Description

Technical Field

[0001] The utility model relates to the technical field of research and development of centrifuge hanging basket adapters, in particular to a centrifuge peripheral blood hanging basket adapter. Background Art

[0002] Peripheral blood centrifugation is a commonly used examination method in clinical medicine. It uses a centrifuge to centrifuge samples collected from human peripheral blood to separate different components for detection and analysis. This examination method can provide doctors with a lot of important information because it can analyze the number, morphology and functional characteristics of different cells in the blood, as well as various disease-related biomarkers, such as proteins, enzymes and hormones.

[0003] According to the applicant's search, most micro-peripheral blood centrifuges are filled with EP centrifuge tubes. This type of centrifuge tube is used in conjunction with a micro centrifuge for separation and centrifugation of trace reagents, and the test tube needs to be placed in an appropriate hanging basket. The centrifuge tube hanging basket adapter is a device used in a centrifuge to cooperate with the hanging basket (rotor) and centrifuge tube. Its main function is to ensure that the centrifuge tube can be stably and safely fixed on the hanging basket during the centrifugation process to prevent the centrifuge tube from shifting or falling off during high-speed rotation.

[0004] Since the existing hanging basket adapter consists of a base and a support plate for placing test tubes, and the support plate is provided with two or three placement slots, during testing, multiple test tubes are mostly placed in a large groove for centrifugal testing. In this way, multiple test tubes are squeezed together, which is prone to collision, and the limiting effect is poor, and the space utilization rate is not high, resulting in the need for multiple tests during centrifugal operation, which is inefficient. At the same time, the integrated design of the support plate and the base is also inconvenient to carry and maintain. Once damage somewhere affects the use, the entire unit needs to be replaced.

[0005] Therefore, in view of the above problems, it is necessary for the applicant to design a centrifuge peripheral blood basket adapter to solve the problem. Utility Model Content

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] like Figure 1-Figure 5 As shown, a peripheral blood hanging basket adapter for a centrifuge of the utility model comprises a base 1 and a tray 2, the base 1 is provided with two slots 11, a bevel plug-in block 4 is engaged in the slot 11, a tray 2 is mounted on the top of the bevel plug-in block 4, the tray 2 comprises a plurality of right-angle blocks 22 and rounded blocks 21 spliced ​​to each other, the rounded blocks 21 are located at the edge positions on both sides, and the right-angle block 22 is located in the middle position, one side of the right-angle block 22 is evenly provided with four insertion holes and the other side is provided with four corresponding protrusions 23, one side of the rounded block 21 at one end is provided with four protrusions 23, and one side of the rounded block 21 at the other end is provided with four insertion holes, the protrusions 23 are inserted into the insertion holes and fixed with screws A24, the screws A24 are inserted from the top of the right-angle block 22 and the rounded block 21, the top surfaces of the right-angle block 22 and the rounded block 21 are provided with a row of tube grooves 5, EP test tubes 3 are placed in the tube grooves 5 and fit each other, and the bevel plug-in block 4 is installed at the bottom of the rounded block 21.

[0024] Through the above structural design, when conducting experiments, the base 1 is fixed in the hanging basket of the centrifugal device, and the right-angle block 22 and the rounded block 21 are spliced ​​with each other. When splicing, the protrusion 23 is inserted into the groove of the adjacent right-angle block 22 or the rounded block 21, and the protrusion 23 located at the top has a screw hole. Then, the screw A24 is inserted from the top of the right-angle block 22 or the rounded block 21 into the groove and docked with the protrusion 23, and then the inclined surface plug block 4 is docked with the bottom of the rounded block 21, and then the inclined surface plug block 4 is inserted into the two card slots 11 on the base 1 to complete the assembly. When working, all EP test tubes 3 with a capacity of 1.5 ml are placed in the tube slot 5, and the centrifuge can be started to perform centrifugal work.

[0025] The inclined surface of the inclined surface plug block 4 fits with the inclined surface of the card slot 11, and the other vertical surface of the inclined surface plug block 4 fits with the rubber pad 12 on the vertical surface inside the card slot 11. The inclined surface of the inclined surface plug block 4 is also fixed with two clamping blocks 41, which are clamped into the grooves of the inclined surface of the card slot 11.

[0026] By designing the rubber pad 12 and the clamping block 41, when the inclined surface block 4 is inserted into the slot 11, the clamping block 41 is inserted into the groove of the inclined surface of the slot 11.
