Safety needle apparatus and method |
摘要 |
Disclosed is a safety catheter that automatically sheaths the needle upon withdrawal of the needle from a patient. The catheter can include a plunger for drawing a vacuum to draw blood or alternatively may delete the plunger and use nearly identical components with the addition of a blocking plug. The catheter also includes a cap/re-cap device that provides additional sheathing of the needle during assembly, shipping, and use of the needle. It also includes raised indicia that serves as a trademark as well as a friction gripping surface. The catheter includes improved catheter hub mounting structure as well as strengthened ribbed areas for grasping during use of the catheter.
