The syringe port is provided with wiper block provided with side.
When in use, medicine is pumped into syringe for the device of the present invention, continues to move syringe piston to syringe end
End, the syringe needle of needle body is downward, liquid medicine is located at injection-tube lower end, jitter injection pipe moves up medicine bubble, to
The piston rod of lower pushing syringe, the gas in needle body is discharged, needle body is inserted into thoracic cavity, injected medicine to diseased region, treat
After injection, needle body is moved at hydrops, rubber soft drawn bar is stuck on the piston rod of syringe, promotes piston rod, it is living
Stopper rod drives rubber soft drawn bar that hydrops is pumped into puncture needle, it is important that hydrops quickly can be pumped into by device of the invention
Puncture needle, while the air in syringe is pushed into thoracic cavity by syringe, is made intrathoracic negative pressure consistent all the time, will not be caused
Situations such as uncomfortable in chest, bigger injury will not be brought to patient, what is more important will not cause visceral pleura increasingly to press close to wall
Layer pleura, without adjusting the position of needle body syringe needle, substantially reduces and visceral pleura, internal organs is damaged, further,
In use, drawstring can be pulled by liquid suction pipe and elastic gusset stretch bending, liquid bulk so is being extracted, syringe enters the gas in thoracic cavity
Body will not hydrops contact, bubble will not be produced, do not influence drawing liquid.
Example IV is distinguished as with embodiment three, when injection position wants syringe to be inverted, the piston of the syringe
Bar is connected with piston thread, and the face of syringe and piston contact is provided with projection, and piston rotation, piston are prevented when removing lower piston rod
Upper screwed hole is corresponding with the hole of needle body, and after having injected, piston rod is screwed into new piston, and rubber soft drawn bar is stuck in into piston
On bar, promote piston rod that air is pressed into thoracic cavity again.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff is made to technical scheme, without departing from technical solution of the present invention
Spirit and scope, all should cover among scope of the presently claimed invention.
