Swab flocking machine for nucleic acid detection sampling

Abstract

The invention relates to a swab flocking machine for nucleic acid detection sampling. The swab flocking machine comprises a box body base, a high-voltage electrostatic flocking box and a clamping and feeding device, the high-voltage electrostatic flocking box and the clamping and feeding device are fixed to the box body base, and a feeding opening is formed in the side face of the high-voltage electrostatic flocking box; the clamping and feeding device comprises a support, a linear feeding mechanism and a rotating mechanism, a fixed part of the linear feeding mechanism is fixed on the support, a fixed part of the rotating mechanism is fixed on a movable part of the linear feeding mechanism, a swab fixing tool is arranged on a rotating part of the rotating mechanism in a manually detachable mode, and the rotating axis of the rotating part of the rotating mechanism is horizontal; the swab fixing tool is used for horizontally fixing a swab; and the swab fixing tool is fed into and moved out of an inner cavity of the high-voltage electrostatic flocking box through the action of the linear feeding mechanism, and the swab fixing tool is rotated through the action of the rotating mechanism. According to the technical scheme, the technical problem that in the prior art, swab fluff is not evenly distributed is solved, automatic feeding into the high-voltage electrostatic flocking box is achieved, and the labor intensity of workers is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of swab flocking machines, in particular to a swab flocking machine for nucleic acid detection and sampling. Background technique [0002] In the field of in vitro diagnostics, swabs are usually used as the main tool for collecting microorganisms, exfoliated cells or secretions. By detecting various components in the swab collection, some diseases can be assisted in the diagnosis. [0003] The new type of coronavirus (2019-nCoV) belongs to the genus β coronavirus, has an envelope, and has round or oval particles with a diameter of 60-140nm. It has 5 essential genes, respectively targeting 4 structural proteins of nucleoprotein (N), viral envelope (E), matrix protein (M) and spike protein (S) and RNA-dependent RNA polymerase (RdRp). The nucleoprotein (N) wraps the RNA genome to form the nucleocapsid, which surrounds the viral envelope (E), and the viral envelope is embedded with proteins such as matrix prote...

AI Technical Summary

Problems solved by technology

[0005] The flocking process of producing flocking swabs is generally to place the swab after gluing horizontally in a high-voltage electrostatic flocking box, and the fluff will stick to the swab during the process of flying up and down. This flocking method makes the swab flocking After velvet, it is easy to have more fluff on the upper and lower sides, less fluff on the left and right sides, uneven distribution of fluff, and unsmooth swab head, resulting in low quality swab products
