초록 ▼

A medical IV catheter is described comprising a needle cannula having a distal point, a proximal end and further having a shaft with a circumference, a tip protector having a base the tip protector defining an opening to receive the needle cannula shaft and the tip protector is slideably mounted thereon, a biased tab and a clip coupled to the tip protector for blocking the tip protector opening so as to enclose the needle cannula distal point within the tip protector, a gasket coupled to the tip protector base defining an opening of a size to receive the needle cannula shaft, a crimp coupled to the needle cannula shaft impeding movement of the tip protector along the needle cannula shaft beyond a pre-determined distance from the needle cannula distal point, and a flash chamber coupled to the needle cannula at the needle cannula proximal end.

[ What is claimed is:] [1.]1. A medical intravenous catheter comprising:a needle cannula having a distal point, a proximal end and a shaft having a circumference;a tip protector of a pre-determined length having a proximal end including a base and a distal end including a superstructure, the tip protector defining an opening to receive the needle cannula shaft and slideably mounted thereon;a flash chamber having a distal end and a proximal end, wherein the flash chamber distal end is coupled to the needle cannula proximal end, the flash chamber further having walls extending from the flash chamber distal end defining a space to receive the tip protector;an anti-stick metal clip housed within the tip protector superstructure defining an opening concentric with the tip protector opening;a biased tab of a length sufficient to extend across the clip opening pivotably disposed within the clip opening such that in its first position the tab engages the needle cannula shaft and when the shaft is withdrawn, the tab pivots to occupy a second position blocking the clip opening;a formed in place gasket at the tip protector base defining an opening of a size to receive the needle cannula shaft;a crimp inscribed into the needle cannula shaft at a pre-determined distance from the needle cannula distal point occluding passage of the needle cannula shaft through the gasket opening, the pre-determined distance of the crimp being commensurate with the tip protector length such that moving the tip protector to the point where the crimp occludes the needle cannula shaft also moves the tab beyond the needle cannula shaft so as to free the tab to pivot to its second position;a catheter housing, having a catheter hub and further defining an opening, coupled to the tip protector so as to cover the tip protector and at least a portion of the needle cannula wherein the needle cannula distal point extends through the catheter housing opening;a flash plug coupled to the flash chamber proximal end.
