Document Type and Number:
WIPO Patent Application WO/2022/065119
Kind Code:
A1
Abstract:
Provided is an inspection chip with which it is possible to simplify a complex channel switching structure. An inspection chip 1 comprising: a chip body 2 having a specimen introduction channel, an adsorption channel including an adsorption part, a first waste liquid channel, a recovered liquid introduction channel, and a detection channel including a detection part; and a rotary valve 3 attached to the chip body 2 so as to enable rotation about a rotary axis. The rotary valve 3 has a plurality of connection channels. The plurality of connection channels are positioned so that when the rotary valve 3 rotates about the rotary axis, the rotary valve 3 can assume at least: a first state in which the specimen introduction channel, the adsorption channel, and the first waste liquid channel connect so as to be provided in the stated order from the upstream side; and a second state in which the recovered liquid introduction channel, the adsorption channel, and the detection channel connect so as to be provided in the stated order from the upstream side.
