As shown in fig. 1, the utility model provides a surgical drainage bag, which is mainly used for patients needing drainage.

The drainage bag comprises a bag body 1, an upper drainage tube 3 and a lower drainage tube 2, wherein the upper drainage tube and the lower drainage tube are respectively communicated with the upper end and the lower end of the bag body. The upper drainage tube is provided with a retention joint 4, the retention joint and the upper drainage tube are connected through a three-way valve, the first end and the second end of the three-way valve are respectively connected with the upper drainage tube, and the other end of the three-way valve is connected with the retention joint. The distance between the remaining connector and the bag body is not more than 15cm, the remaining connector comprises a tube body 43, an injection valve and a control valve 44, one end of the tube body 43 is connected with the bag body, the other end of the tube body 43 is provided with the injection valve, and the control valve is arranged on the tube body and is mainly used for adjusting the flow rate of liquid in the tube body. 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.

In one embodiment, the length of the tube is 10-15cm, and the diameter is about 2 mm.

Referring to fig. 2, in one embodiment, the injection valve includes a first injection tube 41 and a second injection tube 42, one end of the first injection tube 41 is connected to the tube body, the other end of the first injection tube is provided with a first cap 4101, one end of the second injection tube 42 is connected to the lower portion of the first injection tube, and the other end of the second injection tube is provided with a second cap 4201. The whole injection valve is similar to a Y shape, and the two injection pipes are convenient to inject cross contamination among different kinds of medicines. When the injection is finished, the injection tube is sealed by the sealing cover, and the pollution of the medicine is also prevented.
