Skin marking device
View Patent ↗A skin marking device is provided. The skin marking device has an outer frame that can be fitted over an ultrasound probe. The ultrasound probe can be used to identify a location for a needle or other medical device. Once the location is identified, the probe may be removed while keeping the frame in place. A skin-marking tool may then be fitted with/into the frame to mark the skin, thereby identifying the precise location for action.
1 . A skin-marking assembly comprising:
an outer frame sized to fit closely around an outer perimeter of an ultrasound probe;
a marking tool comprising top, bottom, left and right edges, the top, bottom, left edge, and right edge each being sized to slideably fit within an inner perimeter of the outer frame; and
the marking tool comprising a protrusion on a front side, the protrusion sized and configured to form an indent in a skin of a patient;
wherein the marking tool has a cross shape with a horizontal set of arms defining the left edge and right edge, and a vertical set of arms defining the top edge and bottom edge;
the outer frame further comprising two recessed slots formed by the inner perimeter of the outer frame and each of the two slots recessed from the inner perimeter, the two recessed slots sized and shaped such that either the horizontal set of arms or the vertical set of arms fit into the recessed slots.
2 . The skin-marking assembly of claim 1 wherein the marking tool further comprising a second protrusion on a rear side, the second protrusion having a same size and configuration as the protrusion on the front side.
3 . The skin-marking assembly of claim 2 wherein the protrusion of the marking tool comprises a central opening, and wherein the central opening extends from the front side of the marking tool to the rear side of the marking tool through the second protrusion, forming a continuous opening between the protrusion and second protrusion.
4 . The skin-marking assembly of claim 1 wherein the protrusion of the marking tool comprises a central opening.
5 . The skin-marking assembly of claim 4 wherein the central opening extends from the front side of the marking tool to a rear side of the marking tool.
6 . The skin-marking assembly of claim 1 wherein the outer frame has a rectangular shape and defines an opening through which the ultrasound probe may fit.
7 . A skin-marking assembly comprising:
an outer frame sized to fit closely around an outer perimeter of an ultrasound probe;
a marking tool comprising top, bottom, left and right edges, the top, bottom, left edge, and right edge each being sized to slideably fit within an inner perimeter of the outer frame; and
the marking tool comprising a protrusion on a front side, the protrusion defining an open shape such that a central opening is defined at a front of the protrusion;
wherein the marking tool has a cross shape with a horizontal set of arms defining the left edge and right edge, and a vertical set of arms defining the top edge and bottom edge;
the outer frame further comprising two recessed slots formed by the inner perimeter of the outer frame and each of the two slots recessed from the inner perimeter, the two recessed slots sized and shaped such that either the horizontal set of arms or the vertical set of arms fit into the recessed slots.
8 . The skin-marking assembly of claim 7 wherein the marking tool further comprising a second protrusion on a rear side, the second protrusion having a same size and configuration as the protrusion on the front side.
9 . The skin-marking assembly of claim 7 wherein the central opening extends from the front side of the marking tool to a rear side of the marking tool.
10 . The skin-marking assembly of claim 7 wherein the outer frame has a rectangular shape and defines an opening through which the ultrasound probe may fit.
