A removable base of a wearable medical monitor includes a mating surface configured to reversibly couple the removable base to a body of the wearable medical monitor. The removable base may also include certain functional features, such as a sensor configured to detect a physiological parameter of a patient and/or a memory configured to store data for identifying characteristics of the sensor or the patient.

Removable base for wearable medical monitor

Embodiments of the present disclosure relate to reusable medical sensors. According to certain embodiments, the medical sensor may include a sensor housing, an emitter disposed in the sensor housing, the emitter being configured to direct light through the tissue of a patient, and a detector disposed in the sensor housing, the detector being configured to detect light from the emitter after the light has passed through the tissue of the patient and to convert the detected light to an electrical signal. The sensor may also include a dye disposed in the sensor housing, wherein the dye is configured to exit the sensor housing when the sensor housing is damaged and is within a solution.

Reusable wireless medical sensors

A physiological monitoring system may receive a sensor signal from a physiological sensor. The system may determine a parameter based on the sensor signal, for example variability of a blood oxygen saturation value or the percent modulation of a light signal. The system may determine a light drive parameter limit based on one or more parameters. For example, the system may determine a light drive current limit. The frequency of changes in the limit may be regulated using a state machine and other techniques that include hysteresis. An extant light drive parameter may be updated or changed in accordance with the light drive parameter limit and a light drive signal may be generated based on the light drive parameter.

Methods and systems for determining a light drive parameter limit in a physiological monitor

The present disclosure relates generally to medical devices and, more particularly, to medical devices with electrical connectors. In one embodiment, a medical device may include a medical connector having one or more contacts configured to enable communication between the medical device and a medical monitor according to a Universal Serial Bus (USB) standard. The medical connector may also include an interface region disposed at least partially about the one or more contacts. The interface region may be configured to physically couple to a mating connector of the medical monitor. Additionally, the interface region may include a geometry or a dimension that does not comply with the USB standard.

Medical device with electrically isolated communication interface

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. These cuffs may include features that facilitate detection or visualization of the cuff, for example with ultrasound devices, to ensure proper placement of the cuff and the tube. Such surface features may include particular types of materials or shaped or protruding features that may be detected in the environment of the trachea.

Ultrasound-based tracheal tube placement device and method

A surgical system configured for treating tissue is provided. The surgical system includes a laser source and a laser scalpel. The laser scalpel is adapted to couple to the laser source and is operable in two modes of operation, a first mode of operation to analyze tissue of interest and a second mode of operation to treat tissue of interest. The laser scalpel includes a housing having first and second fiber optic cables extending therethrough. Each of the first and second fiber optic cables operable under the first mode of operation to collect information pertaining to at least one optical property of tissue of interest and at least one of the first and second fiber optic cables also operable under the second mode of operation to treat the tissue of interest.

Surgical system and method of use of the same

According to various embodiments, a regional oximetry sensor may include a light emitting element configured to emit light, a light detector configured to receive the light, and a memory device configured to store a baseline. The baseline stored by the memory device enables a regional oximetry monitor to display the baseline on a display of the regional oximetry monitor.

System and method for storing and providing patient-related data

Embodiments of the present disclosure relate to reusable wireless sensors. According to certain embodiments, the wireless sensor may include a rechargeable battery coupled to an induction coil for recharging the battery. One or more magnets may be disposed within or coupled to the wireless sensor, and the one or more magnets may be arranged to align the induction coil of the wireless sensor with a recharging device to facilitate recharging the battery of the wireless sensor.

Embodiments of the present disclosure relate to techniques for controlling the temperature of light sources within physiological sensors in order to regulate the wavelengths emitted by the light sources. The sensors may include a temperature control element that is designed to provide heating and/or cooling to the light sources. The sensors also may include a temperature sensor designed to detect the temperature of the light sources. Based on the detected temperature, a controller can vary the amount of heating and/or cooling provided by the temperature control element to maintain the temperature of the light sources at a desired temperature or within a desired temperature range.

Medical sensor with temperature control

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.

Medical sensor for use with headband

The present disclosure describes systems and methods that use spatial modulation to focus continuous wave light into a localized region of interest such as an individual blood vessel. In certain embodiments, intensity modulation techniques, such as linear frequency modulation, are used in conjunction with spatial modulation to achieve more precise measurements through otherwise scattering medium. The focused beam of continuous wave light is capable of penetrating several centimeters of tissue to deliver measurements and images associated with individual blood vessels and other discrete vascular components.

Light focusing continuous wave photoacoustic spectroscopy and its applications to patient monitoring

According to various embodiments, a tracheal tube may employ optical sensing techniques for determining a distance between the inserted tube and an anatomical structure, such as a carina. The distance information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. The optical techniques may include backscattered intensity measurements.

Method and system for determining placement of a tracheal tube in a subject

According to various embodiments, a tracheal tube may employ optical sensing techniques for determining an orientation of the inserted tube in a subject. The orientation information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. The optical techniques may include interferometry.
