摘要:
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.

Headbands configured to provide pressure against a medical sensor secured to a patient's forehead are provided. The headbands may include one or more low friction materials to enable an elastic band of a tensioning mechanism to evenly stretch. Additionally or alternatively, the headbands may include two or more bands adapted to secure the headband to various portions of a patient's head. Still further, the headbands may be configured to independently vary the pressure created between two or more sensors and the patient's head.

Systems and methods for measuring a physiological parameter of tissue in a patient are provided herein. In a first example, tissue interface pad for applying optical signals to tissue of a patient is provided. The tissue interface pad includes a first surface configured to interface with the tissue of the patient and further includes a first guide channel disposed generally parallel to a second guide channel. The first guide channel is configured to route an input optical fiber to a first location and optically couple an end of the input optical fiber to the tissue at the first location. The second guide channel is configured to route an output optical fiber to a second location and optically couple an end of the output optical fiber to the tissue at the second location.

Embodiments of the present disclosure relate to sensors for applying pressure to a patient's tissue. According to certain embodiments, the sensors may include one or more deformable elements that hold the optical components of the sensor against the tissue with an appropriate amount of pressure. In additional embodiments, such sensors may include a rigid one-piece sensor body that incorporates a deformable element to facilitate fine-fitting of the sensor against the tissue.
摘要:
Systems and methods for applying optical signals into tissue of a patient are provided herein. In one example, a tissue interface pad for applying an optical signal to tissue of a patient is provided. The tissue interface pad includes a first surface configured to interface with the tissue of the patient, at least one guide channel disposed within the tissue interface pad and configured to route an input optical fiber carrying the optical signal to a first location in the tissue interface pad, and a second surface at the first location configured to direct the optical signal from the input optical fiber into the tissue through the first surface.
