Title:
SYSTEMS AND METHODS FOR CONTROLLING NEGATIVE PRESSURE THERAPY USING PROPERTIES OF FLUIDS FROM A TISSUE SITE
Document Type and Number:
WIPO Patent Application WO/2019/140448
Kind Code:
A1
Abstract:
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.
