1. A lancing apparatus comprising:
- a housing separately formed with a cylindrical member having an open front end for contact with skin, the cylindrical member further having a rear opening,a lancet disposed in the housing and movable to advance in a first direction from a deeper portion in the housing behind the rear opening of the cylindrical member toward the front end of the cylindrical member through the rear opening of the cylindrical member, andan analysis component disposed in the cylindrical member between the front end and the rear opening of the cylindrical member for contact with skin even before lancing the skin with the lancet;
wherein the analysis component is supported for movement relative to the cylindrical member separately from the lancet in a second direction opposite to the first direction upon receiving a force from the skin in the second direction while the analysis component keeps contact with the skin in a lancing operation;
wherein the cylindrical member is telescopically supported by the housing for movement relative to the housing in the second direction separately from the analysis component upon receiving a force from the skin in the lancing operation.

Abstract
The present invention provides a lancing apparatus (A) which includes a lancet (3) which is movable to advance in a first direction from a deeper portion in a housing (2) toward a front end of a cylindrical member (8) and an analysis component (4) disposed in the cylindrical member (8). The analysis component (4) is movable in a second direction opposite to the first direction upon receiving a force in the second direction. When skin (S) bulges, the analysis component (4) moves in the second direction following the bulging of the skin, whereby blood (b) bleeding from the skin (S) is properly introduced to the analysis component (4).

12. A lancing apparatus comprising:
-
a housing separately formed with a cylindrical member having an open front end for contact with skin, the cylindrical member further having a rear opening, a lancet disposed in the housing and movable to advance in a first direction from a deeper portion in the housing behind the rear opening of the cylindrical member toward the front end of the cylindrical member through the rear opening of the cylindrical member, an analysis component disposed in the cylindrical member between the front end and the rear opening of the cylindrical member for contact with skin even before lancing the skin with the lancet; a determiner for determining whether or not a sample is introduced to the analysis component, a negative pressure generator for generating negative pressure in the cylindrical member, and a controller to relieve the negative pressure generated in the cylindrical member when the determiner determines that the sample is not introduced to the analysis component within a predetermined time after the lancing apparatus is advanced toward the front end of the cylindrical member, wherein the analysis component is supported for movement relative to the cylindrical member separately from the lancet in a second direction opposite to the first direction upon receiving a force from the skin in the second direction while the analysis component keeps contact with the skin in a lancing operation; wherein the cylindrical member is telescopically supported by the housing for movement relative to the housing in the second direction separately from the analysis component upon receiving a force from the skin in the lancing operation. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A lancing apparatus comprising:
-
a housing separately formed with a cylindrical member having an open front end for contact with skin, a lancet disposed in the housing and movable to advance in a first direction from a deeper portion in the housing toward the front end of the cylindrical member for lancing skin, and an analysis component supported on a holder in the cylindrical member ahead of the lancet in the first direction, the holder having a lancet passing hole, the lancet in a non-lancing position being located behind the lancet passing hole of the holder, the lancet advancing through the lancet passing hole of the holder for lancing the skin, wherein the analysis component is supported for movement together with the holder relative to the cylindrical member separately from the lancet in a second direction opposite to the first direction upon receiving a force from the skin in the second direction for following bulging of the skin in a lancing operation; wherein the cylindrical member is telescopically supported by the housing for movement relative to the housing in the second direction separately from the analysis component upon receiving a force from the skin in the lancing operation.

21. A lancing apparatus comprising:
-
a housing; a cylindrical member slidably fitted in the housing and having an open front end for contact with skin, the cylindrical member further having a rear opening, a lancet disposed in the housing and movable to advance in a first direction from a deeper portion in the housing behind the rear opening of the cylindrical member toward the front end of the cylindrical member through the rear opening of the cylindrical member, and an analysis component disposed in the cylindrical member between the front end and the rear opening of the cylindrical member for contact with skin even before lancing the skin with the lancet; wherein the analysis component is supported for movement relative to the cylindrical member separately from the lancet in a second direction opposite to the first direction upon receiving a force from the skin in the second direction while the analysis component keeps contact with the skin in a lancing operation; wherein the cylindrical member is configured to telescopically slide relative to the housing in the second direction separately from the analysis component upon receiving a force from the skin in the lancing operation.
