Abstract:
The new needle assembly has a long hollow handle with an opening in the near end. At the far end, the tip has a sharp hollow needle. The needle hub slides coaxially in the handle. In the hub, there is a long flashback chamber, to view blood entry. A hollow tube in the handle connects the hub to the near end opening, but only when the needle tip is extended.
