Abstract: A sequential stopper having structural features for facilitating substantially complete delivery of fluid held within a syringe barrel. The sequential stopper features a stopper body having a cylindrical side wall, proximal and distal ends, and one or more circumferentially-disposed sealing elements thereabout. One of the circumferentially-disposed sealing elements may be located adjacent the proximal end of the stopper body. An elongate hollow chamber is disposed within the stopper body parallel to the longitudinal axis of the stopper body. A pair of longitudinal sealing elements are disposed on the cylindrical side wall of the stopper body and are separated on the sidewall by a distance greater than a maximum width displayed by the elongate hollow chamber disposed within the stopper body. A recessed surface is disposed between the longitudinal sealing elements adjacent the proximal end of the stopper body.

Abstract: An assembly for automatically injecting a fluid into the body is provided. The assembly includes a drive assembly, which can be reused many times, and a disposable assembly including a sleeve which contains a syringe. The drive assembly includes a housing having an open end to which a collar is mounted. The collar includes a radially inwardly extending pawl. The sleeve includes a generally cylindrical body having a radially outwardly extending rib. The rib defines a notch which is engageable with the pawl when the disposable assembly is inserted within the drive assembly housing. Engagement of the pawl within the notch prevents the disposable assembly from being ejected from the drive assembly housing should the actuating button of the drive assembly be pushed prematurely. Ejection of the disposable assembly requires its rotation with respect to the drive assembly housing to first disengage the pawl from the notch.

Abstract: The bottle (10) includes a narrowed neck (12) closed by a sealing body (29) provided with a radial channel (31) mounted on a capsule (32) sitting on said neck (12). The capsule (32) includes a connecting piece (34) protected by a cap (39). The bottle (10) is of the type with two compartments separated by an intermediate mobile stopper (18). The connecting piece (34) is conical and enables a Luer-lock type connection to be made with another bottle or with an apparatus for using the medicamental substance obtained after mixing the substances contained in the two compartments.

Abstract: A protective safety cap assembly for the passageway of a medical device is provided. The safety cap assembly includes a cap that is guided for sliding and pivotable movement between a closed position where the proximal end of the medical device is easily accessed and a closed position where the proximal end of the medical device is sealed. The medical devices which can be protected by the cap assembly include hypodermic syringes, stopcock assemblies associated with I.V. lines and catheters, or the like. A medical worker holding the medical device in one hand can easily and repeatedly move the cap between the opened and closed position with a thumb or forefinger of the hand holding the medical device.

Abstract: A safety needle assembly for providing secure connection of a needle cannula to a straight-site or Y-site of an intravenous fitting. The assembly includes a base portion and a protective shield disposed about the needle cannula to at least partially envelop the needle cannula within the shield. A latch is pivoted to the shield so as to releasably lock the intravenous fitting within the shield. The latch includes a pivot arm having at least one shield engaging finger member disposed to biasingly engage at least a portion of the shield, and at least one member disposed through a passageway formed in the shield to trap the intravenous fitting within the shield.
