  • Patent number: 10780229
    Abstract: A low-waste needle and syringe assembly for injecting a fluid into a patient is provided. The syringe has hatch marks printed on the outer wall of the body to indicate the amount of fluid and/or the concentration of the fluid contained in a fluid chamber of the syringe. A syringe tip defining a substantially frusto-conical interior void extends from an end wall of the syringe. A needle hub holds a needle and is configured so that the hub can be selectively and securedly attached to the syringe. A frusto-conical member of the needle hub matingly engages the frusto-conical void of the syringe tip when the hub is secured to the syringe, forming a fluid-tight seal. A plunger positioned in the fluid chamber can be depressed by a user, and a piston cap attached to the plunger urges fluid in the chamber out of the chamber through the syringe tip and into the needle. The piston cap matingly engages the end wall of the syringe so that substantially all fluid is urged from the chamber to the needle.

  • Patent number: 8708970
    Abstract: An injection needle assembly is presented having a tubular needle holder with distal and proximal engagement means, a tubular cap having proximal inner and outer engagement means, a tubular needle cover having a first engagement means arranged to cooperate with the proximal engagement means, and second engagement means arranged to cooperate with the proximal outer engagement means of the cap. The needle cover is arranged to be displaced from a first position wherein the second engagement means and the proximal outer engagement means prevents the needle cover and the needle holder to be axially displaced by a linear displacement, to a second position wherein the needle cover and the needle holder are distally displaced. The proximal inner engagement means of the cap and the distal engagement means of the needle holder prevents the needle holder to be proximally displaced but allows the needle cover to be distally displaced.
