Abstract:
A vein scope and injection system for safely and efficiently locating veins to thereby provide precise venous access comprising, in combination:a monitor assembly including an image viewing surface formed as a screen in an upper plane and an image receiving surface formed as a camera in a lower plane parallel with and beneath the upper plane, the monitor assembly also including electronic components capable of producing an enlarged image upon the viewing screen of an area beneath the camera, the viewing screen being of a rectangular configuration with an upper edge and a lower edge and two parallel sided edges there between, the monitor assembly being formed with a first thickness; a support assembly including a bracket portion and an arm receiving portion, the bracket portion being in a rectangular configuration with an upper edge and a lower edge and two parallel side edges there between to thereby form an upper surface and a lower surface, the bracket portion having a central opening located centrally with respect to the screen, the bracket and opening forming an enclosure for the receipt and secure containment of the monitor assembly within the opening, the bracket assembly further having a plurality of axles coupled horizontally adjacent to the image receiving surface, the axles having a first end and a second end with the first end being coupled to the bracket portion and the second end being coupled to a roller wherein the rollers having a central aperture to receive the axle, the support assembly having a second thickness which is greater than the first thickness to thereby form a chamber between the edges of the bracket portion and beneath the camera, the arm receiving portion being of a generally U-shaped trough having an interior surface, a pair vertical side walls and a generally semicircular base region, thereby defining a region to receive an arm, the vertical side walls each having a horizontal track wherein a recess is nearly covered by an upper lip and lower lip, allowing the roller and axle combination to fit within the horizontal track of the arm receiver thereby allowing the placement of the arm of a patient in a plane generally parallel to the plane of the camera and also allowing movement of the monitor and support assembly relative to the arm receiving portion and arm; a needle handling assembly including spaced parallel guide rails coupled to the bracket portion adjacent to the lower face and extending away from the bracket portion, the needle handling assembly also including a slide member with laterally spaced apertures for being slidably received on the rails and with a central aperture; and a syringe removably positioned within the central aperture of the slide member, the syringe having a needle extending into the chamber so that the tip of the needle is located within the chamber to allow the movement of the syringe and needle and slide member along the rails for advancement of the needle toward and into a vein during the enlarged viewing of the needle and an appropriate vein of a patient to thereby provide for the precise viewing and venous access during operation and use.
