Adsorbent-containing hemostatic devices

Abstract

The present invention utilizes a combination of a porous carrier and an adsorbent such as a molecular sieve or an inorganic material selected from the group consisting of diatomaceous earth, glass powder or fibers, precipitated or fumed silica, kaolin and montmorillonite clays, and Ca exchanged permutites to make a more effective hemostatic device to treat wounds in mammalian animals. These hemostatic devices provide a lower heat rise to the skin as compared to direct application of zeolites to the skin.

Description

Background of the invention [0001] The present invention generally relates to the hemostatic use of inorganic materials and adsorbents. In particular, the present invention relates to inorganic materials and adsorbents incorporated into an adsorbent medium, such as a nonwoven or film, in which these adsorbents are present in sufficient quantities to prevent blood loss while reducing the amount of water due to adsorption of the adsorbent. The resulting temperature rise is minimized. [0002] Wounds are usually classified as acute or chronic, depending on the treatment orientation. Acute wounds resulting from trauma or surgery include wounds such as actively bleeding wound sites, eg, wounds with detectable, unclotted blood. Rapid control of local bleeding from active bleeding wound sites is important in wound management, especially in the management of trauma, such as that caused by military exercises or surgery. [0003] Conventional methods of hemostasis, such as manual pre...
