The invention relates to the technical field of
medical equipment, in particular to a disposable central
vein puncture kit. At present, after a puncture needle penetrates through a central
vein, a guide steel wire is arranged, the puncture needle is withdrawn, the
skin is expanded through a
skin expander, and a central
vein catheter is arranged along the guide steel wire during domestic venous transfusion cathetering. The defects are that 1, the guide steel wire possibly touches the heart, so that arrhythmia is caused; 2, the
skin is expanded through the
skin expander, so that the guide steel wire is possibly bent, the
catheter is difficult to arrange, and puncture fails; and 3, the
catheter is thick, and the
central venous catheter related infection probability is high. The disposable central
vein puncture kit comprises a central vein catheter and a puncture needle, wherein a
catheter sheath is arranged outside the puncture needle and has an easily torn breakage indentation. During use, the central vein catheter is arranged through the
catheter sheath. The operation is easy, the guide steel wire is not required, the skin is not required to be expanded, the injury of a patient is lightened to a certain degree, and the related infection occurrence rate of the catheter is reduced.
