An information processing device provided with a control part, wherein the control part: generates a display image for displaying a profile that is information indicating time series variation in a parameter regarding an operation for generating an aerosol, the operation being performed by an inhalation device for generating the aerosol by using a base material; and modifies the profile and the display of the profile in the display image in accordance with the user operation with respect to the parameter to be operated in the generated display image.

A clotting agent delivery system comprises a frame, a passageway extending along the frame, a discharge opening connected to the passageway, a clotting agent reservoir fluidly connected to the passageway to hold a clotting agent substance, a valve in the passageway to control flow of the substance through the passageway, and an actuator to allow propellent to flow into the passageway, wherein the valve and clotting agent reservoir cooperate to provide clotting agent substance to the discharge opening at constant pressure using the propellant. A method for delivering a clotting agent comprises inserting a delivery catheter into an anatomic area, coupling a clotting agent delivery system to the delivery catheter, the clotting agent delivery system having a reservoir of a clotting agent, operating a valve to release propellant for propelling the clotting agent, and conveying the propellant and the clotting agent to the delivery catheter at a constant pressure.

A substance delivery mask includes a body, an exhaling valve, an inhaled valve, and a fog module. The fog module comprises a controlling module, a container, and an atomizer. The controlling module is disposed on the body. The container is disposed on the controlling module, the container is storing a mixed liquid, and the mixed liquid includes water and a plurality of nanoparticles. The atomizer is disposed on the container, the atomizer is used to atomize the water of the mixed liquid to form fog particles, and the fog particles are wrapped several of the nanoparticles respectively. The substance delivery mask can encapsulate the water-soluble or water-insoluble medicines, or nutritional products in the fog particles generated from the atomizer. The present invention can deliver medicine, nutritional products or vaccines by inhalation or oral.

A needle assembly for pleural space insufflation is disclosed. The needle assembly has an outer shaft defining one or more pliable tissue receivers. The needle assembly also has a needle moveable within the outer shaft from a retracted position to an engaged position that does not extend past a distal end of the outer shaft. A method of pleural space insufflation is also disclosed. A parietal pleura is contacted with a distal end of an outer shaft that defines one or more pliable tissue receivers. The distal end of the outer shaft is pushed against the parietal pleura so that a portion of the parietal pleura enters the one or more pliable tissue receivers. A needle is advanced within the outer shaft so that the needle pierces the parietal pleura.

Methods and apparatuses for the therapeutic delivery of nicotine for smoking cessation, harm reduction and/or substitution. Furthermore, the devices and methods herein are useful as an alternative, general nicotine delivery system in place of tobacco combustion or high temperature (over 150 degrees C.) products. In addition, the methods and devices herein are useful for the therapeutic delivery of a drug, for reducing the cumulative drug dose and hence its potential toxic side effects, while increasing its neurophysiological and/or physiological effects. Moreover, the devices and methods herein are useful for addiction treatment or reduction. In certain embodiments, the methods are adaptable to a medicament delivery device that determines a sequence of drug doses to be delivered. Dose information may be used to control operation of the device.

Systems and methods for monitoring an operational state and/or a fill status of a drug container of a drug delivery device are provided. The drug container can hold a liquid drug. A plunger can be positioned within the drug container. A drive system can advance the plunger to expel the liquid drug from the container. A monitoring system can detect a movement and/or a position of the plunger and/or any component coupled to the plunger. The detection can enable determination of an amount of liquid drug that has been expelled and/or an amount of liquid drug remaining in the drug container. Dosing rates, flow rates, and dosage completion can also be determined.

An electronic device includes a mouthpiece, a bladder, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the bladder.
