摘要： A mounting member for attaching a front-loading syringe to a powered injector is disclosed. The present invention may also include a plunger that has a two-piece molded core portion that is readily attachable to a plunger drive member of a powered injector. The plunger core may also be equipped with an anti-cocking flange to prevent the plunger from being axially misaligned within the syringe body which could result in fluid leakage between the plunger and the syringe body. An alignment flange may also be provided on the plunger to assist with the proper insertion of the plunger into the syringe during the assembly process. A method of manufacturing a syringe plunger is also disclosed. The present invention further includes a sleeve for clampingly engaging a heating blanket to the outer surface of a syringe.

摘要： Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. (As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector.) Alternatively, an iris-like structure may be incorporated into the front surface of the injector, for closing about the syringe upon insertion of the syringe into the injector.
摘要翻译：在前装载注射器中使用各种密封结构，用于防止溢出的流体从注射器的外表面泄漏到驱动柱塞的附近。例如，密封衬垫可以并入到注射器壳体的前表面中，用于与注射器的圆柱形主体的后圆形边缘配合。或者，密封和锁定功能可以通过注射器后端上的单个结构来执行。此外，可以通过在注射器上包括位于注射器前方的锁定结构的注射器上的非平面密封凸缘或包括注射器的两件式结构，以及用于将注射器包围的单独的泄漏停止垫圈来防止泄漏停止沿着注射器外部的流体流动。（作为该方面的一部分，或作为独立特征，注射器可以包括锁定结构前面的环形不连续的凸缘，用于为注射器提供针对注射器的机械支撑。）或者，可将虹膜状结构并入注射器的前表面，用于在将注射器插入注射器时围绕注射器闭合。

摘要： A safety syringe comprises a barrel having a grip lug with two fitting holes and two retaining holes communicating with each other; an elastic lashing member capable of retracting elastically and inwards, and having two locating pillars which are provided with an arresting head being retained in the retaining holes of the barrel, two slide confining portions being disposed at each side; a plunger having two slide pieces; a needle holder being caught and pulled by the plunger, and fitting a needle set. In use, the slide pieces of the plunger are confined by the slide confining portion of the elastic lashing member such that the plunger can not be turned. The plunger arrives at the bottom in the wake of injection such that the plunger is not confined by the elastic lashing member, and that the plunger can be thus turned to actuate the needle holder and drawn into the interior of the barrel by the plunger.

摘要： A suction chamber and a discharge chamber are defined in a front housing member. A crank chamber is defined between a cylinder block and a rear housing member. A drive shaft passes through the suction chamber and extends from a front end of a housing. The drive shaft is supported by the housing. A shaft sealing assembly for sealing the drive shaft is located in the suction chamber. In the cylinder block and a valve plate, a bleed passage is formed for connecting the crank chamber with the suction chamber. The bleed passage is inclined downward toward the suction chamber. The outlet of the bleed passage is above the shaft sealing assembly. In the suction chamber, a reservoir, which stores lubricating oil supplied through the bleed passage, is surrounds a lower part of the shaft sealing assembly.

摘要： A plunger rod for a syringe in is of integrally injection molded plastic construction having an elongated body with a coaxial end portion. An external thread extends around the end portion for threaded receipt into a plunger tip that is slidably received in a syringe barrel. A flat extends chordally across the end portion of the rod body interrupting the external thread. The plastic, of which the plunger rod is molded, is gated into the mold for the plunger rod at the flat that extends across the rod end portion, leaving a gate mark or vestige on the flat. Gating of the plastic material into the portion of the mold that forms the threaded end portion of the plunger rod achieves improved flow and improved filling of the external thread, while employing a simple and economical mold construction. The gate vestige does not interfere with threading of the plunger rod end portion into the plunger tip. The end portion of the plunger rod is cored during molding to provide a C-shaped cross section at the rod end portion, which improves dimensional stability during material shrinkage after molding.

摘要： A syringe comprises a barrel (1) having a plunger (7) in slidable and sealing engagement therewith. In order to provide an autodestruct system, so that the syringe can be used once only, being rendered disabled after one normal use, the barrel (1) has means interrupting the cylindrical surface of its inner wall in the form of grooves (10, 11) or a projection (29), and the plunger (7) has a locking means (17, 20) which operates on engagement with a groove (10, 11) or projection (29) on withdrawal of the plunger (7) to prevent further withdrawal movement. The locking means (17, 20) is provided on the head of the plunger (7) adjacent an elastomeric sealing cap (15). The locking means may comprise a pair of flukes (17) or a cross-shaped disc (20).

摘要： Safety syringe with retractable standard needle including a syringe barrel, a plunger and an injection needle. A commonly used standard medical injection needle can be firmly fitted with the needle holder in accordance with the requirement of a user. The inner wall of the internal chamber at the open end of the syringe barrel is formed with an entrance recess extending along the axis of the internal chamber. The operating end of the plunger is formed with a radially outward projecting stopper section for preventing the needle pulling mechanism of the plunger from being accidentally latched with the needle pulling mechanism of the syringe barrel.

摘要： This relates to an improved delivery system for accurately loading and controlling the delivery of flowable material to a patient. Particularly, the system may be used in the injection of hard tissue implant materials such as PMMA under pressures up to about 4000 psi. The system includes an applicator with a first column having an implant material introduction section adapted to provide for effective loading of the implant material and a second column housing a piston. The introduction section has a larger size than that of a vessel section or bore in which the requisite pressure seal between the piston and bore wall is formed. The first column may include an introduction section flared open to an included larger funnel-like opening or a separate funnel may be used that interfaces with the introduction section to facilitate the introduction of implant material. Handles on the first and second columns to be turned relative to each other to advance the columns toward each other may be provided for manual actuation of the applicator to drive implant material through a cannula and deliver implant material to a desired site.
