CA 2703337

Some embodiments of a spray device can be configured to maintain a viscous fluid in isolation from a propellant fluid until after the viscous fluid exits from a nozzle of the spray device. For example, the viscous fluid may comprise an adhesive such a surgical adhesive. When the spray device is actuated, the surgical adhesive can exit the nozzle whereat the propellant fluid acts upon the surgical adhesive to break it into droplets for application on a targeted site.

L'invention concerne un dispositif de pulvérisation dont certains modes de réalisation peuvent être configurés de façon à maintenir un fluide visqueux isolé d'un fluide propulseur jusqu'à ce que le fluide visqueux soit sorti d'une buse du dispositif de pulvérisation. Par exemple, le fluide visqueux peut comprendre un adhésif comme un adhésif chirurgical. Lorsque le dispositif de pulvérisation est actionné, l'adhésif chirurgical peut sortir de la buse au niveau de laquelle le fluide propulseur agit sur l'adhésif chirurgical pour le fractionner en gouttelettes en vue de son application sur un site cible.
