SYSTEM AND METHOD FOR RAPID VASCULAR DRUG DELIVERY.

摘要

the device (10) for rapid vascular drug administration in particular. as an adult, or a child of the tibia, which comprises a cylindrical syringe body (12) with a needle (14). the body is maintained in a syringe housing (16) having a central cylindrical bore (18) has a first opening (20) through which the needle (14) may protrude.a cylindrical brake handle (22) is applied to the end (24) of the housing (16) leading to enable sliding movement along the housing.the plunger of a syringe (26) is in contact with a piston rod (28) and extends into the syringe body (12) from the end (30) of the latter in order to push the medicine liquid (32) in the body of the syringe (12).a spring extends between the core (34) of the piston rod (28) and the handle (22) of the brake actuator so as to push the handle (22) in the extended position. a spring for retracting the needle (38) that extends between the front barrel body (18) and the needle (12) in order to push the needle in the retracted position.the piston rod (28) comprises a peripheral casing (42) for receiving an annular blocking one or more bearings (44) which engage with one or more openings (45) located within the main housing (16) so as to lock the rod in position relative to the c orps syringe (12).an annular pocket (46) trigger for receiving logs matched block is located on the inner surface (48) of the handle to allow the triggering of the actuation device (10) where the ball (s) block in the casing (42) into the pocket (46).
