On the other hand of the present utility model, described the first self-enclosed parts are calparine cap.
On the other hand of the present utility model, described the second self-enclosed parts are calparine cap.
On the other hand of the present utility model, the calparine cap that forms described the first self-enclosed portion is connected with described the second syringe syndeton by screw thread.
On the other hand of the present utility model, the length that described sleeve pipe is stretched out in one end of described master metal needle tubing is 5-8cm, and diameter is 0.8-1.2mm.
On the other hand of the present utility model, described hose length is greater than 10cm, and diameter is 2-3mm.
By the enforcement to technical solutions of the utility model, can obtain following technique effect:
1., while bleeding for pneumothorax puncture, particularly, in the situation of pneumothorax amount 30% left and right, avoid conventional closed drainage of pleural cavity to put the defect that wound is large and puncture has a big risk that pipe causes;
2. for thoracic cavity drawing liquid, when hydrops is extracted in puncture out behind location, can exit metal nook closing member, insert flexible pipe, can avoid the damage to lung, the adjustable accommodating pipe degree of depth, reduces puncture blind area, and extension tension force is higher simultaneously, avoids negative pressure to cause obturation;
3. during for abdominal paracentesis drawing liquid, liver week, in liver, pancreas week, the diagnostic such as pelvic cavity or therapeutic puncture, insert puncture and extract metal nook closing member behind chamber, inserts flexible pipe, can avoid blood vessel etc. to close on the damage of internal organs, and can be fixed on body surface, and drain for a long time, it is convenient to change;
4. for the puncture and intubation drawing liquid of body surface or subcutaneous tissue hematoma or hydrops, rinse, indwelling for a long time, simple, effectively, wound is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of puncture needle of the present utility model.
