The purpose of this utility model will provide a kind of bushing type thoracic cavity paracentesis pericardii needle set exactly, and it not only will have certain safety, avoids the pernicious malpractice that caused by puncture needle, and simplifies the clinical manipulation program, alleviate patient's pain if.
This utility model is achieved in that the bushing type thoracic cavity paracentesis pericardii needle set of being made up of puncture needle, sleeve pipe, two-way valve, pipette, three-way valve, discharging tube, syringe, and the needle body of its puncture needle enters sleeve pipe by two-way valve and cooperates with sleeve pipe.The needle point of pricker protrudes in outside the sleeve port.The needle stand of puncture needle cooperates with two-way valve.The nipple of two-way valve and telescopic casing seat are connected.The casing seat inner chamber is communicated with the pipette joint, and the casing seat inner chamber is communicated with sleeve pipe.Pipette one end is communicated with the pipette joint, and an end is communicated with three-way valve, other two interfaces of three-way valve, and one cooperates with syringe nipple, and one is connected with discharging tube.During use, earlier sleeve pipe is installed in by casing seat on the nipple of two-way valve, the centre bore of puncture needle along two-way valve is entered in the sleeve pipe again, the needle stand and the two-way valve of puncture needle closely cooperate.Connect pipette, three-way valve, discharging tube and syringe.Then, the sleeve pipe puncture needle is thrust skin, rely on operator's the sense that falls through, make the sleeve pipe puncture needle enter thoracic cavity or pericardial cavity, then, extract puncture needle out, close two-way valve, the pull syringe, the hydrops of thoracic cavity or pericardium is entered in the syringe along sleeve pipe, pipette, after the liquid of syringe is taken out completely, make three-way valve close the passage of pipette and syringe, open the passage of syringe and discharging tube simultaneously, liquid is discharged.Then, close the passage of syringe and discharging tube again, open the passage of pipette and syringe, continue the hydrops in suction thoracic cavity or the pericardium.
This utility model utilizes sleeve pipe to carry out imbibition, not only prevents damage in propelling lung tissue or heart, can prevent that again lung tissue from breathing or heartbeat touching puncture needle.It is after entering thoracic cavity or pericardial cavity with puncture needle with the sense that falls through, to extract puncture needle at once, and replace puncture needle with sleeve pipe.Because of the material of sleeve pipe own is to have necessarily flexiblely, its port is softish flat mouthful shape, avoids tip shape, so be difficult for damaging lung tissue or heart have been avoided the direct malpractice that causes with the puncture needle drawing liquid effectively.In addition, it needn't use mosquito forceps to press from both sides repeatedly and use sebific duct by three-way valve device, and by the three-way valve handle just can directly take out, the discharge opeing body, simplified healthcare givers's operation sequence, shorten the drawing liquid time, alleviate patient bitterly as if.
Below in conjunction with accompanying drawing this utility model is described in further details.
