Abstract
The present disclosure relates to a needle extraction syringe () for extracting fluid and/or tissue comprising: a barrel () having a proximal lumen (); and a distal lumen () for collecting aspirated fluid/tissue; a plunger () having a plunger head () sealingly engaged inside the barrel (); and a plunger body () with an internal channel (); a valve () located between the plunger head () and a distal end of the syringe inside the barrel (), separating the proximal lumen () and the distal lumen () such that air can only flow from the distal lumen () to the proximal lumen () in a first valve configuration; a sealing element () located inside the barrel () proximal to the plunger head (), wherein the plunger head () and the sealing element () define a vacuum chamber () having a variable volume therebetween, wherein the vacuum chamber () and the internal channel () are fluidly disconnected in relation to each other in a first configuration of the syringe and fluidly connected in a second configuration of the syringe.
