Negative pressure drainage tube for orthopedics department

Abstract

The invention discloses a negative pressure drainage tube for the orthopedics department. The drainage tube comprises an in-vivo implantation drainage tube body and an in-vitro connection tube; the in-vivo implantation drainage tube body is of an integrated structure, in-vivo metal wire introduction tubes are fixedly arranged on the exterior of the in-vivo implantation drainage tube body, a main drainage tube body and two flushing tubes are arranged in the in-vivo implantation drainage tube body, and drainage holes are formed in the in-vivo implantation drainage tube body and all communicatedwith the main drainage tube body. The connection tube includes an in-vitro drainage tube body, two in-vitro flushing tubes and in-vitro metal wire introduction tubes, one end of the in-vitro drainagetube body is communicated with the main drainage tube body, the other end of the in-vitro drainage tube body is communicated with a liquid collection tank through a connecting guide tube, and the liquid collection tank is connected to a vacuum pump through a pressure-reduced air transmission tube. Compared with the prior art, the negative pressure drainage tube for the orthopedics department has the advantages that the drainage tube can deeply reach an affected area for drainage, it can be ensured that waste liquid in the affected area is smoothly discharged out of the human body, clogging ofthe drainage holes due to tissues in the affected area can be effectively avoided, and meanwhile the problem of secondary pollution can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a negative pressure orthopedic drainage tube. Background technique [0002] In clinical medicine, various types of infected open fractures, osteomyelitis, septic arthritis, acute synovitis of the knee joint, and other surgical deep abscesses, empyema, and peritonitis must be treated with medicinal liquid lavage. Especially after the operation, it is necessary to drain and flush the soft tissue cavity or the joint cavity, and suck out the waste fluid. [0003] At present, doctors usually place two tubes in the patient's affected area, one of which is used as a drug inlet tube for injecting liquid medicine for flushing, and the other is used as a drainage tube for drainage and flushing of thick blood. The end of the tube is connected to an air bag through a bypass tube, and by pressing the air bag, a negative pressure is formed in the drainage tube to suck out the waste li...

Problems solved by technology

[0005] The object of the present invention is to provide a negative-pressure orthopedic drainage tube for the above-mentioned problems existing in the existing drainage tube. This drainage tube can avoid the problem of inner wall bonding caused by pressure, and can effectively avoid The blockage of foreign matter can penetrate deep into the wound for drainage, and at the same time, it can effectively avoid the problem of secondary pollution
