Abstract
A dispensing device, a storage device and a method for dispensing a medical formulation are proposed. Multiple doses of the formulation are stored in a carrier having multiple inserts, each insert containing a single dose. Preferably, each insert has at least one duct or nozzle for dispensing the respective dose. Each insert is located in a separate and sealed cavity in the carrier. The cavities can be individually opened for dispensing the respective dose from the respective insert.
Claims26
Dispensing device for dispensing a medical formulation as a spray of fine particles, the dispensing device comprising multiple separate and pre-metered doses of the formulation, wherein the dispensing device comprises a carrier with multiple inserts, at least some of the inserts containing a single dose of the formulation and means for individually dispensing the formulation from the respective insert;
- wherein each insert comprises a gas inlet at one end of each insert, a gas outlet at an opposite end of each insert, and a storage chamber between the gas inlet and gas outlet that is substantially circular in cross section viewed in a direction transverse of a direction from the gas inlet toward the gas outlet, the gas inlet being tangentially connected to the storage chamber to generate swirls of the formulation.
Method for dispensing a preferably medical formulation as a spray including fine particles from a storage device comprising multiple separate and pre-metered doses of the formulation, comprising the steps of:
- storing the doses in multiple inserts in a carrier with each insert containing one dose of the formulation and being located in a separate sealed cavity of the carrier,
- individually opening the cavities for dispensing the respective dose from the respective insert by means of a piercing element, the piercing element piercing a sealing covering the respective cavity,
- following opening of the respective cavity, using the piercing element to pierce the respective insert and
- after the respective insert is pierced by the piercing element, supplying pressurized gas through the piercing element into the pierced insert to dispense the dose of formulation contained in the respective insert pierced.
