  • Patent number: 8486032
    Abstract: Reduced-pressure treatment systems and methods are disclosed that employ debridement mechanisms to remove unwanted tissue. In one instance, a reduced-pressure treatment system for treating a tissue site on a patient includes a manifold member for distributing reduced pressure to the tissue site, a support member for disposing proximate the tissue site and the manifold, and a debridement mechanism coupled to the support member. The debridement mechanism is for debriding the tissue site. The system further includes a sealing drape for placing over the tissue site and manifold member. The sealing drape is operable to form a fluid seal over the tissue site and manifold member. The system also includes a reduced-pressure subsystem for delivering a reduced pressure to the sealing drape. The system may further include a chemical-debridement subsystem. Other systems, manifolds, and methods are disclosed.

  • Patent number: 8486050
    Abstract: A bubble-type nose cleaner includes a container, an electromagnetic pump, a nose-washing tool, and at least a bubble generating valve. The container has a containing space for storing a cleaning solution. The electromagnetic pump is communicated with the container through a negative pressure channel. The nose-washing tool is communicated with the electromagnetic pump through a positive pressure channel, thereby the nose-washing tool is applied with the cleaning solution drawn by the negative pressure and then discharges the cleaning solution when the electromagnetic pump actuates. The bubble generating valve is provide at a negative pressure channel or a positive pressure channel and has an air inletting opening provided at the negative pressure channel or the positive pressure channel for communicating the exterior with the interior, wherein a cap is used to control the gas-flow rate of the bubble generating valve.

  • Patent number: 8386084
    Abstract: An object is to prevent a mistaken shutoff caused by the mistaken registration of an appliance of which an amount of gas used changes. An individual flow registration maintenance unit maintains a registered flow rate deleted due to an increase/decrease in flow rate, again, performs determination on the flow rate maintained when a new flow rate is registered or a flow rate added with the maintained flow rate, and in the case where it is regarded to be the same, re-register the maintained flow rate.

  • Patent number: 8372060
    Abstract: A reduced pressure treatment system includes a filament delivery conduit having a distal end positioned at a subcutaneous tissue site of a patient and a proximal end positioned extracorporeal to the patient. A continuous filament is positioned in the filament delivery conduit such that one end of the continuous filament extends from the proximal end of the filament delivery conduit and another end of the continuous filament extends from the distal end of the filament delivery conduit. The continuous filament forms a filament mass adjacent the tissue site. A reduced pressure delivery conduit is adapted to fluidly communicate with a reduced pressure source and the filaments mass to deliver a reduced pressure to the tissue site through the filament mass.

  • Patent number: 8366690
    Abstract: A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.

  • Patent number: 8323264
    Abstract: A negative pressure wound therapy apparatus that can include a wound dressing, a fluid collection device, a vacuum pump comprising a pump motor, and tubing can be powered by auxiliary power sources such as high efficiency batteries, photovoltaic panels or cells, fuel cells, combustion generators, human powered generators, or other mechanical, electrical, or chemical power sources such as hand operated dynamos or wound springs, or any combination of the foregoing. Additionally, the apparatus can include a high efficiency pressure controller for controlling the output of the vacuum pump. In some embodiments, the pressure controller can control the pump without using a processor, and can have other features such as an intermittent delay function and an anti-stall mechanism to reduce the energy consumption of the apparatus.

    Abstract: River rocks are used in a therapy regime whereby the river rocks are used to absorb excess oils from the skin of a user. In one method, river rocks are collected from a source (e.g., river or supplier), sorted for size and color, engraved with logo or other content, packaged and shipped to customers or retailers with instructions on use. Use comprises placement of the river rocks on oily portions of the user's skin for an appropriate time period allowing the river rock to absorb the excess oils. The river rocks are reusable after being washed with mild soap and water.
