Abstract:
Objective To design a portable intramedullary injection device to facilitate visualized precision puncture.Methods The portable intramedullary injection device was mainly composed of a holding shell,a display,a puncture needle,a controller and a power supply.The holding shell had a L-shaped structure,which was made of new high-performance thermoplastic resin and was provided with a polyethylene-vinyl acetate copolymer non-slip adhesive tape at its handle;the display was made of transparent nano-microcrystalline glass;the puncture needle consisted of an inner needle and an outer needle,which was made of austenitic stainless steel;a lithium iron phosphate battery was used for power supply.Results The portable intramedullary injection device facilitated safe and rapid puncture,and had the function of real-time monitoring of puncture pressure and depth.Conclusion The portable intramedullary injection device realizes visualized precision puncture with high convenience,portability,safety and durability,and contributes to enhancing the success rate for casualty treatment.[Chinese Medical Equipment Journal,2024,45(11):109-112]
