Title:
TWO-FLUID SYRINGE MODULE FACILITATING MIXING
Document Type and Number:
WIPO Patent Application WO/2023/048333
Kind Code:
A1
Abstract:
The present invention comprises: a cylinder housing which has an arbitrary accommodation space formed therein, accommodates at least two types of fluids to be mixed in the accommodation space, and includes at least two insertion holes; a first pressing member which has one side hermetically inserted into one of the insertion holes of the cylinder housing, moves in a first reciprocating motion so that the to-be-mixed fluids accommodated in the accommodation space of the cylinder housing are pressed in the cylinder housing by an external force, and causes the to-be-mixed fluids to flow in the accommodation space due to the first reciprocating motion; a second pressing member which has one side hermetically inserted into the other insertion hole of the cylinder housing, and moves in a second reciprocating motion, which is automatically guided in the opposite direction as the first reciprocating motion, while being pressed inside the cylinder housing at the same time as the to-be-mixed fluids by the first reciprocating motion of the first pressing member; and a mixing unit which is integrated with the cylinder housing to form the accommodation space therewith, interferes with the flow of the to-be-mixed fluids by colliding with the to-be-mixed fluids flowing due to the first reciprocating motion, thereby mixing the to-be-mixed fluids while inducing the mutual agitation of the fluids to be mixed. The one side of the first pressing member and the one side of the second pressing member respectively perform the first and second reciprocating motion alternately and repeatedly so as to generate a backflow of the to-be-mixed fluids with respect to the pressing direction of the first reciprocating motion, thus making it possible to more rapidly and easily mix the fluids to be mixed.
