The animal bio-signal measuring device of the present invention comprises a measuring instrument body, a non-specific wall portion of an animal nasal cavity A first fixture connected to and fixed to the measuring instrument body at the other end, One end of the specific wall of the nasal cavity being pressed and fixed to the other end of the first fixture, A second fixture connected to the other end so as to be rotatable with the measuring instrument body, And one end of the second fixture are inserted into the nasal cavity of the animal, and the first fixture and the second fixture 2 When the distance between the fixtures is adjusted to narrow the distance, the first fixture and the second fixture The specific gravity of the animal is pressed against both sides of the wall, and the bio-signal measuring device is fixed to the animal , And when the fixture is widened, the bio-signal measuring device is simply removed from the animal And at least one of the first fixing portion and the second fixing portion A body signal measuring sensor is mounted on the body, And an animal bio-signal measuring device having a measuring part for measuring a bio-signal by analyzing the call do. According to the present invention as described above, the measurement sensor is tightly fixed to the specific gravity barrier wall in the nasal cavity To increase the accuracy of the measurement and to ensure that the animal is stable It is possible to fix it as easily as possible, to increase the ease of mounting and detachment, Speeding up of the business can be achieved. Also, in terms of usability, It has the effect of enhancing the safety and the reliability of the apparatus without adding harm.본 고안의 동물생체신호측정기는, 측정기 몸체와, 동물 비강의 비중벽 일측에 압착되는 일단과, 타단이 측정기 몸체와 연결 고정된 제 1 고정구와, 상기 동물비강의 비중벽 타측에 상기 제 1 고정구의 일단과 마주보며 압착 고정되는 일단과,타단이 상기 측정기 몸체와 회동되도록 연결되는 제 2 고정구와, 상기 제 1 고정구및 제 2 고정구의 일단들이 동물의 비강내에 삽입이 되고, 상기 제 1 고정구 및 제2 고정구의 사이의 거리를 조절하여 거리를 좁혔을 때 제1 고정구와 제 2 고정구가동물의 비중벽 양쪽을 마주보고
