Title:
QUANTITATIVE STORING AND INJECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/062497
Kind Code:
A1
Abstract:
A quantitative storing and injecting device, comprising a fixed column (1), a barrel (3) provided at the rear section of the fixed column (1), and a plunger (4) inside of and covered by the barrel (3). Provided on a side of the fixed column (1) are sealing ring grooves (2), and provided on top of the fixed column (1) is a through hole (2-1). A hollow tube (3-1) is provided in the barrel (3), the tail end of the hollow tube (3-1) being provided with a puncturing top (3-2) and the central hole of the hollow tube (3-1) being in communication with the through hole (2-1). A reagent compartment (4-1) and a sealing film (4-2) for sealing the reagent compartment (4-1) are provided in the plunger (4). The outer wall of the plunger (4) and the inner wall of the barrel (3) are in close contact, and the inner wall of the plunger (4) and the outer wall of the hollow tube (3-1) are in close contact. The injecting device is a quantitative injecting device suitable for the fields of biology, chemistry, and medicine. To enhance the reagent injection precision of the injecting device, the flow discharge mode for the reagent in the reagent compartment is improved, the reagent residue is reduced, and the sealing ring grooves are provided so as to prevent reagent overflow and to control the regent flow speed and volume. The method for welding the reagent compartment and the sealing film is improved so as to reduce reagent residue due to reagent compartment deformation. The reagent in the reagent compartment is therefore completely discharged into a reaction container, thereby further improving detection precision.
