  • the interface connector may comprise a flexible material, such as a polymer, elastomer, or rubber.
  • the interface connector may include an annular member configured to removably engage with the top portion 11 of the cavity 15 .
  • the top portion 11 of the cylindrical body 15 may include a flange extending circumferentially along its external side wall, and the interface connector may have a corresponding snap-on structure configured to engage the flange.
  • a lid may include a rigid rib configured to contact the seal flap 8 when the lid is inserted into the top opening of the cavity 15 .
  • the rigid rib may press down on a surface of the seal flap, causing the seal flap to resiliently deform from an unstressed state to a stressed state.
  • the seal flap exerts a counteracting force against the rigid rib 564 , which enhances the sealing effect between the lid and the receptacle.
  • the interface connector may include a pressure rib extending from its top surface to contact with a bottom surface of the peripheral edge of the lid.
  • the collection bag 30 may be delivered to the medical facility in its fully-collapsed state, as shown in FIG. 4 .
  • the collapsibility of the collection bag 30 into a smaller volume may reduce not only the volume of the medical waste generated, but also the storage area required to store the collection bags 30 prior to their use.
  • the collection bags 30 instead of storing the collection bags 30 in a separate storage location, they may be stored inside the storage space 16 of the main body 12 for convenient access.
  • the exterior of the main body 12 may have one or more attachment members to which extra collection bags 30 may be secured or otherwise attached.
  • the liner 35 is extended to receive fluid, as shown in FIG. 5 .
  • the liner 35 may collapse again into a state that is substantially similar to its original fully-collapsed state. After an acceptable quantity of liquid is removed from the collection bag 30 , it may be removed for disposal in its near-collapsed state.
  • An unused, collapsed liquid collection bag may include a holding mechanism such as a strap or band that assists in maintaining the liner portion of the collection bag in a suitable collapsed position.
  • This holding mechanism assists in maintaining the flexible liner in a suitable collapsed position and holds the flexible liner away from any seals on the lid. This feature allows the bag to be easily positioned at the mouth portion 11 of the cavity 15 and assists in preventing the flexible liner from being pinched between a seal on the lid and the mouth portion 11 of the cavity.
  • the holding mechanism may be configured of a breakable material that breaks, for example, when suction pressure is applied to expand the bag into the interior of the cavity, or as collected liquid expands the bag. Thus, a user does not need to break the band prior to placing the collection bag 30 on the mouth portion 11 of the cavity 15 .
  • the holding mechanism may comprise, for example, paper, plastic, or other suitable material.
  • the lid 31 of the collection bag 30 may sealingly engage the mouth portion 11 of the cavity 15 , so as to form a substantially air-tight enclosure inside the cavity 15 and exterior to the collection bag 30 .

  • the flexible valve 226 may return to its original shape to close the access port 220 .
  • the closure of the access port 220 may keep the collected liquid in the collection bag 230 for transport to the disposal station.
  • the flexible valve 226 may also provide a wiping function on the hose junction 240 during removal from the access port 220 . This wiping function may aid in making the hose junction 240 drip free during its removal and disposal.

  • the disposal connector 340 may be inserted into the access port 220 of the collection bag 230 in a similar manner to how the hose junction 240 is inserted into the access port 220 .
  • the disposal connector 340 may include a drip-free connector valve 345 , which is biased to close the distal end of the disposal connector 340 . Inserting the disposal connector 340 may cause the connector valve 345 to open, so as to establish fluid communication between the access port 220 and the eductor 350 .
  • the eductor 350 may be positioned between a source of water or other rinse fluid 305 and a sanitary sewer 390 to create a pumping force sufficient to draw liquid out of the collection bag 230 .
  • Rinse fluid may consist of water, another wash fluid (e.g. a detergent or other fluid), or a mixture of water and another wash fluid.
  • the term “fluid” may refer to a combination of a liquid medium along with solid particles, gases and/or particulates.
  • the eductor 350 may be connected to the source of water 305 and the sewer 390 via a water conduit 315 and a discharge conduit 380 , respectively.
  • the water conduit 315 may include a water valve 310 , which may be controlled manually or by other control, such as electric switch.
  • a venturi 360 may be suitably positioned, (e.g., adjacent the eductor 350 in the discharge conduit 380 ) so as to create a greater pumping force.
  • the disposal connector 340 may be then connected to the eductor 350 via an evacuation conduit 335 .
  • opening the water valve 310 causes the water from the source of water 305 to flow into the eductor 350 to create a pumping force in the eductor 350 .
  • This pumping force causes the liner 235 to collapse and then liquid collected in the collection bag 230 to flow into the eductor 350 and then into the sanitary sewer 390 via the discharge conduit 380 .
  • check valve 286 may be set in a closed position. The closed position of the check valve 286 prevents air from flowing into the space between the liner 235 and the container 215 .
  • the three-way valve 265 may be aligned to communicate the lower space 289 with atmosphere via the first and second connections 262 , 264 , as shown in FIG. 34 . This selection allows the pressure inside the lower space 289 to reach atmospheric pressure during the evacuation process, so as not to interfere with the collapse of the liner 235 .
  • maintaining the pressure in the lower space 289 at atmospheric pressure allows the piston 280 to rise during the evacuation process, due to a differential pressure between the upper space 281 (which is subject to a suction pressure) and the lower space 289 (which is open to atmosphere). Because the piston 280 moves up as the liner 235 collapses, the collapse of the liner 235 takes place primarily near the piston 280 , and occlusion of the sidewalls of the liner 235 during the evacuation process may be effectively prevented.
  • the disposal station 300 may include a pipe conduit 325 , that branch from the water conduit 315 to supply cleaning water to the disposal connector 340 .
  • the pipe conduit 325 may include a valve 320 (e.g., an electric solenoid valve, a ball valve) that controls the water flow into the interior of the disposal connector 340 .
  • a valve 320 e.g., an electric solenoid valve, a ball valve
  • clean water from the source of water 305 may flow into the interior of the disposal-connector 340 , which can be cycled on and off one or more times for rinsing or flushing purposes, and as preventive maintenance for the disposal connector 340 .
  • the operation may occur before the discharge connector 340 is removed from the access port 220 , for example, so that cleaning water may flow to the exterior of discharge connector 340 and then be suctioned back through the interior of discharge connector by the suction of the eductor.
  • the disposal connector 340 may communicate with two channels: one channel that supplies clean, rinse fluid and a second channel that evacuates contaminated fluid.
  • the second channel for example, may be situated within the first channel, as shown in FIG. 32 and as similarly shown and described with respect to FIG. 51 .
  • a valve such as a ball valve, is located within one of the channels. After the collected contents of a liquid collection container have been evacuated, rinse fluid flows from the first channel into and around the valve, flushing the entire surface of the valve. If the valve is a ball valve, the rinse fluid flows in a cylindrical path around the valve housing so that the valve is completely rinsed with the rinse fluid. Via the valve, the rinse fluid enters the second channel and is evacuated, similar to the contents of the liquid collection container. Thus, the second channel is also flushed with rinse fluid.
  • This approach allows the disposal connector to automatically clean both itself and the connection with the liquid collection container. Among other things, this automatic rinse feature prevents a user from coming into contact with liquid collected in a medical procedure.
  • conduit 325 (which supplies cleaning water to the disposal connector 340 ) is in fluid communication with discharge conduit 380 , which is used to “charge” the eductor 350 , and to thereby suction fluid from the collection bag 30 (as described above). In this manner, cleaning fluid will not be supplied to the disposal connection 340 unless the eductor is suctioning fluid from the collection bag 30 , thereby preventing unintended flooding of the collection bag 30 with cleaning water.
  • the discharge connector 340 is removed from the access port 220 .
  • the flexible valve 226 then closes the access port 220 , so as to seal the collection bag 230 and to maintain the bag 230 in the collapsed state.
  • the collection bag 230 is then removed from the container 215 and placed in a red bag for disposal, for example.
  • a new collection bag 230 ′ may be placed onto the container 215 for the next series of medical procedures, as shown in FIG. 35 .
  • Access ports may include a normally-closed, flexible slit valve, for example, a flexible, anti-drip, check valve.
  • This valve may be made of a flexible material such as plastic, rubber, or other suitable material.
  • the valve acts as a normally closed two-way check valve. The valve resists back pressure such that it assists in maintaining vacuum pressure within the liquid collection bag.
  • This approach assists in maintaining an unused bag and a previously used, evacuated bag in a substantially collapsed state.
  • This approach further provides a safety feature by preventing waste in the collection bag from dripping from or exiting the bag. Thus, an evacuated collection bag will not leak waste if it is turned upside down or squeezed.
  • the piston 580 may also include one or more sealing members, such as O-rings 588 attached to an outer peripheral edge of the main body 585 .
