Abstract

A system suitable for collecting a body fluid, in particular blood from a body region of a person to be examined which comprises a lancing device which is suitable for holding a lancet, a lancet magazine for storing two or several lancets which has a transport device for the lancets and has an opening into which the lancing device can be inserted to remove a lancet from the lancet magazine, and two or several lancets, and which comprises a method for removing a lancet from a lancet magazine in which a lancet located in the lancet magazine is manually or automatically transported into a removal position in the interior of the lancet magazine, a lancing device is partially inserted into the opening provided in the lancet magazine in the process of which the lancing device automatically grips the lancet located in the removal position when it is partially inserted and the lancing device with the gripped lancet is removed from the lancet magazine.

Claims

1. A system that is suitable for collecting bodily fluid from a region of the body of a person to be examined, the system comprising:

a lancing device which is suitable for holding a lancet, the lancet including a needle;

a lancet magazine for storing a plurality of lancets, the lancet magazine comprising an opening into which the landing device can be inserted to remove an individual lancet from the lancet magazine in a first direction substantially parallel to a longitudinal axis of the lancing device; and

a transport device adapted to travel within the lancet magazine in a second direction substantially perpendicular to the first direction to transport lancets in the lancet magazine;

wherein a second opening through which protective sheaths of the lancets can be ejected is located in the lancet magazine in addition to the opening into which the lancing device can be inserted to remove a single lancet from the lancet magazine.

2. A system that is suitable for collecting bodily fluid from a region of the body of a person to be examined, the system comprising:

a lancing device which is suitable for holding a lancet, the lancet including a needle;

a lancet magazine for storing a plurality of lancets, the lancet magazine comprising an opening into which the lancing device can be inserted to remove an individual lancet from the lancet magazine in a first direction substantially parallel to a longitudinal axis of the lancing device; and

a transport device adapted to travel within the lancet magazine in a second direction substantially perpendicular to the first direction to transport lancets in the lancet magazine;

wherein a pin is located in the opening of the lancet magazine into which the lancing device can be inserted to remove a single lancet from the lancet magazine, and the pin engages in a guide groove in the tip of the lancing device which is inserted into said opening and thus causes a rotation of the lancing device or a part of the lancing device about its longitudinal axis.

3. A system that is suitable for collecting bodily fluid from a region of the body of a person to-be examined, the system comprising:

a lancing-device which is suitable for holding a lancet, the lancet including a needle;

a lancet magazine for storing a plurality of lancets, the lancet magazine comprising an opening into which the lancing device can be inserted to remove an individual lancet from the lancet magazine in a first direction substantially parallel to a longitudinal axis of the lancing device; and

a transport device adapted to travel within the lancet magazine in a second direction substantially perpendicular to the first direction to transport lancets in the lancet magazine;

wherein a guide groove is located in the opening of the lancet magazine into which the lancing device can be inserted to remove a single lancet from the lancet magazine, and a pin is located in the tip of the lancing device which is inserted into said opening so that the pin engages the guide groove and thus causes a rotation of the lancing device or a part of the lancing device about its longitudinal axis.

4. A system that is suitable for collecting bodily fluid from a region of the body of a person to be examined, the system comprising:

a lancing device which is suitable for holding a lancet, the lancet including a needle;

a lancet magazine for storing a plurality of lancets, the lancet magazine comprising an opening into which the lancing device can be inserted to remove an individual lancet from the lancet magazine in a first direction substantially parallel to a longitudinal axis of the lancing device; and

a transport device adapted to travel within the lancet magazine in a second direction substantially perpendicular to the first direction to transport lancets in the lancet magazine;

wherein the plurality of lancets in the lancet magazine each include a sterile tip and a protective sheath surrounding the sterile tip.

5. The system of claim 4, wherein the protective sheath is removed when the lancing device is inserted into the lancet magazine.

6. A system that is suitable for collecting bodily fluid from a region of the body of a person to be examined, the system comprising:

a lancing device which is suitable for holding a lancet, the lancet including a needle;

a lancet magazine for storing a plurality of lancets, the lancet magazine comprising an opening into which the lancing device can be inserted to remove an individual lancet from the lancet magazine in a first direction substantially parallel to a longitudinal axis of the lancing device; and

a transport device adapted to travel within the lancet magazine in a second direction substantially perpendicular to the first direction to transport lancets in the lancet magazine;

wherein the opening has a substantially circular shape.
