  • Patent number: 11628094
    Abstract: A wound therapy system includes a therapy unit, a wound dressing and an optional controller. The therapy unit is configured to deliver instillation fluid to a wound site. The wound dressing is formed from a plurality of discrete, individual blocks that are selectively separable from one another along a plurality of separation-lines, allowing the wound dressing to be customized to the shape and size of the wound site. By calculating the remaining blocks that define the wound dressing following customization, the volume of the wound dressing may be determined. The controller may be configured to deliver fluid to the wound site based on this calculated volume. The controller may also optionally be used to gauge the healing of the wound site over time by monitoring the changes in volume of customized wound dressings as wound dressings are replaced during the course of treatment of the wound site.

  • Patent number: 11253401
    Abstract: A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.

  • Publication number: 20220001100
    Abstract: A wound therapy system includes a single conduit fluidly connecting a wound site to a. removed fluid canister. A negative pressure circuit is defined by the wound site, the conduit, the removed fluid canister and tubing extending between the removed fluid canister and a pneumatic pump that applies negative pressure to the negative pressure circuit. A method of operating the wound therapy system includes profiling and benchmarking pressure decay within the negative pressure circuit against previous and/or expected pressure decay to identify any new or sudden anomalies that occur during the operation of the wound therapy system. The wound therapy system may additionally alert a user to such anomalous operation of the wound therapy system and/or identify and alert a user to an underlying cause (e.g, blockage and/or leak, etc.) that is responsible for the anomalous readings.
