The compression time will be measured with a stopwatch so that it is objective and accurate, although the compression times range from minute to minute.

An initial 2-week observation phase (phase 1) will establish a reference time for each patient using the most common puncture technique in the department: bevel up.

We will evaluate the patient's reference time by counting the time of compression using a stopwatch for 2 weeks (ie 6 sessions) and we will take an average.

A draw will determine for each patient the order in which the direction of the needles will be used.

After this determination of the reference time, the patient will enter two successive phases where it will be punctured bevel up (phase 2) and then down (phase 3) or vice versa following the draw.

The primary endpoint is the compression time required for hemostasis after needle removal, which is stable over a 3-week period.
