Embodiment Construction

[0040] figure 1 A- figure 1 E shows an embodiment of a base part system comprising a plate 1 with two separate openings 12a, 12b through which a subcutaneous unit in the form of a cannula part 22a, 22b can be mounted. The plate 1 is usually made of a hard and relatively rigid material, such as metal or a hard plastic, such as polyethylene (PE), polypropylene (PP), polystyrene (PS) or similar. Usually, the definition "relatively rigid" is used, because the hardness of a material depends not only on the material chosen, but also on the dimensions of the material, such as the thickness and width of the plate, that is, by increasing the thickness of the plate, the same material can be made relatively more rigid. rigidity.

[0041] Usually, in this technical field, if a material's Young's modulus > 0.6GPa (close to 87.000lbf / in 2 (psi)), the material is considered rigid. According to the claim, the board is mainly made of hard material, which means that a small part of the boar...

Abstract

The invention concerns a base part system for a medication delivery device. The base part system to be combined with a detachable reservoir / delivery part according to the application comprises a plate (1) provided with a mounting surface (1a) and openings (12a, 12b) through which two or more subcutaneous units in the form of at least two subcutaneously positioned cannulas (22a, 22b) or at least one subcutaneously positioned cannula and e.g. a subcutaneously positioned part of a sensor extend during use. During use at least one subcutaneous unit in form of a cannula part is attached to the plate (1) with fastening means (25). The subcutaneous unit comprises a body part (7) placed above the patient's skin which is provided with handling means (26) allowing a user to detach the subcutaneous unit from the plate (1) and to remove the used subcutaneous unit from the patient.

Description

technical field [0001] The present invention relates to a base component system for a drug delivery device. The system includes a base member plate and two or more units positioned subcutaneously during use, at least two of the subcutaneously positioned units being cannula members. The two subcutaneously positioned units may be positioned subcutaneously during overlapping time intervals, or within non-overlapping time intervals. In use, the base part plate is secured to the patient's skin and connected to a separate cannula part positioned at least partially under the skin. At least one second cannula and eg several other cannulae are also connected to the base part plate. The handling device is connected to the cannula part, whereby the cannula part can be easily retracted after a period of use. Background technique [0002] Document US2004 / 0162521 discloses a needle device comprising a housing, a base part having a mounting surface adapted for application to the skin of...
