Abstract
An improved venipuncture device comprises a catheter having a catheter hub at one end with a needle having a needle hub at one end and a sharpened tip at the second end extending through the catheter and catheter hub. The needle is adapted for insertion and removal from the catheter. The improvement comprises a penetrable elastic sealing member sealed within the catheter hub. A compression mechanism compresses the sealing member in the same direction as the axis of the sealing member, thereby effectively resealing the opening through the sealing member created by withdrawal of the venipuncture needle.
