Claims12
A clot preparation device comprising:
- a base having a topmost surface and a bottom surface configured to contact a horizontal surface, the topmost surface being sloped from a first edge of the base toward a second edge of the base with respect to the bottom surface;
- a work surface supported on the topmost surface of the base, the work surface comprising:
- an upper working area;
- a continuous channel extending around an outer periphery of the upper working area, at least a portion of the continuous channel extending lower than an adjacent part of the upper working area and an adjacent perimeter extending around an outer periphery of the continuous channel so that fluid placed on the upper working area will drain into the continuous channel under force of gravity when the bottom surface is placed on the horizontal surface;
- and
- at least one drainage opening defined through the work surface.
