NEEDLE SYSTEM FOR INJECTION AND ASPIRATION
A needle system (10) comprises a needle arrangement and an actuator device (30). The needle arrangement comprises needle (21) and a rod (24). The needle has a proximal end (211) and a distal end (212) and a needle opening (203) at the distal end of the needle. The rod has a proximal end (221) and a...

| description | A needle system (10) comprises a needle arrangement and an actuator device (30). The needle arrangement comprises needle (21) and a rod (24). The needle has a proximal end (211) and a distal end (212) and a needle opening (203) at the distal end of the needle. The rod has a proximal end (221) and a distal end (222) and a length that is greater than the length of the needle. The rod comprises an elongated rod shaft portion (26) configured to fit inside the needle and a rod tip portion (23) located at the distal end of the rod. The actuator device comprises an actuator body (39) comprising a cavity (33) and a first opening (61) configured to interface with a fluid transportation device(70) to allow fluid into and/or out of the cavity and thereby allowing fluid to be injected and/or aspirated through the needle. The needle system has a closed state and an open state. The rod tip portion seals, or blocks, the needle opening in the closed state, and the rod tip portion is shifted forward relative to the needle and unseals, or unblocks, the needle opening in the open state. The proximal end of the needle is connected to the actuator body and the proximal end of the needle is open to the cavity. The rod is configured to interact with the actuator device such that at a change of volume of the cavity, a force is exerted on the rod in a distal direction, setting the needle arrangement in the open state. |
