Abstract:
1. A biochip, comprising: a blood collection bag; a plug made from flexible material which airtightly closes an opening of the blood collection bag; said blood collection bag having formed in sequence from one end of said blood collection bag to another end: a collection block directly connected to said plug; a preprocessing block in communication with said collection block, a junction in communication with said preprocessing block, wherein the junction includes a substrate having a plurality of probes arranged in arrays, a pocket formed on a side of said preprocessing block in which solution is encapsulated and said pocket is in communication with said preprocessing block via a passage; wherein said blood collection bag is formed of compressible material; wherein said collection block, preprocessing block, pocket, and junction are positioned so that compression directed from said collection block toward said preprocessing block causes blood to flow from said collection block through said communication to said preprocessing block, and simultaneously said compression causes the solution encapsulated in said pocket to flow into said preprocessing block and further flows said blood and solution in said processing block through the communication with the junction; wherein said passage is formed at a furthest downstream position of the pocket.
