Breath actuated nebulizer

A breath actuated nebulizer for administration of an inhaled medication to a patient is provided with a generally cylindrical body in a horizontal orientation to the patient. Within the body is a Venturi configured to nebulizer a liquid medication in a reservoir. Within the body is a shaft integrated with a baffle and diaphragm that slides horizontally in response to the breathing of a patient. During inhalation by the patient, the diaphragm flexes shifting the baffle over the Venturi, allowing nebulization to occur. When the patient exhales, the diaphragm flexes to a default position in which the baffle is distal to the Venturi, thereby stopping the nebulization. The diaphragm is biased to rest in this default position until the patient inhales again.

DRY POWDER INHALER AND SYSTEM FOR DRUG DELIVERY

A breath-powered, dry powder inhaler, a cartridge, and a pulmonary drug delivery system are provided.

HAND-HELD DEVICE FOR DISPENSING SPRAYABLE SUBSTANCES IN A PORTIONED MANNER
20210316092 · 2021-10-14 ·

A hand-held device for metered dispensing of sprayable substances, in particular inhaler medicaments, includes a housing and a cartridge which can be displaced into a dispensing position by a pressure application relative to the housing, wherein the housing has a mouthpiece, wherein the cartridge can be displaced initially into a ready-to-dispense position and a dispensing spray process can be triggered by sucking in, wherein the displacement of the cartridge can be executed by tensioning a spring supported on the housing and acting on the cartridge. The spring is displaced into the position to perform a spraying process, but is hindered by a counterforce that can be deactivated by application of a negative pressure through the mouthpiece of the hand-held device A valve flap is moved by the negative pressure and cancels a mechanical block of the movement of the cartridge.

TESTING METHOD FOR A DRY POWDER INHALER

The invention provides a method of testing an inhaler based on performing an optical analysis of a dry powder medicament plume discharged from the inhaler upon actuation. More particularly, embodiments of the invention comprise illuminating the dry powder plume with a source of electromagnetic radiation and capturing one or more images of a pattern of radiation reflected or diffracted by the illuminated plume. The images are subsequently processed to determine and/or analyse one or more geometric and/or dynamic characteristics of the plume.
