Blood coagulation inducing polymer hydrogel

Номер: US20120009242A1

The present application is drawn to a synthetic, polymer hydrogel-based material, which is able to actively induce the body's natural hemostatic coagulation process in blood or acellular plasma. The present invention provides the development of a primary amine containing polymer hydrogel capable of inducing blood coagulation and delivering therapeutics for hemostatic or wound care applications, and a method of forming such a primary amine containing polymer hydrogel capable of inducing the blood coagulation process. The primary amine containing polymer hydrogel is able to achieve the same end result as biological-based hemostatics, without the innate risk of disease transmission or immunological response, and at a fraction of the price. Furthermore, due to its inherent hydrogel-based design the material has the capability of arresting blood loss while simultaneously delivering therapeutics in a controlled manner, potentially revolutionizing the way in which wounds are treated.

However, the precise mode of action of silver salts in killing microbes is yet to be established. It is known that silver salts bind with particular avidity to DNA and RNA. Silver salts also bind with particular strength to a variety of organic molecules such as: carboxylic acids, thiols, phenols, amines, phosphates and halogenated compounds. Following binding to proteins, those with enzymic activity are usually deactivated. The oxidative-reductive powers of silver and silver salts must also be reckoned with.It is known to use metallic silver as an antimicrobial, whether in the form of thin films, nanoparticles or colloidal silver.

Multi-Layer Wound Care Device Having Absorption and Fluid Transfer Properties

Номер: US20200000640A1
Принадлежит:

This disclosure relates to a multi-layer wound care device having absorption and fluid transfer properties. The wound care device contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device provides improved absorption properties. 1. A wound care device comprising:a first layer of fabric having a wound contact surface and a wound fluid reservoir surface, wherein the first layer of fabric contains lyocell fibers;a first hotmelt adhesive; anda second layer of fabric;wherein the first hotmelt adhesive is disposed between the first layer of fabric and the second layer of fabric; andwherein the first hotmelt adhesive is disposed on the wound fluid reservoir surface of the first layer of fabric; andwherein the wound care device transports wound fluid uni-directionally from the wound contact surface to the wound fluid reservoir surface upon exposure to a wound.2. The wound care device of claim 1 , wherein the first layer of fabric is knit fabric.3. The wound care device of claim 2 , wherein the knit fabric is circular knit fabric.4. The wound card device of claim 3 , wherein the circular knit fabric is a jersey knit fabric.5. The wound care device of claim 1 , wherein the first layer of fabric is comprised primarily of hydrophobic fibers and hydrophilic fibers.6. The wound care device of claim 5 , wherein the hydrophobic fibers are polyester fibers.7. The wound care device of claim 5 , wherein ...
