Detection apparatus

Abstract

The present invention provides a test device, including a sample collector (200) and a test kit (300), the test kit (300) uses to store a test strip (100). The sample collector (200) includes a sampling head (203), a handle (201) and a connecting portion (202) between the sampling head (203) and the handle (201); and the test kit (300) includes a sample addition hole (3) and a buckle (10). When the sample collector (200) is placed into the test kit (300), the connecting portion (202) of the sample collector (200) is fastened to the buckle (10) of the test kit (300), and the connecting portion (202) of the sample collector (200) includes a wedge-shaped structure (202a) wide at the top and narrow at the bottom, the wedge-shaped structure (202a) being located at the point (202) where the sample collector (200) is in fastening fit with the buckle (10). By using the wedge-shaped structure (202a) of the connecting portion (202) of the sample collector (200) of the present invention, it is easier for the connecting portion (202a) to pass through the buckle (10) of the test kit (300), thereby reducing the squeezing force applied to the sample collector (200), and then reducing the impact of the sample collector (200) on the squeezed liquid sample, thereby effectively reducing the splashing of the liquid sample and avoiding contaminating the operator and the environment by the splashed sample.
