摘要:
An adapter includes a syringe carrier adapted to seat at least a portion of the syringe. The syringe carrier includes at least one rearward facing abutmer member to abut at least one forward facing surface on a syringe. The syringe carrie includes an opening therein to allow a drive member of an injector to communicate forward force to the plunger through abutment without connective engagement between the drive member and the plunger. The adapter further includes a releasable mounting mechanism positioned to the rear of the syringe carrier to mount the adapter in a desired position relative to the front wall of the injector. An adapter includes a first section and a second section that are rotatable relative to each other about a hinge axis generally perpendicular to a longitudinal axis of the adapter. An adapter includes a first section and a second section that are generally the same in construction, the first section and the section being connectable to form a syringe carrier to seat at least a portion of the syringe.
摘要:
The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

The fluid injector system includes a source of injection fluid, a pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a raised projection from substantially a top end to substantially a bottom end, the elongated body configured to receive and contain the injection fluid. A fluid level sensing mechanism is operably associated with a fluid control device, and includes a support for the drip chamber body, wherein the support is adapted such that the raised projection is in operational contact with a fluid level sensor associated with the support. The fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.

A syringe includes a body having a distal end, a proximal end and a center section therebetween, a plunger movably disposed in the body, and a lip extending outward from the proximal end of the body. The outward extending lip has an outer diameter no greater than the outer diameter of the center section. The outward extending lip may extend around the circumference of the proximal end.
摘要:
A syringe includes a cylindrical body having a distal end and a proximal end, an injection section at the distal end and an expansion section at the proximal end, the injection section and the expansion section being connected by a cylindrical center section of relatively uniform outer diameter. The injection section includes a conical portion and an injection neck, the conical portion including an alignment flange extending outward from at least a portion of the conical portion. The syringe further includes a plunger movably received in the body and having a coupling end with a pair of flexible coupling members defining a slot therebetween for engaging a drive piston of an injector, the slot being substantially aligned with the alignment flange such that the alignment flange provides an indication of the orientation of the slot, the plunger seated for storage in the expansion section. A syringe has a reduced wall thickness at the expansion section such that an inner diameter of the expansion section is larger than the inner diameter of the center section for allowing the expansion section to expand under radial outward force exerted by the plunger.
