Abstract:
1. A needle device comprising: a mounting surface adapted for application to the skin of a subject, adhesive means arranged on the mounting surface for adhering the needle device to the skin of the subject, a plurality of needles, each needle comprising a distal pointed end adapted to penetrate the skin of the subject, and a common fluid conduit member having a fluid inlet adapted to receive fluid from a fluid source, wherein each needle has a first position in which the distal end is retracted relative to the mounting surface, and a second position in which the distal end projects from the mounting surface, wherein a plurality of the needles are hollow having a distal and a proximal opening, whereby the proximal opening of each of the hollow needles can be arranged in fluid communication with the same fluid inlet via the common fluid conduit member when the respective needle is in its second position, the proximal opening being in fluid communication with the common fluid conduit member and thereby the fluid inlet when the needle is in its second position, wherein the needles being are arranged such that at least one needle can be moved from its first to its second position or from its second to its first position with at least one other needle not performing the same movement, and wherein the fluid inlet is stationary relative to the mounting surface.
