Abstract
The device for administering medicinal preparations comprises an isolated capsule subdivided into a chamber for a first medicinal preparation and a chamber for a second medicinal preparation. Coaxially inside said isolated capsule concentrically therewith is the piston which bounds said chamber for the first medicinal preparation. Made fast on said piston is the injection needle having the hole located at the base of said piston. Provision is made in the device for a mechanical actuator of said piston, which is a spring-opposed pushrod located inside the housing which also accommodates the retaining member for said spring-opposed pushrod. Said chamber for the second medicinal preparation is arranged concentrically with said chamber for the first medicinal preparation so as to embrace the latter. Said isolated capsule is mounted traversably inside said housing, while communication between both of said chambers is established upon a positive extension of said isolated capsule from said housing outwards.
