Detailed Description

The embodiment provides a technical scheme:

as shown in FIGS. 1 to 4, a multi-element incompatible reagent storage device comprises a storage bag 1 for containing reagent liquid, a mixing cylinder 22 for mixing a plurality of reagents, and an opening and closing mechanism. The open end of the storage bag 1 is provided with a closure membrane. The opening and closing mechanism comprises a thimble pricking column 25 for pricking the sealing film and a limiting retaining ring 26 for fixing the thimble pricking column 25. The side end of the mixing cylinder 22 is provided with a fixing ring 220 detachably connected with the open end of the storage bag 1, and the fixing ring 220 is communicated with the inside of the mixing cylinder 22. The spike-stick 25 is slidably disposed in the hollow interior of the fixing ring 220, and the spike-stick 25 is provided with a reagent passage hole for flowing a reagent. One end of the limit retaining ring 26 is provided with an embedding groove which is matched with the thimble spike 25 to be embedded and fixed.

As shown in fig. 4, the opening and closing mechanism further includes an elastic member 23, a first limiting ring 221 is disposed inside the fixing ring 220, a second limiting portion 250 is fixedly disposed on an outer side wall of the thimble spike column 25, one end of the elastic member 23 is fixed to the first limiting ring 221, the other end of the elastic member is fixed to the second limiting portion 250, and a hollow portion of the first limiting ring 221 is adapted to the thimble spike column 25 to pass through. When the thimble spike 25 is restrained and fixed by the retaining ring 26, the elastic member 23 (spring) is in a stretched state.
