Abstract
A lancing device for collecting body fluid samples with a body at the end of which an endcap is arranged. The endcap has a positioning surface with an outlet opening. The device further comprises a socket to receive at least one lancet, which is interchangeably clamped in the body, a clamping device, and a release mechanism, with which the lancet is clamped inside the body. The lancing procedure is initiated with the tip of the lancet emerging through the outlet opening. An ejection device is used to eject a used lancet. The endcap is functionally coupled with the ejection device in such a way that, when the ejection device is actuated, the endcap is held pivotably on the body so that it can swing out of the path of the lancet.
Claims20
A lancing device for collecting body fluid samples, comprising:
- a) a body, at the end of which an endcap is arranged, said endcap having a positioning surface with an outlet opening,
- b) a socket to receive at least one lancet, wherein said lancet is interchangeably clamped in the body,
- c) a clamping device, with which the lancet is clamped inside the body, and a release mechanism able to initiate a lancing procedure, a tip of said lancet emerging through the outlet opening during the lancing procedure, and
- d) an ejection device to eject said lancet after the lancing procedure, wherein the endcap comprises several portions, each of said portions is pivotably connected via a separate pivot joint to said body, wherein the endcap is functionally coupled with the ejection device in such a way that, when the ejection device is actuated, said several portions pivot against each other, around an axis perpendicular to a direction of displacement of said lancet so that said several portions can move out of an ejection path of said lancet.
A lancing device for collecting body fluid samples, comprising:
- a) a body, at the end of which an endcap is arranged, said endcap having a positioning surface with an outlet opening;
- b) a socket to receive at least one lancet, wherein said lancet is interchangeably clamped in the body;
- c) a clamping device, with which the lancet is clamped inside the body and a release mechanism able to initiate a lancing procedure, a tip of said lancet emerging through the outlet opening during the lancing procedure;
- d) an ejection device, to eject said lancet after the lancing procedure;
- and
- e) a sliding element, which can be slid at least partially over the endcap while the lancet is clamped in the body, wherein the endcap is functionally coupled with the ejection device in such a way that, when the ejection device is actuated, said endcap is held pivotably on the body so that it can move out of an ejection path of said lancet, wherein the endcap comprises several portions, and wherein the sliding element when slid over the endcap engages the portions of the endcap causing the endcap to swivel out of an open position into a closed position.
