A power supply unit of an aerosol generating device includes: an accommodating portion with a bottom and cylindrical shape, which is configured to accommodate a columnar cartridge that stores an aerosol source in a state in which the cartridge is rotatable 360 degrees in a circumferential direction of the cartridge. A rotation suppressing portion configured to generate a frictional force between the cartridge and the rotation preventing portion so as to suppress rotation of the cartridge in the circumferential direction is provided on a bottom portion of the accommodating portion.

A sublingual type medication delivery device includes a container body having a predetermined volume of solvent with a spray dispenser attached at one end of the container and at the opposite end of the container is a housing which contains medication to be discharged into the container and mixed with the solvent to form a diluted medication for fractional delivery of the medication over a period of time. The housing can either be a tablet crusher for introducing medicament in solid form into the container or the housing can be a capsule having liquid medicament that is delivered through a needle that pierces the capsule wall.

A substance delivery device and methods to promote treatment regimen compliance. A beneficial substance and an addictive substance are administered from a device delivering the substances by a user inhaling vaporized or atomized beneficial substances and addictive substances.

An aerosol-generating device includes: a housing having a liquid storage cavity for accommodating an aerosol-generating substrate; a metal element arranged outside the liquid storage cavity; a static electricity generating assembly including a positive terminal and a negative terminal, one of the positive terminal and the negative terminal being electrically connected to the metal element so as to cause a part of the aerosol-generating substrate that is close to the metal element in the liquid storage cavity to be charged by electrostatic induction when the static electricity generating assembly is electrified; and a vaporization sheet, that, when electrified, vaporizes the charged aerosol-generating substrate to generate a charged aerosol.

A nasal delivery device for and a method of delivering substance to a nasal airway of a subject, the nasal delivery device comprising: a mouthpiece (519) through which the subject in use exhales to cause closure of the oropharyngeal velum of the subject; a nosepiece (517) for fitting to a nostril of a subject, the nosepiece including a nozzle (549) through which substance is in use delivered to the nasal airway; and a manually-actuatable substance supply unit (520) for delivering substance through the nozzle of the nosepiece.

A MEMS switch is actuatable by a fluid, and includes a piezoelectric pressure sensor that detects the movement of a fluid generating a negative pressure. The piezoelectric pressure sensor is formed by a chip of semiconductor material having a through cavity and a sensitive membrane, which extends over the through cavity and has a first and a second surface. The piezoelectric pressure sensor is mounted on a face of a board having a through hole so that the through cavity overlies and is in fluid connection with the through hole. The board has a fixing structure, which enables securing in an opening of a partition wall separating a first and a second space from each other. The board is arranged so that the first surface of the sensitive membrane faces the first space, and the second surface of the sensitive membrane faces the second space.

The present disclosure relates to drug administration. In an exemplary embodiment, a system can include a drug administration device configured to dispense a drug to a patient, a monitoring device configured to log a delivery event of drug delivery from the drug administration device into the patient, and a sensor configured to sense a patient parameter following delivery of the drug into the patient. In another exemplary embodiment, a drug administration device can include a drug holder configured to hold a drug, a dispensing mechanism configured to dispense the drug, and a sensor configured to sense a patient parameter, and the drug administration device can be configured to locally activate the drug at a target location in the patient. In another exemplary embodiment, methods, devices, and systems are provided to assess when operation of a drug dispensing mechanism is complete and to confirm whether drug administration was successful.

A multi chamber syringe unit includes a longitudinal body with side wall, distal end side, proximal end side opposite to distal end side, an interior limited by side wall between distal end side and proximal end side and distal opening arranged in distal end side for providing a liquid out of the body. The syringe further includes a separating element arranged in the interior of the body such that distal chamber and proximal chamber are formed in the interior of the body, wherein the separating element seals the distal chamber from the proximal chamber. The syringe has a bypass arrangement provided in the side wall of distal chamber of the body. A first pharmaceutical liquid is arranged in distal chamber of the body and second pharmaceutical liquid in proximal chamber of the body. The multi chamber syringe unit allows for adequately administering plural pharmaceutical liquids by injection.
