A triple-chambered container includes: a main container body with a first chamber which has an opening at its distal end; a main barrel formed and movable longitudinally within the first chamber, the main barrel defining therein a second chamber for receiving fluids, the main barrel further having an apertured stopper at its distal end; a second barrel formed within the main barrel, the second barrel defining a third chamber for receiving fluids, the second barrel being movable longitudinally within and with respect to the main barrel, the second barrel having a distal end which is engageable and disengageable with the apertured stopper; a shaft adapted to fit within the second barrel, the shaft being movable longitudinally within and with respect to the second barrel, the shaft having a distal end which is engageable and disengageable with an aperture in the second barrel; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the second barrel. The first chamber, the second chamber and the third chamber may be selectively moved to receive and discharge fluids with respect to one another.

In some examples, a system for treating a tissue site may include a dressing, at least one fluid sampling conduit, and at least one fluid sampling assembly. The dressing may be configured to be positioned at the tissue site. The at least one fluid sampling assembly may be configured to be in fluid communication with the tissue site through the at least one fluid sampling conduit. The at least one fluid sampling assembly may include a fluid vessel for receiving a fluid from the tissue site. The fluid may be a sampling fluid communicated directly from the tissue site and representative of the physiological condition of the tissue site. Other devices, systems, and methods are disclosed.

Filtering cassettes, filtering systems, and methods for using the same are disclosed. An example filtering cassette may include a cassette housing. An inlet may be coupled to the cassette housing. The inlet may be configured to receive cerebrospinal fluid from a catheter. An outlet may be coupled to the cassette housing. The outlet may be configured to direct filtered cerebrospinal fluid to the catheter. One or more filters may be disposed within the cassette housing. An arcuate surface may be defined along a periphery of the cassette housing. The arcuate surface may be configured to engage a controller assembly when the cassette housing is mounted to the controller assembly.

A waste collection unit is provided that comprises a vacuum pump and smoke evacuation system including a blower and blower motor. The vacuum pump, the blower, and the blower motor, create noise. This noise is attenuated in first and second sound attenuating enclosures for the vacuum pump and the blower and blower motor. A cleaning system is also provided with rotating liquid delivery devices. An actuator is operatively coupled to the liquid delivery devices to rotate the liquid delivery devices.

A system suitable for collecting and transporting urine away from the body of a person or animal may include an assembly having a fluid impermeable casing, a fluid permeable membrane, and a fluid permeable support. A reservoir is defined by the fluid permeable support. The fluid permeable membrane can define a cavity. The casing can define an opening such that the cavity is accessible via the opening. The assembly can also include an outlet in fluidic communication with the reservoir. The assembly can be arranged such that a user's penis can be disposed through the opening with the urethral opening disposed within the cavity and such that a fluid can flow into the body from the urethral opening of the user's penis, collect in the reservoir, and flow out of the outlet.

A surgical tool, systems, and method for cleaning an anatomical space is provided. At least one brush is disposed on a shaft extending through a tube. The tube includes a corresponding brush slot for each brush. A motor is operable to rotate the shaft to cause the at least one brush to move from a closed position to a cleaning position. The at least one brush is positioned entirely inside of the tube when in the closed position and at least partially outside of the tube when in the cleaning position. A fluid source is operable to supply fluid to the at least one brush as the at least one brush passes through the brush slot.

The Bone Dust Trap for collecting bone dust during various surgical procedures for subsequent bone graft implantation. The device includes cylindrical housing unit covered with the lid, attached to the central pipe with the porous tip. The pipe connects the cyclone forming mechanism and filtrating membrane, located at the lower part of the central pipe. The membrane interlinks with the plurality of porous plates located along the walls of the cylinder. The cyclone forming mechanism, consisting of the inlet port with conical jet and the spiral helix, creates spiral movement of the incoming fluid. The liquid is further directed towards the 2-stage filtrating system with the said porous plates, where larger bone particles are accumulated, and then to the filtrating membrane, which collects smaller particles. The fluid is extracted through the central pipe. The lid can be removed to collect the bone particles from plates and membrane.

Disclosed is a covering/lid assembly having a first compartment, a second compartment, or both. Each compartment will comprise a top side and a bottom side, the bottom side of the compartment comprising a frangible material. The first or second compartment may comprise a first material or a second material. The first or second material may comprise a flocculated red blood cell coagulant, or a red blood cell flocculent. The material within a compartment may be selectively released upon compressing a dimple and/or button located directly above the first and/or second compartment. A collection and/or biological waste management and disposal system is presented, comprising a lid/covering assembly as described and a collection container. The lid may include a perimeter having a threaded and/or snap-on assembly suitable for securely attaching the lid to a collection canister. The collection canister may comprise a red blood cell flocculent coating.

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

A system, method, and apparatus for the collection of surgical/wound fluid from a subject patient with the capability of simultaneous fluid removal from a plurality of such wounds and/or wound through the utilization of a single pump device worn by such a patient. Such a system, method, and apparatus allow for such a single pump device to collect surgical/wound fluid within a single site collection component attached to or associated with such a single pump device. Multiple fluid transfer lines may be incorporated with the single pump device leading to such plurality of wounds and/or wound sites for greater versatility and comfort for the subject patient, as well as cleaner removal capabilities than in the standard apparatus systems and method currently undertaken within the industry.
