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 ( 15 ) transforms the single manual operation of a tamping button ( 8 ) being the one end of a plunger ( 14 ) into the retraction of a pusher ( 5 ), which has been used to insert an inner seal ( 1 ) into the vessel, and, then, the advancement of a tamping tube ( 10 ), which pushes an outer seal ( 2 ) into engagement with the outer vessel wall. In the end position of the tamping button ( 8 ), a recess ( 23 ) in the plunger ( 14 ) releases a thread ( 3 ), which tamps the inner and outer seals ( 1, 2 ) together around the intermediate vessel wall, from a retainer ( 16 ), thereby completing the third operation step. |
