Detailed Description
In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1-3, an embodiment of the present invention has a structure: a mucosa negative pressure virus sampling device comprises a cotton swab with a negative pressure device and a preservation liquid bottle 5 with a cotton swab head removing device. Negative pressure is generated through the negative pressure device, so that the swab head at the front end of the cotton swab can absorb more sample liquid, and the sample liquid can fully enter the sampling head.
In a preferred embodiment, as shown in fig. 2, the cotton swab with the negative pressure device comprises a rod body 2 with a hollow tubular structure, a cavity 1 at the tail end of the rod body 2 and a sampling head 4 at the front end of the rod body 2. The vacuole 1 and the rod body 2 can be of an integrated structure, and can also adopt a detachable installation structure; the cavity 1 and the shaft body 2 may all be of a transparent plastics material.
In a preferred embodiment, the material of the sampling head 4 is a fibrous material. The fiber material is arranged at the front end of the rod body 2 in a winding mode.
In a preferred embodiment, the fibrous material is medical cotton.
In a preferred embodiment, in order to improve the sucking uniformity and the collecting efficiency of the sampling head 4, the front end of the rod body 2 is provided with a plurality of fine holes on the outer wall for winding the sampling head 4.
In a preferred embodiment, as shown in fig. 2-3, the swab head removing device is a pull-off rack 6 arranged on the inner wall of the preservation solution bottle 5. The pulling-off frame 6 is fixedly arranged on the mounting seat 7, then the mounting seat 7 is arranged on the inner side wall of the preservation liquid bottle 5, and the mounting seat 7 can be fixedly arranged on the inner side wall of the preservation liquid bottle 5 or can be arranged on the inner side wall by adopting a detachable structure.
