General purpose type chest cavity indwelling drainage tube

Abstract

The invention discloses a universal thoracic retention drainage tube, which comprises a double-chamber duct with flexibility and plasticity, wherein one chamber is a washing chamber, the other chamber is a drainage chamber, and the section of the washing chamber is smaller than the section of the drainage chamber; the front end of the double-chamber duct is processed into a circle shaped leading-in part, while the rear end is provided with a washing horn mouth communicated with the washing chamber and a drainage horn mouth communicated with the drainage chamber; and the inner side of the circle of the leading-in part is provided with a drainage hole communicated with the drainage chamber, while the outer side is provided with a washing hole communicated with the washing chamber. The universal thoracic retention drainage tube is provided with the drainage chamber and the washing chamber simultaneously and can simultaneously perform drainage and washing; the drainage chamber is large and not easy to block, so the drainage is more complete; a bending head design avoids damaging viscera and reduces irritant indisposition; and the universal thoracic retention drainage tube has wide application range, is suitable for treating pleural effusion, pericardial effusion and pyothorax, has low cost and can repeatedly wash and drain after once posting.

Description

technical field [0001] The present invention relates to medical devices. Background technique [0002] At present, there are a large number of patients with pleural effusion, pericardial effusion and empyema in medical practice, especially the vast majority of patients with lung cancer have pleural effusion. This kind of disease is painful, difficult to treat, and the symptoms are easy to repeat. The traditional treatment method is to repeatedly draw liquid and wash, and inject medicine. However, multiple punctures are required, and there are disadvantages such as great pain, incomplete aspiration and drainage, rapid recurrence, long treatment period and high cost. [0003] The current drainage methods include deep vein indwelling tube and pigtail catheter. The lumen of the deep vein indwelling tube is soft and easily squeezed and narrowed by the surrounding muscle tissue. The small lumen is easily blocked by fragmented tissue and blood clots; pigtail catheter It is a sing...
