  • Patent number: 11980449
    Abstract: A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment, including either suspending or adjusting turn schedule based on various types of patient movement. Compliance with Head-of-Bed protocols can also be performed based on actual patient position instead of being inferred from bed elevation angle.

  • Patent number: 11014125
    Abstract: Guards for a space access device are configured to be attached to, as well as removed from the space access device by hand, without the need to resort to any tools to perform the attachment or the removal. A distal guard includes at least first and second filters separated by at least one convoluted pathway, and also includes outwardly extending members projecting outwardly from a base of the distal guard. A proximal guard forms at least one convoluted pathway with a cap forming a proximal end of the space access device. A pull tab provides redundancy against failure. The pull tab may be incorporated into the distal guard.

  • Patent number: 10888251
    Abstract: A method is provided for automatically determining the status of a wearable sensor device configured to be worn by a user. The wearable sensor device includes at least one accelerometer that generates device acceleration data indicating an acceleration of the sensor device. The device acceleration data is used for both (a) a sensor device attachment analysis and (b) a turn protocol compliance analysis. The sensor device attachment analysis includes comparing the device acceleration data to stored reference data, determining an attachment or position status of the sensor device with respect to the user based on the comparison, and generating a corresponding alert notification. The turn protocol compliance analysis includes monitoring an orientation of the user based on the device acceleration data, comparing the monitored user orientation to at least one turn parameter defined by a turn protocol, and generating a turn protocol alert notification based on the comparison.
