As shown in fig. 2 and 3, a virus sampling apparatus according to an embodiment of the present invention includes:

the sampling tube comprises a tube body 110 and a tube cap 120, wherein the tube body 110 is filled with a sample preservation solution;

a sampling swab 200 comprising a swab stem 210 and a sampling head 220, the sampling head 220 being disposed at one end of the swab stem 210;

the unidirectional movable net 300, the unidirectional movable net 300 can be placed in the tube body 110, and can move towards the tube bottom direction of the tube body 110 under the centrifugal action.

As shown in fig. 2 and 3, after the medical staff completes sampling using the sampling swab 200, the sampling tip 220 of the sampling swab 200 is inserted into the tube body 110 and immersed in the sample preservation solution, and then the swab rod 210 is broken or cut off, and then the unidirectional movable net 300 is put into the tube body 110 and the cap 120 is closed.

Because before the internal sampling monitoring of body 110, can carry out the centrifugation step to the sample, at centrifugal process, under the effect of centrifugal force, one-way movable net 300 can move towards the socle direction of body 110, consequently can oppress sampling swab 200 and together move towards the socle direction of body 110, after the centrifugation is ended, sampling swab 200 can stay the bottom at sample preservative solution with one-way movable net 300, can not the come-up to eliminate in follow-up sampling process, the influence of sampling swab 200 to the sample of sampling needle.

In some embodiments of the present invention, the one-way movable net 300 includes a support ring 310 and a net cover 320, the support ring 310 is an elastic ring body, the outer diameter of the support ring 310 matches with the inner diameter of the pipe body 110, the net cover 320 is bowl-shaped, and the net cover 320 is installed on the support ring 310.

As shown in fig. 4 and 5, the one-way movable net 300 is composed of a support ring 310 and a net cover 320, wherein the support ring 310 has a certain elasticity, and in a natural state of the support ring 310, an outer diameter of the support ring 310 is slightly larger than an inner diameter of the pipe body 110, and the support ring 310 can be clamped in the pipe body 110 by the elastic action of the support ring 310, stays in the pipe body 110 without an external force, and moves toward a bottom direction of the pipe body 110 under a centrifugal force. It should be noted that the mesh of the mesh cap 320 is required to ensure proper flow of the specimen preservation solution, while preventing the sampling swab 200 in the specimen preservation solution from passing through the mesh.

In some embodiments of the present invention, the inner wall of the tube body 110 is provided with an annular positioning step 500 near the tube opening, and the support ring 310 can be placed in the ring of the positioning step 500.

As shown in fig. 2 and 3, an annular positioning step 500 is provided on the inner wall of the tube body 110 near the tube opening, so that the support ring 310 can be stably and rightly placed in the tube body 110, and the support ring 310 is prevented from being deviated when the unidirectional movable net 300 is placed in the tube body 110 to affect the movement of the tube body in the subsequent centrifugation process.

The utility model discloses a further embodiment, the step 500 is laid in location includes three hornblocks of a plurality of first right angles, and three hornblock annular of a plurality of first right angles set up, and the inclined plane of three hornblocks of first right angles is radial towards the body, and the inclined plane up.

Specifically, the positioning and placing step 500 is composed of four first right-angle triangular blocks, the four first right-angle triangular blocks are arranged in a ring shape in a surrounding mode, and the support ring 310 is placed on the inclined plane of the first right-angle triangular blocks to complete positioning and placing of the support ring 310. During centrifugation, the support ring 310 slides down along the inclined surface without blocking the movement of the support ring 310.

It should be noted that the first right triangle is not too large, so long as it is used for positioning, and it cannot affect the movement of the support ring 310 too much.

In some embodiments of the present invention, an annular limiting step 600 is disposed on the inner wall of the tube body near the bottom of the tube to limit the supporting ring 310 from reversely walking.

Although the support ring 310 stays in the tube 110 without external force, it does not move. But mainly relies on the elastic action of the support ring 310 itself to achieve the fixing purpose. However, during the transfer process, the movement of the support ring 310 in the tubular body 110 may occur due to the wave motion. Through setting up spacing step 600, spacing step 600 can be crossed to the lock ring 310 in centrifugal action, and after the centrifugation was ended, spacing step 600 can restrict the reverse walking of lock ring 310 to better avoid sampling swab 200 to float.

The utility model discloses a further embodiment, spacing step 600 includes a plurality of second right angle triangle pieces, and a plurality of second right angle triangle piece annular sets up, and the inclined plane of second right angle triangle piece is radial towards the body, and the inclined plane up.

Due to the arrangement of the second right-angle triangular block, the support ring 310 can slide downwards along the inclined surface, and the right-angle side at the lower end of the second right-angle triangular block can achieve the purpose of limiting the support ring 310 to walk reversely.

In some embodiments of the invention, the swab shaft 210 is provided with a neck 211, the neck 211 being located adjacent to the sampling head 220.

By providing a neck section 211, as shown in figure 6, the wiper rod 210 is relatively thin at the neck section 211, so that the wiper rod 210 can be more easily broken off at the neck section 211.

In some embodiments of the present invention, the outer diameter of the sampling head 220 is larger than the outer diameter of the swab rod 210, the bottom of the mesh cap 320 is provided with a through hole 400, and the diameter of the through hole 400 is larger than the outer diameter of the sampling head 220.

As shown in fig. 4 and 5, the one-way movable net 300 can be put into the tube body 110 in advance without being put by medical staff by providing the through hole 400 at the bottom of the net cover 320, thereby improving the collection efficiency. The sampling swab 200 is put in through the through hole 400, and although the aperture of the through hole 400 is larger than the outer diameter of the sampling head 220, the sampling swab 200 can be in a flat lying state under the action of buoyancy after being thrown into the sample preservation solution, and the sampling swab 200 cannot run out of the through hole 400 due to the retained swab rod 210.
