<p>Safety blood pads for dialysis venipunctures comprising a multi layered or multifold gauze pads for stemming bleeding from post dialysis venipunctures to effectively reduce cross contamination among public. Such a pad has a thick gauze pad for absorbing large amounts of blood from relatively large post-dialysis punctures. Onset of homeostasis is frequently delayed for up to 1/2 an hour but can be accelerated by application of localized finger thumb pressure by the patient, the primary elements of the pad are a planar multiply absorbent pad, of up 48 gauze layers about 2x2x0.5 inches after folding, which is enclosed in a pouch of a fluid impermeable flexible film consisting of a first layer and a second layer opposite to layer, which hermetically sealed or bonded at all four sides to form seals, thereby to form a sealed pouch or enclosure, for pad, the first layer has a circular or otherwise shaped opening located near the center of layer, which constitutes the contact between the puncture and the enclosed pad is the hole in layer which further serves to permit escape of air from the pad, so as to fully utilize the blood absorbing capacity of the pad.</p> |
