Claims

1. A pre-treatment mechanism applied to an automatic sampling module, characterized in that, The system includes a mixing component (1) and a breaking component (2). When the automatic sampling module injects a sample, it passes through the mixing component (1). The mixing component (1) mixes the fecal sample to be tested in the sampling tube on the automatic sampling module with the reaction solution to form the test solution. Then, the breaking component (2) breaks the sealing film on the sampling tube to collect the test solution in the sampling tube.

2. A pre-treatment mechanism according to claim 1, characterised in that, The breaking assembly (2) includes a breaking drive motor (21) and a drill bit (22) connected thereto.

3. A pre-treatment mechanism according to claim 1 or 2, characterised in that, It also includes a squeezing component (3), which, when in use, squeezes the sampling tube to facilitate sampling.

4. A pre-treatment mechanism according to claim 3, characterised in that, The extrusion assembly (3) includes a drive member (31), two sliding blocks (32) and two clamping blocks (33). The two clamping blocks (33) are respectively connected to the two sliding blocks (32), and the two sliding blocks (32) are connected to the drive member (31). In use, the drive member (31) drives the two sliding blocks (32) to move closer or further away from each other, thereby causing the two clamping blocks (33) to clamp or separate.

5. An autosampler module characterized in that, The device includes a sample holder (4), a sample propulsion assembly (5), and a pretreatment mechanism as described in any one of claims 1-4. The pretreatment mechanism is located beside the forward path of the sample propulsion assembly (5). In use, the fecal sample to be tested is placed in a sampling tube on the sample holder (4), and the sample holder (4) is moved from the pretreatment mechanism by the sample propulsion assembly (5). The pretreatment mechanism is used to perform pretreatment operations on the fecal sample to be tested.

6. An automatic sampling module according to claim 5, characterized in that It also includes a control component connected to the sample propulsion component (5) and the pre-processing mechanism. When in use, the control component detects and obtains the current position information of the sample rack (4) and sends the position information to the sample propulsion component (5) and the pre-processing mechanism.

7. An automatic sampling module according to claim 6, characterized in that It also includes an identification element (6) located at the front end of the pre-processing mechanism. When the sample holder (4) passes by the identification element (6), the identification element (6) identifies the barcode information of the sampling tube.
