An apparatus for presenting an application status of a medical device that has a unused state and a used state. The apparatus includes a label having an electrochromic element. The label is at least partially disposed on an exterior surface of the medical device and is configured to display a predetermined feature in response to an electric current. A power source is disposed in or on the medical device for providing the electric current. A switch is configured to selectively connect or disconnect the label and the power source to one another for controlling the application of the electric current to the electrochromic element in response to actuation of the medical device from the unused state to the used state. The label may be scanned by a scan device that may connect to a medical organization for communicating information between the scan device and the medical organization.

A method of detecting and/or tracking use of a drug delivery device is disclosed. The drug delivery device includes a machine readable code and a visual indicator, and has pre-use and used states, such that use of the drug delivery device triggers a transition from the pre-use to the used state. The visual indicator has a first state when the drug delivery device is in the pre-use state and a different second state when the drug delivery device is in the used state. The method includes enabling a user device having an image sensor to capture an image of the drug delivery device, determining, by the user device processor from the captured image, whether the visual indicator of the drug delivery device is in the second state, and obtaining, by the processor, information from the machine readable code when the visual indicator is determined to be in the second state.

The invention relates to an electronic add-on module which is fitted releasably onto an automatic injection appliance before the start of injection. The add-on module comprises a force sensor for measuring a time-variable axial force component exerted on or transmitted to the attached add-on module by the injection appliance during an injection procedure. The add-on module also comprises a grip or a preferred grip position for gripping and holding the add-on module and the inserted injection appliance. The add-on module can additionally have a microphone for detection of acoustic signals. A state of the injection appliance can be determined by the add-on module solely on the basis of measurements of the axial force sensor, optionally supplemented by microphone measurements. The invention thus affords a straightforward and cost-effective way of monitoring or controlling the correct performance of an injection procedure carried out with an automatic injection appliance.

A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

An infusion pump system may include a portable infusion pump configured to be worn by a user and a separable display. The portable infusion pump may include a fluid container configured to store a fluid to be delivered to the user, a pumping mechanism configured to drive the delivery of the fluid from the fluid container to the user via a fluid delivery tube, and communications circuitry. The separable display may transmit, to the communications circuitry of the portable infusion pump when the separable display is coupled to the portable infusion pump, a fluid delivery protocol. The separable display may be separated from the portable infusion pump after transmission of the fluid delivery protocol to the portable infusion pump.

In some embodiments, an adjunct device for tracks time and/or dosage of a medicine. The device may include a connector for mounting the device to a deposable pen injector. The device may be configured to allow use of the native controls and injectors of the injector. For example the device may include a view port for viewing a dose indicator of the injector. The device may include one or more vibration sensors. A processor may be configured to differentiate increasing a dose, decreasing a dose and/or discharging the medicine based on the output of the sensors. Optionally a display of the device may be positioned for simultaneous viewing with the dosage indicator of the injector. For example a user may verify the accuracy of the adjunct device before performing a discharge.

Disclosed is a method for selecting a suitable inhaler device to a user. The method comprises using a spirometer and a computer comprising a display. The method comprising the following steps: A) connecting the spirometer and the computer; B) the computer, or spirometer, indicating to the user to inhale through the spirometer; C) the spirometer sending flow over time data of the inhalation made to the computer; and D) the computer comparing the flow over time data with dose emission over time data for a range of inhalers and indicating the suitable inhaler from the range of inhalers as the inhaler with the largest dose emission within the flow over time data. Disclosed is also a system for establishing a suitable inhaler device. The system comprises a spirometer and a computer connectable to each other for data transfer. The spirometer or the computer is configured to indicate to the user to inhale through the spirometer. The spirometer is configured to send flow over time data of the inhalation made to the computer. The computer is configured to compare the flow over time data with dose emission over time data for a range of inhalers and indicating the suitable inhaler of the range of inhalers as the inhaler with the largest dose emission within the flow over time data.

A drug delivery device includes a housing, a reservoir, a cannula, one or more light sources, a label, and a controller. The reservoir is disposed within the housing. The cannula is connected to the reservoir for delivering a drug from the reservoir to the patient. The light sources are disposed adjacent the exterior surface of the housing, and each serves to indicate one of one or more operational conditions of the device. The label is fixed to the housing adjacent the light sources, and includes one or more informational messages. Each informational message is aligned with one of the light sources for conveniently conveying to a user an operational condition of the device as indicated by the corresponding light source. Finally, the controller is operably connected to the reservoir and the light sources. The controller is configured to actuate the reservoir to deliver the drug, and to selectively illuminate the one or more light sources based on the operational condition of the drug delivery device.
