This utility model relates to the field of bilirubin concentration detection technology, and mainly to an extraction device for bilirubin concentration detection. It includes an aspirator tube for serum aspiration, a storage frame, and an operating tube. Multiple aspirator tubes are inserted into the storage frame. The operating tube has a connector, and the connector and the storage frame have a docking part. The storage frame has a pushing part for moving multiple aspirator tubes into the operating tube, and a pushing component is located inside the operating tube. This utility model optimizes the traditional serum collection method for bilirubin concentration detection. By using a designed negative pressure adsorption component in conjunction with the aspirator tube, it achieves the absorption and storage of the upper serum layer. Compared with the traditional method of immediate transfer after aspirating with a pipette, personnel can extract all the serum in batches at once. During operation, it effectively avoids forgetting to replace the pipette or serum contamination caused by contact between the pipette and the outside environment.
