Powder dispensing and sensing apparatus and methods are provided. The powder dispensing and sensing apparatus includes a tray support structure to receive a cartridge tray holding cartridges, a powder dispenser assembly including powder dispenser modules to dispense powder into respective cartridges of a batch of cartridges in the cartridge tray, a powder transport system to deliver powder to the powder dispenser modules, a sensor module including sensor cells to sense respective fill states, such as the weights, of each of the cartridges in the batch of cartridges, and a control system to control the powder dispenser modules in response to the respective sensed fill states of each of the cartridges of the batch of cartridges.

Powder dispensing and sensing apparatus and methods for simultaneous filling of cartridges

Powder dispensing and sensing apparatus and methods

An inhaler is instantly activated upon its removal from a cover or cover unit, and by rotating a cartridge component of the inhaler with respect to a mouthpiece portion, so as to create a flow pathway for ambient air and particles. The cartridge component includes a chamber, whose contents typically include dry powders or the like. Upon creation of the flow pathway, the contents of the chamber are instantly accessible for immediate inhalation by a user through the mouthpiece portion.

Inhalation apparatus

A powder dispenser module () includes a housing () that defines a conduit connecting a powder inlet and a powder outlet, a feed wand () to move powder through the conduit from the powder inlet to the powder outlet, the feed wand () including a lower feed element () coupled to a first drive shaft and an upper feed element () coupled to a second drive shaft, a first actuator coupled to the first drive shaft to rotate the lower feed element (), and a second actuator coupled to the second drive shaft to rotate the upper feed element (). In other embodiments, the feed wand () includes a shaft having a fluidizing element and an actuator produces oscillatory movement of the feed wand during dispensing of powder. Dispenser module arrays include one or a few rows of dispenser modules.

Powder dispenser modules and powder dispenser assemblies

Described is a dry powder inhaler comprising an intake section; a mixing section, and a mouthpiece.

Unit dose capsules and dry powder inhaler

A dry powder inhaler having improved aerodynamic properties for diluting, dispersing, and metering drug particles for increasing the efficiency of pulmonary drug delivery to a patient is described. The inhaler comprises, in general, a housing having an air intake, an air flow-control/check-valve, a mixing section and a mouthpiece. A cartridge loaded with a single dose of medicament can be installed in the mixing section.
