DEVICE FOR SHIELDING A SHARP TIP OF A CANNULA AND METHOD OF USING THE SAME.

摘要

A safety device for shielding a sharp tip (28) of a tubular needle (14) includes a shaft (55) sized and shaped for being received into the passage of the tubular needle (14) through a first end of the passage and extending to a second end of the passage. A shield (48) is associated with the shaft (55) and is constructed for receiving and substantially shielding the sharp tip of the needle (14). A catch (60) is associated with the shaft (55). The catch (60) prevents the withdrawal of the shaft (55) from the passage of the needle (14) when the shield (48) is shielding the sharp tip of the needle (14).
