[0002] In current medical practice, the collection of drainage fluid as culture solution or diagnostic sample is an essential link, which is of great significance for the diagnosis, treatment monitoring and prognosis evaluation of infectious diseases. However, the existing methods for extracting drainage fluid have significant limitations and challenges. First of all, traditionally, medical staff need to strictly disinfect a designated position on the drainage tube, and then use a syringe to directly pierce the tube wall of the drainage tube to extract the liquid. This process is not only cumbersome, increasing the operation time, but also may cause minor damage to the drainage tube, thereby increasing the risk of patient infection. In addition, if the operation is improper, it may also cause the drainage fluid to overflow and contaminate the surrounding environment, posing a threat to medical safety. Secondly, the hanging method of the drainage bag also directly affects the comfort of the patient and the convenience of nursing. In the ward environment, not all beds are equipped with special hooks, resulting in a big problem in hanging the drainage bag. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a drainage device convenient for extracting culture solution to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a drainage device convenient for extracting culture solution, including a drainage bag, on which scale lines and writing marking parts are printed. A cross drainage valve, a hanging fixing belt, a drainage tube and a clip are arranged on the drainage bag. A branch pipe, a pipeline fixing mechanism, a stop clamp and a flow regulator are arranged on the drainage tube. The inner end of the branch pipe is communicated with the inner end of the drainage tube, and a connector is arranged on the branch pipe, and the connector is connected with a heparin cap for syringe puncture to extract culture solution. The clip is composed of a fixed seat, a clamping plate and a limiting strip, and is used for clamping and fixing the hanging fixing belt. One end of the fixed seat is rotatably connected with one end of the clamping plate, and a plurality of limiting strips are horizontally arranged from top to bottom on the inner walls of the fixed seat and the clamping plate. The plurality of limiting strips on the inner wall of the fixed seat and the plurality of limiting strips on the inner wall of the clamping plate are arranged alternately. A clamping hole is arranged on the fixed seat, and the clamping hole is in clamping connection with a spring clamping block arranged at the corresponding position of the clamping plate.

[0005] The beneficial effect of the utility model is that during the use of the utility model, it is not only convenient for medical staff to extract the culture solution, but also does not cause damage to the drainage tube. At the same time, during use, it is also convenient for hanging and fixing the drainage bag, which can increase the convenience of extraction and drainage.

[0006] For the convenience of collecting and discharging the drainage fluid:

[0007] As a further improvement of the above technical solution: The cross drain valve is located at the middle position of the bottom end of the drainage bag, while the drainage tube is located at the middle position of the top end of the drainage bag.

[0008] The beneficial effect of this improvement is that by setting up the cross drain valve, it is convenient to drain the drainage fluid in the drainage bag when it is opened. By setting up the drainage tube, it is convenient for the drainage fluid to flow into the drainage bag for collection.
