  • Intradermal injection device
    Patent number: 9931472
    Abstract: An intradermal injection device comprises a housing, a foot with an opening for passage of a needle; a reservoir movably mounted in the housing, and having a hollow space for holding a fluid; a hollow needle movably mounted in the housing and having a first end for penetrating the subject's skin and a second end for penetrating the reservoir, a plunger movably mounted in the housing for moving the needle through the opening for penetrating the subject's skin, and for pressing the fluid out of the reservoir. The reservoir is frictionally mounted inside the housing by first friction means, and the plunger is frictionally mounted to the reservoir by second friction means. The force to overcome the second friction is larger than the force to overcome the first friction.
