Hereinafter, a suction adapter according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The aspirator adapter according to the present invention is a device capable of adjusting a suction force for suctioning and removing other laboratory liquids including a cell culture medium interposed between a suction pipe installed in an electric motor and a suction device such as a pipette tip.

1 and 2, the suction adapter according to the present invention includes an adapter body 100, a flow pipe 110, a valve structure 200, and a driving unit 300.

The flow path tube 110 is installed inside the adapter body 100 so as to communicate with a suction pipe connected to a sound pressure source such as an electric motor and a pipette tip. In addition, the valve structure 200 opens and closes the flow pipe 110 to adjust suction force inside the flow pipe 110, and the driving unit 300 drives the valve structure 200.

The adapter body 100, the suction pipe (not shown) is in communication with the flow pipe 110, the suction pipe connecting portion 120 is formed protruding at one end, the other end of the suction mechanism (not shown) ) Is attached to the suction mechanism connecting portion 130 is detachably connected.

The flow path tube 110 is provided inside the adapter body 100 to communicate with the suction pipe and the suction mechanism, and is made of an elastic material such as rubber or synthetic resin. The flow path tube 110 is repeatedly deformed and restored by the cam motion of the valve structure 200, thereby adjusting the opening ratio of the flow path to open and close the flow path tube 110.

The valve structure 200 opens and closes the flow pipe 110 by a cam motion, and includes a cam member 210 and a protrusion 220.

The cam member 210 has a cam profile for compressing the flow pipe 110 and is rotatably coupled to the inside of the adapter body 100.

The protrusion 220 is protruded to the inside of the adapter body 100 to press-close the flow pipe in correspondence with the cam member 210. The flow path tube 110 is deformed and opened and closed by a load due to the rotation of the cam member 210 in a state supported by the protrusion 220.
