[0023] The working principle here is: when it is necessary to extract wound exudate, the nurse connects the end of the syringe 2 to the drainage tube 1 and ensures that the thread at the connection is tight; next, the nurse operates the extraction mechanism 3 on the syringe 2; the extraction mechanism 3 includes a piston 301 sliding in the syringe 2 and an extraction rod 302 fixed on the piston 301; the nurse operates the extraction rod 302 to make the piston 301 slide in the syringe 2, thereby forming negative pressure to extract the exudate into the syringe 2; the external sliding connection of the drainage tube 1 A protective cover 4 and a mounting plate 5 are provided on the syringe 2; when the drainage tube 1 needs to be installed on the patient's wound, the nursing staff first slides the protective cover 4 to the outside of the drainage tube 1, and then places the mounting plate 5 around the wound, and then fixes the protective cover 4 and the mounting plate 5 through the holding mechanism 6 to ensure that the drainage tube 1 is stably placed on the patient's wound to maintain smooth drainage; a storage mechanism 7 for storing exudate is provided on the syringe 2, which is used to conveniently store the exudate; this can prevent the exudate from overflowing or polluting the environment, and also facilitates the monitoring and management of the amount of exudate.
