Abstract
Wound dressing assembly including (i) blood-clotting mold device having an enclosure defined between walls of a main body and a removable closure over an opening and configured for introduction of blood thereinto, and (ii) coagulation initiator in amount sufficient to coagulate blood introduced into the enclosure to form a blood clot. The formed blood clot is transferable onto a wound. Method for preparing a wound dressing by introducing a volume of blood into the enclosure of the blood-clotting mold device, maintaining the blood within the enclosure for time sufficient to permit clotting of the blood to obtain a blood clot; removing said the closure to open the enclosure; and extracting the blood clot from the enclosure. The formed blood clot may be used in a method for dressing a wound by fixation of the clot onto the wound.
Core Innovation
The invention relates to a wound dressing assembly and a blood-clotting mold device for preparing and applying a wound dressing. The mold device includes an enclosure having the shape of a blister with a blister depression, a blister wall, and a flat rim, sealed by a removable closure. The enclosure contains a blood clot supporting matrix and a coagulation initiator.
A volume of blood is introduced into the sealed enclosure, where at least one of the blister wall and the closure is needle pierceable. The introducing includes piercing one of the blister wall or closure with a needle and injecting the blood therethrough, and the blood is maintained for a time sufficient to permit clotting. The blood clot forms on the gauze included in the blood clot supporting matrix.
After clotting, the removable closure is removed to open the enclosure and the blood clot is extracted from the enclosure with the matrix. In dressing a wound, the blood clot is thereby made transferable onto the wound, followed by fixing the blood clot onto the wound. The disclosed enclosure and closure arrangement supports encapsulation and extraction of the clot complex using removal of the closure.
Claims Coverage
The partial content identifies two independent claims, with a shared set of inventive structural and procedural features including a blister-shaped sealed enclosure, needle-pierceable wall or closure, a blood clot supporting gauze matrix, a coagulation initiator, clot formation inside the enclosure, and extraction and transfer by removing the closure.
Blister-shaped sealed blood-clotting mold enclosure with gauze matrix and coagulation initiator
A blister having a main body with a blister depression having a blister wall and a flat rim, sealed by a removable closure, wherein the enclosure comprises a blood clot supporting matrix with gauze held at peripheral portions between the rim and the closure and a central portion within the enclosure, and wherein the enclosure comprises a coagulation initiator.
Needle-pierceable wall or closure for blood injection into the enclosure
At least one of the blister wall and closure is pierceable by needle, and the introducing comprises piercing one of the blister wall or closure with a needle and injecting the blood therethrough into the sealed enclosure.
Clotting within the enclosure followed by removal of the closure and extraction with the matrix
Maintaining the blood within the enclosure for a time sufficient to permit clotting of the blood to thereby obtain a blood clot; removing the closure to open the enclosure; and extracting the blood clot from the enclosure with the matrix.
Transferable blood clot on gauze and fixing onto the wound
Introducing blood into the blister-shaped enclosure sealed by the removable closure, allowing the blood clot to form on the gauze to be transferable thereby onto the wound; maintaining for a time sufficient to permit clotting; removing the closure to open the enclosure; extracting the blood clot from the enclosure by removal of the blood clot with the gauze; and fixing the blood clot onto the wound.
Across the independent claims, the inventive coverage centers on creating a blood clot inside a blister-shaped, removable-closure sealed enclosure that contains a coagulation initiator and a gauze-based blood clot supporting matrix, enabling needle injection through a pierceable wall or closure, then opening the enclosure by removing the closure and extracting a clot complex on gauze for transfer and fixing onto the wound.
