Abstract: Adapters for use with an angiographic injector. A face plate adapter includes a channel for receiving a rearward end of a syringe. First and second mounting flanges on the adapter overlay a portion of the channel, to cooperate with mounting flanges on a rearward end of the syringe, so that the syringe mounting flanges may be inserted between the adapter mounting flanges, and then rotated in the channel behind the adapter mounting flanges, to thereby lock the syringe to the adapter. The adapter further includes one or more locking pins, which in a locked position extend across the channel, to block the syringe from rotating in the channel and thereby prevent a syringe from being dismounted from the adapter. A collar incorporated in the adapter interacts with a drive ram of the injector to move the locking pins into their locked position whenever the ram is forward of a rearwardmost position.

Abstract: A medical valve has a resilient member that is forcibly expanded to an expanded volume from a normal volume. Specifically, the valve operates in a closed mode that prevents fluid flow, and an open mode that permits fluid flow. To these ends, the valve has a housing having an inlet and an outlet, and the noted resilient member within the housing. The resilient member and housing form a fluid channel between the inlet and the outlet. The fluid channel at least in part extends through the resilient member. The fluid channel has a given portion formed by a variable volume portion of the resilient member. The variable volume portion has a normal volume when in the closed mode, and an expanded volume when the open mode. The expanded volume is greater than the normal volume.

Abstract: A needleless injection site comprising a housing defining proximal and distal ends and including a reseal member disposed therein. The reseal member has an elastically openable and closable aperture formed therein, and normally resides within the housing in a closed position wherein the aperture is in a closed configuration. The reseal member is deformable such that the application of distally directed pressure thereto will cause the reseal member to distally advance within the housing to an open position wherein the aperture assumes an open configuration. The removal of the distally directed pressure from the reseal member will cause it to resiliently return to the closed position wherein the aperture assumes the closed configuration.
