  • Patent number: 7458962
    Abstract: A device for injecting fluid from a pre-filled cartridge is provided. The device includes a needle for piercing a patient. After an injection, the needle can be retracted to prevent inadvertent contact with the contaminated needle. A needle retainer releasably retains the needle in the retracted position. The needle can subsequently be re-extended to administer a subsequent injection. After the cartridge is emptied, the cartridge can be removed, if desired, and replaced with another cartridge for additional injections. Alternatively, the needle can be substantially permanently retracted into the device and safely disposed of in a sharps container.

  • Publication number: 20070107609
    Abstract: This invention concerns a juicer, that is a machine for extracting the juice from fruit and vegetables. Such machines are used domestically, and also commercially in restaurants, cafes and juice bars. The invention comprises an electric motor, a shredder mounted for rotation by the motor, a feed tube to deliver pieces to be juiced to the shredder for juicing, wherein the feed tube has an inner diameter of more than 75 mm, and three, or more, inwardly directed formations are arranged to constrict the interior of the feed tube. The inner diameter of the feed tube may be large enough for a typical apple to pass through it whole such as 85 mm or more. The inwardly directed formations serve to prevent the insertion of a hand or arm into or through the feed tube despite its large diameter.

  • Publication number: 20070078432
    Abstract: An adjustable infusion injection apparatus which is designed to be used in conjunction with a surgically implanted infusate injection port. The apparatus utilizes a catheter assembly and an introducer needle assembly. The catheter assembly is to be installed on the skin of the patient in alignment with the port and the introducer needle is to be inserted in conjunction with the catheter assembly to insert a catheter within an internal chamber of the port and then the introducer needle is then removed with the catheter to then be used to inject medication from an inlet tube. During installation a movable portion of said catheter assembly can be moved to abuttingly be in contact with the skin of the patient.

  • Patent number: 7004929
    Abstract: A device is provided for injecting fluid from a pre-filled cartridge. The device includes a needle and a hollow barrel that holds a pre-filled cartridge. A needle retainer releasably retains the needle in an extended position so the needle can be inserted into a patient. A plunger in the rear of the barrel cooperates with the cartridge to expel fluid from the cartridge during an injection. After an injection, the needle is automatically retracted into the barrel when pressure is released from the plunger. A locking mechanism locks the contaminated needle and cartridge in the barrel after needle retraction. After use, the device may be safely disposed of in a sharps container.

  • Patent number: 6977622
    Abstract: A method, an apparatus, and a computer program product for electromagnetically designing a shaped-reflector multibeam antenna (100) are disclosed. An initial configuration of the multibeam antenna (100) for given beam directions is provided of reflectors (110,120) shaped with an initial reflector shaping process (612) and feeds of an initial specification (614). The initial reflector shaping process (612) is an iterative optimization process for increasing the focusing of optical rays incident on the multibeam antenna from the given beam directions (100). A second iterative optimizing process consisting of optimizing (620) radiation patterns of feeds (140A-140D) and optimizing (622) surface shapes and sizes of reflectors (110,120) is used to reduce beam spillover, improve beam shapes and obtain beams with gain radiation patterns within required upper and lower bounds.
