Abstract
A device for withdrawing blood for diagnostic purposes including a lancet and a lancet drive having a loadable elastic drive spring provided within an elongated housing. A relaxing motion of the drive spring is converted into a puncturing motion to move the lancet at high speed in a puncturing direction until its tip exits out of an opening of the housing. The device includes a transmission in the housing that has an input side that transforms the motion of a loading element along a linear loading path into a rotational motion of a lancet drive rotor to load the lancet drive rotor by tensioning the drive spring. When the lancet drive is triggered, the output side of the transmission converts a rotational motion of the lancet drive rotor, driven by the drive spring, into the puncturing motion in a direction along the main axis.

48. A lancet device, comprising:
-
a housing;
a lancet disposed in the housing and configured for puncturing movement relative to the housing;
a spring;
a transmission having a rotor coupled to the spring; and
a loading element coupled to the transmission and configured for loading movement along an axial loading path relative to the housing;
wherein, the transmission converts the loading movement of the loading element into a first rotation of the rotor about an axis disposed substantially parallel to the axial loading path, the first rotation tensioning the spring and thereby loading the lancet device. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A blood lancet device for withdrawing blood, including:
-
a housing;
a lancet being movable in the housing;
a rotor disposed in the housing and having a spring connected thereto;
a locking device for locking the spring in a loaded state; and
a transmission connected to the housing, the transmission converting a linear motion of a loading element into a first rotational motion of the rotor about a rotational axis that is substantially parallel to a main axis of the housing to load the rotor by tensioning the spring. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)

75. A blood lancet device for withdrawing blood for diagnostic purposes, comprising:
-
an elongated housing having a main axis running lengthwise relative to the housing;
a lancet being movable in the housing;
a lancet drive having an elastic spring configured to be locked by a locking device in a loaded state; and
a double sided rotary/translatory transmission provided in the housing including an input side for converting a motion of a loading element that moves along a linear loading path, into a rotational motion of a rotor, the rotor being rotated about a rotational axis running substantially parallel to the main axis to load the rotor into the loaded state by tensioning the spring. - View Dependent Claims (76, 77, 78, 79, 80, 81)
