CANNULA SEALING SHIELD ASSEMBLY

摘要

A cannula sealing shield assembly comprises a cannula assembly including a c annula having a proximal end, a distal end and a lumen therethrough. A hub having a n open proximal end and a distal end is joined to the proximal end of the cannula so that th e lumen is in fluid communication with the open proximal end of the hub. A shield includes an op en proximal end, an open distal end and a side wall therebetween defining a recess. The shield is removably connected to the cannula assembly so that the distal end of the cannula is c ontained within the recess. A seal plug includes a proximal end and a distal end. The seal plug has a distal position wherein the seal plug projects distally outwardly from the distal e nd of the shield for telescoping movement from the distal position to a proximal position. The se al plug including structure for sealing the cannula to prevent unpressurized fluid communicati on between the lumen and the exterior of the shield when the seal plug is in the proximal p osition.
