The invention relates to a wound dressing in which sensor technology can be integrated for detecting wound data such as pH value, moisture and temperature as well as data relating to the condition of the wound dressing itself.

A system for monitoring a wound includes a wound dressing configured to cover a wound surface of the wound, one or more sensing devices attached to the wound dressing, a network interface hardware, and a controller. The controller includes one or more processors, and one or more memory modules storing computer readable and executable instructions. The controller receives data measured by the one or more sensing devices, determines whether an infection is likely to occur based on the data measured by the one or more sensing devices, and outputs an alert, through the network interface hardware, in response to determining that the infection is likely to occur.

A bandage sensory member for monitoring temperature differences is disclosed. The bandage sensory member comprises a sensory layer having a plurality of temperature sensors disposed thereon, and a chip unit directly or indirectly electrically connected to the temperature sensors. The chip unit is configured to detect the temperature of each of the temperature sensors and send a wireless signal to an external receiver. The wireless signal contains information about the temperature difference and/or maximum temperature difference between the temperature sensors.

A sensor unit for detecting a pressure applied to a patient by a medical dressing, the sensor unit comprising: an electronic sensor configured to detect a pressure or force applied to a pressure plate of the electronic sensor; a plurality of lever elements positioned over the pressure plate, wherein each of the plurality of lever elements comprises an abutment region that is moveable towards the pressure plate; and, an exterior plate coupled to the plurality of lever elements such that, in use, a displacement of the exterior plate from an equilibrium position towards the pressure plate causes the abutment region of at least one lever element to move in a direction towards the pressure plate and transfer a force from the exterior plate to the pressure plate.

The invention comprises a method for monitoring a wound site of a patient, comprising the steps of: (1) applying a force to a breakable barrier of a bandage, applied to the wound site, to activate a time sensor at an initial time of application of the bandage; (2) monitoring elapsed time since application of the bandage through total migration length of a fluid from a reservoir into a migration zone; and (3) demarking time through progression of a colored fluid from the reservoir into the migration zone with calibrated time points printed on the bandage, such as in a PICC line assembly. Optionally and preferably, the breakable barrier is breached through a force of any of: applying a downward signing force across a frangible seam, peeling an adhesive backing off of the bandage, stretching an adhesive tape used to secure the PICC line, and rotating a valve.

A wound treatment system includes a housing that defines an oxygen outlet. An oxygen production subsystem is included in the housing and coupled to the oxygen outlet. A control subsystem is coupled to the oxygen production subsystem and configured to receive pressure information that is indicative of a pressure in a restricted airflow enclosure that is coupled to the oxygen outlet. The control subsystem then uses the pressure information to control power provided to the oxygen production subsystem in order to control an oxygen flow that is created by the oxygen production subsystem and provided through the oxygen outlet to the restricted airflow enclosure.

A conformable pressure sensor pad 109 comprising: a sensor arrangement 130 comprising a central column 10 of segments and outer columns 11 of segments, wherein the segments in the outermost columns are tapered outwardly, and wherein a pressure-sensitive sensor 22 is mounted in a plurality of the segments in the central column; and a conformable pad 110 including a plurality of pouches 62, the pouches 62 being in fluid communication with each other, each segment 10, 11 of the sensor arrangement 130 being positioned on a respective pouch 62, the plurality of pouches 62 being shaped to be positioned between a respective segment 10, 11 and the skin surface of a patient in use.

A securement device for an infant including a lower layer having a silicone adhesive and a center opening configured to receive an umbilical cord of the infant. An upwardly extending first securement tab and an upwardly extending second securement tab are positioned on opposing sides of the center opening. The first securement tab and the second securement tab define a bridge capturing an umbilical line. The lower layer includes a first antimicrobial, and the first securement tab includes a second antimicrobial.

A metabolite detection apparatus includes: a sensing module includes a sensing unit, a signal conditioning chip and a first coil sequentially connected, wherein the sensing unit is used for sensing a metabolite and generating a plurality of corresponding sensing signals, and the signal conditioning chip is used for processing the sensing signals to respectively generate corresponding conditioning signals, and transmitting a plurality of conditioning signals to the first coil for sending; and a processing module including a second coil and a data processing unit connected to each other, wherein the second coil is electromagnetically coupled and connected to the first coil to wirelessly transmit energy and data, the second coil is used for receiving the plurality of conditioning signals and transmitting the plurality of conditioning signals to the data processing unit, and the data processing unit is used for acquiring metabolite information according to the plurality of conditioning signals.

A wound covering includes chemical sensor within a detecting temperature and pH at the skin surface. Changes in temperature and changes in pH at the wound surface are communicated by providing modifications to the visual indicia. The combination of either a change in temperature, a change in pH, or both provide a changing visual indicium that can communicate to the bandage wearer, or a medical caregiver, that a need to change the dressing and/or treating of the wound is in order. The visual indicia may be expressed as a change in color, or a change in the shade of a color that is located at or transmitted to the outer surface of the wound covering. The condition of a wound may be determined without the need to undress the wound for visual inspection.
