For solving above-mentioned task, the solution that this practicality is also adopted is: the chest cavity indwelling device also can include guiding puncture device, inlying catheter, and inlying catheter links to each other with drainage catheter by joint; The upper port of fairlead exceeds 3 millimeters of diaphragm plates, and the upper port of fairlead to inlet tube groove upper end height should be not more than 2 centimetres, to guarantee the water seal liquid level; Drainage catheter, inlying catheter, backward flowing preventing device, fluid collection pouch are made with plastic material; Puncture needle, guiding puncture device, seal wire are made with the Stainless Steel material.
This utility model has following advantage compared to existing technology:
1, simple in structure, safe and reliable, closure is good, and liquid circulation is flowed, and has dual anti-liquid gas and pour in down a chimney the thoracic cavity measure, each device one-shot forming, and difficult drop-off has been avoided medical cross infection or pollution.
2, use easy to carry, lightly durable, the disposable use of device aseptic, and the visual different state of an illness such as pneumothorax, dense breast, hemothorax, pericardial effusion, ascites etc. are equipped with and use different model.
3, drainage effect is good, is convenient to cleaning, changes, observes, and has not only alleviated patient's misery, has also alleviated medical worker's working strength simultaneously.
4, install, nurse simply, cost is lower, and suitable especially basic hospital is applied.
