Definitions

  • the present disclosure relates to apparatus, systems and methods for fluid delivery, specifically to controlling the delivery of an injection fluid to a target site.
  • Regional anaesthesia is a procedure that provides the loss of sensation to a specific area of the body by disrupting the transmission of signals along nerves.
  • the local anaesthetic is administered through injection and the solution surrounds the nerve plexus inhibiting sodium ion conductance, stopping the transmission of noxious stimuli.
  • Intravenous injection may cause a toxic reaction and may cause the anaesthetic to spread throughout the body instead of providing a localised dose to the area of interest, with potentially life threatening consequences. Damage to nerves can be caused by direct needle trauma or by excessive injection pressures .
  • a fluid delivery system for example this may be a system for injecting medical compositions into a human or animal body, e.g via a fluid delivery lumen such as a hypodermic needle.
  • the system comprises a syringe and a valve; wherein the syringe comprises an aspiration barrel and an injection barrel; and the valve is configured to control fluid flow between the syringe and a fluid delivery lumen for aspiration and injection of a target site; wherein the valve is operable in a reverse and forward position, such that in the reverse position the valve is configured to enable fluid to flow from the fluid delivery lumen to the aspiration barrel; and in the forward position the valve is configured to enable fluid to flow from the injection barrel to the fluid delivery lumen.
  • the valve 120 further comprises a fluid delivery lumen connector 123 arranged to couple to a fluid delivery lumen such as the needle 130.
  • the fluid delivery lumen connector 123 is configured to provide fluid to and obtain fluid from a target site via a fluid delivery lumen e.g. the needle 130.
  • the valve 120 is configured to switch the system between an aspiration configuration and an injection configuration. In the aspiration configuration the valve 120 provides a flow path between the needle 130 and the aspiration barrel 104 via the valve 120 and connection tube 141. In the injection position, the valve 120 provides a flow path between the injection barrel 105 and the needle 130 via connection tube 142. Valve structure and operation is described further with reference to Figures 3A-E.
  • the syringe 200 comprises an aspiration barrel 204 and an injection barrel 205, and further comprises a first plunger 210 configured to move slidably within the aspiration barrel 204, and a second plunger 220 configured to move slidably within the injection barrel 205.
  • the syringe 200 further comprises a biasing means 209 for driving the second plunger 220 to pressurise fluid in the injection barrel 205.
  • the biasing means is a spring and is mounted on the second plunger 220.
  • a spring is shown and described above, other biasing means are envisaged, for example a tensile element for providing a tension force on the plunger may be provided.

Abstract

L'invention concerne un système de distribution de fluide comprenant une seringue et une valve, la seringue comprenant un cylindre d'aspiration et un cylindre d'injection. La valve est configurée pour commander un écoulement de fluide entre la seringue et une lumière de distribution de fluide pour l'aspiration et l'injection d'un site cible; la valve pouvant fonctionner dans une position inverse et vers l'avant, de telle sorte que, dans la position inverse, la valve est configurée pour permettre au fluide de s'écouler de la lumière de distribution de fluide au cylindre d'aspiration; et dans la position vers l'avant, la valve est configurée pour permettre au fluide de s'écouler du cylindre d'injection à la lumière de distribution de fluide.
