Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The nitric oxide source layer may include a nitrite salt. Nitrite ions of the nitric oxide source layer may react with the acidic groups of the activating layer to generate nitric oxide. The activating layer may include a window at the center, and a central absorbent material may be positioned at the window. Various separating layers may also be incorporated into the dressing to control the interaction between activating layer and nitric oxide source layer.

There are provided herein bioadhesive compositions which include at least one catechol derivatives, such as, caffeic acid derivatives, and at least one synthetic thermoplastic polymer, wherein exposure to heat causes the bioadhesive composition to transform into a non-solid state and to cohesively adhere to a biological tissue upon subsequent cooling. Further provided are methods of making the compositions and uses thereof in repairing tissue damage, such as, for example, in hernia repair surgeries.

A skin-friendly absorbent structure providing oxygen, comprising a absorbing layer and skin-friendly and oxygen-providing units, the skin-friendly and oxygen-providing unit being evenly dispersed in partial or entire scope of the absorbing layer wherein the skin-friendly and oxygen-providing unit comprises oxygen providing units and pH regulating units; and the pH of the skin-friendly absorbent structure is between 4 and 7 after absorbing liquids.

A blood coagulant assembly includes a blood coagulant device adapted to be insertable into a nostril of a patient to stop a nose bleed. The blood coagulant device is mounted within a blood coagulant device container which has a top container section and a lower container section secured to each other in a releasable manner. The blood coagulant device is mounted in a fixed position within the blood coagulant device container prior to its removal from the blood coagulant container. The blood coagulant device has a rigid handle configured with a handle lower section and a handle upper section contoured with a channel passing through both the lower and upper handle sections. A blood coagulant mechanism is secured to an outer surface of the handle upper section and a to a ledge section of the handle member which extends radially at a joint location of the handle's lower and upper sections.
