Abstract:
1. A body fluid sampling device for sampling body fluid from a living body via a body fluid sampling surface, said device comprising: a housing having a hermetically sealable internal region; an elastically deformable section arranged at a part of a partition wall separating the internal region from an outside and adapted to be applied to the body fluid sampling surface; and a needle arranged in the internal region so as to needle the body fluid sampling surface and cause body fluid to exude from the body fluid sampling surface; wherein the needle is arranged at a position adapted to needle through the elastically deformable section when the elastically deformable section is pressed by the body fluid sampling surface to produce a through hole in the elastically deformable section and further needle through the body fluid sampling surface, wherein the elastically deformable section has a mechanism for generating negative pressure in the internal region when the elastically deformable section returns to an original position from a pressed position, and wherein the elastically deformable section is configured to elastically deform towards and press against the needle, thereby causing the needle to needle therethrough, when the elastically deformable section is applied to the body fluid sampling surface.
