Embodiment Construction

[0029] figure 1 It is a diagram showing the overall structure of a preferred sample processing device ("this sample processing device") for carrying out the present invention. The sample processing device has a distribution processing function, which includes sucking the blood sample placed in the blood collection tube T and discharging the blood sample into the sub-sample container. In the processing stage upstream of the sample processing device, for example, the blood sample in the blood collection tube T is subjected to centrifugal treatment by a centrifugal device, so that the blood sample is separated into blood coagulation factors, a separating agent and serum in the blood collection tube T, and from The bottom is positioned in that order. Serum is removed from the centrifuged blood collection tube T by the distribution processing function of the sample processing device. The serum remaining in the blood collection tube T and the serum removed from the blood collectio...

Abstract

A sample processing device is provided, comprising: a distribution unit (10), which sucks and discharges a blood sample through a nozzle (12); a liquid level measurement unit (20), which measures the level of the blood sample contained in a blood collection tube (T); liquid level height (Hd); serum amount estimation unit (30), which estimates the amount of serum separated in the blood sample based on the total amount of blood (Vd) and the hematocrit value, said total amount of blood corresponding to the amount of the blood sample, And has been deduced from the liquid level height (Hd) measured above; the remaining amount estimation unit (40), which is based on the serum amount estimated by the serum amount estimation unit (30) and the amount of serum to be sucked by the dispensing unit (10) to calculate the amount of remaining serum after suction; and a controller (100) that controls the suction process of the dispensing unit (10) so that the estimated remaining amount not less than the desired serum amount remains in the blood collection tube (T).

Description

technical field [0001] The invention relates to a sample processing device for processing blood samples. Background technique [0002] When the blood collection tube containing the blood sample and the separation agent is centrifuged, the blood sample is separated in the blood collection tube into serum and coagulation factors respectively located on both sides of the separation agent. For example, applying a centrifugal force toward the bottom of the blood collection tube causes the blood coagulation factors, separation agent, and serum in the blood collection tube to separate and appear in this order from the bottom. Subsequently, the serum is removed from the centrifuged blood collection tube using a dispensing device or the like, and the serum remaining in the blood collection tube and the serum removed from the blood collection tube are examined and analyzed. [0003] In order to test and analyze the serum remaining in the blood collection tube, the amount of serum req...
