Embodiment Construction

[0056]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly...

Abstract

The invention discloses a blood sample treatment method. The blood sample treatment method comprises the following steps: providing a blood sample separation carrier provided with a sample adding cavity, a separation cavity, a sample adding position and a sampling position; a blood sample is added into the sample adding cavity through the sample adding position, the blood sample separation carrier is controlled to rotate at a preset rotating speed in an accelerated mode, and the blood sample in the sample adding cavity enters the separation cavity; the blood sample separation carrier is controlled to rotate at a constant speed at a preset rotating speed for a first preset time, so that a first component and a second component in the blood sample are separated, and the first component and the second component obtained through separation are contained in the separation cavity; controlling the blood sample separation carrier to decelerate and rotate for a second preset time until the blood sample separation carrier stops rotating, so that the first component in the separation cavity is collected in the space, close to the sampling position, of the separation cavity; and the first component separated in the separation cavity is extracted through the sampling position. The blood sample treatment method provided by the invention can reduce the detection dosage and sampling precision requirements of the blood sample.

Description

technical field [0001] The invention relates to the technical field of blood sample detection, in particular to a blood sample processing method. Background technique [0002] Blood is one of the most commonly used samples in clinical tests. Various physiological and pathological information of subjects can be obtained from blood through various detection methods such as biochemistry and immunity, providing a basis for clinical diagnosis and treatment. At present, most of the blood tests need to separate blood components in the blood sample preprocessing stage, and then perform subsequent detection on the separated blood components separately. [0003] In the related art, blood samples are collected through a blood collection tube, and the blood collection tube is placed in a centrifuge for centrifugal separation. When extracting the separated blood sample, in order to ensure the sampling purity, it is necessary to determine the position and location of the suction tube exte...
