Abstract
The utility model discloses a medical instrument, in particular to a puncture needle used for abdominocentesis, pleurocentesis and suction of hydrops suction, comprising a puncture needle (1) and a needle seat (2). The utility model is characterized in that the back of the needle seat (2) is connected with a tee (3); a pintle (7) for connecting an injector or a liquid storage device is arranged on a pipe branch of the tee (3). The utility model has the advantages of integration of puncture and suction of the hydrops, convenient needle holding and mounting for clinical application and avoidance of multiple puncture.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, in particular for puncture with extract the puncture needle of hydrops out from thoracic cavity or abdominal cavity.
Background technology
Extracting hydrops out from thoracic cavity or intraperitoneal is one of technical operation common clinical, at present, known thoracic cavity and abdominal paracentesis apparatus are made up of the rubber hose that piercing needle and its afterbody connect, operator need be under assistant's cooperation, connect or pull up to repeated multiple times syringe, and with mosquito forceps clamp rubber hose repeatedly, loaded down with trivial details because of its operation sequence, waste time and energy, and rubber hose is damaged easily by clamp, and careless slightly thoracic cavity or the intraperitoneal of also air may being bled causes adverse consequences.
The utility model content
In order to overcome the above-mentioned deficiency of existing puncture needle, the purpose of this utility model provides a kind of P﹠S hydrops that integrates, and avoids the good puncture needle of clamp and sealing.
The technical scheme that its technical problem that solves this utility model adopts is: this utility model is made up of piercing needle and needle stand, it is characterized in that being connected with tee T behind the needle stand.
Described tee T comprises straight tube and a bypass branch straight-through with piercing needle, is equipped with pintle on two arms, and tee T connects syringe or sump assemblies by pintle.
The beneficial effects of the utility model are: (1) integrates the P﹠S hydrops, avoids clinical repeatedly puncture; (2) being convenient to hold pin when thoracic cavity and abdominal paracentesis fixes.One of them arm of tee T can be directly used in the suction hydrops, avoids clamp; (3) good sealing effect; (4) the directly dosing of one of them arm of tee T reduces seepage.
