Integrated flushing drainage tube special for sternal infection wound

Abstract

The invention discloses an integrated flushing drainage tube special for a sternal infection wound, which comprises a flushingcavity.A drainage cavity part is arranged onthe outer surface of the flushingcavity, a drainage cavity grid-shaped opening is formed in the outer surface of the drainage cavity part,a flushing cavity inner tube is arranged onthe inner wall of the flushing cavity, a drainagecavity is arranged onthe inner wall of the draining cavitypart, one end of the flushing cavity is provided with a flushing cavity speed limiter and a flushing cavity flushing fluid joint,and the flushing cavity flushing fluid joint is located on one side of the flushing cavity speed limiter. According to the integrated flushing drainage tube special forthe sternal infection wound, the flushingtube and the drainage tubeare integrally designed, so that the mounting steps can be reduced, the probability of infection of a skin incision is decreased, the speed limiter is arranged to facilitate theadjustment offlushing speed according to illnessstates, 24-hour continuous flushing is available, the forming of the drainage cavity grid-shaped opening can effectively drain wound secretion and necrotic tissue to avoid clogging ,and the better use prospects are brought.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an integrated flushing and drainage tube specially used for sternal infected wounds. Background technique [0002] The drainage tube is used for clinical surgical drainage. It guides the pus, blood, and liquid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used in clinical practice. , some are used for catheterization, some are used for wounds, chest cavity, brain cavity, gastrointestinal tract, biliary tract and so on. In vitro, it prevents postoperative infection and affects wound healing, and is widely used in medical operations.

Problems solved by technology

[0003] When the existing mechanical drainage tube is used, firstly, visceral and retrosternal operations are increasing day by day. It is more common for elderly, malnourished, diabetic, COPD, and bypass patients to have non-union of sternal incision after internal mammary artery extraction. The patient base is large, and sternal incision Poor healing affects postoperative recovery, increases hospitalization time and medical expenses, and patients are often in great pain due to long hospitalization time. Secondly, one irrigation tube and two drainage tubes need to be placed after sternal debridement. The ready-made commercial pipeline needs to be modified with other pipelines, the operation is complicated and the effect is poor, and the multiple pipelines increase the workload of doctors and nurses and the risk of infection. Finally, it takes a long time to flush and drain the incision after sternal debridement, and often requires 1-2 weeks, it is inconvenient to care for multiple pipes, and it is easy to be infected
