FLUID WASTE COLLECTION AND DISPOSAL SYSTEM AND METHOD
A system and method for continuously aspirating and collecting fluid waste during a medical procedure without interruption for disposal of the collected fluid waste. The system includes a first reservoir in communication with a vacuum source which produces a negative pressure therein to draw the fluid waste from the patient using a suction hose connected thereto. A second reservoir is in communication with the first reservoir. A pump draws fluid from the first and second reservoirs while additional fluid waste continues to be drawn into the first reservoir through the fluid inlet.
1 . A system for continuously aspirating a fluid from a patient, comprising:
a first reservoir in communication with a vacuum source producing a negative pressure therein, said first reservoir having a fluid inlet through which the fluid from the patient is drawn therein by said negative pressure therein, said first reservoir further having a fluid outlet;
a second reservoir in communication with said first reservoir;
a pump in communication with said fluid outlet operable to draw fluid from said first and second reservoirs while additional fluid from the patient continues to be drawn into said first reservoir through said fluid inlet.
2 . The system of claim 1 wherein said pump is operatively responsive to sensors disposed to detect predefined high fluid level limits and low fluid level limits in said second reservoir.
3 . The system of claim 1 wherein said pump is a metering pump.
4 . The system of claim 1 wherein said metering pump is a positive displacement pump.
5 . The system of claim 1 wherein said positive displacement pump is a peristaltic pump.
6 . The system of claim 1 further comprising a cleaning solution volume disposed for communication with said first reservoir.
7 . The system of claim 6 wherein said cleaning solution volume is substantially equal to but less than a said first and second reservoir volumes.
8 . The system of claim 6 wherein said cleaning solution volume is provided in a single-use disposable package.
9 . The system of claim 6 wherein said cleaning solution is a shelf-stable, pH-neutral, oxychlorine compound.
10 . The system of claim 8 wherein said cleaning solution is a shelf-stable, pH-neutral, oxychlorine compound.
11 . The system of claim 8 wherein said system further comprises a hanger disposed to removably support said single-use disposable package.
12 . The system of claim 1 wherein said first and second reservoirs and said pump are disposed within a secured housing; said housing have a window through which said aspirated fluid received within said first reservoir is viewable.
13 . The system of claim 12 further including lighting disposed to back-light said first reservoir within said housing such that the aspirated fluid is better viewed through said window.
14 . A method for continuously aspirating and collected fluid waste during a medical procedure without interruption for disposal of the collected fluid waste, said method comprising the steps of:
providing a first reservoir in communication with a vacuum source producing a negative pressure therein, said first reservoir having a fluid inlet and a fluid outlet;
providing a second reservoir in communication with said first reservoir;
providing a suction hose operably in communication with said fluid inlet at one end and with the fluid waste at a distal end, said negative pressure drawing the fluid waste through said suction hose and into said first reservoir;
pumping the fluid waste from said first and second reservoirs while additional fluid waste continues to be drawn into said first reservoir through said fluid inlet.
15 . The method of claim 14 wherein said step of pumping is initiated upon said fluid waste in said second reservoir reaching a predefined high fluid level.
16 . The method of claim 15 wherein said step of pumping is suspended upon said fluid waste in said second reservoir reaching a predefined low fluid level and until said fluid waste in said second reservoir again reaches a predefined high fluid level.
17 . The method of claim 14 further comprising the step of measuring fluid waste volume pumped using a metering pump.
18 . The method of claim 14 further comprising the step of measuring fluid waste volume pumped using a positive displacement pump.
19 . The method of claim 14 further comprising the step of measuring fluid waste volume pumped using a peristaltic pump.
20 . The method of claim 14 further comprising the step of cleaning after the medical procedure by drawing under said negative pressure a volume of cleaning solution through said fluid inlet.
21 . The method of claim 20 wherein said step of cleaning further comprises recirculating said volume of cleaning solution by pumping said volume of cleaning solution from said first and second reservoirs and back into said first reservoir through said fluid inlet.
22 . The method of claim 21 wherein said step of cleaning further comprises pumping said volume of cleaning solution from said first and second reservoirs.
23 . The method of claim 20 wherein said volume of cleaning solution is drawn from a single-use disposable package.
