Referring to fig. 1, for the utility model provides a pus drainage device, including drainage tube 100 and flushing pipe 200, drainage tube 100 has drainage tube 100 chamber to a plurality of evenly distributed's drainage hole 120 has been seted up to the perisporium of drainage tube 100, and the trailing end connection of drainage tube 100 has suction joint 110, it should be explained that suction joint 110 is by a suction duct UNICOM drainage tube 100, and suction duct's internal diameter is 2-2.5mm to this can guarantee to have sticky pus and can discharge smoothly, reduces the suction degree of difficulty. It can be understood that a suction syringe is communicated with the outside of the suction connector 110, and an operator performs suction by operating the syringe, and pus can enter the cavity of the drainage tube 100 through the drainage hole 120 and finally be discharged out of the human body, thereby completing the drainage step. The irrigation tube 200 is connected to the drainage tube 100 and is coaxially arranged with the drainage tube 100, the irrigation tube 200 is located in the cavity of the drainage tube 100, it should be noted that the diameter of the irrigation tube 200 is 1.45mm to 1.55mm, and the diameter of the drainage tube 100 is 3.5mm to 4mm. The flushing pipe 200 and the drainage pipe 100 are designed in an integrated manner, the whole structure is compact, and the flushing device can be further kept in a human body and relieve the discomfort of a patient. It should be noted that the lengths of the drainage tube 100 and the irrigation tube 200 are determined according to the lesion position of the patient, but are not constant, so that the drainage tube can adapt to different patients and different diseases to ensure the best drainage effect.

The irrigation tube 200 is provided with an irrigation tube 200 cavity, the tail end of the irrigation tube 200 is connected with an injection connector 210, the injection connector 210 partially extends out of the drainage tube 100 and is adjacent to the suction connector 110, the irrigation tube is mainly used for injecting liquid medicine for cleaning a focus area from the injection connector 210, pus is thick, and when the pus is difficult to be led out, the pus is injected into the irrigation tube and then diluted to avoid the pus from blocking a pipeline. The puncture needle is arranged in the cavity of the flushing pipe 200, the needle head 301 of the puncture needle extends out of the flushing pipe 200 and the drainage pipe 100, the end part of the drainage pipe 100 close to the puncture needle is a cone which is gradually narrowed towards the needle head 301, the puncture needle is mainly used for puncturing and reserving the drainage pipe 100 in a human body, the subsequent treatment process of repeated cleaning and drainage for multiple times is facilitated, the multiple puncture drainage is not needed, the whole treatment process is simplified, and the pain of a patient is relieved.

Referring to fig. 2, the utility model provides a pus drainage device is still including keeping somewhere piercing depth 320, keeps somewhere piercing depth 320 including holding needle handle 321 and locking switch 322, and drainage tube 100, flushing pipe 200 detachably connect in the one end of holding needle handle 321, and pjncture needle fixed connection is in holding needle handle 321, and drainage tube 100 connects in locking switch 322, and locking switch 322 connects in the lateral wall of holding needle handle 321. When an operator operates, the operator holds the needle handle 321 with a hand to aim at a puncture area, punctures the body after disinfection, presses the locking switch 322 after the needle head 301 reaches a preset position, loosens the drainage tube 100 and the flushing tube 200, holds the needle handle 321 to pull out the puncture needle, and finishes the retention of the drainage device. The rest of the irrigation tube 200 and the drainage tube 100 are left in the human body, and the suction connector 110 and the injection connector 210 are exposed outside for subsequent dressing change and drainage operation. The drainage device is combined with the indwelling needle device, thereby being convenient for the operation of the operator and relieving the pain of the patient.

Referring to fig. 1, the tail end of the puncture needle is provided with a limit boss 302, and the limit boss 302 can abut against the end face of the injection connector 210. The puncture needle is convenient for an operator to observe the position of the puncture needle, and meanwhile, the production and the inspection of the device are also convenient, so that the puncture effect is prevented from being influenced by the improper puncture needle or too much protrusion, and the generation of defective products is prevented, and the treatment difficulty is prevented from being aggravated.

Referring to fig. 1 and 2, at least 2 rows of drainage holes 120 are uniformly arranged along the axial direction of the drainage tube 100, and each row of drainage holes 120 are arranged at equal intervals, so that the drainage effect of pus can be guaranteed to the maximum extent. And the drainage hole 120 is a tapered hole obliquely arranged at one side departing from the needle 301, and the large end of the tapered hole is positioned on the outer wall of the drainage tube 100.
