Lancing devices having lancet ejection assembly

A lancing device for use with a removable lancet, comprising:

• a housing;
• a lancet carrier slidably disposed within the housing and adapted to receive the lancet;
• an ejection slide mounted to the housing and configured to eject the lancet from the lancet carrier;
• and
• a locking member contacted by the ejection slide to move the locking member in a first direction into blocking engagement with the lancet carrier to prevent forward movement of the lancet carrier when the ejection slide ejects the lancet;
• wherein the locking member contacts the housing on one or more bearing surfaces-apart from the ejection slide, the locking member being configured so that substantially all of the force exerted on it by the lancet carrier is transmitted to the housing via the one or more bearing surfaces.
