A lancet device comprises a hollow housing defining a cavity and having a proximal end and a distal end. It also comprises a slider slideable at least partially within the cavity of the hollow housing along a longitudinal axis from an outward position to a pushed position. The slider extends outside of the cavity beyond the proximal end of the hollow housing when it is in the outward position. The lancet device also comprises a needle holder holding a lance. The needle holder is rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position. When the needle holder is in the initial position, the slider is in the outward position. When the needle holder is in the extended position, the lance extends outside of the cavity beyond the proximal end of the hollow housing. The sliding of the slider from the outward position to the pushed position urges the needle holder to the extended position. There is also a first biasing member positioned within the hollow housing at the distal end. The first biasing member exerts a biasing force against the needle holder toward the proximal end when the slider is moved to the pushed position. A second biasing member can be present in the lancet device.一種刺胳針裝置，包括一個界定了一腔並具有一近端和一遠端的中空殼體。該裝置還包括至少部分在中空殼體的腔內沿縱軸從一外部位置滑動到一推進位置的一滑動件，當該滑動件在外部位置時，滑動件延伸出腔外到中空殼體的近端之外。刺胳針裝置還包括用於握住一刺針的握針器。當從一起始位置移動到一延伸位置時，握針器可繞縱軸旋轉並沿縱軸平移。當握針器在起始位置時，滑動件在外部位置。當握針器在延伸位置時，刺針延伸出腔外到中空殼體的近端之外。滑動件從外部位置到推進位置的滑動促使握針器到延伸位置。另有位於中空殼體遠端的一第一偏壓件。當滑動件移動到推進位置時，第一偏壓件向握針器施加一個朝向近端的偏壓力。刺胳針裝置可包括一第二偏壓件。
