摘要： A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

摘要： A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

摘要： Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of the diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber. Improved heater control circuitry is also disclosed, to provide added or redundant safety measures, or to reduce current leakage from a heater element during pulse width modulation control of the heater element. Improvements are also disclosed in an application of negative pressure during a drain phase in peritoneal dialysis therapy, and to control an amount of intraperitoneal fluid accumulation during the therapy. Improvements in efficiency are also disclosed in movement of fluid into and out of a two-pump cassette and a heater bag of the peritoneal dialysis cycler, and in synchronization of operation of two or more pumps in the peritoneal dialysis cycler or other fluid handling devices using a multi-pump arrangement.

摘要： Disclosed herein are aspiration catheters having grooved inner surfaces for removing clot material from the vasculature of a patient, and associated systems and methods. In some embodiments, an aspiration catheter can include a proximal terminus, a distal terminus, and an inner surface defining a lumen. The inner surface includes at least one groove formed therein and that extends from the distal terminus at least partially toward the proximal terminus. When clot material is aspirated through the aspiration catheter, the at least one groove can provide a leak path past the clot material to improve the ingestion of the clot material through the catheter and inhibit clogging.

摘要： A cassette for retrieving plural tissue samples from a fluid stream. The cassette includes a bypass conduit and plural voids. A catch tray is removably seated in each of the voids. A fitting extends from the cassette. The cassette has an outlet opening through which a suction is drawn. The cassette also has a valve. The valve directs the fluid stream from the fitting so the fluid stream flows through the bypass conduit or through one of the voids in which a catch tray is seated.

摘要： Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

摘要： A suction catheter system is described with a suction extension interfaced with a guide catheter to form a continuous suction lumen extending through a portion of the guide catheter and through the suction extension. The suction extension can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. The suction extension can comprise a connecting section with a non-circular cross section for interfacing with the inner lumen of an engagement section of the guide catheter. The tubular body of the guide catheter can have a reduced diameter distal section the can be useful to restrain the movement of the suction extension. Proximal fittings attached to the guide catheter can facilitate safe removal of the catheter system from the patient by allowing for the removal of some or all of a tubular extension of the suction extension from the guide catheter behind a hemostatic seal. Pressure sensors connected to the proximal fittings can help to guide the procedures with reduced risk of embolizing thrombus.

摘要： A surgical drain tray assembly includes a fluid impermeable first layer and a porous second layer positioned on the fluid impermeable first layer. The fluid impermeable first layer includes a drain outlet, a basin, and a sloping surface angled toward the basin, the drain outlet being positioned within the basin. The porous second layer may be formed of a foam material and includes a top work surface. Fluids spilled onto the work surface pass through the porous second layer to the fluid impermeable first layer. The sloping surface of the fluid impermeable first layer conveys the fluids toward the basin for draining through the drainage outlet.

摘要： An apparatus having a separation cell for separating drops of biological liquid from transport air in a flow coming from an endoscope is provided. The separation cell has an inner chamber having an upper inlet fluidically connectable to the endoscope, for receiving a flow containing drops of biological liquid mixed with transport air, a bottom outlet for exit of the drops of biological liquid, fluidically connectable to a suction pump and to an element for collecting and/or analyzing the drops of biological liquid, and an upper outlet for exit of the transport air and optionally of the drops of biological liquid and/or rinse water, fluidically connectable to a vacuum source. The separation cell forms a depression arranged between the upper inlet and the upper outlet. The depression extends downwards into the inner chamber and determines, for incoming transport air, a V-shaped path between the upper inlet and the upper outlet.
