  • Patent number: 11806468
    Abstract: Embodiments of secure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, the apparatus includes a pressure source, a user interface, and a locking mechanism. The locking mechanism can be in one of at least two states, the at least two states including a first state in which the locking mechanism physically prevents user adjustment of one or more operational parameters with the user interface and a second state in which the locking mechanism does not physically prevent user adjustment of the one or more operational parameters with the user interface. The locking mechanism can include an authentication key and a receiver configured to receive an authentication input, which may be compared to the authentication key. Providing a sufficiently matching authentication input can transition the locking mechanism from the first state to the second state, permitting adjustments to the one or more operational parameters.

  • Patent number: 11793924
    Abstract: Embodiments of delivering reduced pressure wound therapy are disclosed. In some embodiments, a system includes a reduced pressure wound therapy device and a remote computer. The device can be configured to apply reduced pressure to a wound of a patient according to a default reduced pressure therapy prescription. The device can be configured to monitor usage data and transmit the usage data to the remove computer for determining compliance with a reduced therapy prescription. In some cases, non-compliance can be determined due to change of the prescription from the default prescription to a prescription more suitable for treating the wound. A non-compliance notification can be transmitted to the device. The device settings can be updated to the current prescription.

  • Patent number: 11744932
    Abstract: A negative pressure wound therapy device can include a negative pressure source and a controller configured to activate the negative pressure source for a first duration of time to attempt to reduce pressure under the wound dressing to approximately a negative pressure set point, subsequent to expiration of the first duration of time, deactivate the negative pressure source after pressure under the wound dressing is reduced to approximately the negative pressure set point, activate the negative pressure source for a second duration of time to attempt to reduce pressure in the fluid flow path, the second duration of time subsequent to the first duration of time, determine a pressure change in a fluid flow path over the second duration of time, and, in response to determining that the pressure change in the fluid flow path over the second duration of time indicates reduction in pressure, provide indication of a blockage.

  • Patent number: 11564844
    Abstract: According to certain embodiments, an apparatus for applying negative pressure to a wound can include a negative pressure source, a sensor, and a controller. The negative pressure source can be configured to couple via a fluid flow path to a wound dressing and provide negative pressure to the wound dressing. The sensor can be configured to monitor a magnitude or frequency of pressure in the fluid flow path generated by the negative pressure source. The controller can be configured to determine an activity classification, such as breathing, changing positions while lying, sitting, walking, standing, jumping, traversing stairs, leg extending, leg bending, and performing chair squats, based on a change in the magnitude of pressure over time while the negative pressure source maintains the magnitude of pressure in the fluid flow path below a negative pressure threshold. The controller can output an indication of the activity classification.
