Problems solved by technology

[0006] First, the technical problem to be solved by the present invention is that the livestock gastrointestinal electrometer is expensive and limited by livestock environmental factors, which solves the problem that it is not conducive to measurement and carrying. The measurement of livestock routine physiology and the diagnosis of digestive tract diseases can only rely on Veterinary workers have explored that under normal circumstances, accurate gastrointestinal electrometry instruments are expensive and have strict environmental requirements. It is ideal for measuring human gastrointestinal electrometry. Due to the influence of price and environmental factors, it is not suitable for measuring livestock;
[0007] Second, the problem to be solved by the present invention is that it is more inconvenient to fix the electrodes due to the difficulty brought by the use of the gastrointestinal electrometer by the livestock, and the livestock is disturbed during the fixation process, and the measured gastrointestinal electrical characteristic value does not reflect its true value;
[0008] Third, the problem to be solved by the present invention is that the voltage of gastrointestinal electrophysiology is extremely weak on the body surface, and the measurement of the instrument is very easily disturbed by the external electromagnetic field, the stability of the voltage, and the electronic components of the instrument itself. The sum and amplitude change greatly, and the result cannot be judged correctly;

Embodiment 1

[0027] See figure 1 This specific implementation is implemented by adopting the following technical solution, which includes a pressure sensor 1, which is connected to a signal amplifier 4 through a first data line 6, and the signal amplifier 4 is connected to a data acquisition through a second data line 7 The card 3 is docked, and the data acquisition card 3 is provided with a USB interface, and the USB interface is docked with the computer 8 through the third data line 5;

[0028] The end of the pressure sensor 1 is docked with the probe 2, the end of the probe 2 is installed with a water seepage stone, and the pressure sensor 1 is docked with the signal amplifier 4;

[0029] The pressure sensor 1 adopts a pressure sensor with a range of 0Kpa-60Kpa, an accuracy of 0.1%-0.5%, and a probe diameter of 2mm-4mm.

[0030] The accuracy of the signal amplifier 4 is 0.1% to 0.5%, and the signal amplifier uses a power supply of 24VCD and an output voltage of 0-5VDC.

Embodiment 2

[0032] An operating method of a device for measuring physiological tension in the stomach of livestock specifically includes the following steps:

[0033] 1). First coat the outside of the pressure sensor 1 and the probe 2 and the first data line 6 with petroleum jelly;

[0034] 2). Fix the test animal, and slowly send the pressure sensor 1 and the probe 2 from the animal's nasal cavity through the pharynx and esophagus into the stomach for measurement;

[0035] 3) The data measured by the pressure sensor 1 is recorded by the computer 8;

[0036] 4). The computer 8 has a driver corresponding to the pressure sensor 1.

[0037] The signal amplifier 4 described in this embodiment is purchased from Xi'an Hangdong Instrumentation Co., Ltd., model CYY-FDQ;

[0038] Signal amplifier 4 input signal output 0~5VDC, power supply 24VDC. According to the requirements, the data acquisition card 3 was purchased from Xi’an Hangdong Instrument Co., Ltd., model CYY;

[0039] Among them, the data acquisiti...

Embodiment 3

[0044] The experiment was aimed at Tibetan sheep. The pressure sensor 1 was put into the rumen of the sheep with a gastric tube, connected to the computer, 5 minutes later, after the sheep was quiet, the rumen tension was measured.
