Abstract
A soft hemostasis pad of elastomeric material typically having a hardness of no more than about 50 Shore 00 and an upper wall having a raised profile, such as a convex shape. The pad has a central aperture extending therethrough, and a slit that extends through the pad thickness between the central aperture and the periphery of the pad.

13. The method which comprises:
placing a soft, resilient, pore-free hemostasis pad having a periphery, a central aperture, and a slit extending between the periphery and the aperture on the skin of a patient with a catheter extending through the patient'"'"'s skin and occupying the central aperture, and substantially closing the slit by tack adhesion, to suppress bleeding around the catheter. - View Dependent Claims (14, 15, 16, 17, 18, 19)
- 20. A soft, solid, transparent, pore-free pad of elastomeric material having a periphery and a hardness of no more than about 50 Shore 00, said pad having an upper wall of convex shape with a substantially flat, solid bottom, said pad having a central aperture extending therethrough, and a slit that extends through the pad thickness between said central aperture and the periphery to permit the lateral installation of a catheter or the like in said central aperture, said pad comprising an elastomeric material that contains a liquid plasticizer, whereby the material does not significantly adhere to a scab formed by bleeding under the solid bottom as the pad rests on the skin of a patient.
