Abstract
The invention discloses a medical drainage tube capable of avoiding iatrogenic contamination, and belongs to the field of medical instruments. The medical drainage tube capable of avoiding the iatrogenic contamination comprises a main drainage tube, wherein a liquid inlet is formed in the front end of the main drainage tube, an injection tube is arranged on the front section, close to the liquid inlet, of the main drainage tube side by side, and the drainage tube and the injection tube are of an integrated structure and not communicated mutually. The injection tube and the main drainage tube are arranged side by side and not communicated mutually, so that the situation that drainage substances are reversely pushed to the drainage portion to cause contamination is avoided when drugs are administrated to the drainage portion of a patient. In addition, the injection tube comprises the tube wall, the tube wall is made of elastic material and form an elastic tube cavity with clearance gaps sealed, so that drainage liquid is prevented from entering the injection tube and contaminating the injection tube. The medical drainage tube capable of avoiding the iatrogenic contamination solves the problems that in the prior art, drainage and drug administrating can not be carried out simultaneously, and an existing drainage tube causes the iatrogenic contamination in the drug administrating process.
