A blood sampler comprises a cup shaped positioning part having a bottom (1) and a sidewall (2) and a sampling part having a bottom (4) and a sidewall (5). In the bottom (1) of the positioning part there is provided a central opening (9), which at the outer side of the cup is surrounded by a spacing ring (3). The sampling part has a needle (8) centrally through is bottom (4), which needle has at the outside of the sampling part a sharp end and inside the sampling part a sample collector (10). The sampling part fit displaceably into the positioning part with the sharp end of its needle (8) facing the opening (9) in the bottom (1) of this positioning part, but is by a snap lock (6, 7) releasably locked in a position with its bottom (4) near the upper edge of the positioning part. A cup shaped transparent cap (11) fits with its open end into the open end of the sampling part. In use the spacing ring (8) is pressed against the skin (12) by a finger (13) pressing the cap (11) until the snap lock (6, 7) releases and the sampling part passes into the positioning part with its needle (8) projecting through the opening (9) in the bottom (1) of this positioning part into the skin (12). |
