During use, the tester needs to use different components to collect, dilute, add, and observe the results of fecal samples. The operation is cumbersome, resulting in a poor user experience and affecting the efficiency of the test.

[0004] Therefore, how to simplify the operating procedures of fecal occult blood test and improve the detection efficiency is a technical problem that needs to be solved urgently in the existing technology. Utility Model Content

[0005] The purpose of the utility model is to provide a colorectal cancer early screening detection device for the fecal occult blood test kit existing in the prior art. In view of the problem that the tester needs to use different components to collect, dilute, add and observe the results of fecal samples during use, the operation is cumbersome, resulting in a poor user experience and affecting the detection efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The device has a simple structure and is easy to carry, making it very suitable for home use or outdoor use.

[0020] 2. The present invention describes a colorectal cancer early screening detection device, which is provided with a pipette. In the collection operation for loose stools, the tester first opens the switch valve, and then pulls the push rod to move the piston head upward. In this way, the loose stools are sucked into the dilution chamber through the pipette under the action of negative pressure suction, completing the stool sample collection operation. Compared with the traditional sampling spoon sampling method, the design of the pipette of the present invention can facilitate the tester to collect loose stools, further improving the practicality of the present invention. In addition, the provision of the pipette in this embodiment also facilitates the discharge of the remaining dilution in the dilution chamber. On the other hand, when cleaning the dilution chamber, the tester can suck the cleaning liquid into the dilution chamber through the pipette, and then use the push rod to push the piston head to discharge the cleaning liquid from the pipette or the pipette. In this way, the cleaning operation of the dilution chamber is completed repeatedly, effectively improving the cleaning convenience of the present invention.

By using this structure, in the process of cleaning the dilution chamber 1, the sampling spoon 8 penetrates through the pipette 13, and the bristles 15 at the end of the sampling spoon 8 can wipe the inner wall of the pipette 13, so as to remove the fecal residues attached to the inner wall of the pipette 13, thereby effectively preventing the pipette 13 from being blocked in the subsequent use, ensuring the smoothness of the pipette 13, and improving the cleaning effect of the pipette 13. At the same time, by penetrating the sampling spoon 8 out of the end of the pipette 13, the sampling spoon 8 can be cleaned. Compared with the above-mentioned embodiment, the first chamber section 4 and the second chamber section 5 need to be separated first, and then the sampling spoon 8 is taken out for cleaning, which can further simplify the cleaning process of the dilution chamber 1 and improve the cleaning efficiency.

[0049] Embodiment 3: as Figure 3As shown, the early screening detection device for colorectal cancer described in the present invention, based on the above-mentioned method, further includes a base 16, and a limiting hole 17 is provided on the base 16. The second bin section 5 can be snapped into the limiting hole 17 to make the dilution bin body 1 form a vertical fixed state. With this structural setting, while waiting for the test paper to develop color, the tester can snap the dilution bin body 1 into the limiting hole 17 of the base 16 to keep the dilution bin body 1 in a vertical state, thereby preventing the dilution bin body 1 from tipping over and causing the dilution liquid to excessively wet the test paper, affecting the final test result. At the same time, this design can also facilitate the storage of the device after use, further improving the practicality of the present invention.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
