Systems and methods for renal insufficiency treatment that include identifying and associating a solution container with a container support in the systems and methods are described herein. The systems and methods may associate an identified solution with an identified container support and verify compatibility of that combination with a selected treatment to reduce the likelihood for errors during setup and use of the systems and methods.

An electronically actuated droplet delivery device includes a housing with a removable mouthpiece that provides a level of air resistance and is interchangeable with alternative mouthpieces that provide alternative levels of air resistance. The level of air resistance can be customized to a particular user of the droplet delivery device by using air resistance elements having different sizes and/or numbers of openings that correspond to different internal air resistance for a droplet deliver device.

The present invention provides an inhalation device with which it is possible to improve usability and promote users' safety and satisfaction with the inhalation device. An inhalation device according to the present invention is provided with a first member and a second member which is configured to be capable of being attached to and detached from the first member. This inhalation device includes: an active functional part which is provided to the first member; a passive functional part which is provided to the second member and which is capable of changing the state thereof according to the working of the active functional part; a sensor part which is provided to the first member and which detects a changed state of the passive functional part; and a control part which, on the basis of the detected state, determines whether the second member has been attached to the first member.

An electronic droplet delivery device includes a housing including a mouthpiece located at an airflow exit side of the housing, a fluid reservoir, an aperture plate having a plurality of openings that receives fluid from the reservoir, an electronic actuator that oscillates the aperture plate to generate an ejected stream of droplets, and an ejector closure that opens and closes to help seal and prevent evaporation from the aperture plate when the droplet delivery device is not being used.

Systems and methods for automatically delivering medication to a user. An automated drug delivery system may include a sensor and a wearable automated drug delivery device. The wearable automated drug delivery device may be configured to couple to the skin of a user and may include a controller and a pump. The pump may be configured to output the medication. The controller may be within the wearable automated drug delivery device. The sensor may be coupled to the user and may be configured to collect information regarding the user. The controller of the wearable automated drug delivery device may use the collected information to locally determine an amount of medication to be output from the wearable automated drug delivery device and cause delivery of the amount of medication.
