Needle device comprising a plurality of needles
First Claim
1. A needle device (100, 200, 300) comprising:
- a mounting surface adapted for application to the skin of a subject, adhesive means (115, 215) arranged on the mounting surface for adhering the needle device to the skin of the subject, a plurality of needles (161, 261, 346), each needle comprising a distal pointed end adapted to penetrate the skin of the subject, 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, the needles being 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.

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.

22. A system (400) comprising sensor means (410) and drug infusion means (420), the drug infusion means comprising:
-
a first mounting surface (421) adapted for application to the skin of a subject, a plurality of hollow needles (422), each needle comprising a distal pointed end adapted to penetrate the skin of the subject, wherein each of the hollow needles has a first position in which the distal end is retracted relative to the first mounting surface, and a second position in which the distal end projects from the first mounting surface, the needles being 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, a reservoir adapted to contain a liquid drug and comprising an outlet in fluid communication with at least one hollow needle when it is in its second position, expelling means for expelling a drug out of the reservoir and through the skin of the subject via the hollow needle, the sensor means comprising;
a second mounting surface (411) for application to the skin of a subject, a plurality of needle-formed sensors (412) having a distal end adapted to be inserted subcutaneously through the skin of the subject, wherein each of the needle-formed sensors has a first position in which the distal end is retracted relative to the second mounting surface, and a second position in which the distal end projects from the second mounting surface, the needle-formed sensors being 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, each of the needle-formed sensors being adapted for providing a sensor signal indicative of a glucose level in blood, control means adapted to receive signals from the sensors and generate command signals in response thereto in order to keep the blood glucose level of the patient within a desired range, wherein operation of the delivery means is affected by the command signals. - View Dependent Claims (23)
