However, Patent Document 1 is to measure the amount of gas in the rumen, and there is a problem in that it is difficult to distinguish between an increase in gas pressure in the rumen caused by a disease of a ruminant such as dystrophy and an increase or decrease in pressure in the rumen due to contraction of the rumen.

Patent Document 2 (US Patent Publication No. 20090182207) discloses an ingestible pill as a system for monitoring animal characteristics. However, Patent Document 2 only detects the movement of the rumen using an accelerometer provided in the pill coupled to the inner wall of the rumen, and there is a problem that the rumen pressure of the ruminant cannot be measured.

The technology underlying the present invention is disclosed in the following patent documents.

If the interval between the inner surface of the elastic bag 121 and the outer surface of the capsule unit 110 at this time is referred to as a second interval, the second interval may be smaller than the first interval. On the other hand, the degree of contraction of the elastic bag 121 according to the degree of contraction of the rumen 2 may also vary. At this time, the greater the contraction pressure of the rumen 2, the more the rumen 2 can be contracted, and accordingly, the elastic bag 121 can also be contracted more.

4.1.6. Filling liquid 122 according to the second embodiment of the present invention

The filling liquid 122 flows into the decompression chamber 124 from the inner space of the elastic bag 121 when the rumen 2 is contracted, thereby transferring the contracting pressure of the rumen 2 to the inside of the decompression chamber 124 . plays a role The filling liquid 122 may be injected into the inner space of the elastic bag 121 in a predetermined amount at a predetermined density.

4.1.8. Decompression chamber 124 according to the second embodiment of the present invention

The decompression chamber 124 serves to introduce the filling liquid 122 from the outside of the capsule part 110 into the inside of the capsule part 110 so as to measure the contractile pressure of the rumen 2 . The decompression chamber 124 may be built in a predetermined position of the capsule part 110 , and may be connected to the injection tube 123 . On the other hand, the pressure reduction chamber 124 may be formed in the shape of a cylinder so that the piston 125 can operate smoothly. At this time, the surface on which the injection tube 123 is formed among the inner surfaces of the decompression chamber 124 is referred to as a front surface, and a surface opposite to the front surface is referred to as a rear surface.

4.1.10. The elastic body 126 according to the second embodiment of the present invention

The elastic body 126 may include, for example, an elastic spring. Of course, when the elastic bag 121 contracts in conjunction with the contraction of the rumen 2, the elastic body 126 can be contracted so that the filling liquid 122 can be injected into the first region, and the rumen 2 When is expanded and the magnitude of the external pressure applied to the elastic bag 121 is reduced, the filling liquid 122 may include various types of elastic bodies satisfying that it can be elastically restored so that it can be discharged from the first region.

4.1.11. Operation of the decompression unit 120 according to the second embodiment of the present invention

When the rumen 2 contracts, the internal pressure of the rumen 2 increases, so the size of the external pressure applied to the elastic bag 121 from the inner wall of the rumen 2 and the contents accommodated in the rumen 2 also increases.

Accordingly, when the rumen 2 contracts, the elastic bag 121 may contract in conjunction with the contraction of the rumen 2 . At this time, since the size of the capsule part 110 is the same even when the elastic bag 121 is contracted, when the elastic bag 121 is contracted, the size of the space between the elastic bag 121 and the capsule part 110 is reduced. Accordingly, the filling liquid 122 may be injected from the elastic bag 121 into the first region of the decompression chamber 124 . In this case, the size of the first region may increase and the size of the second region may decrease. Also, the elastic body 126 may be contracted.

When the rumen 2 expands, the internal pressure of the rumen 2 can be reduced. Accordingly, the pressure applied to the elastic bag 121, for example, external pressure can be reduced. At this time, the elastic body 126 may return the filling liquid 122 from the first area of the decompression chamber 124 to the elastic bag 121 by providing an elastic restoring force to the piston 125 .

That is, when the rumen 2 is contracted and expanded, the amount of the filling liquid 122 present in the decompression chamber 124 may vary, and the filling liquid 122 is transferred to the piston 124 in the decompression chamber 124 . The applied pressure may vary.

Any one type or a plurality of types of pressure sensors may be used. The type of the sensor unit 130 may be various in addition to this.

The pressure applied by the filling liquid 122 to the piston 125 may be equal to or proportional to the external pressure that the elastic bag 121 receives from the rumen 2 . If the filling fluid 122 knows the pressure applied to the piston 125, the external pressure applied to the elastic bag 121 by the rumen 2, for example, the contraction pressure of the rumen 2, can be made. Accordingly, the sensor unit 130 may measure the pressure applied to the piston 125 to reduce the contraction pressure of the rumen 2 .

The sensor unit 130 may be connected to the control unit 133 through at least one of wired communication and wireless communication. The pressure value measured by the sensor unit 130 may be transmitted to the control unit 133 in the form of an electrical signal.

The operation of the sensor unit 130 may be controlled by the control unit 133 . The sensor unit 130 may receive power required for operation from the power source unit 132 .

The first axis direction may be a long axis direction of the case 141 , and the second axis direction may be a short axis direction of the case 141 . Here, the first axis direction and the second axis direction may be orthogonal to each other. Meanwhile, the shape of the case 141 may vary.

The case 141 may be protected by being surrounded by the sensor units 150 , 160 , and 170a. For example, the sensor units 150 , 160 , 170a may form an outer case or an exoskeleton of the biometric information capsule 100 - 3 , and the case 141 may form an inner case or an endoskeleton of the biometric information capsule 100 - 3 . can do.

Of course, the pressure reducing member 150 may be a pill-shaped member divided into eight divisions along the first axis, the second axis, and the third axis. The third axis may be a predetermined axis orthogonal to the first axis and the second axis.

The pill shape may have a predetermined shape with both ends having a hemispherical shape, a connecting portion connecting both ends having a cylindrical shape, and a hollow interior. Of course, the shape of the pressure reducing member 150 may vary.
