Reduced pressure therapy systems and methods for monitoring patient movement
According to certain embodiments, an apparatus for applying negative pressure to a wound can include a negative pressure source, a sensor, and a controller. The negative pressure source can be configured to couple via a fluid flow path to a wound dressing and provide negative pressure to the wound dressing. The sensor can be configured to monitor a magnitude or frequency of pressure in the fluid flow path generated by the negative pressure source. The controller can be configured to determine an activity classification, such as breathing, changing positions while lying, sitting, walking, standing, jumping, traversing stairs, leg extending, leg bending, and performing chair squats, based on a change in the magnitude of pressure over time while the negative pressure source maintains the magnitude of pressure in the fluid flow path below a negative pressure threshold. The controller can output an indication of the activity classification.
Sensor system
The disclosure relates to a sensor system for detecting a position of a movable plunger in a drug delivery device, the sensor system comprising a sensor capable of detecting a magnetic field, the sensor adapted to be fixed within a housing of a drug delivery device, and a ferromagnetic or permanent magnetic component magnetically interacting with the sensor and adapted to move relative to the sensor as the plunger is moved.
Articulating stylet
An articulating stylet usable with a tracheal intubation system is disclosed. Methods for using the articulating stylet and systems that incorporate the articulating stylet are also disclosed. In some examples, a stylet adapted for mounting an endotracheal tube comprises a shaft and a control wire. The shaft comprises a distal shaft portion, a proximal shaft portion, and an expanding connection joining the distal shaft portion to the proximal shaft portion. The proximal shaft portion has a body portion and a tip portion. The tip portion includes a tip and has greater flexibility than the body portion. The control wire is at least partially disposed within both the distal shaft portion and the proximal shaft portion and is configured to cause the tip portion of the proximal shaft portion to deform.
System and method for adjusting insulin delivery
The embodiments described herein may relate to methods and systems for adjusting insulin delivery. Some methods and systems may be configured to adjust insulin delivery to personalize automated insulin delivery for a person with diabetes. Such personalization may include adjusting user specific dosage parameters in response to one or more back-filled time segments associated with a diurnal time block.
Systems and methods for split bolus protocol generation
Described is an injector system for implementing a split bolus injection procedure. The injector system includes a processor and a non-transitory storage medium having programming instructions stored therein that, when executed by the processor, enable the injector system to operate as a parameter generation system for use in determining parameters associated with a split bolus injection protocol via which injection of the contrast agent by the injector system is controlled. The split bolus injection protocol includes at least a loading injection and a diagnostic injection, wherein the loading injection is performed before the diagnostic injection, and wherein a pause separates the loading injection from the diagnostic injection. Also described is a method for patient imaging using a split bolus injection technique and a system having an imaging device and the injector system described above.

Opioid overdose monitoring
An overdose of opioids can cause the user to stop breathing, resulting in death. A physiological monitoring system monitors respiration based on oxygen saturation readings from a fingertip pulse oximeter in communication with a smart mobile device and sends opioid monitoring information from the smart mobile device to an opioid overdose monitoring service. The opioid overdose monitoring service notifies a first set of contacts when the opioid monitoring information.
Event detection for drug delivery system
A drug delivery device may include an Inertial Measurement Unit (IMU) is provided. The IMU may include an accelerometer, a magnetometer, or a gyroscope. Motion parameters may be detected when the drug delivery device is shipped, being prepared for activation for use, or during use. The IMU may provide data indicative of a rapid deceleration, such as when a package containing the drug delivery device is dropped, or some other physical event experienced by the drug delivery device. The drug delivery device may also include internal or external pressure sensors or a blood glucose sensor that may coordinate with the IMU to provide additional feedback regarding the status of the device or user. A controller of the drug delivery device may generate a response depending on the particular parameters being monitored or may change device operational parameters as a result of detected system events.
Switched reluctance motor
A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.
