Definitions

  • a dynamic, reduced-pressure treatment system for treating a tissue site on a patient includes a manifold for placing adjacent to the tissue site, a sealing member for coupling to the patient's epidermis to form a fluid seal over the tissue site, a reduced-pressure source for producing reduced pressure, a reduced- pressure delivery member for delivering reduced pressure from the reduced-pressure source to the manifold, and a wave generator associated with the reduced-pressure delivery member.
  • the wave generator imparts a wave to the reduced pressure developed by the reduced-pressure source.
  • FIGURE 8 is a schematic cross section of the reduced-pressure delivery member of FIGURE 7 taken along line 8-8.
  • the reduced-pressure subsystem 113 includes a reduced-pressure source 140, which can take many different forms, and may include the reduced-pressure interface 150 or other components to provide reduced pressure to the manifold 112.
  • the reduced-pressure source 140 provides reduced pressure as a part of the dynamic, reduced-pressure treatment system 100.
  • reduced pressure generally refers to a pressure less than the ambient pressure at a tissue site that is being subjected to treatment. In most cases, this reduced pressure will be less than the atmospheric pressure at which the patient is located. Alternatively, the reduced pressure may be less than a hydrostatic pressure at the tissue site 104. Unless otherwise indicated, values of pressure stated herein are gauge pressures.
  • the wave generator 110 allows for a wide frequency range with respect to the absolute value of the pressure experienced at the tissue site 104.
  • the frequency range of the wave may be about 0.5 Hz to about 20 Hz and greater.
  • the wave generator 110 may also control the amplitude of the wave.
  • the wave generator 110 may take many forms, such a piezoelectric transducer, a diaphragm member, a valve arrangement, etc.
  • the first liquid-impermeable-and-gas-permeable member 514 substantially restricts entry into the second lumen 506 to gas while liquids may enter the first lumen 504 (and lumens 516 and 518).
  • the liquid in the first lumen 504 (or lumens 516 and 518) may be used with a wave generator to transmit a wave or may be used to efficiently remove fluids.
  • the wave generator e.g., wave generator 110 in FIGURE 1, may be fluidly coupled to the first interior space 508 of the first lumen 504 and may also be fluidly coupled to the third lumen 516 and the fourth lumen 518.
  • the wave generated by the wave generator is delivered through the liquid, or incompressible fluid, in the first lumen 504 or other lumens.

Abstract

L’invention concerne un système de traitement dynamique à pression réduite générant une pression réduite et une onde rencontrée dans un site tissulaire dans lequel l’onde peut présenter une fréquence comprise entre 0,5 Hz et 20 Hz. Le système contient un collecteur permettant de fournir une pression réduite au site tissulaire, un élément d'étanchéité constituant un joint fluide au-dessus du site tissulaire, une source à pression réduite permettant de fournir une pression réduite, un élément de fourniture de pression réduite pour fournir une pression réduite entre la source de pression réduite et le collecteur et un générateur d’ondes associé à l’élément de fourniture de pression réduite pour impulser une onde dans la pression réduite développée par la source de pression réduite. On peut utiliser un élément de fourniture de pression réduite avec un élément imperméable aux liquides et perméable aux gaz pour contribuer à réduire les blocages et faciliter le traitement. L'invention concerne également d’autres systèmes, appareils et procédés.
