Manufacturing method of medical flocking sampling swab

A medical flocking sampling swab, comprising a swab head, a swab rod, and a connection part connecting the swab head and the swab rod, wherein the swab head is an oval ring-shaped stent structure with flocking on the surface; the swab The fiber length of the flocking layer on the surface of the tip holder is 1-1.5mm, the fiber density of the flocking layer is 4-8dtex, and the fiber density of the flocking layer is 25-100μg/mm2; the effective flocking area of the flocking layer of the swab head It is 68-96mm2.

The length of the swab head holder is designed according to ergonomics, and the length of the swab head holder is 12-18 mm.

In order to ensure the strength of the swab head and the swab rod, the connecting part of the utility model includes a cube connecting head and a cylindrical connecting head connected; wherein the cube connecting head is connected with the swab head, and the cylindrical connecting head is connected with The swab rod is connected, and the cross-sectional area of the cylindrical connector is 25-50% of the cross-sectional area of the cube connector.

Further, the cubic connector and the cylindrical connector are integrally formed, and the junction of the cylindrical connector and the cubic connector is located at the center of the side of the cubic connector.

Further preferably, the raw material used for the cylindrical connector is one of unsaturated polyester resin, epoxy resin, silicone resin, and polyurethane resin; the swab head holder, the cube connector and the swab rod are used The raw material is one of polypropylene resin, polyethylene resin, polystyrene resin, polycarbonate resin, acrylic resin, and ABS resin.

Further, the fiber flocked on the surface of the swab head holder is one of viscose fiber and ramie fiber, or a mixed fiber formed by blending one of viscose fiber and ramie fiber with nylon fiber.

Further, the swab head holder, the swab rod, and the connecting part connecting the swab head and the swab rod are integrally formed. The total length of the medical flocking sampling swab is 13-15 cm.
