Abstract
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.
