Abstract
An improvement is set forth in a peripheral IV catheter assembly which comprises a needle hub having proximal and distal ends and a central bore having a flashback chamber, blood in said chamber being observable through said needle hub. A needle extends from the distal end of the bore. A catheter hub fits about the needle and has its proximal end held by the distal end of the needle hub. A cannula fits about the needle with its proximal end engaged with the distal end of the catheter hub. A flashback plug has proximal and distal ends. Its distal end can engage with the proximal end of the needle hub in blocking relation to the needle hub bore. A protector has a proximal end engagable with the distal end of the needle hub with the passage about the catheter hub, the needle and the cannula. The improvement comprises wherein the distal end of the protector is engageable with the proximal end of the needle hub with the central passage in the protector in flow communication with the central bore in the needle hub. The protector is such that blood in the passage is observable through the protector. The flashback plug is adapted intermediate its ends to engage in the passage in the protector. The flashback chamber is extended by connecting it to the central passage in the protector. Also, the flashback plug can be used in the protector to protect against contamination.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
