Abstract
The invention relates to a loading device provided with a tamping mechanism with which two or three functional operations needed in the sealing of punctures in blood vessels can be sequentially executed in one single manual operation. In a preferred embodiment of the tamping mechanism, a cam curve () transforms the single manual operation of a tamping button () being the one end of a plunger () into the retraction of a pusher (), which has been used to insert an inner seal () into the vessel, and, then, the advancement of a tamping tube (), which pushes an outer seal () into engagement with the outer vessel wall. In the end position of the tamping button (), a recess () in the plunger () releases a thread (), which tamps the inner and outer seals () together around the intermediate vessel wall, from a retainer (), thereby completing the third operation step.
