Abstract
There is provided a medicament dispenser comprising a body (44), a medicament container and transport means to transport a metered amount of medicament from a rest position to a delivery position wherein the transport means comprises a transport coupling (72). The coupling (72) is reversibly deformable in response to the application of non-mechanical energy thereto. The non-mechanical energy may comprise heat energy, electrical current energy, electrical field energy or magnetic field energy.
Claims113
A medicament dispenser comprising a body, a medicament container and transport means to transport a metered amount of medicament from a rest position to a delivery position, wherein the transport means comprises a transport coupling which is reversibly deformable in response to the application of non-mechanical energy thereto.
A medicament dispenser according to any one of the preceding claims wherein the meter comprises a weight and/or volume and/or a time and/or a surface-area regulated mechanism.
A medicament dispenser according to any one of the preceding claims wherein the meter comprises a valve (for example, a linear or rotary valve) and/or a piston and/or a load cell and/or a plunger.
A medicament dispenser according to any one of the preceding claims wherein the meter comprises at least one metering chamber.
A medicament dispenser according to any one of the preceding claims wherein the transport means comprises a perforated strip and claw advancement mechanism and/or a ratchet wheel and a driving pawl advancement mechanism.
A medicament dispenser according to any one of the preceding claims further comprising release means.
A medicament dispenser according to any one of the preceding claims additionally comprising climate control means.
A medicament dispenser according to any one of the preceding claims wherein the medicament is selected from the group consisting of albuterol, salmeterol, fluticasone propionate, beclomethasone dipropionate, salts or solvates thereof and any mixtures thereof.
A medicament dispenser according to any one of the preceding claims wherein the dry powder medicament includes a pharmaceutical excipient in dry powder form.
A medicament dispenser according to any one of the preceding claims wherein the density of the dry powder medicament particles is reduced relative to standard dry powder medicament.
A medicament dispenser according to any one of the preceding claims wherein the dry powder medicament particles are aerodynamically shaped to improve medicament delivery to the patient.
A medicament dispenser according to any one of the preceding claims wherein the medicament is pre-metered prior to actuation of the dispenser by a patient.
A medicament dispenser according to any one of the preceding claims wherein the medicament container comprises medicament in solution or suspension form.
A medicament dispenser according to any one of the preceding claims additionally comprising a safety mechanism to prevent unintended multiple actuations of the transport means.
A medicament dispenser according to any of the preceding claims comprising a manual override enabling manual actuation of the transport means.
An actuator for use in a medicament dispenser according to any one of the preceding claims.
An actuator for a medicament container comprising a housing, within said housing, a container seat for receipt of the medicament container;
- on the housing or connecting therewith, transport means to transport a metered amount of medicament from a rest position to a delivery position, wherein the transport means comprises a transport coupling which is reversibly deformable in response to the application of non-mechanical energy thereto.
