Detailed Description

Referring to fig. 1, a novel surgical cavity drainage device comprises a drainage tube 1 and a flushing tube 2, wherein the drainage tube 1 is buried and sewn into an operative incision along the direction of the operative incision, the outer end of the drainage tube 1 is arranged outside the operative incision, and a plurality of drainage holes 2 for guiding overflowing liquid (pus, blood or other tissue liquid) in the operative incision into an inner cavity of the drainage tube 1 to be discharged outwards through the inner cavity of the drainage tube 1 are formed in the side wall of the inner end of the drainage tube 1; the flushing pipe 2 is laid along the length direction of the drainage pipe 1, the inner end of the flushing pipe 2 extends to the end part of the inner end of the drainage pipe 1 so as to inject liquid medicine to be injected into the cavity of the drainage pipe, the outer end of the flushing pipe 2 extends out of the outer end of the drainage pipe 2 so as to be connected with a syringe, and the end part of the outer end of the flushing pipe 2 is provided with a pipe cap 4 so as to seal the outer end of the drainage pipe. The utility model discloses a novel art chamber drainage device's drainage tube can make art chamber (the operation incision after sewing up) communicate with each other with the outside air, thoroughly eliminates the environment that the anaerobe survived, even in case take place other fungus crowd and infect, the accessible flushing pipe washes, drainage and art chamber laxative to the art chamber to in time control, kill the anaerobe, in order to guarantee that the art chamber has better self-resuming environment, and then promote the healing of operation incision, avoided the wound to open again and led to the fact the pain for the patient.

The main function of the flushing pipe on the drainage device of the utility model is to inject the liquid medicine into the operation cavity in time, or to clean and drain the operation cavity, therefore, the arrangement mode of the flushing pipe can be outside the drainage pipe 1 (see figure 2) or inside the cavity (see figure 3) or inside the pipe wall (see figure 4), and figures 2-4 are the schematic view of the structure of the drainage pipe cut along the radial direction; as long as the purpose of injecting the liquid medicine or the flushing liquid into the operation cavity from the outer end of the flushing pipe can be achieved, the specific arrangement mode is not limited.
