2) introduce seal wire by the puncture needle uropore and enter the thoracic cavity, the outer seal wire of puncture needle uropore is about 5～10cm (puncture needle is about 10cm), and fixedly puncture needle is extracted in the seal wire position, and have only seal wire this moment in the thoracic cavity;

3) the seal wire tail end is stretched into the dilator front end, and pass dilator, then dilator is pushed away forward along seal wire, skin expansion and subcutaneous tissue;

4) withdraw from dilator, the seal wire tail end is stretched into sheath tip end, and from sheath pipe side opening, stretch out, the sheath pipe is inserted in the thoracic cavity, but the equal drain hydrothorax of sheath tip end and side opening is inserted intrathoracic sheath length of tube and is advisable with 5～10cm along seal wire;

5) extract seal wire, close two bifurcateds of sheath pipe immediately with the pipe clamp folder, with the aseptic protection point of puncture of applying ointment or plaster, and by the skin holder fixedly the sheath pipe on skin, use calparine cap tube sealing (sealing the sheath pipe bifurcated tail end that is not connected with drainage tube) then, patient need wash or just can open during injectable drug; Drainage bag is connected on the drainage tube, at this moment, just can have carried out the drain of hydrothorax.

Major technique feature of the present invention has: 1, avoid surgical incision skin and subcutaneous tissue, as long as puncture is by puncture needle and sheath pipe; 2, the sheath pipe is marked with scale, the doctor can easily be made accurate judgment to the degree of depth of drainage tube in the thoracic cavity, thereby need not by imaging examination, has reduced doctor's workload and patient's financial burden; 3, the sheath pipe is provided with side opening, fully the drain hydrothorax; 4, stay the near-end of pipe to be furnished with fixture drawing, can utilize surgical sutures, conduit is fixed in skin; 5, two-chamber sheath pipe, a chamber is used for drain pleural effusion, and another chamber is used for flushing, and injectable drug uses when infection and tumour patient chemotherapy; 6, drainage tube is provided with speed regulator, control drainage flow and speed; 7, be furnished with special-purpose puncture needle and seal wire, ICU doctor is single can be at the short time complete operation.

The present invention is rational in infrastructure, and complication is few, cost is low, safety simple to operate, and can independently finish by ICU doctor, be beneficial to critical patient's rescue, also be adapted at basic hospital and carry out, also can be used for the out-patient.
