Systems, assemblies, and methods for providing negative-pressure therapy to a tissue site are described. The system can include an absorbent and a sealing layer configured to cover the absorbent. The system can also include a blister fluidly coupled to the absorbent. The blister may have a collapsed position and an expanded position. A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.

A device for an aspirator, the device comprising a suction inlet for suctioned air, liquid and particles; an exhaust outlet for air; a reservoir for collecting liquid and particles separated from the air; and a clearing arrangement fluidly between the suction inlet and the exhaust outlet, the clearing arrangement being configured to provide a path of air, substantially cleared from liquid sucked through the suction inlet, to the exhaust outlet, in any orientation of the device in space. An aspirator comprising a device, and a method of modifying a device for an aspirator, are also provided.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

This disclosure includes wound dressings and systems for effluent management of topical wound therapy and related methods. Some devices, which are configured to dilute therapeutic gas effluent flowing from a dressing, comprise a therapeutic gas source configured to provide therapeutic gas to the dressing; a container comprising a sidewall that defines a chamber configured to receive therapeutic gas effluent from the dressing; a negative pressure source configured to be coupled to the container such that the negative pressure source can be activated to draw fluid from the dressing through the chamber of the container; and a diluent gas source configured to deliver a diluent gas to dilute therapeutic gas effluent before the therapeutic gas effluent enters the negative pressure source.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

A waste collection unit for collecting waste material. A reservoir is supported on a portable cart for storing a liquid on the portable cart when positioned away from a docking station. A sprinkler may be coupled to the waste container and in fluid communication with the reservoir. The sprinkler is configured to direct the liquid from the reservoir towards the waste container. The reservoir is configured to receive additional liquid from the docking station to urge the liquid from the reservoir towards the sprinkler. A prefill pump may be supported on the portable cart and in fluid communication with the waste container and operable to convey the liquid from the reservoir to the waste container. A controller may be in electronic communication with a valve assembly to control flow of the liquid from the docking station into at least one of the reservoir and a second waste container.

Disclosed is a vessel for recovering adipose tissues including a body sealed by a lid connectable to a first pipe with a suction cannula, and a second pipe with a suction pump. A removable adapter connects a lid including two orifices, each closed by a stopper that can be pierced or is pre-pierced and self-sealing, and a vent opening with a filter and removable plug. The connection adapter includes two rigid piercing tubes projecting from under the adapter, each piercing tube in continuous fluid relationship with a corresponding nipple projecting from the adapter, each nipple connectable to a corresponding pipe. The two sealed orifices of the lid and the adapter and piercing tubes are arranged so, when the connection adapter is applied to the lid, each piercing tube pierces a corresponding stopper and brings each nipple into correspondence, in a sealed manner, with the internal volume of the vessel.

An automatic urine treatment system according to an embodiment of the present invention includes a receiver for receiving wearer's excrement; a main body including a urine tank for receiving and storing urine from the receiver, and a vacuum pump for sucking air into the urine tank and transferring a negative pressure to the receiver; and a first connecting hose connecting the receiver and the urine tank. A strip accommodation unit for accommodating a strip for analyzing components of the stored urine through color change is formed inside the urine tank, and on the outer surface of the urine tank, urine analysis is performed using a first optical sensor unit for sensing color change of the strip, and a second optical sensor unit for sensing at least one among turbidity and color change of the stored urine. There is an advantage of being able to confirm the health condition of disabled or elderly people in real-time through the urine information analyzed in this way.

In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly including a fluid restraint configured to reduce a fluid capacity of the fluid management assembly proximate to the fluid restraint. Other features may be associated with the dressing including, by way of example and without limitation, abase layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

The present invention is directed to improved methods, devices, and systems for eye surgery. In some embodiments, the invention may provide new and/or improved devices, systems, and methods for detecting surgical fluids in a fluidics cassette, particularly cassettes which are used to couple an eye treatment probe to an eye treatment console. Rather than relying on internal reflection by a gas-liquid interface, the fluid detection techniques described herein may make use of the changes in propagation of light through a portion of the holding tank when the portion varies between empty and full. Other aspects of the invention may provide devices, systems, and methods for producing different types of fluidics cassette using a single cassette body type.
