  • Patent number: 6110149
    Abstract: The present invention relates to syringes for apportioning set doses from an ampoule has a dose setting and injection mechanism comprising a dose setting member which may be moved in one direction to set a dose and in the opposite direction to inject the set dose. A piston advancing mechanism comprises a piston rod and a piston rod drive, and the dose setting and injection mechanism is coupled to the piston advancing mechanism through a unidirectional coupling transmitting only movement of the dose setting member in the dose injecting direction to the piston rod drive. Operation of an air shot button enables influence on the piston advancing mechanism to advance the piston to expel an adjustable fixed volume. The air shot button is either coupled to the piston rod drive through a unidirectional coupling through which the piston rod is advanced when the air shot button is pressed, or it moves the end stop for an injection button so that this button may be pressed beyond its normal depressed end position.

  • Patent number: 5505212
    Abstract: A blood sampler comprises a small chamber having a stiletto mounted air-tightly through a flexible top wall with a pointed end of the stiletto positioned inside the chamber opposite an opening in the bottom part of the chamber. The sampler is designed to be mounted in a tool which compresses the chamber by pressing the flexible top wall against the bottom of the chamber. Further, the tool has means for imparting an impact on a blunt outer end of the stiletto to drive the stiletto further through the top wall to make its sharp end protrude through the opening in the bottom part into the skin to which the sampler may be attached by an adhesive. When the sampler is ejected from the tool, it regains its original shape, providing in the chamber a vacuum for sucking blood from the perforated skin into this chamber.
