Detailed Description

The present disclosure is described in further detail below with reference to the figures and the specific embodiments. Advantages and features of the present invention will become apparent from the following detailed description and claims. It is noted that the drawings are in greatly simplified form and that non-precision ratios are used for convenience and clarity only to aid in the description of the embodiments of the utility model.

It will be appreciated that in existing tubes, liquid remains in the tube after use, and that the solid surface of the tube remains wet after the liquid is poured from the tube. Therefore, the centrifugal tube with better solid-liquid separation effect needs to be provided. Fig. 1 shows a schematic structural diagram of a centrifugal sleeve in an embodiment of the present disclosure (after assembly), and fig. 2 shows a schematic structural diagram of a centrifugal sleeve in an embodiment of the present disclosure (before assembly). As shown in fig. 1 and 2, the centrifugal casing includes an outer tube 1 and an inner tube 2, as shown in fig. 3, the outer tube 1 is provided with a first cavity 11, the first cavity 11 is provided with a first opening 12, and the inner tube 2 can be installed in the first cavity 11 through the first opening 12; as shown in fig. 4, the inner tube 2 is provided with a second cavity 21, a second opening 22 is provided at the top of the second cavity 21, a filtering hole 23 is provided at the bottom of the second cavity 21, the inner tube 2 is further provided with a first sealing cover 24, the first sealing cover 24 is detachably mounted at the second opening 22, and when the first sealing cover 24 is mounted at the second opening 22, the first sealing cover 24 seals the second opening 22. According to the scheme, the outer pipe 1 and the inner pipe 2 are arranged, and the filter holes 23 are formed in the inner pipe 2, so that when the centrifugal sleeve is used for centrifugation, liquid in the inner pipe 2 reaches the outer pipe 1 through the filter holes 23 under centrifugal acting force, and therefore the state that solid in the inner pipe 2 is separated from liquid in the inner pipe 2 is achieved. Compared with the prior art, the scheme can further improve the effect of separating the solid from the liquid, and the centrifuged solid is drier.

In order to improve the solid-liquid separation effect, in some embodiments, the bottom of the first cavity 11 is provided with a filter layer. The water is further separated by the filter layer, so that less liquid is in the inner tube 2.

In some embodiments, protrusions 112 are provided on the bottom of first cavity 11, since the centrifuged endodontic polymer may stick to the inner wall of first cavity 11, making it difficult for a medical practitioner to remove it with forceps. So that the health care professional can pick up the endodontic polymer by grasping the edge of the endodontic polymer that is pushed up by protrusion 112 with forceps.

In some embodiments, as shown in fig. 1 and fig. 2, the outer tube 1 is not provided with a sealing cover, and the outer tube 1 and the inner tube 2 are fixed by their own fixing structure, but because there is no matched centrifuge, the centrifuge sleeve put into the centrifuge is not necessarily matched with the cavity of the centrifuge, some gaps still remain, the cover of the centrifuge is not necessarily pressed against the centrifuge sleeve, so that the centrifuge sleeve may vibrate up and down during centrifugation, and the inner tube 2 is separated from the outer tube 1, thereby causing accidents. Therefore, in some embodiments, as shown in fig. 6, the outer tube 1 is provided with a second sealing cap 13, the second sealing cap 13 being used to seal the first opening 12. By providing the outer tube 1 with a second sealing cap 13 it is ensured that the liquid in the outer tube 1 does not spray out.

Since the first sealing cap 24 is disposed at one end of the inner tube 2 through a flexible connection member if the inner tube 2 is the same as some existing centrifuge tubes, the inner tube 2 occupies a large space when it is placed in the first receiving cavity 11, which is not favorable for placing the inner tube 2 in the first receiving cavity 11, and therefore, in some embodiments, the second sealing cap 13 is connected to the first sealing cap 24. Thereby connect fixed first sealed lid 24 through second sealed lid 13 for under normal conditions, second sealed lid 13 can be dismantled with first sealed lid 24 and be connected, does not need inner tube 2 to set up flexible connectors specially and fixes first sealed lid 24, has reduced the complexity of first appearance chamber 11.

In some embodiments, the first seal cap 24 is removably coupled to the second seal cap 13. Specifically, as shown in fig. 6, the first sealing cover 24 is provided with an upper protruding edge 241, and the first sealing cover 24 is detachably coupled to the second sealing cover 13 by the upper protruding edge 241. The first sealing cover 24 is detachably connected with the second sealing cover 13, so that a user can more conveniently remove the first sealing cover 24 from the second sealing cover 13 and install the first sealing cover 24 in the first opening 12.

Of course, in some embodiments, the first sealing cover 24 and the second sealing cover 13 are connected to each other, and when the first sealing cover 24 is installed in the second opening 22, the second sealing cover 13 may also be installed in the first opening 12. So that the first sealing cover 24 and the second sealing cover 13 do not necessarily need to be detachably connected, the first sealing cover 24 and the second sealing cover 13 can be used for sealing the second opening 22 and the first opening 12 respectively. More specifically, the second sealing cover 13 is provided with a first protruding rim 131, and the second sealing cover 13 is engaged with the first opening 12 through an outer wall of the first protruding rim 131, so that the second sealing cover 13 is detachably mounted on the first opening 12. Meanwhile, the inner wall of the first flange 131 is connected to the top (or the upper flange 241) of the first sealing cover 24, and the bottom of the first sealing cover 24 is provided with a lower flange 242, and the first sealing cover 24 is detachably mounted on the second opening 22 through the lower flange 242.

The inner tube 2 is fixed in the first receiving cavity 11, for example, in some embodiments, as shown in fig. 3, an inner wall of the first receiving cavity 11 is provided with a rubber ring 111, and when the inner tube 2 is installed in the first receiving cavity 11, an outer wall of the inner tube 2 abuts against the rubber ring 111 to fix the inner tube 2 in the first receiving cavity 11.

In some embodiments, the inner wall of the first receiving chamber 11 is provided with a first fixing protrusion, the outer wall of the inner tube 2 is provided with a second fixing protrusion, and the inner tube 2 is placed in the first receiving chamber 11 by the first fixing protrusion and the second fixing protrusion.

Additionally, in some embodiments, when the inner tube 2 is installed in the first receiving cavity 11, the outer wall of the inner tube 2 abuts against the inner wall of the first receiving cavity 11 to fix the inner tube 2 in the first receiving cavity 11. More specifically, first appearance chamber 11 is equipped with first fixed section, and the open area that holds chamber 11 at the first of first fixed section down diminishes from last gradually, and inner tube 2 is equipped with the second fixed section, and the outer wall of inner tube 2 matches with the open shape that holds chamber 11 at the first of first fixed section in the second fixed section in order to be fixed in outer tube 1 with inner tube 2.
