AI Technical Summary

Technical Problem

Existing sampling swabs need to be broken and come into contact with the preservation solution after sample collection, which can easily cause cross-contamination and disease transmission risks. This is especially difficult to handle in a campus environment, and the insufficient sealing of the sample containers can lead to leakage and contamination during transportation and reopening.

Method used

A contamination-resistant sampling swab is used, which uses air pressure in the cavity inside the storage tube to push the sampling swab away from the tube plug, avoiding direct contact and breakage. Combined with the design of the ventilation groove, it achieves sealing and air pressure release, ensuring safe storage and transportation of samples.

Benefits of technology

It improved sampling efficiency, reduced the risk of cross-contamination, ensured the accuracy and safety of samples, reduced false positive results, and improved operational safety and convenience.

Abstract

This utility model discloses a pollution-proof sampling swab for use on campus, belonging to the field of sample sampling technology. The sampling swab includes: a storage tube, a stopper, a sampling swab, and a pressing component. The stopper engages with the opening of the storage tube, and the stopper has a cavity. The non-sampling end of the sampling swab is movably connected within the cavity. The pressing component pressurizes the cavity and separates the sampling swab from the stopper. The cavity includes a pressure chamber at the center of the stopper and an insertion cavity connecting the pressure chamber to the bottom of the stopper. The non-sampling end of the sampling swab is inserted into the insertion cavity and engages. This utility model ensures that the sampling swab falls into the storage tube and is sealed for preservation, reducing the possibility of sampling and storage contamination. In the event of a cluster of infectious diseases in densely populated environments such as campuses, this utility model can be used by non-medical personnel for self-sampling, facilitating specimen preservation and preventing contamination, so that the sampled specimens can be promptly sent to medical institutions for testing.
