FIG. 1A is a schematic diagram of one embodiment of a surgical drain in use having at least one sensor; FIG. 1B is a schematic diagram depicting one embodiment of a surgical drain; FIG. 1C is a schematic diagram of one embodiment of the surgical drain in use having a plurality of sensors.
FIGS. 2A & B are each schematic diagrams each of one embodiment of the invention.
FIGS. 3A-F are schematic diagrams depicting views of embodiments of the surgical drain according to the invention. FIGS. 3A-F are bottom views of embodiments of a surgical drain; FIGS. 3D & E are end views of embodiments of a surgical drain.
FIG. 1A is a schematic diagram depicting one embodiment of a surgical drain in use having at least one sensor. As shown in FIG. 1A, the device may include a surgical drain 10 configured for implantation within the patient's body proximate to a tissue and/or organ 100 of interest having at least one sensor or receiver 12.
The surgical drain 10 may include one or a plurality of sensors 12 in communication with a monitor 14, such as via a data cable 16. The monitor 14 may also include a display 18 configured to depict information obtained from the sensor 12. The surgical drain 10 may be in communication with a tube 40 having a conduit lumen 42, such that the fluids passing from the body in the drain lumen 32 may be transported out of the body 102 via the conduit lumen 42. The tube 40 may be formed integrally or as separate piece attached to the surgical drain 10.
FIG. 1B is a schematic diagram depicting one embodiment of a surgical drain 10. As shown in FIG. 1B, the surgical drain 10 may have a drain length 20, extending from the drain distal end 22 to the drain proximal end 24. The surgical drain 10 may have an outer surface 26 and a drain inner surface 28 and a drain wall 30 extending from the drain outer surface 26 to the drain inner surface 28. The drain wall 30 may be in any cross-sectional shape, such as rectangular, round, oval. The surgical drain 10 may include a drain lumen 32 extending the drain length 20, and the drain lumen 32 may be open or closed at the drain distal end 22. The surgical drain 10 may include at least one or a plurality of drain holes 34 extending through at least one location on the drain wall 30. The surgical drain 10 may include approximately a drain upper surface 36, and a drain lower surface 38, and may include drain holes 34 on the drain upper surface 36 and/or lower surface 38.
