A single use lancing device comprising:
- a housing defining a cavity;
- a needle assembly comprising a needle and a needle holder, the needle assembly located within the cavity;
- a release member;
- and
- a spring arranged to bias the needle assembly in a forward direction relative to the release member;
- wherein the release member comprises retaining arms and is movable relative to the housing between a primed position in which the retaining arms are arranged to cooperate with the housing to retain the needle assembly in a primed position and a deployed position in which the retaining arms are arranged to release the needle assembly to deploy the needle;
