| titleOfInvention | Novel puncture needle for amniocentesis |
| abstract | The utility model relates to a novel puncture needle for amniocentesis. The novel puncture needle comprises a needle tube. The novel puncture needle is characterized in that the outer wall of the lower end of the needle tube is provided with scales, the other end of the needle tube is provided with a switch valve, the switch valve is connected with a T-shaped three-way type drainage tube, the inside of the needle tube is sheathed with a needle core, and the top part of the needle core exposes out of the three-way type drainage tube. By considering the convenient connection and installation of a collector, the three-way type drainage tube is provided with a drainage connecting valve. The novel puncture needle has the advantages that the structure is simple, and the operation is convenient; the depth of needle inserting can be conveniently and accurately judged by an operator; and the T-shaped three-way type drainage mode solves the problem of injury to tissues of fetuses and mothers by the shaking of the needle tip when two tubes of amniotic fluid are required and a syringe is replaced during the suction of amniotic fluid. |
