  • Publication number: 20190117895
    Abstract: A valve for permitting mixing of at least two components within a barrel is provided including a stopper configured for slidable liquid-tight engagement with an inner surface of the barrel. The stopper is moveable between a first position and a second position and includes a proximal end, a distal end, and a channel extending therebetween. The valve further includes a stationary body comprising a base and a stem, the stem being disposed within the channel of the stopper when the stopper is in the second position. When the stopper is in the first position, there is a liquid-tight seal in the channel, such that fluid flow through the channel is prevented. Movement of the stopper to the second position terminates the liquid-tight seal, thereby establishing fluid communication through the channel. A drug containing device and assembly for delivering a reconstituted drug are also provided herein.

  • Patent number: 10195344
    Abstract: A valve (10) for permitting mixing of at least two components within a barrel (12) is provided including a stopper (20) configured for slidable liquid-tight engagement with an inner surface (13) of the barrel. The stopper is moveable between a first position and a second position and includes a proximal end (22), a distal end (24), and a channel (26) extending therebetween. The valve further includes a stationary body (30) comprising a base (32) and a stem (34), the stem being disposed within the channel of the stopper when the stopper is in the second position. When the stopper is in the first position, there is a liquid-tight seal in the channel, such that fluid flow through the channel is prevented. Movement of the stopper to the second position terminates the liquid-tight seal, thereby establishing fluid communication through the channel. A drug containing device and assembly for delivering a reconstituted drug are also provided herein.

  • Publication number: 20090043263
    Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The barrel may include a barrel adapter at one end to define a luer hub socket and the outer walls of slots in the barrel. The plunger includes an outer plunger element and an inner plunger element telescoping together with a bungee resisting extension of the assembly. The inner and outer plunger elements may be locked in the extended position with the bungee in tension. A seal stop is located at the seal end of the plunger to define an annular pinch therewith to hold an annular seal in radial extension sealing against the internal sidewall of the barrel. A luer hub is fixed at the needle end of the barrel, A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation.

  • Patent number: 7393343
    Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The plunger includes an outer plunger element and an inner plunger element telescoping together. A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation. The rotation actuates latches and locking fingers on the luer hub to engage a probe axially and rotationally on the seal end of the plunger and disengage the slots in the barrel, respectively. The rotation disengages the seal stop to release the annular seal and finally releases the engagement between the outer plunger element and inner plunger element. The foregoing provides for the retraction of the luer hub and associated needle into the barrel.

  • Patent number: 5897840
    Abstract: A urine specimen container is disclosed which includes multiple urine holding chambers and further includes a cap to be secured to the container that enables extraction of a portion of the urine specimen from one chamber within the container without contaminating the urine specimen contained in an adjacent chamber of the same container.
