Devices and techniques associated with diagnostics, therapies, and other applications, including skin-associated applications

摘要: The present invention generally relates to devices and techniques associated with diagnostics, therapies, other applications, including skin-associated for example, delivering and/or withdrawing fluid from subjects, e.g., through the skin. In some embodiments, device includes a system accessing an extractable medium skin of subject at access site, pressure regulator supported by support structure, able create differential across least portion site. may also include, in cases, sensor structure determining one condition subject, optionally signal generator generating relating determined sensor.
