1, Make sure that the disposable cervical sampling brush is independently packed intact and unbroken before operation, and check whether the cell preservation tube is broken or leaking fluid.
2, Remove the disposable cervical sampling brush and adjust it until the disc of the sampling brush is between bayonet A and B and the brush head of the sampling brush is not exposed in the trocar.
3, the operator holds the anti-slip pattern of the cannula and inserts the swab (at this point the disc of the sampling brush bar is between bayonet A and B) slowly from the vagina to the ectocervix (at this point there should be slight resistance, but no pain).
4. Holding the trocar in place with one hand, push the sampling brush gently so that the disc of the brush bar passes through the internal bayonet A of the trocar, indicating that the head of the brush is exposed to the trocar, and then continue to push in gently for about 1 cm so that the brush head is completely exposed to the trocar and touches the ectocervix; hold the brush against the handle and turn the brush slowly in the same direction for 4-5 revolutions to collect enough cervical cells (note that the force should be moderate, too light to get enough cells, too heavy may damage the cervix causing bleeding).
5. After collecting the cells, hold the trocar in one hand and pull the brush handle outward with slight force in the direction shown in the figure, so that the disc of the sampling brush bar is returned to the inside of the trocar between bayonet A and bayonet B. Slowly withdraw the casing and the sampling brush together from the vagina (push the brush head out of the casing)
6, fix the casing with one hand and push the brush handle with the other hand in the direction shown, so that the disc of the sampling brush bar passes through the bayonet A, exposing the brush head outside the casing until the groove at the end of the brush head is exposed (be careful not to touch other objects with the brush head); (product performance for collecting viral specimens)
7, open the cell preservation tube (containing 2ml of volatile cell preservation fluid) with the sampler, immerse the brush head into the liquid surface, fix the bottle and stir it fully for more than 10 times to completely release the collected specimen in the cell preservation fluid (if it is inadvertently stained with liquid, just rinse it with water); (break the brush head)
8. Fix the cell preservation tube with one hand, break the self-sampling brush from the groove at the end of the brush head as shown in the figure, keep the brush head in the cell preservation fluid, tighten the cap of the cell preservation tube, discard the brush handle and the cannula part.
Ltd. specializes in the production of nylon flocked sampling swabs, nylon flocked swabs are widely used and are ideal when used for bacteriological sample processing, virology cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic based testing, and forensic identification. It can also be used for pharyngeal sampling of respiratory viruses such as influenza, swine flu, avian influenza, and hand, foot and mouth.
