Vacuum cup for delivery of agents during vacuum treatment

摘要

In various embodiments of the invention, the components can include a hemostatic vacuum cup which can utilize ancillary or self-contained vacuum generation, and a therapeutic agent which is supplied prior, simultaneously or subsequent to the application of a vacuum with the ultimate aim of slowing or arresting the flow of blood in a bodily tissue or organ. The invention relates to a hemostatic vacuum cup which can utilize ancillary or self-contained vacuum generation. The cup produces a hemostatic effect by the physical application of the device upon a traumatized tissue site and through the delivery of an agent, such as one that assists in hemostasis, antinociception, coagulation, sterilization, or other effective wound healing agents including antibiotics, antiseptics and antioxidants. The cup can be adapted to deliver the therapeutic agent, by methods integral to the vacuum cup. The therapeutic agent can be delivered in the form of a sponge, cellulose or other filter material.

主权项

1. A device for compressing a tissue surface comprising:
a vacuum cup including an outer perimeter adapted to attach to the tissue surface when a negative pressure is applied in the vacuum cup, a top and a wall including a plurality of parallel ridges extending lengthwise from the top of the cup toward the outer perimeter aligned perpendicular to the tissue surface, where the outer perimeter, the wall and the top define two or more cavities, where the plurality of ridges assist one or both deformation and collapse of the wall when the negative pressure is applied in the vacuum cup, where the outer perimeter is adapted to be positioned proximal to the tissue surface; and a vacuum source adapted to apply the negative pressure in the vacuum cup, where activation of the vacuum source evacuates air out of the vacuum cup such that when the outer perimeter is brought into contact with the tissue surface a negative pressure is generated in the vacuum cup which results in one or both the deformation and collapse of the wall and results in compression of the tissue surface.
