Title
(EN) DEVICE FOR CONTAINMENT AND RELEASE OF A TRANSDERMAL DRUG FORMULATION
(FR) DISPOSITIF POUR CONTENIR ET ADMINISTRER UNE PRÉPARATION DE MÉDICAMENT TRANSDERMIQUE
Abstract
(EN)
This invention relates to a device that uses microneedles (5) to create pores in the skin (8) of a subject and delivers the drug transdermally by inserting it into the pore as a solid or semi-solid mass (7) alongside each needle (5). The device is sufficiently flexible to allow relative movement of the needle (5) and the drug mass (7) apart from one another. Preferably a chamber (4) holding the drug mass (7) comprises a relatively rigid wall (2) to ensure that the drug (7) remains aligned close to the needle (5), while an adjacent chamber (3) holding the needle (5) comprises a relatively flexible wall (1) to allow lateral movement of the needle (5) as the drug (7) is inserted alongside it.
(FR)
La présente invention concerne un dispositif qui utilise des micro-aiguilles (5) afin de créer des pores dans la peau (8) d'un sujet et administre le médicament par voie transdermique en l'introduisant dans le pore sous forme de masse (7) solide ou semi-solide à côté de chaque aiguille (5). Le dispositif est suffisamment flexible pour permettre un mouvement relatif de l'aiguille (5) et la masse (7) de médicament les séparant l'une de l'autre. De préférence, une chambre (4) contenant la masse (7) de médicament comprend une paroi (2) relativement rigide afin de garantir que le médicament (7) reste aligné près de l'aiguille (5), tandis qu'une chambre adjacente (3) contenant l'aiguille (5) comprend une paroi (1) relativement flexible pour permettre un mouvement latéral de l'aiguille (5) lorsque le médicament (7) est introduit à côté d'elle.
