  • Patent number: 11998340
    Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Patent number: 6504100
    Abstract: A reversible wire management system includes a mounting bracket having first and second planar members, the first and second planar members each including a set of retention bracket mounting features, wherein each set of retention bracket mounting features includes at least one mounting feature, which may be a slot, for connecting the respective planar member to a retention bracket, and at least one retention bracket, which may be a bifurcated O-ring, removeably attached to the first mounting bracket planar member using the first set of retention bracket mounting features, wherein the at least one retention bracket is adaptable to be selectively removed and reconnected to the second mounting bracket planar member using the second set of retention bracket mounting features.
