor alarm system. The temperature signal from the temperature sensor 2 is input to the comparison unit 16 of the transmission unit 15. The setting signal from the setting unit 17 is input to the comparison unit 16, and the temperature of the temperature signal of the temperature sensor 2 is compared with a predetermined set temperature. When the set temperature is lower than the body temperature of the cow, the set temperature is set to a temperature higher than the outside air temperature and lower than the body temperature of the cow, for example, and the comparison unit 16 outputs the detection signal when the temperature signal is lower than this. When the outside air temperature is higher than the body temperature of the cow, the temperature between the outside air temperature and the body temperature of the cow may be set as the set temperature. That is, the set temperature may be a predetermined difference from the body temperature of the cow, and the detection signal may be output when the temperature signal exceeds this.

The comparison section 16 may be so constructed as to monitor the temperature change of the temperature sensor 2 over time and output a detection signal at the time when a point where the temperature change is rapid is detected. The transmission unit 18 receives the output of the detection signal and transmits the transmission signal at a predetermined frequency via the built-in antenna. These temperature sensors 2
The transmitting means 15 is provided in the cow as described later and is operated by the battery.

The receiving means 20 is installed at a place apart from the cow and where the livestock owner is. The receiving means 20
It is installed at an arbitrary distance that the radio wave of the transmission unit 18 of the transmission unit 15 can reach, for example, about 10 to 100 m in practical use. The receiving unit 21 receives the outgoing signal transmitted from the transmitting unit 15 and activates the alarm unit 22. The alarm means 22 outputs an alarm signal from the notification section 23 by voice or an automatic dial section 24 by switching settings such as switches in advance.
By this, a telephone connection is made to another location via the telephone line 25. This automatic dial section 24 is a pager 26
This telephone number may be configured to be connected by telephone so as to call. The receiving means 20 operates using a commercial power source.

As shown in FIG. 5, the probe 1 is installed at a deep part of the vagina 30 of the cow (a position deeper than the outer urethral opening 31) so as not to interfere with the urination behavior of the cow. To do. The cord 5 of the temperature sensor 2 goes out of the body through the vulva and is connected to the transmitting means 15. The transmission means 15 is fixed to the base of the tail 34 of the cow by the belt 32. The base portion of the tail 34 does not move and is a suitable place for fixing the device. Here, the cord 5 has a predetermined length, and has a length that allows the sensor 2 to be discharged outside the body at the time of delivery, which will be described later, and is configured to detect the ambient atmospheric temperature.

Next, the operation of the present apparatus will be described along with the progress of parturition of the animal. The course of labor varies with each animal,
Take a cow as an example.・ Open period: The cervical canal is expanded by the fetus after the onset of labor.
A period of unbounded transition from the uterus to the vagina, usually 3 in cattle
~ 6 hours, but there are individual differences. At this time, the temperature sensor 2 is in the vagina 30, and the device does not operate.

・ Production period As shown in FIG. 6, the uterine ostium is fully opened, and the fetus 33 is the vagina 3
Appear from 0 outside the vulva. At this point, the probe 1 is discharged outside the vagina. The probe 1 discharged to the outside of the vagina outputs a detection signal to the transmission unit 18 when the temperature signal of the temperature sensor 2 drops below the set temperature. The transmitter 18 wirelessly transmits the signal via the built-in antenna. Then, in the receiving means 20 at the remote place, the alarm means 22 is activated to notify the livestock owner of the start of calving, and the livestock owner can quickly move to the place of the livestock.

Thereafter, the fetus 35 ruptures (primary rupture and secondary rupture), the amniotic fluid slips on the birth canal, and the fetus 35 is delivered. The time required for this production period is 1 to 3 hours. As described above, this device is a device for issuing an alarm immediately before the delivery of the fetus (before the water is broken) in the course of delivery of the animal, and the fetus is delivered about 1 to 2 hours after the alarm.

Further, the cord of the probe 1 has a length that allows it to be grounded on the ground, and the sensor is composed of a pressure sensor for detecting impact, so that it is detected that the pressure sensor has fallen to the ground prior to delivery. An alarm may be output, and even in this case, the livestock owner can accurately know the delivery time as in the above embodiment.

In the above embodiment, the probe 1 and the transmitting means 15 are connected by the cord 5 and provided at different positions. However, the transmitting means 15 is provided inside the probe 1, for example, inside the outer cylinder 3. It can also be configured.

[0020]

According to the present invention, at the time of delivery of the animal, the sensor is discharged to the outside prior to the fetus, and the temperature change at this time is detected and wirelessly transmitted to a remote place. It has an effect that the start can be accurately and promptly known, witness of delivery can be ensured, and safety can be improved. Further, if the receiving means is configured to further call the pager as an alarm output, the delivery time can be known at a position further away.
