During urine collection, medical staff or patients usually use a dropper and other tools to take a certain amount of urine, and then transfer the quantitative urine to the urine culture bottle. The overall process is complicated, and involves switching multiple containers, increasing the workload and time cost of medical staff or patients. Relatively, multiple tools need to be provided, which may affect the reliability of the pathogenic bacteria detection results. At the same time, the urine is highly likely to be in contact with the external environment during the process of taking and transferring, and the pollution risk is high. Moreover, it is difficult for patients to operate by themselves, especially for patients with difficulty in movement or cognitive impairment, which affects the quality of urine samples and the patient experience.

[0004] In summary, the urine culture bottle in the prior art is generally only provided as a container, and additional tools are needed to achieve quantitative taking during urine collection and detection. The design of multiple container switching makes the operation more complicated. UTILITY MODEL CONTENT
