Problems solved by technology
[0002] In the prior art, the well-known technology is that biochips are widely used in the fields of new drug development, disease diagnosis and clinical monitoring, and the spotting instrument is used to transfer a small amount of biological samples to the biochip according to a predetermined method to form a microarray. The device, the needle of the spotting instrument needs to be cleaned when it is used. Now most of them directly use the sink to fill the needle with water on one side and the other side to clean it. Due to the slow water flow, the cleaning is not thorough. The needle is generally made of ceramic or glass, which is very easy to scratch. It is not easy to wipe off the needle tip after sampling, which will affect the effect of spotting. This is the deficiency of the existing technology.

The invention provides the technical scheme of a cleaning dip-drying device for a needle head of a sample application instrument. The device provided by the technical scheme comprises a fixed seat. One side of the fixed seat is fixedly provided with a drying box base used for fixing a drying box; the other side of the fixed seat is provided with a cleaning box base used for fixing a cleaning box; the drying box is provided with a plurality of strip-shaped grooves; drying paper covers the top parts of the strip-shaped grooves; the cleaning box is provided with a plurality of cleaning holes; and the bottom part of the cleaning box is provided with an ultrasonic generator. According to the device provided by the technical scheme, the needle head can be thoroughly cleaned, and moreover, dip drying is performed on the needle head, so that the precision of sample application is improved.
Description
technical field [0001] The invention relates to a cleaning, dipping and drying device for the needle of a spotting instrument. Background technique [0002] In the prior art, the well-known technology is that biochips are widely used in the fields of new drug development, disease diagnosis and clinical monitoring, and the spotting instrument is used to transfer a small amount of biological samples to the biochip according to a predetermined method to form a microarray. The device, the needle of the spotting instrument needs to be cleaned when it is used. Now most of them directly use the sink to fill the needle with water on one side and the other side to clean it. Due to the slow water flow, the cleaning is not thorough. The needle is generally made of ceramic or glass, which is very easy to scratch. It is not easy to wipe the needle point after sampling, which will affect the effect of spotting, which is the weak point in the prior art. Contents of the invention [0003...
