A delivery device for and a method of delivering gases to the nasal airway, in particular therapeutic gases and gases in combination with active substances, either as powders or liquids, for enhanced uptake of the active substances.

A dispenser device for fluid or powder, including an air expeller (20) and a reservoir (30). The reservoir (30) has an air inlet (31) connected to the air expeller (20) and a composition outlet (32) connected to a dispenser opening (10), and is removably mounted on the air expeller. After actuation, the empty reservoir can be removed from the air expeller and replaced with a new reservoir. The air inlet (31) is closed by a first closure element (40) and the composition outlet (32) is closed by a second closure element (50). A mechanical opening system (61, 62) co-operates with the first and second closure elements to expel each closure element from the closed position. The mechanical opening system has a first rod (61) secured to the air expeller (20), and a second rod (62) secured to the dispenser head (1), co-operating with a closure element during actuation.

A dry pharmaceutical composition is provided that is suitable for respiratory tract delivery of levodopa and DDI for treatment of Parkinson's disease or Parkinson syndrome. The dry pharmaceutical composition comprises levodopa, a dopa decarboxylase inhibitor (DDI) and at least one excipient. A unit dosage form of the dry pharmaceutical composition and a method of treating a patient with Parkinson's disease or Parkinson syndrome by administering the dry pharmaceutical composition are also provided.

A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives, powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.

Dispenser, comprising a reservoir (10) containing fluid product, a head (20) provided with an opening (21), a piston (50) for dispensing at least one portion of the fluid product through the opening (21), the reservoir (10) being, before the dispenser is actuated, closed in sealed manner by the piston (50), the device comprising a hollow insert (60) inserted and fixed in the head (20), the insert (60) supporting a cannula (40) for piercing the piston (50) and thus connecting the container (10) to the opening (21) during actuation, wherein:

said dispenser head (20) includes a proximal end portion (220) of reduced diameter the axial length of which is greater than 5 mm, advantageously greater than 6 mm, the maximum outside diameter of which is less than 8 mm, advantageously less than 7 mm, and the wall thickness of which is less than 1.1 mm, advantageously between 0.7 and 1.0 mm;

said dispenser head (20) comprises an inner side wall comprising a first proximal cylindrical section (25) and a second distal cylindrical section (26) of diameter greater than that of said first proximal cylindrical section (25), said insert (60) comprising on its outer wall a first proximal radial projection (65) extending over the entire periphery, said first proximal radial projection (65) cooperating in a tight and sealed manner with said first proximal cylindrical section (25), in order to ensure the sealed fixing of said insert (60) in said dispenser head (20).

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

A system includes a charger and a cracker. An antiviral may be delivered through the charger. The cracker may include a first section and a second section to control the flow of the antiviral from the charger. The first section may receive the charger. The first section and the second section may be coupled together by using screw threads on the first and second sections. The cracker is configured to regulate the flow of antiviral into the user. The antiviral within the charger may include oxygen (O2) and nitrous oxide (N2O). Specifically, the antiviral may a mixture including 75% N2O and 25% O2 that inactivates the DNA and/or RNA of viruses, viroids, and germs.

A device for delivering a predetermined amount of at least one substance to a body orifice of a subject includes a) a container for containing said at least one substance; b) a delivery end for placement in proximity to the orifice, the delivery end being in fluid communication with the container; c) a valve mechanically connectable to said container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end; and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice; d) a trigger mechanism adapted to reconfigure said valve from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, and vice versa; and e) a fluid tight chamber.
