Abstract

The invention relates to a sampling capsule endoscope capable of being automatically sealed. The sampling capsule endoscope comprises a capsule shell, a sealing plug, a needle tube, a partition plateheater, a heating ring, springs, a heating-fusing catheter, a capsule controller, a capsule sensor, a capsule support plate and a needle tube mounting bracket, wherein the capsule shell comprises an electric control device cavity, a collecting device cavity and a sealed sampling cavity, the electric control device cavity and the collecting device cavity are partitioned by the capsule support plate, the collecting device cavity and the sealed sampling cavity are partitioned by the sealing plug, a sampling hole is arranged in the capsule shell, the capsule support plate is provided with a catheter communicating with the sampling hole, the capsule controller and the capsule sensor are arranged in the electric control device cavity, and the partition plate heater is fixed on the inner wall ofthe collecting device cavity. For the sampling capsule endoscope capable of being automatically sealed, the active digestive tract fluid sampling can be completed, meanwhile, after the sampling is finished, samples in a sampling pond are effectively isolated, so that leakage and pollution are avoided.

Description

technical field [0001] The invention relates to the technical field of capsule endoscopes, in particular to a self-sealing sampling capsule endoscope. Background technique [0002] Before the present invention was proposed, the literature Gu and Gu, 1996 ("Ingestibel Gastrointestinal Sampling Devices: State-of-the-Art and Future Directions"), used some special materials to seal the vacuum lumen in the capsule, in specific digestive tract fluid , these plugs degrade, thereby drawing foreign material into the lumen. The design of this document uses degradable materials as triggers. The disadvantages of this design form are: first, the controllability of trigger sampling timing is poor; second, the sampling target is limited by the properties of degradable materials, and it is necessary to know the properties of the target liquid in advance , choose appropriate degradable materials; third, the sampling hole cannot be sealed again after opening, and the sample is easy to leak o...
