Abstract

A portable drain system having a subdermal drain and a container in fluid communication with the subdermal drain is disclosed. The subdermal drain is configured to drain fluid from a surgical site. The container provides a negative pressure to the subdermal drain. The container draws and receives the fluid. The container includes at least one sensor in which the at least one sensor is configured to detect at least one of fluid color, fluid volume in the container, and orientation of the container.

First claim

What is claimed is:

1. A portable surgical drain system, comprising:
a subdermal drain at a first end of the portable surgical drain system, the subdermal drain configured to drain fluid from a surgical site; and
a container at a second end of the portable surgical drain system, the container in fluid communication with the subdermal drain providing a negative pressure to the subdermal drain, the container including a cartridge having a vacuity to draw and receive the fluid into the cartridge and a drain hub, the cartridge removably coupled to the drain hub to form the container, wherein the container includes at least one sensor disposed on the drain hub proximate a wall of the cartridge in which the at least one sensor is configured to detect from outside the cartridge at least one of fluid color, fluid volume in the cartridge, and orientation of the container, wherein the detection of the fluid volume and fluid color are based on whether the container is detected in a selected orientation.

2. The portable surgical drain system of claim 1 wherein the at least one sensor includes an inertial motion sensor to detect orientation of the container.

3. The portable surgical drain system of claim 1 including a processing circuit configured to receive signals from the at least one sensor.

4. The portable surgical drain system of claim 3 wherein the sensor includes a volume sensor to detect fluid volume in the container and the processing circuit is configured to determine fluid flow from the volume sensor.

5. The portable surgical drain system of claim 1 wherein the subdermal drain includes a lubricious coating.

6. The portable surgical drain system of claim 5 wherein the subdermal drain includes a lubricious coating on an inside surface and an outside surface.

7. The portable surgical drain system of claim 1 wherein the subdermal drain includes antimicrobial agents.

8. The portable surgical drain system of claim 7 wherein the subdermal drain includes an antimicrobial coating.

9. The portable surgical drain of claim 1 wherein the subdermal drain includes a heparin coating.

10. The portable surgical drain of claim 1 wherein the subdermal drain includes a drug eluding outside surface.

11. The portable surgical drain of claim 10 wherein the drug includes at least one of an antibiotic and anti-inflammatory agent.

12. The portable surgical drain system of claim 1 wherein the subdermal drain is fluidically coupled to the container via tubing.

13. The portable surgical drain system of claim 1 wherein the container is a suction source.

14. The portable surgical drain system of claim 13 wherein the container is set at a prescribed pressure.

15. A portable surgical drain system, comprising:
a subdermal drain at a first end of the portable surgical drain system, the subdermal drain configured to drain fluid from a surgical site; and
a container at a second end of the portable surgical drain system, the container in fluid communication with the subdermal drain providing a negative pressure to the subdermal drain, the container including a cartridge having a vacuity to draw and receive the fluid into the cartridge and a drain hub, the cartridge removably coupled to the drain hub to form the container, wherein the container includes at least one sensor disposed on the drain hub proximate a wall of the cartridge in which the at least one sensor is configured to detect fluid color, fluid volume in the cartridge from outside the cartridge, and orientation of the container, wherein the detection of the fluid volume and fluid color are based on whether the container is detected in a selected orientation; wherein the drain includes a suction member in fluid communication with the container and an inflatable balloon isolated from fluid communication with the container.

16. The portable surgical drain system of claim 15 wherein the inflatable balloon is distal the suction member.

17. The portable surgical drain system of claim 15 having a separate lumen in fluid communication with the inflatable balloon, wherein the separate lumen is not in fluid communication with the container.

18. The portable surgical drain system of claim 15 having a valve to selectively open and close the separate lumen.

19. The portable surgical drain system of claim 18 wherein the balloon is configured to be selectively inflated within the patient to hold the drain within the surgical incision and further configured to be selectively subsequently deflated to remove the drain from the patient.

20. The portable surgical drain system of claim 15 wherein the drain includes a lubricious coating.

21. The portable surgical drain system of claim 20 wherein the drain includes a lubricious coating on an inside surface.

22. The portable surgical drain system of claim 20 wherein the drain includes antimicrobial agents.

23. The portable surgical drain of claim 22 wherein the drain includes a heparin coating.

24. A container for a portable surgical drain system to receive a fluid from a drain at a surgical site, the container comprising:
a drain hub having a side and a sensor, the side including a sensor window and the sensor being disposed proximate an interior of the side and the sensor window; and
a cartridge removably coupled to the drain hub in fluid communication with the drain, the cartridge having a vacuity to draw and receive the fluid from the surgical site;
the cartridge disposed against an exterior of the side and the sensor window wherein the sensor includes an array of photodiodes on the drain hub to detect fluid volume and fluid color in the cartridge, wherein the detection of fluid volume and fluid color are based on whether the container is detected in a selected orientation.

25. The container of claim 24 wherein the drain hub includes a processing circuit configured to receive signals from the sensor.

26. The container of claim 25 wherein the drain hub includes a communications module operably couplable to a computing device via a wireless-network to exchange computer data between the processing circuit and the computing device.

27. The container of claim 25 wherein the drain hub includes a plurality of sensors including an inertial motion sensor and the volume sensor.

28. The container of claim 27 wherein the array of photodiodes are configured to detect fluid volume in the cartridge during a selected orientation of the cartridge and the processing circuit is configured to receive a signal from the volume sensor when the container is in the selected orientation as determined from a signal from the inertial motion sensor.

29. The container of claim 28 wherein the volume sensor includes another array of photodiodes configured to detect fluid volume in the cartridge during another selected orientation of the cartridge and the processing circuit is configured to receive a signal from the volume sensor when the container is in the another selected orientation as determined from a signal from the inertial motion sensor.

30. The container of claim 25 wherein the processing circuit is configured to provide an alert when the cartridge is filled to a selected volume of fluid.

31. The container of claim 24 wherein the cartridge is set at a prescribed pressure.

32. The container of claim 24 wherein the drain hub
