体液サンプリング装置
Document Type and Number:
Japanese Patent JP3802568
Kind Code:
B2
Abstract:
A fluid sampling apparatus includes a housing member (1) which contains a lancing needle (16) used for piercing skin together with a spring member (11) for urging the needle to protrude form the housing end sufficient to penetrate the skin. A plunger (14) retracts the needle against the spring tension and a trigger member (2) engages the plunger to hold the needle retracted until released by the trigger. Stop and adjustment tabs (19) limit the depth of needle penetration of the skin and a sample container communicating with the needle receives the sample from the needle. Secondary springs retract the needle from the skin and a suction cam and plunger (22) activated upon retraction of the needle draws the sample of fluid which accumulates on the surface of the skin into the sample container.
