A device and a method for dispensing at least one substance to a patient is presented where the device has a movable first container containing a first substance having a first piston with a first piston rod, a movable second container containing a second substance having a second piston with a second piston rod, an injection device, and a conduit device for guiding the contents of the second container to the first container and the contents of the first container to the injection device, wherein the first and the second piston are each movable via at least one pre-tensioned spring element. A free end of the first piston rod and a free end of the second piston rod are releasably held by a common holding component, and the common holding component is designed in such a way that a movement of the common holding component results in a successive release of the first piston rod and the second piston rod.

Device and method for dispensing at least one substance

A device () for dispensing a substance to a patient comprising a cylindrical first container () containing the substance and a second container () containing a liquid. The device further comprises an injection device () and transfer mechanism () for transferring the liquid from the second container () to the first container () and from the first container () to the injection device (). The first container () has a connection element () and a plunger () that can be moved between the first () and second ends (). By moving the plunger () towards the first end (), liquid contained therein can be dispensed via the injection device (). The injection device () comprises a piercing cannula () and an indwelling cannula (). In an initial position, a distal end region of the piercing cannula () extends coaxially in the interior of the indwelling cannula ().

Device for dispensing a substance

An injection device for subcutaneous delivery of fluid which comprises a puncture cannula and an indwelling cannula. In a starting position, a distal end region of the puncture cannula runs coaxially inside the indwelling cannula. The device comprises displaceably mounted first and second runners. The first runner is connected to the puncture cannula and the second runner to the indwelling cannula. A control element is movable over a predefined control area. The control element is configured such that, in a first part of the control area, the control element effects an equidirectional displacement of the first and the second runners, and hence fitting of the indwelling cannula and, in a second part of the control area, effects blocking of the second runner, and hence holding of the indwelling cannula in a dwell position, and return of the first runner and withdrawal of the puncture cannula into an end position.

Dosing apparatus and injection device

A dispensing device () for dispensing a fluid, preferably an injection syringe. The device comprises a main body () which has a longitudinal axis (A) and has a receiving space () for receiving the fluid, and a connection channel () communicates with the receiving space. The connection channel opens on a valve face () of the main body. The device comprises a movable flow control element () arranged on the main body. The flow control element has one or more flow channels () which open on a valve face () of the flow control element. The connection channel of the main body and the flow channels of the flow control element are fluidically connected to each other by relative movement of main body and flow control element. A sealing element () is arranged between the valve face of the main body and the valve face of the flow control element.
