Further, upper portion rubber buffer and lower part rubber buffer pass through the connecting strip and connect, the upper portion rubber buffer is used for plugging up diluent application of sample lid upper portion, the lower part rubber buffer is used for plugging up the liquid outlet of diluent application of sample lid, prevents that diluent application of sample lid from receiving the pollution.
Furthermore, the inside internal thread that is provided with of diluent application of sample lid, the lower part is provided with the liquid outlet, can set up the diluent in advance in the diluent application of sample lid.
Furthermore, the air bag is arranged at the upper end of the handheld part, and the solution in the diluent sample adding cover can be extruded out by pressing the air bag.
Further, the hand-held part is hollow and is provided with a rubber ring and an external thread, and the rubber ring prevents the solution from seeping out.
Furthermore, a channel is arranged inside the rod body, so that gas in the air bag enters the diluent sample adding cover.
Further, body of rod upper end is connected with handheld portion bottom, and the lower extreme is connected with the cotton swab, the cotton swab is used for gathering the secretion.
Further, the internal thread and the external thread can be matched, so that the diluent sample adding cover is installed on the swab.
Through the technical scheme, the utility model has the following technical effects:
the device realizes the functions of sampling, diluting and adding sample, is simple to operate, does not need to move liquid and dilute for multiple times, reduces the possibility of sample pollution and reduces the risk of contact between medical staff and the sample.
The volume of the diluent preset in the diluent sample adding cover is certain, and compared with the action that a dropper needs to suck and extrude, the volume of the dropping liquid is easier to control.
