Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube technology, specifically a medical bullet-shaped centrifuge tube holder. Background Technology

[0002] Medical bullet centrifuge tubes are widely used in medical and biological experiments. The tube body is shaped like a bullet with a pointed cone bottom. This design helps to concentrate and precipitate solids in the liquid to the pointed tip of the tube during centrifugation, making it easier to collect and separate the precipitate and improving experimental efficiency and accuracy. Medical bullet centrifuge tube racks are devices used to store and secure medical bullet centrifuge tubes.

[0003] The placement slots on existing medical bullet centrifuge tube holders are mostly of a general design, which cannot stably hold conical centrifuge tubes. As a result, the conical centrifuge tubes on the holder are easily spilled out of the slots due to external contact, which affects the practicality of the holder. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A medical bullet-shaped centrifuge tube holder includes a holder body and conical centrifuge tubes. The holder body is provided with multiple sets of placement slots, and the conical centrifuge tubes can be placed in the placement slots. The bottom end of the placement slot is a conical groove that can fit with the conical end of the conical centrifuge tube.

[0007] Preferably, a first magnet is provided at the conical bottom of the conical centrifuge tube, and a second magnet that can be attracted to the first magnet is provided in the conical groove.

[0024] Please see Figures 1-4 A medical bullet-shaped centrifuge tube holder includes a holder body 1 and conical centrifuge tubes 3. The holder body 1 has multiple placement slots 2, into which the conical centrifuge tubes 3 can be placed. The bottom end of each placement slot 2 is a conical groove 4 that fits into the conical end of the centrifuge tube 3. The holder body 1 serves as the basic frame for the entire device, supporting all components and providing a stable platform for the conical centrifuge tubes 3. Made of acid- and alkali-resistant plastic, it is not easily corroded in environments involving chemical reagents and disinfectants, extending its service life and adapting to the complex chemical environments of laboratories. The placement slots 2 are groove structures for directly placing the conical centrifuge tubes 3. By limiting the position of centrifuge tubes with preset sizes and shapes, the centrifuge tubes are prevented from tipping over or shaking, ensuring their stability during storage and transfer, and avoiding sample leakage or contamination. The conical centrifuge tube 3 is the core component for storing samples. Its conical structure adapts to the conical groove 4 of the placement groove 2, achieving stable placement. At the same time, its conical end design facilitates the collection of sample precipitates after centrifugation. The shape of the conical groove 4 is completely fitted with the conical end of the conical centrifuge tube 3. Through the matching of physical structures, the bottom of the centrifuge tube is in close contact with the placement groove 2, preventing the centrifuge tube from shifting its center of gravity due to tilting during placement, while reducing wear on the bottom of the centrifuge tube and protecting the conical end of the centrifuge tube.

[0025] Please see Figure 2A first magnet 5 is provided at the conical bottom of the conical centrifuge tube 3, and a second magnet 6 is provided in the conical groove 4 that can attract the first magnet 5. The first magnet 5 and the second magnet 6 in the conical groove 4 attract each other, and the centrifuge tube is further fixed by magnetic force to prevent the centrifuge tube from falling out of the placement groove 2 when the rack is moved or subjected to slight external force (such as collision or vibration). It is especially suitable for scenarios where centrifuge tubes need to be moved frequently, and enhances the overall stability. The second magnet 6 is a cooperating part for magnetic attraction, and forms an attraction with the first magnet 5. The connection between the centrifuge tube and the placement groove 2 is reinforced by magnetic force, which makes up for the lack of physical structure fixation and ensures that the centrifuge tube is not easy to loosen even if it is subjected to external force during placement.

[0026] Please see Figure 3 and Figure 4 The main body 1 of the storage rack is equipped with a splicing structure that can be assembled together. The splicing structure consists of a splicing groove 7 and a splicing block 8 that can cooperate with the splicing groove 7. The splicing groove 7 and the splicing block 8 are respectively arranged opposite each other on both sides of the main body 1 of the storage rack. A magnet 9 is installed inside the splicing groove 7, and a magnet 10 that can cooperate with the magnet 9 is installed on the splicing block 8. The splicing groove 7 and the splicing block 8 work together to realize the splicing combination of multiple storage racks 1. The splicing block 8 is inserted into the splicing groove 7, and the adjacent storage racks are connected into a whole through the interlocking of the physical structure. This makes it easy to flexibly expand the placement capacity according to the number of centrifuge tubes (such as multiple storage racks spliced ​​side by side), improve space utilization and ease of operation. The attraction between the magnets 9 and 10 further enhances the splicing firmness and prevents the storage racks from separating due to vibration during movement or use after assembly, ensuring the overall stability of the assembly.

[0027] Please see Figure 4 The main body 1 of the storage rack is equipped with an L-shaped support leg 11. The bottom of the L-shaped support leg 11 is equipped with an anti-slip pad 12. The L-shaped support leg 11 supports the main body 1 of the storage rack, keeping the main body at a certain distance from the table surface, preventing water stains and dirt from the table surface from directly contacting the bottom of the storage rack. At the same time, the "L-shaped" structure disperses the weight, enhancing the overall load-bearing capacity and stability of the storage rack and preventing it from tipping over. The anti-slip pad 12 increases the friction between the support leg and the table surface (such as a laboratory table), preventing the storage rack from sliding due to slight movement (such as collision or dragging) during placement or use, further improving the overall stability and preventing centrifuge tubes from tipping over or falling due to sliding.

[0028] Please see Figure 1The main body of the holding rack 1 is made of plastic material resistant to strong acids and alkalis. The plastic material resistant to strong acids and alkalis is polytetrafluoroethylene (PTFE / Teflon), fluorinated ethylene propylene copolymer (FEP), soluble polytetrafluoroethylene (PFA) and other plastic materials. It can resist the corrosion of chemical reagents such as strong acids, strong alkalis and organic solvents commonly used in laboratories, ensuring that the holding rack will not deform or be damaged after long-term contact with chemical environment. At the same time, it avoids the release of impurities after the material is corroded, which will contaminate the centrifuge tubes or samples, thus ensuring the safety and accuracy of the experiment.

[0029] Working principle: The main body 1 of the holding rack serves as the basic frame, and the placement slot 2 on it provides space for the conical centrifuge tubes 3. The conical groove 4 at the bottom of the placement slot 2 completely fits the conical end of the centrifuge tube, forming an initial fixation through shape matching. The physical structure restricts the tilting and swaying of the centrifuge tubes, ensuring that the bottom of the centrifuge tubes is in close contact with the placement slot 2 and maintaining a stable center of gravity. The first magnet 5 at the conical bottom of the conical centrifuge tube 3 attracts the second magnet 6 inside the conical groove 4, adding magnetic constraint on the basis of physical fixation, further enhancing the connection strength between the centrifuge tubes and the placement slot 2. Even if subjected to external forces such as touch or vibration, the magnetic force can offset part of the impact. Force is applied to prevent centrifuge tubes from falling off; the splicing grooves 7 and splicing blocks 8 on both sides of the main body 1 of the rack are physically fitted together to achieve splicing of multiple racks. At the same time, the magnet 9 in the splicing groove 7 and the magnet 10 on the splicing block 8 attract each other, strengthening the overall firmness after splicing, so that multiple racks form a stable whole to meet the placement needs of different numbers of centrifuge tubes; the L-shaped support legs 11 provide stable support for the main body 1 of the rack, separating the main body from the table surface to avoid the influence of table surface stains. The anti-slip pads 12 at the bottom increase the friction with the table surface to prevent the rack from sliding as a whole, ensuring the stability of the device from the bottom and indirectly reducing the risk of centrifuge tubes tipping over due to the movement of the rack.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
