Methods and systems for monitoring the status and usage of a metered dose inhaler (MDI) and communicating status, usage, and guidance information to a user of the MDI and to a mobile computing device are presented herein. An IMD includes a dosage dispense detection device, an accelerometer, and a visual transducer, an audio transducer, a haptic transducer, or any combination thereof. The dosage dispense detection device detects when a user applies a compressive force across the IMD. The accelerometer measures a shaking of the IMD by a user before self-administering a dose. The IMD determines whether the medicine is adequately shaken by the user, and if so, communicates an indication to the user that the pressurized canister of medicine is ready for dosage. In another aspect, the IMD communicates a sequence of indications that mark each transition of a dosage regimen plan to self-administer a dosage of medicine.

An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.

A drug delivery device that includes a housing. The housing contains a syringe, and the syringe includes a container containing a liquid medicament. The container includes an aperture at a distal end and through which the liquid medicament can be dispensed. The syringe includes a stopper within the container. The stopper is moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of the liquid medicament through the aperture. The syringe includes at least one identifying means identifying the liquid medicament.

An aerosol delivery device is provided that includes at least one housing structured to retain an aerosol precursor composition. The device includes an atomizer, and a microprocessor configured to operate in an active mode in which the control body is configured to control the atomizer to activate and produce an aerosol from the aerosol precursor composition. And the device includes a heart rate monitor including a plurality of biopotential electrodes affixed to the housing and configured to obtain biopotential measurements from a user, and including signal conditioning circuitry configured to produce an electrocardiogram signal from the biopotential measurements. The microprocessor is coupled to the signal conditioning circuitry and further configured to control operation of at least one functional element of the aerosol delivery device based on the electrocardiogram signal or a heart rate of the user calculated therefrom.

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device involves obtaining one or more measurement values of a physiological condition in the body of a user during an initial monitoring period and determining a fasting reference value for a metric based on the one or more measurement values. After the initial monitoring period, the method continues by obtaining an updated measurement value during a fasting period, determining a current value for the metric based at least in part on the updated measurement value, and generating a notification in response to a deviation between the current value and the fasting reference value exceeding a threshold indicative of insertion site loss or other loss of effectiveness.

Aspects of the present disclosure provide a smart relaxation mask configured to output a stimulus and collect biometric information while the stimulus is output to determine if the subject is paying attention to the stimulus. If the subject is not focused on the stimulus, the mask adjusts at least one of an audio, visual, or haptic output. The stimulus is adjusted in an effort to shift the subject's attention to the stimulus and away from racing thoughts.

A control device for a heart pump, comprising a device for establishing the end-diastolic filling pressure in a ventricle and a device for associating a delivery rate of the pump, in particular a pump speed or an electric pump capacity, with the established end-diastolic filling pressure. By taking into account the end-diastolic filling pressure, a robust operating option of the heart pump, similar to the physio-logical control, is created.

Blood glucose control systems are disclosed. A blood glucose control system can receive a glucose level signal from a glucose sensor operatively coupled to a subject. The system can decode encoded data of the glucose level signal to obtain the glucose level of the subject and the indication of the glucose trend. The system can automatically calculate the dose control signal using a control algorithm configured to calculate regular correction boluses of glucose control agent in response to at least the glucose level of the subject. The system can select a dose control signal encoding profile from a plurality of dose control signal encoding profiles and, based on the dose control signal encoding profile, encode the dose control signal such that the pump controller can read the dose control signal. The system can transmit an encoded dose control signal to the pump controller.

In various embodiments, a caregiver module is provided for use with a patient medical device, including a sensor to obtain a sensor signal related to the use of the patient medical device; an analog-to-digital converter to convert the sensor signal to corresponding sensor data; and a controller to transmit the sensor data to a wearable device, wherein the sensor data is transmitted in the same form as created by the converter. Various embodiments provide a wearable device for processing sensor data received from the caregiver module, including: memory storing processing instructions for interpreting sensor data of multiple types; and a processor to: receive configuration information associated with the caregiver module, receive sensor data of a first type from the caregiver module, and execute the processing instructions based on the configuration information, wherein the configuration information alters the operation of the processing instructions to interpret sensor data of the first type.

Systems and devices for an updatable blood pump are disclosed herein. The blood pump can be part of a mechanical circulatory support system that can include a system controller and the blood pump. The blood pump can include a rotary motor and a control unit that can communicate with the system controller. The system controller can initiate the update process and can provide the update to the blood pump. Upon initiation of the update process, the control unit can stop the rotary motor. While the rotary motor is stopped, the blood pump can be updated. At the completion of the update, the rotary pump can be restarted.
