Technical Field

[0001] This utility model relates to the field of sampling devices, specifically a multifunctional anti-pollution sampling and inoculation device. Background Technology

[0002] Following an outbreak of aquatic animal diseases, on-site, real-time sample collection is necessary. Poolside sampling demands stringent aseptic techniques for pathogen isolation and identification. While employing sterilization methods such as disinfection and alcohol lamps to enhance aseptic conditions, the convenience of sampling equipment is also crucial. Currently, disposable inoculation loops are commonly used for microbial isolation and plating during field sample collection. However, existing technologies require multiple people to open the wound and select and replace inoculation loops with different aperture sizes according to actual needs, resulting in significant waste of manpower and time, and also introducing a substantial risk of contamination. Therefore, this application proposes a multifunctional, contamination-resistant sampling and inoculation device. Utility Model Content
