Abstract

The invention relates to a sample adding needle and plate cleaning head integrated needle cleaning module. Step through holes (1,8) are distributed at the left side and the right side of the module; a plate cleaning head needle cleaning groove (2) is distributed at the back side of the upper part of the module, and a sample adding needle cleaning groove (10) is distributed at the front side of the upper part of the module; a partition rib (7) is arranged between the plate cleaning head needle cleaning groove (2) and the sample adding needle cleaning groove (10); magnetic rod accommodating blind holes (3,4,5,6) which are distributed at equal distance are distributed on the surface of a template; a sample adding needle inner wall cleaning hole (9) is distributed at the right side of the sample adding needle cleaning groove (10); a sample adding needle outer wall cleaning hole (11) is distributed in the middle of the sample adding needle cleaning groove (10); the middle of the plate cleaning head needle cleaning groove (2) is provided with a magnetic rod accommodating rib (12); the upper surface of the magnetic rod accommodating rib (12) is parallel and level to the upper surface of the sample adding needle and plate cleaning head integrated needle cleaning module; the magnetic rod accommodating blind holes (3,4,5,6) are arranged in the magnetic rod accommodating rib (12); and the upper surface of the partition rib (7) is slightly lower than that of the sample adding needle and plate cleaning head integrated needle cleaning module. The invention has the advantages of thoroughcleaning, difficult cross contamination and high efficiency.

Description

technical field [0001] The invention relates to a sample loading device, in particular to an integrated needle washing module for a sample loading needle and a plate head. Background technique [0002] The sampling needle can be used in automatic enzyme immunoassay workstations, automatic sampling systems, etc. The use of sampling needles is mainly used for the distribution and transfer of liquids. It has a wide range of applications, including clinical testing, pharmaceuticals, life science research, animal and plant inspection and quarantine research, etc. It is often used in clinical serological enzyme plate tests and blood group tests. Sample addition work, such as blood stations, etc. Laboratory work functions such as sample addition, dilution, reagent addition, mixing, specimen collection, and sample retention from the original test tube to the 96-well ELISA plate and blood type plate through the injection needle, as well as the pooling and mixing of DNA and NAT exper...
