An x-ray film changer includes a removably mounted, passive-type cassette having no film driving mechanism and comprising a film-receiving spiral guide plate extending within the cassette in excess of one and one-half 360. degree. turns. The cassette further comprises an anvil bar for reverse bending of the guide plate when the cassette is opened, to facilitate film removal, a light-blocking gate which uncovers a film feed-in slot in response to mounting of the cassette on a film exposure device, and a combination carrying handle-latch mechanism. The film changer further includes a tachometer generator-timing circuit delay system for varying the lead time of a firing command to an x-ray generator in response to the speed of an approaching film, a transversely extending, pivotable film stop-and-orienting bar synchronized with film clamping and feed mechanisms, a film anti-bounce mechanism an indicia printing mechanism having a liquid crystal display with a backlighted electroluminescent panel, and film feed sensors for detecting film misfeeds and an unacceptable number of film "short feed" conditions in a film sequence.

A method of dispensing a hazardous pharmaceutical includes the steps of: connecting a source of flushing fluid to a first port of a fluid delivery set; connecting a pressurizing unit of a powered injector system (including a powered injector and the pressurizing unit) to a second port of the fluid delivery set; purging air from the fluid delivery set; and, after purging air from the fluid delivery set, connecting a third port of the fluid delivery set to a source of the hazardous pharmaceutical. The fluid delivery set can, for example, include a valve system or assembly to control flow of fluid through the fluid delivery set. A system for delivery of a hazardous pharmaceutical includes: a syringe in operative connection with a powered injector; a protective container to enclose the syringe during operation thereof, the protective container being adapted to protect personnel from detrimental effects of the pharmaceutical; at least one source of flushing fluid; a fluid path adapted to connect to a patient; at least one source of the pharmaceutical; and a fluid delivery set including a valve assembly to which the syringe, the source of flushing fluid, the fluid path and the source of pharmaceutical are removably connectable. The valve assembly provides flow control through the fluid delivery set such that operator contact with the fluid delivery set is not required after connection of the source of pharmaceutical to the fluid delivery set.

A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

An angiographic injector device for use in x-ray photography for delivering contrast media to a patient at controlled rates and pressures. A processor elicits injection parameters from an operator or a pre-programmed injection module, and on the basis of the injection parameters, calculates appropriate control signals for use in a closed-loop servo system to actuate the plunger of a syringe containing the contrast media. Injection parameters includes flow rate, volume, duration, pressure limit and rise-fall time of flow rate. The device also includes control circuits for inhibiting the injection device in response to a contrast media pressure limit, failure in the processor or injection control system, or upon reaching a predetermined volume of injected media. A mechanical stop member cooperates with the control circuit for blocking movement of the syringe plunger upon reaching the predetermined injected volume. Further, the device includes a self-test feature for checking the status of operational components thereof and a self-calibration feature for calibrating the servo system and position monitors.

An apparatus for measuring and detecting the pressure in a fluid being injected into a closed system, for instance, fluid being injected into a dilitation catheter, such as a balloon catheter used for the purpose of percutaneous transluminal angioplasty. The apparatus provides a pressure measuring system that includes a housing for releasably and slidably holding the barrel of a syringe used to deliver fluid into the balloon catheter; and a device for measuring and indicating fluid pressure in the syringe barrel, which is also the balloon pressure. The pressure measuring system indirectly measures pressure changes of fluid within the syringe barrel by sensing movement of the barrel as a result of fluid pressure changes. Since a pressure change is sensed by sensing movement of the syringe barrel, the only parts of the system directly contacted by the fluid inflating the balloon are the syringe barrel and syringe plunger. A control device for controlling movement of a piston within the syringe barrel also is provided.

An injector for injecting a fluid from a syringe, which includes an elongated body, a mounting member positioned on a rear portion of the body, and a plunger moveably positioned within the body of the syringe, includes a housing having a front wall and a retainer on the front wall. The retainer is adapted to cooperate with the mounting member to releasably retain the syringe on the front wall. The retainer includes a powered loader adapted to bring the mounting member and the retainer into secure engagement to securely connect the syringe to the injector. The injector further includes a powered drive member in the housing. The drive member is adapted to engage the plunger and control the movement of the plunger.

A valve system for use in a system including a first source of a first pressurized fluid and a second source of a second pressurized fluid includes a valve housing including a first inlet port adapted to be placed in fluid connection with the first source, a second inlet port adapted to be placed in fluid connection with the second source and an outlet port. The valve system further includes a backflow prevention system to prevent flow of the first pressurized fluid through the second inlet and to prevent flow of the second pressurized fluid through the first inlet port. The valve system is adapted to provide a fluid path between at least the first inlet port and the outlet port to enable fluid to be drawn from the outlet port to the first inlet port. Several of the valve systems of the present invention provide for flow from the first inlet port to the outlet port and concurrent flow from the second inlet port to the outlet port.

An angiographic injector has an injector portion which includes a rotating turret for housing two angiographic syringes in readiness for injection. The injector further employs a driving mechanism for connecting with and controlling the movement of a syringe plunger once one of the syringes is in place for injection. Through the use of guide means on each syringe and corresponding alignment means on a pressure jacket, the syringe is alignably and securely mounted within the pressure jacket on the rotating turret. Each syringe plunger is releasably connected to the driving mechanism for an injection operation, and released from the driving mechanism when the injection operation has been completed, such that the driving mechanism can be withdrawn from the syringe relative to the plunger without drawing body fluid of a patient into the syringe. Various types of plunger release mechanisms for this purpose are disclosed. The questions raised in reexamination request No.
