An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.

A reagent pack includes a first reservoir having a continuous rigid wall defining a constant inner space that opens to the ambient environment. An air-tight second reservoir has a flexible wall that defines a variable inner space with one or more second openings. The second reservoir is arranged within the first reservoir and stores fluid reagent. A closure element completely fills the first opening of the first reservoir and includes a first fluid passage fluidly connecting the inner space of the first reservoir, as the waste reservoir, to receive waste liquid. Second fluid passages fluidly connect the second openings of said second reservoirs with respective reagent inlets to supply fluid reagent to the sample analyzer. The inner space of the first reservoir further includes an air passage to allow gaseous communication with the ambient environment to maintain a controlled pressure within said inner space while receiving waste liquid.

A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus 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. The mouthpiece, the bladder, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the bladder. A liquid-filled cartridge also is disclosed for use with an electronic device for delivery of a substance into a body through respiration includes a liquid container; and a liquid contained within the container for aerosolizing and inhaling by a person using the electronic device.
