Specifically, the material of the shell 1 can be the same as that of the shell in the existing sampling capsule, and can also be designed additionally, and the material of the shell 1 only needs to be harmless to human body and can not be corroded by digestive juice.

Meanwhile, the length of the sampling capsule is within 30mm, such as 27mm, and the diameter is within 12mm, so that the sampling capsule can well enter any part in the digestive tract to collect digestive juice. It will be understood that the length and diameter of the sampling capsule referred to above refer to the length and diameter of the housing 1.

The sampling device part 12 is provided with an outer sample inlet 21, and the sampling channel 2 is connected to the outer sample inlet 21.

The sampling capsule in still be equipped with sampling pump 3 in the

collection device portion

12, 3 one end of sampling pump is equipped with inlet 31, inlet 31 with sampling channel 2 is connected, and the other end is equipped with liquid outlet 32. The sampling pump 3 is equipped with the terminal surface of liquid outlet 32 with the inner wall of casing 1 encloses to establish and forms and holds chamber 4, hold the intracavity 4 be equipped with connect in the sampling container 5 of liquid outlet 32.

Specifically, the sampling pump 3 is a one-way liquid pump with a certain flow parameter, and after the sampling pump 3 starts to work, the digestive juice can be pumped into the pump body through the external sample inlet 21 and the sampling channel 2, and then is conveyed into the sampling container 5 through the liquid outlet 32. According to the flow parameter of the sampling pump 3 and the volume parameter of the containing cavity 4, the working time required for collecting full digestive juice can be calculated.

Sampling is carried out through the sampling pump, can select to open or shut off at any time to can realize that the sampling capsule samples in a plurality of places in the alimentary canal, close after the sampling 3 come to cut off sampling channel 2 can prevent to gather liquid and be contaminated.

Further, sampling channel 2 with be interference fit between the inlet 31, or additionally be equipped with seal ring, in order to guarantee sampling channel 2 with leakproofness between the inlet 31, thereby guarantee sampling pump 3 is carrying out the drawing liquid during operation, and the flow parameter can exert the accuracy.

The electronic control equipment part 13 is internally provided with a control module 6, in the embodiment, the sampling pump 3 is electrically connected with the control module 6 through a lead 7 penetrating through the sampling channel 2, the control module 6 can control the working state of the sampling pump 3, and the control module 6 comprises a wireless transmission module, a processor, a battery and the like which are in communication connection with an external processing terminal, so that the sampling pump 3 can be controlled to be started or stopped by inputting a signal for starting or stopping to the control module 6. In other embodiments, the sampling pump 3 and the control module 6 may also be connected in communication by a wireless module.

Furthermore, a through hole through which the lead wire 7 can pass is formed in the wall of the sampling channel 2.

In the present embodiment, the sampling vessel 5 is a balloon having an elastic wall. When the air bag is installed, the air in the air bag is firstly exhausted and then installed on the liquid outlet 32, namely, when the sampling capsule enters the human body, the air bag is in a contracted state, the air bag is gradually filled with digestive juice along with the inflow of the digestive juice, and the wall of the air bag is expanded to a certain degree.

Furthermore, the elastic wall of the air bag is a thin wall similar to the wall of the balloon, and the material is latex or rubber and the like. Adopt the gasbag is as sampling container 5, its simple structure, simple to operate cooperates sampling pump 3 can realize the sampling operation easily, and need not to realize the sampling through the siphon effect through setting up sealed sampling storehouse.
