摘要： A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

摘要： A drainage system for draining bodily fluid includes a fluid-receiving body having a fluid-receiving chamber located therein that receives a bodily fluid through an inlet. An actuation device includes a housing with a container-receiving chamber that is sized and configured to receive a pre-evacuated container therein. The actuation device includes an actuation member that, upon actuation, moves either the pre-evacuated container or a piercing element toward the other of the pre-evacuated container or piercing element such that the piercing element pierces a seal of the pre-evacuated container providing communication of a negative pressure inside the pre-evacuated container to a fluid-receiving passageway to draw bodily fluid into the fluid-receiving passageway and toward the fluid-receiving body.

摘要： A surgical drain system for use during and following surgery is provided. A collection reservoir is placed in fluid communication with the body of a user through a collection port. A pump creates a vacuum pressure to urge fluid into the collection reservoir. Fluid exits the collection reservoir through a drain port. A drain mechanism allows air to come into the collection reservoir through an air intake aperture and collected fluid to leave the reservoir simultaneously. The drain system can be worn beneath clothes.

摘要： Methods and apparatuses for detecting full waste canister and/or fluid flow path blockage conditions are disclosed. Also disclosed are methods and apparatuses for controlling a pump. In some embodiments, flow of fluid can be restricted in a portion of the fluid flow path. A controller can be configured to compare a difference in pressure values upstream and downstream of a fluid flow restrictor to a pressure difference threshold, and determine based on the comparison whether to activate an alarm indicating the full waste canister condition or the fluid flow path blockage condition. The controller can be additionally or alternatively configured to determine a fluid flow using a flow meter, open a selectable valve in response to a comparison of the fluid flow with a fluid flow threshold, determine fluid flow after opening the valve, and determine based on the fluid flow after opening the valve whether to activate the alarm.

摘要： Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, negative pressure source, circuit board, and one or more controllers. The circuit board can be supported by the housing and include a conductive pathway extending around at least part of a perimeter of a first side of the circuit board. The conductive pathway can be electrically coupled to an electrical ground for the circuit board. The one or more controllers can be mounted on the circuit board and activate and deactivate the negative pressure source.

摘要： Some embodiments comprise a pump assembly for reduced pressure wound therapy, comprising a housing, a flow pathway through the pump, one or more valves in communication with the flow pathway, a pump supported within or by the housing, and a one-way flow valve in fluid communication with the pump. The pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The one-way flow valve can be configured to substantially prevent a flow of gas through the one-way flow valve in a direction of flow away from the pump. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump has been sterilized following the assembly of the pump such that an inside and an outside of the housing, the flow pathway, the one or more valves, the pump, the controller, the battery compartment, and the at least one switch or button have been sterilized.

摘要： An apparatus (10) for controlling flow of fluid from a wound site of a patient including a cavity (28) connectable to a wound site and a reservoir (16). The cavity (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The cavity (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the cavity (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the cavity (28) from the second state to the first state.

摘要： Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

摘要： In some examples, a dressing filler for treating a tissue site may include a plurality of filler elements and a tissue interface layer. Each of the filler elements may include a first surface and a second surface opposite the first surface and separated from the first surface by a thickness. The tissue interface layer may include a first side configured to be positioned facing the tissue site and a second side positioned opposite the first side. The first surface of each of the filler elements may be coupled to the second side of the tissue interface layer. Also provided are other apparatuses, dressings, systems, and methods suitable for treating a tissue site.
