Abstract: The fluid injection apparatus is adapted for use with a syringe and includes an injector and a pressure jacket associated with the injector. The injector includes a housing defining an opening for a drive piston extendable from the housing. The pressure jacket secures the syringe during an injection procedure. The pressure jacket has a distal end defining a syringe receiving opening for receiving the syringe, and a proximal end associated with the housing and generally aligned with the opening. The apparatus includes a syringe sensor adapted for engagement by the syringe when loaded into the pressure jacket. The housing may have an engagement tab adapted to engage an engagement recess in the pressure jacket to removably engage the pressure jacket with the housing. The apparatus may have one or more light sources associated with the housing for illuminating the syringe received in the pressure jacket.

Abstract: The fluid injection apparatus for use with the syringe includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one locking member pivotally associated with the pressure jacket. The at least one locking member is movable between an engaged position preventing removal of the syringe from the pressure jacket and a disengaged position allowing insertion and removal of the syringe into the pressure jacket.

Abstract: The fluid injection apparatus for use with a syringe includes an injector and a pressure jacket assembly associated with the injector. The injector includes a housing defining a central opening and a drive piston extendable through the central opening for imparting motive forces to a syringe plunger disposed within the syringe. The pressure jacket assembly includes a pressure jacket and at least one support arm associated with and extending outward from the housing. A syringe retaining member is attached to the at least one support arm. The syringe-retaining member defines a syringe receiving slot for receiving at least a portion of the syringe. A light source is located on the support arm and faces the pressure jacket for illuminating the syringe. The syringe includes an alignment flange defining a bulged air bubble viewing window (see A). The alignment flange is used to properly orient the syringe in the pressure jacket.

Abstract: 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.

Abstract: A fluid delivery system includes a control unit having one or more devices for controlling a fluid injection, a syringe having a body and a plunger movably disposed within the body, and a syringe interface module separate from but in communication with the control unit. The syringe interface module includes a module housing, a syringe interface on the module housing that is adapted to connect the syringe to the module housing, and a drive member operable to advance the plunger of the syringe.

Abstract: An injector for use in injecting a fluid in a medical injection procedure includes a drive mechanism to pressurize the fluid; a sensor to measure a variable that is proportional to fluid pressure (that is, a direct or indirect measurement of fluid pressure); and a pressure monitor (for example, including hardwired circuitry and/or software) in communication with the sensor and the drive mechanism to stop the injection procedure when the sensor measures a value of the variable that corresponds to a pressure hazard limit. Preferably, the pressure monitor further limits power input to the drive mechanism to a power limit once the variable reaches a value that corresponds to a power limiting pressure that is below the pressure hazard limit.

Abstract: A syringe for use with a powered injector to inject a fluid into a patient includes at least a first indicator positioned on the syringe at a predetermined axial position. The distance between a rearward surface of the first indicator and a predetermined position on the powered injector provides information about the syringe configuration. The first indicator can, for example, be a rear surface of the attachment flange. An injector system includes a powered injector having a drive member and at least one sensor for detecting energy. The injector system also includes a syringe having at least a first indicator positioned on the syringe at a predetermined axial position. The energy detected by the sensor is determined by the axial position of the indicator when the syringe is attached to the powered injector. The axial position of the indicator thereby provides information about the syringe configuration.

Abstract: A secure, computer based method and system for anonymously and confidentially matching indications of interest from potential buyers and sellers is disclosed which facilitates human intervention for negotiating a final transaction between matched parties. Potential buyers and sellers independently enter indications of interest into a central processing system which operates on a network containing a secure station and a plurality of remote user terminals linked to the secure station. The indications identify a security (such as a trading equity), price, type of order, duration, and other related information. A memory at the secure station stores user data and multiple prospective transaction entries received from the user terminals. Indications of interest are compared against those already in the system to determine whether buy side and sell side orders are sufficiently similar to generate a match.

Abstract: A method and apparatus are provided for controlling the dispensing of a primary liquid from a pressurized source of primary liquid. Primary liquid is admitted through an inlet valve to a primary chamber having a primary element which is biased toward an initial position but is movable away from the initial position when subjected to the source pressure of the primary liquid. A sensor determines when the primary element has moved away from an initial position to a predetermined final position, and the inlet valve is closed in response thereto. The difference between the initial and final positions defines a predetermined dispensing volume. An outlet valve is opened to dispense the dispensing volume under the biasing force of the primary element which returns to the initial position. A sensor determines when the primary element has returned to the initial position, and the outlet valve is closed in response thereto.

Abstract: A flexible container for medical solutions is provided that includes first and second film sheets sealed together along multiple sides so as to form a pouch having an open end. An end port member is located between and sealed to the first and second film sheets near the open end of the pouch to enclose the interior of the container. The end port member has at least one integrally-formed access port for fluid communication between the exterior and the interior of the flexible container. A portion of the first and second film sheets extend beyond the end port member and are sealed together along the edges of the extended portions so as to form a protective cover for the access ports. The protective cover is detachable.

Abstract: An apparatus and method are disclosed for compounding of parenteral admixture solutions, and recirculation with the admixture solution being formed. The apparatus includes a multiple pump cassette configured for operative association with a pump driver, whereby one or more selected source solutions are delivered through a pump cassette to an associated admixture container. After pumping of each source solution, the present method contemplates that the admixture being formed is recirculated through the pump cassettes thereby diluting any source solution in the cassettes and associated tubing. In this manner, the possible mixture of incompatible source solutions, resulting in formation of precipitate, is desirably avoided.

Abstract: A solution pumping system includes a compressible pump cassette having front and rear body members, and an elastomeric diaphragm positioned therebetween. The front and rear body members are joined to each other for limited, relative movement, which movement effects compression of the diaphragm. The pump cassette is removably positionable in a pump driver of the system, which can be configured to effect compression of the cassette for use. In this way, the desired compression of the diaphragm during use can be achieved, while avoiding problems associated with compression set or load decay during storage of the cassette prior to use.
