  • Publication number: 20250025622
    Abstract: A negative pressure wound therapy device can be configured to monitor motion and determine that the device is falling as well as duration and height of the fall. Flat falls and rotating falls can be accurately detected. The device can provide an indication of the fall, including deactivating therapy. The device can monitor the amount exudate removed from a wound and determine whether transition to a low-exudate rate negative pressure wound therapy and suggest such transition. The device can utilize proportional-inte-gral-derivative (PID) control loop to drive a negative pressure source of the device. The PID control loop can utilize different proportional gain and integral gain for different negative pressure setpoint to achieve target pressure quickly and without any large overshoots.

  • Publication number: 20240293607
    Abstract: A negative pressure device having a negative pressure source, a canister in fluid communication with the negative pressure source, a conduit the can couple with a wound dressing to provide negative pressure to a space beneath the wound dressing. Some arrangements of the negative pressure source can have a first noise reduction chamber and a second noise reduction chamber downstream of and in fluid communication with an outlet of a pump. The first and second noise reduction chambers can be configured to reduce noise generated by the pump and/or a level of pressure pulses in the fluid that is advanced through the negative pressure source.

  • Publication number: 20230037943
    Abstract: A negative pressure wound therapy device can include a negative pressure source configured to be connected, via a fluid flow path, to a wound, a valve positioned in the fluid flow path and configured to, in an open state, permit supply of negative pressure from the negative pressure source upstream of the valve and, in a closed state, block supply of negative pressure from the negative pressure source upstream of the valve, a flow restrictor positioned in the fluid flow path, and a pressure sensor configured to measure a pressure differential across the flow restrictor. The device can include control circuitry configured to, in a normal operational mode, cause the valve to be in the open state and, in a test mode, perform at least one of a leak test, a flow test, or an excessive pressure test.

  • Patent number: 9568189
    Abstract: A thermal reactor for producing usable heat energy by destroying waste including a vessel wherein organic waste upon entering said vessel gasifies as it falls onto a carbon bed and is transformed into a synthesis gas with high heat and kinetic energy that can be harnessed to produce electricity. Inorganic waste upon entering melts as it falls onto the carbon bed and exits via slag ports to form an inert slag. Because there is no oxygen present in the gasification zone, the waste is not combusted and neither furan or dioxin are formed. The waste includes either prepared refuse derived fuel (RDF) or unprepared raw waste or a combination thereof.

  • Publication number: 20130300121
    Abstract: A method and system for the conversion of waste into energy in a sealed system where combustion does not take place and the operating pressure prior to the inlet of the steam or power generating equipment is maintained below atmospheric pressure. Destruction of the RDF (refuse derived fuel) is accomplished by subjecting the RDF to a high temperature environment under controlled conditions in a purpose designed and built reactor. The high temperature environment, <5000° C., is achieved through the use of one or more non-transferred plasma torches for generation of plasma gas. The plasma gas exiting the torch and provides the thermal energy for the continual gasification of metallurgic coke configured as a carbon bed in the lower part of the reactor, which acts as a thermal catalyst and this provides the thermal energy for the gasification process.

  • Patent number: 7201292
    Abstract: A liquid flow-restriction device has a plurality of flow-restriction passages connected to a common outlet. Each flow-restriction passage has a magnetically operable valve having a valve member movable between an open position and a closed position. The valves are operated by a common actuating element selectively positionable with respect to the valve members to open the valves. The actuating element is a permanent magnet. The device is simple and allows easy selection of a flow rate to a dilution dispenser.
