Description

Technical Field

[0001] The utility model relates to the technical field of blood lipid specimen preparation, in particular to a blood lipid specimen processing device. Background Art

[0002] The preparation of a lipid profile typically involves collecting a blood sample and processing it appropriately for subsequent lipid testing. An appropriate anticoagulant, such as EDTA (ethylenediaminetetraacetic acid), is selected based on the testing requirements. For lipid testing, EDTA is typically used as an anticoagulant to prepare a plasma sample. After collecting the blood, the mixed blood sample is allowed to rest for a period of time to allow the blood components to naturally separate. The blood sample is then centrifuged in a centrifuge. The purpose of centrifugation is to separate the cellular components of the blood, such as red blood cells and white blood cells, from the plasma or serum. After centrifugation, the plasma is aspirated and the separated plasma or serum is transferred to a sterile storage container, labeled with the sample information.

[0003] However, when extracting the separated blood lipids, a sterile pipette or pipette is generally used to extract the upper layer of plasma or serum. This not only places high demands on the operator's proficiency, but also easily absorbs the cellular components of the lower layer during the extraction process, thereby affecting the subsequent blood lipid test results. In this regard, we propose a blood lipid specimen processing device. Utility Model Content

[0016] The utility model has at least the following beneficial effects:

[0017] 1. This blood lipid specimen processing device is provided with a centrifuge tube fixing sleeve. When installing the centrifuge tube, it only needs to be inserted into the inside of the centrifuge tube fixing sleeve. The user rotates the first rotating wheel, and the screw at one end and the fixing mechanism drive the first pressure plate to move toward the wall of the centrifuge tube under the friction of the thread until it is supported and fixed, thereby fixing the device and the centrifuge tube. Subsequently, by turning on the servo motor, the triangular rotor and the roller thereon can be driven to rotate synchronously. When the roller rotates, it will sequentially compress and release the liquid extraction tube to form a peristaltic effect. Under the compression action of the roller, a negative pressure is formed in the liquid extraction tube, and the upper layer of serum in the centrifuge tube is extracted and discharged from the other end of the liquid extraction tube for collection by the user. This device can ensure the stability of the upper layer serum extraction process and effectively improves the convenience.

By removing the fastening screws, the detachable side cover can be separated from the blood lipid extraction mechanism. At this time, the used liquid extraction tube can be taken out. When replacing the new liquid extraction tube, the middle part of the liquid extraction tube is preferably engaged between the roller and the inner wall of the blood lipid extraction mechanism, and then the two ends are passed through the first tube opening and the second tube opening respectively, and finally the detachable side cover is closed and reinforced with the fastening screws. After the centrifuge tube is fixed in the centrifuge tube fixing sleeve, the servo motor is started or the liquid extraction tube is manually pulled to adjust the lifting and lowering of one end of the liquid extraction tube inside the centrifuge tube, so that one end of the liquid extraction tube is located in the upper layer of serum. After the adjustment is completed, the second rotating wheel is rotated, and the second pressure plate is clamped on the outer wall of the liquid extraction tube due to the friction between it and the thread of the tube opening, thereby ensuring the firmness of the liquid extraction tube in this position, on the one hand, preventing the suction end from moving in the centrifuge tube, and on the other hand providing the prerequisite for the peristaltic effect generated by the roller squeezing the liquid extraction tube.

[0019] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the above scheme, by turning on the servo motor, the triangular rotor and the roller on it can be driven to rotate synchronously.
