Research and Development of Puncture Needle Depth-controlled Device / 医疗卫生装备

ABSTRACT

Objective To research and develop a kind of puncture needle depth -controlled device. Methods Based on mechanical design principle, and with stainless steel and plexiglass as materials, the puncture needle depth -controlled device is composed of syringe, needle guard, pin pusher, scale gauge, depth-controlled nut, and locking screw and pedestal hood. Results The puncture needle depth-controlled device is suitable for different kinds of puncture needles and syringe needles, and has many advantages including operation labor -saving, controlling depth, diminishing contamination and infection, avoiding needle guard slippage and needle bending. The operation can be implemented in one minute. Conclusion The kind of puncture needle depth-controlled device is developed successfully and as new first-aid equipment is provided for war wounds or accidents scene rescue.
