Rotary integrated micro-device for gene diagnosis

A genetic diagnosis chip comprising one or more unit processing parts, wherein the unit processing part includes:

• a pretreatment section, formed on a surface of the genetic diagnosis chip, that loads a sample and performs a pretreatment process on a target material in the loaded sample;
• and
• a distribution section, formed on the surface, which is located radially outward from the pretreatment section and in which the target material pretreated through the pretreatment section is distributed and detection of the distributed target material is performed,
• wherein the pretreatment section includes:
• a sample loading section, formed on the surface, that loads the sample;
• a capture channel which captures the target material from the loaded sample, the sample loading section being formed on the capture channel;
• a washing liquid storage section, formed on the surface, which is located radially inward from the capture channel to communicate with the capture channel and in which a washing liquid for washing materials excluding the target material captured in the capture channel is stored;
• and
• a delay section formed on the surface and provided between the capture channel and the washing liquid storage section and configured to delay passage of the washing liquid so that the washing liquid reaches the capture channel later than the sample,
• wherein the delay section includes:
• a delay chamber in which the washing liquid that is headed toward the capture channel from the washing liquid storage section is stored;
• and
• a delay channel which is provided between the delay chamber and the capture channel and allows the washing liquid stored in the delay chamber to be discharged to the capture channel when an amount of the washing liquid is greater than or equal to a predetermined amount,
• wherein the delay channel comprises:
• a first delay path extending radially inward from an outlet of the delay chamber;
• and
• a second delay path extending radially outward from an end of the first delay path, the first delay path and the second delay path being aligned to let the washing liquid flow in opposite directions to each other, and
• wherein a length of the first delay path with respect to a radially inward direction corresponds to a discharge level of the washing liquid stored in the delay chamber, such that the washing liquid stored in the delay chamber is configured to be discharged when having reached the discharge level or more.
