うなことが行われている。2. Description of the Related Art It is required to measure electrocardiograms or electromyograms of wild animals or breeding animals as well as humans, and several measuring devices have been proposed. For example, in the "heart rate monitor for horses" described in Japanese Patent Application Laid-Open No. 5-212005, electrodes are arranged along the inner surface of the abdominal band for fixing the saddle, and the electrodes are mounted on the horse body by attaching the abdominal band to the horse body. To detect the electrical signal induced by the electrodes and calculate the heart rate from the electrocardiogram signal of the horse. The reason why the electrodes are attached to the inside of the abdominal band is that a horse is a timid animal, and it is difficult to attach electrodes for measuring an electrocardiogram. Therefore, even if the electrode is attached to the horse body surface,
By moving nearby muscles from a foreign body sensation or by taking the same action as removing a flies or fly with hind legs or tail,
Because good measurement conditions cannot be obtained, and you may get excited and rampage just by looking at the electrodes, cords, measuring devices, etc. Is being done.

It is not possible to secure contact with the body surface only by pressing the electrode over the body hair as in the related art. To solve the problem, an "electrocardiogram electrode for an electrocardiograph" described in Japanese Patent Application Laid-Open No. 5-200008 has been proposed. this is,
By forming the electrode in a sword-like shape, the object is to secure contact between the electrode and the body surface without being disturbed by body hair or the like.

することもできなかった。However, in the case of using an electrode mounted on the abdominal band or saddle of the above-described harness, only the body surface potential of the abdomen can be measured. Was limited to a specific area and was not sufficient to investigate all circulatory diseases in horses. Furthermore, the inability to measure the electromyogram of the leg, which is important for the life of the horse, prevented the failure of the leg from being detected early.

参考にして動物を治療することもできる。The operation and effect will be described below. According to the first characteristic configuration of the aquarium-type biopotential measurement device according to the present invention, the animal can be positioned at a predetermined position in the aquarium, and the animal can be prevented from moving. An electrical signal such as an electrogram signal can be configured not to include noise generated when an animal moves by moving a muscle. Note that the positioning means itself is movable, and the position of the positioning means is changed depending on the type or size of the animal to be measured. Further, by moving the positioning means, the animal can be positioned at a position where the desired body surface part is close to the electrode, and the potential of the desired body surface part can be measured. Furthermore, when the measurement of the body surface potential is repeatedly performed at intervals (for example, every other day), the location where the positioning means is fixed is set to the same location for each measurement, so that the body surface portion of the animal and the electrode Can be consistent in the relative location of
Reproducible measurement results can be obtained. Furthermore, since an electrocardiogram waveform of an animal, particularly a mammal close to a human, is accurately measured, it can be compared with a human electrocardiogram waveform. As a result, when a characteristic waveform indicating a disease is obtained from an animal other than a human, the animal can be treated by referring to a human treatment method.

できる。Further, since the animal to be measured is temporarily loaded by the water pressure immediately after entering the water tank, the heart rate is generally faster and the respiratory rate is increased. By analyzing the time to return to the same level, the strength of cardiopulmonary function and the state of fatigue can be known.
Furthermore, if the cardiopulmonary function of many horses is examined by the same measurement method, it is possible to obtain information such as the relationship between the worry function and the pedigree.

For example, if a leg has a failure, an unnatural EMG waveform is seen in the EMG of the other leg to cover the leg, and even if it is not visible that the It is possible to detect the possibility that there is a failure. In particular, it is useful in that a leg failure occurring in a horse in which a leg failure leads to a fatal disease can be detected early.

For example, if an animal has a disease in the leg, an abnormal EMG waveform is measured by moving the muscle near the part where pain is felt, and an abnormal EMG is also observed when performing an action to cover the foot with the disease. The waveform is measured.
Usually, before the person in charge of the animal becomes aware of it, the animal itself takes an action showing such an abnormal electromyogram waveform. The disease is detected early and treatment begins.
Although the embodiment in which the electrode is provided on only one leg has been described, the electrodes 3e and 3f may be provided on each of the four legs, and the electromyogram of a specific muscle such as the waist as well as the leg may be provided. The electrodes 3e and 3f may be provided at positions where can be measured. In that case,
The electrodes may be provided so as to sandwich the muscle to be measured.

There may be. In addition, in the case of an animal which is stationary by blindfolding and creating darkness, the blindfolding means or darkening means functions as positioning means. That is, other modifications are possible as long as the animal can be kept still for a certain period of time during which the measurement is performed.

As means for detecting that the animal is stationary, a plurality of pressure sensors are provided on the floor of the aquarium, and means for detecting whether the animal is stationary based on the pressure fluctuation measured by the pressure sensor,
Means for detecting whether or not the animal is stationary by providing a plurality of general optical sensors on the inner wall surface of the aquarium, such as when connecting an animal such as a horse with a bridle as in the above-described embodiment,
Means for detecting whether or not the animal is stationary by monitoring a change in the tension applied to the reins can be used.

Means for correcting the measured signal may be provided. By providing the means for correcting the signal in this way, it is possible to prevent the baseline of the measured electrocardiogram waveform from fluctuating greatly.
