FIELD: medicine. ^ SUBSTANCE: invention refers to medical equipment, namely a device for introduction, e.g. of a cannula and an infusion kit for intermittent or continuous introduction of a drug preparation, such as, e.g. insulin. The device for subcutaneous introduction of the cannula comprises a first portion for introduction and a second portion for introduction, a portion for cannula retention provided with the cannula, and also an injection needle. The second portion for introduction comprises a portion for needle retention provided with the injection needle. The injection needle is detachably coupled with the cannula of the portion for cannula retention. The portion for needle retention either comprises a portion of the second portion for introduction, or is fixed relatively to the second portion for introduction. The first portion for introduction covers the injection needle in its idle position, while in an actuated position the injection needle projects from the first portion for introduction. At least the portion of the second portion for introduction and the first portion for introduction can move relatively to each other between at least one actuated position and at least one idle position. The second portion for introduction projects from a distal end of the first portion for introduction when the device is actuated. An elastic member promotes transfer of the second portion for the introduction coupled with the injection needle, from the front, i.e. actuated position, into the retracted, i.e. idle position. ^ EFFECT: invention reduces a risk of user's injury caused by an accidental needle prick. ^ 17 cl, 17 dwg |
