  • Publication number: 20180296771
    Abstract: A fluid injection system and a fluid verification system for confirming that a syringe, containing a fluid for injection, is fully filled with fluid and neither has free space (i.e., air) near the distal end thereof when the syringe is provided in an upright position nor contains air bubbles. Imaging processing techniques and systems are also provided to determine various injection parameters and to verify the type and certain properties of fluid that is present within a syringe.

  • Publication number: 20180256882
    Abstract: A medical connector assembly for establishing a fluid connection between a first medical device and a second medical device includes a multi-use connector and a plurality of single-use connectors connected in series. The multi-use connector has a proximal end opposite a distal end along a longitudinal length thereof. The plurality of single-use connectors each have a proximal end opposite a distal end along a longitudinal length thereof. The distal end of the multi-use connector is releasably connected to the proximal end of a first of the serially-connected single-use connectors. When a second of the serially-connected single-use connectors is disconnected from the first single-use connector, the first single-use connector remains connected to the multi-use medical connector as a sterility retaining cover.

  • Publication number: 20180161496
    Abstract: A rolling diaphragm syringe includes a proximal end having an end wall, a distal end having an open-ended discharge neck, a sidewall extending along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end, and unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.

  • Publication number: 20070129705
    Abstract: A medical connector includes a body defining a lumen for fluid flow through the medical connector. The medical connector includes a luer member and an annular member disposed about the luer member. The annular member includes internal and/or external engagement structures. The medical connector may be provided on the outlet of a syringe or on a catheter. A fluid path is disclosed including a first section and a second section. The first and second sections may each include a medical connector to provide a removable connection with a syringe and a catheter, respectively. The medical connector may provide a removable connection between the first and second sections. A fluid delivery system is disclosed including an injector, a syringe operatively associated with the injector, and a fluid path connecting the syringe and a source of injection. The medical connector may provide a removable connection between the syringe and fluid path.

  • Publication number: 20070106208
    Abstract: A system for injecting an injectate into patient includes a first pressurizable container for holding the injectate; a patient interface in fluid connection with the first pressurizable container, the patient interface being adapted to pass the injectate into tissue of the patient; a powered injector in operative connection with the first pressurizable container to pressurize the injectate; a controller system in operative connection with powered injector; and a stereotactic localization frame adapted to be placed in operative connection with the patient interface to assist in controlling localization of the patient interface. A system for processing cells (and/or other injectate components) includes a container and a plunger adapted to be slidably positioned within the container. The system includes at least one inlet port through which a fluid can enter the system and at least one effluent port through which an effluent can exit the system.

  • Publication number: 20060184124
    Abstract: An injector for injection a fluid into a patient, including: a first pressurizing mechanism adapted to operatively connect with a first fluid container to pressurize fluid therein; at least a second pressurizing mechanism to operatively connect with a second fluid container to pressurize a fluid therein; a single drive; and a transmission to control how power from the drive is distributed to the first pressurizing mechanism of the first container and to the second pressurizing mechanism of the second container to control injection of fluid from the first container and from the second container. The drive can, for example, be an electric motor or other drive.

  • Publication number: 20060129104
    Abstract: A syringe for use with a powered injector to inject a fluid into a patient that includes a length of material adapted to transmit or propagate electromagnetic energy therethrough. The length of material includes at least a first indicator positioned along the length of material. The first indicator is adapted to interact with at least a portion of the energy being propagated through the length of material in a manner that is detectable. The presence (or absence) of the first indicator provides or corresponds to information about the syringe configuration. The indicator(s) of the present invention can, for example, provide information about syringe configuration by the number and/or position thereof. A plurality or set of such syringes can be provided, with the configuration of each such syringe being represented by the presence or absence of indicator(s) of that syringe.

  • Publication number: 20050113754
    Abstract: A syringe includes a body and a plunger movably disposed within the body. The plunger includes a wall having an inner surface and one or more inwardly projecting flanges disposed on the inner surface of the wall. Preferably, the inner surface of the wall defines a retaining shoulder formed along an axial plane thereof and the inwardly projecting flanges are radially spaced along the interior surface of the wall and extend in a longitudinal direction proximal to the retaining shoulder. The syringe may be used with an injector including a drive member. The drive member preferably includes at least one retaining member adapted to engage the retaining shoulder of the syringe plunger to allow the drive member to retract the plunger with the body of the syringe. Further, the drive member preferably includes one or more outwardly extending flange members adapted to be engaged by the inwardly projecting flanges of the syringe plungers.

  • Patent number: 5549200
    Abstract: A swab dispenser system is provided that includes a reusable outer receptacle and a replaceable refill container insertable therewithin. The outer receptacle is formed with a fin projecting vertically upwardly and centrally positioned on the bottom panel of the receptacle. The fin has a horizontal length greater than a width thereof. The refill container on its bottom wall also includes a fin. The fin of the refill container has a hollow interior for form-fittingly receiving the fin projecting upwardly from the receptacle bottom panel. Function of the fin is to allow a consumer to properly orient the refill container when placing same into the receptacle. The fin also functions to direct swabs into a proper arrangement when they are being factory filled into the container. Furthermore, the position and geometry of the fin maximizes the number of swabs fillable into the container.
