Abstract
A medical suction apparatus may include a wand having a proximal end and a distal end. The apparatus may further include a lumen defined within the wand, the lumen configured to couple to a suction source. The apparatus may also include a mouth defined at the distal end of the wand and placing the lumen in communication with an exterior of the wand, where the mouth has an upper edge and a lower edge, where the mouth is elongated horizontally between the upper edge and the lower edge, and where at least the upper edge or the lower edge is beveled to enable scraping of a surface.
Claims16
A medical suction apparatus comprising:
- a wand having a proximal end and a distal end;
- a lumen defined within the wand, the lumen configured to couple to a suction source;
- a mouth defined within a single integral wall of a single tube at the distal end of the wand and placing the lumen in communication with an exterior of the wand, wherein the mouth has an upper edge at the distal end of the wand and a lower edge closer to the proximal end than the distal end, wherein the upper edge includes a backward facing scraping edge to enable scraping of biological debris from a surface of soft biological tissue without harming the soft biological tissue when the wand is pulled in a backward direction, and wherein the lower edge includes a forward facing scraping edge to enable scraping of biological debris from a surface of soft biological tissue without harming the soft biological tissue when the wand is pushed in a forward direction.
A method for applying medical suction comprising:
- applying suction to a lumen defined within a wand, the wand having a proximal end and a distal end, the wand further having mouth having a first edge defined at the distal end of the wand and a second edge closer to the proximal end than the distal end, wherein the first edge includes a backward facing scraping edge, wherein the second edge includes a forward facing scraping edge and, wherein where the mouth places the lumen in communication with an exterior of the wand, wherein the first edge and the second edge enable scraping of biological debris from a surface of soft biological tissue without harming the soft biological tissue;
- scraping the biological debris from the surface of the biological tissue with the first edge of the mouth when the wand is tilted to an angle that places the first edge of the mouth in contact with the biological surface while the second edge of the mouth is not in contact with the biological surface and the wand is pulled in a backward direction;
- scraping the biological debris from the surface of the biological tissue with the second edge of the mouth when the wand is tilted to an angle that places the second edge of the mouth in contact with the biological surface while the first edge of the mouth is not in contact with the biological surface and the wand is pushed in a forward direction;
- and
- receiving the biological debris through the lumen.
2 more elements
A medical suction device comprising:
- a wand having a proximal end and a distal end;
- a lumen defined within the wand, the lumen configured to couple to a suction source;
- a mouth defined in the wand and placing the lumen in communication with an exterior of the wand, wherein the lumen curves downward at the distal end of the wand, wherein the mouth is at an obtuse angle relative to an outer surface of the wand, and wherein the mouth includes a backward facing scraping edge to enable scraping of biological debris from a surface of soft biological tissue without harming the soft biological tissue when the wand is pulled in a backward direction, and wherein the mouth includes a forward facing scraping edge to enable scraping of biological debris from a surface of soft biological tissue without harming the soft biological tissue when the wand is pushed in a forward direction.
