Abstract

A pretreatment device applied in sampling and providing a reaction space for biochemical reaction is disclosed. The pretreatment device includes a quantitative sampler being capable of collecting a constant volume of a sample; a devastating device having a hollow cylindrical structure coupled to the quantitative sampler to damage a thin-film like protective membrane of the quantitative sampler such that the reaction reagent flows out of the reagent container; a reaction device having a tubular structure and providing the reaction space for biochemical reaction of the reaction reagent and the sample; a hollow ring-shaped structure to position and stable the connection of the devastating device and the quantitative sampler with the hollow ring-shaped structure being coupled to the reaction device; and an anti-drain device preventing the reaction reagent and the sampler from flowing out before the biochemical reaction is completed.
