Definitions
- the present invention relates to the art of handling biological fluids. It finds particular application in conjunction with the collection, treatment, and disposal of fluid wastes in operating rooms, patient care rooms, emergency care units, and other medical facilities and will be described with particular reference thereto.
- the receiving receptacle often varied with the nature and volume of the fluids to be collected.
- Typical fluids have included blood, urine, mucous, and other body discharges.
- a saline solution or other rinse and lubricating fluid was selectively introduced into the surgical site. The fluid was drawn off from time to time, removing with it surgical scraps, any blood, and other body fluids that may have entered into the surgical site.
- Simple bags and pouches could be hung from the surgical table or placed at other convenient locations within the room in which the medical procedure was performed.
- Flexible tubing typically interconnected the bag with the region of the patient from which the fluid wastes were collected.
- Such bags or pouches had several drawbacks.
- Such bags or pouches were typically emptied manually, creating the opportunity for direct human contact with potentially infected wastes.
- Second, difficulties could arise if the volume of drained fluid exceeded the capacity of the bag. Not only would the fluid not drain, but fluid in the bag and the connecting line would be under a positive pressure attributable to the fluid held in the line and resiliency of the bag or pouch.
- the present invention contemplates a new and improved biological fluid collection, handling, and disposal system which overcomes the above-referenced disadvantages and others.
- an apparatus for handling biological and medical waste fluid is provided.
- At least one inlet fitting is interconnectable with a flexible tube that is connected with a source of the waste fluid.
- a collection vessel is connected with the inlet fitting such that received waste fluid flows into the collection vessel.
- a drain line and a drain valve are connected with the collection vessel for selectively draining it.
- a cleaning fluid line is connected with a source of rinse and disinfectant liquids.
- the cleaning fluid line has a fitting that is selectively connected with the inlet fitting for selectively supplying the rinse and disinfectant liquids to the inlet fitting, through the inlet fitting to the collection vessel.
- a vent line is connectable between the collection vessel and one of a vacuum source and the atmosphere for selectively venting exhaust gases displaced as the waste fluid is received.
- the apparatus is characterized by a level sensor for sensing a level of the waste fluid in the collection vessel.
- a vent valve in the vent line selectively blocks the exhaust gases from venting.
- An automatic shut-off circuit is connected with the level sensor and the vent valve for responding to the level sensor sensing that the fluid level in the vessel is approaching a preselected capacity by causing the vent valve to block the exhaust gases from venting.
- the inlet fitting has a male portion over which the flexible tube is frictionally received.
- the cleaning fluid line fitting includes a bell which interconnects to the inlet fitting spaced from the male portion.
- a disinfectant liquid circulation region is provided between the bell and the male portion so that the disinfectant liquid passes over both interior and exterior portions of the inlet fitting.
- a rinse liquid inlet is connected with the cleaning fluid line for receiving the rinse liquid.
- a disinfectant reservoir holds the disinfectant liquid.
- An entraining means connected with the cleaning fluid line and the disinfectant reservoir selectively entrains the disinfectant liquid in the rinse liquid.
- a means for charging into the reservoir a predetermined dose of powdered reagents which intermix with the rinse liquid to form the disinfectant liquid.
- a means is provided for circulating the rinse liquid through the reservoir to promote intermixing with the powdered reagents.
- a method of handling medical and biological waste fluid is provided.
- the waste fluid is received from fluid lines connected with a source of the waste fluid through an inlet fitting and are collected a collection vessel.
- exhaust gases and vapors are discharged through a vent line.
- the collection vessel is interconnected to the inlet fitting by interconnecting tubing.
- the waste fluid is discharged through a drain outlet.
- rinse water is passed through the inlet fitting, the interconnecting tubing, and the collection vessel to rinse waste fluid residue, after which the drain outlet is closed.
- a level of waste fluid in the collection vessel is monitored.
- a warning is provided to an attendant and the vent line is closed to prevent the discharge of the exhaust gases and vapors.
- the closing of the vent line creates a backpressure in the vessel which inhibits the receipt of further fluid waste.
- One advantage of the present invention is that it is fully automatic. The potential for direct contact between a human patient or operator and the collected fluids is minimized.
- Another advantage of the present invention is that it ensures the disinfection is conducted with a disinfectant solution of a predetermined concentration.
- Another advantage of the present invention is that it minimizes the potential for fluid in flexible feed lines from spurting onto the patient, attendant, or wound site. Another advantage of the present invention resides in the automatic decontamination of the apparatus which again minimizes the opportunity for human contact with disposed fluids.
- Another advantage of the present invention resides in improved safety and warning features which inhibit misuse of the equipment.
- the invention may take form in various components and arrangements of components, and in various steps and arrangements of steps.
- the drawings are only for purposes of illustrating a preferred embodiment and are not to be construed as limiting the invention.
- FIGURE 1 is a diagrammatic illustration of a biological and medical fluid waste collection, handling, and discharge system in accordance with the present invention
- FIGURE 2 is a diagrammatic illustration of an electronic control circuit in accordance with the present invention for the system of FIGURE 1;
- FIGURE 3 is a diagrammatic illustration of an assembly of the system of FIGURE 1 for opening disinfectant cartridges
- FIGURE 4 is a detailed sectional view of a self-sterilizing fluid coupling assembly in accordance with the present invention in a detached configuration; and, FIGURE 5 is a detailed sectional view of the self-sterilizing fluid coupling of FIGURE 4 in a connected configuration.
- a common housing holds a first fluid waste receiving assembly 10 and a second fluid waste receiving assembly 10'.
- Fluid waste receiving assemblies 10 and 10' are significantly analogous that a detailed description will be made to the parts of assembly 10 and the description will be understood as describing the assembly 10' as well.
- Like parts in assembly 10' are denoted with the same reference numeral as in assembly 10 but followed by a prime (') .
- a pair of inlet fittings 12, 14 are rigidly mounted to a housing and configured to be received frictionally in flexible tubing which is connected with the patient or other source of fluid waste.
- the fittings are connected through inlet tubes 16, 18 with a fluid receiving vessel 20. More specifically, the fluid receiving vessel 20 has multiple chambers including a first chamber 22 and a second chamber 24 which are interconnected by a fluid level equalization path 26 adjacent a lowermost end of each.
- a pressure equalization passage 28 allows the fluid level in the first and second chambers to equalize.
- the inlet tubes 16, 18 have discharge ends disposed in an uppermost region of the first chamber 22. The fluid discharged from the inlet tubes into the first chamber 22 tends to be turbulent and may have froth or foam on its upper surface.
- the fluid connection passage 26 allows the least turbulent portion of the fluid at the bottom of the first chamber 22 to flow into the second chamber 24.
- a valve 30 interconnects a line 32 through a filter 34 with the upper region of the second chamber 24.
- Line 32 is connected to a vacuum, such as the in-wall vacuum system found in most hospitals, if the fluid wastes are to be drawn in under a vacuum or connects with atmosphere if the fluid wastes are to be drained by gravity flow.
- a level sensor such as a float switch 36 senses the level of the fluid in the vessel 20.
- the level sensor 36 sends signals to an electronic control circuitry 40 indicative of the level of fluids in the vessel 20. Before the level of the fluid reaches the lowermost surface of the inlet tube 16, 18, the collection of fluid wastes is terminated.
- an electronic control 40 terminates venting/suction when the vessel 20 becomes filled. More specifically, the output of the level sensor 36 is conveyed to an analog-to-digital converter 42 which digitizes the level signal.
- a digital display 44 provides the operator with a digital display of capacity remaining. Alternately, the digital display 44 can provide an indication of the volume of fluid collected.
- the received fluid and level information is stored in a history memory 46.
- a microprocessor controller 50 includes a comparator 52 which compares the digital fluid level signal with a capacity from a capacity memory 54. When the full capacity is reached, the comparator starts an off or termination sequence processor 56.
- the off sequence processor 56 actuates an audio alarm 58 and a visual alarm 60.
- a predetermined time later e.g., 30 seconds, as determined by a timer 62, or a predetermined fluid level increase later as determined from the digital level signal from the level sensor 36, the off sequence processor closes valve 30. If the system is connected with a vacuum source, this terminates the draw of the vacuum source. If connected to atmosphere for gravity drain, this closes the atmospheric vent to create backpressure terminating the ingress of fluid wastes.
- the off sequence processor communicates the level, time, and other termination sequence information to the history memory 46.
- a manually operated valve 64 is selectively operated by the attendant after the inlet ends of the flexible tubing have been disconnected from the source of the fluid waste.
- Opening valve 64 again vents the vessel 20 to atmosphere, allowing any residual pressure in the lines and the inlet tubes 16, 18 to be safely relieved to atmosphere.
- the inlet fittings 22 and 12 are physically positioned at a higher elevation than the top of the vessel 20 such that gravity causes any remaining fluids therein to flow into the vessel 20.
- the flexible waste tubes When the flexible waste tubes are disconnected from the collection system 10, they may be reconnected immediately to collection system 10' for the collection of further fluids, unless system 10' is already connected to other sources of fluid waste or is filled to capacity.
- the collection systems 10, 10' are housed in a common wheeled housing. After the vessels are filled, the housing is wheeled to a drain into which the fluids in the vessels 20 and 20' are drained.
- the drain can be a standard sanitary or sewer drain.
- the waste biological fluids present a biological load to the sewage treatment station which is analogous to the load traditionally sent into sewage treatment stations.
- an attendant connects a drain hose outlet 70 to a drain hose which direct effluent to a drain.
- a drain hose sensor switch 72 checks the presence of the drain hose to assure that a drain valve 74 will not be opened in its absence.
- the attendant further connects self-disinfecting over-fittings 80, 82 with the inlet fittings 12, 14.
- the fittings 80, 82 are connected to flexible fluid supply tubing lengths which extend out of the housing.
- a water inlet fitting 84 is interconnected with a source of water.
- the system is connected directly with the plumbing system of the building.
- a pressure regulator 86 limits the pressure of the incoming water.
- a flow monitor 88 monitors the flow rate of the received water.
- the flow monitor 88 produces a digital output signal indicative of the flow rate, which output signal is conveyed to the history memory 46 and to a low flow rate warning circuit 90.
- the flow rate warning circuit compares the flow rate with an appropriate flow rate for the current cycle as supplied by the history memory 46. When an insufficient fluid flow rate is provided, the flow rate sensor triggers an alarm 92 to alert the attendant that there is insufficient water flow for proper operation.
- the housing is mounted to a wall in the medical facility and the outlet is permanently connected with sanitary plumbing of the building.
- a drain outlet 70 and a drain hose sensor switch 72 are not strictly necessary for operation but are preferably still retained for such times as when maintenance dictates removal of the entire assembly from the wall mounting.
- the off sequence processor 56 automatically opens the drain valve 74 when the level sensor 36 senses that the fluid level in the vessel 20 is at or is approaching capacity.
- a safety override circuit 102 queries the history memory 46 to determine whether the system is in an appropriate state to be drained. If the history memory 46 is in the appropriate state to be drained, then the safety override allows the drain valve 74 to be opened. For safety, the drain hose presence switch 72 detects that a drain hose has been connected to the unit. That information is communicated to the history memory 46. If the drain hose is not connected, the safety override 102 prevents the valve 74 from opening. Analogously, if the drain hose is connected, the safety override 102 allows the drain valve 74 to open and vessel 20 drains.
- a cleaning sequence processor 104 actuates a pump 106, opens a fluid inlet valve 108, and opens fluid inlet valves 110, 112 concurrently or sequentially.
- a fluid inlet valve 108 opens fluid inlet valves 110, 112 concurrently or sequentially.
- fittings 12 and 14 may be cleaned concurrently or sequentially.
- vessels 20 and 20' may be cleaned either concurrently or sequentially.
- the cleaning sequence processor maintains the drain valve 74 in an open state so that the rinse water can drain and opens a valve 114 or the valve 30 to vent the vessel to atmosphere.
- a disinfectant supply valve 116 is opened.
- the disinfectant supply valve supplies a disinfectant concentrate from a disinfectant concentrate supply 118 to a venturi block 120.
- the venturi which is preferably integral with the supply valve 116, introduces a metered concentration of the disinfectant into water flowing into the system.
- the disinfectant supply system 118 includes an inlet valve 122 is opened until the disinfectant supply system is filled to a preselected level.
- a reservoir 124 receives a unit dose of a powdered reagent, preferably from a single use cup or cartridge 126. As explained below in greater detail in conjunction with FIGURE 3, the cartridge 126 is opened, releasing the powdered material.
- a pump 128 recirculates the received water through the chamber 124 until the powdered reagents are dissolved and react to form a disinfectant concentrate.
- a vent valve 130 is also opened to enable the venturi 120 to draw the disinfectant concentrate into the water supply stream.
- a disinfectant drain valve 132 is opened to drain any leftover disinfectant concentrate to the drain outlet 70. In this manner, a unit dose of new disinfectant is mixed for each disinfectant cycle.
- valves 108, 110, and 112 are closed as valve 140 is opened, such that the interior of the tank sections 22, 24 are flushed out by water through spray heads 142.
- valve 140 is closed and valves 108, 110, 112, and 116 are opened to supply disinfectant through the inlet fittings 12, 14.
- the valves 108, 110, and 112 are again closed and valve 140 is opened such that the disinfectant material is sprayed into the tank 20, disinfecting the walls of chambers 22, 24.
- An array of drain valves 144 and vent valve 146 are also opened to allow any disinfectant solution trapped in the fittings 12, 14 to drain. After a preselected duration, the drain valve 74 is closed, allowing disinfectant solution to pool in the bottom of the tank 20. After a further preselected duration keyed to place a preselected volume of disinfectant within the tank 20, the pump 106 is stopped and valves 116, 140 and 144 are closed. Thereafter, the drain valve 132 and a drain valve 148 are opened to allow extra disinfectant and fluid in the system to be drained to the drain outlet 70.
- a pressure switch 150 is connected adjacent an output end of the pump 106 and with the memory history 46.
- An over/under pressure sensor 152 compares the pressure from the pressure sensor 150 with acceptable operating pressures for the pump. In an over/under pressure situation, the pressure indicator switch through the memory history and the safety overrides terminates operation of the pump and alerts the attendant of a malfunction.
- a mechanical indicator of fluid level in the vessel 20 is provided. More specifically, a float 160 is interconnected with a float rod 162. The float rod 162 extends through an at least partially transparent sealed tube 164 at the top of the vessel 20. The level of the float rod 162 in the tube 164 is indicative of the level to which the vessel 20 is filled.
- the disinfectant supply 118 includes a slide drawer or tray 166 that defines a cup or cartridge receiving aperture therein for receiving the cup or cartridge 26.
- the cassette 126 is a two compartment cup constructed of a thin polyethylene or other plastic material.
- An outer cup 168a receives a more tapered inner cup 168b therein.
- the inner and outer cups meet at the base in a truss-like configuration to inhibit collapsing of the cup.
- the cup defines two chambers, an outer chamber 170a which contains one component in powdered form and an inner chamber 170b which contains another component in powdered form.
- the powdered components are reagents which interact in the presence of water to form a strong oxidant, such as peracetic acid, lithium hypochlorite, or other materials having anti-microbial activity.
- the drawer with the received cup is slid inward with a spring-biased plate 172, urging the cup firmly downward against the drawer.
- a mechanical actuator assembly 174 selectively raises a mechanical assembly 176 which defines the mixing chamber 124 therein. After the cup and drawer are slid in, the mechanical actuator 174 raises the mechanical assembly 176 until it presses firmly around the cup, defining a closed chamber.
- a cup cutting blade 180 is disposed in the chamber.
- the cutting blade has sharpened side edges 182 which initially engage peripheral edges of the cup, centering it and holding it in a centered configuration as the assembly 176 continues to raise. With further lifting of the assembly, the centering edges 182 cut into sides of the cup as a center peak 184 and intermediate peaks 18 pierce the bottom of the cup. With continued rising of the assembly 176, non-symmetric taper angles on the cutting edges of peaks 184 and 186 slice and rip open the inner and outer cups.
- the blade is supported on a tubular member 190 in fluid communication with the pump 128.
- the tubular member 190 includes a plurality of jets 192 which are aimed up into the inner and outer cups to flush all powdered reagents from the cup. Additional jets 194 assure that all powdered reagents which fall from the cup are flushed into the recirculating liquid and dissolved.
- a limit switch 196 senses the resistance as the blade engages the cup. If the cup is full, there is sufficient resistance to lift the plate 170 and engage the limit switch. If the cup was previously used, there is too little resistance to lift the plate. The failure to sense the resistance of cutting into a full cup is transmitted to the processor 50 which causes an appropriate alarm to be generated.
- the over-fittings 80, 82 each include a housing member 200 which is connected by a fitting 202 with the valve 110, 112.
- the housing member is connected to a handle portion 204 to facilitate manual insertion into a socket member 206 of the fitting 12, 14.
- sealing surface 208 engages a peripheral wall 210 of an inner well of the socket member 206 in a sealing relationship therewith.
- the housing member 200 defines a spaced chamber 212 around a tubular fitting 214 to which flexible tubing leading to a site to be drained is selectively connected.
- the housing member 200 includes a plurality of spaced projections 216 adjacent one end.
- the projections are spaced from an outer periphery to define an annular passage 218 around an inner wall 220 of the socket 206 in fluid communication with a drain outlet 222.
