PCT No. PCT/GB93/00650 Sec. 371 Date Sep. 27, 1994 Sec. 102(e) Date Sep. 27, 1994 PCT Filed Mar. 30, 1993 PCT Pub. No. WO93/19671 PCT Pub. Date Oct. 14, 1993.A blood sampling device has a tubular body (1, 2) housing a spring loaded (7) lancet (8) whose needle (17) is initially protected by a cap (20) which projects out from the forward end of the body. A rocker-like trigger (9) is formed as part of the moulded body (1,2) and holds the lancet (8) in a retracted position when the lancet is pushed back by the projecting cap (20). The cap can then be removed by a twist and pull action, breaking it free from the lancet body, which is prevented from rotating. Pressure on the trigger (9) releases the lancet (8), which is shot forward by the spring (7) for momentary projection of the needle tip (19), and then retracts to bring the needle tip within the body. |
