Abstract
A device and method for collecting distension media or other fluids discharged during surgical procedures is shown. Also shown is a method for reducing the risk of hyponatremia. The apparatus makes it practical to determine the amount of distension media retained by a patient during hysteroscopic or other surgical procedures, particularly procedures using non-isotonic distension media during monopolar electrosurgery. The apparatus and methods are also useful during a variety of laparoscopic, obstetric, cardiovascular, liposuction, plastic, orthopedic, restorative, and other procedures.
Claims20
A disposable surgical and diagnostic fluid control island placeable on an operating room floor for selectably collecting, retaining and draining fluids received from patients during surgery comprising:
- a. a generally broad, shallow, impermeable vessel-forming base having
- i. a peripherally floor-contacting, undersurface portion and an upper surface portion with a raised center,
- ii. a multiplicity of sloping channels extending downward from the raised center toward a lower peripheral channel at the base of a generally vertical peripheral wall disposed between a fluid-contacting central portion and a distal peripheral skirt,
- iii. a generally beveled upper skirt surface extending between the top of the generally vertical peripheral wall and a distal base edge proximate the floor,
- b. a generally non-absorbent splash pad disposed within the fluid-contacting central portion and supported by ribs above the sloping channels and extending proximal to the raised peripheral wall, and
- c. means for connecting fluid-removing suction tubing proximate the lower peripheral channel.
A method for selectably collecting, retaining and draining fluids received from patients during surgery in a disposable surgical and diagnostic fluid control island placeable on an operating room floor comprising the steps of:
- a. placing onto an operating room floor a generally broad, shallow, impermeable vessel-forming base having
- i. a generally horizontal, peripherally floor-contacting, undersurface portion,
- ii. an upper surface portion having a raised center having sloping channels extending downwardly from the center toward a lower peripheral channel at the base of a generally vertical peripheral wall disposed between a fluid-contacting central portion and a radially outwardly disposed skirt,
- iii. a generally beveled upper skirt surface extending between the top of the generally vertical peripheral wall and a distal base edge proximate the floor,
- b. attaching a generally non-absorbent splash pad disposed within the fluid-contacting central portion of the base and supporting the splash pad above the sloping fluid conducting channels that extend proximal to the raised peripheral wall, and
- c. connecting fluid-removing suction tubing to the base proximate the lower peripheral channel.
A method of making a disposable surgical and diagnostic fluid control island placeable on an operating room floor for selectably collecting, retaining and draining fluids received from patients during surgery comprising the steps of:
- a. forming a generally broad, shallow, impermeable vessel-forming base having
- i. a generally horizontal, peripherally floor-contacting, undersurface portion,
- ii. an upper surface portion with a raised center having sloping channels that extend from the raised center downwardly toward a lower peripheral channel at the base of a generally vertical peripheral wall disposed between a fluid-contacting central portion and a peripheral skirt,
- iii. a generally beveled upper skirt surface extending between the top of the generally vertical peripheral wall and a distal base edge proximate the floor,
- b. affixing to the base raised center a generally non-absorbent splash pad disposed within the fluid-contacting central portion and supporting the splash pad on ribs disposed above the radial sloping channels and extending proximal to the raised peripheral wall, and
- c. connecting fluid-removing suction tubing proximate the lower peripheral channel.
