Abstract

A sticking material for hemostasis has a flexible strip-shaped base member having a high recovery property, a main surface, and side edges extending in a first longitudinal direction. An adhesive layer is disposed on the main surface of the base member. A pad is disposed on the adhesive layer and extends in a second longitudinal direction substantially transverse to the first longitudinal direction such that a space is defined between the pad and each of the side edges of the base member. The pad is of a size sufficient to exert pressure at a puncture area including punctures of both a blood vessel and a skin surface. The pad has a slight elasticity and a hardness capable of securely exerting pressure on the punctures by a shrinking action of the base member when the base member is adhered to the skin surface while being stretched to secure the pad over the punctures. A pressure plate having a width equal to or less than the width of the base member may be interposed between the base member and the pad to enable the pad to be more strongly pressed against the puncture area. The pressure plate has a size greater than the size of the pad. Hemostasis is conducted readily and effectively without the possibility of blood leaking from the puncture area.
