THERAPY GAS STORAGE AND DELIVERY APPARATUS

摘要

A mobile dressing for delivering pressurized therapy gas to a wound. The dressing may include an inflatable structure for creating a sealed cavity around the wound. The inflatable structure further may include a dimple and an aperture within the dimple. A first lumen may be fluidly connected to the aperture for delivering pressurized therapy gas to the dimple. A second lumen may be fluidly connected to the opening for delivering pressurized gas to the inflatable structure. A first pump may include a first intake port fluidly connected to a first reservoir of therapy gas, as well as a first discharge port fluidly connected to the first lumen for supplying therapy gas at an increased pressure. A second pump may pressurize air for inflating the inflatable structure and creating a sealed cavity over the wound. Pressurized therapy gas may be administered to the wound in the sealed cavity.

1. A mobile dressing for therapeutically delivering pressurized therapy gas to a wound comprising:
an inflatable structure for creating a sealed cavity around a wound which comprises
a flexible container for receiving pressurized gas, the flexible container comprises
an interior chamber for containing pressurized gas, andan opening in the interior chamber for receiving pressurized gas,a wound-facing surface which comprises
a dimple, andan aperture within the dimple,a first lumen fluidly connected to the aperture for delivering pressurized therapy gas to the aperture, anda second lumen fluidly connected to the opening for delivering pressurized gas to the interior chamber; a first pump which comprises
a first intake port fluidly connected to a first reservoir of therapy gas at a first pressure, anda first discharge port fluidly connected to the first lumen for supplying therapy gas from the first reservoir at a second pressure that is greater than the first pressure; a second pump which comprises
a second intake port fluidly connected to a second reservoir of gas at a third pressure, anda second discharge port fluidly connected to the second lumen for supplying pressurized gas from the second reservoir at a fourth pressure that is greater than the third pressure; the mobile dressing having a plurality of operable configurations which comprise
a first operable configuration such that the interior chamber contains a first volume of gas from the second reservoir at the third pressure, anda second operable configuration such that the interior chamber contains a second volume of gas from the second reservoir at the fourth pressure, and the first discharge port supplies therapy gas from the first reservoir to the aperture at the second pressure.
