Operating room body gas evacuation system

Abstract

A operating room body gas evacuation system and method for the removal of carbon monoxide generated during a surgical procedure with the system including a trocar having an outlet connected to a carbon monoxide removal material to remove the carbon monoxide generated during the surgical procedure and if the air is humidified a desiccant to remove water vapor before flowing the body gas through the carbon monoxide removal material.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is cross sectional view of an inline device for removing carbon monoxide;

FIG. 2 is a side view of a trocar system having an evacuation tube containing a carbon monoxide removal material;

FIG. 3 is a cross sectional view of a dual filter device for removal of contaminants in a carbon medium and for removal of carbon monoxide downstream of the carbon medium;

FIG. 4 is a cross sectional view of an operating room body gas evacuation system with a desiccant and odor removal material located in the evacuation line and a carbon monoxide removal device secured to the evacuation line to remove carbon monoxide from the gas flowing therethrough;

FIG. 5 is a cross sectional view of a replaceable evacuation line for an operating room body gas evacuation system with the evacuation line including an odor removing material proximate a carbon monoxide removing material so that gas flowing though the tubing removes particulate matter as well as carbon monoxide; and

FIG. 6 shows an operating room partially in schematic having an operating room body gas evacuation system of FIG. 4 removing unwanted gas and particles before discharging the gas into the operating room.

Claims

1. A operating room body gas evacuation system for use during and after surgical procedures using laser cautery, electrosurgical procedures or the like which can generate harmful body byproducts comprising: a trocar;a fluid evacuation line coupled to the trocar; anda carbon monoxide removable material located in the evacuation line for removal of a carbon monoxide gas before the body gas is discharged to an atmosphere of the operating room.

2. The operating room body gas evacuation system of claim 1 including a particulate filter in series with the carbon monoxide removable material.

3. The operating room body gas evacuation system of claim 1 including an attachable housing containing the carbon monoxide removal material with the housing containing an inlet for receiving the body gas and an outlet for discharging the body gas while the carbon monoxide is retained therein by the carbon monoxide removable material.

4. The operating room body gas evacuation system of claim 1 wherein the evacuation line comprises a tube coupled to the trocar with the tube containing the carbon monoxide removable material and a desiccant.

5. The operating room body gas evacuation system of claim 4 including a particulate filter connected thereto to remove particles in the evacuated body gas and a vacuum source for drawing the body gas through the system.

6. The operating room body gas evacuation system of claim 5 including a bed of activated carbon in the system.

7. The operating room body gas evacuation system of claim 1 including a desiccant located in the body gas evacuation system with the desiccant located upstream of the carbon removable material to thereby remove moisture from the body gas before the body gas enters the carbon monoxide removable material.

8. An on-the-go in room operating room body gas evacuation system comprising: a desiccant;a particulate filter medium;a carbon monoxide removing material; anda trocar in fluid communication with the desiccant, the particulate filter medium and the carbon monoxide removal material to enable a body gas from a body cavity to be discharged through the desiccant, the particulate filter medium and the carbon monoxide removing material to thereby remove harmful particles as well as carbon monoxide gas from the body gas flowing therethrough.

9. The on-the-go operating room body gas evacuation system of claim 8 wherein the pressure in the body cavity is sufficient to discharge the gas to the atmosphere through the desiccant, the particulate filter medium and the carbon monoxide removing material.

10. The on-the-go operating room body gas evacuation system of claim 8 including an odor removing material contained in a fluid conduit in the system.

11. The on-the-go operating room body gas evacuation system of claim 10 wherein the odor removing material is activated carbon.

12. The on-the-go operating room body gas evacuation system of claim 8 including a carbon dioxide removing material.

13. The on-the-go operating room body gas evacuation system of claim 8 wherein the desiccant for the removal of moisture is located upstream of the carbon monoxide removing material.

14. The on-the-go operating room body gas evacuation system of claim 8 including a carbon monoxide monitor for providing a visual or audible alarm when the carbon monoxide in an operating room exceeds a preset level.

15. The on-the-go operating room body gas evacuation system of claim 8 wherein the carbon monoxide removal material and the desiccant are located in a housing that can be quickly coupled into the operating room body gas evacuation system.

16. The method of removing body gas from a patient during surgery comprising: placing an evacuation tube in the body cavity;performing a surgical process in the body cavity that generates a body gas containing a carbon monoxide gas; andflowing the body gas from the body cavity through a housing containing a carbon monoxide removal material to thereby retain the carbon monoxide gas in the housing before discharging the body gas into an operating room.

17. The method of claim 16 including the step of first flowing the body gas through a desiccant to remove moisture from the body gas before removing the carbon monoxide gas from the body gas.

18. The method of claim 17 including flowing the body gas through a filter to remove particles from the body gas before discharging the body gas into an operating room.

19. The method of claim 18 including monitoring the level of carbon monoxide in the operating room with an in room carbon monoxide detector.

20. The method of claim 19 including replacing the housing with a further housing containing a further carbon monoxide removable material if the carbon monoxide monitor indicates the carbon monoxide level has exceeded a harmful level.

21. The method of claim 18 wherein the step of placing an evacuation tubes comprises placing a trocar with an evacuation port in the body cavity.
