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.
Claims24
A blood-clotting agent comprising:
- a composition comprising clay dispersed in a liquid medium, wherein the clay is less than about 10% by weight of the composition;
- and
- wherein the composition including the liquid medium and clay has a viscosity of about 1000 cP or less.
A hemostatic composition comprising:
- a clay dispersed in an aqueous medium;
- wherein the composition is a liquid which is substantially free of visible clay particles;
- and
- wherein the composition is sterilized.

A hemostatic device comprising:
- a vessel which contains a hemostatic composition,
- wherein the hemostatic composition comprises a clay dispersed in an aqueous medium;
- wherein the composition is a liquid which is substantially free of visible clay particles;
- and
- wherein the composition is sterilized;
- and
- a dispensing component in fluid communication with the vessel;
- wherein the device is configured so that the dispensing component is capable of dispensing the hemostatic composition from the vessel to a bleeding area of an animal or person.
5 more elements
A hemostatic composition comprising:
- a liquid comprising a first component of a kaolin, wherein the first component of the kaolin is prepared by a process comprising:
- dispersing the kaolin in an aqueous medium;
- and
- separating the first component of the kaolin from a second component of the kaolin;
- wherein first component of the kaolin has an average particle size which is smaller than an average particle size of the second component of kaolin.

- a hemostatic device comprising:
- a vessel comprising an interior volume configured to contain a liquid;
- an orifice in fluid communication with the interior volume comprising a rim surrounding the orifice, wherein the rim is configured to form a seal with a part of an animal body or a human body;
- a fluid input component configured to provide a liquid to the interior volume of the vessel;
- and
- a fluid output component configured to allow liquid to exit the interior volume of the vessel;
- and
- a composition a hemostatic composition,
- wherein the hemostatic composition comprises a clay dispersed in an aqueous medium;
- wherein the composition is a liquid which is substantially free of visible clay particles;
- and
- wherein the composition is sterilized.
