Description
Technical field
This utility model relates to a kind of pleura cavity puncture needle, belongs to the technical field of medical apparatus aspect.
Background technology
At present, clinically can adopt pleurocentesis determination hydrops character, drawing liquid or bleed alleviates intrathoracic pressure compels and at intrathoracic injection medicine etc.In piercing process, first clamp the drainage tube after puncture needle with mosquito forceps, fix site of puncture local skin with left hand, the right hand holds puncture needle, vertically slowly thrust through rib upper limb along site of anesthesia, connect syringe, unclamp mosquito forceps by assistant, assistant assists fixing puncture needle with mosquito forceps simultaneously, its drawback is, needing two people to coordinate can complete operation, utilizes mosquito forceps to block drainage tube to stop drawing liquid, easily cause drainage tube damaged, thus cause the problems such as pleural space air inlet; Utilize mosquito forceps to fix puncture needle, easily cause needle point to slide, cause pulmonary lesion.Two people operate and easily pollute.
Summary of the invention
For the deficiency that above-mentioned technical problem exists, the purpose of this utility model is to provide a kind of pleura cavity puncture needle.
A kind of pleura cavity puncture needle, comprise, puncture needle connects drainage tube through connector, be provided with joint at drainage tube away from one end of puncture needle, it is characterized in that: be movably installed with in criss-cross fixed mount on puncture needle, be provided with needle clip seat in the side of fixed mount, its needle clip seat is connected to form along buckle by under edge on needle clip seat and needle clip seat, needle clip seat is all filled with rigid foam along interior under edge and needle clip seat, is used for the puncture needle that is fixedly clamped, be provided with tack coat at fixed mount away from needle clip seat side; Drainage tube is set with switch, and in switch, middle part is provided with projection and corner block, and upper end is provided with oblique edge and block.
Described projection and corner block correspondence are arranged, and when closing switch, tiltedly along being connected to inside block, make corner block and projection compress drainage tube; When opening switch, stirring block, making tiltedly along departing from block.
This utility model has structure simple, and reasonable in design, easy to use, one man operation just can complete puncture, does not re-use card blood pincers, avoids occurring drainage tube disrepair phenomenon.
