Description

Technical Field

[0001] The present invention relates to the technical field of tumor marker detection, and in particular to a self-service sampling device for tumor marker detection. Background Art

[0002] Tumor markers, also known as tumor markers, refer to substances that characteristically exist in malignant tumor cells, or are abnormally produced by malignant tumor cells, or are produced by the host's response to tumor stimulation, and can reflect the occurrence and development of tumors and monitor the tumor's response to treatment. Tumor markers exist in the tissues, body fluids and excretions of tumor patients and can be detected by immunological, biological and chemical methods. In addition to urinary tract tumor biomarkers, urine also contains tumor biomarkers of various other organs. This is because the kidney is an organ that produces urine and has a rich blood supply. It is an important organ for excreting metabolic waste from the human body. Markers with very low concentrations in urine can accumulate through the high rate of renal turnover and concentration functions, leading to increased concentrations. Non-invasive urine biomarkers are beneficial for cancer patients in detection, treatment decisions and prognosis.

[0003] Before testing for tumor markers in urine, patients are required to take urine samples on their own. However, most general sampling devices use a small urine cup to collect urine, and then introduce it into a test tube for testing. However, since the volume of the urine cup is too small to collect the total amount of urination at one time, in order to avoid cross contamination, the urine needs to be collected in the middle of urination when the urine cup is collected. This makes the operation very inconvenient and prone to unstable operation, resulting in urine splashing. Summary of the invention
