Syringe for the automatic identification of the epidural space

摘要

The syringe for the automatic identification of the epidural space is composed of a syringe (6) of low friction and displacement of the plunger (11) and two accessories coupled to the same, a tap (15) with the rotor (2) for three derivations of valvular flow (1), (5), (7), and a laminar band) Rcular latex (4) distended by filling with local anaesthetic (9),Supported on the plunger of the syringe (11) and the tap (15), in the derivation (1) buffer (3) is characterised by the constant pressure exerted by the band laminar Circular of latex on the syringe plunger (11) during the progression of the syringe needle assembly (6) - (8) with fins (14) that expelled, aut Omaticamente,The content of anesthesia (9) of the syringe (6) at the moment when the tip of the needle (8) invades the space pendurai, differentiating itself from the current technique by the inaccuracy of digital pressure to the anesthesiologist is on the plunger of the seringa.u00e0 measure which the puncture moves (Figure 10) in the direction of the The space pendurai.
