A device (10) for rapid vascular drug delivery, particularly through the adult sternum or the pediatric tibia, incorporates a cylindrical syringe body (12), fitted with a needle (14). The syringe body is held in a cylindrical main housing (16) having a front barrel (18) with an orifice (20) through which the needle (14) may be extended. A cylindrical actuation handle (22) fits over end (24) of the main housing (16) for sliding movement along the main housing. A syringe plunger (26) contacts drive plunger (28) and extends into the syringe body (12) from end (30) to confine liquid medication (32) in the syringe body (12). A main spring (34) extends between the drive plunger (28) and the actuation handle (22) to bias the actuation handle (22) in its extended position. A needle return spring (38) extends between the front barrel (18) and the syringe body (12) to bias the needle to its retracted position. The drive plunger (28) has an annular peripheral socket (42) for one or more lock balls (44) which engage one or more openings (45) on the main housing (16) to lock the drive plunger in position with respect to the syringe body (12). A mating annular lock ball trip pocket (46) is positioned on inside surface (48) of the actuation handle to allow the device (10) to be fired when the lock ball(s) in socket (42) reach the pocket (46).

System and method for rapid vascular drug delivery

A laptop computer (10) with a tiltable and swivelable display (12) is connected to case (29) by a pivot mechanism (20) and a swivel mechanism (33). In the pivot mechanism (20), a first pivot (22) connects display (12) to a pivot plate (50), and the second pivot (24) connects the pivot plate (50) to base (32) of the display (12). The first pivot (22) consists of a pair of pivot pins (52) on each end of the pivot plate (50). The second pivot (24) consists of split pivot pins (54) at each end of the pivot plate (50). The pivot pins (54) and inboard shafts (58) are fastened together and inboard shafts (58) rotate within outboard shafts (56). The outboard shafts (56) and the inboard shafts (58) are surrounded by clutch springs (60), which are connected so that the clutches are in their free rotating direction, i.e., does not resist motion between them when the display is being opened, and which resist motion between the inboard shafts (58) and outboard shafts (56) when the display is being lowered, to produce a greater friction than produced by the first pivot (22). The swivel mechanism (33) consists of a first swivel member (70) fixedly attached to case (29) and a second swivel member (72) which is fixedly attached to display base (32) and nests inside the first swivel member (70). The second swivel member (72) rotates inside the first swivel member (70).
