Abstract (en)
[origin: GB2575127A] A fluid delivery system 100 comprising a syringe 110 and a valve 120. Syringe 110 comprises an aspiration barrel 104 and an injection barrel 105. Valve 120 controls fluid flow between the syringe 110 and a fluid delivery lumen 130 for aspiration and injection of a target site. Valve 120 is operable in a reverse and forward position, such that: in the reverse position the valve 120 enables fluid to flow from the fluid delivery lumen 130 to the aspiration barrel 104; and in the forward position the valve 120 enables fluid to flow from the injection barrel 105 to the fluid delivery lumen 130. Valve 120 may be operable in a neutral position, where the valve 120 prevents fluid flow between the syringe 110 and the fluid delivery lumen 130. Syringe 110 may comprise a biasing means 109, possibly a spring, to pressurise fluid in the injection barrel 105, where biasing means 109 may provide an injection fluid pressure that does not exceed one of 30 psi (206.8kpa), 20 psi (137.9kpa), 15 psi (103.4kpa) or 10 psi (68.9kpa). Described as being for use by anaesthetists seeking a suitable target to inject a local anaesthetic into a subject.
