  • Patent number: 11426509
    Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a negative pressure source, a wound dressing configured to be positioned over a wound, and optionally a canister configured to store fluid aspirated from the wound. The negative pressure source, wound dressing, and canister (when present) can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to automatically detect whether the canister is positioned in the fluid flow path between the negative pressure source and the dressing while negative pressure source provides negative pressure to the wound dressing. Operation of the system can be adjusted based on whether presence of the canister has been detected. For example, a value of an operational parameter can be set to indicate that the canister is present.

  • Patent number: 11395870
    Abstract: Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

  • Publication number: 20220162126
    Abstract: Techniques of forming a foamed insulation material from gypsum waste are disclosed herein. One example technique includes mechanically comminuting the gypsum waste from an original size into particles of gypsum at a target size smaller than the original size and mixing the particles of the gypsum with a binder to form a mixture of particles and binder. The binder is configured to bind the particles of gypsum upon hydration. The example technique can further include performing air entrainment on the mixture until a foam is formed from the mixture having the particles of gypsum and binder. The foam has water that causes the binder to bind the particles of gypsum. The example technique can then include removing moisture from the mixture with the formed foam to form a foamed insulation material from the particles of gypsum.

  • Publication number: 20210369362
    Abstract: A robotic surgical instrument comprising a shaft, an articulated section and a drive mechanism. The articulated section extends from the shaft and terminates at its distal end in a tip. The tip has an attachment for an end effector. The drive mechanism drives the articulated section via flexible driving elements thereby altering the angular orientation of the tip relative to the shaft. The drive mechanism is controlled so as to always fully compress the articulated section along at least one extent by which the articulated section connects the tip and the shaft whilst driving the articulated section from any one configuration to any other configuration. The drive mechanism constrains movement of the articulated section so as to permit the tip to move with two degrees of rotational freedom and no degrees of translational freedom relative to the shaft.
