Manufacturing method of medical flocking sampling swab
A medical flocking sampling swab, comprising a swab head, a swab stick, and a connecting part connecting the swab head and the swab stick, wherein the swab head has an oval ring-shaped support structure with flocking on the surface; the surface of the swab tip support The fiber length of the flocking layer is 1-1.5mm, the fiber density of the flocking layer is 4-8dtex, the fiber density of the flocking layer is 25-100μg/mm2; the effective flocking area of the cotton swab flocking layer 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.
[0002] In order to ensure the strength of the cotton swab head and the cotton swab stick, the connection part of the present invention includes a cubic connector and a cylindrical connector; wherein the cubic connector is connected to the swab head, the cylindrical connector is connected to the swab rod, and the cylindrical connector is connected to the swab head. The cross-sectional area of the shaped connector is 25-50% of the cross-sectional area of the cubic connector.
In addition, the cubic connector and the cylindrical connector are integrally formed, and the connection point of the cylindrical connector and the cubic connector is located at the center of the side of the cubic connector.
In addition, preferably, the raw material for the cylindrical connector is one of unsaturated polyester resin, epoxy resin, silicone resin and polyurethane resin; the swab head holder is used, and the cube connector and the swab stick are made of polypropylene. One of resin, polyethylene resin, polystyrene resin, polycarbonate resin, acrylic resin and ABS resin.
In addition, the flocking fiber on the surface of the cotton swab holder is one of viscose fiber and ramie fiber, or a mixed fiber formed by mixing viscose fiber, ramie fiber and nylon fiber.
Further, the swab head holder, the swab stick, and the connecting part connecting the swab head and the swab stick are integrally formed. The total length of the medical flocking sampling swab is 13-15 cm.
