1. The method which comprises:
- applying a first, soft pad to the skin of a patient, said pad consisting essentially of an elastomer having a hardness of no more than about durometer 50 Shore 00;
passing a medical cannula through the pad into the tissue of the patient;
overlying the first, soft pad and medical needle with a second, soft pad of elastomeric material having a hardness of no more than about 50 Shore 00, said second pad having a raised-profile upper surface and a generally flat bottom; and
securing the second, soft pad in place on said first, soft pad and said medical needle cannula with pressure against the skin.

Abstract
A soft hemostasis pad of elastomeric material having a hardness of no more than about 50 Shore 00 and an upper surface of raised profile, such as a dome. The pad may be connected by a hinge with another, generally flat-bottom pad of similar elastomeric material and hardness of no more than about 50 Shore 00. The pad may rest on the skin and be penetrated by a needle or other cannula. The pad with the raised profile may then be placed over on top of the needle, for improved hemostasis and sealing when the cannula is removed and before, facilitated by the application of gentle pressure, such as by tape that holds the pads in place.

- 7. A first, soft, hemostasis pad of elastomeric material having a hardness of no more than about 50 Shore 00, said first pad having a generally flat and non-absorbent lower surface and a second, soft pad peripherally connected by a hinge to said first, soft pad, said second, soft pad comprising an elastomeric material having a hardness of no more than about durometer 50 Shore 00, said second soft pad having a raised profile upper surface and a generally flat, lower surface, said second, soft pad being capable of folding by said hinge to abut the flat, solid bottom of the second, soft pad against a major face of said first, soft pad.

17. The method which comprises:
-
applying a first, soft pad to the skin of a patient, said pad consisting of essentially of elastomer having a hardness of no more than about durometer 50 Shore 00; passing a medical needle through the first pad into the tissue of the patient; overlying the first, soft pad with medical cannula with a second, soft pad of elastomeric material having a hardness of no more than about 50 Shore 00, said overlying taking place by folding said second, soft pad about a hinge connected to the first, soft pad, to place said second, soft pad on top of said first, soft pad and needle, said second soft pad having a raised profile upper surface and a generally flat bottom; securing the second, soft pad in place on said first, soft pad and said medical needle with pressure against the skin; and thereafter withdrawing the cannula from the patient without removing the first and second, soft pads from their positions, whereby bleeding is suppressed. - View Dependent Claims (18, 19, 20, 21)
