[0025] This integrated centrifuge tube for drug preparation and sieving includes an outer tube 1, a grinding inner tube 2, a limiting ring 3, and a sealing cap 5 (see instruction manual appendix). Figure 1 and 2 ).

[0026] The upper end of the outer tube 1 is provided with an internal thread A6 (see the instruction manual appendix). Figure 2 and 9 The bottom end of the outer tube 1 is provided with an arc-shaped inner grinding surface 7 (see the instruction manual appendix). Figure 8 ).

[0027] The outer tube 1 is internally threaded and connected to a ground inner tube 2 (see instruction manual appendix). Figure 2 and 4 The lower end of the grinding inner tube 2 is provided with an arc-shaped outer grinding surface 8 (see the instruction manual appendix). Figure 7 The purpose of setting the grinding inner tube 2 in this way is to allow the pills to be prepared to be placed inside the preparation outer tube 1 during operation; then, after the grinding inner tube 2 is fitted inside the preparation outer tube 1, the grinding inner tube 2 is tightened so that the pills are crushed and ground into powder by the action of the arc-shaped outer grinding surface 8 and the arc-shaped inner grinding surface 7.

[0028] The upper part of the grinding inner tube 2 is provided with a knob ring 9; the wall of the grinding inner tube 2 below the knob ring 9 is provided with an external thread A10; the grinding inner tube 2 is connected to the outer tube 1 through the external thread A10 and the internal thread A6; the wall of the grinding inner tube 2 above the knob ring 9 is provided with an external thread B11 (see the instruction manual). Figure 6 During operation, the grinding inner tube 2 can be installed by rotating the ring 9 knob.

[0029] A stepped countersink 12 is provided at the top edge of the grinding inner tube 2 (see the instruction manual appendix). Figure 2 The stepped settling tank 12 has an internal thread C (not shown in the attached diagram of the instruction manual). The top of the grinding inner tube 2 is fitted with filter paper 4 via a limiting ring 3 (see attached diagram of the instruction manual). Figure 2 , 4 and 5).

[0030] The outer surface of the limiting ring 3 is provided with an external thread C13; the upper end of the grinding inner tube 2 is fitted with the limiting ring 3 through the internal thread C and the external thread C13; a filter paper 4 is clamped between the limiting ring 3 and the grinding inner tube 2 (see the instruction manual appendix). Figure 4 and 5 The purpose of this arrangement is to ensure that the filter paper 4 is fixedly mounted on the upper end face of the grinding inner tube 2 by means of the limiting ring 3, so as to avoid the problem of the filter paper 4 detaching from the grinding inner tube 2.

[0031] A sealing cap 5 is threadedly connected to the upper end of the grinding inner tube 2. The sealing cap 5 has an internal thread B16; the sealing cap 5 is connected to the grinding inner tube 2 via the internal thread B16 and the external thread B11 (see the appendix to the instruction manual). Figure 1 and 2 The upper end of the limiting ring 3 is provided with a locking pin 15 (see the instruction manual appendix). Figure 10 The upper end of the sealing cap 5 is provided with a snap-fit ​​hole 14 (see the instruction manual). Figure 10 The locking hole 14 of the sealing cover 5 is intermittently locked to the locking pin 15.

[0032] The purpose of setting the sealing cover 5 and the limiting ring 3 in this way is to allow the sealing cover 5 to be flipped so that the snap hole 14 and the snap pin 15 can be snapped together when the limiting ring 3 is assembled or disassembled. Then, when the sealing cover 5 is twisted, the sealing cover 5 can drive the limiting ring 3 to rotate synchronously through the snap hole 14 and the snap pin 15, thus achieving the purpose of facilitating the assembly or disassembly of the limiting ring 3.

[0033] When this integrated centrifuge tube for dispensing and sieving is in operation, the pills to be dispensed are first placed inside the outer tube 1; then the inner grinding tube 2 is fitted inside the outer tube 1 and tightened so that the pills are crushed and ground into powder by the action of the arc-shaped outer grinding surface 8 and the arc-shaped inner grinding surface 7.

[0034] After the powder is ground into shape, the inner grinding tube 2 is removed from the outer preparation tube 1. Then, the liquid medicine is put into the outer preparation tube 1 as required to mix it thoroughly with the powder medicine to prepare a solution.

[0035] After the working solution is prepared, remove the sealing cap 5, then flip the inner grinding tube 2 so that its upper end is threadedly connected to the outer configuration tube 1; then rotate it so that the inner grinding tube 2 is below the outer configuration tube 1 (see the instruction manual appendix). Figure 8 At this point, the solution in the outer tube 1 will pass through the filter paper 4 under gravity and enter the inner grinding tube 2 to form the working solution. After filtration, the outer tube 1 is removed, and the inner grinding tube 2 and the working solution are centrifuged. After the work is completed, the integrated centrifuge tube for drug preparation and sieving is cleaned and a new filter paper 4 is replaced. The centrifuge tube is then ready for the next working cycle.

[0036] This integrated centrifuge tube for drug preparation and sieving is compact and ingeniously designed. It can complete the grinding of drugs, preparation of drug solutions and filtration, thus solving the problem of complicated operation procedures caused by the lack of drug solution preparation function in existing centrifuge tubes. It is particularly suitable for the needs of biological and medical testing.
