Résumé
In daily care operation, it is difficult to assess the vein of patients due to various objective factors, therefore, the routine method often leaded to puncture failure or repeated puncture. Through summarized the causes and hazards of venous puncture failure, and analyzed the basic structure and working principle of the projection infrared blood vessel imager of vivo series, to explore the clinical value of vascular visualization technique in peripheral vein puncture. A series of advantages of projection infrared blood vessel imager included small, lightweight, removable, the clearly visible vein on projection and so on could be used, and under its guidance, the success rate of peripheral venous puncture in patients was enhanced and the difficulty of puncture was reduced. Besides, the difficult problem that paramedics couldn''''t easily find vessel in the puncture was resolved. Therefore, it may replace the traditional puncture plan which depended on naked eye, and may guide a reform in the field of medical care.
