CLOSED-LOOP CONTROL OF INSULIN INFUSION
Disclosed herein are devices, methods and systems for monitoring and detection of adverse events in a subject. In an embodiment, an insulin delivery device includes an insulin injection device in communication with a controller for controlling the insulin injection device. The controller is configured to receive a heart signal from one or more heart sensors, and a blood glucose signal from one or more blood glucose sensors. The controller is further configured to analyze changes in the heart rhythm of the subject based on the heart signal and determine, based on the changes in the heart rhythm and the blood glucose signal, whether the subject is and/or will be experiencing an adverse event. Upon determination that the subject is or will be experiencing an adverse event, the controller determines one or more parameters of delivery of insulin to be delivered to the subject. Finally, the controller is configured to control the injection device to deliver insulin to the subject in accordance with the determined one or more parameters of delivery.
WEARABLE DEVICE WITH BRIDGE PORTION
The present disclosure relates to a wearable device with a bridge portion and systems/methods relating to the device. Preferred embodiments may include two flexible wings and a bridge connecting the two wings. In some embodiments, the upper surface of the bridge can be non-adhesive and uncoupled to the flexible wing such that the flexible wing can be decoupled from the bridge when the adhesive is adhered to the surface of a user. The bridge can be narrower in some portions, and extend around the housing of the monitor. The bridge can extend beneath the housing and bisect the two flexible wings.
Method and device for measuring muscle signals
In order to determine the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state, a signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state. A mapping is used to improve accuracy of state determination, e.g. with a reference database.
SURFACE ELECTRODE FOR PATIENT MONITORING
A surface electrode for patient monitoring includes a flexible substrate, a dry electrode on the substrate, and a wet electrode configured to contact an electrode gel in contact with a patient's skin. A conductive epoxy is arranged between the dry electrode and the wet electrode. The conductive epoxy is configured to protect the dry electrode from corrosion and transfer electrical potentials from the wet electrode to the printed dry electrode.
