摘要： Some arrangements disclosed herein relate to devices and methods for treating a wound, comprising applying negative pressure to the wound through a cover applied over a wound, monitoring the internal pressure in the wound, and controlling the closure of the wound by controlling the amount that a wound packing material positioned under the cover collapses within the wound based on the monitored internal pressure. The wound packing material collapse can be controlled to ensure that the monitored internal pressure does not exceed a threshold value. Additionally, some embodiments or arrangements disclosed herein relate to a visualization element to visualize a location of a wound surface. The visualization element can comprise a radiopaque member that is configured to be positioned on or adjacent to a surface of an open wound.

摘要： Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

摘要： A medical/surgical waste collection rover includes a first waste container disposed on a portable cart and receiving waste under the influence of a vacuum. A fluid measuring system includes a float element disposed within the first waste container, and a controller causing liquid in a reservoir disposed on the cart to prefill the first waste container and subject the float element to an initial lifting to a zero point level. The fluid measuring system determines a volume of contents within the first waste container based on a position of the float element relative to the zero point level. The fluid measuring system may include a sensor rod extending through the first waste container and a second waste container disposed on the cart and separated from the first waste container by a transfer valve. Methods of estimating the volume of liquid and/or medical/surgical waste within the waste container are also provided.

摘要： Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values.

摘要： The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

摘要： A surgical waste collection unit with a receiver for removably holding a manifold to which suction lines are connected. The receiver is mounted to the waste collection unit to be at an acute angle relative to the horizontal. The receiver is further configured to allow the manifold to be rotated in the receiver. This means the manifold can be rotated from a first position in which the manifold outlet opening is aligned with the conduit through which waste is flowed from the receiver and a second position in which the manifold outlet opening is elevated relative to the first position.

摘要： Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure. In one embodiment, a reduced-pressure dressing may include a dressing bolster, a retention pouch, and a sealing member. The dressing bolster may be adapted to apply a compressive force to the tissue site capable of closing a wound or incision therein. The retention pouch may be adapted to retain and manage fluid extracted from the tissue site to keep the tissue site substantially free of fluid and to prevent clogging of the reduced-pressure dressing. The sealing member may provide a seal over the retention pouch, the dressing bolster, and a portion of the epidermis of the patient. Other dressings, systems, and methods are disclosed.

摘要： An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture. The apparatus also may include a conduit port fluidly coupled to the cavity and adapted to receive a conduit. The base may be adapted to couple to the dressing, and the wall may be adapted to collapse from a first position to a second position in response to a supply of reduced pressure from the reduced-pressure source.

摘要： Embodiments of a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.
