An image coding method includes: performing context arithmetic coding to consecutively code (i) first information indicating whether or not to perform sample adaptive offset (SAO) processing for a first region of an image and (ii) second information indicating whether or not to use, in the SAO processing for the first region, information on SAO processing for a region other than the first region, the context arithmetic coding being arithmetic coding using a variable probability, the SAO processing being offset processing on a pixel value; and performing bypass arithmetic coding to code other information which is information on the SAO processing for the first region and different from the first information or the second information, after the first information and the second information are coded, the bypass arithmetic coding being arithmetic coding using a fixed probability.

Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise positioning a dressing interface having a pH sensor, a temperature sensor, a humidity sensor, and a pressure sensor at a tissue site, and applying reduced pressure to the dressing interface to draw fluids from the tissue interface in contact with the sensors to sense the pH, temperature, humidity, and pressure properties of the fluids flowing from the tissue site. The method may further comprise providing fluid data indicative of such properties to a processing element for processing the fluid data, and transmitting the data to another component in the system.

A smart bandage that serves as a functional bandage includes electronic components that allow the bandage to store large amounts of data. The components can include a processor, battery, data storage media, NFC components, Bluetooth components, and Wi-Fi components. The bandage can remain powered down until receiving an NFC signal, which then causes the bandage to power up its components and communicate using other wireless communications means. Healthcare data compression methods may be used to improve the information storage capabilities of the smart bandage.

A wound dressing includes a superabsorbent pad, a drape layer, a humidity chamber, a wick, and a humidity colorimeter sensor. The superabsorbent pad is configured to absorb wound fluid and has a first side and a second, wound- facing side. The drape layer is coupled to the first side of the superabsorbe nt pad and has a first side and a second, wound- facing side. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The humidity chamber is coupled to the first side of the drape layer opposite the superabsorbent pad. The wick extends through the drape layer and is configured to wick moisture between the superabsorbent pad and the humidity chamber. The humidity colorimeter sensor is located within the humidity chamber and configured to change color responsive to a humidity level within the humidity chamber.

A wound sensor comprising at least one electrode (10a, 10b) and a non-adherent porous layer (25) proximate at least part of the electrode.

The wound dressing described herein includes a backing layer, absorbent layer, and foam layer. The wound dressing also includes one or more visual indicators. The visual indicators are substantially non-visible in their initial, dehydrated state. As the visual indicators absorb fluid they swell and become visible. The visual indicators enable a caregiver to know when the wound dressing has reached, or is about to reach, its fluid capacity.

The present invention relates to a system and method for monitoring, capturing, storing, processing, and enabling remote access of a plurality of data inputs pertaining to wound therapy of one or more subjects. The system as per the present invention comprises a wearable dedicated monitoring device, one or more user devices, a digital platform, a subject consent management means. The monitoring device is configured to receive a plurality of data inputs captured from one or more subjects undergoing wound therapy. The plurality of data inputs comprises one or more functional parameters of wound therapy, one or more modalities for wound therapy, and one or more factors impacting wound therapy. A unique identifier code is assigned by the monitoring device to specifically link the plurality of data inputs to each subject. Each of the plurality of data inputs is time stamped and based on the specific consent of the subjects, the data inputs are communicated to the user devices and the digital platform. The digital platform is configured to store, process, correlate, and enable remote access to the data inputs.

A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.
