A quick-connect liquid storage assembly based on the outlet of the air pressure source microflow pump

Abstract

The invention provides a fast-connected liquid storage pipe with an adapter, and relates to reagent filling and fast connecting of an outlet of a pneumatic-supply micro-flow pump drive. The fast-connected liquid storage pipe comprises the adapter and a liquid storage pipe body, wherein the adapter (3) is arranged on the opening of the liquid storage pipe body. A cylindrical pipeline connector (7) is arranged in the center of the adapter (3), a plurality of air ventilation channels (4) are formed around the cylindrical pipeline connector (7), and a thin liquid outlet pipe (10) is connected to the lower end of the cylindrical pipeline connector (7). When the liquid storage pipe body is inserted into a fast-connected connector of the outlet of the pneumatic-supply micro-flow pump, the cylindrical pipeline connector (7) is tightly connected to an internally-connected pipe opening in the fast-connected connector in a butt joint mode. According to the invention, the adapter and the liquid storage pipe body are integrally assembled; the fast-connected liquid storage pipe can be used as a fast-connected connector to be inserted into a connector device, tight butt joint of the pipeline connector in the adapter and the internal pipe opening of a closing part of the fast-connected connector can be achieved, and operation is easy and convenient.

Description

technical field [0001] The invention relates to a quick-connect liquid storage assembly based on the outlet of a micro-flow pump of an air pressure source. It can be used to plug into the quick connector of the outlet of the air pressure source micro-flow pump to realize quick connection and convenient manipulation of reagents. Background technique [0002] As a power-providing device, the micro-flow pump driving device is mainly used to drive the movement of small-volume reagents in the micro-channel, and to control the operation, mixing, assembly, and various biochemical reactions of the reagents on the micro-scale platform. The constant pressure microflow pump driven by the air pressure source uses gas as the power source and working medium to drive the reagent. The traditional micro-flow pump equipment is to install the reagent in the built-in specific container cavity, insert the output tube, install the sealing cap, and then operate it. This loading and unloading met...

For example, the Chinese invention patent application (application number: 201410578210.9; authorized publication number: CN 104329527 A) discloses a straight-through quick connector, which relates to the field of pipeline joints, which can achieve convenient installation and disassembly, good sealing effect, and simple structure. , but the quick connector is generally used as a node of the flow path, and is only used to realize the direct flow in and out of the liquid. Microchannels, especially microflow pump drive equipment, rarely use infusion devices and storage tubes based on quick connectors.
