Needle device comprising a plurality of needles
First Claim
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, anda 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, andwherein the fluid inlet is stationary relative to the mounting surface.

Abstract
A needle device comprises a housing, a base portion having a mounting surface adapted for application to the skin of a patient, and a plurality of needles. Each needle comprises a distal pointed end adapted to penetrate the skin of the subject, and 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. The needles are arranged such that at least one needle can be moved from its first to its second position, or vice versa, with at least one other needle not performing the same movement. In this way a plurality of needles can be introduced transcutaneously at a selected site within the body of a subject. The device may comprise a common fluid conduit with at least two of the needles having a proximal opening to be arranged in fluid communication with the common fluid conduit.
