Embodiment Construction

[0053] Figure 1-11 The lancing device at is attempting to collect a blood sample. The blood collection device 1 includes a two-part housing 2, which includes an upper shell part 3 and a lower shell part 4.

[0054] The lancing device 1 extends a longitudinal extension 5 along its longitudinal axis 6 from its end region 7 to its head region 8, a nut 9 being screwed into the housing in the head region 8 of the lancing device 1 Body 2, wherein said screw cap 9 has a replaceable lancet 12 for said blood collection device 1 (see for example figure 2 ) through the through hole 10 through which the puncture needle 11 (lancing needle) passes.

[0055] In said upper housing part 3 , a pressure relief element 13 and a tension sliding element 14 are placed radially adjacent to said longitudinal axis 6 . Both the pressure relief element 13 and the tension slide element 14 protrude radially beyond the outer surface 15 of said housing 2 so that they are easily accessible manually.

Abstract

The invention relates to a lancing device (1) for taking blood samples. The device comprises a housing (2), an axially displaceable lancet holder element (32) for holding a lancet (12), a driving unit (30) including at least one piercing spring element (31) and used for driving the axially displaceable lancet holder element (32), and a tension carrying element (26) that can be fixed to a tension position (36) and is used for tensioning the piercing spring element (31). According to the invention, the fixable tension carrying element (26) is temporarily and axially fixed to the tension position (36) via a lock device (35) that can be locked to the axially displaceable lancet holder element (32).

Description

technical field [0001] The invention relates to a lancing device for taking a blood sample, the device comprising a housing, an axially movable lancet holding element for holding an exchangeable lancet, comprising at least one piercing spring element, A drive unit for driving the axially displaceable lancet holding element in the piercing direction and a tension carrier part which can be fixed in a tensioned position for tensioning the piercing spring element. Background technique [0002] It is known that conventional existing lancing devices comprise a drive unit, in particular consisting of two spring elements connected in series. In this type of lancing device, the front piercing spring element, ie the spring element facing the lancet holder to be advanced, ensures the advancing of the lancet held by this lancet holder during the piercing procedure. The rear return spring element, ie the spring element which is further away from the lancet holder to be advanced, ensures...
