E7 protein self-home detection cervical brush and inspection method therefor

The present invention provides a cervical brush and its inspection method for E7 protein home inspection. Swing components include a shaft, baffle, sleeve, telescopic rod, piston rod, piston barrier, deformation layer, and convex strip. The shaft hinges in the sampling brush Close to the inner wall of the tip of the brush head, the baffle is swinging on the side of the shaft, the sleeve is inlaid on the end of the baffle, the telescopic rod slides the nested at the end of the sleeve, and the piston rod slides on the inner wall of the one end of the sleeve. The layer is embedded in one end of the telescopic rod near the sleeve, the piston is inlaid on one end of the deformation layer, and the convex strip is located on both sides of the deformation layer. It can be retracted to the interior of the sampling brush again. After the brush head is returned, the end of the baffle is lost to the squeezing support. The baffle can return through the axis. After the brush head is sampled, the brush head is sealed again.
