VACUUM ASSISTED LANCING DEVICE |
摘要 |
A vacuum assisted lancing device (10) for obtaining capillary blood from body sites includes a plunger (12) mounted in a barrel or upper housing (24) that upon being pressed by a user, drives a lancet (18) to puncture skin at a body site. A vacuum member such as a diaphragm (38, 66) or bellows (66) is displaced by the plunger (12) and displaces air in the lancing device (10) to create a vacuum. The vacuum draws skin partially into the lancing device (10) causing blood to form at the puncture. The vacuum is then released and the blood is tested. |
