摘要： Blood lancet device for withdrawing blood for diagnostic purposes, in which with the aid of a lancet drive (3) in a housing (1) a lancet holder (6) with a lancet (34) positioned in it and moveable along a predetermined, straight puncture path is moved until the tip (35) of the lancet emerges from the outlet (84), in order to produce a wound in a body part adjoining the outlet (84). The lancet holder (6) also serves to retract the lancet (34) into a position in which the tip (35) is again positioned within the housing (1). In order to make possible a puncture involving especially little pain, the lancet drive (3) has a rotary/sliding transmission system (4) whose input side (16) is formed by a transmission member which is rotatable about an axis of rotation parallel to the predetermined puncture path. This input-side transmission member (5) of the rotary/sliding transmission system is coupled with the elastic drive element (9) of the lancet drive (3) and converts a torque transmitted to the transmission member (5) into a longitudinal displacement in the direction of the predetermined puncture path, which is transmitted to the lancet holder (6). .Iadd.A method for withdrawing blood for diagnostic purposes using the blood lancet device is also presented..Iaddend.

摘要： The present invention provides a method of improving reagent elution from a reagent strip comprising a handle on one end which is affixed an absorbent carrier impregnated with a reagent. The absorbent carrier is pressed against the handle by a thin mesh which is stuck or sealed on to the handle on opposite sides of the carrier.Another mesh is between the carrier and the handle. When the carrier is immersed in a liquid, the meshes improve the elution of the reagent into the liquid.
