Abstract

The invention discloses a magnetic separation cleaning needle structure. The magnetic separation cleaning needle structure comprises a needle module, and a top plate and a mounting plate arranged up and down; the needle module includes a needle sleeve, and at least one needle fixed in the needle sleeve; the needle sleeve is coated with a spring; the top plate is provided with a first guide hole; the mounting plate is provided with a second guide hole; the needle module is inserted in the top plate and the mounting plate through the first guide hole and the second guide hole; the spring is positioned between the top plate and the mounting plate; and the top plate and the mounting plate are connected through a stand column. The cleaning needle structure effectively solves the problems of difficult pipe insertion and inflexible elastic mechanism, and is simple in structure and convenient for installation.

Description

technical field [0001] The invention relates to a magnetic separation cleaning needle structure, which belongs to the field of cleaning equipment in medical instruments. Background technique [0002] Chemiluminescent equipment needs to repeatedly absorb waste liquid and inject liquid for cleaning in the magnetic separation stage of cleaning. In order to realize the above functions, generally two needles need to be included. One is a liquid suction needle, which is used to absorb the waste liquid in the cuvette; the other is a liquid injection needle, which is used to inject cleaning solution into the cuvette. At present, the elastic mechanism of cleaning needles on most equipment is inflexible, prone to failure, and cannot guarantee effective residual volume. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a magnetic separation cleaning needle structure in which the cle...
