US 8137307 B2Abstract
A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.
This patent claims priority under 35 U.S.C. �119 to U.S. Provisional Application No. 60/735,481, which was filed Nov. 9, 2005; and claims priority to U.S. Provisional Application No. 60/763,647, which was filed Jan. 30, 2006.
Embodiments of the invention pertain to syringe devices, syringe piston configurations, medication agent preparation systems and methods of preparing a medication agent.
In one aspect the invention encompasses a syringe device. The device includes a syringe barrel and piston having a first end insertable within the syringe barrel. A second end of the piston opposes the first end and the piston has an overall length defined between the first and second ends. A vial port is disposed within the piston and is configured to receive a vial in lengthwise orientation along a portion of the overall length of the piston. A fluid passageway extends through the piston from the vial port through the first end of the piston.
For the syringe assembly shown in FIGS. 1 and 2, the device is preferably initially provided in a configuration in which the vial is sealed and disposed in a non-contact position relative to piercing structure 400. In preparation for use the vial can be repositioned to contact piercing device 400 and slid within the port allowing device 400 to puncture and cross the septum. Valve 300 can then be repositioned to an ‘on’ position establishing fluid communication between the vial and the syringe chamber. Sliding of the piston relative to the syringe can be utilized to combine syringe contents with vial contents. The two components can be mixed by repeated sliding of the piston or by agitation of the device. The mixed components can then be drawn into the syringe and the valve closed in preparation for administration of the prepared agent.
Joining of the second part 604 of the housing to the first part of the housing can comprise, for example, inserting a portion of part 604 into the first part, inserting a portion of part 602 within part 604, threading of one of the two parts into the other of the two parts, and/or use of other appropriate fittings or joining techniques. In particular embodiments, part 604 can preferably be configured to be stabilized in a first position and can be further extended within the second part to a second position upon application of force (sliding, twisting or other force based upon the design of the particular fitting configuration utilized). Such configuration can allow an enclosed vial to be moved from a first “non-contact” position relative to a piercing device (see FIG. 4B) into a second “access” position where the piercing device is able to pierce a vial septum or other vial cover and thereby provide access to vial contents.
The mixing/administration system 10 depicted in FIGS. 4A-4B can initially be provided in a “non-contact” position where piercing structure 400 does not puncture the cap or septum of vial 500. In a particular configuration, positioning of container parts 602 and 604 with respect to one another can be stabilized utilizing a plastic shrink-wrap at least at the junction of the two housing parts. The shrink-wrap can provide a sterile retainer and prevent inadvertent or unintentional engagement of the piercing device with the vial septum. Positioning can also or alternatively utilize a tack weld or molded attachment stabilization where a breakable attachment is provided that can be broken by application of force (twisting, sliding or other force depending upon the particular containment configuration and positioning of the breakable attachment(s)). The two-part container portion of the described syringe device configuration can be formed utilizing materials such as plastic materials, preferably hard plastic materials. Spot welding or tacking can be achieved utilizing, for example, RF welding, microwave welding, heat welding or other appropriate plastic welding.
The over-molded seal 208 can be molded to have a diameter ‘d1’ which can vary depending upon the diameter of the syringe body (not shown) that will be utilized. The tip along with the over-molded seal can be joined with a piston of an appropriate diameter (e.g. d2 or d3) for use with the particular syringe barrel. Accordingly, a single tip configuration can be utilized for a wide range of seal, syringe barrel and piston sizes.
FIG. 12 shows an assembled device analogous to the device shown in FIG. 10 and having additional optional features. As illustrated, piston 200 comprising sleeve 240 and insert 230 is inserted within a syringe barrel 100. Sleeve 240 can comprise extension tabs 262 and insert 230 can also comprise extension tabs 260. The extension tabs present on the sleeve and the insert can assist in manipulation of the valve associated with the piston. Squeezing together of the tabs in the A direction can open the valve. Rotation of the insert relative to the sleeve (direction B) can then be performed to position the tabs to “lock” the sleeve and insert position relative to one another thereby locking the valve into the open position. To close the valve the insert can be rotated in an opposing direction and tabs 260 can be moved apart relative to tabs 262.
