    摘要： A negative pressure wound therapy device can include a negative pressure source and a controller configured to activate the negative pressure source for a first duration of time to attempt to reduce pressure under the wound dressing to approximately ae negative pressure set point, subsequent to expiration of the first duration of time, deactivate the negative pressure source after pressure under the wound dressing is reduced to approximately the negative pressure set point, activate the negative pressure source for a second duration of time to attempt to reduce pressure in the fluid flow path, the second duration of time subsequent to the first duration of time, determine a pressure change in a fluid flow path over the second duration of time, and, in response to determining that the pressure change in the fluid flow path over the second duration of time indicates reduction in pressure, provide indication of a blockage.

    摘要： An electric breast pump 1 includes a breast placement part 12 at which a breast part including a breast and a nipple of a subject is placed and suction-pressure generating units 10 and 50 that generate a suction pressure in the breast placement part. The suction-pressure generating unit generates a suction cycle including a plurality of different suction pressures. The suction cycle includes basic suction, increased suction with an increased suction pressure, and reduced suction with a reduced suction pressure. A suction pressure difference between a suction pressure increasing in the increased suction and a suction pressure reducing in the reduced suction is an equal pressure and is a pressure difference at a borderline at which a user perceives a change of a suction pressure. In the suction cycle, the basic suction, the increased suction, and the reduced suction are each repeated multiple times consecutively at an equal suction pressure.

    摘要： Disclosed herein are apparatuses and methods for treating, a wound by applying reduced or negative pressure to the wound. The apparatus can include a wound cover, a fluid collection container, a vacuum pump, an inflation pump, and one or more conduits. The wound cover can be configured to move between at least a relatively rigid, generally raised position and a relatively flexible, generally collapsed position according to a predetermined program or in response to input from a user or one or more sensors. In some embodiments, the wound cover can be configured to move between at least the relatively rigid, generally raised position and the relatively flexible, generally collapsed position by adjusting the air pressure in one or more channels in the wound cover or by adjusting the length of piezoelectric or other length changing material supported by the wound cover.

    摘要： A vacuum aspiration control system for use with a vacuum source and an aspiration catheter includes a connection tubing configured to act as a fluid conduit between the vacuum source and the aspiration catheter. A controllable valve is configured to control a level of vacuum in the connection tubing provided by the vacuum source, and one or more pressure sensors are associated with the connection tubing. A controller is configured to periodically sample flow when the current flow state is unrestricted, utilize an artificial neural network to classify a flow state for the sampled flow, close the controllable valve if the flow state for the sampled flow is classified as unrestricted, and hold the controllable valve open if the flow state for the sampled flow is classified as restricted or obstructed.
