摘要： A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, including a wound dressing dimensioned for positioning relative to a wound bed of a subject and a subatmospheric pressure mechanism dimensioned to be carried or worn by the subject. The subatmospheric pressure mechanism includes a housing having a control unit adapted to draw a vacuum and a canister associated with the housing. The canister has a collection bag disposed therein, which is in fluid communication with the wound dressing to receive exudates from the wound bed. The collection bag is adapted to expand upon receipt of the fluids and has means to release gas from within the collection bag in connection with operation of the control unit. With this arrangement, the canister is attitude independent, i.e., the canister may be positioned on edge, on its side or on its end etc. while still maintaining operation of the control unit. The collection bag may include a hydrophobic vent or material for releasing the gases. In another embodiment, the collection bag comprises a gas permeable material. The collection bag may include one of pleats or bellows.

摘要： The present invention discloses a negative-pressure oral apparatus capable of relieving discomfort of soft tissues in the oral cavity and improving fixation of the oral apparatus to prevent the oral apparatus from falling off due to mouth opening. The oral apparatus is compact and elastic so that it fits various shapes and sizes of the oral cavity and is easy to be put on and taken off to provide convenience and safety to the user. In another embodiment, a method for maintaining a negative oral pressure and collecting liquid by coupling the oral apparatus to a liquid collecting apparatus capable of effectively providing the oral cavity with a negative pressure to expel liquid in the oral apparatus and deliver the liquid to an absorbing element in the liquid collecting apparatus so as to prevent liquid leakage or contamination.

摘要： A portable apparatus for collection and processing of human biological material containing adipose, such as extracted during a lipoplasty procedure, is useful for multi-step processing to prepare a concentrated product (e.g., stromal vascular fraction) or a fat graft composition. The apparatus has a container with an internal containment volume including an available processing volume in a range of from 75 cubic centimeters to 1300 cubic centimeters, and with a tissue retention volume and a filtrate volume separated by a filter and with a tapered portion to a collection volume for collecting concentrate product. The apparatus has a mixing device for mixing contents within the tissue retention volume, and including a rotatable shaft extending from outside of the internal containment volume to inside of the internal containment volume and comprises at least one mixing member that is disposed in the tissue retention volume and is connected with the shaft to move through the tissue retention volume relative to the filter when the shaft is rotated. Methods include use of the apparatus to process human biological material containing adipose, such as to prepare a stromal vascular fraction concentrate product or a fat graft composition.

摘要： A computer-implemented method for quantifying fluid includes estimating a first volume of a first fluid contained in an item based on a difference between a dry weight and a wet weight of the item, and displaying a graphical representation of a container containing a volume of a second fluid and a second volume of the first fluid, wherein the graphical representation includes a first display element for receiving a first user input indicating the volume of the second fluid in the container, and a second display element for receiving a second user input indicating a total fluid volume in the container, estimating the second volume of the first fluid based on at least one of the first and second user inputs, and estimating a quantity of the first fluid based on the first and second volumes of the first fluid.

摘要： A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber.

摘要： Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a negative pressure source, a wound dressing configured to be positioned over a wound, and optionally a canister configured to store fluid aspirated from the wound. The negative pressure source, wound dressing, and canister (when present) can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to automatically detect whether the canister is positioned in the fluid flow path between the negative pressure source and the dressing while negative pressure source provides negative pressure to the wound dressing. Operation of the system can be adjusted based on whether presence of the canister has been detected. For example, a value of an operational parameter can be set to indicate that the canister is present.
