Abstract: According to various embodiments, a medical monitoring system includes an extension cable for connecting a medical monitoring device to a sensor cable of a sensor. The extension cable includes a head for accepting a plug of the sensor club, wherein the head includes a lid for restraining the plug within an port of the head of the extension cable. Further, the head includes a hinge configured to allow the lid to rotate about the hinge, wherein the hinge is located within the head such that the head includes substantially flat outer surfaces.

Abstract: Various embodiments of tracheal tube assemblies disclosed herein may include a tubular body having an open distal end for ventilating a patient and a cuff disposed around the tubular body above the open distal end. The cuff may be adapted to be inflated to seal the cuff against a wall of a trachea of the patient. The cuff may include a first portion that spaces the tubular body a first distance from the tracheal wall when inflated and a second portion that spaces the tubular body a second distance from the tracheal wall when inflated. The second distance may be greater than the first distance.

Abstract: According to various embodiments, methods and systems for determining pressure in the lungs may employ tracheal pressure measurements. The tracheal pressure measurements may be obtained through a pressure monitoring lumen associated with a tracheal tube. Such systems may include a purging or flushing mechanism to keep the pressure monitoring lumen free of any obstructions. The flushing mechanism may utilize fluids delivered through the pressure monitoring lumen at a predetermined point in the breathing cycle and/or at a predetermined pressure relative to the respiratory gases. The resulting pressure measurements may be used to determine a more accurate estimate of lung pressure, which in turn may be used to control a ventilator and provide breathing assistance to a patient.

Abstract: According to various embodiments, methods and systems for determining pressure in an inflatable cuff of a tracheal tube may employ pressure transducers associated with a cuff inflation line or a pilot balloon assembly. The pressure transducers may be implemented to provide continuous or intermittent cuff pressure. Also provided are tracheal tubes with adapters or other devices that incorporate pressure transducers. The tracheal tubes may facilitate wireless cuff pressure monitoring.

Abstract: An indicator dilution system includes a catheter configured to deliver an indicator to a patient, an injection device configured to deliver the indicator to the catheter, and a connector coupling the injection device to the catheter. The system also includes one or more sensors configured to acquire measurements from components of the system, which may be used to determine the start and end time of the injection of the indicator to the patient. For example, the one or more sensors may be configured to acquire signals relating to a state of the connector, which may be used to determine whether the connector is in an open state to enable flow of the indicator or in a closed state to reduce flow of the indicator.

Abstract: The present disclosure describes systems and methods that utilize a multi-lumen tube with an integral visualization apparatus, such as a camera. The multi-lumen tracheal tube system may include a camera apparatus that is positioned to facilitate left or right bronchial intubation. In addition, the camera apparatus may be a unitary assembly that functions to hold and position the camera relative to the tube and provides an acceptable profile for comfortable intubation. The camera apparatus may include additional components, such as integral light sources and flushing or cleaning devices to remove any buildup from the camera or optical components.

Abstract: Medical sensors configured to provide enhanced patient comfort when worn over a period of time are provided. The medical sensors may include a first padding layer and a second padding layer disposed on either side of an emitter and a detector for measuring a physiological parameter of a patient. The medical sensors may also include an island padding layer secured to a patient-facing side of the second padding layer for reducing localized pressure points that may be caused by protrusions of the sensor. Additionally or alternatively, certain edges of the sensors may be rounded and/or stepped to reduce marking on the patient's tissue and to reduce strain and shear forces produced on the patient's tissue. Still further, certain embodiments provide enhanced light transmission between the emitter and detector of the sensors.

Abstract: Various methods and systems for the use of capacitance sensors within medical devices configured for patient monitoring are provided. The capacitance sensors are configured to measure a change in capacitance resulting from a material (e.g., human tissue, water, gel, cloth, etc.) placed near (e.g., close proximity to) the medical device and/or resulting from a material making physical contact with the medical device. In certain embodiments, the capacitance sensor may be utilized to detect whether one or more portions of the medical sensor are securely applied to the patient's tissue (e.g., sensor “on”) and/or may be utilized to detect whether one or more portions of the medical sensor fail to maintain secure contact with the patient's tissue (e.g., sensor “off”). Further, in certain embodiments, the capacitance sensor may be utilized to distinguish between one or more types of materials (e.g., human tissue, water-based materials, etc.).
