<p>Disclosed are a sampling needle automatic washing apparatus and method therefor. The sampling needle automatic washing apparatus comprises: a sampling needle (3) and a connection mouth (2), a sampling needle movement channel provided within the connection mouth (2), a first sealed node (5), a first cavity (8), a second sealed node (6), a second cavity (9), and a connection mouth housing (1)-connecting sealed node (12) sequentially provided at the sampling needle movement channel, a liquid inlet channel (13) provided below the first cavity (8) and in communication with the first cavity (8), and a liquid outlet channel (10) provided at the connection mouth (1)-connecting sealed node (12) and in communication with the sampling needle movement channel. Employment of the automatic washing apparatus and method allows for the inner wall and the outer wall of the sampling needle and the connection mouth to be washed clean, effectively solves the difficulty in cleaning off sample residues from the sampling needle and the connection mouth after sampling, and the problem of inaccurate testing results of an instrument due to cross-contamination of samples.</p> |
