Flushable thoracic drainage tube

Technical Field

The utility model relates to a medical device, in particular to a flushable thoracic drainage tube.

Background

Currently, the widely used thoracic drainage tubes in clinical practice are usually straight tubes with scales, and the tubes are classified according to their inner diameters using french catheter scale (abbreviated as Fr: 1Fr ═ 1/3mm), and the size of the chest tubes ranges from 6 to 40 Fr. The thoracic drainage tube only has a drainage function, and can not be used for carrying out thoracic perfusion or thoracic cavity flushing on a patient through the drainage tube, when the patient needs to be flushed or flushed under the conditions of empyema, hemothorax, continuous air leakage of the thoracic cavity and the like in clinic, the patient needs to repeatedly use a syringe to prick through the wall of the tube, and the risks of air leakage and infection in the thoracic cavity after the wall of the tube is damaged are increased.

Application number 201720076495.5's utility model patent discloses a thoracic drainage tube improves to traditional chest, for a silica gel body, the middle part is provided with the fixer, and its cotton pad of fixer bonds firmly with patient's skin, and sleeve pipe and silica gel body firm in connection, and thoracic drainage tube can not slide, drop, and fixed good reliability. Simultaneously, the medicine injection tube and the injection joint are arranged, so that when drainage is performed, the medicine can be injected into the thoracic cavity of a patient through the medicine injection tube and the injection joint. However, this design has the disadvantages that: firstly, the washed drainage tube is too thin, and the operability is poor for a patient needing thoracic cavity perfusion; secondly, the front end of the flushing pipe is easy to block when in empyema or hemothorax and can not play a due role. To this end, we propose a flushable intrathoracic drain.
