摘要： A safety catheter includes a catheter hub, a catheter tube, a needle hub, a needle cannula having a tip, and a tip protector. The tip protector includes an outer member having a flexible tab configured to releasably engage with the catheter hub and release therefrom upon inward flexing of the tab. An inner member is positioned entirely within the outer member and has a portion that impedes inward flexing of the tab when disposed adjacent the tab. The inner member is axially shiftable relative to the outer member between a first position wherein the needle tip is distal of the tip protector and the inner member portion is disposed adjacent the tab to impede release from the catheter hub, and a second position wherein the tip is within the outer member and the inner member portion is no longer adjacent the tab and no longer impedes release from the catheter hub.

摘要： A safety catheter includes a catheter hub, a needle cannula having a tip, and a tip protector. The tip protector includes an outer member and an inner member therein. The outer member has a projection releasably engaging the catheter hub. The inner member has a pair of arms extending to free ends from a base. The inner member is axially shiftable relative to the outer member between a first position wherein the needle tip is distal of the tip protector and the free ends of the arms are spread apart such that the distal tip is not shielded, and a second position wherein the tip is within the inner and outer members and the free ends of the arms are brought into close proximity such that the distal tip is shielded. The inner member is entirely received within the outer member in both the fort and the second positions thereof.
