Abstract:
Compositions that include a clay such as kaolin dispersed in a liquid such as water may be useful for promoting the clotting of blood. The compositions may be in a liquid, gel, paste, foam, or another form. Uses may include treating a traumatic injury such as in injury caused by a bullet, an explosive, a blade etc., or an injury caused during a medical procedure such as surgery.
Abstract:
A device for promoting the clotting of blood comprises a clay material in particle form and a receptacle for containing the clay material. At least a portion of the receptacle is defined by a mesh. Another device comprises a gauze substrate and a clay material disposed on the gauze substrate. Another device is a bandage comprising a substrate, a mesh mounted on the substrate, and particles of a clay material retained in the mesh. A hemostatic sponge comprises a substrate, a hemostatic material disposed on a first surface of the substrate, and a release agent disposed on a second surface of the substrate. The release agent is disposed on the wound-contacting surface of the substrate. When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.
Abstract:
Disclosed are device for promoting the clotting of blood comprising a clay material and a release agent. In some embodiments, the clay material is disposed within a substrate and the release agent is disposed within a mesh. The release agent can be configured to make direct contact with a bleeding wound when the device is in particle form and the clay material can promote hemostasis.
Abstract:
This disclosure relates to devices for promoting the clotting of blood in human beings or animals, or hemostatic devices. These devices may comprise a fibrous material or materials comprising one or more fibers such as a gauze or a cloth. Some of the fibers in these materials or devices may comprise a macromolecular material and a hemostatic hemostatic additive material such as kaolin or another clay.
Abstract:
A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.

Abstract:
A radiographic composition for promoting the formation of clots in blood includes a zeolite and iodine. A device for promoting the clotting of blood at an internal wound site includes a catheter; a delivery instrument insertable through the catheter; a radioopaque blood clotting agent that deliverable through the delivery instrument; and a positive pressure apparatus that can dispense the blood clotting agent to the wound site through the delivery instrument. A system for radiographically imaging an internally bleeding wound includes means for delivering a radioopaque blood clotting agent and means for radiographically imaging the radioopaque blood clotting agent. A method of imaging an internally bleeding wound includes the steps of inserting a catheter into a patient; advancing the catheter to a point adjacent the bleeding wound; depositing a radioopaque zeolite at the bleeding wound; and imaging the radioopaque zeolite to monitor blood-clotting caused by the zeolite.
Abstract:
Devices in which components of medical kits are carried are identifiable by means other than by the naked eye. The means for identification is attached to or integral with the device and may comprise raised and lowered surfaces that can be read by touch; serrations disposed on an edge or surface; a fluorescent coating viewable under infrared or ultraviolet light; or a pattern that is viewable using a thermal imaging device such as night vision goggles. A package for retaining a medical item includes an identifying element of a material that is selectively viewable in response to light attributes of the material. A device for the visual identification of a package containing a medical item includes an identifying element comprising a material that is visually discernible in reduced-light environments via the use of night vision devices.
