Described herein are an interactive apparatus and methods for sensing and measuring real-time characteristic patterns of a subject's use of a dry powder inhalation system. The inhaler device can be used in a wireless communication mode to communicate with a display to assess the subject's usage of the inhalation system concurrently as the inhalation is performed and thus the subject's inhalation can be evaluated as well as the performance of the inhalation system. The system can also detect the identity of the medicament, its dosage, lot, expiration, etc. and the characteristics profile of a dry powder formulation emitted from the inhalation system in use.

The present disclosure relates to medicament injection devices. An injection device includes: a movable dosage programming component comprising a rotary encoder system having a predefined angular periodicity, a sensor arrangement including a first optical sensor configured to detect movement of the movable dosage programming component relative to the sensor arrangement during dosing of a medicament, wherein the first optical sensor is configured to operate in a strobe-sampling mode at a first frequency, a second optical sensor configured to detect movement of the rotary encoder system relative to the second optical sensor wherein the second optical sensor is configured to operate in a strobe-sampling mode at a second frequency lower than the first frequency, and a processor arrangement configured to, based on the detected movement, determine a medicament dosage administered by the injection device.

Medical devices and related guidance systems and methods for interactive patient guidance are provided. An exemplary method of interactively providing guidance facilitating operation of a medical device involves identifying, at a computing device communicatively coupled to the medical device, a user objective associated with the medical device, obtaining, at the computing device from the medical device, user interface status information corresponding to a current state of a user interface of the medical device, and providing, on a display associated with the computing device, guidance information influenced by the user interface status information and the user objective. Subsequently, updated user interface status information for the infusion device responsive to a user input with respect to the infusion device may be provided to the computing device, with the guidance information being dynamically updated in response to the updated status information.

A respiratory system and method comprise a tracker module adaptable to be secured to a variety of inhalers, the tracker module sensing activation of the medication canister of the inhaler for delivery of medication to a user. The tracker module also senses the rate of inhalation air flow of the user when inhaling medication for determination of proper inhaler use. Upstream and downstream sensors provide flow information to determine quality of the inhalation. Other sensors are provided that monitor user presence at the inhaler, user technique in using the inhaler, and the attitude of the inhaler when it was used. Low power devices are used to conserve battery power.

The present disclosure relates to a medicament delivery device comprising: a reservoir for medicament; a dispensing mechanism operable to dispense medicament from the reservoir, the dispensing mechanism comprising a sleeve configured to rotate during the dispensing of medicament and having a plurality of formations at an end of the sleeve; and a dosage measurement system comprising at least one mechanically actuated sensor configured such that, in use, rotation of the sleeve causes successive formations to engage the sensor such that the sensor detects rotation of the sleeve and a processor configured to determine a dosage dispensed from the medicament reservoir based on the detected rotation of the sleeve.

A wireless data communication circuitry for a drug delivery device is disclosed, wherein the circuitry comprises a wireless communication processor for handling wireless data communication, a battery connector having a positive and a negative terminal, the positive terminal and the negative terminal being connected to respective terminals of the wireless communication processor for supplying the wireless communication processor with electrical energy from a battery connectable to the battery connector, and an arrangement of one or more capacitors, each one of the capacitors being connected in parallel to the positive terminal and the negative terminal of the battery connector and provided for backing up the supplying of the wireless communication processor with electrical energy from the battery connectable to the battery connector.

A method includes receiving data associated with a sleep session of a user. The method also includes determining that the user is experiencing or has experienced an event based at least in part on the data. The method also includes causing pressurized air to be directed from a respiratory device to a multi-compartment bladder in response to determining that the user is experiencing or has experienced the event to aid in modifying a position of a head of the user.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.

The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.
