Body fluid sampling implement and body fluid sampling method
First Claim
1. A body fluid sampling implement used by installing a piercing needle therein and allowing a body fluid to be discharged by piercing a body fluid sampled portion with said piercing needle, comprising:
- a body storing said piercing needle and having an opening allowing said piercing needle to pass therethrough; and
a contact part fixedly installed on said body so as to surround an outer periphery of said opening and pressed by said body fluid sampled portion when said body fluid sampled portion is pierced by said piercing needle, wherein an inner surface of said contact part has a portion tilted in such a manner that in a direction approaching said opening the tilted portion comes closer to a central axis of said opening.

Abstract
A component measuring apparatus (body fluid sampling implement in this invention) used by installing a piercing needle therein and allowing blood (body fluid) to be discharged by piercing a blood sampled portion (body fluid sampled portion) with the piercing needle, comprising a body storing the piercing needle and having an opening allowing the piercing needle to pass therethrough and a contact part fixedly installed on the body so as to surround the outer periphery of the opening and pressed by the blood sampled portion when the blood sampled portion is pierced by the piercing needle. The contact part has a function to specify a shape near the blood sampled portion when the blood sampled portion is pressed against the contact portion. In addition, the contact surface (inner surface) of the contact part (3) is tilted so as to near the center axis of the opening toward the opening of the body and formed in the shape of a truncated cone in side view.

7. A body fluid sampling method for sampling a body fluid comprising:
-
pressing a bodv fluid sampled portion against a contact part which is fixedly installed on a body having an opening and which possesses an inner surface having a portion tilted in such a manner that in a direction approaching said opening the tilted portion comes closer to a central axis of the opening, said body storing a piercing needle, the contact part surrounding an outer periphery of said opening, piercing said body fluid sampled portion with said piercing needle in a condition where said body fluid sampled portion is pressed against said contact part to obtain a sample of body fluid from the body fluid sampled portion. - View Dependent Claims (10, 11, 12, 13)

8. A body fluid sampling method carried out by use of a body fluid sampling implement comprising:
-
a body storing a piercing needle and having an opening allowing said piercing needle to pass therethrough; and
a contact part fixedly installed on said body so as to surround an outer periphery of said opening, an inner surface of said contact part having a portion tilted in such a manner that in a direction approaching said opening the tilted portion comes closer to a center axis of said opening, said method comprising;
pressing said body fluid sampled portion into close contact with said inner surface of said contact part, operating said piercing needle so as to pierce with said piercing needle a portion of said body fluid sampled portion which is projected into said body through said opening; and
sampling body fluid discharged from the portion of said body fluid sampled portion that is pierced by said piercing needle. - View Dependent Claims (9, 14, 15)

16. A body fluid sampling implement comprising:
-
a piercing needle adapted to pierce a body fluid sampled portion to discharge body fluid from the body fluid sampled portion, the piercing needle being housed in a tube;
a body adapted to receive the tube and possessing an opening allowing said piercing needle to pass therethrough when said tube is received in the body; and
a contact part against which is to be pressed the body fluid sampled portion to permit the piercing needle to pierce the body fluid sampled portion, the contact portion possessing spaced apart openings at opposite ends and an inner surface extending between the openings, at least a part of the inner surface of the contact portion being configured as an inclined surface, the inclined surface having opposite ends, one of the ends of the inclined surface being located closer to the body than the other end of the inclined surface, the one end of the inclined surface located closer to the body being positioned closer to a central axis of the opening than the other end of the inclined surface. - View Dependent Claims (17, 18, 19)
