Reagent blending device

Abstract

The invention discloses a reagent blending device comprising a liquid preparation bottle and a mixer arranged in the liquid preparation bottle; the mixer comprises a pipe body; a first feeding pipe isarranged on one side of the pipe body; a second feeding pipe is arranged on the other side of the pipe body; the other end of the first feeding pipe and the other end of the second feeding pipe are connected with a transverse pipe, and the transverse pipe is provided with a plurality of connection ports used for injecting reagents; the lower end of the pipe body is provided with an inverted liquid outlet pipe, through holes which are evenly distributed and symmetrically formed are formed in the liquid outlet pipe, and an opening of the liquid outlet pipe communicates with the outside. Different reagents can be introduced into the pipe body through the plurality of connection ports, flow to the opening through the though holes in the liquid outlet pipe, and enter the interior of a liquid preparation tank; the through holes are symmetrically formed, so that the reagents can collide with each other when the reagents flow out so as to achieve the uniform stirring and the blending of the reagents, and thus the problem that the reagents need to be uniformly stirred by using an electric tool during the reagent blending by a conventional liquid blending tank is solved.

Description

technical field [0001] The invention relates to the technical field of biological agent preparation, in particular to a reagent preparation device. Background technique [0002] The liquid mixing tank, also known as the preparation tank and the blending tank, is a mixing and stirring container for mixing one or several materials according to the process ratio. It is mainly used in dairy, chemical, food, beverage, pharmaceutical, pharmaceutical and other industries. It is the most widely used, and has different names according to different uses. It is used in pharmaceutical liquid preparation systems, often called liquid preparation tanks, concentrated preparation tanks, thin preparation tanks, stainless steel liquid preparation tanks, sanitary grade liquid preparation tanks, and injection preparation tanks. According to different stirring forms, there are magnetic stirring liquid mixing tanks, stirring blade type liquid mixing tanks, and buffer liquid mixing tanks; according...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the liquid mixing tank used for biological reagents is the preparation of biological reagent liquids. The liquid mixing tanks for biological reagents in the prior art mainly include tanks and stirring devices in the tanks. Most of them are mechanical stirring, which increases energy consumption. It is easy to form a vortex when stirring, resulting in a drop in stirring efficiency
