Abstract
In some embodiments, a wound dressing includes at least one motion sensor for sensing a motion related parameter associated with motion of the wound dressing; and at least one further sensor for sensing a healing related parameter associated with wound healing at a region of tissue of a wound or proximate a wound covered by the wound dressing.
Claims20
An apparatus comprising:
- a wound dressing comprising a wound cover and a wound facing portion configured to be placed over a skin wound;
- a sensor patch releasably connected to a lateral side of the wound dressing, the sensor patch comprising at least one motion sensor configured to sense a motion related parameter associated with motion of the wound dressing;
- at least one further sensor configured to sense a healing related parameter associated with wound healing at a region of tissue of the wound or proximate the wound covered by the wound dressing;
- and
- a processor configured to:
- determine a sample period;
- determine that an output of the at least one motion sensor during the sample period satisfies a predetermined condition corresponding to a rate of acceleration of the wound dressing which is less than a predetermined rate of acceleration;
- and
- in response to determining that the output of the at least one motion sensor during the sample period satisfied the predetermined condition, determine the healing related parameter based on an output of the at least one further sensor during the sample period.

A wound monitoring method comprising:
- determining a sample period;
- sensing a motion related parameter associated with motion of a patient and a healing related parameter associated with wound healing at a region of tissue of the patient at or proximate to a skin wound, at least one of the motion related parameter or healing related parameter being sensed with a wound dressing comprising a wound cover, a wound facing portion configured to be placed over the wound, and a releasable sensor connected to a lateral side of the wound dressing;
- determining that the sensed motion related parameter satisfies a predetermined condition corresponding to a predetermined amount of motion of the patient;
- and
- storing, transmitting, or storing and transmitting data which represents the sensed healing related parameter associated with wound healing.

An apparatus comprising:
- a wound dressing including a wound cover and a wound facing portion configured to be placed over a skin wound on a patient;
- at least one motion sensor configured to sense a motion related parameter;
- at least one further sensor configured to sense a healing related parameter associated with wound healing at a region of tissue of the wound or proximate the wound covered by the wound dressing;
- and
- a processor configured to process an output of the at least one motion sensor, an output of the at least one further sensor, or both, the processor further configured to:
- set a sample period;
- determine if the output of the at least one motion sensor satisfies a predetermined condition corresponding to a predetermined amount of acceleration of the patient or the portion of the patient comprising the region of tissue is below a threshold value;
- in response to determining that the output of the at least one motion sensor satisfies the predetermined condition, retain data corresponding to the output of the at least one further sensor;
- and
- in response to determining that that output of the at least one motion sensor fails to satisfy the predetermined condition, discard the data corresponding to the output of the at least one further sensor,
- wherein the at least one motion sensor and the at least one further sensor are positioned on a separate portion releasably connected to a lateral side of the wound dressing.
