The device of the method of infusions epidural by an automatic testing of suction to search for the loss of strength and analysis of the fluid to be infused or sucks

摘要

Securing device of the infusion epidural by tests of the suction with automatic search for the loss of strength and analysis of the fluid is injected or aspiré.l' invention comprises the production of tests of the suction and the optional automatic analysis by a sensor placed on the infusion line of the qualities of the fluid is injected or sucked up during these tests of aspiration.lors tests of the suction, the push rod (1) of the apparatus of the infusion takes a traction on the syringe plunger and a holding of this traction during a period of time has been determined, to the search for a resistor (2) at the rear return. In case of disappearance of the latter, an alarm (3) is reflected and the infusion is stopped. A sensor (4) which are internal or external can be arranged on the infusion line (5) so as to detect the variations of the quality of the fluid circulating therein. In the event of a variation in quality of the fluid, an alarm (3) is reflected and the infusion is arrêtée.le device according to the invention is particularly suitable for the treatment of pain for use with an epidural pushes - electric syringe or by an apparatus for analgesia controlled by the patient and is intended to detect the disconnection of the catheter, the migration of a vascular that - latter or its migration intra - intrathecal.
