In the examination of human oral and nasal cavity diseases, sample sampling swabs are needed for the collection of oral epidermal cells and nasal virus samples, and the cells and samples are kept in the collection tube and transferred to the chemical examination room for examination. The sampling swab now used is provided with a ring-shaped groove on the handle, and when using this sampling swab the sampling swab is gently inserted into the oral or nasal cavity, so that the sampling swab is gently rotated 3~5 turns and slowly removed, and the extracted sample is put into the sample collection tube
The purpose of the utility model is to have a handle, connecting rod, sample head connected sequentially from top to bottom, and at least one first break mechanism with a gradually decreasing cross-sectional area from top to bottom and a second break mechanism with a gradually decreasing cross-sectional area from top to bottom on the handle The disposable sampling swab of the utility model is easy to break and convenient to take samples, and furthermore, the horizontal cross-section of said sampling swab is polygonal, which can be prevented when taking samples sliding.
It is characterized by having a handle, a connecting rod, and a sample head connected in order from top to bottom, and at least one breaking part is provided on the handle, which includes a first breaking mechanism with a decreasing cross-sectional area from top to bottom, and a second breaking mechanism with a decreasing cross-sectional area from top to bottom
Preferably, where said handle is provided with a folding part, said folding part is provided near the connecting rod end of the handle, and said folding part is provided near the connecting rod end of said handle. In the case where two folding parts are provided on said handle, one folding part is provided near the connecting rod end of the handle and the other folding part sets the handle into two sections.
Preferably, the horizontal cross section of the steering wheel is polygonal. More preferably, the horizontal cross-section of the steering wheel is hexagonal. Preferably, each folding place further comprises a third folding unit provided between the first folding unit and the second folding unit, the third folding unit being rectangular in shape.
Preferably, the first folding unit is shaped as a circular or prismatic table, and the second folding unit is shaped as a circular or prismatic table.
Preferably, said sample head comprises a sample head substrate and a nylon fleece head implanted and set on said sample head substrate.
The utility model disposable sampling swab has a handle, connecting rod, sampling head connected in order from top to bottom, and the handle has a first bending part with a gradually decreasing cross-sectional area from top to bottom, and a second disposable sampling swab with a gradually increasing cross-sectional area from top to bottom, which is easy to break and convenient to take samples. When using the disposable sampling swab of the utility model for sampling, hand-held handle will disposable swab gently inserted into the oral or nasal cavity, disposable swab gently rotate 3 ~ 5 turns, slowly remove, the extracted sample will be inserted into the sample collection tube
