The purpose of arranging the indwelling joint is to inject medicine into the abdominal cavity through the indwelling joint in the drainage process so as to achieve the purposes of diagnosis and treatment. For example, some patients need to inject the sub-blue into the abdominal cavity after operation, and the indwelling joint can facilitate medicine injection, avoid puncturing holes and prevent bacteria from flowing backwards. The upper drainage tube is provided with a flow limiting valve which is mainly used for adjusting the flow rate of liquid in the drainage tube. In the using process, the upper drainage tube is connected with the abdominal cavity delivery tube of the patient, and the lower drainage tube is blocked. When the connector is not used, the three-way valve is adjusted, the upper drainage tube forms a passage, the port of the indwelling connector is closed, and when the medicine needs to be injected, the passage to the drainage bag is closed, so that the medicine can flow back upwards to enter the abdominal cavity.
