A method of manufacturing the antibacterial modified chitosan-based hemostatic material comprising: (i) preparing materials including: a modified chitosan ingredient and third different solutions including a solution containing polysaccharide, a solution containing dissolving solvent, and a solution containing nano silver; (ii) mixing the solutions prepared in step (i) to create a foundation mixture; (iii) loading the foundation mixture into a electrospinning device according to predetermined specifications to obtain the antibacterial modified chitosan-based hemostatic material in the form of nanofibers; and (iv) applying the antibacterial modified chitosan-based hemostatic material to a bleeding tissue on the surface of skin of a subject in need thereof to prevent bleeding and fluid exudation from the tissue, and promoting bacteriostatic and anti-inflammatory effects on the wound surface.
A portable, non-anchored support structure for positioning a retractable banner assembly and selectively deploying the assembly on a walking surface, comprises a base member and a stanchion supported by the base member in an upright position, wherein the stanchion orients the banner assembly in an upright position substantially normal to the walking surface.
A non-anchored, self-supporting screen assembly for selective placement by a user on a walking surface. The assembly includes a housing having a first end, a second end, and a sidewall extending therebetween and having an elongate opening. A base independently supports and disposes the housing in an upright position substantially normal to the walking surface during use. A rotatable rod is disposed within the housing and coupled to a trailing edge of a flexible screen. The flexible screen may be coupled to an external attachment point upon extension of the screen through the elongate opening and decoupled upon retraction. A spring is coupled to the rotatable rod to exert a force in a direction opposite a direction of extension of the flexible screen. The flexible screen of an adjacent assembly may be coupled to the assembly to form a screen system.
