Abstract

The invention relates to a device for subcutaneous administration of a medicament to a patient, comprising a cannula housing (1) with an interior chamber, a cannula (2) connected to said cannula housing (1) and being in flow communication with the interior chamber, a flexible tubing (4) having a first end (4′) and a second end (4″), wherein the tubing (4) is, at the first end (4′), coupled to the cannula housing (1) such that the tubing (4) is in flow communication with the interior chamber, and wherein, at its other end (4″), the tubing carries a source coupling (5), whereby the tubing (4) can be coupled to a source for said medicament. The invention is characterised in that the tubing (4) is, between the first and the second end (4′, 4″), folded (9, 9′) for forming a configuration with at least two essentially parallel courses (14, 24, 34) of tubing, that the tubing (4) is secured in said configuration by means of a first holder device (10) arranged between the first and second end (4′, 4″) of the tubing; and that the tubing (4) can be displaced in relation to said first holder device (10) for varying the length of said courses (14, 24, 34) of tubing.
