An automatic processing device for liquid samples includes a sample region, a control module, an image identification device and a centrifuge. The sample region is configured to accommodate a plurality of centrifuge tubes. The control module includes a mechanical module. The mechanical module is configured to unscrew or tighten upper caps of the centrifuge tubes, and is configured to draw liquid from the centrifuge tubes or discharge liquid to the centrifuge tubes. The image identification device is coupled to the control module. The centrifuge is coupled to the control module. The centrifuge is configured to accommodate the centrifuge tubes and perform centrifugal treatment.

A centrifugal separation device including a supporter attached to a centrifuge and a divisional part removable from the supporter is provided. The divisional part has two flow channels and an extracting part. The flow channels extend substantially in parallel to the direction in which centrifugal force acts, and are connected to each other on the leading end side in the direction in which centrifugal force acts. One of the flow channels is a sample flow channel having a sample inlet on the base end side in the direction in which centrifugal force acts, and the other flow channel is an air-discharging flow channel having an outlet on the base end side. The extracting part includes part of the sample flow channel, and has a connecting part for the part to be cut off from the remainder of the sample flow channel.

A molecular diagnostic device and a detection card conveying seat for the same. The detection card conveying seat includes: a pressure plate, arranged with a first slide rail component, where the pressure plate is slidable along a sliding direction of the first slide rail component; and a transporting assembly, configured to place a detection card. The transporting assembly includes: a sliding frame, where the sliding frame is slidable together with the pressure plate along the sliding direction under an action of an abutting force; and a card tray, connected to the sliding frame and configured to place the detection card, where the pressure plate is configured to move toward the detection card and movable to a position abutting against the detection card, in condition of the sliding frame being subjected to a force that overcomes the abutting force.

A system and apparatuses or devices capable of automatically performing processes of cell treatment preparatory to flow cytometry and similar cytological studies in a fully automated and streamlined manner are provided. The system and apparatuses or devices are adapted for preparation and (pre)processing of cell samples, e.g., blood and/or bone marrow samples.

The present disclosure relates to blood sample preparation devices and methods. In some embodiments, a method for preparing a blood sample comprises: receiving at a sample preparation machine a sample container containing the blood sample; scanning an identifier of the sample container, the identifier containing information indicative of a characteristic of at least one of the sample container or the blood sample contained therein, actuating, after the scanning, and based on the information, the sample container to repeatedly change a position of the sample container; determining, based on the information, whether the sample container should be centrifuged; and transporting the sample container to a centrifuge to be centrifuged and then to a storage compartment when the determining indicates that the sample container should be centrifuged, and to the storage compartment without entering the centrifuge when the determining indicates that the sample container should not be centrifuged.
