ABSTRACT:
Invention relates to catheter placement devices for peripheral blood vessel catheterization with protected needle tip and shortened length in a transport position (see FIG.31). In the transport position (FIG.9), the needle and catheter units (1and5) are held inside the handle (8). User transposes the needle and catheter units into a duty ready position (FIG. 6), wherein the needle unit is engaged with the handle distal end and a catheter hub (7) protrudes distally out of the handle. After catheter insertion into patient vein, user disconnects the needle unit and handle allowing the needle unit retraction by a resilient member (11) into the protection position. The trigger and transposing means (22) location enables the apparatus single handed control. The fixation means (31) in the protection position eliminates repeated needle unit advance. It can be used rubber or spiral spring resilient members and the catheter hubs with foldable side wings and side port.
