Description

Technical Field

[0001] The utility model relates to the technical field of medical cotton swab production, in particular to a cotton spreading device for medical cotton swab production. Background Art

[0002] Medical cotton swabs are cotton swabs used for medical purposes, usually made of cotton or rayon fibers. They are often used in medical procedures to wipe or absorb wounds or infected areas, as well as in cleaning and disinfection processes. The structure of a medical cotton swab is usually a short, flexible stick, which is characterized by its ability to absorb liquids. One end is usually flatter and is used to wipe the surface of the skin or objects, while the other end is thinner and is used to enter the wound or infected area. The main use of medical cotton swabs is to clean and disinfect wounds, abrasions, rashes, and other skin problems. They can also be used to wipe medical instruments, skin surfaces, around wounds, and to remove blood and tissue during surgery. In addition, medical cotton swabs can also be used to collect samples from patients, such as blood, sputum, or wound secretions, for laboratory tests. In the production and processing of cotton swabs, the cotton needed for production must be broken up and re-laid for subsequent processing. In the existing production process, cotton is mostly broken up by a cotton breaking device, and then the broken cotton is manually spread to subsequent processing steps. This method of first mechanical and then manual is time-consuming and labor-intensive, which reduces the production efficiency of medical cotton swabs. Utility Model Content
