A system, method, and apparatus are disclosed for dressing a wound. The apparatus comprises a liquid and gas permeable transmission layer, an absorbent layer for absorbing wound exudate, the absorbent layer overlying the transmission layer, a gas impermeable cover layer overlying the absorbent layer and comprising a first orifice, wherein the cover layer is moisture vapor permeable.

A connector having a connector body with an inlet and an outlet defining a gas flow passage therebetween. The connector body has an overlap portion that is configured to overlap with a portion of a second connector when connected. An access passage extends through the overlap portion to the gas flow passage.

A method includes receiving a pressure signal from a pressure sensor and/or a flow signal from a flow sensor and receiving signals from one or more sensors that measure different physiological parameters from the pressure sensor and the flow sensor. The method includes detecting the onset of the spontaneous breath by the patient based on the pressure signal and/or the flow signal and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the pressure signal and/or the flow signal. The method includes calibrating parameters and thresholds to be utilized in detecting the onset of the spontaneous breath based on the signals. The method includes after calibration, switching to: detecting the onset of the spontaneous breath by the patient based on the signals and synchronizing providing breathing support to the patient with the onset of the spontaneous breath detected utilizing the signals.

Systems and methods for reducing pathogens near an implant are discussed. In some cases, the methods include reducing contaminants in a portion of a patient that has an implant and that is disposed interior to a closed surface of skin of the patient. The method can further include placing a conduit in the closed surface of skin and flowing an antimicrobial fluid into that portion of the patient to contact the antimicrobial fluid with a surface of the implant and tissue adjacent to the implant. In some cases, the antimicrobial fluid is then removed from the portion of the patient having the implant. As part of this method, biofilm near the implant can be mechanically, ultrasonically, electrically, chemically, enzymatically, or otherwise disrupted. Other implementations are described.

The present disclosure is directed to an insufflator which includes a controller, an insufflation line, a desufflation line, and one pressure sensor and one volume flow sensor associated with each of the insufflation and desufflation lines. The insufflation line is in fluid communication with a gas source and the desufflation line in fluid communication with a suction pump. Wherein the controller controls ventilation of a gas present in patient by adjusting an amount of suction in the desufflation line as a function of pressure measurements obtained from the pressure sensors associated with the insufflation and desufflation lines. Additionally, the controller includes an activation blocking system that prevents suction in the desufflation line when a pressure measured by means of the pressure sensor associated with the insufflation line is lower than a preset threshold value. Still further, the activation blocking system further prevents suction in the desufflation line when the pressure measured by means of the pressure sensor associated with the insufflation line and a pressure measured by means of the pressure sensor associated with the desufflation line are not identical.
