摘要： 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.

摘要： A system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.

摘要： In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

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, a system may comprise a tissue interface adapted to be coupled to a source of instillation fluid and a dressing interface having a therapy cavity that includes a pH sensor, a humidity sensor, a temperature sensor, and a pressure sensor embodied on a single pad within the dressing interface to provide data indicative of acidity, humidity, temperature and pressure at the tissue site. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage conditions as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise disposing the tissue interface at the tissue site and the therapeutic cavity in fluid communication with the tissue interface. The method may further comprise instilling fluid to the therapy cavity and then sensing the pressure, humidity, temperature, and the pH of the fluids adjacent the tissue interface. The method may further comprise determining various flow characteristics of the system by using a processing element electrically coupled to the sensors for transmitting property signals from the sensors to a controller configured to assess the property signals in order to identify the flow characteristics.
