Description

Multifunctional integrated drainage tube

Technical Field

The invention relates to the technical field of medical instruments, in particular to a multifunctional integrated drainage tube.

Background

Chest infections are a serious complication after thoracic surgery. Among them, severe postoperative empyema is often seen in postoperative anastomotic fistula of esophageal cancer, and if treatment is not timely, the anastomotic fistula combined empyema can cause fatal complications such as great vessel hemorrhage, tracheoesophageal fistula and the like, and the death rate is very high. Clinically, when a patient is infected, in order to keep smooth drainage of a chest tube placed during an operation, a washing tube is generally placed at a pustule cavity through an operation under the condition of imaging positioning. However, the deep pus chamber is often located deep in the mediastinum, adjacent to large blood vessels, with a significant risk of irrigation tube placement, and increased surgical costs and patient pain. In addition, the traditional administration flushing has a single flushing outlet, is not beneficial to medicine diffusion and greatly limits the curative effect; the integral type pipeline that washes that uses at present mostly is the form that penetrates an infusion catheter in former drainage tube, the structure of original drainage tube has been changed, the drainage path has been hindered, cause the reduction of drainage effect, and fix the flushing pipe on the drainage tube surface, can lead to drainage tube surface unevenness, the holistic size has been increased, and then the suture of the peripheral incision of influence drainage tube, the wound infection probability has been increased, the drainage tube is in the postoperative use, the condition that can shift takes place, at this moment, need medical personnel to make corresponding adjustment, but because can't confirm its specific removal yardstick, consequently need rely on medical personnel's clinical experience to a certain extent.
