摘要:
To offload forces from a tissue site being treated with reduced pressure, an offloading pressure component may be used as part of a reduced-pressure treatment system. A reduced-pressure source of the reduced-pressure treatment system vents positive pressure exhaust into the offloading pressure component to inflate the offloading pressure component. The offloading pressure component disperses forces away from the tissue site. Other devices, methods, and systems are presented.

A reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

A reduced-pressure medical treatment system for treating a tissue site on a patient includes a medical drape that has an holographically-formed polymer dispersed liquid crystal (H-PDLC) device that changes visual appearance when experiencing strain. The change in visual appearance of the H-PDLC device allows identification of the existence of strain and may allow a quantitative assessment of the range of stress involved. In other aspects, a dressing conduit connector, canister, and reduced-pressure interface use a holographically-formed polymer dispersed liquid crystal (H-PDLC) device to help determine the existence and perhaps the amount of stress experienced. Other systems, methods, and devices are presented.

Reduced-pressure sources, systems, and methods involve using a vacuum pump that is disposed within a sealed space to produce reduced pressure. The exhaust from the vacuum pump is exhausted from the sealed space through pores in an enclosure member that is made of a polymeric, porous, hydrophobic material. Other devices, systems, and methods are disclosed.
摘要:
Systems and methods are provided for moving fluids from a patient to a canister and lowering or eliminating the bio-burden of the canister. In one instance, a method for removing fluids from a patient includes using reduced pressure to remove fluids from a patient, delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, exposing the fluids removed from the patient to a UV light source to kill pathogens to create disposable fluids, and disposing of the disposable fluids. Other systems, devices, and methods are presented.

A wound treatment system comprises a wound-treatment apparatus and a wound dressing coupled to the apparatus. The wound dressing includes a foam structure wound insert having pores with a greater cross-sectional area when viewed from a first direction and a smaller cross-sectional area when viewed from an orthogonal direction. Methods for making such wound inserts may include compressing foam structure material having pores with a substantially uniform cross-sectional area. Methods for treating a wound using a wound insert.
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 non-motor-driven pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the non-motor-driven 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 non-motor-driven pump to inhibit liquid from entering the non-motor-driven pump.

摘要:
Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.
摘要:
Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.
