In this embodiment, along the folding direction of the flexible sampling bin 7, the holding member 8 includes two magnetic members with different polarities respectively disposed at two opposite ends of the flexible sampling bin 7, so that the flexible sampling bin 7 is held in a folded state by two magnetic members being attracted to each other. After the power unit 6 starts to pump the gas/liquid outside the sampling capsule 100 into the flexible sampling chamber 7, the flexible sampling chamber 7 gradually expands to an expanded state by overcoming the suction force between the two magnetic members. Of course, this is not a limitation.
In a specific embodiment, one of the two magnetic members is a plurality of magnetic particles 81 disposed dispersedly, and the other is a magnet block 82, the magnetic particles 81 are disposed at one end of the flexible sampling chamber 7 far away from the outlet, the magnet block 82 is disposed at the side of the power unit 6, and the plurality of magnetic particles 81 disposed dispersedly at one end of the flexible sampling chamber 7 far away from the outlet have a weaker attraction force, so that the flexible sampling chamber 7 can be maintained in a folded state before the sampling capsule 100 samples, and the flexible sampling chamber 7 is made to easily overcome two of the attraction forces between the magnetic members and gradually unfolded to the unfolded state when the sampling capsule 100 samples.

Specifically, in the embodiment that the holding member 8 is a magnetic member, the detecting unit 9 is a magnetic sensor disposed between two magnetic members, the magnetic sensor senses the sum of the magnetic fields of the magnetic members and the ambient magnetic field, during the process that the flexible sampling bin 7 is gradually filled with the digestive juice and the flexible sampling bin 7 is unfolded, the distance between the magnetic particles 81 and the magnet block 82 is gradually increased, and the magnetic field strength sensed by the magnetic sensor is gradually decreased, so that the degree of unfolding of the flexible sampling bin 7 can be estimated by the magnetic field strength sensed by the magnetic sensor, thereby estimating the collection amount of the digestive juice in the flexible sampling bin 7.
Generally, the magnetic field information fed back by the magnetic sensor is acquired in an environment where a human body is in a static state and no strong magnetic field interference exists around the human body, so that the accuracy of measurement is not affected.
Specifically, in the embodiment where the power unit 6 is hermetically connected to the housing 1 and the magnet block 82 is provided on the second side of the power unit 6, the magnetic sensor is fixed to the first side of the power unit 6.
Furthermore, a through hole (not numbered) and a waterproof and breathable film 72 matched with the through hole are arranged on the flexible sampling bin 7. When the sampling capsule 100 starts sampling, the power unit 6 pumps external gas/liquid into the flexible sampling chamber 7, so that when the flexible sampling chamber 7 is gradually unfolded, the gas entering the flexible sampling chamber 7 permeates out of the flexible sampling chamber 7 through the waterproof breathable film 72, and only liquid is retained in the flexible sampling chamber 7, so that after a period of time, the flexible sampling chamber 7 is filled with liquid digestive juice.
When the flexible sampling bin 7 is in the unfolding state, if the flexible sampling bin meets intestinal pressure fluctuation, such as intestinal pressure is increased, on one hand, under the action of external pressure, external gas/liquid enters the power unit 6 from the sampling port 12, and a channel space in the power unit 6 is squeezed, so that the pressure in the power unit 6 is increased; on the other hand, ambient pressure extrudees flexible sampling storehouse 7 makes flexible sampling storehouse 7 takes place certain folding, and the volume of flexible sampling storehouse 7 reduces, makes pressure in the flexible sampling storehouse 7 improves, makes the pressure balance of the relative both sides in exit makes external liquid can't get into in the flexible sampling storehouse 7, promptly, can not lead to because of ambient pressure fluctuation digestive juice in the flexible sampling storehouse 7 is contaminated.
It can be understood that when the flexible sampling chamber 7 is in the unfolded state and encounters intestinal pressure fluctuation, if the outside has gas, the outside gas can penetrate through the waterproof breathable film 72 to enter the flexible sampling chamber 7, so as to further increase the pressure in the flexible sampling chamber 7, so that the outside liquid cannot enter the flexible sampling chamber 7, that is, the digestive juice in the flexible sampling chamber 7 cannot be polluted due to the external pressure fluctuation.
Further, the present invention also provides a sampling capsule system (not shown), which includes the above-mentioned sampling capsule 100, and an external processing terminal (not shown) cooperating with the sampling capsule 100, specifically, the external processing terminal is in communication connection with the main control chip to control the working state of the sampling capsule 100.
