摘要:
The present invention provides prefillable syringes and injectors for use therewith that expand and/or facilitate a variety of medical procedures involving the injection of a liquid medium. In several embodiments, the present syringes and injectors enable the use of current syringe materials at higher pressures than previously attainable or the use of other materials not previously usable with current high pressure-syringe and injector designs. In one embodiment, a syringe comprises an elongated cylindrical main body having a first pair and a second pair of mounting flanges encompassing collectively an arcuate length equal to at least approximately 180° of the circumference of the rear portion of the cylindrical main body for releasably mounting the syringe in a desired position relative to the front wall of the injector housing. Injectors for use with such syringes comprise a housing having a front wall and a retainer on the front wall which cooperates with the first and second pairs of mounting flanges of the syringe to releasably mount the syringe on the injector.

This invention relates to a process for manufacturing prefilled syringes where at least one of the syringe components is manufactured in at least a class 100 environment. The process includes the steps of manufacturing syringe components, such as the barrel and plunger substrate, within at least a class 100 and MCB-3 environment; manufacturing syringe components, such as the plunger cover and tip seal in an environment less clean than a class 100 environment; decontaminating the plunger cover and tip seal; lubricating at least one of the barrel, plunger substrate, plunger cover and tip seal; assembling the barrel and tip seal to form a barrel/tip seal combination; assembling the plunger cover and plunger substrate to form a plunger; filling the barrel/tip seal combination with a predetermined amount of fluid; and final assembling of the prefilled syringe by inserting the plunger into the barrel/tip seal combination. When the syringe components are manufactured at different locations, each component is tripled-bagged to maintain the component substantially free from contaminants, and transported to an assembly site where the components are unpackaged and assembled into the barrel/tip seal combination and plunger. When filling and final assembly of the barrel/tip seal combination takes place at a location separate from its assembly site, the barrel/tip seal combination is tripled-bagged to maintain it substantially free from contaminants, and transported to a filling and final assembling site for filling and final assembling into a prefilled syringe.

The plunger systems for use in an injector-actuated syringe of the present invention include a dynamic wedge seal which improves the sealing engagement between the plunger cover and syringe barrel, and flexible capture members extending from the rear surface of the plunger which permit the engagement and disengagement of the plunger from the injector drive means at any plunger position within the syringe. Further, the plunger systems include a contrast saving tip which expells the injection liquid from the syringe tip.

A fluid delivery system includes a fluid container, two or more pressurizing chambers in fluid connection with the fluid container, a drive mechanism in operative connection with the two or more pressurizing chambers to pump fluid from the fluid container and an outlet in fluid connection with the two or more pressurizing chambers. Each of the two or more pressurizing chambers is formed from a flexible, resilient material that is adapted to be compressed to pressurize fluid therewithin.

An integrated radiopharmaceutical patient treatment system is disclosed including a patient support platform with an associated patient stimulus apparatus, an imager proximate the patient support platform, a radiopharmaceutical fluid delivery system for infusing a radiopharmaceutical fluid into a patient, a patient monitor to be associated with a patient, and an integrated system controller operably associated with the patient stimulus apparatus, imager, radiopharmaceutical fluid delivery system, and patient monitor to control and coordinate their operations. Within the patient treatment system the radiopharmaceutical fluid delivery system may be included comprising a radionuclide supply module, a radiopharmaceutical processing module, a quality control module, a patient injection module, and a controller. A hazardous fluid handling system including a docking station and a hazardous fluid transport device adapted to detachably dock with the docking station is further disclosed.

A system for producing a contrast-enhanced medical image of a patient includes a source of a contrast or enhancement medium, a pressurizing unit in fluid connection with the source of contrast or enhancement medium, an energy source operable to apply energy to a region of the patient, an imaging unit providing a visual display of an internal view of the patient based upon a signal resulting from the energy applied to the region of the patient, and a control unit. In an embodiment, the signal is affected by a condition of the contrast or enhancement medium in the patient. To control the procedures, the control unit adjusts the condition of the contrast or enhancement medium in the patient based upon the signal. A communication interface preferably enables information between an injector subsystem and an imaging subsystem.

An injection system includes a fluid delivery system, a drive mechanism, a controller and a tubing set. The fluid delivery system includes a fluid container and a pumping mechanism having an inlet in fluid connection with the fluid container and an outlet. The tubing set is adapted to be placed in removable fluid connection with the outlet of the pumping mechanism and a patient. The drive mechanism is in operative connection with the pumping mechanism to pump fluid from the fluid container. First and second information stores, such as bar codes or RFID tags, are associated with the pumping mechanism and the tubing set, respectively. The controller is in operative connection with the drive mechanism and adapted to read the first information store and the second information store to at least partly control the operation of the drive mechanism based thereon.

A syringe for use in a pressurized injection of a fluid includes a syringe barrel including a polymeric material having undergone expansion via blow molding. An inner diameter of the syringe barrel can, for example, be sufficiently constant (over at least a portion of the axial length of the syringe) that a plunger slidably positioned within the syringe barrel and in generally sealing contact with an inner wall of the syringe barrel can be used within the syringe barrel to generate a pressure of at least 1 psi within the syringe barrel. In several embodiment, the inner diameter of the syringe barrel is sufficiently constant to generate a pressure of at least 100 psi, at least 300 psi, or even at least 500 psi within the syringe barrel. A method of forming a syringe includes the steps of: injection molding at least one polymeric material to form a preform; placing the preform into an blow mold die; and expanding at least a portion of the preform while heating the preform within the die to form a barrel of the syringe. The syringes can be formed to withstand relatively high pressures as described above. The at least one polymeric material can, for example, be polyethyleneterephthalate, cyclic olefin polymer, polypropylene, polystyrene, polyvinylidene chloride, polyethylene napthalate and/or nylon.
